Verified record
Plymouth Bay Fiberglass is a Marshfield, Massachusetts business that manufactures and installs wood-replacement fiberglass gutters, offering custom profiles for both historic renovations and new construction on the South Shore. The written record is thin. In an April 2019 review on BuildZoom, a homeowner described escalating quoted prices and daily payment demands during their project, rating the experience 1 out of 5. Separately, the business shows a 4.5-star average from two Google ratings, though neither platform carries enough volume to settle which better reflects typical service. Massachusetts's state license registry lists the company's Home Improvement Contractor registration (HIC 177200) as expired, worth confirming directly before booking. Homeowners considering fiberglass gutter work should also ask for a clear, itemized quote up front given the billing concerns raised in the 2019 account. For homeowners specifically seeking a fiberglass gutter specialist rather than a traditional aluminum installer, this is a niche fit, but current licensing and pricing in writing are worth confirming before work begins.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Plymouth Bay Fiberglass. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$4,000 – $11,000
Typical exterior project around $7,500
This company is ridiculous. I am not even sure how they are still in business! They nickle and dime you through the process this is after they quote you on the job. They quoted me one thing and the price kept going up daily then they wanted payment daily for the work they did. I have NEVER seen a company run like this before and will be reporting them to the better Business bureau
