Visit the Custom Exteriors Pleasanton Showroom
See it. Touch it. Then decide.
Photos can't tell you how a fiberglass window compares to vinyl, what James Hardie siding feels like up close, or how an entry door actually swings and locks. Our Pleasanton showroom has full-size, working displays of every product we install, so you have real information before you commit to anything.

- No Subcontractors, Our Installers are Employees
We've been part of this community since 1997, and our showroom reflects that commitment. This isn't a big-box experience, it's a local one. Schedule an appointment, come in, take your time, ask every question you have, and leave with a clear picture of what's possible.
Why visit before you decide
A photo can't tell you what your hand can
You cannot accurately judge a window's weight, a siding panel's texture, or a door's finish quality from a picture on a website. That's what the showroom is for. Most contractors quoting your project don't have one, you're expected to take their word for it. We'd rather you didn't have to.
- COMPARE MATERIALS SIDE BY SIDE - Hold a fiberglass sash next to vinyl. See James Hardie's factory finish next to a field-painted sample. The differences that matter, weight, rigidity, finish quality, are obvious in person and easy to miss in a brochure.
- ASK QUESTIONS WITHOUT PRESSURE - No appointment required, no sales script. Walk in, look at what you want to look at, and talk to a design consultant only if and when you want to.
- MAKE A MORE INFORMED DECISION - Homeowners who visit the showroom report more confidence comparing our bid against other contractors — because they've actually seen what they're paying for.
What's in the showroom
Full-size displays of everything we install
We don't install a wide range of budget and premium options, we install three product lines, exclusively, and the showroom is built around them.
Infinity from Marvin windows & patio doors - Working, full-size displays of Infinity from Marvin's fiberglass windows and patio door configurations, sliding, French, folding, and multi-slide. Open them, close them, feel the hardware. Custom Exteriors is an Infinity Platinum Partner, Marvin's highest certification tier.
James Hardie fiber cement siding - Physical samples across James Hardie's ColorPlus Technology finishes and textures, so you can see the factory-applied finish quality up close, something no photo of a home facade can fully show.
ProVia & Therma-Tru entry doors - Door slabs, hardware, glass, and finish options from both brands side by side. Our design consultants are available to walk through the choices — profile, security hardware, glass style — as a design process, not a transaction.
Recognized By
When you're comparing contractors, third-party recognition gives you something to verify beyond what we say about ourselves.
