"Darrell did an outstanding job at a very reasonable price. He surveyed the existing insulation and recommended an additional amount to go from R-30 to R-60. He also performed additional work in accessing a sun room attic from the outside and blowing in fiberglass to R-60 at no extra charge. We notice the difference in heat retention in the home already. Looking forward to lower heating costs this coming winter. We highly recommend his company for your insulating needs!"

"This was our first time using Apollo Insulation and Geremy and Dennis did an excellent job removing our old (rodent droppings and urine) insulation. They disinfected and repaired any damage caused by the rodents. New insulation was blown in and we couldnâ t be happier. From the initial inspection and quote Geremy was on top of keeping us informed on what would be done to complete the job. Apollo Insulation cleaned up behind them inside and outside leaving our home with no mess. The price was very reasonable and we were very pleased and satisfied with the quality of the work. I highly recommend Apollo Insulation for any of your insulation needs. Very hardworking and professional service company. Bill and Anne G Wayne, Maine"

"Woke up to major water damage on a Sunday. I called Octagon and they were on site within 2 hours. They immediately set up to control the damage and handled everything with regard to my insurance claim. The staff were extremely professional and very pleasant. They arrived on time and kept me informed every step of the way. They clearly went above and beyond to make sure the job was done right. Their expertise is obvious and the caring they have for the customer is evident. Once I called them, all I had to do was wait till my house was dry again, they handled everything. would recommend Octagon with out any reservation! Cost of $2500 reported is full cost, I only paid the insurance deductible."

"Bob was on time, effecient, and honest. I thought I needed more insulation in the attic but he said I had 11" and that was excellent. He could have recommended that he add more, but he didn't and I appreciate that!"

"I have a heat pump as my primary heating and cooling device for the house. Late last Winter I noticed it was running alot and my house was still pretty cold. I called BRF and explained my concerns. The owner of the company personally came out to make sure the job was done correctly. He quickly identified a leak in my old system and was able to repair it. He then took extra care to make sure an adaquate vacuum was pulled on the system before topping it back up. The result was a huge bump in efficiency and rooms that are ice cold on the hottest days. I've only had to use the heat function once since the fix and it will drive you out of the house. The best part is that while we were waiting on the vacuum pump to do its job, he also gave me helpful information on increasing the efficiency in my home all around. It's pretty clear that he knew what he was doing and has a vast knowledge of the state run incentive programs."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Exposed ductwork can sweat just like ductwork placed behind walls, sometimes even more so. Ductwork sweats—like a cold drink on a hot day—because of a temperature imbalance between the air in the duct and the air in the room. In a crawl space or wall, this temperature can equalize faster due to the small space but in lofts and open rooms, that wouldn’t happen as quickly. Many people insulate their ducts for this reason.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

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.

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter. 

Spreading tin foil over your windows works similarly to radiant barrier insulation, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn’t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.
