Our crawl space had a musty smell for as long as we've owned the house. The team removed the mold that was there and encapsulated the whole space, and they were careful to work around our radon vent pipe the whole time.

Reviews
Rated 5 by Lansdowne-area neighbors
Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.
The mold cleanup itself was great. The only hiccup was a reschedule due to weather.

Local knowledge
Crawl Space Encapsulation for Lansdowne, PA homes
Crawl Space Encapsulation in Lansdowne tends to start the same way mold does across Delaware County: older Lansdowne homes with finished basements and low ventilation that let damp air linger. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from East Lansdowne, Yeadon, Drexel Hill and the rest of Lansdowne call us.
We handle crawl space encapsulation for Lansdowne the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.
Our team is based in Narberth, about 10 minutes from our Narberth base, so we can usually reach a Lansdowne home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.
Lansdowne specifics
What Crawl Space Encapsulation in Lansdowne really involves
Older and newer homes alike need Crawl Space Encapsulation, from the newer builds near Clifton Heights to the oldest ones in town. When people here search for Crawl Space Encapsulation, the growth they can see is usually the last symptom, not the cause. By the time a family calls us for Crawl Space Encapsulation, they have usually already seen a musty smell or a spreading stain. If you have noticed a musty smell or a spreading stain in your home, crawl space encapsulation is worth a call before the damp reaches the framing.
Our crew has done Crawl Space Encapsulation across Delaware County enough to know how plumbing leaks and poor ventilation moves through these homes. The reason Crawl Space Encapsulation comes up so often here is simple: heavy rain and seasonal flooding pushing water toward foundations and crawl spaces, working on local homes month after month. We handle Crawl Space Encapsulation for homes from Clifton Heights to East Lansdowne and the surrounding area the same careful way. For a home in this area, crawl space encapsulation starts with finding the moisture, because the water is what feeds the mold.
Here is how Crawl Space Encapsulation usually goes:
- HEPA vacuum, clean, and treat the surrounding surfaces
- Stop the water source so the problem does not come back
- Dry the structure with commercial equipment until readings normalize
- Recheck the space and document the work for your records
- Inspect the affected area and find the moisture feeding the mold
Since we are only about 10 minutes from our Narberth base, a call for Crawl Space Encapsulation rarely waits long.
Good to know
Crawl Space Encapsulation in Lansdowne, PA: common questions
Do you remove existing mold before encapsulating?
Yes, encapsulating over active mold growth doesn't solve the problem. We remove and treat existing mold first, then install the vapor barrier.
How long does crawl space encapsulation take?
It depends on the size of the crawl space and how much remediation is needed first, but most projects are completed within a few days.
Is my crawl space a good candidate for encapsulation?
Dirt crawl spaces with recurring moisture, musty odors, or visible mold on framing are typically good candidates. We can assess yours during an inspection.
How do you keep the mold from coming back after crawl space encapsulation?
We fix the moisture source first, not just the mold, then dry the structure and recheck it. That is what keeps mold from returning to a Lansdowne home.
Will encapsulation affect my radon mitigation system?
No, we coordinate the vapor barrier installation carefully around existing radon vent piping so the system continues working as intended.
Does encapsulation stop mold from coming back?
It significantly reduces the ground moisture that feeds mold growth, which is the main reason crawl spaces develop recurring problems.
Do I need to leave my Lansdowne home during the work?
Usually no. We seal the work area under negative air, so most of the Lansdowne home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Lansdowne?
Yes. We cover all of Lansdowne, including East Lansdowne, Yeadon, Drexel Hill, and the rest of the Lansdowne area. We are based in Narberth, about 10 minutes from our Narberth base, and answer our own phone around the clock.
