Crawlspace Structural Support – Centennial

A sagging main beam in a Centennial crawlspace, corrected with a new caisson footing and steel posts.

The homeowners noticed the floor above the crawlspace was dipping. When we went underneath, the main beam was sitting on undersized gray adjustable posts set on old piers, the kind of temporary fix that was never meant to carry a house long-term. We dug out to check the existing footing depth, then poured a new caisson footing and set new steel posts bolted to base plates under the beam. With the beam properly supported, the floor was brought back to level and the vapor barrier was put back in place.

Structural work like this isn’t glamorous, but it’s the kind of problem that gets worse and more expensive the longer it’s ignored. It also comes up constantly on home inspections, so if you’re planning to sell, fixing it before you list keeps it from becoming a negotiating point. Floors and stairs were protected before the crew started, and the homeowners were back to normal use the same week.

If you’ve got a soft spot in the floor or an inspection report that mentions the crawlspace, we’ll take a look and give you a written, itemized estimate.
