At Seal and Supports we talk to numerous people who have been concerned about their crawlspace for a long time. They call because what they believe to be the correct way to take care of their home just is not working. We hear things like "I open my vents in the summer and close them in the winter." or "I noticed water dripping from the duct work so I installed a fan."  

At Seal and Supports, we encapsulate crawlspaces because it is the only long-term solution.  The additional benefits from an encapsulation are numerous, from keeping your home structurally sound, to preventing harmful mold growth, to saving money on your energy bills. 


 On this page you will find a list of the benefits of encapsulating, studies and articles written by people who have done extensive research, links to web pages with additional information, and much more. 


 Experiencing frustration? Damage to your home? Discovering mold? Rotting wood? Sagging floor joists? Musty odors? In today's world people do not have time to become an expert outside of their profession. It requires extensive time studying and researching. Some people spend a lot of money to solve crawlspace problems. One customer worked unsuccessfully for an entire summer to get his ducts to stop sweating, but the water continued to drip from his duct work and puddle on his vapor barrier. It eventually stopped in the fall, and he thought he had his problem solved. Unfortunately, the following spring, the problem resurfaced. The changes in the seasons effect all aspects of your home, including your crawlspace. An encapsulation solves all those problems. Here is a list of symptoms you may be experiencing that an encapsulation would prevent.​​ 


Lets start by answering that question. It is simply a matter of separating the home from the harmful outside elements. The moisture in the soil and from outside air is very harmful. An encapsulation easily seals and protects the very important structural underside of your home from these outside elements.  


When Seal and Supports encapsulates, we start by doing a quick cleaning of the crawlspace. Sharp objects, debris, and organic materials must be removed before the encapsulation can begin. Some leveling may also be necessary at this time. Once that is done all the major openings are sealed using rigid foam board, spray foam and caulk. This includes the vents and the opening where the HVAC duct enters the crawlspace. The next step is to install a skirting on the walls and the columns. This prevents moisture from moving in through the porous walls. Then a thick liner is installed across the floor and a special tape is used to seal the seams. Finally, a weatherproof door is installed. Since you cannot completely prevent air from entering the crawlspace, a dehumidifier may be needed or dry air must be introduced.
