Getting Ready for Cabinet Installation
Before you touch a single cabinet, preparation is vital. Good prep work saves hours of frustration later. You need the right tools and a solid plan.
Essential Tools and Materials Checklist
Gather everything you need first. Having tools handy speeds up the whole process.
| Tool Category | Specific Items Needed | Purpose |
|---|---|---|
| Measuring & Marking | Tape measure, Level (4-foot is best), Chalk line or pencil, Stud finder, Speed square | Accurate placement and ensuring straight lines. |
| Fastening & Drilling | Power drill/driver, Countersink drill bits, Long cabinet screws (3-inch recommended), Wood shims | Drilling pilot holes and firmly attaching kitchen cabinets to wall. |
| Support & Safety | Sturdy ladders or scaffolding, Cabinet jacks or temporary supports, Safety glasses | Keeping cabinets stable while securing them. |
| Finishing Touches | Caulking gun, Wood glue, Clamps (pipe or bar clamps) | Sealing gaps and holding pieces together during assembly. |
Prepping the Space
The room must be ready before the cabinets go in. Dust and debris can interfere with accurate marking.
- Clear the Area: Remove old cabinets, debris, and anything else in the way. You need open space to work safely.
- Check the Walls: Make sure the drywall or wall surface is sound. If walls are uneven, you might need to flatten them slightly first.
- Locate Studs: Use your stud finder to locate every wall stud where cabinets will sit. Mark the center of each stud clearly with a pencil. These points are where you will anchor the cabinets.
Layout Planning and Marking the Walls
This is perhaps the most important part of the cabinet installation steps. Mistakes here affect every cabinet placement.
Determining Cabinet Height
Most standard kitchen counters sit at 36 inches from the finished floor.
- Measure 36 inches up from the finished floor line. Mark this point on the wall where the base cabinets will sit. This is your baseline for the bottom of the base cabinets.
- For upper cabinets, the standard spacing between the countertop and the bottom of the wall cabinet is 18 inches. Mark 54 inches (36 inches counter height + 18 inches space) on the wall. This marks the top edge of your cabinet hanging brackets or the bottom line for securing wall cabinets.
Drawing Reference Lines
Use a long level and a chalk line to draw straight reference lines across the entire wall.
- Draw a horizontal line at the 36-inch mark for the base cabinets.
- Draw a horizontal line at the 54-inch mark for the upper cabinets. These lines guide the placement of your mounting hardware.
Step 1: Mounting Base Cabinets
Mounting base cabinets always comes first because they set the height reference for the rest of the kitchen.
Assembling Cabinets (If Necessary)
If your cabinets arrived flat-packed, you must assemble them first. Follow the manufacturer’s instructions carefully. Use wood glue on all joints for added strength before driving the required screws or fasteners.
Placing the First Cabinet
Start in a corner, usually the corner farthest from the sink or main work area, unless local codes dictate otherwise.
- Position the Cabinet: Lift the first cabinet into place against the wall. Rest the bottom edge directly on your 36-inch reference line.
- Check for Level and Plumb:
- Use a level across the top of the cabinet to ensure it is perfectly level side-to-side.
- Use a level on the side of the cabinet to ensure it is plumb (perfectly vertical).
- Shim as Needed: If the floor is uneven, slide thin wood shims underneath the cabinet until the level shows it is perfect. Shims fill the gap between the cabinet bottom and the floor.
Securing the First Base Cabinet
It is crucial to anchor this first cabinet firmly before moving to the next.
- Drill Pilot Holes: Locate the studs behind the cabinet back. Use a countersink bit to drill pilot holes through the cabinet’s back rail and into the wall studs. Aim for at least two screws per stud location.
- Attach to Wall: Drive long cabinet screws through the pilot holes. Make sure the screw heads sit slightly recessed (countersunk) but do not break the wood. These screws are vital for attaching kitchen cabinets to wall studs.
Installing Cabinet Mounting Rails (Optional but Recommended)
Some professionals use installing cabinet mounting rails (sometimes called ledger boards). This is a strip of wood secured horizontally to the wall studs first.
- Advantage: It allows you to simply rest the cabinet on the rail and then attach it, simplifying the cabinet leveling procedure.
- How to Use: Secure the rail precisely on your 36-inch line. Then, set the base cabinet on the rail and screw up through the cabinet’s bottom rail into the ledger board.
Joining Subsequent Base Cabinets
Once the first cabinet is secure, bring the next cabinet right up against it.
- Butt Them Together: Push the second cabinet tightly against the first. There should be no gaps between the cabinet faces.
- Temporary Clamping: Use pipe clamps or bar clamps to hold the two cabinet faces together tightly. This keeps them perfectly aligned while you join them.
