Window Company in Castle Hills, TX
Juniper Windows & Doors is the window and door specialist for Castle Hills, TX, and we build every quote around one number: a written price before any work starts. Castle Hills homes were mostly built between the 1950s and 1970s, which means we spend a lot of time replacing original aluminum single-pane windows, corroded sliding glass doors, and hollow-core entry doors that never stood a chance against Texas heat and hail. If you need a straight answer on what new windows or doors cost in Castle Hills, call (903) 488-7019 and we’ll walk you through it.
Why Castle Hills Homes Are Different
Castle Hills’s housing stock is overwhelmingly mid-century ranch and traditional single-family homes from the 1950s and 1960s. That matters because the window openings are often narrow by modern standards, the original aluminum frames sweat and corrode in humid summers, and many still have single-pane glass that turns an air-conditioned living room into a greenhouse by 3 p.m. in July. The hailstorms that roll through San Antonio in spring are just as hard on those old frames, which is why impact-rated glass has become a standard recommendation here.
There’s another Castle Hills-specific detail older installers know: some original aluminum frames were sealed with caulk that contained asbestos, and pulling those frames without checking first creates a hazard. Every job starts with that inspection. On the door side, decades of sun exposure have warped and faded wood entry doors, and the sliding glass doors from the 1960s rarely seal properly anymore. The right retrofit here isn’t about aesthetics alone; it’s about getting a window or door that can actually hold a seal when temperatures climb past 95°F.
Our Main Castle Hills Services
Castle Hills homeowners most often call us for two things: pulling out old aluminum windows that leak air and replacing doors that no longer close squarely. Below are the three services we handle in Castle Hills, each with its own dedicated page.
Window Replacement in Castle Hills
Most replacement work in Castle Hills involves removing original 1950s and 1960s aluminum frames and putting in energy-efficient units sized to the existing openings. We check for asbestos-containing caulk around old metal frames before any pull, and we spec glass that handles Castle Hills heat without distorting. You’ll see a written line-item price before we order anything. Window Replacement in Castle Hills
Window Installation in Castle Hills
New construction, additions, or full gut renovations in Castle Hills get a different approach: we work from rough openings and coordinate with the framing schedule. Installation here often calls for impact-rated products because of spring hail exposure, and we’ll talk through U-factor and Solar Heat Gain Coefficient in plain language so you know exactly what the glass will do in August.

Door Replacement in Castle Hills
Castle Hills entry doors have usually been through forty or fifty Texas summers, and the telltale signs are a door that rubs the jamb at the top, sunlight visible around the weatherstripping, or a lock that no longer lines up. We replace with Therma-Tru and ViewLux options that hold their alignment and seal. Every door quote includes the full install, hardware, and a written price before the first screw turns.
