CWS Construction in Highland, CA | Square One Builders
We provide independent CWS in San Bernardino service and installation across Highland, from walk-in shower conversions to roof repair on the wildland-urban interface properties that line the foothills. We’re a full-scope general contractor who works with CWS products every week, and we’re not manufacturer-affiliated or authorized. What makes our CWS work different here: we understand how Highland’s Cajon Pass wind-driven ember exposure and San Bernardino County fire-defensible construction requirements change the way a shower pan gets set or a roof-to-wall transition gets flashed. Call (877) 688-9930 for a free estimate.
Why Highland Residents Choose Us for CWS Service
Most CWS repair in Muscoy and Highland starts with a homeowner who’s tired of juggling a plumber for the valve, a tile guy for the surround, and a roofer for the flashing. That’s the problem we solve by being one contractor with one accountable team. Brent Calloway, our owner and general contractor, has spent the better part of three decades on residential projects throughout Southern California, and he’s built Square One Builders around the idea that a remodel should be scoped, planned, and executed from the ground up with nobody pointing fingers when something goes sideways.
We spec genuine OEM cartridges, trim, and receptor components for CWS systems where they exist. When OEM supply is thin or a part is a known weak point, we say so and spec a quality aftermarket alternative. Highland homeowners don’t need a lecture about brand loyalty; they need straight answers about what will actually hold up through hot summers, Santa Ana winds, and the occasional intense winter rain. Start from square one, build it right.

Common CWS Construction Problems We Solve in Highland
- Cracked acrylic receptor pans: Highland’s mid-century ranch homes often sit on slabs that settled decades ago. A CWS shower pan set on an out-of-level or flexible subfloor flexes with every step, and hairline cracks follow. We see flex-pump leaks in these pans more than any other single failure.
- Seized or scored valve cartridges: Hard Inland Empire water loads valve and trim cartridges with mineral scale. The result is a drip that won’t quit or a temperature control that drifts between scalding and cold without warning. We replace cartridges with OEM where possible or spec a better-built aftermarket valve when the original is a known problem.
- Split surround sealant joints: Caulk at CWS surround seams dries out and splits fast through Highland’s hot, dry summers and fall wind events. Once that seal opens, moisture gets behind the wall and you don’t know until the studs tell you. We use flexible, fire- and heat-rated sealants suited to this climate, not whatever is on the shelf at the nearest big-box store.
- Roof-to-wall flashing failures: Wind-driven Santa Ana rain pushes water where flatland installs never expect it: up and under roof-to-wall transitions. CWS flashing and drainage accessories installed to standard tract-home detailing fail here. We re-flash for Highland’s actual wind direction and rainfall intensity.
- Drain assembly leaks at the receptor: The rubber gaskets and compression fittings on older CWS drains dry out and crack through repeated heat cycling. We replace the entire drain assembly rather than slopping sealant on a tired gasket and hoping it holds.
CWS Service in Highland: What Local Conditions Mean for Your Equipment
Highland sits near CWS in Redlands at the base of the San Bernardino Mountains where the Santa Ana winds funnel through the Cajon Pass corridor. That’s not a weather footnote; it’s an engineering directive. Every piece of exterior work we do here, and a fair amount of interior work, has to answer for wind-driven ember exposure and wildfire defensibility. For CWS specifically, that means roof repair and flashing work on Highland homes is scoped around ember-resistant vents, Class A roof assemblies, and San Bernardino County fire-defensible construction requirements rather than standard tract-home detailing. A shower remodel rarely triggers those codes directly, but the roof-to-wall transition above the bathroom absolutely does. We’ve seen hillside properties along the city’s northern boundary where a poorly flashed roof edge leaked into the wall cavity behind a brand-new shower surround within two winters. The two systems look separate on paper; they’re not in practice. Our team coordinates both so the work actually holds.
CWS Models & Products We Service in Highland
We work on the full range of CWS product lines you’ll find in Highland homes. That includes CWS prefabricated shower and tub-surround systems, CWS acrylic walk-in shower bases and receptor pans, CWS shower valve, trim, and drain assemblies, and CWS roofing underlayment and flashing accessories. For shower work, we carry common OEM cartridge and trim sets stocked locally so a valve rebuild doesn’t sit waiting on a backorder. On older CWS surrounds, we tell owners honestly when rebuilding a pan and valve makes sense versus when full replacement is the cheaper long-term call. The answer usually comes down to the condition of the subfloor and whether the pan has already started cracking. We’ve learned not to rebuild a shower on a slab that needs work first.

AfterCWS Service Pricing in Highland
Pricing on CWS-related work in Highland depends on the condition of what’s already there, the size of the shower or roof area, and what we find when we open it up. Here are the ranges we typically see:

| Shower Replacement | $3,000 – $8,500 |
| Bathroom Vanity Installation | $800 – $3,000 |
| Roof Repair | $400 – $1,800 |
What drives the cost in Highland is usually subfloor leveling, fire-defensible detailing on adjacent roof work, and whether the valve and drain need full replacement rather than a cartridge swap. Our free estimate includes a written line-item quote so you know exactly what you’re paying before we start. Call (877) 688-9930 to schedule one.

FAQs – CWS Construction in Highland
Yes, if the surround walls are in good shape and the subfloor can be leveled without disturbing them. We remove the old pan, correct the slab or subfloor, set a new CWS acrylic receptor, and re-seal the wall-to-pan joints. If the walls are cracked or the framing behind them has moisture damage, we’ll tell you a full replacement is the more honest call. Call (877) 688-9930 and we’ll assess your shower before recommending anything.
Not the interior shower work itself, but it frequently affects the roof and exterior wall work above or adjacent to the bathroom. If we’re converting a tub to a shower on a wall that shares a roof-to-wall transition, San Bernardino County fire-defensible standards may require ember-resistant venting or upgraded flashing as part of the project. We scope that from the start so your permit doesn’t stall mid-job.
That’s a scored or seized cartridge, almost always the result of hard water mineral buildup in Highland’s supply lines. We try an OEM cartridge and trim rebuild first, which typically runs a few hundred dollars. If the valve body itself is corroded or the trim is shot, replacement is the better call. The decision depends on what we find when we pull the cover plate. Call (877) 688-9930 and we’ll give you a straight answer and a written quote.
Highland’s hot, dry summers followed by Santa Ana wind events cause standard silicone caulk to shrink and crack within a season or two. We use flexible, fire- and heat-rated sealant that moves with the seasonal expansion without opening up seams. If it’s already split repeatedly, there may also be movement in the wall framing or subfloor that needs correcting first. Call (877) 688-9930 for an inspection.
Yes, and that’s exactly why homeowners call us instead of coordinating a plumber, a tile contractor, and a roofer separately. We schedule the work so the bathroom remodel and the roof-to-wall flashing above it are done by one accountable team under one contract. Call (877) 688-9930 for a free estimate on the full scope.