- Drill and Screw: Drill pilot holes through the side panels of the adjacent cabinets—usually two or three holes spaced vertically. Use shorter cabinet screws (around 1 1/4 inches) for this step. Drive the screws in, pulling the cabinets tightly together.
- Continue the Process: Repeat this placement, leveling, and securing process for every base cabinet in the run.
Cabinet Leveling Procedure for Base Cabinets
Even after securing the first unit, check every subsequent unit for level and plumb before permanently fastening it to the wall. Shims placed under the first cabinet might slightly affect the line. Always re-verify level side-to-side and plumb front-to-back for every unit added.
Step 2: Hanging Upper Cabinets
Hanging upper cabinets requires extra care due to the height and weight. Never try to lift heavy wall cabinets alone.
Preparing for Wall Cabinets
The upper cabinets must align perfectly with the lower cabinets in depth and height.
- Verify the Line: Double-check your 54-inch reference line (which marks where the bottom of the upper cabinet should sit).
- Identify Studs: Mark the studs along the entire upper cabinet run, just as you did for the base cabinets.
- Check Cabinet Depth: Ensure all wall cabinets match in depth. If they don’t, you will need to use shims behind the shallower cabinets to bring them flush with the deepest one.
Using Cabinet Hanging Brackets or Rails
Most professionals use a ledger board system for securing wall cabinets, similar to the base cabinets, but placed higher up. This acts as a temporary support system.
- Install the Ledger: Secure a sturdy board (ledger) to the wall studs, making sure its top edge aligns perfectly with the bottom of where your cabinets will hang (e.g., 54 inches from the floor). This rail bears the cabinet weight temporarily.
- Using Cabinet Hanging Brackets: Some modern systems use specialized cabinet hanging brackets that screw into the wall studs first. The cabinet then hooks onto these fixed brackets. If using this system, follow the manufacturer’s specific instructions for mounting these brackets precisely on your height line.
Lifting and Placing Upper Cabinets
This requires at least two strong people or specialized cabinet jacks.
- Lift Safely: Lift the first wall cabinet. Set its bottom edge onto the ledger board or align the hanging hardware with the installed cabinet hanging brackets.
- Check Alignment: Check the cabinet for level and plumb immediately. Adjust shims between the wall and the back of the cabinet until it is perfect.
- Temporary Securing: Drive a few screws through the back rail into the wall studs just to hold the cabinet steady while you adjust the next one.
Joining and Securing Upper Cabinets
As with base cabinets, join the units together before final wall attachment.
- Clamp Together: Bring the next cabinet up, ensuring the front faces are perfectly flush. Clamp them tightly.
- Join Cabinet Sides: Drill pilot holes and drive cabinet screws through the side panels to secure the units to each other.
- Final Wall Attachment: Once the entire run of upper cabinets is joined, go back and install the long cabinet screws through the back rail into every marked wall stud. Use deep screws for secure attaching kitchen cabinets to wall.
If you used a ledger board, you drive screws up from the inside top of the cabinet into the ledger board, and screws down from the inside bottom of the cabinet into the ledger board. Once secure, you can remove the ledger board if it will be visible above the top cabinet or above the backsplash area.
Step 3: Final Alignment and Adjustments
Once all cabinets are attached to the wall, the look of the kitchen depends on fine-tuning.
Finalizing the Cabinet Leveling Procedure
Walk the entire run of cabinets, checking the level one last time.
- Base Cabinets: Check the countertop line (where the counter will sit) for level. Adjust shims under the toe-kick area if needed, though this should ideally be done before the final wall screws go in.
- Upper Cabinets: Check the top edge of the cabinets. If your walls were slightly wavy, you might have small gaps between the cabinet back and the wall. These are filled with paintable caulk later, but the cabinet must be held firmly in place now.
Adjusting Doors and Drawers
Kitchen cabinet hardware installation happens now. Hinges and drawer slides usually allow for significant adjustment.
Door Adjustment
Most modern hinges have three adjustment points:
- Side-to-Side (Gap Adjustment): Move the door left or right to adjust the gap between the doors.
- In-and-Out (Depth Adjustment): Moves the door closer to or farther from the cabinet frame. This is crucial for doors that won’t close flush.
- Up-and-Down (Height Adjustment): Moves the door up or down relative to its neighbors.
Use these adjustments to ensure all doors are perfectly straight and gaps are even across the entire kitchen run.
Drawer Alignment
Drawer slides usually have clips or adjustment screws. Adjust these until the drawer fronts line up precisely with the door faces.
Step 4: Installing Kitchen Cabinet Hardware
With the structure set, it is time for the final touches—handles and knobs. Accurate placement makes the kitchen look professional.
Measuring for Hardware Placement
Consistency is vital here. Decide on a standard distance from the edge and the top/bottom of the door or drawer.
