ECO Window Systems Construction in Chinatown, CA | Framework Contractors
We provide independent ECO Window Systems construction, replacement, and repair across Chinatown (94133), and the one thing that separates our work here from anywhere else is logistics. Pre-assembling and hand-trucking ECO units through storefronts and light wells isn’t a workaround for us, it’s the standard. We know the brick-and-timber buildings, the soft-story racks, and the salt air that eats aluminum frames on Jackson and Stockton. Our team works around ground-floor businesses that can’t close for a day, let alone a week.
Framework Contractors has spent years retrofitting ECO Window Systems units into Chinatown’s dense residential-over-commercial blocks. We’re not manufacturer-affiliated. We’re not an authorized dealer. We’re an independent general contractor that draws from 50+ building product brands, and ECO Window Systems sits in our window and door program alongside PGT, CGI, and Therma-Tru. One contractor, every system. From the roof down to the foundation. Call (844) 681-3590 for a free estimate on any ECO Window Systems project in Chinatown.
Why Chinatown Residents Choose Us for ECO Window Systems Service
Noel Carbajal, our owner, grew up helping his uncle patch stucco and reroof porches in Santa Ana before studying construction technology at Santiago Canyon College. He’s spent the better part of three decades building and remodeling across Orange County and beyond, and his two sons have both worked summers on his crew. One has stayed on full-time. That’s the kind of company we are. The people quoting your job are the people who know how to do it.
Chinatown property owners tend to call us after a previous contractor said the windows were fine. Fogged glass gets written off as cosmetic. A sticking sash gets blamed on the tenant. We don’t work that way. We diagnose ECO Window Systems failures in the context of the building behind them, because in Chinatown the building is rarely square, rarely dry, and rarely forgiving. Your materials, our craftsmanship. We work with the brands you already trust, and ECO Window Systems is one we service weekly in 94133.

Common ECO Window Systems Construction Problems We Solve in Chinatown
- Corroded aluminum frames and hardware on fog-facing elevations. Salt-laden air off the Bay is relentless on north- and west-facing ECO Series 5000 aluminum single-hungs. We see pitted frames, seized locks, and corroded track rollers on Grant and Stockton buildings where the fog lingers longest. We replace hardware with stainless or coated components and prep frames before re-installation.
- Failed perimeter seals on original single-pane glass. Older ECO aluminum units often lose their seal and start fogging, then water creeps behind the sash and into the rough opening. The glass is a symptom; the rot behind it is the problem. We pull the sash, assess the opening, and either re-glaze or replace the unit depending on what the frame tells us.
- Shifted and rotted rough openings in pre-1906 structural frames. In buildings that predate the 1906 quake or went up in the 1920s, decades-old ECO windows sit in openings that have torqued or rotted out. Air and water leak around the unit even though the window itself is intact. We rebuild the rough opening with treated lumber, flashing, and square it up before the new ECO unit goes in.
- Sticking sashes caused by soft-story racking, not bad windows. Tuck-under soft stories and unreinforced masonry shift under load, racking window openings out of square. ECO sashes bind, seals fail early, and the glass stresses. In Chinatown, sticking windows are frequently a structural signal, not a hardware problem. We check the opening, not just the sash.
- Staging and access constraints on zero-setback lots. Party-wall-to-party-wall buildings with no rear access mean every window replacement on Stockton or Jackson requires either a street-side ladder drop or a hoist through a light well. We pre-assemble ECO units at our shop and hand-truck them in to keep sidewalks clear and storefronts open.
ECO Window Systems Service in Chinatown: What Local Conditions Mean for Your Equipment
Chinatown sits inside San Francisco’s northeast corner, where pre-1906 and early-20th-century brick-and-timber buildings are shoehorned into narrow lots along Grant, Stockton, and Jackson. Most jobs here are seismic retrofits, soft-story upgrades, and interior remodels of dense multi-generational blocks, not ground-up construction. That means window openings get racked, flashed, and rotted in ways you won’t find with Mission District ECO Window Systems service or in the Sunset. The historic-district design review, Chinese-community land stewardship through family associations and benevolent societies, and San Francisco’s mandatory seismic and accessibility codes all layer onto a simple window replacement.
