"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!"

"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

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

Periodic checks for moisture or pest issues ensure consistent performance.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.
