"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"Entire staff was knowledgeable, professional and courteous. The quotes we received were detailed and submitted promptly. When the day came to blow in the cellulose insulation in our garage, it coincided with one of the snowiest and slippery days of the year. The two man team arrived on time and stayed until 6:30pm to finish. End result...on budget, on time and the cellulose has made a big difference."

"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

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.
