We provide independent ECO Window Systems construction service across Claremont, including replacement, reglazing, hardware repair, and full window and door retrofit work. What makes our ECO Window Systems work different here is simple: we understand Claremont’s design review culture and its older housing stock, so we match period-appropriate profiles instead of dropping in whatever fits the rough opening.

Why Claremont Residents Choose Us for ECO Window Systems Service
We’ve installed, retrofitted, and repaired ECO Window Systems in Montclair, Claremont, and nearby cities long enough to know how these vinyl frames and glazing assemblies actually behave under San Gabriel Valley sun, Santa Ana wind, and winter rain. Not what the spec sheet claims. What the units do after five or ten years facing west toward the mountains. That’s the knowledge that matters when you’re deciding whether to reglaze a fogged slider or replace it outright.
Nate Calloway, who owns Sycamore Contractors, grew up in Temecula’s Redhawk neighborhood and spent two decades running crews across Southwest Riverside County before building Sycamore into a full-scope general contracting firm. He learned the fundamentals at Palomar College’s construction technology program, then learned the rest on real job sites where an out-of-square 1920s wall doesn’t care about your spec sheet. His approach carries through every ECO Window Systems job we take in Claremont: figure out what’s actually failing, explain your options plainly, and do the work so it holds up. We’re an independent contractor, by the way. We are not authorized, sponsored, or warranty-backed by ECO Window Systems, and we’ll be straight with you about when OEM parts make sense and when a quality aftermarket glazing unit is the better call.

Common ECO Window Systems Construction Problems We Solve in Claremont
- Vinyl frame and sash distortion on west- and south-facing elevations. Claremont’s inland valley heat is relentless, and sustained UV on a west-facing wall will eventually distort ECO vinyl sashes. You’ll notice it as a slider that won’t latch, a meeting rail gap you can see daylight through, or a single-hung that binds partway up. We see this most often on homes near the Colleges where windows face the afternoon sun with no shade.
- Failed perimeter seals and degraded glazing gaskets. The dust and Santa Ana winds that roll down from the San Gabriels push fine grit into every seal gap. Once the perimeter seal on an ECO unit fails, winter rain follows the same path. What starts as a little dust on the sill becomes water staining behind stucco or wood trim, often hidden until the trim itself starts to rot.
- Fogged dual-pane insulated glass on older ECO sliders and picture windows. Seal failure on 15-plus-year-old ECO units facing the mountains is the single most common call we get in Claremont. The glass fogs permanently, the thermal performance drops, and no amount of cleaning fixes it. The frames are often still sound, which means reglazing is frequently the smarter move than full replacement.
- Tilt latch, balance, and roller wear on units installed into out-of-square openings. Claremont’s early-1900s Craftsman and Spanish Colonial Revival homes have settled walls. A window that was forced square at install will wear its hardware unevenly. We replace worn tilt latches, roller assemblies on sliders, and balances with OEM parts where the ECO profile is still available, and we correct the opening where needed so the new hardware isn’t fighting the same war.
- Dry rot in wood trim surrounding ECO units on older homes. This one is particularly Claremont. The combination of unchecked UV on old-growth redwood or Douglas fir trim and water intrusion at failed window seals creates rot pockets that spread fast. We rebuild the rotted trim and re-flash the opening so the repaired elevation still reads consistent with the original house, which matters a great deal when design review is involved.
ECO Window Systems Service in Claremont: What Local Conditions Mean for Your Equipment
Claremont’s historic-preservation culture changes how window work gets done here, and it changes how we approach ECO Window Systems service in ways that just don’t apply in neighboring Pomona. Near the Village and the five Claremont Colleges, many older homes sit on small lots where any window replacement or addition work runs through the city’s design review process. That means you can’t always swap a wood-framed original for a standard white vinyl unit and call it done. The review body and your neighbors expect the new work to read as historically consistent, which often means matching original sightlines, trim profiles, and sometimes the look of original divided-light patterns. We’ve worked through that process enough times to know how to keep an ECO Window Systems retrofit approvable while still delivering modern thermal performance, and we bring the same care to ECO Window Systems service in La Verne. On a 1920s Craftsman near the Village in the 91711 ZIP, we pulled several fogged, hard-to-latch ECO vinyl sliders and found the sashes had distorted from years of west-facing sun while the wood trim around them had dry rot. We reglazed the units that still had sound frames, replaced the failed ones with profile-matched replacements, and rebuilt the rotted trim so the elevation still read consistent with the rest of the house. That’s the Claremont difference: the window work has to serve two masters, and we’ve learned how to answer both.
ECO Window Systems Models & Products We Service in Claremont
We service the full range of ECO Window Systems product lines you’ll find in Claremont homes: vinyl single-hung replacement windows, vinyl sliding patio doors, fixed and picture windows, horizontal sliders, and the dual-pane low-E retrofit units that went into so many older Claremont remodels over the past two decades. Our parts approach is straightforward: when the ECO profile is still available, we use OEM replacement sash, glass, and hardware. When OEM parts are discontinued or sitting on a long lead time, we match quality aftermarket glazing units and balance systems that perform to the same spec. On units with sound frames but failed glass, we recommend reglazing over full replacement. When the frame is distorted or the rough opening itself is failing, replacement is the honest call, and we’ll tell you that up front. Our ECO Window Systems sales & service team keeps common Claremont retrofit profiles and glazing units moving quickly so you’re not waiting weeks on a fogged slider.

