"This September I had a home energy audit through Fulkrum Insulation. They said we needed some Ductwork changes and more insulation in the attic. Since having those solutions installed, my electric bill has been dramatically lower than ever before."

"They were a bit over the rest of the company’s that I had out. But the pease of mind that I had knowing that they were going to do it right was worth it. During the bid Mike answered all my questions before I was even able to ask them. Made a great impression on me. They also worked well with me removing my old insulation myself. PLUS , they hauled off the old stuff for me at a great price!! Thx guys!"

"We had two separate appointments, one for duct cleaning and one to add insulation. Both crews were professional, clean, efficient and polite. They were all responsive to questions and feedback. I will definitely hire Climate Doctors again in the future and will have no problems referring them to friends, family, co-workers, and my Real Estate clients!"

"Excellent Service from Start to Finish! All I needed was an upfront and honest salesperson and that’s exactly what I got. I told them I just wanted my 10x20 shed spray foamed so I could turn it into a workout room. Robert and his crew took the time to clearly explain the job and process from beginning to end. I was upfront about my budget, and they worked with me to make it happen without any hassle. The job was completed on time, and every team member was incredibly professional. They didn’t leave a mess, no garbage, no overspray and even cleaned up the leftover dust. I highly recommend Leon Foam Pro for any spray foam insulation needs. Great people, honest communication, and quality work!"

Insulation FAQs, answered by experts

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter. 

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.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”
