"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

"Working with N.E.E. Construction & Spray Foam on our project to build a ramp in our garage for easier access was a breeze! We posted a request on Angi’s for pros to build a ramp and Warren from N.E.E. Construction & Spray Foam was quick to respond. Within 1 week of our post we had exactly what we needed. Communication is very important to us throughout any project we do and Warren & his crew (Matt and Patrick) did not disappoint. They delivered what we wanted within the timeframe they promised and at the price they committed to when quoting the job. And the quality … fantastic! Take a look for yourself. Thank you Warren, Matt and Patrick from N.E.E. Construction & Spray Foam for restoring freedom and independence to our family."

"Overall experience was good. One problem after they were done. They did not remove covering on lights or smoke detector. When asked to return to remove them they agreed to come but never showed up."

"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"At the beginning of the project, Roland called me back right away and was able to get schedule the job quickly. Roland was very professional and showed up "on-time", did an exceptional insulation installation for preparations of my zero clearance wood stove insert. I am a very happy customer and I highly recommend him. 5 stars"

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

FAQs for spray foam insulation projects in Merrimack, NH

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.
