I’m looking for some creative ideas regarding termite damage repair. My skill level is above DIY but not quite master carpenter. I’ve done all types of my own remodels so I’m not afraid to get into something like this.
Last year I purchased a single family 1920’s fixer in Indianapolis. I’ve done a lot of work on it, but have been procrastinating on the big item: severe termite damage across the entire front of the house, a swath about four feet by 25 feet. The sill plate and joists are essentially dust, as well as the subfloor under the oak floor strips. But they did not touch the oak floor strips (top nailed) for some reason. The result is the floor still looks great, but you can feel that something is wrong by the way it bounces when you walk over it. What surprises me is that the whole thing hasn’t caved in yet. I knew the damage extent when I purchased the place, but the deal was too good to pass up.
Anyway, I’m trying to figure out some clever way to repair all the damage underneath, without ripping up any of the flooring strips. Everything is accessible through the crawlspace, about 3ft tall. In a different part of the house, I had to do a similar repair. At that spot, I tried to gently take up the floor strips and repair the subfloor. But no matter how gentle I was, they ended up broken, cracked and chipped. I took the old nails out and laid back down, but it just looks really crummy.
Has anyone ever repaired a floor like this from underneath? What if I could rip out all the stuff underneath, leaving the top nails in the flooring, and build a new subfloor just touching the nail bottoms: Then I could squeeze some of that epoxy floor leveler stuff into the void– would that work or am I nuts? I am wide open for suggestions here. Many Thanks.
