"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"Victor was very thorough, suggesting additional services that I needed but hadn't thought of...namely insulating the water lines in the attic. He not only added the blown-in insulation, but also sealed cracks and replaced or added vertical insulation on skylights and knee walls. All was done at a reasonable price, 25% less than the other bidder."

"My insulation project was more difficult than is typicaly expected, access to far corners of previous insulated attic. 805's crew was successful in insulationing previous overlooked area's. I am experiencing 4 - 5 degrees more warmth this winter reducing my heating costs 15 -20%. John S. SIMENZ & COMPANY CONTRACTING SERVICES INC."

"I'm extremely impressed with Luis and Icon Insulation. After moving into a 115 year old house about 5 months ago, and having a lot of contractors doing various jobs, Luis was a breath of fresh air! I had him Insulate my attic, and then I had him back again to insulate under our floor. I would highly recommend Icon Insulation to anyone I know. They are very responsive and answered all my questions before our appointment, punctual, professional, and have a great work ethic. (Something hard to find these days.) Thank you for your great work!"

"We had no problem or issue with this company. They came and did exactly what they said and promised. The service was fast too. We were able to schedule them for the same week and the work was completed after 2 days of work. According to the technician that worked at our house, it was better to use the opportunity when the attic empty from the old insulation and to replace the ducts as well. For the price that we were able to got, we decided to do that too.
so overall, we are in the stage that we will use this company in the future and we will refer them to people that we know and might need the same kind of work to be done.

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.
