ES Windows Construction in San Jose, CA | Workshop Contractors
We install and service ES Windows vinyl and aluminum units across San Jose, and we do it as an independent contractor, not an authorized dealer. That independence matters because it lets us give you a straight answer on repair versus replacement, including when an aftermarket part beats waiting on a discontinued OEM sash. If your San Jose home needs ES Windows work, call (844) 384-3361 for a free estimate. We know the older housing stock here, we know the infill rules, and we know how these frames behave when they’re set into a 1920s opening that hasn’t been square since the Truman administration.
Why San Jose Residents Choose Us for ES Windows Service
Most window contractors in San Jose know vinyl replacement windows in general. Fewer know the specific quirks of ES Windows profile designs, which model years used which glazing beads, and when a fogged dual-pane unit is worth replacing versus when the whole sash has warped past saving. We have been working with ES Windows units on ES Windows sales & service across the valley long enough to know the difference by feel. Noel Figueroa, our owner and general contractor, grew up around tradesmen who taught him that a window is only as good as the opening it sits in. That lesson drives how we bid every job in San Jose, especially in the older core where nothing is plumb and nothing is level. We source OEM ES Windows sashes, glazing, and hardware where the profile is still supported, and we keep measured aftermarket IGU and weatherseal inventory ready for the units where OEM has gone discontinued or slow. We’re a single-source general contractor, which means the same crew that reframes your rough opening also sets the window and seals the sill. No finger-pointing between a window guy and a framing guy.

Common ES Windows Construction Problems We Solve in San Jose
Here is what we actually see on ES Windows units throughout San Jose service area homes:
- Warped or bowed vinyl sashes on west- and south-facing units. San Jose’s dry, high-summer-heat afternoons bake these frames year after year. Once the vinyl bows, the edge seals fail and the window starts leaking air, which means wildfire smoke from the valley’s summer fires finds its way inside. We replace the sash when the profile is still supported, or tell you honestly when the whole frame needs to go.
- Binding and misaligned locks on pre-1940s bungalows. In downtown-core neighborhoods like 95112, the original rough openings have sagged with the raised foundation. A new ES Windows unit set into that out-of-square hole will bind, the lock will not catch, and the sill will leak. We reframe and shim the opening first, then set the window so it actually operates.
- Fogged dual-pane insulated glass from failed perimeter seals. Fifteen to twenty-five year old valley stock goes through thousands of thermal cycles between hot afternoons and cool nights. When the seal goes, you get condensation between the panes that will not wipe off. We replace the IGU with a measured quality aftermarket unit when OEM is discontinued.
- Failed weatherstripping and worn sweep seals at the sill. This shows up as a draft you feel on cold mornings and water staining at the sill after the first real rain. On homes where a prior unpermitted addition left the opening out of level, the seal wears unevenly and fails fast.
- ES Windows sliding patio doors that have settled out of track. San Jose’s expansive clay soils move with moisture, and over time a sliding door that once rolled smoothly starts grinding. We reset the track, replace worn rollers and sweep seals, and get the door sliding again or swap the panel if the frame is torqued.
ES Windows Service in San Jose: What Local Conditions Mean for Your Equipment
Here is the thing most window companies will not tell you about San Jose: the valley floor is essentially built out. With little raw land left, most new window work lands on infill projects, ADUs, SB 9 lot splits, and tear-down rebuilds. That means new ES Windows units have to clear City of San Jose planning review and Title 24 glazing requirements that surrounding cities apply very differently. On an SB 9 lot-split rebuild off a downtown-core street in 95112, we replaced the failing ES Windows double-hung units in a 1920s bungalow where the raised-foundation rough openings were badly out of square. We reframed and shimmed each opening, reset ES Windows vinyl double-hung units and a sliding patio door, and sealed the sills so the new second unit and the original house both passed Title 24 glazing. The owner got draft-free, smoke-tight units without tearing into the unpermitted garage conversion at the rear. That job is not unique in San Jose. It is the norm in the older core, where bungalows and craftsman homes built between 1900 and 1940 hide out-of-square framing, knob-and-tube wiring, and prior additions that were never permitted. Every ES Windows unit we set has to be tied into that reality, not just dropped into a hole and caulked.
ES Windows Models & Products We Service in San Jose
We work on the full ES Windows range that shows up in San Jose homes and multifamily projects. That includes vinyl single-hung and double-hung replacement windows, vinyl sliding patio doors, aluminum series windows for multifamily and ADU projects, and fixed and awning units in vinyl frames. Our parts approach is simple: we source OEM ES Windows sashes, glazing, and hardware where the profile is still supported and the lead time is reasonable. When OEM is discontinued or backordered for months, we use measured quality aftermarket IGU and weatherseal replacements that match the unit’s sightlines and thermal performance. We will also tell you straight when a warped or rotten frame means full replacement beats patching a single pane. Build it right the first time. The second time costs twice as much and nobody’s happy about it.

FAQs – ES Windows Construction in San Jose
Yes, when specified with the correct glazing package and installed to code. San Jose requires ADUs to meet current Title 24 energy standards, which include specific U-factor and SHGC ratings for glazing. We verify the unit specs against the project’s energy calculations before ordering anything, so you do not fail final inspection. Call (844) 384-3361 and we will walk you through the requirements for your specific lot.
In many cases, yes, but it depends on how far the original rough opening has sagged. We reframe and shim only where the opening is out of square enough to cause binding or leaking. Some openings just need new flashing and a properly sealed sill. The only way to know is to pull the trim and check, which we do during the free estimate visit.
The sticking is from vinyl expansion in San Jose’s dry summer heat, usually on west- and south-facing units. The fogging is a failed perimeter seal in the dual-pane IGU, common after 15 to 25 years of thermal cycling. We can replace the IGU and often correct the binding without replacing the entire window, unless the sash itself has warped. Call (844) 384-3361 for a quick diagnosis.
In older San Jose neighborhoods, it can. The City may require you to legalize or demolish existing unpermitted work before approving new scope, especially if the window work touches the unpermitted area. We have navigated this in 95112 and the surrounding older core, and we can tell you what to expect before you spend a dollar on materials.
Yes. We install and service ES Windows aluminum series units on multifamily and ADU projects, and we have worked SB 9 lot splits where both the original house and the new second unit needed Title 24 compliant glazing. One contract, one schedule, one crew responsible for the whole envelope. Call (844) 384-3361 to talk through your project.
