"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"This company was extremely reliable and worked very fast to get the job done. We used them to renovate an apartment for rent and they were honest with their prices and even suggested options to save us money. We would definitely utilize them in the future and recommend them. I wish I had taken before and after pictures to show what a great job they did. Also, we were really impressed that the contractor sent us pictures and contacted us every time they completed anything."

"I was seeking a significant augmentation of insulation in my attic, since the existing insulation was 31 years old, and had become very thin, and shoved around over several decades of work up there. After vetting 4 contractors, I chose Western Pest Services, and was very pleased with the entire process. they did a thorough evaluation of the attic space, evaluated my plan to run the installation tube through a 2nd floor window, and confirmed that there are no pests in the space. I felt that the price was fair - and the technicians did a terrific job in less time than I had expected. Definitely recommend them!"

"I hired AGL to insulate my basement. When they first came out, they found a water issue in the walls. Instead of just spraying anyway, they advised me to wait a few days for it to dry and do something about the water. I had my contractor add a concrete barrier around the house to keep water away from the walls, and they came back a few days later to do the job. They also left me commercial fans to help dry the place out. They did a great job on the foam, and my basement is extremely well insulated. Sometimes it's warmer down there than in the rest of the house! I'd use them again any day."

"Steve calmed my fears and did the job in two phases at a great price. First all Mold was removed. Second Steve’s Cree came out and built the French Drain in my basement. In both occasions Steve’s crew came out on time and worked very hard to get the job done. Steve kept in constant contact with me during the process and sent pictures of the completed job. I highly recommend Steve for his professionalism and Honesty."

"We had a cracked ceiling and sagging ceilings in 3 rooms, and a portion of drywall hanging but off the nails, larry and his son, replaced the broken pieces and shored up the rest with drywall nails, and insulation, and in some cases new drywall. A dirty, difficult job, which had to be done two days in a row as it required furniture moved and painters to follow. He recommended a painter for us as well, which allowed us to set the whole thing up for one week of inconvenience, but got the job done. He and his son were pleasant as well which helped through this trying experience. Since this problem is uniform through our development we had seen where ceilings had caved in on others and were caving in slowly on the rest and wanted this done before anything fell down on us and hurt us or guest. Larry cut out two days to do 3 rooms, which allowed us to set the painter up for completion. We also had to bring in a electrician to shore up a ceiling fan now that the ceilings were set properly."

Insulation FAQs, answered by experts

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.
