Subfloor Repair in Old City

The subfloor is the surface every floor depends on — and in Florida it fails from moisture, termites, and flooding. We repair both slab and wood decks, but never before testing moisture and mitigating vapor, because a new floor over a wet or weak subfloor fails through the surface.
