Few towns in Norfolk County carry their history as quietly as Avon does. Named for Stratford-upon-Avon — the birthplace of William Shakespeare — this compact South Shore community even features the Bard’s portrait on its town seal. That’s the kind of civic pride you don’t manufacture.
Avon officially incorporated on February 21, 1888, after separating from Stoughton. Its roots stretch much deeper, though. The first settler arrived around 1720 — Moses Curtis, a blacksmith from Braintree — and the area he chose, once called Curtis Corners, became one of the most isolated spots in the Massachusetts Bay Colony’s sprawling “New Grant.”
Today, Avon sits just 17 miles south of Boston along Route 24 — well within the Greater Boston commuter belt — making it a prime South Shore address for families and businesses alike. The Avon Industrial Park, home to more than 127 firms and over 3,600 workers, transformed the town into a regional employment hub without erasing its quiet, residential feel. It’s the kind of place where neighbors know each other — and where a home’s condition still matters.
With New England winters rolling in from the south and coastal moisture drifting up from the shoreline, Avon homes work hard. Well-fitted, Energy Star 7.0 certified windows aren’t a luxury here — they’re just good sense.
Here’s how we make window replacement in Avon easy from start to finish:
The cost of window replacement in Avon, MA depends on several factors — and every home is different. The average cost of window replacement in the US is $22,000, which serves as a helpful national benchmark. Your actual investment will vary based on:
