Most people know Hopkinton as the town where the world’s most famous marathon begins each April. Homeowners know it as a place with real variety in its houses. Antique homes and Victorians line Main Street and the streets near the town common. Capes, ranches and garrison colonials fill the neighborhoods that grew up in the mid-1900s. And newer colonials and larger homes keep going up on tree-lined lots near Hopkinton State Park, Lake Whitehall and in newer developments like Legacy Farms.

Castle “The Window People” of Massachusetts helps Hopkinton homeowners with energy-efficient vinyl windows and new entry, patio sliding and storm doors, all backed by the Castle Lifetime Guarantee.

Why Hopkinton Homeowners Replace Their Windows

Hopkinton is hilly, and homes on open hillsides and tree-lined lots feel the full force of winter wind. In older homes near the center, original sashes and loose storm windows let that wind right in. In homes built in the 1980s and 1990s, which is a big share of the town, builder-grade windows are hitting the age where seals fail, glass fogs and sashes stop sliding smoothly.

Large colonials with big two-story foyers and walls of glass in family rooms can lose a lot of heat through tired windows. New vinyl windows seal tight, help keep each room comfortable year-round, and never need painting.

Window Styles for Hopkinton Homes

We install vinyl windows only, with ENERGY STAR certified options available depending on the package you choose.

Entry, Patio Sliding & Storm Doors

A grand front entry deserves a door that looks the part and seals tight. We install steel entry doors, patio sliding doors for decks and patios, and storm doors that protect your entry from the weather. Each door is measured to its opening. See our door replacement options.

Our Install Process

It starts with a free, no-pressure in-home estimate. We measure every window and door, look at each frame, and talk through styles and glass with you.

Most of our installs are inserts, which keep your existing interior and exterior trim and keep the job neat and quick. If an old frame is damaged, we’ll recommend full-frame replacement for that opening. Most jobs are finished in one day. Larger homes with many windows can take a little longer, and we’ll tell you the schedule up front.
