Royal Vinyl Siding by Westlake for St. Louis Homes

Royal Vinyl Siding is Casey Exteriors’ original siding line: a low-gloss cedar woodgrain vinyl engineered to withstand hurricane-force winds, resist fading and never need painting. It comes in three lines, Estate, Residential and Woodland, each built on Westlake’s Double Lifetime Warranty. We measure, install, seal and trim every job ourselves.

Why we install Royal Vinyl

Style That Stands Out, Built to Last

Casey Exteriors has installed Royal Vinyl Siding since day one because it gives St. Louis homeowners a genuine wood look without a wood siding’s upkeep, engineered to shrug off Missouri’s wind, hail and humidity swings.

The install matters as much as the siding. Every Royal Vinyl job is measured, installed, sealed and trimmed by Casey Exteriors, with cleanup and haul away included.

Our siding lines

Three Royal Vinyl Lines, One Honest Comparison

Every home and budget is different. We carry three Royal Vinyl Siding lines so you can pick the right balance of style, wind rating and price. At your estimate we will price all three side by side for your exact home.

Premium

ROYAL ESTATE

Westlake’s flagship Royal line: 50 years of engineering behind its most premium exterior finish.

Most Popular

ROYAL RESIDENTIAL

The workhorse Royal Vinyl line: broad color choice, proven wind performance, at Casey’s most requested price point.

Woodgrain Premium

ROYAL WOODLAND

Casey’s highest wind-rated Royal line, with the deepest color range for homes that want a bolder look.

The premium choice

Royal Woodland: Our Highest Wind-Rated Siding

For homeowners who want the boldest color range and the strongest wind performance in the Royal Vinyl lineup, Royal Woodland is Casey’s top recommendation. Its premium and Dark Colorscapes shades hold their color under UV exposure, and it’s rated to withstand hurricane-force winds up to 200 mph.

The warranty

Westlake's Double Lifetime Warranty

We would rather you know the details up front. Here is what Westlake’s Double Lifetime Warranty covers, in plain English.

The fine print, in plain English
  • Ask us for Westlake's full written warranty document; the exact term, transferability and registration requirements are set by Westlake, not Casey.
  • Wind ratings apply to specific profiles installed to Westlake's specifications; actual coverage depends on your home's exposure and installation.
  • Altering or painting the vinyl can affect warranty coverage.

Our part: Casey Exteriors backs the installation with our own workmanship warranty.
