"We were referred to AJ Pro Green by a colleague so we had them come out for a free estimate. They showed up on time and were very professional. They insulated our basement during our remodel and we couldnâ t be happier. The job was done quickly, was within our budget, and communication was fantastic. We would highly recommended!"

"Warren did foam insulation to a gruesome crawl space and also installed a dehumidifier/fan to dry it up. He was very responsive, answered all my questions, was extremely polite, stayed under budget, excellent work done, and cleaned up every day. I m very pleased with all the work he did. I will hire him for more jobs. I highly recommend N.E.E. Construction and Spray foam."

"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"Quality Insulation of Portsmouth did two jobs for me: They added blown in insulation to my attic last fall and installed gutters plus leaf guards this spring. Both jobs were excellently done at a reasonable cost. I would certainly recommend them and will likely use them again in the future."

"Excellent! The carpenter that did the job, Jeff, was professional. My shed needed new doors and the front panels rebuilt. Jeff did this job with care and expertise. He, also, painted the new wood. I was particularly impressed with the skill he showed when rebuilding the doors."

Insulation questions, answered by experts

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

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.
