This place is fantastic. I was able to visit locally and spent a good amount of time asking questions and getting solid answers. HB stayed after closing to make sure my plan was correct and I had the knowledge needed to make it a success. We even discussed new ideas. This is a company interested in driving the industry vs just selling a product. Very cool to see items in progress. Thank you for sharing. Well, I'm almost finished and my knees and back, and elbows cant wait for some relief. 3300sqft, almost 40 piers, 16 rolls of seam tape, 4 rolls of 15mil plastic, 5 rolls of wall curtain, 2 AprilAire dehumidifiers, and a box full of adhesive. I used one of their references for mold mitigation who saved my money and did an excellent job. My crawlspace is unbelievably clean now. Thank you so much for all your help and this extends to the office crew. Great Team.

Just finished my 2000 square foot crawl space encapsulation project. Worked on this by myself over the course of a couple months. Crawlspace is only 36 inches tall so I couldn't be down there for extended periods of time. Worked with HB and Benny and they got me the perfect set-up. Used the crawl curtain with the magic sealant and it worked beautifully. Did not want to put holes in my block foundation so that's why I chose this method. Also elected to use the 36 mil felt backed vinyl sheeting and it was great. Plenty of choices out there but I feel like this was clearly the least complicated and the best for me. Saved myself over 8k doing this myself. John East Tennessee resident

Thank you so much for your support of Hope's House in Summerville, we no longer have to worry abut moisture issues, you are a blessing!

We purchased Your Crawlspace products for an old house that had probably never seen a vapor barrier, to be installed by DIYers who had never installed one. We installed the wall curtain and 9mil VB, and used the Magic Sealant/Adhesive and seam tape designed for the curtain and VB. It might be easy to understate how pleased we are with our purchase, the ease of installation and the results. We would definitely recommend the Your Crawl Space product line and their Customer Service reps. While I would prefer to not have to install a vapor barrier again, if the need should again arise, I would I would go straight back to YCS. Really, very pleased Rick Green Bellingham, WA

This company is a excellent company to have as a business partner. We have been using them a little over the past year and they have always gone above and beyond on helping us with orders that we need to do our jobs. They are more like friends than a vendor! Give them a call, you wont be disappointed.

About ten years ago, I bought their vapor barrier to seal off a crawlspace floor. It came with all the adhesive and tape and so on needed to handle the job. When I was done, it was a huge upgrade and, to my surprise, it held up to years of walking on it (fairly slippery though, best to cover with something). I think I put one or two holes in it from dropping a sharp tool (the crawlspace is my storage/tool area). A couple of years ago, we had a flood and I had to cut the membrane up and install a sump pump and do other remediation. I finally have gotten around to ordering their newest product - similar to the membrane I had, but with a felt backing. I'm looking forward to many years of service on this one. Hopefully I won't have to destroy it with a razor knife again. Great product, great service, nice folks. I couldn't be happier.

My company, Green Home Solutions of Mid-Coast Maine, has had the opportunity to install several basement and crawlspace encapsulations with the YCS system and materials. This is top-quality stuff and I love that we don't drill holes in cellar walls any more. Thank you for excellent customer service, too!

This is an amazing company! A few months ago my hardwood floors started to cup and buckle in some areas. I was advised by a local company that I needed to encapsulate - that the moisture was simply atmospheric and only encapsulation would solve the issue. The quote from the local company for the materials and installation came back over 8k. I contacted Your Crawlspace Vapor Barrier Systems and spoke to HB. He was incredibly helpful. The total for the materials came up to $1,800.00. I was very pleased!

After exploring options and products, I landed with YourCrawlspace because of the quality of the material and ease of installing the wall curtain without any fasteners penetrating the wall. HB was always available and a big help for this project. Very pleased with outcome.

They were just amazing. The sales rep HV walked me through everything I needed step by step it was great. I was quoted 10k to do my massive crawl with dehumidifier. In the end I had about 1500 in mine and it just looks great. I had a few hiccups with my material and they took care of me and rushed me what I needed to make me happy! Just 5 stars. Material and videos make it very easy to do it yourself!

When I decided to encapsulate my crawlspace myself, it was difficult to decide what products to choose. Bennie and HB at Your Crawlspace made it really easy to choose once they explained their wall system and adhesive over the phone. the pre-cut wall system and adhesive saves on time and truly creates an unmatched seal to keep out unwanted moisture. Not to mention that they had what seems like the best floor barriers. It would have cost me $10K+ to have a contractor complete the work. I did it myself for less than $2K and I couldn't be happier with the results.

