Crawl Space Drainage
Perimeter drain tile below the vapor barrier, pitched to a sump. This goes in before the liner — retrofitting drainage under a finished encapsulation means pulling it up.

What makes a Leland crawl space different
Leland's growth is recent and it shows in the crawl spaces. Large parts of Brunswick Forest, Magnolia Greens and Compass Pointe went up in the last twenty years on land that was low, flat and in places wetland before it was subdivided. The houses are modern and well built; the ground underneath them is the issue.
That produces a different problem from Wilmington's older stock. These are not decayed pier foundations — they are relatively new crawl spaces with a builder-grade 6 mil sheet laid loose on the floor and open foundation vents, sitting over soil with a water table close to the surface. The construction is sound and the moisture strategy was never adequate for the site.
The practical consequence is that Leland crawl spaces often need drainage more than they need remediation. Where a Wilmington downtown home might present with decayed framing after decades, a ten-year-old Leland home more often presents with standing water after heavy rain and a liner that was never going to cope. Getting the water intercepted is usually the whole job, and the liner replacement follows it.
Crawl space services in Leland
The work most often needed on Leland properties, in the order it usually has to happen.
Crawl Space Waterproofing
Most requestedStopping water getting in, before anything gets sealed. Grading, downspout extensions, perimeter drainage and a sump where the water table demands it.
Waterproofing detailsCrawl Space Sump Pump Installation
A sealed basin, a pump rated for the volume, a check valve and a discharge line that carries water away from the foundation rather than back to it.
Sump Pump details
Crawl Space Encapsulation
Most requestedA sealed liner across the floor, piers and walls, taped and mechanically fastened, with the vents closed and the space dried. It is the full system, not a sheet of plastic laid on dirt.

| Vent sealing | $300 – $1,000 |
| Dehumidifier (installed) | $1,200 – $2,500 |

What moves the price: crawl space square footage, working clearance, whether groundwater has to be dealt with first, and how much of the framing needs treatment.
Leland crawl space questions
- Why do so many Leland crawl spaces have standing water?
- Much of the recent development sits on low, flat ground with a high water table, some of it former wetland. The houses are new but the site conditions are wet, and a builder-grade 6 mil liner over open vents does nothing about groundwater rising into the space.
- Is my Brunswick Forest home too new to have crawl space problems?
- Age is not the protection people assume. New construction gets a builder-grade vapor barrier and open vents, which on a high-water-table site is insufficient from day one. We see ten-year-old Leland crawl spaces in worse shape than fifty-year-old Wilmington ones.
- What does crawl space work cost in Leland?
- The same $4,200–$14,000 range as the wider Wilmington area, but Leland projects skew toward the upper half because drainage is more often required. A perimeter drain and sump adds $1,500–$5,000 to a liner-only scope.
- Do I need a permit in Brunswick County?
- Encapsulation itself is generally treated as repair, but electrical work for a dehumidifier is permitted work, and structural repair certainly is. We confirm scope with Brunswick County before starting rather than after.
- Will the builder's warranty cover crawl space moisture?
- Usually not. Builder warranties typically cover defects in workmanship for a limited period, and a code-compliant 6 mil liner over open vents is not a defect — it is just inadequate for the site. Check your specific warranty documents.
