"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I had several options to pursue in finding a remedy for my hot attic. After meeting with the insulation consultant who was extremely knowledgeable, patient, and provided detailed explanations of how to insulate I knew proceeding with the job was the right decision. My attic is noticeably cooler and I highly recommend USA Insulation Tri -State"

"My house is a little wacky and the proposal was to include all of the crawl space and ceiling surface area. Sadly there was no way to know that a portion of both were inaccessible to insulate. Was hoping to fix issues with freezing pipes by insulating but that is the part they could not access. The scheduling and some staff on the phone is a little dry on the phone. The crew who came to do the job worked their butt off and were super nice. CJ, who drew our proposal, was very nice and knowledgeable. He warned me that his estimation might be a little off but the estimation of the Pepco energy saving percentage back ended up being way off after the energy audit. That made the job much more costly than predicted and I had not planned for that. He was willing to adjust the bill slightly but not significantly enough to really make a difference. Overall, it is going to make a huge difference in the comfort in the house and the crew was very professional."

"The team arrived slightly early to be well prepared to start the job on time. As they began they laid down protective barriers to keep the home clean. While in the attic they blew in the insulation with an even consistent barrier, ensuring that all locations with infrastructure were well covered. As they wrapped up the job, they cleaned behind them as they closed up the attic, removed the floor coverings and were on their way. The only way I can tell they were here is that the heat runs less in the winter and the air conditioning runs less in the summer. I would recommend this process and this team to anyone who owns a home and has not insulated their attic."

Insulation questions, answered by experts

Minimal but regular checks can ensure maximum thermal performance.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.
