Winchester NH's Trusted Insulation Contractor

“This was my second time working with the Farnum team. This time was just as exceptional as the first. The expertise and knowledge of Jeff and Will guiding me through the energy audit and the suggested improvements was invaluable. The whole crew was efficient, pleasant and respectful of my property. Their communication was top notch from start to finish. I would recommend this company without hesitation.”

“Farnum insulated my 1820s home, starting with the basement, which now stays around 64°F—even during single-digit days. After roof insulation, my upstairs bedrooms are 4-6°F warmer, and the house heats up much faster. The crew was polite, efficient, and left everything spotless. I’ll definitely work with them again for future projects!”

“Financing and rebates are often important to many homeowners. Through it all, Farnum Insulators provided excellent support and service in all parts of the process!”

“Great work! Our home is super efficient now. Received nice check after service from VT Efficiency!!”

“Excellent job with the spray-foam insulation: thorough, efficient and neatly done. We appreciate the professionalism and high quality of workmanship provided throughout this job.”

“What a great company! They were fast, courteous and did a perfect job. I am so grateful they managed to fit me into their very busy schedule. It was a pleasure working with you, guys!”

“The Farnum crew did an excellent job of insulating my attic. They were professional; passionate about their work; mindful of my property; and cleaned up after themselves. I would HIGHLY recommend them!”

“Is there a way to give more stars?! Everything about working with them is great–start to finish. They are communicative, friendly, courteous, and professional. The quality of the work is top notch (there was a lot of carpentry involved, too, for my home). Everyone on the staff was a pleasure to work with. I wish I could hire them for all my home projects!”
