"We have a building and it is so old that it never had insulation in the walls. The winters were very uncomfortable because of the cold that would come thru the walls. Sound from the apartment above carried like the person above was right next to you. I called Ecorite and made an appointment with Danielle to have an estimate. Uri was on time and took measurements then gave us a written estimate. Big wow for us since most of the time we are given a verbal one that keeps changing until a contract is written. We told Uri our issues and he made suggestions. He explained the products and how they use them. Closed and open cell materials and what walls they need to go on. Next was the actual installation. We had to make some changes and Danielle made sure the contract was updated and I approved the changes. She made sure everything ran smoothly. When the workers were on their way Danielle made sure I knew it. When the Kenneth and Lucas (the workers) arrived they were on time and greeted us then introduced themselves. They were friendly and pleasant and they made us feel comfortable with their knowledge of the product, and respectful of our home. They instructed us on how to reduce or eliminate any incontinence to the other tenants of the building. During the installation they worked non-stop, until they broke for lunch. After lunch break they were in a hurry to get back to work. There was no slowness here; if I had to use a word I would use quick€. After the job was done they cleaned up and took out the trash (which for us is a big thing). The entire job was a pleasant experience. I will be calling back for the next apartment. If not for Homeadvisor I would not have found such a good company. We are very happy."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"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."

Insulation FAQs, answered by experts

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.