AfterECO Window Systems Service Pricing in Claremont
Window work in Claremont prices out differently depending on whether you’re reglazing a fogged unit, replacing a single window, or cutting new openings as part of an addition. Here’s what we quote against:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
| Home Addition | $45,000 – $130,000 |
What moves the number is the condition of the rough opening, whether design review requires profile matching or custom trim work, and how many units are involved. A single reglaze on a sound frame is a fraction of the cost of full replacement. A whole-elevation replacement on a hillside-adjacent home with fire-resistant detailing will land toward the top of the range. Every estimate we give in Claremont is free, and we walk you through the line items before you commit to anything. Call (877) 265-6284 to schedule yours.

FAQs – ECO Window Systems Construction in Claremont
Yes, in most cases we can reglaze the failed insulated glass unit and keep your existing ECO frame, provided the frame itself is still sound and square. This is usually the right call on Claremont homes where the window profile needs to stay consistent for design review or where the frame is fine and only the seal failed. We’ll inspect the unit, check the frame for distortion, and tell you plainly if reglazing will hold or if replacement is the better long-term move. Call (877) 265-6284 for an exact quote.
Often yes, and it depends on the age of the home, the historic district designation, and how visible the change is from the street. Homes near the Village and the Colleges frequently fall under design review that requires window replacements to match original profiles, sightlines, and sometimes material appearance. We’ve navigated Claremont’s review process enough to prepare the submittal correctly the first time, which saves you weeks of back-and-forth and a possible denial. We apply the same rigor to ECO Window Systems service in San Antonio Heights.
That’s thermal distortion of the vinyl sash, and it’s common on south- and west-facing elevations in Claremont’s inland valley heat. Sustained UV and high surface temperatures cause the vinyl to expand and warp slightly, which binds the sash in its track and leaves gaps at the meeting rail. Sometimes the fix is a hardware adjustment; sometimes the frame has permanently distorted and replacement is the honest fix. We’ll tell you which one you’re dealing with after a look at the unit.
They can be, particularly on hillside-adjacent properties in Claremont where wind loads and fire-resistant detailing matter more. Impact-rated replacement isn’t always necessary for every home, but if you’re on an exposed western or northern slope that catches the full force of Santa Ana events, upgrading to impact glazing while replacing old ECO units makes a lot of sense. We’ll assess your exposure and give you a straight answer, not a sales pitch. Estimates are free at (877) 265-6284.
Yes. Small lots near the Colleges mean additions often run tight to the property line and require careful placement of new window openings for privacy, light, and design-review approval. We handle home additions from framing through finish, and we integrate ECO Window Systems units or profile-matched replacements into the new envelope so the addition reads like it belongs to the original house. Call (877) 265-6284 and we’ll walk your lot and talk through what’s feasible.
