Patio door replacement cost — Kent, WA
Last updated: September 24, 2026
What affects the price
When you call to discuss a new sliding door, the final cost depends on a few specific factors. First, consider the door material, such as vinyl, aluminum, or wood, as each carries a different price point. Size and configuration also play a role; a standard two-panel slider is more budget-friendly than a custom multi-slide system. We also look at the condition of your existing frame and whether any structural work is needed to ensure a smooth, energy-efficient install. Exact pricing confirmed free on the call.
