CWS Construction in San Bernardino, CA | Hampton Contractors
We’re Hampton Contractors, an independent CWS service in Muscoy and across San Bernardino. We handle CWS window and patio door repairs, replacements, and installation for the 92401 through 92404 ZIP codes. What sets our CWS work here apart is simple: we evaluate every opening against the Santa Ana wind loading that comes through the Cajon Pass, because windows that survive in Redlands don’t always hold up on the west side. Call (833) 467-4075 for a free estimate on CWS repair or replacement.
Why San Bernardino Residents Choose Us for CWS Service
Most contractors can swap a window. Few understand why CWS aluminum sliders seize up faster on 92404 tract homes than they do two miles south. Brent Calloway, our owner, grew up off Ranchero Road in Hesperia and has been working construction in the High Desert since he was eighteen. He learned framing and finish carpentry at Victor Valley College, and two-plus decades of site work taught him the rest. Our crew has pulled CWS units out of stucco openings all over San Bernardino, and we know which failures are repairable and which call for CWS in Highland or a full replacement. We carry OEM hardware when we can get it, and we know which aftermarket balances and locks actually hold up to the grit that blows through the pass. When you call us, you get a straight answer about what your windows need. Good work doesn’t need a disclaimer.

Common CWS Construction Problems We Solve in San Bernardino
- Seized aluminum slider tracks. Grit from dry-season wind events gets into the track, pits the aluminum, and eventually the window won’t move. We see this constantly on west-side and central tract homes where original CWS aluminum sliders are still in service.
- Fogged dual-pane glass. Seal failure comes from pressure cycling during Santa Ana events and heat expansion on south- and west-facing exposures. A fogged unit on a San Bernardino home is usually a wind-and-sun failure, not a manufacturing defect.
- Water intrusion at the head and sill. Older stucco openings were often installed without proper pan flashing. Wind-driven rain through the Cajon Pass finds those gaps fast. We rebuild the flashing and seal the opening correctly.
- Vinyl frame cracking and failed locks. Hot, dry summers bake south-facing vinyl. We’ve seen frames crack along the corners and locks snap under wind load. Broken locks on a wind-rated opening are a security issue and a weather-exposure issue.
- Whistling windows under wind pressure. A slider that whistles during a Santa Ana event is telling you the weatherstripping is shot and the sash isn’t seating. We replace seals and adjust or replace rollers to stop the noise and the draft.
CWS Service in San Bernardino: What Local Conditions Mean for Your Equipment
Here’s the thing about San Bernardino that doesn’t apply the same way in Ontario or Rancho Cucamonga: the Cajon Pass funnels high Santa Ana winds directly into the city, and much of the west-side and central tract housing still runs original single-pane aluminum CWS windows that were never rated for that sustained pressure. On homes along the 92404 and 92405 corridor, we regularly see windows that flex visibly during wind events, pulling sashes away from frames and blowing seals. A window that survives twenty calm years can lose its glass seal in one strong wind season. That’s why we treat every CWS service call here as a wind-load question first. Glass condition, lock function, flashing integrity, and weatherstripping all get evaluated against what the Cajon Pass actually delivers. Homeowners near the foothill interface have a second layer to consider: wildfire-interface codes push toward tempered or fire-resistant glazing in certain zones. We navigate both issues on almost every job we touch in the 92401 and 92404 hillside areas.
CWS Models & Products We Service in San Bernardino
We work on the full range of CWS windows and patio doors common to San Bernardino’s post-WWII stock: aluminum single-hung and slider windows, vinyl single-hung replacements, sliding glass patio doors, and vinyl horizontal sliders. When OEM hardware and glass are available, we source them. When CWS has discontinued a part, we move to quality aftermarket balances, locks, and weatherstripping that match the original spec. Our stance is straightforward: if the frame is sound and only seals or hardware failed, we repair. If an aluminum unit is pitted, seized, or leaking at the opening, replacement is the honest call. We carry common CWS-compatible parts in our truck stock for fast San Bernardino turnaround. For more on our CWS background, see our CWS sales & service page.

FAQs – CWS Construction in San Bernardino
Yes, in most cases we can replace the insulated glass unit alone if the frame and sash are still sound. The exception is old aluminum frames that are pitted or out of square after years of wind loading. We’ll tell you which path you’re on after we pull the sash and inspect it. Call (833) 467-4075 for an evaluation.
Usually, yes. Once aluminum tracks are pitted from years of dry-season grit, cleaning and lubrication won’t bring them back. Repair only makes sense if the track is intact and the rollers are the issue. On west-side tract homes with original single-pane units, replacement with wind-rated vinyl sliders is normally the better investment. Call (833) 467-4075 and we’ll inspect yours and give you a straight answer.
It depends on the specific zone. Some homes along the wildland-urban interface in the 92401 and 92404 foothills fall under fire-hardening codes that call for tempered or dual-pane glazing, and certain openings may require specific glass. We check current San Bernardino requirements for your property before recommending products.
For wind, look at impact-rated or heavy-duty vinyl frames with reinforced sashes and quality weatherstripping. For heat, low-E dual-pane glass cuts solar gain on south- and west-facing openings. The mix depends on your exposure and whether you’re in a fire-interface zone. We’ll spec options that balance both without overselling you glass you don’t need.
Yes. We pull the old unit, rebuild the sill pan and head flashing, set the new window, seal the opening, and patch the stucco to match. We’ve done enough of these on San Bernardino tract homes that the stucco work blends in.

Out on the west side near the older 92405 tract blocks, our crew took a call after a strong Santa Ana event where a homeowner’s CWS aluminum sliders were seized and whistling, with a dual-pane unit fogged at the southwest exposure. We replaced the two sliders with wind-rated vinyl units, rebuilt the sill pan and flashing, and sealed the stucco openings. No more whistle, and the windows open and lock cleanly through the next wind season. That’s the kind of fix we do, from CWS repair in Loma Linda to across San Bernardino. If your CWS windows or patio doors are fighting you, call (833) 467-4075 for a free estimate. We’re independent, not manufacturer-affiliated, and we’ll tell you plainly what needs replacing and what doesn’t.
