Crawl space encapsulation in Dallas.
Vapor barrier encapsulation and dehumidification for Dallas pier and beam homes. Stop the seasonal mold cycle under your floor instead of treating it every two years.
From $4,800 · 25-year warranty on the vapor barrier, 1-year humidity guarantee under 60% RH.
The problem
Your pier and beam home smells musty every summer, the floors feel damp, and the crawl space has fuzzy joists nobody wants to look at.
Up to half the air on your first floor rises from the crawl space. Open vents pull in humid Texas air all summer, it condenses on cool framing, and mold eats the joists year after year. Treating the mold without fixing the moisture is a subscription, not a solution.
We remediate any existing growth, then seal the ground and walls with a reinforced 20-mil vapor barrier, close the vents, and install a commercial dehumidifier with a humidity readout you can check from the hallway. The moisture cycle stops, the musty smell goes with it, and your HVAC works less.
We handle every crawl space encapsulation job from start to finish. Our crew always shows up on time, works clean, and we stand behind every result.

Recent crawl space encapsulation reviews
Our 1962 house near downtown Garland smelled musty every single summer. They treated the joists and encapsulated the crawl space, and this is the first July the house has smelled normal. The humidity readout says 52% down there. Used to be a swamp.
Water heater failed in our South Garland rental and the tenants did not notice for two days. Crew was there within the hour, dried it out, and the testing confirmed no mold took hold. They sent daily moisture readings, which my insurance adjuster actually complimented.
Every big storm left water standing against the back of our Rosemeade house, and eventually mold showed up inside the wall of the den. They removed the affected drywall, treated the framing, and told us plainly that grading the yard was the real fix. No upsell, just honest scope.
Musty smell in our Furneaux Creek area home that two AC companies could not explain. Their air test found elevated counts in one bedroom, traced to moisture wicking through the slab edge. Remediation passed lab clearance and the follow-up test six months later was clean too.

Frequently asked questions
Is encapsulation worth it for an older Dallas home?
Pier and beam homes are exactly where it pays off. Most were built with open vents on the theory that airflow dries the space, but in Texas humidity the vents do the opposite. Owners typically notice the musty smell gone within two weeks and lower summer cooling bills the first season.
What about my foundation vents? I heard crawl spaces need to breathe.
That advice fits dry climates, not North Texas. Here, summer vent air arrives at 70%+ humidity and condenses on framing that the AC has cooled from above. Sealed and dehumidified beats vented in our climate, and the joist moisture readings prove it on every job.
Will this help with sloping floors?
Encapsulation stops the moisture that rots joists and beams, which prevents future sagging. It does not jack up framing that has already dropped. If we find structural damage during inspection, we photograph it and refer a foundation contractor before we seal anything.
