"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!!!!"

"Talkedto Steve at the home and garden show and set up an appointment for an estimate.
When he came out, he told me right up front that they were pretty backed up due
to the bad winter. I was fine with that and set a date that was good for both
of us to have the work done. They called the day before to remind me of the
appointment and showed up on time and did the work in one day. They did a great
job, cleaned up after themselves and you couldn?t even tell that they had
popped off the siding to drill the holes for the insulation.

"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."

Insulation questions, answered by experts

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.
