Good to see that someone actually understands the need for subfloor ventilation and how a lack of it leads to damp walls which is NOT so called rising damp! Well done and keep it up.
Thank you! The condition of the rest of the floor is testament to how important good ventilation is. 👍👍
I see a lot of obsession with dpc. ftr Holland do not use dpc's & they are essentially under water!
How to notice the difference between rising damp and lack/poor ventilation
I've watch videos of other house restorers, and they all agree that old houses were not built to be hermetically sealed chambers. The materials need to breathe. Trapping moisture will cause rot and disintegration.
Again I'm impressed with the attention to details that no one will ever see. Perhaps overkill, but 100 years from now it will still be rock-solid. Your great-grandchildren will appreciate your work. I can only imagine how a house-flipper would have put in that floor!
Exactly right. Lack of ventilation is a killer, especially in older houses. Certainly hope this will still be around in 100 years! 😁👍
We have certainly found that out in our Victorian house. My son did a good job of plastering a few walls after our chimney leaked with lime plaster and using lime wash paint. Seems to be good and dry so far. He’d not done any think like that before, all learnt from RUclips. Great resource.
Highlight of my day watching these!
Thank you! 👍
What a great job you have done Andy. Practical, tidy and well thought out.
Thank you! Glad that one is done! 😁
Belt and braces is an understatement. Looks great mate. 👍
I know, Mrs Mac said I should have my lederhosen out. 😂
If only all contactors were as meticulous as you Andy we would not need rogue traders would we, doing a great job mate, you and your family Stay Safe now !!!.
Thank you Brian! All good here! 👍
Hi Andy, get mouse mesh for your vents, stops the beasts and still provides plenty of ventilation for the void 👍
Yup, done. 👍😁
Looking good, Andy. If it's worth doing, it's worth doing well! Or as Mike Holmes might say, if it's worth doing, it's worth overdoing! LOL
Cheers Rob! Exactly. 😁👍
Yes you go that right!! Like it!
Thank you so much for posting this up. I'm no builder but I have an engineering back ground. I just needed to know roughly how to put the floor in as I have a similar project to do. It doesn't look overly difficult to do. I agree on the ventilation part too, damp is a killer to timber. That looks like an old wasp nest, one thing to stop them, ant powder where they're coming in and out. They'll get it on their bodies and take it back to the nest.
Nice to see Mrs Mac getting stuck in & taking a share of the labour. It is always a godsend to have someone helping out when you have tedious, repetitive movement type tasks like clearing all that junk.
Too right! She's there behind the scenes nearly as much as me. Makes a huge difference and nice to have some company too! 😁

Amazingly thorough. Fantastic work!
Cheers!
You are a very clever man Andy. Thanks again for sharing 🌞
Thank you! Lots of Googling. 😂
Good job very well done! This is going to be a very nice house beautifully modernised home Congratulations on a very professional job.and Thank you for sharing
Thank you! I think it will be as good as a 100 year old house can be! 😁👍
Andy well you certainly are doing a bulletproof job, very tidy and well thought out with due regard for maintaining an airflow. It is probably too late but looking at the next stage - if you are insulating with celotex I can recommend using the tracksaw - I have done it recently and achieved air tight fits.👍
5:20 great seeing insulated hot water/heating pipes.
bit of a tip, put some fine mesh on the inside of the air brick as bloody wasps and bees love using them to get under your floor to make a nest.
It's really difficult to get to the back of the air bricks unfortunately, but I think I'll just do the mesh on the outside and spray them red or something. 👍
As a Canadian this type of flooring looks so wild! We have basements, or at least slab. So cool to see different building methods in each climate.
Cheers! Very jealous of your basements over there! 😁
I recently moved to a place where the ground is Spanish for 'cement' - we have a little bit of gravel on top of bedrock here, so the houses are concrete slabs on the ground. Before this I lived where the ground was adobe clay and the water table was a few feet down (every basement required pumps to give the concrete a chance to set), and a slab on grade was a terrible idea there. It's very interesting to learn about good ways to build in different places.
Skills! That's a work of art, well done!
Cheers bud!
You have done a great job Andy, well done great video, thanks
No worries - cheers!
