We’re Ashford Contractors, and we service, repair, and install ES Windows throughout South San Francisco, CA, with ES Windows repair in Daly City also available nearby.

What makes our ES Windows work different here is that we check the wall, the flashing, and the rough opening before we ever blame the window. If you’re dealing with fogged glass, a sticky slider, or water showing up where it shouldn’t, call us at (877) 752-3868 for a straight answer and a free estimate.
Why South San Francisco Residents Choose Us for ES Windows Service
Most window companies in South San Francisco sell you a replacement. We start by figuring out whether you actually need one. Our owner, Glen Mossier, grew up on the Peninsula, trained at Skyline College in San Bruno, and spent two decades learning what fog, wind-driven rain, and salty air do to vinyl window lines, ES Windows included. That background matters on the flatlands and up the hill, where the same window performs very differently depending on which side of 101 you’re on.
We work with ES Windows vinyl single-hung replacements, horizontal sliders, casement and awning units, and patio sliding glass doors. We know which balances wear out first, where the weep paths clog, and what a fogged double-pane unit actually costs to reglaze versus replace. And because we’re local to the Peninsula, we can get eyes on your windows in South San Francisco without a two-week scheduling runaround.

Common ES Windows Construction Problems We Solve in South San Francisco
Here’s what we see repeatedly on ES Windows in South San Francisco housing stock, and what’s usually driving it:
- Bowed or sticking vinyl sashes. West-facing openings in the flatlands catch direct afternoon sun. Vinyl expands and bows, then the damp winter air off the San Bruno Gap swells the frames tighter. We assess whether the frame is salvageable or whether the weld has started to crack.
- Fogged insulating glass units. Older ES vinyl windows, especially in Sunshine Gardens mid-century tract homes, start losing their seal after 15 to 25 years. Condensation between the panes is a sealed-unit failure, not a house humidity problem. We source OEM sashes where the frame profile is still viable.
- Water intrusion at sill pans and old flashing. The early-1900s worker cottages and bungalows in Old Town and the blocks west of 101 often have thin or missing flashing behind the original window frames. Fog-belt condensation sits at the sill, the weep path clogs, and water finds its way in. The window gets blamed. Usually it’s the rough opening.
- Slider and patio door hardware fatigue. Grit, coastal damp, and years of use destroy rollers, tracks, and balances on ES sliding windows and patio doors. We replace what’s worn, match the OEM profile, and make sure the drain path still works.
- Wind-driven rain and weep-hole debris. South San Francisco gets real storms off the gap. Fine debris packs into the bottom track, the weep holes plug, and water ponds inside the frame. Sometimes the fix is a good cleaning and a slight pitch correction. Sometimes it’s more.
ES Windows Service in South San Francisco: What Local Conditions Mean for Your Equipment
Here’s a fact about South San Francisco that most window contractors never mention: this is the Industrial City, and a large number of lots, especially along the flatlands near the old cement and steel corridor, sit on undocumented industrial fill. Before we set or replace an ES window, we confirm that the wall and header are what they appear to be. Old plant-land construction rarely matches the drawings. A header that looks solid can be a notch-cut, under-sistered mess hiding behind drywall. If we skip that step, we’re installing a good window into a bad opening, and when the window leaks, sags, or binds a year later, everyone blames the glass.
That’s the difference between a window salesman and a general contractor. We’re the latter. We check the wall cavity, the flashing, and the rough opening before we touch the window. And on older worker cottages near the old industrial corridor, we’ve pulled enough buried foundations and undocumented fill surprises to know that utility locating and soils screening are never a formality on South City jobs.
ES Windows Models & Products We Service in South San Francisco
Our team covers the full ES Windows vinyl lineup: single-hung replacement windows, horizontal sliding windows, casement and awning windows, and vinyl patio sliding glass doors. When a frame is sound, we source OEM ES Windows sashes, balances, rollers, and glazing units. When OEM is discontinued or the lead time is months out, we use quality aftermarket hardware that matches the profile and drainage pattern so the window still sheds water properly. We keep common ES-compatible hardware in local stock, which means most South San Francisco repairs don’t wait on a freight truck from the Southeast.
If the vinyl frame is bowed, cracked at a weld, or the rough opening was never flashed correctly, we’ll tell you replacement is the right call, not a patch job. That’s the honest answer, and it’s the one we give even when a smaller repair would have been easier to sell.

FAQs – ES Windows Construction in South San Francisco
Fog between the panes is a failed insulating glass seal, which is common on older ES vinyl units in South San Francisco’s fog-belt climate. Water on the interior side of the glass is condensation, usually driven by poor airflow, cold glass, and damp winter air off the Broadmoor and San Bruno Gap. Both issues have different fixes: sealed-unit replacement for the first, and often drainage or ventilation work for the second. Call (877) 752-3868 and we’ll diagnose it properly.
Yes, when the frame is square, structurally sound, and still draining, we replace just the sashes with OEM ES Windows parts or a profile-matched aftermarket alternative. If the frame is bowed, cracked at a weld, or the rough opening was never flashed, we’ll recommend full replacement because a sash swap won’t fix the underlying problem. The estimate is free either way.
On South San Francisco flatlands, it’s usually the house. Sun exposure on a west-facing wall expands the vinyl frame and the header above it settles. We check the opening for square before we touch the roller or track. If the header is undersized or the fill beneath the slab has shifted, new rollers will only mask the problem for a season. We fix the structural issue and the door.
They can. South San Francisco reviews window work that changes structural openings or sits on older lots with undocumented fill and buried foundations more carefully than other Peninsula cities. We handle the permit paperwork, the inspections, and any required documentation as part of the project. Whether your job needs a permit or not, we’ll tell you up front, not after the inspector shows up.
No, and we’ll say that before you spend money on windows. A leak at the roof-wall junction is a flashing, roofing, or wall-drainage problem. New windows won’t stop water that’s entering above the window plane. We inspect the junction, the eave, and the wall flashing, often as part of the same visit. Our roof repair work runs $470 – $2,125, and we’ll show you exactly where the water is entering.
