"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"Chris and his team are the pros to call for any rebuild or remodel job. We cannot recommend them enough. They have done other work at our house as well, and we are always incredibly pleased. For this job, they came in and installed drywall and taped our new bathroom. They are always on time, take time to explain everything, and are super clean (you would never know there was a construction team in the house). When you hire integrity, you know the job will be done right. Cannot recommend them enough!!"

FAQs for insulation service projects in East Haddam, CT
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.
