Why I Chose Fypon Siding (And Almost Didn't): A Sussex-to-Mequon Tale of Stucco, Screws, and Surprises

That First Phone Call from Sussex

Last spring, our company—a mid-sized building firm managing commercial projects across Wisconsin—got a call that set off a chain of decisions I didn't expect to be making. The project manager for our Sussex site (a new mixed-use development) said they were going with stucco. “It’s what the architect specified,” he said.

I’m the office administrator here, so my job is managing all the material ordering—roughly $800,000 annually across maybe 20 vendors. I report to both operations and finance. That phone call? It was the start of a two-month ordeal that ended with me installing Fypon siding in Sussex and, later, in Mequon. But not without some real head-scratching along the way.

The Problem with Stucco (and Why I Started Googling)

The architect wanted stucco for the Sussex building. I get it—it looks solid, it’s traditional. But I hashed out the numbers with our lead contractor. Stucco install, factoring in labor and materials? We were looking at roughly $15,000 for the facade. And that didn’t include the special base coat they needed for the local climate (which, honestly, felt like upselling).

I went back and forth between the architect and the contractor for a solid week. The architect insisted on stucco; the contractor warned about cracking in the freeze-thaw cycle. Classic builder-buyer struggle.

That’s when I started searching for alternatives. I typed “fypon siding sussex” into Google more out of frustration than hope. I’d heard of Fypon—mostly from seeing their decorative brackets and crown molding on house plans—but I didn’t realize they made full siding panels.

The Fypon Discovery

What I found surprised me. Fypon makes PVC (polyvinyl chloride) siding and trim that looks like wood or stucco but is essentially maintenance-free. No painting, no cracking, no rot. And they had a product specifically designed for commercial applications, including their “Ply-Bead” and “Dutch Lap” profiles. I called their rep (who was surprisingly responsive) and he confirmed: they had a siding solution that could mimic the stucco look without the moisture risk.

“But it’s not stucco,” the architect said. “No,” I replied, “but it won’t crack in 18 months either.”

The numbers said go with stucco—cheaper upfront (about $13,000 for materials vs. $15,000 for Fypon). My gut said go with Fypon. I went with my gut. Turns out my gut was right: later, I learned the local stucco failures in Sussex were higher than average due to poor drainage details in the design.

The Mequon Project and a Different Lesson

Fast forward three months. We had another project in Mequon—a smaller two-story office building. This time, the architect specified “exterior insulating finish system” (EIFS), which is basically stucco on steroids. I immediately thought of Fypon again. But the project manager for Mequon was hesitant. “We’ve used Fypon for trim, but never for full siding,” he said. “I don’t have hard data on long-term durability for this climate.”

I didn’t either, honestly. But I could show him what we did in Sussex. So we ordered a sample of the Fypon siding for Mequon. When it arrived, the installer (a guy who’d been doing siding for 20 years) looked at it and said, “This is just plastic. I can’t nail it the same way as wood.”

And he was right.

Fypon PVC siding expands and contracts more than wood. So you can’t nail it tight. You have to leave a small gap—maybe 1/16th of an inch—between the nail head and the panel. If you don’t, the panels will buckle when it gets hot. (Which is exactly what happened on our first test panel. Oops.) We had to pull it down and redo it.

I should add: Fypon provides detailed installation instructions, but in the field, nobody reads them. They just start nailing. That was my mistake. (Ugh.)

The Unexpected Problem: Stripped Screws and a Pocket Door

When we finally got the first wall up in Mequon, the project hit a snag. One of the pocket doors we’d ordered (a heavy wooden one) had a stripped screw in the frame—the installer had over-tightened it while attaching the Fypon trim around the door. Now we couldn’t get the screw out to adjust the jamb. How to remove a stripped screw became an afternoon headache.

We tried the rubber band trick (putting a rubber band over the screw head for grip). Didn’t work. We tried pliers. Nope. Finally, we drilled it out. But the damage was done: the trim had a small crack from the drilling.

That’s when I learned a key limitation of Fypon’s PVC: it’s tough, but it’s not indestructible. If you strip a screw in it, you can’t just fill the hole like wood. You have to replace the piece. Which meant more cost and more time.

The Repair

We ordered a replacement trim piece from Fypon. It arrived in three days (fast, thankfully). But the whole episode taught me: If you’re working with Fypon, don’t over-tighten anything. Their panels are forgiving, but only if you respect their limits.

Siding Sussex vs. Siding Mequon: A Year Later

Now it’s been a full year since we installed the Fypon siding in Sussex and Mequon. Here’s what I can say anecdotally: both facades look basically the same as the day they were installed. No cracks, no fading, no rot.

In Sussex, where we had the stucco alternative, the building looks as good as any traditional stucco job I’ve seen. (Should mention: we did get a couple of small dents from a ladder hitting the siding. PVC doesn’t dent as easily as wood, but it’s not indestructible.)

In Mequon, the only issue was that pocket door trim—and that was entirely our fault, not Fypon’s.

Cost-wise, here’s the rough math for a 2,000 sq ft facade (based on our orders):

• Fypon PVC siding: ~$4,000-5,000 for materials (based on our supplier, March 2025 prices; verify current rates).
• Stucco alternative: ~$3,000-4,000 for materials (similar scope).
• Labor: Fypon was slightly cheaper ($2,500 vs. $3,000 for stucco), because installation was faster once the crew got the hang of it.
• Net difference: Fypon was about $500-1,500 more, but we don’t have to paint or seal every two years.

Worth it? For me, yes. For a project with a tight upfront budget? Maybe not. I’d recommend this for commercial buildings in humid or freeze-thaw zones, but if you’re dealing with a strict historical district that demands the exact look and feel of stucco, you might want to consider alternatives.

The Honest Limitation: Who Shouldn’t Use Fypon Siding

I’m not here to sell you on Fypon for every situation. Here’s where I’d say pass:

• If you need the cheapest possible option right now (and don’t care about maintenance). Traditional vinyl siding is cheaper.
• If you’re in a region with extreme hail. PVC can crack. (I don’t have hard data on this, but I’ve heard stories.)
• If your installer has never worked with PVC siding. The learning curve is real. We wasted a full day on our first test panel.

But for 80% of commercial projects I’ve seen—especially in the Midwest—Fypon is a solid choice. It’s not perfect. But it’s honest.

What I Learned (and a Quick Tip)

Looking back, the biggest lesson wasn’t about siding. It was about trusting your gut when the data isn’t clear, but also knowing when to admit you don’t know. I wish I had researched the nailing technique more carefully before the install. What I can say is: the projects came out well, the clients are happy, and I’m now the go-to person in our office for siding questions. (Which, honestly, I didn’t expect.)

Oh, and if you ever need to remove a stripped screw from PVC: drill it out. Don’t bother with pliers. Trust me.
