"I am VERY late in writing this review, but as I was in the Angies List site I thought I'd put this review in. I can't say enough good things about Vaillancourt Roofing. I had a leak in my roof, winter was coming on and no other roofer would call me back. As an act of humanity Adam and Dave drove down from NH to look at my roof even though they don't do repairs in my area - Carlisle, MA ( I understand they could possibly do roof replacement in my area). They came when they said they would and they found the leak quickly. The leak was from my chimney. They aren't mason's necessarily, but they put a temporary fix to the chimney, so I could rest easy until the next Spring when I could address it. They didn't charge me and were done in about an hour. I wish my roof itself needed replacement, if it did I'd all them in an instant. Just wanted to put in this review as I owe it to these great folks."

FAQs for insulation service projects in Shrewsbury, 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.
