Sinking & Sagging Floors Over Your Crawl Space

The terms are often used interchangeably, but they can describe different types of movement. A floor may sag when joists or beams bend or lose support, while sinking can occur when columns, footings or the soil beneath them settle. An inspection can determine which part of the floor system is actually moving. 

Sagging floors don’t necessarily mean walking away from a home, but they do warrant a closer look. Before buying, have the cause and extent of the problem evaluated. Understanding whether the home needs added structural support, floor joist repair, moisture control or more extensive work can help you make an informed decision. 

The cost of sagging floor repair depends on the cause, extent of damage and repairs needed. Adding crawl space support jacks may cost something different than repairing rotted floor joists or addressing moisture problems. Blackburn Foundation Repair offers free inspections in [Target Location] to identify the problem and provide recommended solutions and pricing. 

The timeline comes down to what’s causing the sagging and how much repair is needed. Installing structural supports like the SmartJack® system may take less time than a job involving extensive wood or subfloor repair, moisture control or multiple problem areas. After inspecting your crawl space, Blackburn Foundation Repair can review the recommended repairs and expected timeline. 

In some cases, crawl space support jacks can gradually lift sagging beams and floor joists toward a more level position while providing permanent support. How much correction is possible depends on the cause, severity and condition of the floor system. An inspection can determine whether lifting and floor leveling are appropriate for your home. 

Yes, sagging floors can often be fixed without replacing the whole floor. If the flooring and subfloor are still in good condition, the repair may focus on the structure underneath. Depending on the cause, that could include adding crawl space support jacks or repairing damaged joists and beams. Heavier wood rot or damage may require some wood, subfloor or flooring replacement. 

Sagging floors aren’t always just a cosmetic issue. They can signal weakened floor joists, settling supports, wood rot or other problems with the structure beneath your floor. Even if the sag appears minor, it’s worth having the crawl space inspected to pinpoint the cause and whether structural repair is needed. 

Sagging floors can be caused by excess moisture in the crawl space, wood rot, inadequate support, settling support columns or footings or termite and pest damage. Sometimes, more than one problem is involved. A crawl space inspection can determine what’s going on beneath the floor and what type of structural or moisture-control repair is needed.
