Is $90k for a siding job on a one-story house actually normal?

That price is absolutely absurd for a 2,200 square foot home, and everythign about this interaction screams door-to-door scam. $90k isn't just high; it's astronomical for a house that size in the PNW, even with the current cost of materials. These guys rely on high-pressure tactics and fake discounts to catch homeowners off guard, and they're hoping you don't know any better.

There is no way for a guy standing on your lawn to know if you have a moisture barrier or not unless he's literally pulling boards off the wall. Building code in the early 2000s absolutely required a weather-resistive barrier, whether it was Tyvek or felt paper. The fact that he's claiming it’s missing without any destructive testing is a massive red flag. He’s looking at wood trim rot—which is common maintanence after 20 years—and trying to parlay that into a full-house teardown.

If your wood trim is rotting, just hire a local siding specialist to replace those specific sections with **fiber cement trim** or PVC. You don't need to strip the whole house because of some soft corners on your window frames. Hardie siding itself is incredibly durable. If it isn't buckling, cracking, or showing signs of delamination, it’s doing its job. Gaps in the caulk are also just part of the maintenance cycle; you scrape out the old stuff and put in fresh high-grade sealant.

For a house your size, a full replacement with new Hardie boards and a proper wrap shoud realistically land in the $25,000 to $40,000 range. $90k is basially a "sucker price" meant to see if you'll bite. Tell that guy to get lost and find a reputable local contractor who has a physical office in your area to give you a real assessment. If you’re really worried, pay a home inspector a few hundred bucks to do a moisture probe test. It'll save you eighty-nine thousand dollars.

That $90k price is terrifying. I'm actually looking into replacing my patio doors right now and the salesman tried to pull the same "rot" story on me. If you do just replace the trim around the side door like suggested, does that fix the seal for the door itself? I’m worried about water getting behind my threshold if the casing is allready soft. Is it common for these guys to use the "missing moisture barrier" line just to get people to buy a whole house package instead of just the entryways they actually need?

Since you're worried about that side door threshold, check the pan flashing. If the builder actualy skipped the moisture barrier, you'd see water damage on the interior drywall or the subfloor under the door sill by now, especially in the PNW. If the trim is just soft, it's usually just splash-back from the ground or poor caulking on the brickmold. You can swap that for PVC trim for a few hundred bucks. Don't let them convince you the whole rough opening is compromised without seeing the jack studs. That $90k quote is basically a 'go away' price or a predatory markup. You could literally replace every exterior door in your house with high-end fiberglass for a fraction of that.

That $90k quote is definatly a "go away" price or a total scam. If you're seeing rot on the door trim specifically, check for a drip cap above the casing. A lot of times, builders forget that tiny piece of metal flashing, and water just runs behind the trim and rots the wood from the inside out. I had a similar guy stop by last summer. They love to get people paranoid about "unseen damage" to justify a full teardown. If the siding is Hardie, it's basically concrete. Unless it's falling off the wall, you're fine. Just grab a couple tubes of OSI Quad and hit those gaps yourself on a dry day. It’ll cost you twenty bucks instead of ninety grand.

Check the side door's brickmold specifically. If the rot is only at the bottom, it's likely 'wicking' from the threshold. alot of those 2000s builds didn't use a sill pan, so the wood trim just sits in a puddle every time it rains. If you’re pulling the trim, see if the door jamb itself is soft. You can usally swap out just the exterior casing for PVC without touching the siding.

Also, look for the gap between the siding and the door casing—there shold be a 1/8 inch expansion gap filled with a high-quality sealant. If they butt the Hardie tight against the door trim, that's where your moisture issues actually start.
