AfterWindow Company in Union City, CA
Juniper Windows & Doors is the window and door specialist for Union City, CA, handling replacement and installation work with one rule that never bends: a written price before a single screw turns. Union City’s housing stock runs from 1960s ranch homes in areas like Alvarado to newer builds up in the hills, and the salt-tinged bay air plus hot summer afternoons off the East Bay hills mean windows and doors take a beating here. If you’re pricing new windows or a replacement front door in Union City, call (682) 281-2168 and we’ll give you a real number in writing.
Why Union City Homes Are Different
Union City sits close enough to San Francisco Bay that windows facing west get a steady dose of marine air, and far enough inland that summer temperatures routinely push into the 80s and 90s. That mix accelerates seal failure in older double-pane units. Homes built here before the mid-1980s frequently have aluminum frames with single-strength glass, which means condensation between panes, frames that sweat in winter, and drafts you can feel from across a room.
The housing stock is a patchwork: 1960s and 1970s tract homes in the Alvarado and Decoto neighborhoods, mid-century ranches with wide picture windows, and two-story builds from the late 1990s and 2000s scattered east toward the hills. A lot of these homes still carry their original windows. When a 40-year-old aluminum slider finally gives out, the opening is rarely square, which is why our Union City jobs often include reframing the rough opening, not just swapping glass.
Terrain matters too. Homes on the eastern slope catch stronger afternoon sun and bigger temperature swings than homes down near the flats, and we spec glass accordingly – lower solar heat gain coefficients for west- and south-facing exposures, and impact-rated options where wind exposure is higher near open corridors.
Our Main Union City Services
Three jobs make up nearly everything we do in Union City: replacing tired windows, installing new ones in additions or remodels, and swapping out entry or patio doors.
Window Replacement in Union City
Replacing windows here usually means pulling out failed aluminum or builder-grade vinyl and putting in modern units that actually seal. We see a lot of fogged glass on the west-facing walls of Decoto homes, and plenty of original 1960s sliders in Alvarado that no longer lock properly. On older Union City homes, replacement often involves correcting framing around the opening before the new unit goes in. Window Replacement in Union City covers what we remove, what we install, and what it costs.
Window Installation in Union City
New construction and addition projects in Union City need windows installed to current California Title 24 energy code, which means specific U-factor and solar heat gain requirements based on climate zone and window orientation. We work directly with your general contractor or frame-to-order for direct installs, and we coordinate inspections so the permit process doesn’t stall. Window Installation in Union City walks through specifications, lead times, and what installation day looks like.
Door Replacement in Union City
Front doors on Union City homes face west sun in the afternoon and bay breeze year-round, so faded finishes and warped slabs are common. Entry doors, patio sliders, and French doors all come up in Union City neighborhood after neighborhood. A replacement door has to fit the existing rough opening, seal tightly, and hold up to daily use. Door Replacement in Union City covers material options, threshold details, and pricing.

What pushes price up in Union City is the age of the house: older openings that need reframing, rot repair at the sill, or a Title 24 energy upgrade add labor and materials to the job. What doesn’t push price up is us taking the work: every project gets a written price before anything starts, and we don’t adjust it at the door.

Yes, to a degree. West-facing exposures near the bay carry more moisture and salt air, which wears out seals and hardware faster than inland exposures. We spec frame and glass packages accordingly, and we’ll explain the reasoning in your written quote.
We pull permits and schedule inspections for window and door work that requires them, and we handle the paperwork end to end. If your job needs a Title 24 energy compliance check, that’s included in our scope so you’re not chasing inspectors yourself.
