Subfloor Repair

Not looking to completely remodel a room? Boise Custom Remodels can take care of major or minor repairs throughout your home.
We are experts at repairing subfloor damage cause by the most common problems that Treasure Valley home owners face. 
Subfloor is the layer between your floor joists and your floor covering. It is that hard layer that is underneath your tile carpet or hardwood. Usually it’s made out of plywood or OSB panels. Homeowners in the Treasure Valley are no stranger to subfloor damage. With so many older homes with aging materials coupled with rain, snow, and freezing temperatures it’s no wonder that subfloor damage due to moisture is a very common problem that Idaho residences must combat..
The most typical cause of subfloor damage is moisture. That moisture usually comes from excess humidity. Normally not too much of a problem for us here in Boise. Or it can come from a leak in your pipes or a hole in your home’s exterior. This is far more common.

Unlike many problems that are visible or cause an immediate problem, subfloor damage can be hard to notice if you don’t know what to look for. It is one of those problems that, if caught early, can be relatively inexpensive and quick to repair. If you’re wondering if your subfloor is damaged look out for some of these signs and symptoms:

Any unevenness in your floor.

This applies to all different kinds of flooring types. If you notice a dip or a squishy spot under your carpet or hardwood floor it could mean that there are early signs of deteriorating panels. This unevenness could present itself in the form of bouncy floors, too. If your hardwood floor starts to feel like a springboard that gymnasts use, it has begun to detach itself from the subfloor, which now needs to be replaced. You may also notice a phenomenon called “cupping” in a wood floor. This is because the wood is expanding from the moisture and cannot expand side to side, so it has expand up or down.An unevenness in your floor will also cause your tiles to crack. Since tile is made of stone it is not flexible at all. If your subfloor isn’t rigid enough to support them they will start to break. 

Smells like trouble. Trust Your Nose...

Trust your nose when looking for moisture damage. If you detect the unmistakably musty smell of wet, rotting wood it is highly likely that you are dealing with water damage. Unless you are a blood hound sniffing out exactly where it’s coming from, using smell alone would be tough and will require an inspection from a qualified professional. 

Wobbly Toilet, Sink or Tub

One of the most clear-cut signs that you’re subfloor is rotting is a wobbly toilet. When your toilet was installed it was fastened to the subfloor with a series of anchors. This is almost always caused from a slow leak in your toilet or other plumbing in your bathroom. We can guarantee that 100% of the time these types of leaks do not fix themselves and it’s important to call us as soon as possible so we can limit the damage spreading.

A good subfloor will last 20 to 30 years even with some exposure to moisture. If it is protected from moisture and made from high quality materials it can last the life of the home. But just like a good roof that lasts 20 to 30 years, if it is not properly protected, that lifespan will be reduced. Keep on the lookout for visible signs of rot and these symptoms that we’ve talked about above with special attention paid to exterior doors that are exposed to the elements, especially ice, under windows, and if you’ve ever had a leaky roof, underneath that leak.
