If your siding is cracked, warped, or fading unevenly, you are probably wondering what a full replacement will cost. The honest answer is that it depends on your home’s size, the material you choose, and how much of the old siding has to come off first. Here is what St. Louis homeowners can expect to budget for in 2026.
Average Siding Replacement Costs
Most homeowners pay between $9,000 and $20,000 for a full siding replacement on an average-sized St. Louis home, though the final number depends heavily on material.
- Vinyl siding: generally the most affordable option, often $7,000 to $14,000 installed
- Fiber cement siding: more durable and fire resistant, typically $14,000 to $24,000 installed
- Wood siding: higher upfront cost and more upkeep, often $16,000 to $28,000 installed
These ranges assume a standard two story home with straightforward removal. Homes with extensive trim work, multiple stories, or storm damage underneath the old siding will run higher.
What Actually Drives the Price
A few factors move the number more than anything else:
- Square footage of exterior wall space
- Material choice and thickness
- Whether the old siding needs to be removed or can be covered
- Condition of the sheathing and framing underneath
- Trim, corner posts, and detail work around windows and doors
St. Louis’s freeze and thaw cycles are hard on siding, especially older wood and aluminum products. If moisture has already worked its way behind the panels, your contractor may find rot or damaged framing once the old siding comes off. That is worth planning for financially before work begins.
Why Siding, Gutters, and Fascia Go Together
Siding rarely fails on its own. Poor drainage from clogged or undersized gutters is one of the most common reasons siding and the wood behind it start to fail early. If your gutters have been overflowing or pulling away from the roofline, it is worth having them inspected at the same time as your siding, since replacing siding without fixing the drainage problem behind it just sets you up for a repeat.

Getting an Accurate Number
Every home is different, and the only way to get a real number is a measurement and inspection. According to the National Association of Realtors, exterior projects like siding replacement consistently rank among the remodeling upgrades homeowners recover the most value from at resale, which makes it a worthwhile investment even before you factor in curb appeal.
