"Ceiling had numerous holes drilled with sporadic or no pattern, ceiling repair and patching was not part of contract we agreed upon. Took several days to prep and complete two jobs - blowing insulation into vaulted ceiling and spray foam on attic duct work. Workers left attic walkway messy, they came out right after I called and didn't bill me until they until cleaned up."

"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 questions, answered by experts

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.
