How to Install Kitchen Cabinets

The following information is meant as a general guide for installing kitchen cabinets. If you are not an experienced carpenter, contractor, builder, remodeler, or seasoned DIY person, we strongly encourage you to seek out a professional to install your kitchen cabinets or at least have one assist you during this process.
  • Here’s what you will need to get started:
  • Tape Measure
  • Carpenter Levels (12” and 48”)
  • #2 Phillips screwdriver
  • Phillips Screw gun
  • Chalk line
  • Extension Cord
  • 2 C-clamps or Rubber Padded Furniture Clamps
  • Hammer
  • Electric Drill
  • Drill Bits (At least 3: 1/8”, 7/32” & 3/16”)
  • Step Ladder
  • Handsaw
  • Carpenter’s Square
  • Patching plaster
  • Pry bar
  • Wood shims (For shimming cabinets up from floor or out from wall)
  • Stud Finder (Optional)
  • Circuit Tester
Step 1 - Before you begin
  1. Check your order This should have been done upon delivery (See our Shipping Policy section) but it’s imperative you have a complete and accurate order before you begin the installation. Make sure the contents of the cartons match the product numbers on your order and kitchen plan. If there are any damaged, incorrect, or missing cabinets immediately contact Customer Service at 888-860-3252.
     
  2. Turn off gas, water, and electric. If you’re installing your cabinets in a new home, ensure the utilities are roughed in and turned off.
     
  3. Shut off the water line to your sink. Open the faucets to drain the water lines. Disconnect the water and waste lines. Unplug the garbage disposal. Remove the sink if you plan to reuse it. (It also reduces the weight of the countertop)
     
  4. Pull the refrigerator away from the wall. If it has an icemaker, be careful not to kink the tubing. Shut off the water supply to the icemaker. Disconnect the water line and unplug the electrical. Move the refrigerator to an out of the way location and near an outlet not affected by the reconstruction. Make sure the outlet you choose can handle the circuit load of the refrigerator. Plug it back in.
     
  5. If you have an electric stove or oven, shut off all circuit breakers for these items. Test it by trying to turn on the appliance. Unplug and remove the appliance(s). For gas stoves and ovens, the gas source will need to be shut off prior to disconnecting the appliance. Note: Natural Gas and Propane are highly explosive! We recommend this be done by a qualified contractor or local gas company representative. Once this has bee done, disconnect and remove the appliances.
     
  6. Shut off the valve that supplies water to the dishwasher. Disconnect the waste and water line. Shut off the power supply at the breaker box. Remove the dishwasher.
     
  7. Shut off power to the kitchen in areas where a lighting fixture or outlet might need to be moved during reconstruction. Use a circuit tester to make sure the power is off. Check both receptacles in a duplex outlet because they each could be on a different circuit.
     
Step 2 - Cover up and protect items
Before you begin removal of your old cabinets, if you’re not replacing the floor cover over it with heavy cardboard or old carpeting to protect it.
  • Remove the contents of your existing cabinets. Organize them in small boxes so you can find items when you need them.
  • Remove the upper wall cabinets first. Remove the counter top. Remove the base cabinets. Remove any mouldings or trim that may interfere with cabinet installation.
  • If you are relocating the sink or appliances, you will need to move the plumbing, gas, or electric services.
  • Patch and repair the walls and/or floor. Complete any reconstruction and finishing (i.e. painting) before you start installing your new cabinets.
     
Step 3 - Checking for uneven floors and walls
All home walls and floors shift and settle over time. Even new construction does not guarantee that your walls and floors are plumb, level or square. Your cabinets must be shimmed and adjusted to account for this unevenness. Before you begin cabinet installation, remove all cabinet doors, drawers, and shelves from cabinets to lessen the weight and enable you to clamp stiles together for installation
 
Floors
First check for unevenness in floors. Locate the highest point on the floor. Place one end of a straight 2 x 4 at the end of the cabinet run. Place a carpenter’s level on top and check the bubble. Check all around the room within 22” of the walls where base cabinets will be installed. Raise either end of the 2 x 4 until it is level. Mark the floor at the end that makes contact with the floor. This is a high point. Once the high point is located, strike a level line on the wall all around the room from this point of the floor using your level chalk line. (See figure 1)


Figure 1

 
Walls
Next check for unevenness in walls. Mark the outlines of all wall cabinets on the wall to check actual cabinet dimensions against your layout to ensure your design will work. (See figure 2) Using a straight 2 x 4, check the walls for uneven spots. Wall unevenness can cause cabinets to be misaligned resulting in “racking” or misalignment of the doors and drawer fronts. Where these uneven spots interfere, scraping or sanding off excess plaster can remove high spots. Low spots can be shimmed with thin pieces of wood or shingles.

