Crawl Space Encapsulation & Sealing Services

Stop Mold and More

What is keeping water, insects, gases and odors from entering your home? If your home has a dirt or gravel base, the answer is nothing if it's not properly encapsulated.

There are many reasons why your family and your home would benefit from a crawl space encapsulation system. Let's say you put your head in the crawl space right now. Do you smell a damp and musty odor? Is the air humid? Can you see water on the ground or wet discolored areas on the crawl space walls? If you look at the wooden floor joists, do you see mold or wood rot? In the winter, do you notice the floor above the crawl space is cold or drafty? We have just walked you through some standard questions in our inspection process. If these are problem areas for you, ask us about crawl space sealing and insulation today!

Crawl Space Sealing is The Solution

Now that you are familiar with the symptoms of an unhealthy crawl space, lets talk about our crawl space encapsulation system installation process.

  1. We remove any debris so that we can properly assess the walls and floor.
  2. We level the soil or gravel as much as possible. If your crawl space has a concrete floor, there is no leveling process.
  3. Add drainage matting, a first layer on the ground that provides tear resistance and protection to the liner, delivers waterproofing channels, and pads the floor for anyone crawling around in the area in the future to move boxes and items.
  4. Size your basement crawl space and encapsulate it with a reinforced vapor barrier liner. This reinforced liner is very different from what you can get at the local hardware store and will not easily puncture or breakdown over time like the plastic alternatives used by builders.

Seal & Insulate Your Crawl Space

Properly sealing and insulating your crawl space will deliver additional protection from humidity and environmental problems.

First we seal the wall and floor liners together with our waterproof tape and secure the liner to the wall with fasteners and sealant. Now that the walls and floor are sealed and secured, our installations technician will look to seal the floor joists and any air gaps with closed cell spray foam. Next we replace missing, damaged or rotting vent covers or crawl space doors. The final step in our crawl space sealing and insulation process is installing a dehumidifier which will help clean the air, control humidity, and protect whatever you decide to store in your encapsulated crawl space.

Case Studies


Encapsulated Crawl Space

I called Alliance for a quote on encapsulation of my crawlspace. The price was extremely fair. Workers came out on time, removed old insulation, filled foundation cracks, and encapsulated the crawlspace. The job was done excellently and professionally by a great team. Very responsive, no sales gimmicks or up-selling. Just an honest company with hard workers doing a great job.

Encapsulated crawl space

Very Professional. Crew that did the job were so hard working. They did an excellent job. They leveled the floor in the crawlspace, installed drain tile and installed a sump pit and pump. They also encapsulated the crawlspace with a heavy vapor barrier.
