"Gus (owner) came out to provide an estimate. He was in the attic for about a half hour looking over the space so that a complete estimate could be provided. Several weeks later Gus came out and added blown in fiberglass insulation which made the area an R-60. While Gus insulated the attic, he took pictures on his cell phone and showed me the completed work."

"We recently had blown in insulation installed in our home and couldn’t be happier with the experience from start to finish. The team was kind, professional and incredibly prompt. They showed up on time explained the process clearly and treated our home with respect. What really stood out was the pricing after receiving a much higher quote from another company their estimate was very fair and transparent with no pressure or upselling. It was clear they care about doing honest work at a reasonable price. The installation was completed efficiently, and the whole process was smooth and stress-free. I would definitely recommend them to anyone looking for insulation work great service, great value and great people."

"Nick and his crew were so informative and pleasant to do business with. We had attics insulated, new vents installed, and outside blown-in cellulose, and they worked long hours to make sure everything was done correctly. I would definitely recommend this business. A great surprise was how the insulation muffled loud outside noises (fireworks and loud vehicles)."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

Insulation questions, answered by experts

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.
