ES Windows Construction in Redwood City, CA | Workshop Contractors
We provide independent Home Remodeling in Redwood City with ES Windows construction, replacement, and repair across Redwood City, CA. We install new ES Windows units, replace failed ones, and service existing aluminum and vinyl frames across 94061, 94062, 94064, and 94065. What makes our ES Windows work different here is simple: we know Redwood City runs two building realities inside the same city limits, and windows behave differently in each one.
We are not an ES Windows dealer and we’re not authorized or sponsored by the manufacturer. We’re a licensed general contractor that has installed, retrofitted, and repaired ES Windows aluminum and vinyl product lines across San Mateo County’s seismic retrofits and downtown infill projects. Our loyalty is to the window opening and the homeowner standing in front of it, not to a sales quota. If you’re dealing with fogged glass, a dropped sash, or sliders that leak when the winter wind drives rain sideways, call us at (844) 384-3361 for a free estimate.
Why Redwood City Residents Choose Us for ES Windows Service
Most window contractors in Redwood City learned ES Windows from a product catalog. We learned the line from job sites. We’ve pulled Series 1000 vinyl single-hungs out of 1960s ranch tract homes in the flats, rebuilt sill pans on aluminum horizontal sliders in 1920s bungalows near downtown, and replaced entire west-facing window banks on hillside custom homes in 94062. That hands-on range matters when the fix isn’t obvious.
Noel Figueroa, our owner and General Contractor – Redwood City, grew up around tradesmen who framed houses by hand and taught him the difference between a repair that holds and one that just gets you to the next rain. He built Workshop Contractors around a simple idea: one contract, one schedule, one team responsible for how every material and trade interacts. When we replace an ES Windows unit, the flashing, the sill pan, the stucco cut, and the interior trim are all our scope. Nobody gets to point fingers at another subcontractor. We match OEM-spec parts where available, source equal-quality aftermarket replacements when a profile has been discontinued, and we’ll tell you straight when replacement beats a third repair cycle on the same frame.

Common ES Windows Construction Problems We Solve in Redwood City
- Dropped lower sashes on Series 1000 vinyl single-hungs. We see this constantly in the 1950s-70s ranch tract homes across the Redwood City flats. The sash balance shoe wears out, the lower sash drops, and the window won’t stay up. The fix is matching the actual ES Windows profile with the correct balance assembly. We also check the tilt latches while we’re in there, because they tend to fail around the same time.
- Whistling and leaking aluminum sliders in older downtown bungalows. The original ES Windows horizontal sliders in early-1900s homes around 94061 and 94063 came with galvanized weatherstripping that’s now worn flat. When Redwood City’s winter rain drives sideways, air and water push through the jamb. We replace the weatherstrip with modern bulb-seal profiles and check the sill pan and weep holes at the same time.
- Fogged glass on west-facing hillside units. In 94062, west-facing ES Windows units take the full dry-season solar load. Failed butyl or glazing seals let moisture into the airspace between the panes, and we get called out for fog you can’t wipe off. Reglazing is often possible if the frame is sound; if multiple units on the same elevation have failed seals, replacement usually makes more financial sense.
- Blocked weep holes and water intrusion on sliders at grade. Many Redwood City homes have sliders that open onto patios or walkways without proper drainage corrections in the original scope. When weep holes clog and water pools against the track, it finds its way into the wallboard below. We clear the drainage path, correct the sill slope, and rebuild the pan when necessary.
- Cracked vinyl frames from seismic movement. Redwood City sits in San Mateo County’s soft-story and seismic retrofit zone. Older ES Windows vinyl sashes can crack at the corners when a home shifts. We’ll tell you honestly whether the frame can be repaired or whether the structural movement means you should address the retrofit before putting new glass in.
ES Windows Service in Redwood City: What Local Conditions Mean for Your Equipment
Redwood City runs two construction realities inside the same ZIP codes. Downtown infill projects and ADUs behind existing homes go through the city’s design review and expedited permitting process, with specific standards for window sizing, glazing, and exterior appearance. Hillside lots in 94062, where we offer our Woodside ES Windows service, sit on expansive clay and slope, which means window replacement scope has to account for soil movement, drainage, and a different flashing detail entirely. The same ES Windows unit installed in a downtown ADU and a Farm Hill hillside home needs different permitting, different sill-pan detailing, and different long-term maintenance. Most window companies treat both projects the same. We don’t, because we’ve pulled failed units out of both.
On a hillside ranch off Farm Hill in 94062, our crew replaced a bank of fogged ES Windows aluminum sliders and a worn vinyl single-hung with new impact-rated units. We cut back the stucco to rebuild the sill pan and flashing against the clay-soil drainage the lot was fighting, then re-set the weep holes and rollers so the sliders track clean and the winter wind-driven rain stays outside where it belongs. That’s the difference between window replacement and window replacement that survives a Redwood City winter.
ES Windows Models & Products We Service in Redwood City
We work on the ES Windows product lines most common in Redwood City housing stock: the Series 1000 vinyl single-hung, the Series 2600 vinyl sliding window, the aluminum horizontal slider, and the vinyl casement and awning series. Our parts approach is straightforward: we match the actual profile, whether that’s a sash balance, tilt latch, roller assembly, weatherstrip, or glazing pane. OEM-spec replacements go in where the manufacturer still supplies them. Where a profile has been discontinued, we source equal-quality aftermarket components that match the extrusion and function. We keep the common failure parts for these lines stocked locally for fast Redwood City turnaround, which means fewer return trips.

FAQs – ES Windows Construction in Redwood City
If the frame is sound and the only issue is worn galvanized weatherstripping, repair is the right call. We can replace the weatherstrip with modern bulb-seal profiles and re-set the weep holes to stop the winter wind-driven rain from pushing through. If the frame is bowed, cracked, or the glass is fogged too, replacement is usually the better long-term investment. Call (844) 384-3361 for an assessment.
Yes, in most cases. Window replacement on hillside lots in Redwood City often triggers both building permit review and, depending on the scope, hillside development standards. If the home sits on expansive clay or a downslope lot, the flashing and sill-pan detail has to meet different requirements than a flatland swap. We pull all permits for our window work and handle the inspections. Call (844) 384-3361 and we’ll confirm what your specific property needs.
For hillside homes in 94062 and west-facing elevations that take hard sun and wind, yes. Impact-rated glazing handles Redwood City’s dry-season heat load better and holds up against winter storm conditions. They’re also a strong choice for downtown infill projects where design review favors modern glazing performance. The cost runs $8,000 – $25,000 depending on unit count and retrofit scope. Call (844) 384-3361 for a written quote.
Yes. We match the Series 1000 profile using OEM-spec sash balances, tilt latches, and weatherstrip where ES Windows still supplies them. If the profile has been discontinued, we source equal-quality aftermarket components that fit the extrusion without modification. We’ll match the frame color and glass package as closely as the current market allows.
We prepare the window submittals to meet the city’s downtown precise plan standards, including glazing, mullion layout, and exterior finishes, then manage the review comments alongside the rest of the construction scope. Because we’re the general contractor on the project, the windows, flashing, siding, and interior trim all stay under one contract and one schedule. Call (844) 384-3361 to talk through your project.
