Fiber cement siding comes with a manufacturer warranty. Coat it with the wrong product and that warranty is gone — along with the siding.
That’s the situation we walked into on a renovation and garage addition in Blowing Rock. A previous contractor left the job with unfinished work across the punch list and, more seriously, interior paint applied to the exterior of the home.
Why that matters more than it sounds like it should:
Exterior paint is formulated for a job interior paint was never designed to do. UV inhibitors keep it from chalking in direct sun. Mildewcides handle the moisture that comes with mountain humidity and long wet stretches. Flexible resins let the film stretch and contract as siding moves through freeze-thaw cycles — and in Blowing Rock, Boone, and Banner Elk, that movement is constant from fall through spring.
Interior paint has none of those properties. It sits on the surface and releases.
What we found and what we’re doing:
→ The coating peels off the Hardie board by hand
→ Pressure washing was tested as a salvage option
→ Sherwin-Williams reps were brought in to review alternatives to removal
→ The fiber cement manufacturer will not honor the warranty on improperly coated board
→ Full siding replacement is underway
→ Electrical and plumbing corrections are included in the scope
If you’re hiring a general contractor in Western North Carolina, two things protect you:
Ask for product specifications in writing before work begins — siding, paint system, roofing, windows. Manufacturers publish required finishes and installation methods, and anything outside that spec can void coverage on materials that were sound when they arrived on site.
And keep a written record from day one. Dated photos, texts, and emails cost nothing while a project is going well, and they matter enormously if it stops going well.
This home is getting corrected properly. That’s the job.
If you’re living with work that was left unfinished or done wrong, send us a DM with photos and we’ll schedule a call to walk through options.
