What Are Floor Joists?

Floor joists are horizontal beams that run beneath your floors, usually supported by foundation walls, beams, or posts. Over time, they can weaken due to:

• Moisture and humidity

• Wood rot or mold

• Poor original construction

• Soil movement under supports

• Insect damage

When joists fail, floors sag, bounce, or slope — and the longer it goes untreated, the more expensive repairs become.

Signs You Need Floor Joist Repair

You may need floor joist repair if you notice:

• Uneven or sloping floors

• Bouncy or springy areas when walking

• Cracks in walls near floor lines

• Gaps between floor and baseboards

• Doors that stick or won’t close properly

These signs often appear gradually, which is why many homeowners don’t realize there’s a structural problem until it’s advanced.

How Floor Joist Repair Works

Depending on the cause, repairs may include:

• Sistering new joists alongside damaged ones

• Installing steel or wood support beams

• Adding new support posts or piers

• Reinforcing crawl space or basement framing

• Correcting moisture problems that caused rot

Every home is different, so repairs are always custom-designed.

Why Moisture Is Often the Real Problem

In Maine, floor joist problems are frequently caused by moisture:

• Damp crawl spaces

• Poor ventilation

• Basement leaks

• High humidity

That’s why we often combine joist repair with:

• Crawl space encapsulation

• Basement waterproofing

• Dehumidification systems

Fixing the structure without fixing the moisture just guarantees the problem will come back.