- Draw Guidelines: Use a square and a tape measure to draw faint pencil lines on every door and drawer face indicating exactly where the hardware centers will go. For drawers, the center line is usually half the height of the drawer face.
- Use a Template: The easiest way to ensure perfect repetition is using a specialized template or making your own template from scrap wood for your specific handle size.
Attaching Handles and Knobs
- Drill Holes: Drill pilot holes carefully, usually from the inside of the door/drawer toward the front. This prevents the wood veneer from chipping or blowing out on the visible side.
- Attach Hardware: Insert the screws from the inside, aligning them with the pilot holes, and secure the handles or knobs.
Specialized Considerations for Diy Kitchen Cabinet Mounting
Tackling this as a diy kitchen cabinet mounting project requires attention to specific details that pros handle routinely.
Working Around Obstacles
If you have plumbing (like a sink base) or range cutouts, plan for those first.
- Sink Base: This cabinet is often installed slightly off-center to accommodate plumbing rough-ins, but its top edge must still align perfectly with the other base cabinets.
- Corner Cabinets: Corner cabinets often use specialized jigs or require careful measurement. If you have a blind corner cabinet, it is usually installed last, using its sides to brace against the adjacent standard cabinets.
Handling Different Cabinet Back Styles
Some older or very cheap cabinets might lack a full back panel or have a thin fiberboard back.
- If the back is thin, you absolutely must rely on installing cabinet mounting rails or heavy bracing, as the thin back cannot bear the load or maintain rigidity for securing wall cabinets directly to studs. Use the thickest possible screws to go through any wooden rail into the wall studs.
Managing Varied Wall Surfaces
If your wall is not standard 2×4 framing (e.g., masonry, brick, or metal studs), you must change your anchoring method.
- Masonry/Concrete: Use a hammer drill and specialized masonry bits. Anchor using lag shields or concrete screws, ensuring the anchor goes deep enough to bite firmly.
- Metal Studs: Standard wood screws will not hold. You must locate the metal studs and use specialized metal screws with a self-drilling or self-tapping tip, or use toggle bolts if studs cannot be located precisely.
Summary of Cabinet Installation Steps
Successfully mounting base cabinets and hanging upper cabinets relies on following this sequence precisely.
- Plan & Mark: Measure, find studs, and draw clear horizontal reference lines.
- Base Cabinets First: Install the first cabinet, level it, and secure it to the studs.
- Join Base Cabinets: Add the next base units, clamp them tight, and screw them together side-to-side.
- Upper Cabinets Next: Install temporary rails or brackets. Lift and secure the first upper cabinet, checking level and plumb.
- Join Upper Cabinets: Clamp and screw the upper cabinets together.
- Final Securing: Drive long screws through the back rails of all cabinets into the wall studs.
- Hardware and Adjustments: Install and adjust all doors and drawers to ensure perfect alignment before finally mounting the kitchen cabinet hardware.
This detailed approach ensures that your diy kitchen cabinet mounting results in a sturdy, professional-looking installation, utilizing proper methods for attaching kitchen cabinets to wall supports.
Frequently Asked Questions (FAQ)
What size screws should I use for attaching kitchen cabinets to wall studs?
For securely attaching kitchen cabinets to wall studs, most professionals recommend using 3-inch or 3 1/2-inch cabinet screws, provided your wall studs are standard 1 1/2-inch thick lumber. Ensure the screw passes through the cabinet’s back rail (usually about 3/4 inch thick) and penetrates the stud by at least 1 1/2 inches.
How far apart should I place the screws when securing wall cabinets?
When securing wall cabinets to studs, place screws about 12 to 16 inches apart, targeting every available stud location along the cabinet’s length. If you are using a ledger board, place screws in the top and bottom rails of the cabinet, ensuring at least one screw goes into a stud from the top rail and one from the bottom rail, even if the ledger board hides them.
Can I skip using shims during the cabinet leveling procedure?
No, skipping shims when the floor or wall is uneven is a common mistake. If cabinets are not perfectly level and plumb, doors will sag, drawers won’t close right, and the countertop installer will face major issues. Shims are cheap and essential for an accurate cabinet leveling procedure.
What is the standard height for upper cabinets above the countertop?
The industry standard for the gap between the finished countertop surface and the bottom of hanging upper cabinets is 18 inches. Always measure from the counter surface up to mark where the bottom of your cabinets will rest.
What is the difference between cabinet installation steps for base and upper cabinets?
The main difference is support and sequencing. Base cabinets sit on the floor and are anchored to the wall studs. Upper cabinets must be lifted, temporarily supported (often by rails or jacks), and anchored securely higher up the wall, often requiring two people for safety. Base cabinets must be installed before upper cabinets to set the height reference.
