"Excellent, from start to finish. The company contacted me within moments of my request. Explained everything, quoted me a price and set up a day/time that worked with my schedule. The insulation crew were friendly and professional. I paid when the job was done, shown pics of before and after. When they left you wouldn't even know they were there. No mess at all. Would recommend this company!!!!"

"Had the whole house insulated in 2016. Just found out that there is now mold in the attic. Have had three different contractors come to look at it and ALL have said the reason is because when the insulation was blown into the attic they did not take the time to rake it away from the soffits. Now I'm faced with a major repair bill of $3000 to eliminate the mold. Plus, to make matters worse, my utility bill did not go down very much after having this done. Only thing I can say is that the house is more comfortable. So beware if you use this company and make sure they install the insulation into your attic correctly!"

"We used Fox Foam to install blown-in insulation in our attic and to properly vent our bathroom exhaust fan. We recently had our roof replaced and switched from tan shingles to black shingles - with the new color, the house was noticeably hotter and our aging A/c unit couldn't keep up. I contacted several contractors and Andrew at Fox Foam was the only one that returned my calls promptly, was able to get me scheduled quickly, and was reasonably priced. They came out and completed the job in just a couple hours and provided pictures of the attic when they were finished. The very next day the temperature shot up to the mid-80's with high humidity (which is right about when my central air would start struggling) - the house is noticeably cooler, the A/C isn't running all the time, and I can't feel hot air pouring in from the bathroom fan like I could before. I would definitely recommend Fox Foam."

"My wife and I attended a presentation by James Manfield, the owner of GreenForce.  We were impressed with company product and Jame's punctuality, professionalism and honesty.  We decided to hire his company to add insulation to attic of my in-laws house.  The installers came on time and over 9 hours managed to complete 95% of the job.  The installers were polite, professional and clean.  The subsequent installers came next day and completed the job.  We are very pleased with James and the service provided by his company. As FYI, we had similar radiant barrier installed by another company in our own house in 2012 and we were pleased with the reduction in heating and cooling cost."

"Salesman did a great job. It took time (longer than I expected) to get the treatments and the follow up has been average to poor. Time will tell if this was a good investment. It was very very expensive. Critters pulled many of the installed bait stations out of the ground and they had to return to reinstall the ones that I could not push back into the ground. I had to call a number of times to remind them that they were to return to reinstall the bait stations and to check for carpenter ant control."

FAQs for insulation service projects in London, OH

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.
