Blyth & Shearn Inc. - Loewen Windows

Blyth & Shearn Inc. is an independent, full-service window and door company dedicated to offering and installing the best possible window and door products for new construction, renovations, and replacements.

Blyth & Shearn Inc. Unlike a conventional lumberyard, our focus is concentrated exclusively in the window and door area. This approach enables Blyth and Shearn Inc. to meet the challenges of demanding consumers. We also have that extra expertise that a mass marketer cannot provide. Whether you are building a new, energy-efficient home or renovating or replacing windows, our dedicated, professional staff has the knowledge to answer your questions.

We take pride in our installation program. Our thoroughly trained employees also pride themselves on the quality of our products and the quality of their installations. To fully serve our customers, we offer everything from parts to large commercial installations. Since we are a privately owned company, we are not compelled to sell you a product that is not in your best interest. We represent only good, strong companies who have a record of quality and service.

Owners William Blyth and Robert Shearn have been helping people beautify their homes with quality windows and doors for more than 35 years. Blyth and Shearn Inc. uses commercial-grade sealant for all installations. You also have a choice of fir, pine, or oak interior window trim. We have fully insured and experienced factory-trained installers.
