About aluminum siding estimates
Aluminum siding was the dominant siding material in the U.S. from the 1940s through the 1970s, and it's still manufactured today — mostly for repairs and additions on homes that already have it. It resists fire, rot, and insects, and unlike vinyl it won't crack in cold weather, though it can dent more easily and typically needs repainting every 10–20 years to keep its finish.

Aluminum Siding Cost Guide
Common questions about pricing and repairing aluminum siding.
Is aluminum siding still available to buy?
Yes, though it's far less common than vinyl today. Most aluminum siding sold now goes toward repairing or extending existing aluminum-sided homes rather than new construction, so matching your existing panel profile and paint color is often the biggest challenge, not availability itself.
How much does aluminum siding cost per square foot?
Installed, aluminum siding typically runs a rough U.S. national average of roughly $6–$9 per square foot combining material and labor — generally a bit more than vinyl but less than fiber cement. Custom colors and heavier-gauge panels cost more than standard mill-finish aluminum.
Can dented aluminum siding be repaired instead of replaced?
Small dents can sometimes be filled and repainted, but aluminum doesn't spring back like vinyl, so a badly dented panel usually needs to be replaced outright. Because older panel profiles can be hard to match exactly, many homeowners keep a few spare panels from the original installation for this reason.
Does aluminum siding need to be repainted?
Most aluminum siding needs repainting roughly every 10–20 years as the factory finish chalks and fades. This is a cost vinyl siding doesn't have, but it also means you can change your home's color without replacing the siding itself.
Tips for aluminum siding projects
If you're patching a section of existing aluminum siding, bring a sample panel to your supplier — panel profiles and paint colors from the 1960s–80s often don't match anything currently manufactured, and mismatched panels are visually obvious. Aluminum is fully recyclable, so leftover or removed panels can typically go to a scrap metal recycler rather than the landfill.
