Why Woodland Hills Homeowners Choose ES Windows Construction
Mason Remodeling Co Woodland Hills provides independent ES Windows construction, repair, and replacement service across Woodland Hills, CA, and neighboring communities including Es Windows service in Brentwood. We’re not a factory-authorized dealer, and we won’t pretend to be. What we are is a full-service construction company that installs, services, and integrates ES Windows into kitchen, bathroom, and whole-home remodels every week, and we’ve solved the site-specific fit and finish problems these windows present in hillside and canyon homes throughout the 91364 and 91367 ZIP codes. Call (831) 290-6866 for a written estimate on any ES Windows scope, from a single casement lock rebuild to impact-rated replacement packages.
What separates our ES Windows work from a standard glazing contractor is the construction context. We’re not just swapping glass. We’re flashing openings correctly on mid-century ranch homes, rebuilding framing around racked picture windows on stucco exteriors, and replacing fogged IGUs inside kitchens that are being fully remodeled anyway. That changes the conversation: repair vs. replace, OEM vs. aftermarket, and how the window performs inside the larger project. Isaac Pruett, our owner, learned his trade foundations at Los Angeles Trade-Technical College and has spent years working the neighborhoods around Warner Center and the hills south of Ventura Boulevard. He’s seen what Woodland Hills heat, Santa Ana winds, and expansive soils do to window frames and flashing over time.
Why Trust Mason Remodeling Co Woodland Hills for Your ES Windows Construction?

Here’s what you need to know before anyone touches your ES Windows: who is coming, what it will cost, and what is guaranteed. Every Mason Remodeling Co Woodland Hills technician is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge. Before the visit, you receive the technician’s name and photo. That’s the Threshold Standard, and it applies to every job we run in Woodland Hills, whether we’re replacing one window or running a full kitchen remodel with ES Windows integrated into the scope.
On the ES Windows side specifically, our crews know the product lines well enough to have opinions about them. We know where Series 70 frames tend to bind, why early Series 80 sliding doors fog between the panes, and when a multipoint casement lock is worth rebuilding versus replacing. We use factory-matched ES Windows glazing and hardware where available, and we’ll tell you plainly when a quality aftermarket part makes more sense. Written pricing comes before any work starts, and every completed project carries a written guarantee stating exactly what’s covered and for how long: 365 days from the completion date. If a repair or installation fails within that year, we fix it at no cost under our 365-Day Done Right Promise. No dispute process, no conditions. Isaac says it plainly: tell me what you need done. I’ll tell you what it takes and what it costs. Then we get to work.

Common ES Windows Construction Problems We Fix in Woodland Hills
- Warped or swollen sashes that bind in the frame after winter rains. This shows up most often on older Series 70 units where the original flashing was never installed properly or has since degraded. Woodland Hills gets intense heat that dries frames out, then winter moisture causes expansion. The result is a window that won’t close without force. We repair the frame, replace weatherstripping, and reflash the opening with modern sill pans where needed.
- Fogging between panes from failed edge seals. Early Series 80 sliding doors are the usual suspects here. The Insulated Glass Unit (IGU) loses its seal over time, and moisture gets trapped between the glass. You’ll notice it most in the morning before the sun burns off condensation. The fix is an IGU replacement, not a frame replacement, which saves real money when the frame itself is still square and sound.
- Stripped or loosened multipoint lock hardware on casement models. Casement windows rely on that multipoint lock to compress the sash against the weatherstripping. When the mechanism strips or loosens, you get air leaks, drafts, and a window that doesn’t seal. We rebuild these with quality aftermarket multipoint locks on older ES Windows series where OEM lead times or warranty restrictions make factory parts impractical.
- Damaged exterior cladding from stucco water runoff. We see this on fixed picture windows on stucco homes throughout Woodland Hills. Water runs down the stucco, sits on the aluminum cladding, and eats through the finish over years. Once the cladding is compromised, the underlying frame is exposed. We repair or replace the cladding and address the drainage issue so it doesn’t repeat.
- Racked frames from hillside settling. Woodland Hills homes on expansive soils move. A window frame that’s been racked out of square won’t operate properly no matter how much hardware you throw at it. When we find a racked ES Windows frame, we’re honest: the unit gets replaced, not patched. Patching a structurally compromised frame is a waste of your money.
ES Windows Parts & Our Repair-vs-Replace Approach

