KraftMaid Home Additions & ADU Nationwide

KraftMaid Home Additions & ADU: The Rancho Cucamonga Owner’s Guide

We stock and install KraftMaid-compatible cabinetry and storage systems for home additions and ADUs in Rancho Cucamonga, with typical installed project pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for detached ADUs. Most KraftMaid cabinet orders for our Rancho Cucamonga projects arrive within 4-6 weeks, and we coordinate delivery to align with your framing and rough-in schedule so nothing sits in the garage warping in the Inland Empire heat. Homeowners usually discover a problem when drawer boxes start binding, door hinges sag on cabinets installed in converted garage spaces, or the original builder-grade storage can’t accommodate the deeper footprint of a modern ADU kitchen.

Which KraftMaid Models This Applies To

KraftMaid’s product lines break into three tiers that matter for additions and ADUs in Rancho Cucamonga: the standard Vantage series, the upgraded Canvas line with soft-close standard, and the full-custom Passport collection with 3/4-inch plywood box construction. The label inside your cabinet door or drawer box shows a six-digit SKU starting with the series code - V for Vantage, C for Canvas, P for Passport - followed by dimensions and finish codes. For ADU kitchens, we typically spec Canvas or Passport because the 1/2-inch particleboard core in Vantage doesn’t handle the temperature swings of a converted garage or standalone unit as well as plywood.

The OEM-versus-aftermarket decision for KraftMaid is straightforward on boxes and doors, less so on hardware. We order KraftMaid factory boxes and fronts through our distributor so colors match across a phased project, but we source Blum Tandem drawer slides and Grass or Salice hinges independently - same performance, faster availability, and we can stock them on our truck rather than waiting on a factory parts shipment. If you’re trying to match existing KraftMaid cabinetry in a main-house kitchen to a new ADU, bring us a door sample; the finish codes change every few years and “Canvas White” from 2019 is not the same white as 2024.

Signs Your KraftMaid Home Additions & ADU Is Failing

• Drawer boxes stick or slam. The original nylon roller slides have worn flat spots, or the particleboard drawer sides have swelled from humidity in a space without proper HVAC. In Rancho Cucamonga, we see this most in garage conversions where the mini-split wasn’t sized for the thermal load.
• Doors hang crooked or won’t close flush. Hinge cups have wallowed out in particleboard frames, or the three-way adjustment has maxed out and can’t compensate for frame settling. This is common in additions built on post-tension slabs that shift slightly in the first two years.
• Shelves bow or clips pull through. The 1/2-inch shelf stock is overloaded with small appliances, or the plastic shelf pins have crystallized in dry heat. We upgrade to metal pins and 3/4-inch plywood shelves on replacement.
• Finish peels at sink and cooktop cabinets. Thermofoil delaminates from steam and grease; painted MDF cracks at joint lines. Rancho Cucamonga’s hard water and summer humidity accelerate both failures.
• Base cabinets rock or separate from walls. The toe-kick has compressed into an unlevel floor, or the installer used drywall screws instead of cabinet screws into studs. We find this in about one in five ADU conversions we open up.

Replacement Cost & What’s Included

What drives the range: box material (particleboard versus plywood), door style complexity (slab versus raised panel versus inset), finish type (thermofoil, painted, stained), and whether we’re matching existing or starting fresh. Under Clause 1 of The Haven Standard, every price is written before work starts - no allowances, no “we’ll figure it out in the field.” Our 365-Day Done Right Promise covers the installation and hardware; KraftMaid’s limited lifetime warranty covers the cabinet box and door construction itself.

DIY or Call Us?

There’s a clear line between what an owner can check and where a project goes sideways. You can verify that a door is hitting the frame because a hinge screw has backed out - tighten it with a #2 Phillips and see if the adjustment range returns. You can measure your cabinet opening and compare it to KraftMaid’s published specs, which are accurate to 1/16 inch.

Where DIY goes wrong: ordering replacement doors without accounting for the hinge bore pattern (KraftMaid uses a 35mm cup at 3mm depth, but boring distance from door edge varies by series), or attempting to level base cabinets on a slab that needs grinding first. The worst calls we get are from homeowners who removed a bank of cabinets to find mold behind, then discovered their homeowner’s policy has a $5,000 mold cap. If you’re past the “tighten a screw” stage, call (909) 373-9612. We’ll photo-document what we find, write the scope, and give you a price before anything comes off the wall.
