"We contacted ECO insulation because we wanted to improve the comfort of our home year-round. Kris inspected our attic and discovered that our insulation was below where it should have been following the original build and that there were several areas that were not sealed. We were wasting money via our less efficient insulation and energy use. ECO sealed all areas, increased the insulation, and we noticed our AC ran less immediately and kept our home cooler longer on our first 101-degree day. Thanks, Kris. We highly recommend your company and work."

"Streamline installed a garage ventilation system and attic insulation above our garage, would definitely use them again. Great people and service. Happy with the install, had questions a few days later and the representative was at our home in about 30 minutes. Highly recommended"

"these folks did blown insulation for me , that went well. The problem I'm having is getting documentation to submit a rebate claim to Dominion energy. Just can't seem to get it right. Haven't given up yet. Also ask about a small gutter fix and was told on its own wasn't worth there time, however if they were in the area on another job it could be. The price I was given was more than a previous job approximately 3 times larger. Same company installed. Little frustrating."

"Good work, fair price. Only complaint is they did not call me to set up an installation appointment. They just showed up one morning ready to install the insulation. It worked out because I was home anyway. I would gladly use them again but I would make sure they schedule an appointment."

"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."

Insulation FAQs, answered by experts

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.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.
