CWS Construction in Montclair, CA | Timberline Contractors
We’re Timberline Contractors, our General Contractor in Montclair, an independent team that installs and services CWS cabinetry, countertops, and finish products throughout the area. The short version: most CWS work here lands in 1950s – 70s tract homes with original out-of-plumb framing, so we spend as much time correcting substrate as we do setting boxes. Nelson Fung and our crew have been making CWS plywood-box cabinets fit square in houses that were never square for years, and we’d rather show you what that means than tell you. Call us at (866) 253-5808 for a free estimate on your Montclair project.
Why Montclair Residents Choose Us for CWS Service
We’re not a CWS dealer or factory rep. We’re the crew that has to make the boxes plumb, the reveals line up, and the quartz sit flat on walls that have spent sixty years settling on Pomona Valley clay. CWS sales & service is one thing from a showroom; it’s another thing inside a galley kitchen off Holt Boulevard where the rear wall bows nearly an inch out of plumb. That’s the work we know. Nelson grew up in Chinatown, Los Angeles, where his grandfather debated tile prices at Saigon Plaza hardware stalls every Saturday morning, and he learned the trade formally at Los Angeles Trade-Technical College before spending years swinging hammers on everything from Eastside bungalows to mid-size commercial builds. The habit of caring about substrate before finish comes from that. For Montclair homeowners, that means we don’t just swap cabinets; we correct the framing, shim the runs, and set the countertop to the corrected wall.

Common CWS Construction Problems We Solve in Montclair
- Cabinet boxes jacked out of square against out-of-plumb 1950s – 70s framing. Montclair tract homes settled on expansive clay soil, and we regularly find rear kitchen walls that have drifted an inch or more off vertical. Doors rub, reveal lines wander, and the run looks wrong from every angle. We sister and shim framing true before anything gets set.
- Quartz or granite slabs cracked at the sink cutout. In narrow galley kitchens and partial remodels, a run of base cabinets sometimes gets removed without accounting for what that does to the unsupported span. CWS slabs need continuous bearing. We check every span before we template, because a cracked slab is a $2,000 – $6,500 redo in Montclair’s price range.
- Drawer glides and hinges failing early on west-facing kitchens. Hot Pomona Valley afternoon sun pours through original single-pane windows, and cabinet faces dry out, swell, and stress hardware. We source genuine OEM CWS glides and hinges instead of bargain-bin replacements that fail in two summers.
- Water damage and delamination at sink bases and toe kicks. Homes with original galvanized supply lines develop slow under-sink leaks that eat the cabinet box before anyone notices. We repair the damaged plywood and address the supply line as part of the same job.
- Floating and connected island systems racked out of level. Tight Montclair lots mean rear-yard additions and kitchen islands go into spaces that were never meant for them, often against existing block-wall property lines with no room for error. The island has to be level against a floor that isn’t.
CWS Service in Montclair: What Local Conditions Mean for Your Equipment
Montclair is fully built out, so almost every CWS kitchen or bath we install goes into a 1950s – 70s single-story tract home on a tight lot near the 10 freeway, not new construction — though we also handle CWS service in Ontario for similar homes. That changes the job from day one. Fresh framing accepts a cabinet run with minor shimming; Montclair framing has settled on the valley’s expansive clay soil for six or seven decades, and the rear wall of a galley kitchen can be a full inch out of plumb. On a postwar tract bungalow off the Holt Boulevard corridor, our crew pulled a dated CWS cabinet run from a galley kitchen and found the rear wall bowed nearly an inch out from decades of clay-soil settlement. We sistered and shimmed the framing true before setting new CWS plywood-box uppers and bases, then scribed a quartz countertop to the corrected wall and re-hung the doors so every reveal lined up, no rubbing, no gaps at the ceiling line. That’s the difference between a CWS install in a new-build subdivision and CWS work in Montclair, and it’s why we don’t skip the framing step. Nelson’s phrase for it: do it right the first time or explain yourself twice.
CWS Models & Products We Service in Montclair
We work with CWS semi-custom plywood-box kitchen cabinetry with dovetail drawer construction, CWS quartz and granite countertop slabs including value-tier program slabs, CWS vanity and bath cabinetry lines, and CWS floating and connected kitchen island cabinet systems. Our parts approach is simple: genuine OEM CWS hinges, glides, and touch-up materials whenever they’re still available, and quality aftermarket hardware only when an OEM part has been discontinued. We keep common CWS hardware and touch-up stock on hand for faster turnaround across Montclair service area jobs, so a hinge or glide replacement doesn’t stall your kitchen for a week. On any given cabinet run, we’ll tell you straight whether re-facing and re-hardware is the right spend or whether the boxes themselves are too far gone to justify it.

AfterCWS Service Pricing in Montclair
CWS work here spans a wide band because the condition of the underlying framing dictates how much prep the job needs. A straight cabinet swap in a kitchen with mostly plumb walls costs far less than the same cabinet run in a settled 1950s tract home that needs framing correction first. Here’s where typical Montclair projects land:
| CWS Service | Typical Montclair Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Cabinet Installation | $4,000 – $13,000 |
| Countertop Installation | $2,000 – $6,500 |
| Bathroom Remodel | $9,000 – $28,000 |
Every estimate is free and written as a line-item quote before we start. You’ll see labor, materials, and any framing correction as separate lines, so there’s no mystery about what the wall that isn’t square is costing you. Call (866) 253-5808 to schedule yours.

FAQs – CWS Construction in Montclair
Yes, and that’s most of what we do in Montclair. We sister and shim original framing back to plumb before setting any CWS boxes, so doors line up and reveals stay consistent. The cabinets go on straight; the wall gets corrected first. Call (866) 253-5808 and we’ll take a look at what you’ve got.
No. We’re an independent general contractor, not a CWS dealer and not manufacturer-affiliated. We work with CWS products because Montclair homeowners ask for them, and we know their cabinet boxes and countertop slabs well. That independence means we install what’s right for your house, not what moves inventory.
Usually yes. Montclair galley kitchens are narrow by design, and that’s exactly where good plywood boxes, full-height uppers, and a properly supported slab make the biggest difference in usable space and daily function. We’ve done full CWS remodels in kitchens under 100 square feet. Call (866) 253-5808 for a free estimate.
Almost always an unsupported span. If a run of base cabinets was removed during a previous partial remodel, or if the slab overhangs a dishwasher opening without proper support, the sink cutout becomes a stress point and the quartz cracks. We check bearing and span before we template, and we won’t set a slab that doesn’t have full support.
Often, yes. If the boxes are structurally sound, square, and free of water damage, refacing with new doors, drawer fronts, and hardware is a fraction of the cost of new cabinets. We’ll tell you honestly when refacing is the right spend and when the boxes are too far gone to justify it. Call (866) 253-5808 to schedule an assessment.