For anyone curious, bitumen is asphalt in the US. Sometimes we call it bitumen too. Floor is solid. Wish I knew more about floating floors or their variants. It’s all just cement basements up in the cold north of Minnesota. I know they use many different building south of me. Like that crazy floating wall stuff in Colorado is madness.
Interesting! Love hearing about building techniques in other parts of the world. 👍
@@GosforthHandyman From a home builder website “Colorado is known for expansive soils due to the presence of bentonite in the soil composition, which swells with moisture or freezing temperatures. This movement can shift the entire foundation and result in structural damage to the home.” They hang basement walls from the joists and leave about a two inch gap above the floor. Always thought it was interesting. There was some woodworking RUclipsr that finished his basement and had to learn it all because he was from Ohio or something.
Cracking job mate. I agree that good ventilation is massively important.
Cheers!
Brilliant job.......that's how a job should be done.
Cheers Paul!
I love this Series Andy and you have ripped the house right back to its barebones now known its all structurally sound now. I bought my home September and all though its only 27 yrs old I haven't a clue what's underneath its fabric, at least you do and you can sleep safe at night known its sound. my next job is the garden and a 16ft square foot decking plinth. keep up the hard work buddy the reward will be worth it. And if you ever sell the home just post these videos on right move haha it will sell in hours.
Thank you Neil and good luck with yours! It's nice once you know a house this intimately. There's not much of it I haven't seen now. 😁
@@GosforthHandyman 'If you ever sell it' hmm we'll see!
12:50 lol. Thanks sir! this is so much interesting than my class!!
Nice outcome from lots of hard work.
It's funny that the joist hangers and placement of supports look sketchy in places but there is no other solution and no other way around it.
Good professional looking job of flooring system and water pipe system!
Cheers! Rock solid and that's the main thing. 😁
Love your videos. I've just started watching all your renovation ones. I just wondered what was the song playing during this video, it was beautiful.
That old house is gonna be better than new!
Really impressive work.
Thank you! 👍
now that's what i call a great job done
Thank you! 👍
Nice tidy job mate!
Cheers bud! 👍
Great job! Building codes are often scoffed and so pleased you followed them as best you can in the situation. I wonder if codes were followed in Surfside, Florida! Only time will tell.
Indeed! That's horrific what's happened over there! 😬
@@GosforthHandyman Not clear yet but would you live in a 12 story building built on reclaimed wetland and sand? I know you understand the importance of good foundations.

Excellent as usual Andy, thank you for sharing. Re a previous comment, the song is ‘Everything Stops’ by Christine Smit, a lovely song, can’t beat a bit of “ Country Music”. Great choice, thanks.
Yes, it is Wildflowers, featuring Christine Smit
Cheers! 👍👍
Great job , a nightmare to do but think you made the right decision to do it
Cheers! Yeah, glad we did it. 👍😁
On the exterior air bricks you could always add a moisture detector fan. have them all blow the same way so u would get direct airflow. Its similar to what we put on non encapsulated crawl spaces here in the states.
I used the blackjack paint for the joist ends saves time wrapping in dpm.
Superb job. No flaws with that floor👍
Thank you Nick! Hope it lasts another 100 years! 👍
Nice work and thanks for sharing this with us take care
No worries - cheers bud! 👍
@@GosforthHandyman 👍🏻
It's not just shear strength with nails vs screws. In the US where most buildings are wood framed nails are required because nails will flex as the building moves whereas screws are more likely to break or tear out.
Cracking job as always. If you get ANY damp in those floors I'll eat my nice new cordless circular saw!
Thank you and congratulations on the tool purchase! 👍😁
Brilliant video, thanks!
I have learnt a lot watching the series. so thank you. I would be interested in a brief explanation about setting the correct levels of the floor. Did you use the hall floor and the outside door, and importantly, were they both at the same level?
Everything is referenced off the hall joists. The outside door is actually slightly higher but I'll sort that when we have a garage back. 👍
Great job , really enjoyed watching 👍my rear extension has timber suspended flooring , its really bouncy in the middle & has a noticable bow , im assuming its been poorly installed , going to investigate further when i pull the flooring up , hopefully i can just pack it up & support it in places 👍
I watch you tube a lot and Gosforth handyman and Aquaholic are the best two channels on here that I have seen.
