Coastal Windows & Exteriors

In a December 2025 review, a customer wrote that Coastal Windows & Exteriors replaced the windows and sliding glass door of their condo at the lake, swapping foggy, drafty windows for triple-pane Harvey windows that keep the energy in and make it noticeably quieter inside. Another December 2025 customer described new Harvey windows, a sliding glass door, a Provia entry door and a storm door, wrote that their energy bills decreased drastically, and said Coastal helped get their HOA's approval. The company says it was founded in 2010 by Stephanie and David Vanderbilt, describes itself as woman- and family-owned, and says it provides replacement windows, roofing, siding, doors and gutters in more than 730 towns across Massachusetts, New Hampshire and Maine. This location is in Bedford, New Hampshire. In 2024 the U.S. Small Business Administration named Stephanie Vanderbilt the Massachusetts Small Businessperson of the Year, and a June 2026 news item reports a 2025 James Hardie Service Excellence Award for the third consecutive year. In March 2026 a Nashua customer wrote that Ryan helped them choose Portfolio Craneboard vinyl siding, that site manager Steve came by every couple of days, and that the project was done in three days. In January 2026 a customer wrote that, facing an incoming northeaster, the crew worked dawn to dusk on their Kittery home's roof replacement, replacing rotted trim and soffit and installing GAF shingles, with manager Steve Schofield keeping them informed. In April 2026 a customer wrote that Nick and Sam explained the different windows patiently and found financing that worked. In March 2026 a one-star reviewer wrote that, after a visit to price siding, one representative asked for a five-star review on the spot; after the reviewer gave three stars, the second representative called the reviewer's husband about it, someone else called a week later asking why, and the quote for siding the back of the house never arrived.
