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.
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!
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 UA-cam. Great resource.
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.
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 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.
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
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.👍
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.
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.
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.
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….
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. 👍
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.
@@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.

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?
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.
@@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 UA-camr that finished his basement and had to learn it all because he was from Ohio or something.
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!
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
Really interesting and informative video! I see you are going to put a chipboard floor down. Is it possible or recommended to replace old floorboards on my landing with chipboard flooring? About 5.5m long and 7 strips I have binned.
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
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 👍
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.
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 🤔
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 .
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.
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.
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.
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
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?
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
I have the same style wood framed 20's house. We did all the air bricks, cleaned them and replaced as they were crumbling. problem we are having is the concrete kitchen floor, stone door plate? plinth? lintle? dunno the name, the stone that goes under the door, when it rains really hard ie summer downpour or most of the winter water is pooling up inside and soaking the carpet. we re pointed the wall to the paving but its still happening, when I dug out the pointing i think the previous owner have paved too high now instead of digging out the old layer and i think the brickwork under the paving needs pointing, do you think this would be a job I could do as, like everyone, we have no money so a builders not an option right now. I was thinking pull up the paving slabs, dig away from the wall, clean, point, replace paving slabs, any other suggestion what I can do would be wonderful as we are just googling to learn at this point.
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.
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
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
That new concrete floor is well below DPC level, so any moisture in that floor (and the brickwork it’s touching) won’t get past the damp proof course and therefore it won’t get anywhere near the new timber floor. That’s my understanding anyway. The issue before was the old concrete floor was partially above the DPC (known as bridging) so the moisture could travel as far as it wanted up the walls.
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. 👍
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
Tidy work. Rock solid with the t&g. With that nibbled slab in the corner under the side (ex garage) door, would it be worth chem-fixing some sort of connection into the slab, so the new and old floors are joined and cohesive? Possibly some small rebar and then use your trimmer beam as formwork for a bit of concrete? Dunno, might be more hassle than it's worth...
At the moment I have the T&G running right to the edge and it's solid. There will be a final solid floor over the T&G eventually so I might re-visit that at some point. Watch this space! 👍
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.
Hi Andy very good work as always! And thanks for showing us your way of building a new suspended timber floor. Just wondered why you didn't run the main floor joists into the cut outs in brick walls at either end of joists (with damp membrane underneath of course)? Rather than using the support ledger boards. Is it due to - Building regs, new practices, easier using ledgers?? Many thanks for your video and valuable time and information...
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.
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!

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. 👍
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.

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.

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
This is great. One question, why does the new concrete floor underneath the timber not attract moisture to go up the walls like the previous one?
That new concrete floor is well below DPC level, so any moisture in that floor (and the brickwork it’s touching) won’t get past the damp proof course and therefore it won’t get anywhere near the new timber floor. That’s my understanding anyway. The issue before was the old concrete floor was partially above the DPC (known as bridging) so the moisture could travel as far as it wanted up the walls.
hello, Is the concrete base needed? Would it not be fine to just install new joists?
Looks great mate, can you show how you lay the chipboard flooring down, about to do mine 👍
Already down I'm afraid but might cover that when we do the extension. Just used 4 x 50mm turbogold screws. 👍

At the moment I have the T&G running right to the edge and it's solid. There will be a final solid floor over the T&G eventually so I might re-visit that at some point. Watch this space! 👍
you can buy a false wasp nest, which wiil stop wasp from inading. great work andy.
Interesting! Will look in to that! 👍
Which way will you lay the boards
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.
@27:15 How is that insulation held in place?
Looks like small wood ledges screwed into the joists
Yup, 20x20mm timber battens brad nailed in place, quite a snug fit too.
@@GosforthHandyman I used Roof battens to do the same
Hi Andy very good work as always! And thanks for showing us your way of building a new suspended timber floor. Just wondered why you didn't run the main floor joists into the cut outs in brick walls at either end of joists (with damp membrane underneath of course)? Rather than using the support ledger boards. Is it due to - Building regs, new practices, easier using ledgers??
Many thanks for your video and valuable time and information...
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.
