"These guys were great. I had both my attic insulation upgraded, but also my home's crawlspace re-insulated. They were very respectful of my space, explained everything they were doing and answered all of my questions. They are a hard working customer oriented team. I would not hesitated to recommend this company to anyone."

"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."

"We have worked with many different contractors over the years and have been turned off of construction in general. None of our previous projects have ever gone smooth. The opposite can be said about home genius Exteriors! Joe was in communication with us throughout the project and made sure any issues and concerns we had were addressed immediately. This has been a really good experience and I highly recommend home genius Exteriors."

"Angel installed a new vinyl floor, cabinet, and sink in my laundry room. Also replaced an interior door, and did troubleshooting on a leak we were having in our sunroom. Angel stayed in touch throughout the process, arrived on time and did flawless work, we couldn’t be more pleased. Would highly recommend for any home improvement projects you may have."

"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!"

"Wow... just wow. I feel like the clock rolled back several years to the days when tradesmen where available, on time, skilled and affordable. Koala is a rare find. These guys have it all together. Sal is the sparkplug that makes it work seamlessly. He guides you in just what you need, and nothing you don't need. His estimates are detailed and very fair pricing. After consulting with Sal he was able to schedule the work in less than a week. The installation crew called ahead on the scheduled day and arrived exactly on time. Shawn led the crew of 4 techs who worked neatly and thoroughly, and cleaned up well. They did rim joist sealing and batt insulation in a somewhat complex situation where I have I joists adjoining the band board. They also did blown in fiberglass in the attic. For anyone considering insulation of any format I highly recommend Sal and Koala. And, the best part of this experience with the company....the total cost less than others who had rebate programs."

"Unfortunately, when the techs started the process, the insulation already in the walls prohibited the addition of the foam. I cannot begin to tell you how disappointed I was, as the job they had done on our tiny addition was remarkable. However, isn't it wonderful to have a company tell you the truth!"

FAQs for insulation service projects in Williamstown, NJ

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
