Crawl Spaces
Crawl Space Repair
Your home is a complex system of interdependent parts — when your crawl space shows signs of rot, mold, or structural damage, those problems don't stay put. They spread to the rest of the house.
A dry crawl space is the starting point of a healthy home. The walls enclosing your crawl space are part of your home's foundation — the base your entire house stands on. Prolonged wet, damp conditions can compromise those foundation walls and cause structural damage, and moisture can buckle hardwood floors above, adding safety hazards on top of the cosmetic damage.
Common Crawl Space Problems We Fix
- Sinking crawl space supports — support pillars built on soil that can't bear the weight of your home will sink over time, taking the floor above with them and leading to uneven floors and interior wall cracking.
- Inadequate structural design — support beams spaced too far apart during original construction let the floor sag in the spans between supports.
- Rotting floor joists — damp, humid, or flooded crawl spaces are ideal conditions for mold, rot, and wood-eating insects like termites and carpenter ants, all of which weaken the joists that hold your home up.
- Foundation wall failure — most often from settling caused by poor supporting soil, or from walls buckling inward under pressure from expansive soils outside the home.
Crawl Space Repair Services
- Support jacks — a fast, permanent, warranted solution for foundation and settling issues under your home.
- Sister joists — adding a matched board alongside a damaged joist to restore strength and stop sagging or flexing floors.
- Mold removal — fungus and mold growing on floor joists release spores that pollute the air quality throughout your home, so remediation is often part of a full crawl space repair.
We start every job with a detailed inspection, take pictures of what we find, and lay out a repair plan — often with good, better, and best options so you can choose what fits your home and budget.
Frequently Asked Questions
Signs like sagging or uneven floors, cracking interior walls, sticking doors, or visible rot and mold on the joists point to a structural issue, not just a moisture nuisance. An inspection can tell you which supports or joists are affected and whether the foundation walls themselves are involved.

“Rob and his crew are super. I had a very big project to renovate a 130-year old farmhouse. They worked diligently to put in new piers, new girders, and new joists. Then they also help to fix some frames and add subfloor. This allowed me to move on. Really enjoyed working with Rob.”

“Very professional! They carried out their task while going the extra mile. It was obvious to me that quality is of great importance. They left it better than they found it. I would recommend them to my greatest of friends and family.”

“After having some minor flooding issues, we contacted Triangle Reconstruction and they were amazing in their ability to identify the issues and the best way to address it. What was most impressive was the team that came out and did the work. They were probably the most professional and organized crew we've ever seen work on our house. Brian, our rep, and Rob, the owner, regularly checked in on their work and kept us updated on the progress. I hope I never have to deal with flooding issues again, but if I do, I'll call Triangle Reconstruction again.”
