"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

"Perfect wall LLC service was amazing! They went over the job with me and explained everything and taught me a thing or 2 about insulation. After the job I went to look at the results and it was exactly how he explained it! They use measuring templates you can see the actual depth of the insulation in all parts of the attic which was awesome. The vent out the exterior wall was so perfect I couldn?t even find it unless I really looked. Everything came out perfect they took the time to clean up very well also which my wife was very happy about! 10/10 would use again."

"Recently had my attic insulated by Best Homes. Chris and his crew were professional and very efficient with their work. They insulated my attic within a few hours and left my house cleaner than it was before they got there. I wouldn't want the job done by anyone else."

Insulation FAQs, answered by experts

Using plastic shrink film over the window will cut down on drafts, which makes the air inside your home feel warmer. Plastic shrink film doesn’t quite have the insulative properties of a new window or of adding insulation inside the window jamb, but it will help. Plus, it’s a cost-effective solution to keeping your home warmer.

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

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.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency.
