"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."

"RetroFoam of Michigan deserves more than five stars. The representative who gave me an estimate was prompt and professional. The office staff who called to tell me installers were ahead of schedule was kind and courteous as I answered during a busy day at work. The crew who came to insulate my garage was extraordinary. They made sure my garage was left clean. They even mopped the garage floor before they left! The crew leader explained the process of insulating with foam and exactly how the holes in my walls would be patched before the team left. I am an educator of 30 years and a licensed builder. I've remodeled and flipped homes and have rental units. I'm used to swinging a hammer alongside others. This company is made up of hard-working people who charge a fair price and do exceptional work. I have advice for those that run the company - take care of your installation crews! They are exceptional! If you've read this far and are interested in having your house/garage insulated give them a call now. You will be happy you did. Now...I'm looking forward to enjoying a warm man-cave garage on cold nights!"

The owner went out of his way to make sure that I understood exactly the services I was to be receiving, and his team was nothing but respectful and left the house as clean as it was when they arrived.

FAQs for insulation service projects in Princeton Junction, 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.