We carry factory-matched ES Windows glazing and hardware locally where available. For older series, especially Series 70 units that are no longer in active production, factory lead times can stretch months. When that’s the case, we use high-quality aftermarket multipoint locks and weatherstripping that meet or exceed the original spec. We’ll tell you which we’re using and why, and we’ll price it out before work starts.
The repair-vs-replace decision comes down to two questions: is the glass sound, and is the frame square? Sound glass in a square frame gets repaired: new hardware, new weatherstripping, new flashing if needed. Fogged glass in a square frame gets a new IGU. A racked frame, or a frame with significant rot or structural damage, gets replaced as a complete unit. We’d rather tell you the straight answer than sell you a repair that fails in eighteen months.

Our ES Windows Service Process – Step by Step
- 1
Diagnosis. We inspect the window, the frame, the flashing, and the surrounding wall assembly. For fogged IGUs, we confirm the seal failure and measure the unit. For hardware problems, we test the lock, the hinges, and the weatherstripping. For racked frames, we check for square and look for signs of foundation movement behind the opening.
- 2
Repair or install. We rebuild locks, replace IGUs, reflash openings, or install complete new ES Windows units depending on what diagnosis revealed. Every repair addresses the root cause, not just the symptom. That means new sill pans under Series 70 picture windows, not just new caulk.
- 3
Test. We operate the window through its full range of motion, check compression on the weatherstripping, and verify no air or water infiltration. On new installs, we check for square, plumb, and proper sealant application.
- 4
Warranty. Every completed job carries our written 365-Day Done Right Promise. If the repair or installation fails within a year, we return and make it right at no cost to you. The terms are written plainly: what’s covered, what’s excluded, and for how long.

AfterES Windows Products We Service & Install in Woodland Hills
We service and install across the ES Windows product range: the Series 70, Series 80, Series 90, and the Acoustic Series.

We stock common hardware, weatherstripping, and glazing components locally for faster turnaround in Woodland Hills and Es Windows in Woodland Hills surrounding areas, and we can source the rest on predictable lead times.

We Also Service These Brands
While this page is about ES Windows, Mason Remodeling Co Woodland Hills offers General Contractor services, not single-brand glazing. We specify and install KraftMaid and other cabinet lines, Cambria and Silestone countertops, and Kohler fixtures across the same kitchen, bath, and whole-home remodels where ES Windows show up. That breadth means one crew, one schedule, and one written price for scopes that touch multiple product lines.
FAQs – ES Windows Construction Service in Woodland Hills

Fogging between panes means the edge seal on the Insulated Glass Unit has failed, allowing moisture inside the sealed air space. It’s a common failure on older Series 70 units, especially in Woodland Hills where hot summers and cool winter mornings put constant stress on the seal. The fix is an IGU replacement, not a whole new window. Call (831) 290-6866 for an exact quote on your specific unit.
Yes, in most cases. If the casement frame is square and the glass is intact, we can rebuild the multipoint lock mechanism with a factory-matched or high-quality aftermarket part, and the window will close and seal properly again. We only recommend full replacement when the frame itself is damaged or racked.
Both. We handle standalone ES Windows repair and replacement, and we also integrate window work into kitchen, bathroom, and whole-home remodels throughout Woodland Hills and nearby areas like Es Windows in Sherman Oaks. If your remodel includes new ES Windows, we can run the entire scope under one written price and one schedule.
That depends on what’s causing the binding. If the frame has absorbed moisture and swollen, it may be a flashing or drainage issue rather than a manufacturing defect. We’ll diagnose the real cause before recommending any repair. As an independent service provider, we can’t make warranty determinations for ES Windows, but we can document what we find so you can pursue a claim if one exists.
Repair addresses specific components: hardware, weatherstripping, IGUs, cladding. Replacement is a complete new window unit, frame and all. We repair when the frame is sound and square. We replace when the frame is racked, rotted, or structurally compromised. Honest to a fault: we won’t sell you a patch job on a frame that needs to go.
Window replacement per opening typically runs $4,500 to $15,000. Impact window installation for a full single-story perimeter runs $8,000 to $25,000. A kitchen remodel that includes ES Windows replacement runs $14,000 to $45,000. These are Woodland Hills market ranges, and your exact price comes in a written estimate before any work starts. Call (831) 290-6866 to schedule yours.
