"It was about 30 degrees outside and around 45 inside. Furnace not coming on. I went to Home Advisor to setup a quote and I was still considering the three recommendations, when the phone rang. This guy was on the ball! He was at my home in less than 30 minutes and had diagnosed what was wrong, fixed it, made some recommendations, upgraded my old thermostat and got us up and running in no time! He even did some extra maintenance for free. Very good service. Very friendly and professional. We definitely will use him again."

"We just had a roof done by home genius exteriors. We started with Justine at our door setting up an appointment for someone to tell us about the process. The next day Dan came and explained how the company works. He even crawled around our attic to show us the damage. Within 2 days our roof was in the process of being installed. Zach the project manager stopped by 3 times during that day to see how the work was being done. What a professional company. Everyone that we spoke to or met was very professional and friendly,. I would highly recommend this company for installing a roof."

"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

Insulation FAQs, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

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.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.
