Webster Exteriors Inc recently installed Viwinco Cambridge windows and CertainTeed insulated siding on a home in Chesterfield near Baxter Rd. We installed windows and siding in 1993 for the same homeowners on their previous home. We are proud to have many repeat customers.

Viwinco Cambridge windows come with a lifetime warranty for glass breakage as well as standard lifetime warranties. The Cambridge features 15/16″ insulated glass, Low-E glass and Argon gas, as well as Viwinco’s patented “Tilt-N-Lock” system which allows for easy one-handed operation to tilt in the window for cleaning.

The siding is CertainTeed Cedarboards, which includes contoured foam for added insulation to your walls and noise reduction. Cedarboards are designed with a detailed wood grain texture to emulate the look of real wood siding. Vertical siding was installed on the front of the home.

All of our fascia is hemmed, with the raw edges turned under to prevent a corrosion line. We believe it is our quality and attention to detail that sets us apart from other companies.
