Replacement Windows In Seabrook
Seabrook is our home town. The Window Source NH is a family-owned replacement window and door company. Our shop is right here at 779 Lafayette Road, on the Massachusetts line. For Seabrook homeowners, that means the company doing your windows is based right here in town. Our own local crew handles every job, start to finish.
Beach, Rivers And Grape Hill
Seabrook sits at the southern end of the New Hampshire coast. It is the first town you reach heading north on I-95 into the state. Seabrook Beach takes up the eastern end of town, along the Atlantic Ocean.
Inland, the land rises toward Grape Hill, the town’s highest point, whose summit sits just over the line in Salisbury. The Blackwater, the Browns River and the Hampton Falls River all drain toward Hampton Harbor. In the southwest corner, Lucy Brook runs to the Back River in Massachusetts.
Homes here range from year-round houses to places used for part of the year. At the 2010 census, some of the town’s homes were held for seasonal or recreational use. Each kind of house asks something different of its windows.
Windows For Salt Air And Ocean Wind
If you live near Seabrook Beach, wind off the water will find any gap in a tired window. Triple-pane glass is the strongest answer we offer.
The Harvey Homerun, from $699 installed, is our best value. It is a custom-built Harvey with triple-pane glass and a .18 U-value, the most efficient window we sell. The Gentek Series 9000, from $683 installed, is also triple pane, with a .22 U-value and the Energy Star Most Efficient rating.
Farther from the water, most homeowners do well with our best seller, the Harvey Classic, from $617 installed. It has fusion-welded frames, double-strength glass and a .24 U-value. Where the view matters most, consider the Harvey Slimline, from $545 installed. Its slim welded frame shows more glass, with a .29 U-value.
These prices are for a white double hung with basic installation. Grids and colors add. Harvey Windows + Doors is a New England manufacturer based in Waltham, Massachusetts, and our Harvey windows page has more on the brand. You can also compare every model on our double hung windows page.
Beyond windows, we install sliding patio doors from Harvey and Gentek, entry doors and vinyl siding. A bay or bow window can open up a room that faces the water or the street.

Our Neighbors Across The Line
