Brookline sits just four miles from downtown Boston, tucked into Norfolk County as one of the most distinctive communities in all of New England. First settled in 1638 as a rural hamlet known as Muddy River, it was incorporated as its own town on November 13, 1705 — after 32 freeholders signed a petition to the Massachusetts General Court demanding independence. That independent spirit never left.
The housing stock tells the town’s story well — Georgian Revivals, brick multifamilies, Craftsman bungalows, and modern condos line the same blocks. Single-family homes carry median assessed values above $1.5 million. Residents who take that kind of care of their properties don’t compromise when it comes to home improvement — and they’ve found Coastal Windows & Exteriors to be the window company in Brookline that meets that standard!
