Subfloor Replacement Services in Orlando, Florida
Subfloor replacement is essential when water intrusion, termite damage, or dry rot compromises the structural integrity beneath your home's main floor. In Orlando's humid subtropical climate, subfloors in older homes around Lake Eustis, Mount Dora, and even newer subdivisions in Winter Springs and Sanford are vulnerable to moisture penetration. Bill Morgan Inc removes damaged sections, treats remaining wood with fungicide if needed, installs new pressure-treated lumber or engineered I-joists, and applies moisture barriers to prevent future problems.
Our subfloor replacement process begins with a thorough inspection to identify the extent of damage-whether isolated rot near the kitchen or widespread mold affecting 20-40% of the subfloor. We temporarily support the floor joists using adjustable posts, remove damaged decking and rim board, treat the foundation or crawl space for moisture control, install new pressure-treated 2x10 or 2x12 lumber or engineered joists rated for Florida's load requirements, seal all new wood with polyurethane or deck sealant, and reinstall or upgrade the subfloor decking with tongue-and-groove plywood rated for moisture resistance.

Our Subfloor Replacement Process
Inspection and Damage Assessment
We inspect your crawl space or basement, test moisture levels with a meter, and document all damaged areas. This takes 30-60 minutes and determines whether isolation repair or full subfloor replacement is needed.
Temporary Floor Support Installation
We install adjustable support posts and temporary beams to support the floor structure safely while subfloor sections are removed. This critical step takes 2-4 hours depending on damage extent.
Removal of Damaged Materials
We carefully remove rotted joists, decking, and rim board, then haul away debris. Removal typically takes 4-8 hours for moderate damage affecting 100-200 square feet.
Moisture Control Treatment
We apply fungicide to remaining wood and install polyethylene vapor barrier across the crawl space floor to block future moisture. This preventive step adds 2-3 hours.
Installation of New Subfloor Structure
We install pressure-treated 2x10 or 2x12 joists (or engineered I-joists) spaced 16 inches on center, then install new 3/4-inch tongue-and-groove plywood decking. This phase takes 6-12 hours depending on square footage.
Final Inspection and Cleanup
We remove temporary supports once new structure is cured, inspect all connections, test floor stability, and perform complete site cleanup. Final walkthrough and inspection takes 1-2 hours.
