Why Encapsulation Matters in New London
The Midwest is the highest-radon region in the country. Encapsulation here is most effective when paired with active radon mitigation — the same vapor barrier that blocks moisture also blocks soil gas. Bundling encapsulation with radon mitigation typically saves $500–$1,200 vs separate installations.
What a New London Encapsulation System Should Include
- ✓12–20 mil vapor barrier with sealed seams (radon-rated)
- ✓Active radon mitigation system (sub-membrane depressurization)
- ✓Sump pump and interior drainage (heavy clay soils retain water)
- ✓Wall insulation R-10 to R-15
- ✓Dehumidifier sized 70–90 pints/day
- ✓Reinforced barrier in flood-prone areas
What to Watch For in Wisconsin
- !Test radon BEFORE encapsulation. If levels are high, design the system for radon mitigation from day one — retrofitting is expensive
- !Demand a barrier with sealed seams, not just overlapped — radon migrates through gaps
- !Confirm the contractor is licensed for both encapsulation AND radon mitigation (different licenses in many states)

How much does crawl space encapsulation cost in New London, Wisconsin?
Crawl space encapsulation in New London, Wisconsin typically costs $3,000–$8,000 for a complete system. Pricing depends on crawl space size, vapor barrier mil thickness (12-mil to 20-mil), whether a dehumidifier is included, and wall insulation specs. Midwest — Radon + Moisture pricing reflects local labor rates and climate-driven scope.
What vapor barrier thickness is best for New London?
20-mil radon-rated is recommended if you are mitigating radon. For moisture-only projects, 12-mil is sufficient. Always specify "radon-rated" if radon levels are >2 pCi/L.
Do I need a dehumidifier with encapsulation in New London?
A 70–90 pint/day unit covers most Midwest crawl spaces. Pair with the radon fan — they handle different problems but share the same sealed envelope.
How long does crawl space encapsulation last?
A professional encapsulation system in New London lasts 15–25 years. The vapor barrier itself (especially 20-mil reinforced products) can last 25+ years. Dehumidifiers should be serviced annually and replaced every 8–12 years. Most contractors offer transferable warranties of 10–25 years on the vapor barrier and 5–7 years on the dehumidifier.
When is the best time of year to encapsulate a crawl space in New London?
Late summer through fall (August–October). Avoid spring — flooding makes crawl space access unsafe and wet substrate prevents proper barrier adhesion.
Expected ROI
Radon reduction alone is a health benefit, not a financial one — but it is required disclosure on real estate transactions in most Midwest states. Encapsulation + radon mitigation together typically add $8K–$18K to home value vs unmitigated.
Best Season to Schedule
Late summer through fall (August–October). Avoid spring — flooding makes crawl space access unsafe and wet substrate prevents proper barrier adhesion.
