Crawl Space Encapsulation

  • Full vapor barrier system to seal crawl space floors and walls
  • Vents and air leaks sealed to block external humidity

Local Highlight:

We encapsulated a home in Oak Terrace Preserve where elevated humidity had caused HVAC strain and visible mold. After sealing, the difference in comfort and air quality was immediate.

Neighborhoods with older construction — like Park Circle — often deal with long-term moisture damage beneath the surface. We fix it cleanly and professionally.

Crawl Space Insulation

Drainage & Sump Systems

Local Highlight:

After repeated crawl space flooding in a Dorchester Terrace home, we installed an internal French drain and sump pump combo — the crawl space has remained dry since.