Step 4 - Find the Studs  
Typical wall construction places wall studs on 16" centers. This means that every 16" you have the center of a 2 x 4 wall stud to support your cabinets. To locate a wall stud, there are wall stud finder tools available or you can tap on the wall and listen for a “solid” sound. Studs will be located near outlets. Mark location of all studs on wall surface. (See figure 3)

Step 5 - Install the Corner Wall Cabinet
Nail a 1" x 2" wood furring strip with its bottom edge on the tall or wall cabinet line that you previously marked. You must begin your installation in a corner. Measure from the corner to the first stud mark and transfer the measurement to the inside of the cabinet to be installed. Repeat this step for each and every stud. Now drill a 3/16" hole through the hang rail inside of the cabinet 3/4" down from the top and 3/4" up from the bottom. Raise 1" x 2" the cabinet up into place against the 1" x 2" wood furring strip and support it underneath with a wood t-brace made from scrap lumber (See figure 4). Fasten the cabinet to the wall with #8 x 2 1/2" wood screws. Do not fully tighten the screws.
Please note: When installing a blind wall cabinet, make sure the cabinet is pulled out from the wall the appropriate distance as called for in your kitchen plan.

Step 6 - Install additional Wall Cabinets
Follow instructions in Step #4 to hang the next wall cabinet. Do not fully tighten the screws. Using two C-clamps, align the vertical stiles of the adjoining cabinets and hold tightly together. Drill pilot holes at hinge level through the stile of the second cabinet and just barely into the stile of the first cabinet. Using #8 x 2 1/2” wood screws, tighten securely (See figure 5). Then, after making sure both cabinets are plumb and level, shimming where necessary, tighten all screws securely to the wall. Now continue this procedure around the room. It is important to secure all cabinets together before shimming for plumb and level. Screw the cabinets tightly to the wall once they are plumb and level.

Step 7 - Install Fillers and Valances
Fillers are needed to take up odd dimensions when cabinets are installed next to a wall. They also allow clearance for doors and drawers to operate properly when turning a corner with a blind corner cabinet. A filler may have to be cut to size when used to take up an odd dimension next to a wall. Hold the filler in place; turn it over and on the backside make a pencil mark at top and bottom where it should be cut. Join the two marks with a pencil line and saw along that line. Put the filler in place and drill a pilot hole at hinge level through the cabinet stile and into the filler. Attach filler to the adjacent cabinet by fastening together with three #8 x 2 1/2" wood screws (See figure 6). Valances are installed in a similar manner; however, if trimming is necessary, you should cut from both ends equally so the valance design remains symmetrical.

Step 8- Install Base Cabinet
Corner Blind Cabinet

First, put the base cabinets in place starting with the corner cabinets. If a base blind corner cabinet is used, pull it out of the corner to the proper dimension, as shown on your kitchen layout. Shim this cabinet up to the high spot line previously located. Attach loosely to the wall by screwing into the wall studs through the hanging rail with #8 x 2 1/2” wood screws as previously described. Attach filler to the adjacent cabinet and fasten the two cabinets together also using the same procedures (See figure 7). Base blind corner cabinets may be pulled out as necessary. A 3”filler is included with each base blind corner which must be used as an extension of the adjacent cabinet to provide necessary door and drawer clearance.

Easy Reach Corner Cabinet

If using a base Lazy Susan cabinet, apply a 1 x 2 strip to the wall at the proper height to support the countertop. Apply to both walls at right angles. These strips should be screwed to the studs and will provide support for the countertop once it is installed into the corner. It is usually better to fasten at least one cabinet in both directions to the Lazy Susan and be sure they are shimmed properly, attaching the countertop brace described above.

Once the corner cabinet is positioned properly into the corner, use the stud marks on the wall to locate the position of the screws for mounting the base cabinets to the wall. Drill a hole at the stud location through the back rail of the base cabinet approximately 3/4” from the top and into the stud. Attach the cabinet to the wall with the screws provided inside each cabinet. Be sure to use the shims under the cabinet base to bring it up to the previously established level line.


Figure 8

Corner Filler Cabinet

When using a base corner filler cabinet fasten the two adjacent cabinets to the filler by drilling through the stile at hinge level of the cabinets into the base corner filler. Screw them together. Place the three pieces into the corner as one unit and attach to the wall though the cabinet hanging rail as previously described. Now make sure all cabinets are plumb and level. Shim where necessary and tighten all screws (See figure 9). Install countertop braces as shown on the wall at the 34 1/2” horizontal base cabinet level line.

Step 9- Install Remaining Cabinets
The remaining base cabinets are installed in the same manner. Using two C-clamps, align stiles, drill and screw together as described in Step 5. Proceed around the room making sure all cabinets are plumb and level, shimming where necessary. Then tighten all screws. (See figure 10)
