Frequently Asked Questions

The support beams and floor joists in your crawl space are designed to support the weight of your home. The floor joists have to be precisely spaced otherwise you’ll have a sagging floor or uneven floors. And if the floor joists aren’t supported properly then your floor will eventually cave in, creating even bigger problems – which can stem from:E


Is your crawl space sealed or do you have open vents? An unsealed crawl space allows moisture – which produces mold. Mold thrives on organic (any living material – like trees – or wood) material, which causes wood rot, decay, and structural damage.E

Weight of Your Home

Before you start a home improvement project, it’s important to think about the floor support. When you add more weight to the floor, like new granite counter tops, the floor joists may require additional support to safely hold your floor up.E

Poor Support Design

The support columns and floor joists are designed to hold up the weight of your home. When the floor joists are over spanned –the support columns aren’t spaced properly so there isn’t enough of support under the floor joists – your home will have sagging floors, a gap between the wall and floor, and even squeaky floors.

Fixing sagging floor joists is a job best left to the professionals. If an over spanned or sagging floor joist is supported incorrectly or your home is lifted up too quickly, additional problems can be created: uneven floorsdrywall cracksgaps between the floor and wall, and stuck windows.
