Coastal Window & Door is a Marshfield company that installs windows, siding, and roofing for South Shore homeowners. Its one Google review, from March 2026, comes from the quote and design stage: the homeowner said salesperson Ewan Sellars took the time to walk through every option and explained the details clearly, and was looking forward to seeing the new windows, siding, and roof go in. With the one account on record centered on the sales conversation rather than the finished installation, it's worth asking about the crew's timeline and workmanship when you get your own quote.
Such an enjoyable quote and design experience with Ewan Sellars! He took all of my preferences and priorities into consideration and spent quality time explaining the nuances of my options. I can not wait to see my new windows, siding and roof!!!
Typical Greater Boston range for this kind of work, from regional averages — not a quote from COASTAL WINDOW & DOOR. 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
