Living in Westlake Hills? Your million-dollar home has 40-year-old siding and nobody's talking about it
Real talk for Westlake Hills homeowners specifically:
You live in one of the most beautiful and most expensive neighborhoods in Texas. Live Oaks everywhere, Hill Country views, the whole thing. Median home values in 78746 are genuinely eye-watering. Congratulations, seriously.
But here's the uncomfortable question nobody's asking at those neighborhood cocktail parties: your house was probably built in the 70s, 80s, or 90s. Which means the original siding on your seven-figure home is likely 30-50 years old.
And in Texas, siding does not last 30-50 years.
If your home still has any of the following, this is your PSA:
→ Original hardboard siding (delaminating and swelling right now) → Original wood siding (rotting where the sprinkler system hits it every day) → First-generation vinyl (warping, fading, becoming brittle) → Anything showing paint that won't hold, gaps at corners, or that "chalky when you touch it" thing
Here's what makes Westlake Hills different from just about anywhere else:
Wildfire adjacency. You live next to actual Hill Country brush. The stunning mature vegetation you moved here for is, ecologically, wildfire fuel during a dry summer. Wood and vinyl siding are combustible. Fiber cement is not. In a fire-adjacent neighborhood, this isn't a small detail.
The property value calculation is completely different. In a $400k home, tired siding drops the value maybe 5%. In a $2M home, tired siding can cost you 6 figures at sale. Doing this project right isn't a lifestyle choice — it's asset preservation.
Your hillside site makes everything harder. Sloped lots, tight staging, longer material runs, limited street access. A cheap contractor who's never worked in this specific terrain will create chaos in your driveway and your neighbors' driveways. Ask me how I know.
The house-to-substrate connection is where money hides. When 40-year-old siding comes off, the sheathing underneath often has hidden rot. A real contractor inspects for this and prices it honestly. A cheap contractor discovers it on day three and hands you a $12,000 change order.
Material reality for high-value Westlake Hills homes:
→ James Hardie fiber cement is basically the default answer for this neighborhood → 30-50 year lifespan, non-combustible, engineered for Central Texas climate specifically → Comes in premium profiles that actually match the architectural character (Cedarmill, smooth, board-and-batten, factory-finished ColorPlus) → Elite Preferred Contractor certification exists because installation quality determines everything
Cost-wise, Westlake Hills siding replacement typically runs $20k-$60k+ depending on home size, story count, architectural complexity, and what they find in the substrate. The high end reflects real premium work on a real premium home — not overcharging.
And obligatory reminder: Texas has NO state contractor license. So you're doing your own vetting. Insurance, BBB accreditation, James Hardie Elite certification, real references you can drive by, itemized written scope. The cheap quote is cheap for exactly the reasons you'd expect.
Anyway, if you want the actual full breakdown for Westlake Hills specifically — hillside considerations, wildfire angle, HOA notes, cost realities — I came across this guide for Westlake Hills siding that lays out the specifics for the neighborhood. Worth reading before you take quotes from randos.
Take care of the house. It's the biggest asset you own.
