Customers say: Quick response

"Needed insulation in basement and in attic. Got a prompt response for an estimate, no delays in getting the work done. Charged what they said and were respectful of our schedules and to our home. Our house is noticeably warmer and less drafty. Helpful in getting the paperwork together for a state rebate. Great company."

"We were referred to AJ Pro Green by a colleague so we had them come out for a free estimate. They showed up on time and were very professional. They insulated our basement during our remodel and we couldnâ t be happier. The job was done quickly, was within our budget, and communication was fantastic. We would highly recommended!"

"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."

"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

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.