+1 for Aquaholic. You may also like 'The Restoration Couple'
Haven't seen Aquaholic - will check it out! Restoration Couple is excellent. 👍
Check Charlie Diyte as well, another top bloke
It's surprising how many air bricks on the outside of houses are lower than the ground level. Nicely done that work 👍
Cheers! Yeah, luckily all at a decent level here. 👍
Plant some lemongrass, spearmint, or cloves in the area of the vent bricks. I would put them in pots in the area because these are all plants that take off in ridiculous amounts and will consume your flower beds if not watch like a hawk.
Definitely belt and braces approach , you should look up span tables for roofs and floors and you would realise that floor ain't going no where . When you put your floor down it will tie everything in and you will have next to nothing in the way of flex , cracking job mate
Defo, looked up the table for these... then went for slightly bigger ones so I could fit the insulation in. 😁👍
Top notch job! I wouldn't have gone to all that trouble lol
Cheers! All worked out! 😁
You can do a barn dance on that new floor.
Whenever I constructed a new deck, I would jump up and down on it and dance across it to see if it moved. They never did and my customers thought I was nuts, but never had anyone complain about the construction.
Too right! Finally got the deck down today and was jumping up and down on it. 😂
Expertly done, as usual
Cheers Tahir! 👍
It's great work no doubt. Next time when you will have ability to do it just put dpm between any wood and concrete it will help a lot
Very nice job.
Cheers Ray!
Very nice work as usual...
Cheers bud! 👍
Terrific job.
Cheers Mark!
Just found your channel, so far really informative so thank you for doing them. I’m a inexperienced DIY’er so love to learn!
Class work as usual.
Thank you! 👍
I had bother with woodlice coming in through air bricks and used the mesh stuff, solved the problem instantly which I was happy about. Might not be ideal for airflow but my airbricks are pretty much at ground level so fighting a losing battle anyway as water more than likely gets in during heavy rain, will have to get that sorted some day.
Yeah, defo try to drop the ground level if you can. Solves a world of problems. 👍
Great work thank you. I have learned a lot from you.
Perfect execution! But in this instance, I wonder if filling it with gravel and building a concrete slab wouldn't have been cheaper and faster. Even if damp was an issue, there was enough depth for a proper cellular glass insulation
Great job,
thanks useful vid. I recently did unerfloor insulation to my ground floor but struggled wih the stairs as couldn't lift the floorboards there.
So clean
Cheers!
Good job
Informative video, many thanks.
Great floor that mate! I’ve got to sort my living room suspended floor out when I get a chance. Got a lovely bounce the one end. It was a new floor 10 years ago but the people who did it didn’t exactly make a great job like you… what are the bolts and washers you used to bolt the timbers to the brick wall around the perimeters? Cheers. Marc
Big M12 wall bolts. 👍
Qs:
1. U also do the hall way? Or just where people will sit?
2. If u don't do all the floors would there be a temp gradient= condensation?
3. How thick is the floor cement usually in the old houses?.
4. Any rebar in the cement?
TIA
Ventilation is now possible to regulate in easy automated fasion by using insectsafe self regulating vents that take temperature as below plus 5 celsius closed
Even better is to close when damp to outside
Insulation is not done as in sweden we have a much hasher climate
With the difficultly seeing the air-brick in that external wall local to the stairs (@23:20) from the inside… I’d try sticking a high powered flood light in front if it (at the external face) maybe at night and then look from below the floor space internally to see if any illumination makes it through…. Should give an idea of it’s porosity if nothing else….
Yeah, I need to take another look when I have a few more floor boards up as it's weird not to have an open brick. I might have missed it. 👍
Top stuff as usual Andy :)
I know little about insulation (underfloor and roofing) so would love to see a vid on that at some point!
Cheers! Yup, got a vid planned for the insulation. 👍
Cheers Andy, look forward to it :)
you can buy a false wasp nest, which wiil stop wasp from inading. great work andy.
