ES Windows Construction in Ontario, CA | Hampton Contractors
We provide independent ES Windows construction and repair service across Ontario, from the 1950s-era stucco tracts in the 91761 and 91762 core up through the 1990s and 2000s subdivisions in 91764, and we also serve ES Windows in Rancho Cucamonga. What makes our ES Windows work different here: we know these units age through Ontario’s rough combination of 100-degree inland summers, Santa Ana wind grit, and slab-on-grade foundation movement in the older neighborhoods. That local context changes how we diagnose a sticky slider or a fogged fixed window, and it is the reason most of our repair calls do not end in a full replacement quote. Call (833) 467-4075 to have us look at your ES Windows units, and we will tell you straight whether they need re-tracking, re-glazing, or replacement.
Why Ontario Residents Choose Us for ES Windows Service
Hampton Contractors has installed and serviced ES Windows sliding-glass patio doors, single-hung and slider windows, fixed picture units, and awning windows across Ontario and ES Windows in Upland long enough to know which failure modes show up in which neighborhoods. The older core near Euclid Avenue and Holt Boulevard runs on post-WWII slab foundations that move seasonally, so we see ES frames that were plumb at install now sitting out of square. The newer subdivisions see less foundation movement but more direct sun gain on west-facing ES fixed windows, which drives fogged insulated glass. As an independent contractor, we diagnose and repair ES Windows products on their actual merits. We are not authorized by, partnered with, or a warranty agent for ES Windows. That independence matters because it means our repair recommendations are based on what the unit actually needs, not what a manufacturer program pays us to push. Brent Calloway, our owner, grew up in the High Desert and learned framing, finish carpentry, and building-science fundamentals at Victor Valley College, and he runs our ES Windows service calls with the same straight-talk approach he has used on Hesperia job sites for over two decades.

Common ES Windows Construction Problems We Solve in Ontario
These are the ES Windows issues we see repeatedly across Ontario, and most of them trace back to this city’s specific housing stock and weather patterns.
- Vinyl sash distortion and roller-track binding on sliding glass doors. In Ontario’s 100-degree-plus summers, a west-facing ES slider in an unshaded opening absorbs direct sun all afternoon. The vinyl frame and sash expand at different rates than the glass and track, and after enough seasons the rollers bind and the door grinds. This is typically a repair problem, not a replacement problem, unless the frame itself has warped beyond shimming.
- Fogged insulated glass units on fixed and slider windows. The long west and south exposures common in Ontario’s 1950s-70s tracts mean ES fixed windows take brutal thermal cycling. When the perimeter glazing seal fails, moisture creeps in and the IGU fogs permanently. We swap only the failed glass unit when the frame is sound, which saves the homeowner the cost of a full window replacement.
- Pack-out of slider tracks and weep holes during Santa Ana events. Ontario sits in the Santa Ana wind corridor, and those wind events push fine dust and grit into ES slider tracks and weep holes. The track fills, the weep holes clog, and the door either drags or holds water. This one is simple to fix when it is caught early, but it will ruin rollers if ignored for a season or two.
- Perimeter sealant and caulking failure around window and door openings. Ontario’s shrink-swell clay under the older slab-on-grade core creates hairline movement in stucco and in the rough openings around ES window and door frames. That movement works caulking and flashing loose over time, and then the opening leaks during winter rain or wind-driven storms. We re-flash and re-caulk as part of any ES window or door service call where the opening shows movement.
- Out-of-square rough openings from slab movement. This is the signature Ontario core-neighborhood failure. When the slab shifts, the rough opening around an ES window or patio door shifts with it, and the frame binds even if the rollers and track are fine. Brent’s construction background means we re-shim and re-set frames rather than just slapping new hardware into a moved opening and hoping it holds.
ES Windows Service in Ontario: What Local Conditions Mean for Your Equipment
There is one Ontario-specific fact that shapes ES Windows construction work here more than anything else, and it is the shrink-swell clay under the older neighborhoods. In the 91761, 91762, and 91764 core, these 1950s-to-1970s single-story stucco tract homes sit on slab-on-grade foundations that ride on clay that expands when wet and shrinks when dry. Ontario’s hot, dry summers pull moisture out of that clay, and the slab moves. The rough openings around ES window and patio door frames move with it. On a 1962 single-story stucco tract home in the 91762 core, our crew pulled a pair of ES sliding-glass patio doors whose rollers had flat-spotted and whose tracks were packed with wind-blown grit, and we found the header out of square from slab movement that had cracked the stucco around the opening. We re-shimmed the frame, replaced the rollers and track with spec-matched hardware, re-flashed and re-caulked the opening, and the sliders ran smooth through the next Santa Ana wind advisory. On the separate ES fixed windows we found fogged IGUs and swapped only the failed glazing units rather than the whole frames. That single job, which is typical of what we see in Ontario’s older core, explains why our re-tracking and re-shimming work here is driven by foundation movement as often as by worn rollers. If you own an ES unit in the older core and it has started binding or sticking, do not assume the hardware is the problem until someone has checked the opening itself.
ES Windows Models & Products We Service in Ontario
Our crew works on the full ES Windows product range that shows up in Ontario homes: vinyl single-hung and slider windows, horizontal rolling window series, fixed and awning units, and sliding glass patio doors. We use OEM ES Windows rollers, sash hardware, and glazing where that hardware is available, and when an OEM part is discontinued or backordered we install spec-matched aftermarket equivalents. We will not invent part numbers or promise a factory part we cannot get, but we will tell you exactly what is going in and why it is the right fit. For fast turnaround across Ontario we keep common ES roller sizes, track stock, and glazing seal materials on the truck, so most repair calls do not wait on a parts shipment. When a full replacement is the honest answer, we install new ES Windows units and we also handle the broader ES Windows sales & service scope, including impact-rated window packages where the project calls for them.

