The Happy Crawl Space Encapsulation Package

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 and prepare the space for a flawless encapsulation.

Our lifetime warranty is unrivaled. If anything fails, we fix it. No questions, no hassles.

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.

Happy Crawl Space is a service of CNT Foundations — a family-owned foundation and crawl space specialist with 25+ years of experience, 10,000+ projects completed, A+ BBB rating, and a 4.5★ / 481+ Google rating.

Justin was exceptionally efficient, focused, and customer oriented. He was very kind and thoughtful regarding how to solve my concern around the door sticking and foundation sinking. Thank you Justin!!

Justin and his team did a great job lifting and stabilizing my home, which had been built with a woefully inadequate foundation (beams 14' on center). So they had to put in 3 more beams plus the vertical piers under them. All work was done on time, within the quoted amount and the premises were left entirely clean. Very happy!

I found Justin Leboeuf and his crew outstanding. Very conscientious and hard working. They paid great attention to detail and were very easy to work with. They did a fantastic job.Dr. Bagshaw, Edgefield Veterinary ClinicJustin was beyond amazing throughout our project. He and his crew were pleasant, had a wonderful work ethic and worked very hard to complete our project on time (and they did). Justin answered all of our questions and concerns as we checked on the project status. Justin went out of his way to assure we were happy with the work being done....the work was done correctly. Justin documented with pictures and sent them to us. They cleaned up behind themselves as they went. This team, being led by Justin, did a remarkable job and we look forward to having them return to complete Phase 2 of our project.Barbie Yonce, Edgefield Veterinary Clinic

We used CNT Foundations to lift our raised backyard patio that had sunken in due to drainage issues under the patio over the years. There was a large crack in the concrete across the middle of the patio and another crack running from the middle of the center crack to the outside edge of the patio. We were given a reasonable estimate up front for the work and the job was scheduled in a timely manner. The technician, Jeremy, arrived on the morning of the job and was candid about what they could do in a situation like ours. He was able to level the patio with PilyLift foam and sealed the cracks in the concrete to finish the job. It has taken us some time in getting used to stepping up on the level surface. We initially attempted to get another foundation specialist that we had used in the past to do the work, and they said they couldn't do the job and would not give us an estimate. We are very pleased with the job done by CNT Foundations.

We had an industrial site repair that needed taken care of. Dan was our sales rep at CNT’s Greenville SC location. He was very thorough, explained the process, what we needed and got us a quote very quickly. Jeremy, our onsite technician, did a fantastic job. Both were on time and professional. Jeremy completed the process in a very timely manner despite the added hassle of a ton of water being found under the concrete. We were very pleased with both Dan and Jeremy and will definitely use CNT Foundations again.

Dan was exceptional! He set the bar for any contractor. He was so pleasant to work with, punctual, and completely trustworthy. He is a commission based representative and told me that we don’t need any of his services. He recommended a dehumidifier and that was it. We had two other companies come in and tell us we needed upwards of $10k worth of work. His honesty was incredibly admirable and now if I ever have a foundation/water concern, I won’t even consider going with any other company.

Eddie came out for the initial inspection and determined the cause of our uneven floors was degraded shims. Two other foundation companies wanted to install expensive and unnecessary CMUs. We went with Eddie’s quote and because we were saving so much money, we decided to have CNT do a full encapsulation in our crawl space. Our floors are even now, and our crawl space is secure, and we saved money. Highly recommend CNT Foundations!

I contacted CNT regarding an issue with water damage within my garage. CNT was very responsive and scheduled an appointment. They clearly communicated leading up to the visit. Dan from CNT was very knowledgeable and reviewed the issue and possible causes. I appreciate how the information was presented and that an expensive diagnostic procedure was determined not to be needed. Dan also suggested alternate approaches to keep the environment free from issue. I would definitely use CNT if I encounter any such issues again.
