"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!"

"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."

Insulation questions, answered by experts

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.
