Here is some helpful Tips on How to Assemble and Install Kitchen Cabinets: Use the stud finder to find and mark the studs along this line across the room. Dry fit your first cabinet into position and check for level across the top. If needed, shim till level. Now, predrill through the top framing piece into the wall studs and secure the cabinet into position with screws.
Measure and Mark the Wall:
Measure the height of the base cabinets. Most standard cabinets are 34-1/2” high. Add 1-1/2” for a standard countertop and 18 inches for the standard backsplash, (though a few designers now want a 20-inch backsplash to make room for small appliances). With an 18-inch backsplash, the overall measurement should be 54 inches from the floor to the bottom of the upper cabinets. If your flooring is not level, make sure that you measure from the highest point along the wall.
Draw a horizontal line across the wall at this 54-inch point which will function as a guide for hanging the cabinets. Make sure to use a level to assure this line is true horizontal.
Use a stud finder to find the wall studs. The wall studs are crucial to correctly strengthen the weight of the cabinets. Note: Pay careful attention to the placement of all electrical wiring and plumbing.
Secure Ledger Board:
Secure a ledger (support) board to the wall, screwing it into the marked studs to temporarily support the weight of the cabinets during the installation. Make sure the doors and hardware are removed from the cabinets to cause them to be lighter and easier to install.
Hang the Wall Cabinets:
Attach as many cabinets together as you’ll be able to safely lift and install on the ledger board — usually two. Use clamps to fix the stiles (the vertical pieces on the face of the cabinet frames) of the cabinets together and check for plumb, ensuring the fronts of the cabinets are flush.
Next, predrill and secure the 2 cabinets together at the stile with the screws. Affix one screw at the top and bottom in the front and back where the two cabinets meet.
Lift the cabinets onto the ledger board and check for plumb and level. Shim the cabinets if necessary.
Once you have shimmed for plumb and level, secure the cabinets into the wall on the studs. Make sure to predrill and affix the screws through the thicker framing piece along the top of the cabinets.
Check for plumb and level at the same time as you’re securing the cabinets. Repeat this procedure for all of the wall cabinets. If a gap exists between wall and the last cabinet, use a filler bar (supplied by the manufacturer) to enclose the gap. Prior to securing the last cabinet, measure, mark, cut and secure this piece to the side of the last cabinet.
After all of the cabinets are in place, attach the doors and hardware. Remove the ledger board when you’re completed installing the wall cabinets.
Install Base Cabinets:
If the floor isn’t level, find the highest point in the floor along the wall where the cabinets will be installed. It’s best possible to try to start the base cabinet installation as close to this high point as possible — it’s easier to shim under the cabinets on the lower spots to make them level with this first one, rather than beginning on a low point and having to trim the bottoms of the cabinets while working “uphill”.
Measure base cabinets and use the pencil and level to mark a level line on the wall from the high point in the floor to the cabinet height. Make sure to use a level to assure this line will be true horizontal. This is the guide to be followed for installation.
Use the stud finder to find and mark the studs along this line around the room.
Dry fit your first cabinet into position and check for level across the top. If needed, shim until level.
Now, predrill through the top framing piece into the wall studs (as shown) and secure the cabinet into position with screws. Re-check level after securing the cabinet.
Repeat this process till all of the base cabinets are installed. Attach the doors and hardware after all of your cabinets are in place.
