"I received several estimates and all where way above $2000 with most necessary items as additional charges. Matt's estimate was below everyone else with everything included!! Matt was professional and very personable and did an excellent job. I would recommend him over anyone else!! And I don't recommend anyone unless I stand behind my recommendation! Thanks For a great job. P.s. I installed a thermometer in my attic and although its not freezing yet, the temp range between attic and out side are in range and my furnace hasn't been running as much so far, can feel a big difference in the house!"

"Attic Air absolutely lived up to their reputation. They did a GREAT job! I did my research in creating a short list of 3 bidders for the job. I have a bi-level house (4 levels) with 2 attics. We had black mold on the underside of the roof which we had remediated a week before having Attic Air come in to fix our ventilation and insulation issues. Our upstairs floor was cold in the winter and hot in the summer. The attic ventilation and insulation needed to get fixed, and I wanted to make sure I hired a good company to do it the right way so I never had to worry about it again. I made the right choice. The temperature throughout the house is so much more even now. Before Attic Air came out, the basement and sub-basement were freezing and the first and second floors were warm and hot. My over-sized top of the line Trane a/c unit was working overdrive to try to cool the 2nd floor and never could do it. The top floor is so much cooler now than before. It's really going to save my a/c unit in the long run. Attic Air was not the lowest bid of the 3, but you get what you pay for. If you want to get the best quality this is the company you want. I would haven't have changed a thing. Worth every penny!"

"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!"

"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)."

"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

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

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.

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.
