"Brayden and his crew were as friendly as a favorite relative! They worked professionally and neatly. And cleanup was complete and exact. The final walk down also proved to be encouraging as well, with everything put back in its place! I wouldn't hesitate hiring them again in the future ever! They were GREAT!!"

"I had someone come out to my home to take a look and they were very professional and answered every question I had. The install guys came a couple days later and they were both great and showed me the work they did and I was very pleased. So far I have noticed a huge change in my bill and will definitely be recommending to my friends and family!"

Insulation FAQs, answered by experts

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

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.

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®.
