ECO Window Systems Construction in El Granada, CA | Ashford Contractors
We provide independent ECO Window Systems construction, replacement, and repair across El Granada and nearby areas like Moss Beach ECO Window Systems service, from full window retrofits to hardware swaps on the older aluminum units still common in beach cabins here. What makes our ECO work different in El Granada is that we deal with the Coastal Commission review on ocean-facing lots before a single unit gets ordered, and we stock marine-grade fasteners and flashing that stand up to the salt fog coming off Pillar Point. If your ECO windows are sticking, leaking, or just worn out, call Ashford Contractors at (877) 752-3868 for a free estimate. We are not a manufacturer-authorized dealer and we make no claim to be one. We are a general contractor who works on these systems weekly along the San Mateo County coast.
Why El Granada Residents Choose Us for ECO Window Systems Service
Most window contractors on the Peninsula see ECO Window Systems in Half Moon Bay and nearby coast towns occasionally. In El Granada, we see them constantly, because so many of the mid-century beach bungalows and newer custom homes between Highway 1 and the harbor still carry these vinyl and aluminum units. Our crews know how ECO single-hung and double-hung replacement windows behave after a decade of marine-layer humidity, and we know which series tend to fail at the hardware first rather than the glass.
Glen Mossier, our owner at Ashford Contractors, grew up in Foster City and trained in construction technology at Skyline College, and he has spent two decades working structural remodels along the San Mateo County coast. He taught our window crews a rule that applies doubly in El Granada: build it right the first time, and you won’t be rebuilding it in ten years. Around here, that means stainless flashing, properly lapped weather barrier, and gaskets that actually match the extrusion, because salt air does not give you a grace period.
We use OEM ECO Window Systems glazing gaskets, weatherstripping, and hardware wherever they are still available, because a generic gasket never seats the same way in an ECO extrusion. Where the factory hardware was never suited to ocean exposure in the first place, we move to marine-grade stainless aftermarket parts. That combination keeps your windows sealing like the original design while surviving conditions the original spec did not anticipate.

Common ECO Window Systems Construction Problems We Solve in El Granada
- Frozen latches and rollers on ECO vinyl sliders. The plated hardware on horizontal sliders and patio doors pits within a few seasons of Pacific salt fog. Homeowners near the harbor report latches that will not throw and rollers that grind. We replace them with marine-grade stainless and re-bed the track, which solves the corrosion problem permanently.
- Interior sill staining on flat-lot homes. Marine-layer humidity and wind-driven rain push past worn glazing gaskets and clogged weep holes on the low-lying lots between Highway 1 and the harbor. The result shows up as brown staining at the sill corners. Usually the frames and glass are still sound, and a proper gasket replacement plus weep-hole reaming stops it.
- Galvanic corrosion on older aluminum-series ECO frames. Mid-century beach cabins in El Granada often still have the aluminum series ECO windows from the 1960s and 1970s. Where steel fasteners and flashings meet the aluminum frame, galvanic corrosion loosens anchors at the rough opening. We drill out the corroded hardware, re-anchor with stainless, and re-flash the surround.
- Leaking nailing fin and flashing seals on ocean-facing walls. Winter storm surf drives rain horizontally into west elevations. When the integrated nailing fin or the flashing tape fails, water wicks behind the frame into old framing. We pull the unit, repair any rot at the rough opening, re-flash for wind-driven rain, and reinstall or replace depending on frame condition.
- Chalky, UV-degraded vinyl on older ECO units. Fog softens the sun but the UV still gets through, and vinyl frames exposed for decades turn chalky and brittle. Once the extrusion starts powdering, re-sealing will not hold. We tell clients straight: this is a replacement job, not a repair, and we can match the opening with a current ECO vinyl unit or an impact-rated window if the lot is in a storm-exposed zone.
ECO Window Systems Service in El Granada: What Local Conditions Mean for Your Equipment
The single biggest variable in El Granada that inland Peninsula contractors never face is the Coastal Commission gate. Lots near the harbor and the bluffs sit inside California Coastal Commission permit jurisdiction, and many also carry flood or coastal-zone review overlays. If a window replacement or home addition changes an opening on an ocean-facing elevation, the Coastal Commission may need to review the scope before the ECO units can even be ordered. That review does not apply to a like-for-like window swap on an inland lot in San Carlos or Belmont, but in El Granada it is a routine part of the job for a meaningful share of the housing stock. We handle that sequencing as part of the construction service: permitting first, unit ordering second, install when the coastal-zone review clears. Homeowners who order windows first and discover the permit gate later end up with units sitting in a garage for months. We have seen it happen.
Separately, the salt fog off the Pacific corrodes exposed galvanized hangers, nails, and window hardware at a pace that surprises people who moved here from the East Bay. The plated parts on ECO slider and hung units are usually the first casualty, well before the vinyl or glass shows any wear. That is why we stock stainless fasteners, marine-grade flashing, and OEM gaskets in our El Granada service vehicles rather than making a run to the supply house on every job.
ECO Window Systems Models & Products We Service in El Granada
We work on the full span of ECO Window Systems product families found in El Granada housing stock. That includes vinyl single-hung and double-hung replacement units, vinyl sliding patio doors, the older aluminum series windows common in mid-century beach cabins, and horizontal slider and fixed-picture combinations on newer custom homes. When factory parts are still produced, we order OEM ECO gaskets, weatherstripping, and latches so the seal and fit match the original extrusion exactly. When the original hardware was never up to coastal conditions, we source aftermarket stainless or marine-grade replacements that hold up better here. For full window replacement or impact window installation, we are also an established provider through our general contracting scope, see ECO Window Systems sales & service for the wider brand overview.

FAQs – ECO Window Systems Construction in El Granada
Yes, if your lot sits inside California Coastal Commission permit jurisdiction, which is common near the harbor and the bluffs, and if the replacement changes the size, number, or configuration of openings on an ocean-facing elevation. A like-for-like replacement of the same window in the same rough opening often clears without coastal review, but every property is different. Our team checks the specific parcel before ordering units. Call (877) 752-3868 and we will tell you where your lot stands.
It is the salt fog. Plated hardware on ECO slider tracks and latches pits and corrodes after a few seasons of direct Pacific exposure, especially on the flats between Highway 1 and the harbor where the marine layer sits all summer. We swap in marine-grade stainless hardware and re-bed the track, which fixes the problem indefinitely without touching the glass or vinyl frame.
Yes, when the frames are sound and the failure is a worn glazing gasket, a fogged insulated glass unit, or pitted hardware. We will only recommend full replacement when the vinyl is chalky, the aluminum frame is corroded beyond re-sealing, or the rough opening itself has structural problems. A repair is usually a fraction of replacement cost, and we will show you both options with straight numbers.
Fog equals persistent moisture. We detail every opening in a home addition with sealed flashing, properly lapped weather barrier, and weep paths sized for wind-driven rain, not just incidental splash. On a mid-century beach cabin addition in the flats between Highway 1 and the harbor, our crew found ECO vinyl sliders with frozen latches and rollers pitted from salt fog and a leaking glazing gasket on the west elevation. We swapped in OEM gaskets and marine-grade stainless hardware, re-flashed the rough opening for wind-driven rain, and left the original vinyl frames and glass in place. The client kept the cabin’s openings and gained a sealed, storm-ready wall without a full replacement. That is the standard we build to on every El Granada addition.
Window replacement on an ECO unit typically lands between $4,500 and $15,000 depending on the number of units, access, and whether coastal-zone review applies. Impact window installation runs $8,000 to $25,000, and an addition that includes new ECO window packages starts around $45,000 and can reach $130,000 for full second-story or bump-out work.
