"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

"Attic Fanatics did an outstanding job from start to finish! The team was professional, punctual, and explained every step of the process clearly. They removed the old insulation, sanitized, sealed air leaks, and then installed new insulation — everything was done with attention to detail and care for our home. What impressed me most was how clean they left the job site and how much cooler and more comfortable our home feels now. They even shared before-and-after photos so we could see the difference in our attic. It’s rare to find a contractor that goes above and beyond like this. I would highly recommend Attic Fanatics to anyone looking for attic insulation or ductwork — you won’t be disappointed!"

Insulation FAQs, answered by experts

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.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.
