"I have a construction background but was unfamiliar with encapsulation as I just moved to Georgia. After extensive review of the encapsulation systems that were available in the area, and the price difference, I concluded the Crawl Space Doctor was a good fit. The main reason I chose the Crawl Space Doctor was because of their system. The other system was double the cost of the Crawl Space Doctor, so I carefully reviewed the difference and felt I would be getting equal benefits. I selected a 90 mil film for my project. Greg was very prompt and articulate in explaining his system and how his team would complete the work. Greg and his team did excellent work. They took out all of the debris under the house, informed me of a few problems they detected and repaired, then went to work putting the encapsulation system in place. They were very efficient. The crawlspace is doing exactly what I expected. The benefits of the Crawl Space Doctor's system are these: I am breathing better air quality. I am noticing a difference in the temperature of the house with reduced cooling costs, and expect the same on my heating costs. My insulation and floor joists are no longer moist and susceptible to mold. My heating and cooling ductwork will last longer with the humidity gone from the area. The dehumidifiers Greg put in do not run continuously, they will cycle off once the humidity desired point is reached. My hardwood flooring will not buckle in the future due to excessive humidity. My vents are now permanently sealed so rodents can't come into the house in the winter. I have peace of mind knowing my home is more protected with an encapsulation. It is a no brainer product in that it is a good investment all around. I would highly recommend Greg and his team at the Crawl Space Doctor. He has been doing encapsulations for years and is an expert in the field. His team does the work, but he personally oversees the project. You are in good hands with Greg McBride of the Crawl Space Doctor!! You will not regret spending less for top quality!"

Insulation FAQs, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Yes, an automatic pool cover retains heat. It can act as a thermal blanket because the heavy vinyl traps heat underneath, keeping the water warmer than if there wasn’t a cover. Keeping the pool cover closed when the pool’s not in use can also help reduce water utilities and save on pool chemical costs because there won’t be as much evaporation.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more.
