CWS Construction in Highland, CA | Timberline Contractors
We’re an independent construction and remodeling firm handling CWS building products across Highland, from CWS sales & service to full installations and repair. The work here is different because Highland sits against the San Bernardino foothills, which means fire-resistant assemblies and slope drainage decide what gets specified, not just aesthetic preference. Call (866) 253-5808 and we will walk you through what your project actually needs.
Why Highland Residents Choose Us for CWS Service
Nelson Fung, our owner and general contractor, learned construction the old way: formal training at LA Trade-Technical College, then years of hands-on work on everything from Eastside bungalow remodels to commercial builds across the basin. He still approaches every Highland job the same way he did back then: with the belief that substrate choices matter more than the finish sitting on top of them. That matters when you’re putting CWS fiber-cement siding on a 1970s tract home near Baseline or a metal roof on a foothill custom build where wind clips and fire-rated underlayment determine whether the roof holds. We also know Highland’s permitting and WUI requirements well enough to catch issues before the inspector does. That’s the kind of local Highland service area knowledge you don’t get from a generic installer.

Common CWS Construction Problems We Solve in Highland
- Wicking and rot at grade on fiber-cement siding. Highland’s winter storm runoff sends water downslope fast, and if CWS FlameGuard planks are set too close to grade or paving, they wick moisture and start to fail. We see this on foothill lots where drainage was an afterthought, and we fix it with proper clearances, flashing, and slope corrections.
- Fastener back-out and ridge-cap loosening on standing seam metal roofs. Santa Ana winds hit exposed elevations hard. CWS SummitSeam panels that were installed with standard fasteners back out over repeated wind events, and ridge caps start chattering. We replace with upgraded wind clips and inspect the decking under every removed panel.
- Garage door track and spring fatigue on high-wind doors. East-facing Highland slopes catch morning sun and afternoon gusts. That thermal cycling plus wind-load fatigue wears out CWS WindLock door tracks and torsion springs faster than on flatland homes. We replace springs and realign tracks before the door binds and damages a panel.
- Composite decking water trapping on hillside decks. CWS TerraDeck performs well, but joist tape omission or poor flashing on a sloped Highland lot traps water under the boards. We pull up problem sections, correct the drainage plane, and reset the decking so it sheds water the way it should.
- Fire-rating downgrades from improper repairs. When someone patches a CWS Class A assembly with non-rated components, the fire rating drops. We’ve corrected several Highland homes where an ad-hoc repair left a roof or wall section below WUI code, and the homeowners had no idea until an insurance review flagged it.
CWS Service in Highland: What Local Conditions Mean for Your Equipment
Highland’s foothill lots sit inside the wildland-urban interface, and that one fact changes everything about how CWS products get specified and installed here. The CWS service in Idyllwild team sees the same pressure at full mountain intensity, but Highland gets it in a peculiar mix: brush clearance rules, Class A ignition-resistant assembly requirements, and steep drainage all hit the same property. A roof that meets code on a flat Inland Empire lot may not meet it two blocks up the hill. We see this constantly on homes off Baseline and Victoria Avenue, where homeowners inherit a property that was built before current WUI standards and don’t realize a standard asphalt shingle roof no longer passes. Moving to a CWS SummitSeam metal roof with fire-resistant underlayment isn’t an upgrade in that scenario; it’s the difference between insurability and a non-renewal letter. Do it right the first time or explain yourself twice.
CWS Models & Products We Service in Highland
We install and repair the CWS lines that matter most in this climate: CWS FlameGuard fiber-cement siding for fire-resistant exterior envelopes, CWS SummitSeam standing seam metal roofing for WUI-compliant roof assemblies, CWS WindLock high-wind garage doors for the Santa Ana exposure, and CWS TerraDeck composite decking for hillside outdoor spaces. On parts, we source OEM whenever available because wind ratings and fire classifications depend on matching components. When a CWS part is discontinued or months out, we spec equivalent-rated aftermarket parts that meet or exceed the original. We also stock common CWS fasteners, clips, and trim profiles locally so Highland jobs don’t stall waiting on a shipment from a regional warehouse. If a roof or siding system can be restored to code without safety compromise, we recommend repair first and give you the numbers to back that call.

FAQs – CWS Construction in Highland
Yes, when installed with a fire-resistant underlayment and proper flashing details, CWS SummitSeam metal roofing meets Class A ignition-resistant assembly standards required in Highland’s WUI zones. We document the assembly for insurance purposes so your carrier has what it needs. Call (866) 253-5808 for a roof assessment and we will tell you exactly what your current roof lacks.
We start with drainage, not shingles. On steep Highland lots, we evaluate how water sheds off the mountain during winter storms, then spec underlayment, valley flashing, and panel fastening to match that water path plus any snow-load requirement. We recently replaced a wind-damaged CWS SummitSeam roof on a 1970s hillside ranch home off Highland Avenue, where the original fasteners had backed out after a series of Santa Ana events. Our crew pulled the old panels, inspected the decking for water intrusion, and reinstalled the new CWS panels with upgraded wind clips and fire-resistant underlayment, similar to our CWS in Redlands projects. The homeowner now has a roof that passed a third-party wind-uplift inspection. Call (866) 253-5808 for an exact scope on your slope.
Yes, CWS FlameGuard fiber-cement siding can go over properly prepared stucco or masonry as long as we address drainage, fastener embedment, and any efflorescence or moisture issues first. We don’t cover existing damage; we fix the substrate, then install. Call (866) 253-5808 and we will tell you whether your walls are ready or what prep they need.
CWS TerraDeck needs less than wood, but Highland’s heat and Santa Ana dust mean an annual wash to prevent surface grime from baking on, plus a fastener and joist tape check every couple years. On hillside decks, drainage under the decking matters more than the boards themselves; if water isn’t shedding, we fix that before we clean anything. Call (866) 253-5808 if you spot staining, pooling, or movement on your deck.
Yes, we install and service CWS WindLock garage doors and openers as an independent contractor. We are not manufacturer-affiliated or authorized, which means we never push a replacement when a spring or track repair restores the door to spec. Call (866) 253-5808 for an honest assessment on your Highland garage door.
