Spencer Construction

Einar Johanson Insulation and Glass sells and installs replacement windows and doors in the Greater Seattle area. We provide free, no obligation, written estimates and offer exceptional financing terms or deferred payments upon request. 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. 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!
