For your convenience, this post has links to Amazon.

There are many reasons that can be behind a sagging cabinet. In some cases, it is due to poor support or water damage to the particle board. Cabinets can become weak and be frustrating for organization. Read on to find out how to fix sagging cabinets.

However, cabinets with poor support can sometimes be fixed or put back in place without removing them. You can simply fix it into its frame with new cabinet screws secured with a screw gun.

How To Fix Sagging Cabinets

Inspecting the Sagging Cabinets

Before you start, inspect the cabinets. You want to rule out problems like water damage, such as those caused by condensation of pipes or leaks, which would require a plumber.

As well, observe for signs of infestations like termites.

When it comes to kitchen cabinets, there could be other serious problems that involve the structural issues of the house. This is usually present when you notice not only the cabinets unhinging from the walls but also the kitchen countertops separating from the wall. If in doubt, contact your builder (for newer homes still under warranty) or a building inspector to confirm your suspicions.

Sagging cabinets can also result from an overload of items in them. If the cabinet is not properly constructed, it can damage over time. You can add support for the cabinets, store lighter items in top cabinets, or replace the cabinets with new strong material.

How to Fix Sagging Cabinets by Adding Support

Option 1. Single Shim Method

If you have cabinets with sagging hinges, you need to fix it in a way that when you open up the cabinet enough resistance will be against the wall so it doesn’t sag.

The force from opening these cabinet doors usually affects the small shim. The plastic may hold up. If it doesn’t, cracks will start appearing on the cabinets.

Option 2. Multiple Shims Method

This method is more effective than the first one. This method involves placing 3/8“ thick by 1” wide wood shims between each hinge. When the cabinet door rests against it, the shims give support so it won’t sag down.

If your cabinets are really sagging, use more shims. You can add two sheets of shim behind each hinge. If the sagging is less, place one sheet behind the hinge. Add as many shims until it is fixed.

How To Fix Sagging Cabinets Using Shims

A sagging cabinet means something is wrong somewhere. Cabinets may sag because of poor original installation, water damage, or weak screws, among other reasons. You can fix the cabinet yourself if it is not too damaged.

Step 1

Cut a 2-by-4 on the cabinet countertop and place blocks that will fit between them.

Attach wood shims between the blocks to keep the cabinet firm.

If the top is made of granite or any other fragile material, place two 2-by-4 on the top and apply pressure to support it. Also, apply pressure to all the sides of the cabinets to prevent further damage.

Step 2

Loosen the cabinet screws to lift the cabinet and place the shims under it. If you find it difficult to lift the cabinet, place the shim at the bottom of the block so it is angled.

Then, you can lift the cabinet gently. Use this for all the sides of the cabinet that are sagging.

Step 3

Drill a hole into the original holes, about 3/16 inches – if the existing holes are too large. Angle the holes to help the cabinet move forward and prevent the screws from bending.

Then, attach the cabinets tightly to the wall with screws. The screws should have flat heads, with large and round structures. You can use the help of a screw gun for drywall.

Step 4

If you have an arch around your cabinets, drill holes angled towards the 2 by 2 frame of the arch. Fix 4-inch screws into the front area of the cabinet.

Step 5

Drive in the new screws along the sides, below and above the existing screws. If any of the screws miss the hole, replace it until each of the old screws has a replacement. When all is set, drive in the old screws tightly.

However, a tip you can consider is to measure the opening of the cabinet. This will ensure the new attachments are going fit to the size on both sides.

How To Fix Loose Cabinet Doors

1. Make sure the screw is tight. The door may have come off as a result of the hinge sliding against each other.

2. If the cabinet is still loose, check the door screws and cabinet screws – tighten them. Change and replace the old screws, if it doesn’t tighten. Using fatter or longer screws, you can fill the holes with a wood filler for a tight connection.

How To Fix Badly Aligned Cabinet Doors

1. Undo the cabinet screws on both hinges, to change their vertical height. You can adjust the screws a few mm up and tighten it back.

2. You can adjust the sides of the doors by turning the screw on both hinges.

3. For better adjustment, screw the top in one way and the bottom in another.

Frequently Asked Questions

What makes cabinets pull away from the wall?

Cabinets that are not supported will end up sagging. There are two methods of attaching a cabinet to the wall – the toe kick method and the French cleat method. With the toe kick method, you need a piece of wood under the cabinet to attach to the floor using screws.
Over a while, cabinets begin to sag due to wear and tear from different causes. The French cleat method ensures the cabinet is supported tightly so it doesn’t come off the wall.

A cabinet may also sag if it isn’t properly installed. Using small nails can be a factor. If this happens, you need to reinstall it properly. You can hire a contractor if you can’t fix any of these issues.

What type of glue can I use for my cabinet?

Some people fix cabinets with glues. This helps to strengthen your cabinet doors so it doesn’t sag quickly.

Different types of glue are available, you have to know which one works best for you. Superglue is one of them. The only problem is it has chemicals that may stick around the edges and pollute plates that are used to serve foods for eating.

Another option is wood glue. This is great for sagging wooden cabinets because it’s what carpenters use. You can also try epoxy resin.

Polyurethane glue is also good. You need to work fast to align all the pieces because this glue sticks quickly.

Using glue to fix sagging cabinets involves patience.

Why Are My Cabinets Dropping From The Ceiling?

Dropping ceilings may be a result of not attaching the cabinets well. The installers may have been in a hurry to set up the cabinet which could have missed some of the steps. Another possible cause may be the wrong placing of installation screws.

These cabinets need to be unloaded before they can be fixed. A prop may be used between the counter and cabinet bottom to lift it tight to the ceiling.

The dropping ceiling is usually noticeable from inside the cabinet box. With careful inspection, you can determine the problem.

Use a 3/16 inch drill to make a hole. Then use a screw gun to attach the cabinets to the ceiling and wall.

Takeaway

There are several ways to fix sagging cabinets. Make sure you inspect the problem areas before carrying out the solution. For example, to see if the problem is caused by water damage or termites.

To correct a sagging cabinet that is caused by poor support, one of the methods is to place cabinet screws in the right places. Use wood shims for support and a drill or screwdriver to attach the screws into the studs.

If they are kitchen cabinets, then basic understanding of power tools and home building (studs, screw locations) is still important for how to fix sagging cabinets. Hiring a professional cabinet installer is a good option, too.

A sagging cabinet is an issue that is common in every household. It is bound to happen, no matter how you take care of cabinets or how it was constructed.