Excellent product and customer service. From the start the communication was excellent products where delivered quick .They followed up to see how the project was progressing (who does that anymore? :) The product is of top quality and perform perfectly . Humidly is below 50% (in Durham, NC) in the crawl . The heat cycles a lot less and has been able to maintain 70 F even on 15 f mornings in our double wide with a heat pump. If your looking to seal your crawlspace you found the source for your material Andy

I encapsulated my own crawlspace. It was a big job. Took me quite a while, but I'm very happy with the results. I used the heavy duty drain mat on both the walls and floor. I used the special adhesive caulk and the seam tape just as Bennie instructed. I'm impressed with the materials. They were of very high quality. I also appreciated the help YCI gave me over the phone prior to ordering and doing the job. They were patient and very helpful. Without hesitation, I would highly recommend them to anyone thinking of doing this on their own.

My crawlspace installation has just been completed and I couldn't be happier with the results. The crawlspace is completely sealed and it looks great. The humidity is already down in the crawlspace and the house. YCS products are awesome. The install is clean and complete with no holes in my foundation. The wall curtain system is simple but ingenious! If I had used the "christmas tree" plug method or a Hilti gun approach to attach the wall curtain from other vendors there would be over 500 holes in my foundation and piers. Not sure how you feel about that but I don't like holes in my foundation. This instillation method is superior to everything else on the market and provides the most completely sealed system you can get. It also is the fastest installation method. Don't bother looking elsewhere. Just call Bennie or HB and get on with it. The Aprilaire 1820 humidifier I purchased is really nice and much more functional and advanced than the Santa Fe Compact 2 I was going to buy. I bough the Aprilaire from YCS as well. I am so glad I did. Three big differences I see: 1) The Aprilaire has a digital control system with readout. The SantaFe has an analog dial with no readout. 2) The Aprilaire has a filter that can be cleaned. The SantaFe has to have the filter replaced every six months. 3) The Aprilaire has a ventilation function that will circulate the air for a user set time in minutes per hour. The SantaFe can only have the fan on full time or on Auto.

Bought a whole system with a Aprilaire 1820 dehumidifier. HB gave me lots of tips and was very helpful. Total cost was around $1800 for all of the materials and dehumidifier. Saved a boatload of money. My son and I did the whole thing over a weekend. Humidity was over 90% before and now is down to to 50%. Quality materials. I would recommend them to anyone wanting to do this themselves.

After watching the instructional videos I called to order the supplies I needed to install the vapor barrier. I was pleasantly surprised that when I called I Benny himself answered! He helped walk me through the products and quantities I needed, the product was shipped same day and exactly the right amount of product I needed was delivered. The adhesive with the tape attached does need one day to cure before applying the wall curtain. The adhesive is SUPER strong, the vapor barrier was easy to roll out. We were applying over dirt, rock and gravel and the vapor barrier did not puncture. The space transformed from dark,dirty and unusable to bright, white, clean and usable. Thanks for all your help, Bennie! Very professional and was there to take my follow up calls also! I tried to post more photos but it would only allow me to upload 3.

I decided to go diy to seal up my crawl space. I already had a 16mil vapor barrier on the floor. I used the wall curtain/adhesive and the install went really well. It is much faster than the old way with foundation pins and butyl tape. I didnt even clean the walls. Apply the adhesive with a caulk gun and press the wall curtain into it. The next day I went back and taped up all my seams. Shipping was fast and the product worked great. Great company.

I found the products provided by your crawlspace after 3 months of research and prep to replace my crawlspace vapor barrier. Mostly that was a debate with myself on encapsulated or not. Primarily I have been on a 2 year tear with my crawlspace after smelling a musty odor in the home and finding a lake under my home. The first thing I did was build an external french drain around the home. This mitigated 80% of the issue the next year but I did still have water. So... This year I trenched another french drain inside my crawlspace. But I was still concerned about water so I wanted a water tight vapor barrier system. Yes, here is finally the part you care about. Specs: 1. 18" crawlspace - I'm 6'4" so this is VERY challenging to work in. It's also a good workout. Just got to adjust your perception. 2. 1090 sq ft of crawlspace 3. 14 round pilings to wrap 4. Poured concrete foundation walls I chose this system for the following reasons: 1. Wall Curtain system: This was a dream. The simple use of the sealant and 2 foot curtain is something I didn't see from any other system and it made a huge difference in effort. I was able to hang the wall curtain in 3 hours by myself. The system made this possible. I was worried about the strength of just using sealant after so much research showing butyl tape and pins but it's strong I tested it a number of times through the process. 2. Seam sealer: I didn't see any other system recommend to use a seam sealer tape as recommended by this system. This was key in my application because I wanted to have a watertight installation. I had seen too many reviews and mistakes with just tape sealing and how water will seep through. I didn't want this. This installation was VERY challenging for me in my tight crawlspace. I wish that there was an option to have this preinstalled on at least the wall curtain. I wasn't able to do the quality job I was looking for just because of variations in the ground as I tried to put down the seal tape. Part of this was my fault. I should have pre-installed it myself before putting up the wall curtain but hindsight is 20/20. 3. Service: I called HB at your crawlspace and he was quickly able to determine my needs answer my questions and get my order sent out quickly. Much appreciated. 4. Videos: I really appreciated all the how to videos provided. It's really all you need to get things going. You will run into challenges like how to wrap pilings and how to manage sealing around plumbing and other things in your crawl but as far as the system goes the videos are all you need. Youtube the rest.

