"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"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!"

"What a terrific company! All Type Insulation Services Inc team is extremely knowledgeable, reliable and courteous, and they offered some excellent solutions to the noise problems in my apartment. Ron was readily available and nothing was too much of a problem for him to handle. I would certainly hire them again and I strongly recommend them to any business or residence that has a noise issue and need insulation service."

"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

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

EIFS (Exterior Insulation and Finish System) siding can last from 20 to 60 years, with some properly maintained systems lasting even longer. The exact lifespan depends heavily on several factors, most notably the quality of the initial installation and the consistency of maintenance.

Factors that can shorten the life of EIFS include:

  • Improper or poor-quality installation

  • Moisture intrusion

  • Damage from high winds, storms, or hail

  • Damaged flashing and sealant

  • Lack of regular maintenance and unfixed damage

To maximize the lifespan of your EIFS, it is crucial to hire an experienced and qualified professional for the installation. Additionally, regular maintenance—such as cleaning, repairing small cracks or blisters, and having the system professionally inspected—will help identify and resolve issues quickly, preventing long-term damage.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

You should not put fiberglass insulation in basements, since fiberglass is known to trap mold and mold is more commonly grown and produced in basements. You should also avoid placing insulation near water heaters, oil burners, or other hot appliances. For more information about the best and worst places to install insulation, consider hiring an insulation professional.
