Built For Local Conditions

Energy-efficient upgrades for Mukilteo homes

A west-facing view comes with weather: wind-driven rain in winter and strong afternoon sun in summer. Low-E glass, careful flashing and frames that won't corrode in salt air keep a view window performing, and a low-profile deck railing keeps from blocking what you came for.

Mukilteo homes are served by Snohomish County PUD, 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.
