"Spray foam team discovered that some of vapor barrier in crawl space was loose. We were really impressed with how quickly the team that handles that work responded to a request for assistance. Even with that extra work, the job was done on time and was well done. Impressed with both the staff both in the office and on the job. Easy to reach the office. We highly recommend them."

"The owner met with me and explained the details of the project. He took time to consult the general contractor of the new log cabin to make sure he covers everything. The job was finished ahead of schedule. He had the best prices, quality of work and excellence of customer service. I was apprehensive because his prices were lower than other proposals but the quality of work speaks for itself. I am very happy I went with this company."

"I hired Kevin to do insulation work in my home in Bartlett, NH and I could not have asked for a better experience. He was very honest and knowledgeable from the very beginning and made us extremely comfortable and informed throughout the entire process. He was on time and very thorough. We had a couple estimates done and the price could not be beat! We had such a great experience and could not recommend Kevin enough!"

FAQs for spray foam insulation projects in Porter, ME

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
