Introduction

Congratulations on your decision to install the most advanced and simplest crawlspace encapsulation system available. Creating a closed crawlspace is one of the smartest decisions a homeowner can make to help conserve energy, preserve value, and maintain a healthy living environment in a home. We at Your Crawlspace stand behind our product and system and are confident that you will be extremely satisfied with the final results.

CAUTION: If you’re familiar with crawlspace encapsulations or sealed vapor barriers please follow our procedures and don’t use past techniques to attach our system to the foundation wall.

PLEASE FOLLOW THESE SIMPLE INSTRUCTIONS. Not only will drilling holes or using mechanical fasteners damage the foundation wall, they will compromise the effectiveness of the Crawl Curtain.

If used as instructed, our system will save hours of labor costs, easier on installers, and performs better than any other system. These installation instructions have been extensively tested in the laboratory and in thousands of homes nationwide.

YCS Wall and Pier Adhesives

The Your Crawlspace Magic Sealant / Adhesive is VOC Compliant and works on almost all foundation walls in any condition. The adhesive will attach to metal, brick, wood, stone, block, dirty, wet, dry, even over spiderwebs. Consider a test spot if concerned your foundation may not receive the adhesive. Please contact YCS with any questions.

Building Code Compliance

Due to local building code variations, home owners are responsible to verify and comply with all local codes and requirements. If there are any questions or concerns with the structure, or any of the systems in your home a professional foundation contractor should be consulted.

If you have a pest control contract, we also recommend consulting your company to be certain they approve the system. Some companies require a treatment before installation and a wider inspection strip than the building code. The Your Crawlspace system complies with the International Construction Code.

Certification and Training

For certification and training on the YCS System please contact us. We can come to your location or we offer regular training one day classes in out Mt. Pleasant location.

Step 1 – Get To Know Your Crawlspace

Before we get into the installation, let’s review some of the more common terms for parts of the crawlspace. By being familiar with these terms, you will have a clearer understanding of the installation process:

(See instructional videos at YourCrawlspace.com)

Step 2 – Initial Crawl Space Inspection

Prior to installing any new materials, an assessment of the crawlspace should be done to determine the extent of preparation involved. By checking this list beforehand, you can be sure your crawlspace will be a safe place to work.

The following is a check list of things to look out:

_____ Check for adequate access to the crawlspace

_____ Debris in space (garbage, old building materials, etc.)

_____ Check for Insects (termites, wasps, bees, etc.) May need to treat for pests before install.

_____ Look for animals or other critters (rodents, snakes, etc.)

_____ Check for pooled water on ground

_____ Check for wet or damp ground in the crawlspace

_____ Note levelness of dirt in crawlspace

_____ Crawlspace Insulation (fiberglass, foam)

_____ Check wood joists & framing condition

_____ Verify column & support locations

_____ Note drain & vent piping locations

_____ Note water supply piping locations

_____ Check for plumbing drain leaks

_____ Check for sump pumps & condensation pumps

_____ Verify ductwork condition and locations

_____ Note air handlers and fan locations

_____ Note foundation vents

_____ Note wiring and other electrical devices

_____ Check for adequate lighting

_____ Check exterior drainage around house

_____ Gutters and downspouts

_____ Ensure that water is directed away from the foundation

_____ Is there a gas operated system in the crawlspace? *Must be vented properly.

 

If any of the items on the check list are problem areas, they need to be either removed or repaired as required.

For example, if there is standing water in the crawlspace, then that water needs to be either pumped or siphoned out and the low area filled in with dirt so water will not accumulate there. You may consider a sump pump.

We want to make sure that the crawlspace is a safe place to work, so if there are any damaged wires, duct work, or broken plumbing, please make repairs as required to meet your local code. If there are items in question, please consult with a building official or a construction professional.

Step 3 – Check that your crawlspace access panels or doors are large enough to easily enter and exit the crawlspace. It is recommended that the door is at least 4” higher than exterior grade and that the door is made of a non-corroding material. Use foam weather striping or other means to seal the door air tight when closed and provide a positive means to hold the door closed such as hasps and latches.

Step 4 – Ensure that all debris, including wood, cans, tires, bottles, masonry block, bricks, large rocks, sharp objects and any thing else that will hold water, attract critters or possibly cause a material puncture is removed. Consider the YCS 38 mil padded vapor barrier for wet or rough areas.

(See instructional videos at YourCrawlspace.com)

Step 5Provide adequate light to do installation. Two strings of six bulb lights work best. 15 min setup.

Step 6 – Inspect top 3 to 12 inches of Inside of foundation walls and other support structures a to make sure it will receive the adhesive. Consider testing a spot if in question.

Step 7 Cracks at sill plate and bottom joist must be sealed air tight. YCS Magic Sealant / Adhesive is recommended for gaps from 0” to ¼”. Spray expanding foam should be used for gaps wider than ¼”.

Step 8Ensure that a minimum 3” wide* termite inspection gap is clearly visible around top perimeter of foundation wall. If evidence of termite or other pests are found, be sure to remedy the situation before going further with the installation. If you have a pest management professional, check with them to ensure that the crawlspace encapsulation system does not interfere with their system or warranty if applicable. *May consider larger inspection area (3” to 12”) depending on termite activity in your area.

