"This was the second time I hired zavza seal. This time I needed help with attic insulation for my parents house. Starting with setting up the free appointment, ending with the crew and quality of the work - they deliver a great experience and I highly recommend them for anything waterproofing, insulation, concrete and foundation fixes.

"The type of work I needed done was literally beyond over 12 other companies I had to my home for an estimate. Some very popular companies (which are supposedly experts) at cleaning up the situation I had in my basement. The situation: Foam Insulation that was sprayed in all the Wellâ s / Between All Jointâ s through out the entire basement of a 3 Bd Rm Ranch. The Foam HAD to be removed due to Termites. All Exterminatorâ s stated the Termiteâ s could not be treat until the Foam was removed. To my complete surprise and obvious delight that they took the job was beyond wordâ s. Some very (as they stated) were the best â ¦ yet some actual stated; â Ummm -,I never seen this nor been ask to remove it.â One company wanted $250 for the first hour and $150 for each additional hour - with a quote of taking 3 dayâ s to complete the job. The estimate for the job never exceeded more than 1 day -,there was no surprise or statementâ s that it was an impossible job to do. They arrived on time - - took 2 / 10 minute breaks and completed everything within only several hours. I was absolutely amazed and thrilled. Professional and completely committed to finish the work. I absolutely recommend if your in need of anything foam insulation. Even removal. Iâ m extremely happy with the work and the professionalism. An absolutely top rated company and recommended if you need anything foam insulation related you to look no further. Thank you so very much for all the work you did! ."

"Moises and his crew repaired water rotted wood in difficult locations and completely finished the garage to every detail from insulation to molding, as shown in pictures here. They thought of every detail that shows their pride over their work. Not only is their work top notch, but they are also easy to work with and very communicative through the whole process. I have already hired them for a second job."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"We just had a roof done by home genius exteriors. We started with Justine at our door setting up an appointment for someone to tell us about the process. The next day Dan came and explained how the company works. He even crawled around our attic to show us the damage. Within 2 days our roof was in the process of being installed. Zach the project manager stopped by 3 times during that day to see how the work was being done. What a professional company. Everyone that we spoke to or met was very professional and friendly,. I would highly recommend this company for installing a roof."

FAQs for insulation service projects in East Islip, NY

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.
