  • Installing a replacement window near Seattle, WA

    Because of our volume purchasing agreements with replacement window manufacturers and our debt free company structure, our clients find that the bids they receive are very competitively priced. We also offer financing terms or deferred payments upon request. We provide free no obligation written estimates without the high pressure tactics common to the industry.

    The installation process is often the most overlooked component of a window replacement purchase. Unlike most companies who cut corners on labor or subcontract their work to outsiders, our long term salary employed installation teams take a true craftsman approach to their work. These differences become apparent in the visible look of your home. As one of the longest-operating independently owned construction firms in the state, we look forward to serving you!

    -- Einar Johanson, business founder and owner