Interesting! Will look in to that! 👍
With the airbrick that is under the stairs wait until it’s dark and try shining a torch through it and see where the light comes through at the other wnd
Defo! Will have the floors up a bit closer to there soon. 😁
I did not see how you dealt with the rotting plates under the supporting wall? Wonderful workmanship throughout!
Cheers! Old wall plate, no longer needed - taken out and replaced with brick. See the vid where the structural wall nearly fell down. 👍😁
Looks a nice job. Two questions: 1) how do you guard against mice setting up home and destroying the foam pipe insulation? (In my experience mice will always find a way in!
2) how do you avoid flex and creak in the floor sheeting where it is placed down on joists with metal hanger straps sitting proud of the top, as in the corner you showed?
Will like to know that too,as I'm doing a similar project this month
I might be wrong but in the kitchen were the two concrete slabs are may have been a pantry the mat have been two walls with a stone slab on they used to store items on to keep cool as some sort off fridge i know my gran has one in her old house and we had one in the house we are in now
Thanks for another great vid. Love your belt and braces approach to everything. My thoughts regarding the wasps are perhaps put some dried thyme or eucalyptus in the area they would enter, they don't like that stuff. Don't know if it would work for any long period as the oils would eventually dry out, but if the wasps are working on memory (who really knows how a wasps mind works) perhaps they won't pass on to their offspring the fact that your underfloor is a lovely place to nest🤔🤔🤔. Just one thought... You cut wooden spacers to support your joists after measuring with plastic spacers... Why did you use the plastic spacers? They'd not be susceptible to damp, so one problem solved. Asking cos I know you've thought about it and I don't yet understand your thought process and am open to a valuable lesson👍👍
Cheers! It's holding the plastic spacers in place that's the problem. They tend to shatter with brad nails so as the floor naturally contracts a bit over time they can fall out. So I prefer timber here. 👍
Can't fault you on a belts and braces job. Just one thing stuck out for me though. When you were using the push stick on the table saw. The kickback is going to happen mostly on the material between the fence and blade. You should be using the push stick to stop that coming back.
i had woodworm in my house 2 joists replaced, all timber treated. the air bricks were covered with garden waste and dead bushes. the house was built in 1939 so god knows how long those bricks have been covered for to get to that state. Yes ventilation is important
We were lucky with my childhood home, victorian 'suburban villa'... decorative cast iron air bricks had encouraged people to actually maintain them and keep them clean over the years
Woodworm is a nightmare. Think all beetle damage has been removed but constantly on the look-out! 👍
good job! thanks for sharing, I was just curious subfloor ventilation is really good but how about protection for the rodent infestation ? I think there should be some fine mesh or grilles added to the openings 🤔
Hello Andy. The thin concrete under the floor we would call "ratproofing" and is common here in California. We would likely put a sheet of 6 mill poly down first. For the sleeper wall, did you pour the concrete any deeper there as a footing for the sleepers? Also, did you allow much time for the damp earth to dry or use fans to help? I like your solution to the rotted joists around the doorway, very clever. Your solutions for the various problems overall are ingenious, IMHO. 👍👍 Enjoying the series, thanks.
Those braces you bent that are screwed into concrete to support the floor, are they Simpson? Good video outlining a level floor over wonky concrete! Thank you and I have the same dewalt saw stand (older 744 saw) - it’s amazing and sturdy. 👍
You wiped the excess glue UNDER the floor??? LOL If anyone here in Canada is looking for a great contractor I will give your name. Great job as usual
Ha ha thank you! I couldn't leave that glue! 😁
Amazing level of detail in your videos and the work you are carried out - I do wonder what the final cost of such work would be if we were hiring you on commercial terms.
Hi, re airbricks, we had the local council remove one and whateved they did 'touch wood' ie the wooden ships of England no more have appeared. However if you go to Amazon they sell several sorts of airbrick anti-insect + anti-rodent air brick covers along with a glue sold as separate item. Be interesting to see how you get on with this.
