ES Windows Construction in Los Altos, CA | Seaside Contractors
We provide independent ES Windows construction, replacement, and repair service across Los Altos, including ZIP codes 94022, 94023, and 94024. What makes our ES Windows work different here is that every job gets planned around the city’s tree-protection rules, so your replacement doesn’t stall out at the permit counter. We’ve serviced these window systems in enough Los Altos homes to know that a heritage oak near the foundation shapes the whole project. Call (833) 589-8103 for a free estimate on any ES Windows work.
Why Los Altos Residents Choose Us for ES Windows Service
ES Windows builds a genuinely good product, and most of what we see in Los Altos are systems that have served a home for fifteen or twenty years and are starting to show their age. Fogged glass, tired hardware, sagging sashes. Glen Sorrento, our owner, studied building construction technology at College of San Mateo and has spent the decades since working through nearly every project type the Peninsula throws at a contractor. That matters when you’re deciding between rebuilding an existing ES Windows frame and pulling the whole unit. We’re an independent specialist, not a manufacturer shop, so our only interest is telling you which route actually makes sense for your home and budget. When we recommend ES Windows sales & service work, it’s because the frame and glass justify it, not because a quota needs hitting.

Common ES Windows Construction Problems We Solve in Los Altos
- Fogged insulated glass units (IGUs) with failed argon fill. We see this constantly in Los Altos on original ES Windows 4000 and 6000 Series units from the 1990s and early 2000s. The seals degrade, argon leaks out, and the glass clouds over. Replacement IGUs restore clarity and thermal performance without replacing the frame.
- Sill leakage during winter rain events. The November through April rain season in Los Altos puts real stress on aging window flashings. We’ve repaired dozens of ES Windows sills where the original sealant had cracked and water was working into the wall cavity on the windward side of ranch homes.
- Hardware fatigue on casement and awning operators. Twenty years of hand cranks adds up. We replace tired crank mechanisms, hinges, and locking points on ES Windows casement and awning units so the sashes close tight again.
- Sliding door roller and track wear on ES Windows patio doors. Los Altos backyards mean patio doors get daily use. Worn rollers make doors drag, then bind. We rebuild the track hardware and realign the panel, which usually avoids a full door replacement.
- Root-related settlement putting window openings out of square. This is the one that’s uniquely Los Altos. Mature coast live oaks pull moisture from the soil, and the expansive-clay shrink during dry summers can shift shallow foundations. When an ES Windows frame is racked even an eighth of an inch out of square, sashes bind and locks stop aligning. We reset and shim before considering replacement.
ES Windows Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos is not like most Silicon Valley suburbs, and it matters for window work in a very specific way. The city’s tree-protection ordinance for heritage coast live oaks routinely requires root-zone fencing and can limit excavation near foundations. On a ranch-style home in the Old Los Altos neighborhood, we replaced a set of fogged ES Windows 6000 Series fixed and casement units that had lost their argon fill and were leaking at the sill during heavy rains. Our crew carefully worked around a protected oak’s drip line, using manual tools and a smaller lift to avoid root damage, and installed new IGUs with upgraded low-E glass and fresh flashing. The homeowner noted immediate improvement in clarity and a drop in street noise. That’s the reality of window construction in Los Altos: you design the staging plan around the tree before you touch the window. A contractor who doesn’t know the ordinance is going to get red-tagged, and your project pays for it in delay. We flag heritage oaks during the estimate visit, not after the permit gets filed.
ES Windows Models & Products We Service in Los Altos
We work on all four major ES Windows residential lines: the 3000 Series, 4000 Series, 6000 Series, and 8000 Series. That covers a good portion of the window inventory in Los Altos, since so many of the 1950s and 1960s ranch homes here were renovated with mid-tier and premium aluminum-framed systems during the 1990s and 2000s boom. Our parts approach is straightforward. We source OEM ES Windows replacement parts when they’re available because exact fit beats close enough, especially on multi-point locks and hinge hardware. When a part’s been discontinued or the lead time is weeks, we’ll use a high-quality aftermarket equivalent and tell you upfront that’s what we’re doing. Let’s figure out what the job actually needs, then we’ll talk materials.

FAQs – ES Windows Construction in Los Altos
Can you repair fogged ES Windows insulated glass units without replacing the entire window?
Yes, in most cases we can. If the frame and sash are sound, we replace only the failed IGU. We pop the glazing stops, cut out the old unit, and install a new sealed unit with matching low-E coating. We’ve done this on many ES Windows 6000 Series units in Los Altos where the argon had leaked out. If the frame is corroded or the sash is racked, then replacement becomes the smarter money. Call (833) 589-8103 and we’ll tell you which route applies.
How does Los Altos’ tree-protection ordinance affect my ES Windows replacement project?
If you have a heritage coast live oak within the drip line of the work area, the city will likely require root-zone fencing and may restrict excavation. That can dictate where we stage materials, where a lift can sit, and how we handle debris paths. We’ve done enough Los Altos ES Windows jobs to factor the tree survey into the estimate, so the permit doesn’t surprise you later.
Are ES Windows products suitable for the Los Altos climate, and what failures should I watch for?
They are, with the caveat that any window installed in the 1990s has now weathered twenty-plus years of Los Altos rain seasons and summer heat. The main failures we see are IGU seal failure and sill flashing leaks on the storm-facing sides of homes. If your glass is fogging or you see water staining under the window after a heavy rain, don’t wait. The fix is cheaper before the wall framing starts soaking it up.
Do you offer emergency repair for ES Windows damaged by storms or falling tree limbs?
We do. Los Altos gets its share of winter windstorms, and a limb through a window can’t wait. We’ll board and secure the opening, then order the replacement IGU or full unit. The time frame depends on whether the glass is stocked or has to come from the ES Windows supply chain. Call (833) 589-8103 and we’ll get it handled.
What is the typical cost to replace ES Windows in a Los Altos home?
Most Los Altos ES Windows replacement projects fall between $4,500 and $15,000, depending on how many units, the series, and whether you’re stepping up to impact-rated glass. Impact window installation runs $8,000 to $25,000 on larger homes. Your exact number depends on the house. Call (833) 589-8103 for a free line-item estimate.
