Why Upland Homes Are Different
Upland’s housing stock runs from Craftsman and Spanish Colonial bungalows built between 1900 and 1930 to sprawling 1960s and 1970s ranch houses and newer tract developments. The older homes, particularly those near downtown, often still have original single-pane wood sashes in non-standard openings. When we replace those, we’re not just swapping glass; we’re matching sightlines, preserving interior trim profiles, and bringing the rough opening up to a level where a modern, code-compliant unit will actually seal. That often means custom sizing rather than stock units.
The climate does the rest. Hot, dry summers with temperatures regularly passing 100°F break down old glazing putty and warp wood frames. Cool, wet winters test flashing and weatherstripping that may not have been touched in decades. And Santa Ana winds, when they come through the foothills, expose every weak seal and loose frame. In our experience across Upland, wind-driven air leaks are the number one reason older windows fail a blower-door test. Energy upgrades here aren’t cosmetic; they’re load-bearing decisions about comfort and utility cost.
Our Main Upland Services
Two jobs dominate the calls we get from Upland homeowners: replacing failed or underperforming windows, and installing them in new construction or addition projects. Patio door work runs close behind, especially on ranch homes where sliding glass opens to a back patio.
Window Replacement in Upland
Replacement work in Upland frequently means retrofitting a modern double-pane unit into an opening built for single-pane wood sash. That involves measuring the existing jamb depth, accounting for out-of-square framing common in 1920s bungalows, and often rebuilding the sill that’s rotted from decades of winter rain. Homeowners in the historic districts near downtown sometimes need custom wood windows to satisfy local preservation guidelines, which is a millwork job as much as an installation one. We stock and install eight manufacturer lines so the right product is spec’d for the home, not whatever’s on the truck. Full details on our Window Replacement in Upland page.
Window Installation in Upland
New installation, whether for an addition, a garage conversion, or a new build, starts with a clean rough opening and a written plan for flashing and drainage. Upland’s winter rains and occasional Santa Ana-driven downpours punish sloppy flashing quickly. We install per manufacturer specification, with the price on paper before the first fastener goes in. For homeowners adding a room or re-windowings a whole exterior wall, installation timing matters; we coordinate with the general contractor’s schedule and don’t leave openings exposed overnight. See Window Installation in Upland for scope and specifications.
Patio Door Installation in Upland
Sliding and French patio doors on Upland ranch homes take abuse from direct afternoon sun and gusty conditions along the foothills. When we install a patio door, we’re checking the threshold, the header, and the condition of the subfloor beneath the track. Many 1970s-era homes have settled enough that the original door no longer slides square; shimming and re-leveling is part of the job, not an extra. We work with Therma-Tru, PGT, and other lines to match the door to the exposure. Details, including sizing and lead times, on our Patio Door Installation in Upland page.

Pricing for Window Company in Upland, CA
What follows are the ranges we quote most often in Upland. Your exact price depends on window size, frame condition, access, and the product line you select. The figure below goes on paper before work starts, and it does not move at the door.
| Service | Typical range in Upland |
|---|---|
| Single window replacement (standard size, vinyl) | $700 – $1,200 installed |
| Single window replacement (custom size, wood) | $1,500 – $3,200 installed |
| Full-home window replacement (10 – 15 windows, vinyl) | $9,000 – $18,000 |
| Full-home window replacement (10 – 15 windows, wood or fiberglass) | $18,000 – $35,000+ |
| New-construction window installation (per opening) | $400 – $900 labor |
| Sliding patio door replacement (6 ft, standard) | $2,200 – $4,500 installed |
| French patio door replacement (6 ft, standard) | $3,500 – $6,800 installed |
| Custom patio door (oversized or multi-slide) | $6,000 – $14,000+ |
| Sill and frame repair (rot repair, per window) | $250 – $700 |
What pushes the price higher in Upland is usually the age of the home. Non-standard rough openings, lead paint containment on pre-1978 exteriors, and rotted framing behind the old window all add labor. Custom-milled wood windows in the historic districts run at the top of the range. The quote we give you is a fixed line-item price; if we find rot after opening the wall, we stop and put the additional cost in writing before proceeding.
