Customers say: Quick response

"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."

"The company was very supportive and accommodating. They took their time during the initial visit to review our attic before supplying a competitive quote which we accepted. They stuck by the quote during the completion of the job even though part of the attic required some additional insulation. Both Jose and Sergio were extremely thorough and professional. I will definitely recommend them to others without hesitation."

"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."

"We just have it done every three months. If we find an insect or something between times, you would call them. They'll come right out and do whatever has to be done. We had so many insects come in that one time. I don't remember what they were now. They've been here about a month before. But they came out an took care of it at no extra charge. They're helpful. I mean, if you call them in the middle of a between-times with a problem, they'll come out. We had spiders this last fall, and they came out and brought these little traps that you put down. And we got rid of them. Within a week I didn't see any. One time we had a mouse in the pool shed, and he ate through a bunch of stuff. So they came out and brought out the stuff to put down. They didn't charge anything; they just dropped them off one day when they came and were out this way."

Insulation questions, answered by experts

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.
