"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."

"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."

"The gas company came in to replace a meter.  They found that the vinyl siding company we used in the past had cut and covered the safety valve.  The one night that it's super cold out, the gas company had to shut off our gas (heat)!! I called Richard at 9:00pm.  He got back to me first thing in the morning and had his crew take care of it by 7:30am.  They are really THE BEST!!  The gas company is here now and hopefully we'll have heat soon."

Insulation FAQs, answered by experts

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.

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.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.
