"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"I had a great experience with Attic Pro. From start to finish, their team was professional, knowledgeable, and respectful of my home. They did an excellent job removing the old attic insulation and replacing it with high-quality insulation products designed to improve energy efficiency. The crew worked efficiently, kept everything clean, and took the time to explain what they were doing and why it would make a difference. You can tell they take pride in their work and care about doing the job right. I’m very happy with the quality of the work and the overall experience. If you’re looking to replace old attic insulation, improve your home’s energy efficiency, and have the job done by a professional company, I would definitely recommend Attic Pro!"

Insulation FAQs, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
