    Replacement Window Installation

    The installation process is often the most overlooked component of a replacement window 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. 

    Window Replacement Cost

    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 provide free no obligation written estimates without the high pressure tactics common to the industry.

    As one of the longest-operating independently owned construction firms in the state of Washington, we look forward to serving you!

  • Einar Johanson, Owner

    "There is a difference - a BIG difference - between a quality window and a low-bidder window. Cheap windows and untrained installers just aren't up to the job. Since 1957, we've operated with a 100% customer satisfaction policy."
    -- Einar Johanson, business founder and owner

    "Johanson's company...is revered in the Seattle area and is one of the longest-operating independently owned construction firms in the state... a true treasure, that man."  ...Read More

  • No High Pressure Window Sales

    Our in-home estimators are not allowed to use high pressure sales tactics common to the industry. They are paid in such a way that they don't have to. They simply measure your window and door openings, show you the options available and provide a written quote for your consideration.

    This is one of the reasons our many clients continue to write positive reviews about our company on Porch, Yelp, Angie's List, Google and other 3rd party review sites. Check out our Reviews Page to read more. 

  • Experienced Craftsmanship

    Our experienced window and door installers have been with our company for many years. You can expect them to come on-time,  treat your home as if it were their own, do a professional installation, and clean up after themselves when the job is done, ensuring your total satisfaction. 

    You can relax, knowing you are hiring one of the the longest-operating, fully licensed, bonded and insured construction firms in Washington State. License # EINARJ1072B5
