"In July 2024 I hired Insulation Labs to add more insulation to our attic. They showed up on time with a truck full of insulation, and a few hours later they had put all of it inside our attic. They did a good job up there. I am very pleased with how everything turned out. One thing that distinguished Insulation Labs from some other outfits is that they did not try to up-sell us with services we didnâ t need."

"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"Overall great experience with my blow-in cellulose insulation project. David was courteous throughout, took time to explain the various insulation products, helped me decide what was best for my objective. The installation team was meticulous, from preparation (protecting floors and covering furniture) to a spotless cleanup. Price was competitive and fair. Highly recommend!"

"The Best in HVAC and Insulation Services! The Attic Doctors are a game-changer! We needed a new air conditioner and decided to upgrade our insulation and duct work as well. They offered an incredible deal to do all three services together. The installation was quick and professional, and we noticed that our house is so much comfier after the insulation and HVAC upgrade! It is rare to find a contractor that handles everything with such expertise. We are beyond satisfied and highly recommend their services!"

"Tech who showed up to do inspection was thorough. Climbed into small attic, took pictures and explained what their findings were. Other inspections (I had 2 more) just popped their heads into the entrance and too my word for what may need to be done. Scheduling with Attic Construction was simple. They showed up on time (early). They let me peak up their as they cleaned up old insulation and remove rodent droppings (biggest concern). They finished within the day as promised and cleaned up after themselves thoroughly. Our home was well protected from dings/damages as they wrapped corners of walls, stairs etc. We have noticed improvement from having only 3.5 inches of insulation to now nearly 14-15 inches. They recommended a "combo" of batt insulation (Around the entrance) and blown in for the rest of the area. This allows you to pop in there with out blown in insulation falling all over the place. They also recommended and performed rodent proofing/sealing. We were sent photos of both before and after their work. I would highly recommend this company."

Insulation questions, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.
