ES Windows Construction in San Antonio Heights, CA | San Mateo Construction
We provide independent ES Windows construction service across San Antonio Heights, from fogged glass replacement to full window reframing on hillside homes. What makes our ES Windows work different here is simple: we’re the contractor who already knows San Bernardino County’s unincorporated permitting process and how Chapter 7A wildfire code shapes every glazing decision. We’re not authorized by or affiliated with ES Windows. We’re just the team that has spent years servicing their products in the foothills above Upland ES Windows service areas. Call (855) 901-7266 for a free estimate.
Why San Antonio Heights Residents Choose Us for ES Windows Service
ES Windows vinyl single-hung and slider series show up on a lot of the 1950s through 1970s ranch and split-level homes here, and by now most of those units are 15 to 20 years in service. That’s exactly the age where seals fail, sashes bind, and weatherstripping turns brittle. We know which ES Windows profiles were used in San Antonio Heights homes of this era, because we have pulled enough of them out of rough openings on sloping lots to recognize the framing patterns. Noel Carrington grew up learning this trade from his father pouring concrete footings on the Peninsula, and he approaches every window job the same way he approaches a framing package: measure twice, order the right profile, and don’t hide a problem behind trim. We carry OEM-compatible balances, glazing, and hardware wherever ES Windows still supports the line, and we keep a local stock of aftermarket weatherseal for the older profiles that are no longer made. When you call us about a binding slider on the west side of your house in San Antonio Heights, we know what that heat distortion looks like before we arrive.

Common ES Windows Construction Problems We Solve in San Antonio Heights
- Vinyl frame distortion on west and south elevations. San Antonio Heights sits at the base of the San Gabriels, and the summer sun here pushes surface temperatures on exposed window frames past what early vinyl extrusions were rated to handle. We regularly see sashes that have bowed enough to bind in the track, especially on older ES Windows single-hung units facing south across the canyon.
- Fogged insulating glass units. Failed seals let moisture between the panes, and we see this constantly on ES Windows now 15-plus years in service across San Antonio Heights. If the frame is sound, we reglaze with dimensionally matched glass. If the frame has gone with it, replacement is the honest call.
- Weatherstripping and sweep deterioration from Santa Ana grit. Seasonal Santa Ana winds carry fine dust and grit that chews through window sweeps and weatherstripping. Homeowners notice the draft first, then the whistle. On sliders and single-hung interfaces, this is usually the fix that returns the window to quiet operation.
- Water intrusion at sill pans on hillside rough openings. Many original ES Windows installations in San Antonio Heights were detailed for a flat-lot condition, not a stepped or cantilevered wall. When the sill flashing fails on a hillside home, water gets into the wall behind the siding. We re-detail the flashing for the actual slope, not the assumption it was built on.
- Patio door systems with worn rollers and dropped panels. ES Windows sliding glass doors on older San Antonio Heights homes often sit on worn rollers, which lets the panel drop and drag across the track. It’s a straightforward rebuild, but it takes the right hardware, and we keep common OEM and matched aftermarket parts on hand for faster turnaround.
ES Windows Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
Here’s what changes everything for ES Windows owners specifically in San Antonio Heights: this unincorporated foothill community pulls its construction permits through San Bernardino County, not the City of Upland. If you’re replacing windows on a hillside home here, the county can require geotechnical review on grading plans before window and glazing work moves forward. That’s something a flatland Upland or Rancho Cucamonga ES Windows service job never has to contend with. Our window scope gets sequenced around county inspection timing because if the windows go in before the site work is signed off, the project stops dead. We saw this on a split-level ranch off Ridgeview Drive, where our client needed a set of fogged ES Windows vinyl sliders replaced on the wind-exposed west elevation. Two rough openings had to be reframed, the original sill flashing had failed and was letting water into the wall, and the county required the hillside drainage detail before they would release the frame inspection. We matched the OEM vinyl profile where it was still available, upgraded the glazing on the view-facing panes, and re-detailed the flashing to the stepped wall. The work passed county inspection and the winter draft disappeared. That’s the difference between a window contractor who has done this in San Antonio Heights and one who is learning the county process on your project.
ES Windows Models & Products We Service in San Antonio Heights
We service the full range of ES Windows product lines found on San Antonio Heights homes. That includes vinyl single-hung and slider window series from the 1980s through current production, the aluminum series used widely in 1960s and 1970s replacement work, and picture and awning window combinations that face the foothill views on the north slopes. We also handle ES Windows sliding glass doors and patio door systems, including roller rebuilds, lock replacement, and full frame swaps. Our parts approach is straightforward: where ES Windows still supports the profile, we order genuine OEM sash, balances, glazing, and hardware. Where a model line is discontinued, we spec dimensionally matched aftermarket glass and weatherseal from suppliers whose tolerances we have verified on our own jobs. For window replacement and impact window installation, we help you select the right package for your exposure, and we anchor every recommendation to the actual conditions at your address in San Antonio Heights.