Here’s the detail no generic window page covers. Because Chinatown’s narrow lots and zero setback mean most window replacements require staging from the street or through light wells, we pre-assemble and pre-glaze ECO units at our shop so we can hand-truck them in and minimize the time a ladder or hoist blocks the sidewalk or a storefront. On Jackson Street, we replaced a set of fogged ECO Series 5000 aluminum single-hungs in a 1920s brick building where the original wood frames had rotted from years of marine moisture. We rebuilt the rough openings with treated lumber and flashing, then installed new dual-pane ECO units with stainless-steel screws to resist corrosion, hand-trucking each window through the ground-floor shop after hours so the business could stay open. That’s how you replace windows in Chinatown without costing a merchant a week of revenue.
Noel puts it plainly: “Build it right the first time – the second time costs twice as much and nobody’s happy.” In 94133, the second time always costs more because access is hard, permits are layered, and the building doesn’t wait for a convenient schedule.
ECO Window Systems Models & Products We Service in Chinatown
We work on the ECO Series 5000 Aluminum Single-Hung, the ECO Series 3000 Vinyl Double-Hung, and the ECO Series 8000 Sliding Glass Door. We also service older ECO aluminum units that predate the current model lines and are no longer in active production. Parts strategy is simple. We source OEM ECO Window Systems parts when they’re available for a precise fit. For obsolete models, we use quality aftermarket glazing and hardware that meets or exceeds the original spec. We’ll tell you honestly whether a repair makes sense or if replacement is the better long-term investment given your building’s conditions, because in Chinatown the building conditions always decide the answer.
We keep common hardware, seals, and glazing options staged for fast turnaround in 94133. ECO Window Systems sales & service is one part of our broader window and door program, which draws from seven manufacturers including impact-rated PGT and CGI alongside entry-door specialist Therma-Tru. Your materials, our craftsmanship.

FAQs – ECO Window Systems Construction in Chinatown
Can you replace just the glass in my ECO aluminum windows, or do I need full unit replacement? It depends on the frame and the opening. If the ECO aluminum frame is square, dry, and corrosion-free, we can re-glaze. If the perimeter seal has failed and water has been sitting behind the sash, or the rough opening has shifted, full unit replacement is usually the smarter investment. We’ll show you what we found and quote both options when possible. Call (844) 681-3590 for an exact assessment.
How do you handle window replacement on a building with a ground-floor business that can’t close? We pre-assemble at our own shop and hand-truck units through the shop or a light well, then stage outside business hours. On Jackson Street we’ve replaced full sets of ECO Series 5000 single-hungs after the merchant closed for the evening and had the storefront open by morning. The sidewalk stays passable, the business keeps running, and the windows get done.
Do I need a permit to replace my ECO windows in Chinatown? In most cases, yes. San Francisco’s building department treats window replacement in historic districts and pre-1906 buildings as regulated work, and your building may also sit inside a design-review overlay tied to family associations or benevolent society stewardship. We handle permits and inspections as part of our scope. Built to spec, not to shortcut.
My ECO windows are sticking and hard to open – is that a window problem or a building issue? In Chinatown, it’s frequently the building. Tuck-under soft stories and unreinforced masonry rack window openings out of square, which binds the sash and stresses the seals. We check the opening first. If the frame is square and the track is clean, we’ll tune the hardware. If the building moved, the window is telling you something else.
What’s the best way to protect new ECO windows from the salt air and fog? Hardware choice matters. We use stainless-steel screws and corrosion-resistant components on marine-facing elevations, and we flash the rough opening so water never gets behind the frame. Regular cleaning of the track and weep holes helps too. If you’re planning a full replacement soon, call (844) 681-3590 and we’ll spec the right materials before the fog eats anything else.
