CWS Construction in Montara, CA | Seaside Contractors
Seaside Contractors provides independent CWS construction service across Montara, CA (94037), from window and door repair to full garage conversions and impact-rated installations. We’re not a CWS dealer or authorized warranty shop – we’re a full-scope general contractor who knows exactly how CWS products age in Montara’s salt-and-sand air, and we spec fixes that outlast the factory defaults. If you own a CWS window, sliding door, or a Montara home with CWS-built openings, call us at (833) 589-8103 for a free estimate.
Why Montara Residents Choose Us for CWS Service
We tear into CWS-built coastal homes regularly, and that means we’ve learned which cabinet lines, hardware, and window packages actually hold up to Montara’s marine conditions – and which ones turn to rust and mush within a few seasons. Contractors handling CWS in El Granada don’t get that education because inland CWS installs don’t fail the same way. We’re independent, so when a factory fastener or seal is the weak link, we swap it for marine-grade stainless and proper weatherseal without having to ask a manufacturer’s permission. That’s the point of hiring someone who isn’t tied to CWS: you get a straight answer about what needs replacing versus what’s still got life in it.
Glen Sorrento, our owner, grew up in Foster City watching lagoon-side homes get framed, rebuilt, and re-finished over the years. That led to building construction technology at College of San Mateo and two-plus decades working across nearly every Peninsula project type. When a Montara homeowner asks whether a CWS sliding door can be saved or should be pulled, Glen’s seen enough salt-corroded track assemblies to give an answer without flinching. Let’s figure out what the job actually needs – then we’ll talk materials.
Styles & brands we work with







Common CWS Construction Problems We Solve in Montara
- Corroded steel fasteners at window frames and jambs. CWS aluminum windows often install with carbon-steel screws that sit right in the path of Montara’s ocean-driven moisture. We see these stain, swell, and seize on ocean-facing walls much faster than anything a spec sheet would predict. We replace them with marine-grade stainless and re-bed the frame properly.
- Fogged IGU double-panes on west-facing windows. Salt spray and wind-driven sand abrade glazing seals, and once the argon leaks out, you get condensation between the panes. We keep replacement IGU units on hand and re-glaze with seals spec’d for coastal exposure rather than standard inland rubber.
- Vinyl frame tracking and sandy-grit buildup in CWS sliders and single-hungs. Blowing sand off Montara’s dunes works its way into tracks and weeps, making sashes grind, stick, or refuse to open. Cleaning a track helps for a week; replacing worn balances and clearing clogged weep holes so water actually drains is what lasts.
- Failed perimeter caulk and flashing at window and door openings. Wind-driven rain and fog push moisture behind CWS products when the original sealant shrinks or peels. In Montara, this isn’t cosmetic – water in wall cavities leads to rot, mildew, and costly structural repairs if left alone.
- Sliding glass patio doors that seize or bind. Between salt corrosion on rollers and sand packed into bottom tracks, CWS patio doors on dune-adjacent lots often stop gliding entirely. We rebuild rollers, replace tracks, and when the frame’s reached its limit, we say so plainly – patching a corroded unit is throwing money at salt damage.
CWS Service in Montara: What Local Conditions Mean for Your Equipment
One factor separates Montara from every other Peninsula city we work in, and it’s not just the fog. It’s the blowing sand. On the west-facing side of town, off the dunes and bluffs, wind-driven sand literally sandblasts paint, sealant, and window glazing, which is why a CWS unit on an ocean-facing wall in Montara can look ten years older than the identical model installed three miles inland. Contractors who don’t work Montara don’t account for this because they’ve never watched a vinyl window track fill with fine grit in a single windy season. We have. Up on the bluff side of Montara, we replaced a row of fogged, sand-pitted CWS aluminum sliders for a beach cottage whose frames had corroded so badly the tracks seized. We reset new units with stainless fasteners, marine-grade flashing, and sealant, and the homeowners can finally open the slider without a pry bar. Any CWS window or door we install in Montara gets marine-grade caulk and stainless fasteners with a shorter re-seal cycle than the same opening in, say, San Bruno or South San Francisco. That’s not a premium upsell – it’s the only spec that survives here.
CWS Models & Products We Service in Montara
We work on CWS 100 Series aluminum single-hung and sliding windows, CWS 200 Series vinyl replacement windows, CWS sliding glass patio doors, and CWS vinyl-framed bay and picture windows. Our parts approach is straightforward: we stock OEM CWS sash balances, glazing gaskets, and replacement IGU units so repairs go quickly, and we won’t install a factory carbon-steel fastener where a marine-grade stainless one belongs. If you’ve got a CWS product we didn’t list and you’re not sure whether it’s serviceable, call us with the model number – we’ll tell you straight whether it’s worth repairing or replacing.

FAQs – CWS Construction in Montara
No. Seaside Contractors is an independent general contractor, not a CWS dealer, not an authorized warranty provider. That independence is the point. We spec the right materials for Montara’s conditions instead of whatever the manufacturer’s standard callout says, and we swap factory weak points like carbon-steel fasteners for marine-grade stainless without needing approval.
Yes, wherever the factory part is still the right part. We stock OEM CWS sash balances, glazing gaskets, and replacement IGU units. But when a CWS hardware spec is failing in salt air – plated screws, flimsy weatherseal, weep designs that clog with sand – we use a better part instead and tell you why.
Most repairs finish in one visit, especially when we have the right IGU or balance in stock. Full window replacement or a garage conversion runs weeks, sometimes months depending on permit timing, structural work, and weather windows. Coastal wind and fog can push exterior work up or down a few days.
Yes, and in a specific way. When we convert a Montara garage into living space, we remove the big CWS garage door and reframe the opening for windows or French doors. That new opening sits exactly where standing water meets wind-driven salt, so flashing, fasteners, and the sill pan all need to be marine-grade – not the standard detail you’d use on an interior remodel in Walnut Creek. We pull permits, set the envelope correctly, and the result is a wall that doesn’t leak in the first coastal winter.
For most Montara homes, CWS window replacement runs $4,500 to $15,000 depending on how many openings and whether they’re ocean-facing. If you want impact-rated, $8,000 to $25,000 is the typical range. Call (833) 589-8103 for an exact quote – estimates are free.
