Shrewsbury grew up in stages, and you can still see each one in its houses. Streetcar-era homes went up in the early 1900s as the town became a suburb of Worcester. Summer cottages appeared along Lake Quinsigamond, in places like Edgemere, and many have since become year-round homes. Then came the post-war boom of the 1950s and 1960s, followed by the colonials and newer subdivisions that have filled in nearly every corner of town since the highways arrived.

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

Why Shrewsbury Homes Need New Windows

Each era of home has its own window problem. Older homes near the town center and along the lake often have single-pane sashes, worn storm windows and frames that have been painted over so many times they barely move. Post-war capes and ranches tend to have early replacement windows that are now past their prime. And many colonials built in the 1980s and 1990s still have their original builder-grade units, which are starting to fog, leak air and stick.

Lakefront homes face extra wind and moisture coming off the water, and every home in town gets the full run of Central Mass weather: cold, gusty winters and humid summers. New vinyl windows seal out drafts, never need painting, and help keep each room more comfortable year-round.

Window Styles for Shrewsbury Homes

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

Entry, Patio Sliding & Storm Doors

A patio door that sticks or lets in drafts is one of the most common requests we hear from Shrewsbury homeowners, especially in homes with a back deck. We install new patio sliding doors, steel entry doors and storm doors, each measured to fit your opening and sealed with fresh weatherstripping. See our full door replacement options.

How a Castle Install Works

First, a free in-home estimate. We measure every opening, check each frame and talk through styles and glass options with you.

On install day, our crew protects your floors and furniture, removes the old sashes and fits each new vinyl window into the existing frame. Because most of our installs are inserts, your interior and exterior trim stays in place. We only recommend full-frame replacement when an old frame is damaged. Most jobs are done in one day, and we haul away the old windows when we leave.
