Does the replacement of subflooring require a construction permit? Would doing that myself screw up my homeowners insurance or resale value of my home?

Do it yourself if you know what you are doing. Not that hard.

Almost certainly not but why not just call your local jurisdiction to find out?

Wut? If you frick up the subfloor and it affects the flooring I would think that would affect your resale value. Not sure why this is even a concern other than that.

No. It's not hard to do. What's wrong with it?

It's most likely 4 by 8 OSB or 3/4 plywood panels. Just unscrew them, put new panels in place and screw the new ones down. Not much more difficult than that.

Unknown plumbing leak led to warped floors and probable mold. Drying it out helped with the warping, but with this Summer's record wetness and humidity it warped like crazy.

Man, that's tough. Plumbing issues all fixed? I'm assuming you have to replace your flooring as well. Mold would be my biggest concern. One tiny little spore left and you'll have mold again.

If I'm doing under the existing roof I'm not getting a permit.

If you do it correct it shouldn't mess with resale value.


You'll need a shite ton of screws, I would screw everything into place with just a few screws to hold it then go rent a deck screw gun to screw it down really good. I think it has to be screwed every 8".

Had the exact same thing in an old house a few years back. When we pulled up the subfloor we found some of the floor joists had also rotted out. Have you been able to inspect below the subfloor yet? It could turn into a bigger job than you think.

Also, make sure when you're done that you get some adequate airflow under the house. Our biggest problem was that years ago someone had closed in a walkway between the house and the garage. That cut off one side of the house... and it had a brick half-wall on the front which cut that off. Essentially 2 of the 4 sides of the house had no path for airflow. I ended up cutting some holes in the brick along the front and installing louvers with electric fans on a timer to help pull air under the house.

We'd first assumed that it was dampness from beneath the house. The main reason for the extensive damage was that every flooring expert that we brought in said that it was due to poor air flow. Since the house existed 50 years without problems, I found it hard to believe but added fans beneath the house anyway. Finally, we had a plumber check for leaks. Turns out one of our showers had a leak at the drain and water was getting into the flooring.

We ended up finding a small drain leak as well. I think part of the problem was that the lack of airflow caused the water to just pool up. If the underside of the house had been better ventilated I doubt it would have been as bad as it was.

I recommend doing what we did. Fix it and sell. Old houses are a pain in the arse.

ETA - we fixed everything and ended up renting the house for a while. Over time the excessive moisture under the house caused a couple of other spots to sink in/settle and we ended up with some sagging. We didn't feel like paying for everything to be leveled and ended up taking a hit on that when we finally sold. By the time we sold it I was just ready to get rid of that piece of shite.

DO NOT USE OSB AS SUB-FLOOR.

You're welcome.

Especially if there is a possibility of moisture problems in the future.
