"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."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

Insulation questions, answered by experts

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.
