Warmer floors were the result described in a 2025 review: Dan and crew insulated the basement-to-first-floor cavities, including the foundation sill plates, and the customer noticed a large temperature difference on the main living floor. In a 2024 review, a customer said John and Dan installed cellulose insulation on the second floor and attic of a 1940 Cape in Greenland and left the site clean. Seacoast Renovation and Insulation says it has been in business for 30 years. A 2024 customer said John and Dan visited on a Sunday to estimate insulation for a barn renovation and finished the job that same week; the customer praised Dan's cleanup and called the price fair. In a 2024 review about insulating a three-season porch, the customer said John and his team evaluated the job the next day and were honest about what they could and could not do. Carpentry extends to decks: a 2024 customer said John and team renovated a deck with Trex, added white trim against the house foundation, and stayed on budget. A 2024 customer who needed a quote during a home-buying inspection period said John supplied it the next day, allowing the customer to meet the seller's deadline.

Prompt, fair & quality work. Would recommend
John, Dan, and Bill were fantastic to work with. All three of them are very easy to work with and understand the details of their craft. They were clear up front with what they would do and the estimated cost. The final product is exactly what they promised. I will be working with them for my future housing needs!
Super Prompt service. Dan and crew insulated the entire basement to first floor cavities including the foundation sil plates. The floor can now be walked on barefoot without wincing! Massive difference in the temperature on the main living floor. I’m a super happy customer! I will call them again for my next project! KDillon
I called to get an estimate for insulating a space I’ve been renovating in my barn. John and Dan came over on a Sunday to look at the job, then had it finished that same week. I’ve never experienced a turnaround that fast. I was impressed by Dan’s work; it was professional and he left the space cleaner than he found it. Great guys, fair price.
We were having a hard time finding someone to insulate our three-season-porch. Based on some online research, I reached out to John at Seacoast Renovation. Him and his team were there the next day to evaluate the job. They were very thorough and took their time addressing the best way to approach the job. They did amazing work and were very honest about what they could, and couldn't do. They are at the top of our list for all things renovation and insulation. Thank you John, Dan, Phil, and Sa. Great work!
