"Job started a day later than scheduled due to their equipment being down. Job was originally scheduled for 5-7 days. Job actually took 2 weeks and salesman called into the third week saying the job was done. We have never had mold remediation done before and was selling our house. The explanation of how the job would go was vague at best. This is not a process we are familiar with having never been through it before. In the estimate there was a blanket statement of “any construction materials removed will not be replaced” (once again we were never explained anything about this process in regards to things being removed). Upon the job being completed the buyer noticed there was no mention of insulation replacement. We were 2 days from closing and had to hire someone to replace the insulation. The handyman hired to replace the insulation noticed other items had been removed by octagon. We were not left a list of items removed from the residence. I was just told by Matt Brown that “that’s why I gave you a referral of a weatherization company” for 8300$ one would think you might get a verbal explanation of items needing replacement or at least an itemized list. Hope we don’t need to go through this again because as Octagon will not be contacted again."

"Bob contacted us right away via phone. I explained what we needed done (purchased the legs of an old lathe that were quite rusted and needed to be sandblasted before we could repurpose them as table legs). He made an appointment with us for the next day to give us an estimate for the project and showed up at the appointed time. He took the legs with him to sandblast them in his shop and promptly returned them the next day ready for us to paint them!"

"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."

Insulation questions, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

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.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.
