N.E.E. Construction & Spray Foam is a veteran-owned insulation and remodeling contractor based in Concord, New Hampshire, with the business stating 26 years of experience. The company offers free estimates and is hired for spray foam insulation, ADA-compliant disability access ramps, deck construction and repair, and kitchen, bathroom, attic, and basement remodeling. Across dated written reviews spanning 2020 through 2025, the company built a strong, consistent track record: 18 of 19 reviews on file are five stars, with the single remaining review still a positive four-star account rather than a complaint. Reviewers repeatedly credited owner Warren, identified by full name Warren Preston in a 2022 review, along with crew members Matt and Patrick, for responding quickly to inquiries, showing up on time even in difficult weather, and leaving job sites clean when finished. Specific projects described in the written record include spray foam insulation in a crawl space and beneath a four-season room (2020), reconstructing house skirting alongside insulation work (2024), and an ADA-compliant garage access ramp (2025), along with several deck rebuilds and repairs. In a 2023 review, a homeowner described the final invoice coming in lower than the original quote, with the difference refunded unprompted. The company states it does not offer emergency services or warranties, so homeowners with an urgent need or who want written warranty coverage should confirm those details directly before booking. Because the written reviews on file run through mid-2025 rather than the last several months, it's also worth confirming current availability and crew capacity for a new project.
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.
GREAT COMPANY. WE HAVE USED THEM 3 TIMES. HIGHLY RECOMMENED
Had a hard time finding someone to replace the railing on my second floor deck when a falling tree took it out. Warren was immediately interested in my job, came out on time and gave me a fair estimate. On the day he said his team would be out to fix it I expected them to cancel because it was only 16 degrees out! They came out, did a great job in one day and cleaned up before leaving. We're very pleased.
Warren's response to our inquiry was within a very short time of the posting. He was very understanding of what was needed and supplied an estimated time involved, cost of the project and a time frame of completion. His attention to detail was impressive with any questions we asked, answered honestly. We are certainly pleased with the high quality work and would not hesitate to contact Warren for future projects.
Courteous, knowledgeable and hard working. Communicated well through the whole project. Very pleased with the insulation and reconstructing of some of the skirting. They also did a really good job of cleaning up. Highly recommend!!!
