ES Windows Construction in San Bruno, CA | Spruce Contractors
We provide independent ES Windows service across San Bruno, from window replacement and impact window installation to roof repair on homes where these older units were originally installed. The thing that makes our work here different: we understand how San Bruno’s fault-zone designation and marine-fog climate interact with ES Windows frames, flashing, and openings. Call (877) 265-5771 for a free estimate.
Why San Bruno Residents Choose Us for ES Windows Service
Most San Bruno homes were built between the 1940s and 1960s, which means the ES Windows units we see are either original aluminum single-pane or early dual-pane from that era, or Series 200/300 vinyl replacements installed later. We know both generations well. Nate Calloway, our owner, grew up in Hillsborough and trained at College of San Mateo before spending years on job sites across San Mateo County. He’s pulled enough fogged sashes and seized rollers in this ZIP code to tell you within a few minutes whether a unit is worth re-glazing or should go.
We’re an independent contractor, not an authorized ES Windows dealer, and that’s the point. We sell honest repair-versus-replace judgment, not a brand badge. If the frame is sound and the only issue is a failed seal or worn hardware, we source OEM ES Windows parts where available and quality aftermarket hardware when the OEM line is discontinued. If the rough opening has rot and the flange failed years ago, we’ll tell you that too.

Common ES Windows Construction Problems We Solve in San Bruno
- Fogged dual-pane glass from failed seals. San Bruno’s persistent summer fog and cool-night/warm-day cycling stress the sealant on older ES dual-pane units. We see this constantly on 1960s-era aluminum sliders and 1980s-vintage vinyl replacements. When the frame is still straight, we re-glaze with matching OEM glass and restore the unit for a fraction of replacement cost.
- Aluminum frame pitting and oxidized weatherstripping. Salt-laden marine fog eats at exposed aluminum on older ES single-pane units and sliding patio doors. The frames pit, the weatherstripping hardens and cracks, and drafts start finding their way in. We replace the stripping and address the corrosion properly before it spreads.
- Water intrusion where flanged ES windows meet stucco. This is the big one in San Bruno. Original 1940s-1960s wood framing was rarely flashed to modern standards, and stucco-clad tract homes trap moisture at the rough opening. We regularly cut away rot at the sill, re-flash with proper flashing tape, and re-set the unit so water can’t wick into the cripple wall below.
- Sliding panels that seize after winter rains. When the original wood frame swells from San Bruno’s winter moisture, the ES slider track binds and the rollers grind. On a raised-foundation ranch, that moisture often travels down from a failed roof edge, which is why we check the roofline and roof repair needs at the same time.
- Out-of-square openings from foundation settling. Hillside lots and raised foundations settle over decades, and an ES window set square in 1962 may be racked half an inch out of plumb today. We re-shim, re-flash, and sometimes reframe the opening so the sashes actually close and lock.
ES Windows Service in San Bruno: What Local Conditions Mean for Your Equipment
San Bruno sits directly on the San Andreas Fault zone, and the defining construction reality here is seismic retrofit: foundation bolting, cripple-wall bracing, shear-wall upgrades. Here’s the part people don’t think about: window and door work on older San Bruno homes sometimes has to coexist with a retrofit, because the original ES units were set into cripple walls that are only 18 to 24 inches tall and packed with original diagonal wood sheathing. When we open a rough opening to replace or re-flash an ES window, inspectors on the Peninsula want to see what’s behind it. We’ve had jobs where pulling a rotted ES slider turned into re-flashing, reframing, and coordinating with the retrofit crew so both scopes pass inspection together. Our crew has handled this sequencing on raised-foundation ranches off Crestmoor and throughout 94066. Millbrae homeowners don’t face this the same way. Good work doesn’t need a lot of explaining – you can see it.
ES Windows Models & Products We Service in San Bruno
We service the full spread of ES Windows units common to San Bruno’s housing stock.

FAQs – ES Windows Construction in San Bruno
My ES Windows double-pane units are fogging between the glass – is that the window or the San Bruno fog?
It’s a failed glass seal, not the outdoor fog. The persistent moisture and temperature swings in San Bruno accelerate seal degradation, but the fog is trapped inside the unit. We can re-glaze the sash with OEM glass when the frame is straight, or replace the unit if the frame is also compromised. Call (877) 265-5771 for an exact quote, and estimates are free.
Can you replace just the glass in my older ES aluminum slider instead of the whole window?
Yes, in most cases. If the aluminum frame is square and the track isn’t corroded through, we replace the insulated glass unit and weatherstripping while the frame stays put. You save significantly over full replacement. If the frame has heavy pitting or the rough opening is rotted, replacement becomes the better call.
Will window work on my San Bruno home need to account for the fault-zone retrofit?
It often does. On pre-1960s raised-foundation homes with cripple walls, inspectors want to see the connection between the window opening and the shear wall. We coordinate window replacement with retrofit work so both scopes pass together. If you’re doing one, we’ll tell you honestly whether the other should be sequenced in.
Why do my ES windows leak at the corners after winter rain?
Most likely the original flange or builder’s flashing has failed where the window meets the stucco and 1940s – 1960s wood framing. Water wicks into the opening, then into the cripple wall below. We fix it by cutting away rotted framing, re-flashing to current standards, and re-setting the unit plumb.
Are you authorized by ES Windows, and does that affect warranty?
No, we’re an independent contractor and not authorized, sponsored, or endorsed by ES Windows. If your ES Windows units are still under an ES Windows manufacturer warranty, that warranty sits with the brand. What we offer is independent judgment on repair versus replace, and our own workmanship warranty covers what we install. Call (877) 265-5771 to walk through your situation.
