How To Fix Sagging Floors

So, you're sick and tired of your sagging floors. And you're looking for a way to fix them. Before you try to fix your floors as a DIY project, there are a few things you need to know.

Sagging floors are typically a sign of structural problem. They can be caused by poor floor support design, settlement or moisture problems.

Poor Floor Support Design

If your sagging floors are caused by poor design then you may need to install a new support structures, like the SmartJack™ floor joist jacks.

Sagging Floor RepairInstalling jacks is a precise process. Each jack has to be appropriately placed, taking into account bearing capacity and location. If the jack is raised too quickly, it could end up damaging your home.

The remedy could also be as simple as sistering the joists. However keep an eye out for other structural problems. For example, if the joists are wet or rotted through, sistering them will not be enough to secure your floors.


If your sagging floors are caused by settlement then the repair may involve more than installing jacks. Depending on the severity of the foundation settlement, your home may require push piers to stabilize the foundation and restore safety. And this is a job that should always be left to the experts.

"I was extremely happy with all those on the work crew for the work they performed and their professionalism. They worked continuously until dark, sometimes working until after 7:30 pm. Their finished product is impressive and they left my wife and I so glad that we selected your company. Best of all, my wife who is highly allergic to mold and mildew, has been able to breathe better than she has since we bought the house, so this is great!"