AfterES Windows Service Pricing in Ontario
Ontario homeowners usually want a straight number before they commit to a service call, so here is the pricing reality for ES Windows construction work in this market. What drives the cost on any given job is whether we are repairing hardware and glazing or replacing full units, and on replacement work the opening condition matters as much as the window itself. In the older slab-on-grade core where openings have moved, re-shimming and re-flashing adds labor that a clean new-construction opening would not require. A free estimate from us includes the inspection, the diagnosis, and a line-item written quote before any work starts.
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
These are the ranges we quote across Ontario, and the final number depends on window count, opening size, frame condition, and whether the job includes re-flashing or stucco repair around the openings. Call (833) 467-4075 and we will give you an exact number for your house, not a ballpark that moves later.

FAQs – ES Windows Construction in Ontario
It is usually both, and in Ontario’s older slab-on-grade neighborhoods the frame is often the hidden culprit. Heat softens and distorts the vinyl enough to bind, but when the rough opening has moved from clay shrink-swell, the frame itself is out of square, and new rollers alone will not fix the grind. We check the header and sill for square before we order parts, because re-shimming a moved frame is half the repair in the 91761 and 91762 core. Call (833) 467-4075 and we will diagnose it on site.
Fixed and picture windows take more static thermal stress than operable units, especially on long west and south exposures in Ontario. The framing around a fixed ES unit expands and contracts against the glass edge seal all summer, and once that seal fails the insulated glass unit fogs. Sliders have more frame flex and movement, which actually relieves some of that edge stress, so they often fog later or not at all. When only the IGU is failed and the frame is sound, we replace the glass unit alone rather than the whole window.
ES Windows does not carry the impact-rated line that PGT or CGI are known for, and Ontario is not in the hurricane wind zone, so code does not require impact glazing here. What Ontario homes do deal with is Santa Ana wind-driven debris, and while most ES units hold up to that wind load when properly flashed and sealed, the real durability problem is dust and grit packing the tracks and weep holes over time. If you want heavier wind protection or are doing a kitchen remodel with new openings, ask us about ES Windows service in Calimesa patterns, where wind exposure is comparable, or call (833) 467-4075 to talk through glazing options for your specific exposure.
Yes, and it should be planned from the start, not added after the cabinets are set. A full kitchen remodel in Ontario runs $14,000 to $45,000, and adding new ES windows or replacing old ones during the job is the most cost-efficient time to do it, because the openings are already open and the stucco and flashing work can happen once, just as we do for ES Windows in San Antonio Heights. Waiting until after the cabinets and counters are in adds labor and risk to the window install. Call (833) 467-4075 and we will fold the ES window scope into your kitchen estimate as one line item, not a separate surprise.
Not necessarily. In Ontario’s older core, hairline stucco cracks around window and door openings are usually the slab moving, not the window failing. The ES frame may still be perfectly square and serviceable even when the surrounding stucco shows a seasonally cycling crack. That said, the crack is a warning sign that the opening has moved, and the window or door needs checking for racking and sealant failure while the movement is still small. We would rather inspect it now than replace a bound frame later.
