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!!!!"

"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."

"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

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem. 

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

EIFS (Exterior Insulation and Finish System) siding can last from 20 to 60 years, with some properly maintained systems lasting even longer. The exact lifespan depends heavily on several factors, most notably the quality of the initial installation and the consistency of maintenance.

Factors that can shorten the life of EIFS include:

  • Improper or poor-quality installation

  • Moisture intrusion

  • Damage from high winds, storms, or hail

  • Damaged flashing and sealant

  • Lack of regular maintenance and unfixed damage

To maximize the lifespan of your EIFS, it is crucial to hire an experienced and qualified professional for the installation. Additionally, regular maintenance—such as cleaning, repairing small cracks or blisters, and having the system professionally inspected—will help identify and resolve issues quickly, preventing long-term damage.

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.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.
