"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"

"EZ insul did a great job removing old fiberglass under an addition of our home. Due to rodents we needed this removed and replaced swiftly. Jake communicated quickly and effectively. This allowed us to continue with our other projects. Additionally the EZ insul team rolled out drop cloths to keep everything clean and were very respectful of my home."

"Where oh where do I start with Robert! There are TOO many good things to say about working with this man! The first time I ever used home advisor was find a contractor that could do spray foam insulation. Right off the back he contacted me very quickly regarding my inquiry (another pro took 4 DAYS) I loved that he explained the process to me (I was thinking of DIY foam), but didn t try to steer my decision to hiring a professional. He laid out the facts and let me choose. He was able to check out both my houses right away and followed it up with two quotes like he said he was going to do. It is the WORST when someone says they re going to do that but never do. I hate having to ask repeatedly. With Robert you don t have to worry about that. His quote came in at HALF of his competitors price! He was very helpful at providing me a multitude of different options on each house to fit all the requirements of the town. The spray foam insulation when finished came out beautifully and he left the place cleaner than when he started! But here s the kicker... Robert went above and beyond his insulation expertise. He seemed knowledgeable beyond just the insulation so I asked him if he was proficient in any other types of construction. Turns out he s a jack of all trades and knows his stuff! I needed some serious last minute help on my houses and Robert delivered. I was in shock! He helped with demo, framing, installed cabinets and doors, and coordinated with my other contractors to problem solve some issues. I couldn t be more thankful to have met him. It s hard to find great, fair, reliable, affordable contractors nowadays. Robert has old school work ethic though. He has pride in doing his best. I m so glad to have him part of my flipping team. You will not be disappointed if you hire Robert Lamothe I can promise you that! Things went so well with Robert that I used home advisor again to search for a plumber. That worked out just as well too!"

FAQs for insulation service projects in Dudley, MA

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.
