"I hired Ramon and his team to do my attic insulation. He was flexible with scheduling over two days as we needed to replace ductwork for our HVAC in the attic. His prices were WAY better than anyone in Northern Virginia. He was able to come out in two days to remove all the old and dirty insulation that was thirty years old. The attic was cleaned and air gaps sealed. He came back promptly when we were for the insulation installation. Not only did they do a great job at sealing but they did a great job at spraying 18 inches of R49 Fiberglass. They were professional, timely, and cleaned up after themselves. They went above and beyond my expectations. I am so happy and would gladly recommend these guys for anyone. Five stars!!!"

"Terminix provides an ongoing service for termite and pest control.  They come approximately every 3-4 months to spray around the outside foundation.  They are available to check any concerns that I may have inside or outside the home. <br />   I feel their services are reasonably priced.  I have had no issues with infestations of any kind.  The cost varies from a maintenance fee to a specific spraying if necessary. <br />   Their technicians are friendly and very helpful with answering questions.  They let you know when they arrive and unless you have any concerns, they give you an approximate time of how long they will be there."

FAQs for spray foam insulation projects in Williamsport, PA

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.
