Crawl Space Encapsulation You Can Count On
You can look no further. We are Fenwick.
Closed crawl spaces or encapsulation is one of our specialties, and we are ready to work with you to improve the condition/health of your home or property. The reality is your crawl space and first-floor living space exchange air about 8-15 times a day. The government estimates as much as 50% of the air you breathe can come from your crawl space.
It’s safe to say it’s very important to get the job right the first time, giving you peace of mind, knowing the structure cavity right below your first floor living space is moisture and mold-free, free of water damage, free of rot and unwanted pests but also saving you from thousands of dollars in unwanted repair work. Getting the job done for you, right the first time, by a company like Fenwick, means you have selected a vetted and proven expert, certified by NORMI as a Certified Moisture Control Professional (CMCP).
If you haven’t closed, conditioned or encapsulated your crawl space, you’re likely having a moisture-related issue. Almost everyone has or will have issues in their crawl space. As a matter of fact, it’s estimated by the government, damp building syndrome effects as much as 60% of all U.S. homes or buildings. You want to be proactive. We will prevent today’s issues from becoming tomorrow’s expensive problem in the future.
Crawl space encapsulation can not only save you energy and improve your air quality but in the long run, will save you thousands of dollars. Fix or prevent all issues with moisture, mold, and pests and provide you and your family with a more healthy, stable environment.

Why Close, Condition or Encapsulate Your Crawl Space?
Closing, conditioning or encapsulation involves installing high-quality protective vapor barriers inside your crawl space that covers the floor and walls. You can think of this like installing a liner to a pool except in reverse. Unlike a pool, we are keeping the water and moisture from entering the liner.
Why is this process so important? An encapsulated crawl space is dry and clean. This means that there is no support to mold growth and potential spreading up through the floor to your kitchen, bedrooms, or living room. Dry and clean also means that there is no moisture to rot away your wood framing or foster wood destroying and nuisance pest infestations.

The vast majority of homes do not have these money-saving crawl space features, so if yours needs help, give us a call. While crawl space encapsulation will fix any damage that has already occurred, it will also prevent future damage and add to the overall value to your home. Invest in this system now, so you won’t have to worry later.
Your crawl space will be clean and moisture-controlled, just like it should be. Next, we’ll share a bit about the steps we take to get you there.
What to Expect from Crawl Space Encapsulation

At Fenwick, we help ensure the reliability of your crawl space encapsulation through a variety of controls. Smart ventilation makes sure that good, fresh air comes into space, while any bad air (moist, humid,) is removed. Dehumidification controls humidity during long heat and humidity spells. Both make sure that moisture and condensation can’t possibly form on your crawl space surfaces to ensure your crawl space does not go back to the moldy, damp space it was or would have otherwise become.