Step 9 – Foundation vents and other exterior wall penetrations must be sealed air tight. This is accomplished by using 2” rigid foam insulation cut to fit snugly in the interior side of the vent opening. The foam can be held in place by adhesive. Use expanding foam or caulk to seal any other openings and cracks to the outside. Please contact YCS if you are in a flood zone. Our FEMA approved vents may help with flood ins.

Step 10 – Check that all appliance discharge pipes and ducts from kitchen, baths, laundry items and indoor air handler condensate drains terminate outside the crawlspace and to the exterior of the building.

Step 11Crawlspace soil should be leveled and crowned to eliminate the possibility of standing water. Smooth soil to prevent hills and valleys. Grade crawlspace floor to one or more low points. Provide drains or sumps at the lowest points if necessary. Slope all drain piping to daylight. Crawlspace drains should not be connected to foundation or gutter drains.

Step 12 – Moisture Control Measures – some of these suggestions will not apply to all installations, but each must be take into consideration and addressed if they apply to your home.

• Ensure that slope of exterior finished grade is away from the building. Provide a method to transport roof runoff away from the house, such as gutters and down spouts.

• Exterior of foundation wall surfaces should be water proofed when the crawlspace is located below exterior grade.

If required, provide drainage from under the vapor barrier to the outside with a sump pump system.

• If the crawlspace elevation is above grade, provide a floor drain in low point of floor.

• Provide flood vents when required by local code that will minimize air flow.

• Spray mold and mildew treatments to trouble areas and below floors of bathrooms or other areas where there is the possibility of leaks.

Step 13 – Prepare an accurate sketch based on measurements inside the crawlspace. Take note of all item locations that will need to penetrate the material, such as supports and pipes.

(See YCS Wall Attachment Tap instructional videos at YourCrawlspace.com)

Step 14 – Based on the sketch that was previously prepared; determine the most advantageous way to orientate the material to minimize cutting and joints. Always cut material to provide a minimum 6” overlap. Precut material for installation around columns and piers.

NOTE: (See YCS Wall Attachment Tape System instructional videos at YourCrawlspace.com) Only one side of the wall and pier curtain will adhere to a concrete, stone, brick or steel foundation all or support pier. Our patented material is 100% plastic coated on one side. No adhesive will attach to this side of the material, to the wall, or pier. The other side is completely coated except for a two in strip at the top. The light blue side with the activation strip goes against the wall and pier. Be sure that the fibrous activation strip is on the wall side of the material.

Step 15 – Install material around all columns and piers. Material must be a minimum of 12’ up piers. Use adhesive around perimeter of the column or pier and use vinyl tape to seal the seam. Apply adhesive with a bead that is approximately 3/16” of an inch in diameter. See Photos on Pages 8 and 9 for an illustration of a properly wrapped pier.

Step 16 – Install the wall material up the foundation wall, stopping 3” to 12” inches from sill plate. (If using wall insulation, leave material a minimum 4” from top of sill plate). Use a 3/16 inch bead of YCS Magic Sealant / Adhesive around the top perimeter of the foundation wall. Use the YCS Seam Tape, or YCS Magic Sealant / Adhesive for vapor barrier seaming. YCS Seam Tape will NOT work on the foundation wall. If your liner gets wet the tape will not adhere properly.

This step is best accomplished by two workers. As one worker applies the adhesive bead near the top of the foundation wall, the second worker follows, pressing the wall material’s adhesive sensitive strip into the adhesive bead with his fingertips. Please press the liner completely into the YCS Magic Sealant / Adhesive.

Step 17 – Begin floor installation at furthest point from crawlspace access door. Pieces of floor material should be lapped a minimum of six inches. All lap joints are sealed with the YCS Poly Seam Tape or YCS Magic Sealant / Adhesive.

Ground cover should be applied so as to minimize ripples, wrinkles or stress on the material. Final installation should appear flat.

Note how the pier material is cut and wrapped. A finished pier ready for taping.

Step 18 – Insulate band joist with minimum R13 fiberglass batt insulation or per your local code. Putting insulation in the rim joist is very important.

Step 19 – Install a dehumidifier. Ensure that dehumidifier has a way to drain condensate water to exterior of crawlspace. This can be achieved by either gravity or a condensate pump. In lieu of a dehumidifier, a small (4” to 6”) supply vent can be added to existing HVAC ductwork if ductwork is readably available. The Department of Energy and the EPA recommend an air-flow of one cubic foot per minute (1 CFM) for every 50 square feet of crawlspace area. Most areas will need to have a dehumidifier for several months out of the year because we use very little conditioning.

Step 20 – Install remote humidity monitor.

A job well done!

Alternative crawlspace insulation technique:

1) You can use floor insulation when using a dehumidifier or wall insulation when using your HVAC.

*It is always a good idea to exhaust air or put negative air pressure on the crawlspace while installing the system. This will help with dirt, dust, and mildew from entering the home.

By following the YCS System you will have a properly sealed crawlspace that takes less time to install, that is safe for the homeowner and the installers. SAFE. SIMPLE. SEALED.

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.

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!

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!

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.

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.

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

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.
