"I have had several projects completed by Jakob and his company since buying my home in 2017. From little jobs to big jobs, Jakob is the only person I will trust with my home projects. His crew is reliable and hardworking. Jakob is hands on about EVERYTHING. From material orders placed, to deliveries, to getting permits, to scheduling inspections, to coordinating his crew for different jobs….. I honestly don’t know how he keeps it all running so smoothly. He built us a BEAUTIFUL paver/deck patio a few years ago, and this year he built us a STUNNING covered porch/portico with paver walkway which matches the backyard aesthetic. My neighbors have stopped to tell me how beautiful it is and they couldn’t believe how quickly it was finished. I very much appreciate how Jakob works with me to plan and make my vision come to life. He does the job well, and doesn’t cut corners. I feel confident and secure in his work, which is why he is the only person I will call when I need something done. "

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Greg offered a great price for insulating my vaulted ceiling with spray foam. He was here on two occasions, the second time adding an additional layer of foam on the ceiling. When done he cleaned up everything, and I couldn't be happier with the completed job. He stands by his work, and I truly appreciated the experience of dealing with him."

FAQs for spray foam insulation projects in Wantagh, 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.
