Window Company in Fontana, CA
Juniper Windows & Doors is the windows-and-doors specialist inside the Relay Home Co. family, serving Fontana homeowners with replacement windows, new-construction window installation, and door replacement. Fontana’s mix of 1950s ranch homes, 1990s stucco tract housing, and new subdivisions north of the 210 means window and door work here spans everything from retrofitting original wood frames to installing impact-rated glass on newer builds. Whether it’s a single fogged slider or a full-home window swap, every Fontana job starts with a written price in hand before any work begins. Call (682) 281-2168 for a free estimate.
Why Fontana Homes Are Different
Fontana sits at the foot of the San Bernardino Mountains, and that geography shapes what happens to windows and doors here. It’s a warm, sunny Inland Empire climate – Fontana averages more than 280 days of sunshine a year – which means UV exposure on west- and south-facing glass is relentless. Window seals, weatherstripping, and vinyl frames age faster on those exposures than homeowners expect. We regularly see failed seals and warped sashes on homes along Sierra Avenue and in the older streets around Downtown Fontana, where original single-pane windows from the 1950s and 60s are still common. Fontana also gets the Santa Ana winds, which push through the Cajon Pass and rattle older doors in their frames. Homes in the north end of Fontana, near the foothills and Etiwanda area, catch more of that wind and also sit closer to the Wildland Urban Interface, which drives demand for impact-rated glass and tighter door seals. The housing stock is a patchwork: hardcoat stucco over wood framing on older homes, newer homes with larger window openings and sliding glass doors, and plenty of homes built during the 2000s boom that are now hitting the age where builder-grade windows show their limits. HOA expectations in Fontana’s newer master-planned communities also matter – several of the newer subdivisions along Duncan Canyon Road and Beech Avenue have design review rules that affect window frame colors and door styles, so any window or door project should start with a quick check of the HOA’s architectural standards.
Our Main Fontana Services
Three services make up the bulk of what Fontana homeowners ask us for. Each one gets its own page with local pricing, timelines, and details.
Window Replacement in Fontana
Replacing windows in Fontana often means dealing with older homes where the original frames have settled, stucco surrounds need patching, and the old glass is single-pane and barely insulating against Fontana’s summer heat. We handle full tear-outs down to the rough opening, replacement of rotted or sagging frames, and installation of new insulated glass units sized to the actual opening, not the original order sheet. Fontana’s south- and west-facing rooms benefit most from low-E coatings and a lower U-factor, which slows the heat that comes through the glass every afternoon. Window Replacement in Fontana covers what the work costs and how it’s done.

Window Installation in Fontana
New window installation in Fontana happens most often on additions, ADUs, and new homes where rough openings have been framed and flashed but the windows haven’t been set. It is different work from replacement: the openings are square and clean, the waterproofing is our responsibility from the first layer, and the job has to pass inspection before trim goes up. Fontana’s hot, dry summers mean we pay special attention to expansion gaps on vinyl and aluminum frames, because the framing moves slightly between 40-degree winter nights and 105-degree summer days. Window Installation in Fontana explains the full process and timeline.

Door Replacement in Fontana
Fontana door replacements run the range from front entry doors that have warped in the sun to rear sliders that stick after years of dust and Santa Ana wind. Older homes in Fontana frequently have non-standard door sizes – 30-inch and 32-inch entries, narrow patio doors – so off-the-shelf doors often won’t fit without reframing. We measure every door on site, address whatever the frame reveals, and set the new unit square and level so it closes without dragging. Door Replacement in Fontana breaks down costs by door type.
