"We had water damage due to a leak in our roof. We contacted Octagon because of their glowing reports on Angie's List. I cannot say enough about the company. Jessica, the coordinator, was very professional and excellent at keeping me informed on who was coming and when. She assigned the project to Heather, one of the project managers. We were extremely pleased with Heather. She was incredibly professional and very well educated in water damage mitigation and mold remediation. She called to let me know when she was coming, arrived on time, inspected the damage, immediately knew we had a mold problem and began the work to remove the molded areas and installed a HEPA filter to clean out any spores floating around as a result of the work being done. She communicated in detail everything regarding the job -- what she saw, how she was going to fix it, etc.. etc.She even crawled up into our attic to see if there was any damage above the ceiling -- truly above and beyond. As this was an insurance claim, she worked with State Farm to ensure that everything that needed to be done for our benefit was discussed with and agreed to by our claims adjustor. I cannot say enough about both Heather and Octagon. Heather explained that the owner of the company hired professionals and everyone was expected to have at least one certification in one of the areas that Octagon provided service in. It was evident by my experience with all their employees that they hired and retained the best. I would most definitely use them again and highly recommend them to anyone."

"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!"

"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."

"Our old water heater died.  Called around for some estimates, he was the best price.  I got someone on the phone right away. Richard the owner was out to give me an estimate within a few hours, and then came back to install the next day.  Great guy, great service, great price.  I'm also looking to have him do some work on my house - in the process of getting estimates for exterior house painting and a partial bathroom remodel.  Would definitely recommend to friends."

Insulation FAQs, answered by experts

Insulation can be easy to install, depending on the condition of your walls, but there are many safety considerations and potential challenges involved. For example, most types of insulation are made from materials that can cause irritation if inhaled or if they come into contact with your skin. Additionally, installing insulation incorrectly can actually make moisture issues in your home worse.

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.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.
