Meet the Team - Juniper Windows Santa Clarita

Meet the Santa Clarita Team Behind Juniper Windows Santa Clarita

We’re a local crew that has spent years working on Santa Clarita homes, from Valencia paseos to Canyon Country hillsides. What unites us is simple: we show up when we say we will, we give you a written price before any work starts, and we stand behind every install for 365 days. No exceptions. Sean Mackey runs the operation, but the people who measure, carry, seal, and trim your windows and doors are the ones you’ll see most. Here’s who we are.

Our People

Sean Mackey, Owner

Sean founded Juniper Windows Santa Clarita in 2001 as part of the Relay Home Co. family. He’s the one who insists on the 365-Day Done Right Promise being in writing on every single project, and he answers the phone when you call. Sean talks the way he works: straight. He’ll tell you exactly what a low-e coating does to your summer cooling bill in Valencia, then admit he’s sealed more than one gap with a product his supplier still refuses to name publicly. You’ll find him on job sites most mornings, not hiding behind a desk.

Mike R., Lead Technician

Mike has been setting windows and doors for 19 years, the last 11 of them here in Santa Clarita. He’s our go-to for impact-rated glass installs, the PGT and CGI lines especially, and he knows how wind loads differ between Saugus and Castaic better than most engineers we’ve met. Mike is the one who walks new techs through flashing details and sill pan work until it’s muscle memory. Off the clock, he’s rebuilding a 1968 Mustang, and he claims the patience required for window trim and carburetors is the same skill. We don’t argue.

Danielle T., Service Coordinator

Danielle is the voice on the other end when you book with us, and she’s the reason our live phone answer actually holds up. She’s been with Juniper for 7 years and keeps every job on schedule, every permit pulled, and every before-and-after photo sent to the homeowner with the digital invoice. Danielle knows the product lines cold, from ES Windows to Therma-Tru, so when you call with a half-remembered frame size and a vague description of a door, she’ll figure out what you actually need. Her desk has a small juniper plant on it, a nod to the name and to the fact that it survives everything.

Chris V., Senior Installer

Chris joined us 8 years ago after running his own handyman outfit in Newhall, and he’s the reason our caulk lines look like they were done by someone with a grudge against gaps. He specializes in door replacement, especially Therma-Tru entry systems and ViewLux patio sliders, and he’s background-checked and uniformed on every job just like the rest of the crew. Chris is the first to volunteer when a job runs long, and he packs the truck like a Tetris champion. He once measured a 1930s ranch in Stevenson Ranch where not a single opening was square, and he didn’t complain once. We checked.

One Standard, Every Job

Every Juniper location is independently owned and operated, and Santa Clarita runs on The Relay Standard. That means you book in a tap, you get a live arrival time you can track, before-and-after photos of the work, a written price in your hands before anything starts, and a digital invoice at the end. No estimate that becomes a surprise. No crew that disappears after the check clears. The 365-Day Done Right Promise covers parts and labor in writing for a full year. If we missed something, we return at no charge and fix it. That’s the only way Sean has run this crew since 2001, and it’s not changing.
