The Happy Crawl Space Encapsulation Packages
What's Included:
We install a thick, puncture-resistant polyethylene vapor barrier across the entire crawl space floor and foundation walls. This creates an impenetrable shield against ground moisture.
Open vents invite humid outside air into your home. We seal every foundation vent and air leak with a rigid foam board, stopping condensation before it starts.
All seams, overlaps, and edges are tightly sealed using specialized heavy-duty waterproof tape to create an airtight barrier.
South Carolina humidity requires active management. We install high-capacity crawl space dehumidifiers to maintain optimal moisture levels year-round.
Custom vent covers provide a permanent seal against the elements. We secure every opening to ensure your crawl space remains a controlled environment.
Every project begins with a thorough inspection and the removal of debris. We clear out old insulation and prepare the space for a flawless encapsulation.

Questions Worth Asking
We removed the highest costs in the industry: door-to-door sales commissions, multi-step lead generation, and pricing-for-the-room negotiation. The materials and crew are the same — actually better, since we standardize on premium WallSeal™ liner. We make our business work on volume and operational simplicity, not on getting one customer to overpay.
South Carolina law requires every encapsulated crawl space to include a dehumidifier. Quotes from competitors that don’t include one aren’t code-compliant — and they’ll typically add it back later as a $1,500–$2,500 surprise. We don’t play that game. Every Happy Crawl Space package is fully code-compliant from the start and includes everything you need.
That’s what the confirmation at installation is for. If we find mold, structural sag, water intrusion source repairs, or anything outside the standard scope, we tell you in writing before any work starts. You can walk away with a full $500 refund. About 95% of homes fit the standard scope as-is.
Yes — fully refundable up to 7 days before your install date, no questions asked. Inside 7 days, it’s refundable for any reason we discover at the time of installation (e.g., scope change).
One to two days for most homes. We’ll give you a specific timeline when we call to schedule the work. You don’t need to be home during the install — we work in the crawl space, not in your house. Crew typically arrives between 8–9 AM.
Yes — we offer flexible monthly payment options for qualified buyers. Financing details will be presented after you reserve, at your request.
We serve South Carolina, and parts of North Carolina, Georgia, and Florida. Enter your install address during reservation — if we don’t serve your area, we won’t charge the deposit and we’ll happily recommend someone who does.
