Step-by-Step Guide
A comprehensive walkthrough of assembling and installing your KitchenMark kitchen units — from site preparation through final handover.
Installation Steps
Clear the kitchen space completely and protect flooring with dust sheets
Measure wall heights, depths, and widths to ensure accurate unit positioning
Locate and mark wall studs — essential for secure cabinet mounting
Check that walls are level and plumb using a spirit level
Ensure electricity, plumbing, and ventilation are disconnected or isolated
Remove old units carefully, taking care with electrical connections
Lay out all components and verify against the delivery checklist
Assemble the first base unit on a flat surface before installation
Use a cordless drill for all screw fixings — pre-drill holes to prevent splitting
Attach the adjustable feet to the bottom of each unit
Connect units together using connector screws at the rear and sides
Ensure all joints are tight and square using a carpenter's square
Position the first unit against the wall and check it's level both horizontally and vertically
Shim under the feet as needed to achieve a perfect level — this is critical
Screw the unit to wall studs using appropriate anchors
Add subsequent units and connect them with connector screws
Check regularly with a spirit level as you progress
Maintain consistent heights across all base units before fitting worktops
Ensure all base units are perfectly level before worktop installation begins
If mitering worktops, cut angles carefully and seal all exposed edges
Apply silicone sealant along the top edge of cabinets before laying the worktop
Position worktop and secure using figure-eight fasteners (allows expansion/contraction)
Do not screw directly through the top of units — use mounting brackets underneath
Leave a 10mm expansion gap between the worktop and any wall
Allow doors and drawers to acclimatize in the kitchen for 24–48 hours before hanging
Assemble drawer boxes completely before fitting into their openings
Install door hinges and adjust for perfect alignment — use a spirit level
Fit drawer slides to both the drawer box and cabinet interior
Check door and drawer gaps are even all around (typically 2–3mm)
Fine-tune hinge and slide adjustments until movement is smooth
Measure the backsplash area carefully, accounting for worktop thickness
Install backsplash material (tile, splashback, or cladding) according to manufacturer instructions
Seal gaps between backsplash and worktop with quality silicone sealant
Apply matching trim or edge cappings where required
Install any additional shelving or open storage elements
Apply final sealants and finishes as per product specifications
Reconnect all plumbing connections and test for leaks
Reconnect electrical appliances and check all functions work correctly
Test all doors and drawers open and close smoothly without sticking
Inspect all screw fixings and tighten if needed
Clean all surfaces thoroughly before handover
Keep all documentation, guarantees, and care instructions for future reference
Spirit level (laser level recommended)
Cordless drill with bit set
Screwdriver set (Phillips and flat head)
Carpenter's square
Measuring tape (at least 5m)
Pencil for marking
Shims (wooden or plastic)
Countersink bits for screw holes
Always work with a helper — do not attempt cabinet installation alone
Wear safety glasses and work gloves throughout
Ensure good lighting in the work area to avoid mistakes
Take regular breaks to maintain concentration
Keep children and pets away from the installation area
Turn off electricity to the kitchen before beginning any work
Level, Level, Level
The most critical aspect of kitchen installation is ensuring all base units are perfectly level before worktops are fitted. Use a quality spirit level (preferably laser) and shim as needed.
Screw to Studs
Always screw units to wall studs for maximum security. Use appropriate anchors (typically M8 bolts or heavy-duty plugs) and tighten firmly.
Allow for Movement
Wood expands and contracts with humidity. Leave 10mm gaps at walls and use figure-eight fasteners under worktops to allow for natural movement.
