How to Install Cabinets in Kitchen – Step-by-Step Instructions

Once you have all your tools ready, clear the kitchen workspace. Remove obstacles and disconnect electrical outlets near the installation zone. Check wall conditions too, if they are sturdy and ready to support your cabinets.

After this initial preparation, follow these steps to ensure a smooth and precise cabinet installation. 

Step 1: Measure and Mark Your Layout

The first step is measuring your kitchen to ensure the cabinets fit perfectly. Start by identifying the highest point of your floor using a level. Mark a horizontal line from that point across the wall. This line becomes your base cabinet reference. 

Next, measure 34 ½ inches up from the floor to mark the top of the base cabinets.

Draw a second line 19 ½ inches above that to indicate the bottom edge of the wall cabinets. Standard kitchens leave an 18-inch gap between the countertop and upper cabinets. 

Use a stud finder to mark wall studs, as you will anchor your cabinets directly into them. Double-check measurements at least twice before drilling or cutting. 

Step 2: Start with the Wall Cabinets

Always begin with upper cabinets. Installing these first prevents you from leaning over lower cabinets and risking scratches or damage.

Start by attaching a temporary ledger board along your bottom wall cabinet line. This simple wooden support holds the weight of each cabinet while you position and level them. 

With a helper or cabinet jack, lift the first wall cabinet to its decided place. Align it with your marks and secure it using 2 ½-inch screws driven into the wall studs.

Once the first cabinet is level, move on to the next. Clamp the adjoining cabinets together and secure them through the frame sides with cabinet screws. After fastening each unit, recheck that it’s level and plumb. Continue across the wall until all the upper cabinets are properly installed.

After securing the row, remove the ledger board carefully. Fill small screw holes with caulk or touch-up paint for a clean finish.

Step 3: Install the Base Cabinets

Now shift your focus to the base cabinets. Begin with the corner or sink cabinet since these act as the anchor points for the rest of the run.

Place the first cabinet against the wall and check the level front-to-back and side-to-side. Use wood shims underneath the cabinet base where needed to correct uneven floors. Once level, fasten the cabinet through the back rail into the wall studs.

For adjoining cabinets, make sure the fronts are even. Clamp them together, and secure them with screws at the sides.. Continue along the wall and keep leveling each cabinet as you go.

Once all base cabinets are secure, check alignment across the entire run again and make any final adjustments to ensure everything is perfectly level.

Step 4: Add Fillers and Finishing Touches

The final step turns your installation into a polished kitchen. Fill any gaps between cabinets and walls with custom-cut filler strips, and add decorative trim or crown molding to the tops of wall cabinets for a finished look.

Install cabinet doors and drawer fronts last to avoid damage. Use caulk or sealant on small seams for a clean and professional appearance.

Finally, step back and admire your work. Wipe down the cabinets to remove dust or pencil marks, and enjoy a kitchen that looks cohesive and ready for countertops and quality hardware.

How Much Does It Cost to Install Kitchen Cabinets

The total cost of a kitchen cabinet installation depends on the size of your kitchen, the type of cabinets, and whether you do it yourself or hire a professional.

• DIY Installation: If you already have basic tools, expect to spend around $300 to $800 on fasteners and other materials. Stock cabinets typically cost $100 to $300 per linear foot, while semi-custom cabinets range from $250 to $600 per linear foot.

• Professional Installation: Hiring a professional usually costs $3,000 to $8,000 for a full kitchen, depending on your region and the complexity of the design. Labor alone can range from $50 to $250 per cabinet, with corner or specialty units on the higher end.