I found the your crawlspace information online after doing a google search. I needed to replace a 10 year old installation that that was failing. Bennie was very helpful and spent a lot of time with me making sure I had everything I needed to have a successful install. The new system is much better than my previous one. I used a 2 foot wall curtain and the magic adhesive which went on flawlessly. The 36 mil floor barrier is also far superior than the previous 12 mil liner that I used and much easier to work with. The new tape also made sealing the floor seams much easier. Took about 2 days total to tear out the old system and install the new with just 2 people. I saved about $6000 doing it myself as apposed to hiring a company who would have installed an inferior system. Thanks very much

The folks at YCS were very helpful and friendly in deciding which products to use. Pictures are before and after of our crawlspace project. Hanging the crawl curtain with the sealant was easy, cutting the 36mil ground vapor barrier to size and placing it was easy, using the seam tape to secure the crawl curtain on the piers to the floor vapor barrier and to open floor seams was fairly easy (pulling the stuff off the roll takes some effort, is there a quick release backing version?), taping the seams around the perimeter was a pain because of how sticky the tape was and needing to make it a 90 degree corner. It often got stuck to itself, the curtain, or the vapor barrier where it wasn't intended (even when taking our time). We finally decided to pull out about 3' of tape, fold it lengthwise with non-sticky side against itself, attach to the floor material first, then roll up the side. Approaching the end, we found I hadn't estimated enough seam tape (left out a seam, cuts in material to go around piers, or both); needed about 40 feet more. Left a message on the YCS web site with a follow up phone call the next morning for another roll. They shipped immediately and billed me. I recommend YCS put out a video on the best way to tape wall curtain to floor material with seam tape. Perhaps the answer is to use Seam Weld tape on top of the 36 mil product with the curtain material on top, but I thought the wall curtain belonged underneath. We got it done (well, most of it) and it looks good, has dropped the radon level to .4 and falling (with an extraction fan/pipe under the fabric), and I think the humidity level will drop as soon as the last few seams are done and given a little time for the insulation/wood to give it up.

Great service, great product, and I am very happy with the final results of my crawl space. I called several times to ask for help on the installation process and the individuals who I spoke with were extremely helpful and took the time to properly explain the installation process. Along with the results, I was highly impressed with the knowledgeable group of employees who are willing to go that went the extra mile to help me through the install.

Both Bennie and HB were very helpful in assisting with what was needed to complete my encapsulation project the right way as well as with what was not needed and would have been unnecessary expense. Their system is user friendly which in turn made for an efficient installation. This was our first time doing a crawl space encapsulation and I would recommend their product for both the experienced or the novice like myself. Thanks again for all your help Your Crawlspace!

We received everything we needed to do a complete encapsulation of a crawlspace in Texas. Crawling around with about 18" of clearance wasn't the most ideal conditions, but the YCS system made it fairly easily. We use the wall curtain which was super easy to put up with the adhesive. The 36 mil vapor barrier was easy to work with. It was flexible enough for us to squish it underneath plumbing pipes about 3" off the ground. The ordering was easy as YCS calculated everything we needed based on the information we gave and we had very little waste at the end. I would highly recommend these products.

Excellent product, excellent customer service. We used their wall curtain, adhesive tape, caulk and 36mil vapor barrier. I am wrapping up an installation of an encapsulated crawl space in a new construction house by myself (a female) in North Florida. I was dead-set on us doing the encapsulation ourselves and not hiring it out in order to save money. My husband and neighbor chuckled/rolled their eyes when I said I would just do it myself...and I showed them! I think I have watched every video out there about every product that exists for an encapsulation and when I saw Your Crawlspace's system and the fact that it didn't need bolts screwed into our new stem wall, I was immediately interested. The owner called me soon after I submitted questions online and answered them. Their prices were below other products and were SO much easier to work with than what I would expect had I needed to drill into the stem wall. They estimated what I would need and I had very little waste. They called or emailed me to answer any little questions I had along the way. You can tell they know the issues in a crawl space, they've invented proven products that work, and they are a good family-owned business. I know I saved a bunch of money doing it myself. I was patient and did a few hours at a time, but it wasn't anything that a halfway fit person couldn't do on the their own. I hope I can make it up to Charleston to shake their hands, because they've been great to work with and it's a great product!
