There are several problems that can cause a sagging or sloping floor, which is one of the reasons why fixing a sloping floor is difficult. Foundation issues, deteriorating wood supports (especially sills, which rest on the foundation footer), improperly installed joists or sub-floors, and other issues can all cause a floor to slope or sag. In many cases, fixing a sloping floor is an expensive and lengthy operation. It might also be difficult to find the right company to do the job.

Many older homes have problems with sloping and sagging floors. In a lot of cases, the owners of these homes simply ignore the problem or pass it off as a normal part of having a classic house. Though a sloped floor might indeed bring some character to a house, some of the issues that can cause them can lead to other problems down the road. If your home has floors that are sloped and sagging, it’s a good idea to have a professional evaluate what, if anything, needs to be done.

Identifying the Root Cause

Since this operation can get very expensive and involved, unless you know a contractor that you trust 100 percent to identify the problem, you might consider hiring a structural engineer for the diagnosis. By hiring a structural engineer who will not have any part in the repair process to evaluate your sagging or sloping floor, you can be sure that the conclusion will be unaffected by the prospect of a profitable contract. He or she will also be able to advise you on the type of contractor your should hire to do the job, which can be confusing as some of the root causes of sagging and sloping floors can fall under different categories.

Fixing a Sloping Floor

If a professional has examined your floor and determined that its cause is something that could compromise the integrity of your house’s structure, you may be able to fix the root of the problem and leave the floor as is. If your sloping floor is severe enough that you simply can’t ignore it, fixing it should be a priority.

Sloping and sagging floors caused by foundation problems aren’t an easy fix, but finding a company to do the work shouldn’t be too difficult. Foundation specialists will repair any structural problems first, then use one of a few different techniques to mend your sloping floor. This might involve jacking up floor joists and installing supports, or it could require jacking up the whole house and installing new footers. When done right, jacking up a house takes a long time. Plan on several weeks if you want to avoid structural damage.

If your sloping floor is caused by improper installation of the floor itself, you may be able to simply get the floor pulled up and installed again the right way or put down an entirely different floor. In some cases, you might have to install a new sub-floor or create a new moisture seal. Especially in older homes where the support system under the floor might be deteriorating or simply not that strong in the first place, additional support might need to be put in place to handle the weight of some flooring materials.

In most cases, fixing sloping floors is involved enough that you probably won’t be able to get an estimate over the phone. It’s worth the time, however, to meet with and get estimates from several contractors to find both the best price and the company with the most experience doing this kind of work.
