"Cody was excellent to work with. He was very professional, personable, and made the entire process easy to understand. He explained all of our options clearly, answered every question thoroughly, and never made us feel pressured. You can tell he genuinely cares about helping customers make the best decision for their home. Highly recommend Cody and the team at Coastal Windows & Exteriors."

"I recently had the pleasure of working with Coastal Windows & Exteriors to replace five basement windows in my 1920 home in Manchester, NH, and the experience far exceeded my expectations. From the very first visit on October 9, 2025, Frank and Cody arrived promptly and immediately put me at ease with their professionalism, deep knowledge, and genuine care for my project.They took the time to walk me through every step of the process in clear, patient detail—from the initial measurement and product selection to the installation timeline, removal of old storm windows, and final cleanup. What impressed me most was how attentively they listened to my priorities: energy efficiency with triple-pane glass, safety (especially with tempered glass in larger units), and maintaining a clean, white interior/exterior finish to match my home’s aesthetic. They didn’t just note my concerns—they revisited them throughout our discussion, confirming each specification (like the Vytex Potomac sliders and double-hung windows) and ensuring I fully understood how each choice addressed durability, insulation, and long-term performance in a basement environment.Cody, as my dedicated representative, with Frank sitting beside him, worked in tandem and was thorough in explaining the scope of work, including boarding two double-hung openings during critical measurements for safety, a detail I truly appreciated as a female homeowner who is not handy with tools. That is truly what I call going above and beyond the scope of their work and showed their ethical commitment to doing what is right.The contract was transparent, easy to read, and was reviewed prior to Frank and Cody departing my residence. When I later decided to switch from financing to cash payment, the change order was handled swiftly and signed on October 15, 2025, with zero hassle.Frank and Cody’s collaborative approach made a potentially overwhelming project feel straightforward and reassuring. Their expertise, combined with Coastal Windows & Exteriors’ commitment to quality and communication, has left me confident in both the product and the team behind it. I highly recommend Frank, Cody, and Coastal Windows & Exteriors to anyone seeking exceptional service and superior craftsmanship. Sincerely, Sandra"

"We met with Connor in our home today regarding a new front entry door with sidelites. He impressed us with his knowledge of ProVia doors and his description of how Coastal Windows and Exteriors operates as a company. Connor listened carefully to our situation and specific needs. We never felt pressured. Together we came up with a door design that my husband and I love. Connor was thoughtful and patient as we moved through the process. We are very impressed with this company and with Connor. We highly recommend you call them if you are in need of doors, windows, roofing or siding."

Cost
Window pricing is driven by how many openings you're replacing, the size and style of each unit (double-hung, casement, bay, or specialty shapes), the frame and glass package you choose, and the condition of the existing framing. Homes needing rot repair, custom capping, or difficult second- and third-story access take more labor. We don't quote a per-window price sight-unseen — we measure every opening in person and put the full scope in writing before any work begins.
