Why Los Angeles Homeowners Choose ES Windows Construction
We provide Es Windows repair in Los Angeles, from Mid-Century moderns in the hills to Spanish-style remodels in the Valley. Our crews work on ES70, ES45, ESL50, and ES900 series windows and doors every month, so we know exactly how these frames behave in our local climate: intense UV on south-facing walls, salt air near the coast, and Santa Ana wind-driven grit that chews through cheap weatherstripping. We are not affiliated with or authorized by ES Windows, and we will tell you that straight. Call (213) 277-6578 for a written estimate before any work begins.
The difference with our ES Windows work comes down to this: we give you a number first, then pick up the tools. Every ES Windows job gets a written price before we touch the window, a real arrival window, and the 365-Day Done Right Promise in writing. If the repair fails inside a year, we come back and make it right at no charge. No service call fee on that return visit, either.
Why Trust Penhallow Remodeling Los Angeles for Your ES Windows Construction?
Our technicians have spent real time pulling apart ES Windows frames, and that matters when the problem is not obvious from the outside. Trevor Nash, our owner, grew up in the Crenshaw district and studied construction technology at Los Angeles Trade-Technical College before spending nearly two decades on residential and light commercial jobs across the Basin. He has seen enough bowed interlock rails and seized roller assemblies to know the difference between a fifteen-minute hardware swap and a frame that needs to be replaced. He is the one who set our standard: show up in the window we gave, explain the repair in plain English, and leave the opening cleaner than we found it.
We are an independent ES Windows service provider. We do not claim factory authorization, and we never will. What we offer instead is hands-on familiarity with the brand’s aluminum and vinyl lineups, warranty-safe repair practices, and a written guarantee behind every job. That guarantee is part of The Kingswell Way, the operating standard we have followed since 2004: say the price before the work, show up when we said we would, and stand behind the finished job. Each Penhallow location is independently owned and operated, and our Los Angeles location answers to that same standard.

Common ES Windows Construction Problems We Fix in Los Angeles
We see the same handful of ES Windows failures repeat across Los Angeles, and most of them trace back to two things: sun exposure and salt air. Here are the five most common issues we repair, with the model lines where they typically show up.
- Warped or bowed interlock rails on ES70 sliders: The ES70 Series is thermally broken aluminum, which is a solid window, but the interlock rails on large south-facing sliders absorb brutal direct sun for years. The aluminum expands and contracts hundreds of times, and eventually the rail bows just enough that the panels do not seal tight, You feel a draft, hear road noise, and see daylight through the interlock. We re-align or replace the rail and often add a deeper interlock weatherstrip to restore the seal.
- Failed thermal breaks on ES70 fixed units: In coastal zones like Playa del Rey, we regularly pull ES70 fixed windows that are fogging and sweating every cool morning. The thermal break, which is a polyamide strip that separates the inner and outer aluminum, separates from the extrusion after 15 to 20 years. Once that bond fails, the window conducts heat and the interior frame sweats. This is a replacement job, not a patch. We source original ES70 sash replacements and re-glaze the unit, then re-seal the stucco returns properly.
- Stripped or frozen roller assemblies on ES45 sliding doors: The ES45 Series is non-thermal aluminum, and its sliding doors pick up salt and fine sand in beach neighborhoods. That grit works into the nylon rollers, the bearings seize, and the door jumps the track or refuses to move. We see this on nearly every ES45 sliding door that has faced years of west sun and coastal wind. We replace the rollers with original-style components and re-align the track so the door glides again.
- Cracked vinyl corners on ESL50 replacement windows: The ESL50 Series is the vinyl replacement line, and when the original installers shimmed the frame unevenly, the corners carry stress they were not designed for. After enough hot summers, the vinyl corner welds crack. Homeowners often assume the whole window is shot. It is not. We can sometimes reinforce and re-seal a corner, but if the frame is out of square, we will tell you replacement is the honest call.
- Hardware and weatherstripping fatigue across the line: Lock sets, keeper strikes, and weatherstripping on ES Windows are proprietary, not universal hardware. The lock stops engaging, or the weatherstripping flattens and the window whistles during Santa Ana winds. We replace these with factory-original ES parts whenever they are reasonably available, because aftermarket lock sets on these frames never seat correctly.
ES Windows Parts & Our Repair-vs-Replace Approach
For ES Windows, we use factory-original ES parts when we can get them. Lock sets, rollers, and weatherstripping on ES70, ES45, and ESL50 frames are proprietary geometry, not generic hardware store stock. Gambling on aftermarket versions usually means the lock binds or the roller does not seat, and then you are paying twice for the same repair. When original hardware is discontinued or backordered, we source close-match aftermarket components we have tested for fit and durability, and we show you the part difference before we install it. You decide with the part in your hand.
On the bigger question, repair versus replace, our answer depends on the frame. A hardware swap or weatherstrip replacement is a sensible repair. A failed thermal break on an ES70 fixed unit, or a corroded-through aluminum frame on a coastal home, is not worth patching. A short-term fix on a failing frame delays the inevitable and costs more in the long run. We will tell you which side of that line your window is on, and we will put the price for either path in writing before any work starts.
Our ES Windows Service Process – Step by Step
- 1
Diagnosis: We schedule a real arrival window, not a four-hour guess. Our tech inspects the window, identifies the specific failure (a seized ES45 roller, a separated ES70 thermal break, a cracked ESL50 corner weld), and explains the repair in plain English.
- 2
Written price: Before any work starts, you get a written price for the repair or replacement. That number covers parts and labor. The number on day one is the number on the invoice.
