"We had a leak in our roof that for years I'd been trying to figure out from where it was coming. Water is tricky because where you're seeing it doesn't mean that's the source ("water finds a way"). Finally decided to call in an expert and Adam Vaillancourt Roofing was the first company that was listed in a Google search. The first thing I noticed was the company's consistently high customer satisfaction results (at least 4.5 stars). Customer service is very important to me when doing any work to our home, which is our biggest investment. I called and spoke with Cat Vaillancourt to set up an appointment. We met with sales rep Jose Luna, who conducted a thorough inspection and found the leak easily. His presentation about the company and how they do their work was impressive and Jose was very professional. The meeting included a video that Jose shot while on our roof in which he explained not just the issues that were found but WHY the work was needed. He patiently answered all our questions and never pressured us into agreeing to anything. It's our money, it's our decision, he said. After meeting with Jose, we didn't hesitate to sign a contract immediately to get the work done. One of the biggest factors in signing was that the folks who do the work are company employees, not contractors. Fast forward a few weeks later and Paul Camarro and his crew showed up at the house on time and ready to work. When they were done, Paul showed us photos of the completed repair work, so I knew they delivered as promised. Jose is in the process of making a follow-up appointment so that he can inspect the job and make sure that we are completely satisfied. From Cat Vaillancourt and Mary Kay Macfarlane in the office to Jose to Paul, every person we dealt with at Vaillancourt was fantastic and professional. Their emails often include the signature, "The Team at Vaillancourt Roofing" and it's obvious that they truly are a team. We will absolutely be calling Vaillancourt in a few years when our roof needs to be replaced. Highly recommend!"

"Great response for not a big job of repairing a 2×2 hole, some patches and installing baseboard. Repairs and patches were done quickly and cleanly, was able to accommodate my changes to the baseboards and installed new trim matching the old trim perfectly."

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.
