Northborough has kept much of its small-town feel even as it grew into a busy suburb between Worcester and MetroWest. Its center along Route 20 and the Assabet River still has antique homes and Victorians, and old mill areas like Chapinville recall the town’s early industry. As the town shifted from farms to neighborhoods in the second half of the 1900s, capes, ranches, split-levels and colonials filled in the land on either side of Route 20 and I-290.
Castle “The Window People” of Massachusetts helps Northborough homeowners with energy-efficient vinyl windows and new entry, patio sliding and storm doors, all backed by the Castle Lifetime Guarantee.
Why Northborough Homeowners Replace Their Windows
In Northborough’s antique homes, the usual story is single-pane sashes, loose storm windows and frames that have been painted shut. In the mid-century capes and ranches, early replacement windows are often worn out. And in the colonials built in the 1970s through the 1990s, original builder-grade windows are showing their age with foggy glass, broken balances and air leaks around the sash.
Northborough winters bring snow, ice and wind, and summers can be humid along the river. New vinyl windows seal out drafts, help each room hold its temperature and never need scraping or painting.
Window Styles for Northborough Homes
All of our replacement windows are vinyl, with ENERGY STAR certified options available depending on the package you choose.
- Double-hung windows fit the colonials and capes found all over town and tilt in for easy cleaning.
- Sliding windows suit ranches and split-levels with wide openings.
- Bay and bow windows add light and space to a living room.
- Casement and awning windows are easy to crank open over a sink or counter.
- Picture windows frame a backyard view.
- Hopper and specialty shapes take care of basements, bathrooms, half moons and arches.
Many Northborough homes have a mix of window sizes from additions and updates over the years. We measure every opening on its own, so each new window fits its frame instead of a one-size-fits-all approach.
Doors for Northborough Homes
We replace worn front doors with steel entry doors that seal and lock tight, swap sticky sliders for patio sliding doors that glide easily, and add storm doors that protect your entry and let in a breeze. Every door is measured to fit. Learn more on our doors page.
How We Install
We start with a free in-home estimate. We measure each opening, check the frames and give you a straightforward plan.
Most of our Northborough installs are inserts that keep your existing interior and exterior trim, so the job stays neat and your home keeps its look. If an old frame is damaged, we’ll recommend full-frame replacement for that opening. Most jobs are finished in one day, and we take the old windows away when we’re done.