AfterES Windows Service Pricing in San Antonio Heights
Window work in San Antonio Heights costs what it costs for reasons you can see from the curb: steep lots, county inspections, Chapter 7A glazing requirements, and existing framing that occasionally needs more than a sash swap. Here are the ranges we quote for ES Windows work on these hillside homes:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
What drives the spread is scope: a straight sash replacement on a supported ES Windows profile lands at the bottom of the range, while full frame replacement with reframing, upgraded glazing, and hillside flashing detail climbs toward the top. Frameless glass shower enclosures, which we also handle, run separately and depend on panel size and hardware choices. Your free estimate includes a site walk, a look at the existing rough openings, and a written line-item quote before we ever order material. Call (855) 901-7266 to schedule one.

FAQs – ES Windows Construction in San Antonio Heights
Yes, in most cases. Window replacement in unincorporated San Antonio Heights is permitted through San Bernardino County, not the City of Upland, unlike ES Windows repair in Montclair, and hillside homes can trigger additional geotechnical review before the window scope gets approved. We handle the permit package and sequence the work around county inspection timing so your project doesn’t stall. Call (855) 901-7266 and we’ll tell you exactly what your address requires.
Fogging means the insulating glass unit’s seal has failed and moisture is now trapped between the panes. On older ES Windows units in San Antonio Heights, this typically shows up after 15 or more years of service, and heat cycling on sun-facing elevations accelerates the failure. If the frame is still sound, we reglaze the sash with matched glass; if the frame has distorted, replacement is the better investment. Call (855) 901-7266 for an assessment and a written line-item quote.
Current-production ES Windows vinyl is rated to handle the heat levels we see here, but early-generation vinyl extrusions on west- and south-facing elevations can distort over time, especially where the unit gets direct foothill sun all afternoon. If the frame is still square, weatherseal replacement and hardware rebuilds can restore function. If the sash has bowed or the frame has twisted, we’ll tell you straight and recommend replacement. Call (855) 901-7266 to schedule a site check.
It does. San Antonio Heights sits within a high fire severity zone, and San Bernardino County enforces Chapter 7A wildfire construction standards for building materials, including windows and glazing on new and replacement work. That means tempered glass requirements, ember-resistant frame detailing, and specific installation methods that a flatland job never deals with. Our window scope accounts for every one of those code provisions before we order material. Call (855) 901-7266 to get an exact quote for your project.
Absolutely. San Mateo Construction is a General Contractor in San Antonio Heights, so the same team handling your ES Windows replacement here can also install a frameless glass shower enclosure in the same project, under one contract and one permit package where applicable. We bring in Kohler or Grohe plumbing fixtures and Schluter waterproofing where wet-area work is involved, so you’re not juggling three separate trades. Call (855) 901-7266 to scope both at once and we’ll give you a single line-item quote. Tell me what you actually need, and we’ll figure out the right way to build it.
