24 February, 2026Site Readiness Checklist: Before Your Cabinets Arrive
Introduction
Why Site Readiness Matters
Preparing your space before your custom cabinets arrive is one of the most important steps in ensuring a smooth installation. For homeowners on Vancouver Island, especially in older homes in Nanaimo, Lantzville, Qualicum, or Duncan, site conditions can vary dramatically. Proper readiness helps your cabinet installer work efficiently, protects your investment in custom millwork, and minimizes the chance of delays. Whether you’re receiving fully assembled custom cabinetry or flat-pack/RTA components for on-site assembly, having a clear, clean, and accessible environment helps ensure that your new kitchen, bathroom vanity, or closet system fits exactly as planned.
Overview of the Cabinet Installation Process
The installation of custom cabinets typically begins long before the installer arrives at your home. It starts with detailed site measurements, digital layouts, and 3D design work. Once cabinetry is engineered—often using 5/8-inch plywood cabinet boxes, soft-close hardware, and shaker or slab doors—the build process begins. After assembly, your cabinets are inspected, packaged, and scheduled for delivery. On installation day, your crew will level bases, secure cabinet boxes, check appliance openings, and prepare for countertops, such as quartz templates. A well-prepared site ensures each of these steps can occur without interruption.

Preparing Your Space
Clearing the Installation Area
Before your custom cabinets arrive, the installation area must be completely clear. This is especially important in kitchens and bathrooms where tight spaces can limit the installer’s ability to move tools, materials, and assembled plywood cabinet boxes.
Key tasks include:
- Removing all personal items, décor, and small appliances.
- Ensuring old cabinetry and countertops have been removed unless included in your service.
- Clearing adjacent spaces to accommodate tool setup and components.
- Protecting nearby flooring with temporary coverings.
A clutter-free workspace allows for precise layout checks, clean scribing lines, and efficient installation of base and wall cabinets.
Verifying Measurements and Layout
Even when measurements were originally taken by professionals, it’s important to verify that nothing has changed during renovation. A new wall, a slight shift in drywall, or a modification to a plumbing line can affect cabinetry alignment. For example, a panel-ready fridge requires precise spacing, and a bathroom vanity cabinet with an undermount sink needs accurate plumbing rough-ins.
Homeowners should check:
- Wall lengths match the approved design.
- Rough plumbing locations are consistent with the vanity or sink base cabinet layout.
- Electrical rough-ins match locations of appliance panels, under-cabinet lighting, or microwave cabinets.
- Flooring thickness is finalized to avoid changes in cabinet height or appliance clearances.
Ensuring Proper Lighting and Access
Good lighting is essential for installers to verify levels, adjust soft-close hinges, and ensure consistent reveals along doors and drawers. If your renovation includes electrical work, ensure temporary lighting is available. Also, installers need a clear path from the delivery truck to your home’s interior.
Plan for:
- Clear walkways free of renovation debris.
- Temporary task lighting if fixtures are not yet installed.
- Easy access to parking for safe unloading of cabinetry.
- Unlocked entry points during the entire installation window.
Structural Requirements
Wall and Floor Condition Checks
Cabinets need stable, structurally sound surfaces. Uneven floors or bowed walls may require shimming or scribing to ensure clean alignment. Custom plywood cabinet boxes are designed to be square, so the floors and walls must be ready to receive them.
Before delivery, confirm:
- Drywall is patched, primed, and dry.
- Flooring is installed or, if not, that height adjustments have been discussed.
- No major dips or humps are present in the subfloor.
- Wall studs are exposed where required for specialty anchors or heavy quartz countertop loads.
Electrical and Plumbing Pre-Inspections
Installing custom kitchen cabinets or a bathroom vanity requires coordination with trades. Electrical and plumbing rough-ins must be fully complete and inspected before cabinets arrive. Delays in these areas can prevent base cabinets from being anchored or can interfere with sink base cabinetry.
Confirm that:
- Plumbing for sinks, dishwashers, and fridge water lines is correctly positioned.
- Electrical outlets meet the layout for appliances, lighting, and code requirements.
- HVAC vents do not conflict with cabinet toe kicks.
- Wall blocking is installed where heavy floating vanities or shelving will mount.

Scheduling and Communication
Confirming Delivery Dates
Cabinet delivery schedules can shift depending on build volume, finishing time, and transportation logistics. Approximately one week before installation, confirm your delivery window. This ensures you can prepare your site and coordinate with other trades such as countertop installers or flooring crews.
Coordinating With Builders and Designers
If you’re working with a general contractor or interior designer, everyone should be aligned on the schedule. Installers must know when flooring, drywall, electrical, and plumbing will be ready. Likewise, countertop teams need to be scheduled after base cabinets are secured—typically within a few days to a week, depending on availability.
Post-Delivery Considerations
Storage and Handling of Cabinets
If you need to store cabinets before installation, ensure they are placed in a dry area. Moisture can affect natural wood doors, drawer fronts, and plywood components. Avoid stacking heavy items on top of packaged cabinetry.
Ideal storage conditions include:
- A level surface to prevent warping.
- Controlled temperature and low humidity.
- Protection from direct sunlight.
- Sufficient space for installers to easily access each cabinet box.
Preparing for Installation Day
A successful installation day begins with a fully ready home. Ensure pets are secured, pathways are clear, and any remaining demolition work is complete. Installers will begin with base cabinets, using laser leveling equipment to establish a perfect reference line along the walls.