- 3
Repair or replacement: We bring the correct ES Windows parts or full replacement units, remove the old frame or components carefully, and install using the same flashing and sealing methods the opening needs for Los Angeles conditions: sun-rated sealants, proper shimming, and stucco returns sealed with backer rod and elastomeric caulk.
- 4
Testing and cleanup: We cycle the window or door several times to verify operation, check the seal, and confirm the lock engages fully. Then we leave the job site clean, with no glass shards or old weatherstripping left behind.
- 5
Warranty: Every ES Windows repair and installation gets our written 365-Day Done Right Promise. If the work fails inside the guarantee period, we return and fix it at no charge, including a free second visit. No re-inspection fee, no argument.
The standard is simple: we put the price and the guarantee in writing before we pick up a tool. Call (213) 277-6578 if you want to talk through a specific window issue.

AfterES Windows Products We Service & Install in Los Angeles
We service and install the full ES Windows lineup that appears in Los Angeles homes:
- ES70 Series: Thermally broken aluminum windows and doors, common in custom and higher-end Los Angeles homes. We handle interlock rail repairs, thermal break failures, lock replacements, and full unit replacements.
- ES45 Series: Non-thermal aluminum windows and sliding doors, frequently used in older and mid-range construction. We replace rollers, tracks, latches, and weatherstripping, and we install new ES45 units where an opening needs a direct replacement.
- ESL50 Series: Vinyl replacement windows. We handle corner weld repairs, sash balances, locks, and full-frame replacements.
- ES900 Series: Heavy commercial aluminum, which shows up in mixed-use buildings and larger residential projects. We service and replace these on a case-by-case basis.
We keep common ES hardware in local stock for faster turnaround: rollers, lock sets, keepers, and weatherstripping for ES70 and ES45 lines. For larger components and full sashes, we order from our supplier network and get units to your house on a schedule we agree on in advance.
We Also Service These Brands
ES Windows is a big part of our window and door work, but we are not a single-brand shop. Our General Contractor services also include KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler fixtures. If your project involves a window replacement plus a kitchen or bath update, one crew can handle the whole scope without you coordinating three different contractors.
FAQs – ES Windows Construction Service in Los Angeles
No. We are an independent ES Windows service provider, not a factory-authorized dealer or installer. That means we are not bound by factory pricing schedules or limited to factory parts channels. It also means we are free to tell you honestly when a repair is worth doing and when replacement makes more sense. Our relationship is with you, not the manufacturer.
We use factory-original ES parts whenever they are reasonably available. ES Windows lock sets, rollers, and weatherstripping are proprietary, and aftermarket versions generally do not fit correctly. When a part is discontinued or backordered, we source a close-match aftermarket component that we have tested, and we show you the part difference before installing it. You approve the part before it goes in.
In most cases, a fogged or failed ES70 fixed unit needs new sashes, not just glass. The failure is not the glass itself; it is the thermal break separating from the aluminum extrusion. Replacing the glass alone leaves the failed thermal break in place, and the window keeps sweating. We source original ES70 sash replacements and re-glaze the entire unit, which fixes the problem at the source. Call (213) 277-6578 and we can inspect your specific units and give you a written price for the right repair.
Yes. We see it on almost every ES45 sliding door that has faced the west sun in Sherman Oaks or Studio City. The nylon rollers get brittle from heat and UV exposure, the bearings seize, and the door jumps the track or drags. We replace them with original-style rollers and re-align the track, which restores smooth operation for years. If the track itself is worn or corroded, we will show you that before any work begins.
ES Windows offered factory anodized finishes in bronze, white, and clear, along with painted finishes on some lines. When we replace a unit or a sash, we match the finish as closely as the current ES product line allows. For discontinued finishes on older units, we work with our finishing partners to get a close match, and we will show you a finish sample against your existing frame before ordering. An exact match on a 30-year-old anodized frame is not always possible, and we will say so plainly rather than promise a perfect match that does not happen.
They can be, with the right series. The ES70 Series, with its thermal break, is a better coastal choice than the non-thermal ES45, because it resists condensation and conducts less heat. But even ES70 frames need proper sealing and maintenance against salt air, which accelerates corrosion on aluminum. If you are planning a coastal remodel and weighing window options, call (213) 277-6578. We will walk through what holds up near the water, what does not, and what the install would cost in writing before you commit.
ES Windows repair and replacement pricing in Los Angeles depends on the scope, but here are market-calibrated ranges for the work we do:
| Service | Typical Los Angeles Range |
|---|---|
| Impact Window Installation | $9,440 – $29,500 |
| Window Replacement | $5,310 – $17,700 |
| Specialty Roofing (e.g., window-to-roof flashing, skylight deck) | $4,130 – $12,980 |
A simple hardware repair, like a lock set or roller replacement, typically runs far less than a full window replacement, often in the low hundreds. A thermal break failure on an ES70 fixed unit, where the whole sash needs replacing, lands higher. The honest way to know is to have us look at the window and give you a written number. Call (213) 277-6578 for a free estimate, and the number we give you is the number you will pay.
Almost never. ES Windows lock sets and keepers are replaceable components. We carry common ES70 and ES45 lock hardware in local stock, and a broken lock is typically a fifteen-minute repair, not a window replacement. The exception is when the lock failure is a symptom of a larger problem, like a bowed interlock rail that has thrown the sash out of alignment. We will inspect the window, tell you what is actually wrong, and give you a written price for the fix. Call (213) 277-6578 to schedule that inspection.
