A craftsman-style St. Louis home with new board-and-batten and stone siding installed by Reliant Exteriors
Siding Replacement

Vinyl, LP SmartSide, and James Hardie — installed so the wall actually sheds water.

Reliant installs full-house and partial siding replacements across St. Louis and one hour beyond. House wrap, flashing, trim, and J-channel done to manufacturer spec — because siding installed wrong doesn't fail at the panel, it fails at the wall behind it. Backed by the 6-Year Reliant Guarantee.

Why siding work goes wrong.

Siding is the part of a house most people underestimate. The visible panel is the easy part. The work that determines whether the wall behind it stays dry — the substrate, the moisture barrier, the flashings, the details around windows and roof-to-wall transitions — is what separates a siding job that lasts from one that calls back.

Most siding callbacks aren't about the siding. They're about water that found a path past it. Our scope on every siding job is built around the same principle: get the water management right, then put the panel on.

We assess each home individually and tailor the install to the siding line you choose, the home's existing condition, and the manufacturer's installation specifications. What gets replaced, what gets reused, and where additional detail work is added gets documented in your written scope before any tear-off begins — and updated in writing if conditions change once we open the wall.

Three product lines, three trade-offs.

Vinyl

Lowest cost, fastest install, lowest maintenance. Color options are wide. Premium vinyl lines (.046+ thickness) are very durable; budget vinyl is thinner and shows ripples in heat. The right pick for most St. Louis retail jobs.

LP SmartSide

Engineered wood with a primed finish. Looks like real wood, takes paint well, holds up to impact better than vinyl or fiber cement. Mid-range cost. Excellent choice when curb appeal matters more than rock-bottom price.

James Hardie fiber cement

Cement-based, fire-resistant, very long service life. Heavier and slower to install (drives cost up). The premium option. Standard on higher-end remodels and many new-construction homes in St. Louis.

Mixed elevations

Many St. Louis remodels combine board-and-batten in gables with lap siding on the field, plus a stone or brick wainscot. We do the full design and color spec on a free in-home consultation.

Storm-damaged siding.

Hail damage to vinyl and engineered wood siding is real and often missed by carrier-side inspections that focus on the roof. We document siding damage on every elevation as part of a hail or wind inspection.

When a carrier scopes only a partial replacement, the question that decides what's actually achievable is: can the original panel still be sourced and matched? Siding more than a few years old has often been discontinued or quietly reformulated — what looks like the same product on the shelf no longer matches the panels still on your house.

When that's a real question on a job, we pull a small sample of your existing siding and submit it to ITEL Laboratories — an independent testing lab that identifies the manufacturer, line, and current availability of the panel. The lab report becomes part of the documented scope. (Full mechanics on the ITEL siding match page.)

Depending on what the report shows and the language in your policy, an unmatchable or discontinued panel can move the conversation from a patch repair to a full-elevation or full-house replacement under like-kind-and-quality or uniform-appearance provisions. We don't pull ITEL on every job — only when the scope is partial and a match question would change the outcome.

See the Hail & Storm Damage page for how the scoping side works.

FAQ

Common questions about siding replacement.

How long does a siding replacement take?

Most St. Louis-area full siding replacements take three to seven working days, depending on square footage, profile, and weather. Single-elevation repairs are usually one to two days.

What siding products do you install?

Vinyl (multiple manufacturers), LP SmartSide engineered wood, and James Hardie fiber cement. We install to each manufacturer's published specification so the product warranty stays intact.

Will my new siding match the old?

For full-elevation or full-house replacements, you choose the new color and profile. For partial repair after storm damage, the standard is "compatible materials" — when an exact match is not available because the original line has been discontinued, the documentation reflects that.
