Window Company in San Antonio, TX
Juniper Windows & Doors is a window company serving San Antonio, TX, where the housing stock and climate demand a more careful approach than most Texas markets. The city’s mix of late-1800s limestone and adobe homes, 1940s-50s steel-casement era houses, and sprawling 1970s-2000s brick veneer suburbs means every job runs into a different set of rough openings, foundation movement, and frame conditions. We work with eight product lines so the right window or door is never a compromise, and every job gets a written price before anything starts. Call (903) 488-7019 for a free estimate.
Why San Antonio Homes Are Different
San Antonio sits on expansive clay soils that swell and shrink with rain and drought. That movement shows up as shifted foundations, and shifted foundations mean window and door openings that are no longer square. In established neighborhoods like Monte Vista and King William, we routinely see wood-framed bungalows and stone homes where the original double-hung windows have settled into their openings at angles that make standard replacements a bad idea without custom flashing and shims.
Then there’s the heat. San Antonio’s summer sun and high UV break down window seals faster than most cities, which is why fogged insulated glass units are a constant call across the metro. Sudden downpours and the occasional hailstorm mean exterior doors and windows need robust flashing and impact-resistant glazing, not just a clean caulk line. In older neighborhoods near Fort Sam Houston and Alamo Heights, original steel casement windows from the 1940s and 50s are often rusted shut or missing operators entirely, and those replacements take real carpentry skill, not a drop-in retrofit.
Our Main San Antonio Services
Most San Antonio homeowners reach out about two things: energy-wasting windows that need replacing and doors that no longer close, seal, or lock properly. Each service has its own San Antonio page with local detail and pricing.
Window Replacement in San Antonio
Replacement work in San Antonio usually means pulling out failed aluminum or single-pane windows and rebuilding the opening before the new unit goes in. On 1970s-1990s brick veneer homes, the original aluminum frames are often corroded at the corners, and the rough opening behind them needs new flashing and insulation before a new window can perform. We regularly replace fogged builder-grade units in Stone Oak and Helotes, but we also handle steel casement retrofits in older neighborhoods near Fort Sam Houston. Every replacement gets a written price first. See Window Replacement in San Antonio.

Window Installation in San Antonio
New-build and addition window installation in San Antonio comes with its own set of code requirements, especially around egress and impact ratings on the city’s warmer side of the energy code. On older adobe and stone homes, we often install flanged windows into thick walls where the rough opening varies by an inch or more from corner to corner. Clay soil movement means we square and shim every opening before anchoring, because a plumb install on opening day can look like a bowing frame a year later if it’s rushed. See Window Installation in San Antonio.

Door Replacement in San Antonio
Entry doors in San Antonio take direct sun on the west side of the house, which warps solid wood doors and fades painted steel ones faster than homeowners expect. We replace them with reinforced, impact-rated entry systems from brands like Therma-Tru, and we reframe the opening when foundation movement has thrown the hinges out of line. Sliding glass doors in 1970s-1990s brick homes are often the biggest air leak in the house, and swapping them for a properly sealed modern unit changes the energy bill more than most window projects. See Door Replacement in San Antonio.

Our price gets locked in writing before any work starts, so the number on the quote is the number on the invoice.
