Built For Local Conditions

Energy-efficient upgrades for Lake Forest Park homes

Heavy tree cover keeps Lake Forest Park cool and damp for much of the year. That is hard on wood windows and decks, which is why rot-proof vinyl and fiberglass frames and composite decking make sense here. Larger windows or a new patio door can also bring welcome daylight into a shaded home.

Lake Forest Park homes are served by Seattle City Light, which has offered rebates on qualifying energy-efficiency upgrades. Programs and eligibility change, and often depend on how your home is heated, so ask us during your estimate and we'll help you look into what is currently available.
