Sliding patio doors in Mobile, Alabama
Two or more large glass panels; at least one glides on a track. For Mobile's older housing stock (64.8% of homes predate 1980), sliding patio door replacement is a common project — and in the ENERGY STAR Southern zone, the number that matters most is a low SHGC (≤ 0.23) to block solar heat.
Short answer
Sliding patio doors in Mobile typically cost $1,480–$4,930 installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Rebates & incentives in Alabama
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
Alabama's IRA Home Energy Rebates are administered by ADECA (Alabama Department of Economic and Community Affairs), which as of mid-2026 still lists the HOMES and HEAR programs as under development with no confirmed date for when households can access rebates. If and when they open, windows would generally qualify only through the whole-home HOMES modeled-savings pathway rather than as a direct rebate. Confirm current status with ADECA before relying on it. See our Mobile guide for the full program list.