Cheers! Yeah, going for the mesh before the wasps come back. 😁
Thinking above and beyond the building regs is fine with every normal building inspector. (not the occasional bad apple) As electricians we often get the argument about insulation vs downlights on flat roofs. Most are quite happy to compromise provided they don't 'see' it
(to explain, 150mm insulation may be 'required' but 100mm where there's a 50mm deep SELV downlight isnt going to make the building fall down or cause an extinction event)
Exactly, I think most are quite reasonable with this sort of stuff. Especially with this being an older house, sometimes you have to work with what you've got. 👍👍
@@GosforthHandyman yep most are sensible people, the 'i have more power than you types tend to cause too many problems for THEIR superiors to last long... loving this series btw :D truly looking forward to new uploads
the trick with laws, is to know which ones can be bent, and which can't... [anonymous, misquoted]
Bolting timbers together, did you use bulldog connectors in-between? Our spec, from the structural engineer, was hex round hex bolts and flat plate washers. With the double-sided
bulldog connectors in-between. Good video, BTW .
Great job Andy! Really enjoying the series. We've put some rodent mesh on our air bricks, I read that mice can fit through a pencil sized hole, and we had a lot of mice droppings under our floor so I can believe it! 👍
Cheers Keith! Yeah, I've found the odd mouse skeleton under the floors but nothing active (yet!). I know they can squeeze through amazingly small gaps. Rodent mesh might be a plan as that's probably fine enough to put the wasps off too. 👍
@@GosforthHandyman we had mice under our floors in winter last year, it was horrendous. There were probably three died, maybe four and the smell was overwhelming. Had to rip down a stud wall to find the source of the issue (after phoning both a plumber and electrician as we had no idea what the smell was). We found a small gap where a mouse was getting in, and an entry point on the outside of the house (not an air brick, just a tiny hole). It was a one way trip and they couldn't get back out, so just died. Managed to eventually drill through the floor in the partition where a hidden cistern is housed (luckily, otherwise it would have been an expensive vinyl/amtico floor lift) and slipped a shop vac down to hose up the dead rodents. We were probably six weeks all in with a couple of rooms out of action because of the eye watering stink.
@@ricos1497 Yikes! What a big problem caused by such a little critter.
Great job as usual Andy.
Can I ask, why did you make wooden packers instead of just using the plastic ones? I'm not knocking your method, just wondering what your rationale is. I've used those packers many times on my own jobs and have always found them to be so practical and so easy. Mind you, I don't have a table saw so that method isn't really an option for me.
Hi Andy
When can we expect to see more on the studio?
A quick way to test if that original air brick is functional would be to run a leaf blower through it from the outside and feel how much air reaches through
Good tip! I don't actually own a leaf blower. 😁
@@GosforthHandyman yeah I mean any large fan would work. Possibly an air output on a wet and dry vac if it has one or better yet some canned smoke
Looks great! I'm a big fan of insulating floating floors just to make them sound less hollow at the very least. One question is why did you bury the studio power cables under the cement? Is it a requirement? I like the idea of keeping cables accessible if they ever need any attention down the line, I appreciate they are already buried bellow a ton of earth outside but that can be dug up if needed.
It's in a duct so easy enough to get out and I needed to duct the fibre (separate duct) to stop it getting damaged, so just put both in the same little trench - it's very shallow though. 👍
One does hope you do not intend to leave holes that size for air flow
With respect to those screws versus nails, and the support for the floor - I think you've got a belt and braces there.....and a second belt and a second pair of extra heavy duty braces. Oh, and a third belt and probably a third and fourth and probably fifth pair of Kevlar braces just to make ABSOLUTELY sure...!
You could put a black hole on that kitchen floor and it would say 'is that all you've got....!!
Hi Andy, we've got a very old thatch cottage in West Berkshire. Unfortunately the house was never looked after in its most recent years and we need to redo the whole ground floor, no air flow etc. We were considering a concrete slab or limecrete floor, but what you've done interests me a lot. Is this a costly exercise in the UK? Our footprint is very small and I can't see this taking many weeks to complete. Would love to know real world costs per square metre or some other form of measurement to understand what a builder/carpenter would charge to completely rebuild a suspended floor.
If you just put a circular sign with a picture of a wasp in black ink on a white background, with red border and single cross through it alongside the hole that should solve your insect problems.
I'll try that. 🤣
Have you poked a stiff wire through the airbrick in the porch, see if it will go right through under the stairs?
