So you are willing to pull up the entire system, excavate a foot or two of dirt and then pour a proper basement slab? Including vapour barrier, etc?

A basement/cement company that specializes in moisture mitigation will be your best place to shop. They are experts at this. It is what they do. And while they are there, get them to work on the brick (?retaining wall?). It has moisture indicators that require more work. Masonry experts may have to be called in for that. It will all be part and parcel to what needs to be done.

And the wood rot will have to be completely exposed, removed and then replaced with appropriate materials.

Good luck. This is a BIG project. And you won't see a stick of it once it is done and the walls are all covered up.

Do I need to replace this subfloor? *Please Help!*

Jerry, that was my initial concern when I first saw the linoleum because I remember the issue arising when I was replacing my kitchen floors and few companies were willing (or able) to take them up because of the old linoleum. I eventually put wood floors on top of it. My contractor did not seem concerned at my suggestion that asbestos might be present. He deflected my comment by saying "There is asbestos in the insulation" and I didn't pursue it. The portion that has the linoleum is approximately 5' x 7'. Oh boy, this opens a real can of worms. I was planning on tile with radiant heat. Do you have any suggestions as to how I should proceed with this?

OSB is much better today than even 5 years ago. The glues/binders used are improved. In most building applications, OSB is a better choice than plywood---which has gotten progressively worse, IMHO. I recommend screwing any subfloor material for installation---even ring shank nails can loosen in flooring applications. The best solution for eliminating future squeaks is to use 15 pound roofing paper(the cheapest) or rosin paper(more expensive) between the old floor and the new OSB. In your case, using 3/4" T&G OSB will be all you need for the carpeted areas. The reason for the underlayment(1/4" birch ply) used for sheet vinyl is so the floor can be made smooth and level---no bumps/etc. showing through the flooring. Almost every man made flooring manufacturer recommends roofing felt/rosin paper installed under their product. And most require a leveled subfloor. That can be done with leveling products on an OSB subfloor(less expensive usually than underlayment).

There is definitely nothing under it... a few boards are split and completely fell away, and we can see the joists and some sort of paper barrier beneath.

subfloor replaced?
Q

Except I accidentally hit the post but too soon..🤣😂 So my question is the hardwood floor that we're taking is 3/4 in. The new LVP we will be putting in is only... 5 - 12 mm (I haven't bought it yet apparently flooring is hard to find in stock right now). So do I ask the handyman installing it to raise the level of the subfloor or do I just stick with a reducer. Turns out I have a reducer where the wood in the hallway meets the laminate in the laundry room already (I included a picture for example). Of course the reducer was put in when the wood floor was so it matches and I'm not sure what kind of reducer I would find now to put between the two rooms. Thoughts?

Is that the project? I was asking whether or not that was your plan?

What is your plan at this point? Where is this home? What are code requirements where you are?

I agree it's a big project that's why I'm taking it on. you should have seen the 3 layers of drywall and laminate before the exposed brick. I do plan on leaving the exposed brick in bathroom . I'm planning on that later. right now is the floors.

OK....the moisture mitigation (both cement slab and brick walls) must be done at the same time. And the mold remediation needs to be done before that.

And then removing and replacing ALL WOOD THAT IS touching or EXPOSED to raw earth (including in the walls, floors, under doors, etc) must be removed and replaced. That must be done BEFORE the floors/moisture/mold remediation is done.

Any/all drywall or plaster that shows any moisture contamination/mold must be removed and replaced. That gets done with the WOOD replacement gets done.

And just for some fun and excitement, you MUST TEST for LEAD and ASBESTOS! If the house or materials are OLDER than 1978 (and it looks MUCH older than that) you WILL HAVE both products in or on any surface you see in those photos.

The remediation must be done professionally. Again, a remediation company that is HIGH END can do ALL THE WORK you need to do BEFORE you pour a cubic inch of concrete.

Where are you located?

That is a teardown and rebuild.

And Sophie is getting at something that is a strong option = tear down.

It is HIGHLY POSSIBLE that the "fix" = $100,000 or higher. And that does NOT include plumbing upgrades (if you TOUCH IT you MUST BRING IT to code) or electrical codes (if you TOUCH IT you MUST BRING IT up to code).

And then you have to FINISH the space = $15K - $30K.

Imagine what can be done on your property if you tear down ($30,000) and rebuild for the same amount = $100,000.

Yeah I'm having a discussion now with a few companies on the options. Just a little background I'm in the construction trade, not entirely clueless. I appreciate the opinions but I dont think this is a tear down and those numbers are quite inflated. 30K for a teardown...wont cost that. 100k for a house in my city is a pipedream most house builds here are 400K+ if this was a suburb of cleveland perhaps.

Not running a shady rebuild was looking for recos on cement guys, I know what needs to be done here. I'm pulling permits already and this work needs to be done.
