Coastal Industries, Inc.

Coastal Industries has been making windows and doors out of its own Haverhill facility since 1973 — a genuinely rare setup, since most window companies in this directory install someone else's product rather than manufacture their own. The company, still family owned according to its own site, serves customers across Massachusetts, New Hampshire and into Maine with vinyl replacement windows, storm windows, doors, porch enclosures and screens. The handful of reviews on file are notably specific about aftercare rather than just the sale. One customer, writing in late 2025, called the installation work well done and every staff member courteous and skilled. Another, in a 2024 review, described a tree crashing through a brand-new replacement window during a storm — Coastal treated it as an emergency, came out quickly, built a replacement, and had it installed within days. A Reddit poster, posting in 2026, separately described buying storm windows and then six vinyl double-hung replacements installed in 2023 for $4,500. One thing worth confirming directly: the state registry shows the company's Massachusetts home improvement contractor registration as currently expired, so it's worth asking about its status before signing a contract. Its BBB page also shows an A+ grade but lists the company as non-accredited, even though other directories cite BBB accreditation as one of its credentials — a discrepancy worth a quick check on BBB's own site if that distinction matters to you. For a straightforward window or door replacement from a company with over five decades on the same street, Coastal is a reasonable call — just confirm the registration is current and get the manufacturing lead time in writing, since this is a small operation making its own product rather than installing off a shelf.
