Your antique table’s legs are wobbly, even though no one has touched it in years.
The back of your chair moves whenever you lean back in it.
What made your furniture wobbly? And can you repair it?
Mumford Restoration has been repairing, restoring, and preserving furniture since 1982. We know our way around a bottle of glue!
For over 40 years, we’ve been helping our clients understand why antique furniture becomes loose. We have helped many people avoid damaging repairs and make informed decisions about how to address the problem.
Why Does Furniture Become Loose or Wobbly?
Over time, glue weakens, joints shift slightly, and furniture endures stress from various sources. These combined factors can make a piece of furniture unstable.
Well-made furniture is a collection of elements that rely on each other for strength and stability.
This tight system consists of:
mortise-and-tenon joints
dowels or pegs
hide glue (in the case of antique furniture)
Carpenter’s glue (for furniture made after WWII)
Glue is a critical part of the system. And the type of glue affects how a piece of furniture will react to certain conditions.
Hide glue was the standard adhesive for centuries. It was intentionally chosen because it is:
strong
reversible
repairable
However, hide glue is not permanent. No glue is!
After decades of use and environmental exposure, hide glue gradually:
dries out
weakens
loses its grip within the joint
Even modern carpenter’s glue does not offer a permanent bond.
Carpenter’s glue can lose its grip when:
The wood experiences temperature or humidity changes that cause the wood to swell or contract
The furniture is placed under stress, such as when a child leans a chair back so that it rests only on its back legs
When the glue can no longer maintain a bond with the wood, the furniture’s joints wiggle and become unstable.

Is It Normal for Antique Furniture to Become Loose?
Yes, all furniture becomes loose over time.
In fact, antique furniture was designed with the expectation that it would need to periodically be disassembled and reglued.
A wobbly chair or table does not necessarily mean the furniture is damaged. In many cases, it simply means it’s time for the chair’s expected maintenance.
Regluing is a normal part of maintaining antique furniture.
Photo Above: No material can last forever. So, occasional disassembly, cleaning, and regluing is a normal part of the furniture lifecycle.
What Causes Glue Failure in Antique Furniture?
Glue failure is the result of time, environment, and repeated stress, not a single event.
The most common contributing factors include:
long-term use and weight-bearing stress
natural aging of hide glue
small amounts of movement over time
environmental changes such as inconsistent temperature and humidity
Over time, these factors weaken the bond inside the joint until it can no longer hold securely.
Above: It's important to get your furniture repaired whenever you notice any movement in the joints. If you wait, the problem could worsen and cause significant damage!
Can Loose Antique Furniture Be Fixed Without Taking It Apart?
No, loose furniture cannot be effectively reglued without disassembly.
Proper repair of antique furniture joints typically requires:
disassembling the joint
removing old adhesive
reapplying appropriate glue
reassembling under controlled pressure
When you attempt to force glue into a joint, it actually doesn’t penetrate as far as you think. It often doesn’t get more than ⅛ or 1/16” past the visible joint. This distance is completely insufficient to encourage a strong bond.
The entire surface of the mortise and tenon must be covered in a thin layer of glue.
Additionally, failing to disassemble the furniture leaves dirt and old glue in the joint.
Since hide glue breaks into sharp crystals as it ages and fails, this will wear down the joint and make it noisier!
In the case of modern carpenter’s glue, new glue cannot stick to old glue. The new glue will come into contact with the old glue, dry, and then will immediately fail to bond. The two layers of glue will simply slide back and forth across each other.
So, your furniture will continue to wobble, but you will have created extra work for the person who disassembles and reglues the chair. They will have to clean an extra layer of glue from the chair before they can begin work.

Should You Use Modern Wood Glue on Antique Furniture?
It depends on the age of the furniture, its historic significance, and your goals for the piece.
Traditional hide glue is preferred in antique preservation because it:
maintains historic integrity and character, as hide glue was the original type of glue used.
can be reversed with heat and moisture in the case of future adjustments or repairs
Modern adhesives such as PVA (polyvinyl acetate), commonly known as wood glue or carpenter's glue are:
strong
convenient
not reversible
Using modern glue in antique joints can complicate future repairs in the case of historic furniture that you are seeking to conserve.
However, if your furniture is modern, it is already held together by carpenter’s glue.
Even if your antique furniture originally used hide glue, carpenter’s glue might be the right choice for it now.
For example, if your furniture will be exposed to heat and humidity, carpenter’s glue is actually a better choice. Modern carpenter’s glue will not reactivate and become gummy and “workable” again if your chair or table is in a room that often becomes humid or warm.
Furthermore, carpenter’s glue lasts longer than hide glue, so you will likely not have to reglue it for quite some time.
If your piece of antique furniture is not a rare, museum-quality piece, you can absolutely use carpenter’s glue and not feel guilty.

Why Do DIY Repairs Often Make Wobbly Furniture Worse?
Your chair legs move. It seems as if it should be an easy fix. Just put a few screws in the leg or squeeze glue into the
Unfortunately, most repair attempts won’t have the long-term results you’re hoping for.
Common DIY attempts include:
using the wrong kind of glue
forcing glue into joints
gluing and clamping without proper disassembly
clamping at the incorrect angle
adding screws or nails
Furniture is a system. Furniture does move, but that movement is distributed across all of the joints. That means each joint actually moves very, very slightly.
Many well-intentioned repairs interfere with that system and don’t allow it to function properly.
These approaches can:
damage surrounding wood
distort the joint
make future restoration more difficult
reduce historical integrity
For example, inserting a screw into a joint doesn’t allow the joint the slight amount of give it needs. If the joint can’t give, the surrounding chair wood will and it often rips off of the chair, along with the screw!
Additionally, complex shapes can be a challenge for DIY-ers. Many chairs have a slight curve in their stiles (2 long pieces of wood that form the back as well as the back legs of the chair). If you don’t create a caul, you will not be able to clamp at the correct angle. The chair will continue to wobble and will now require additional cleanup before proper repair can begin.
Once a joint has been improperly repaired, correcting it often requires more extensive work.

What Are Signs of a More Serious Structural Problem?
While loose joints are generally expected (and normal), some indicate more significant issues.
Look for:
cracks in the wood near joints
missing or broken structural elements
joints that have completely separated
Many of these more severe issues resulted from improper DIY repairs, especially the use of screws and nails, as well as improper gluing.
These conditions may require more than simple regluing and should be evaluated carefully.

How Do You Properly Repair Loose Furniture Joints?
Professional repair focuses on restoring the entire system, which is the only way to stop movement and protect the
A restoration specialist will:
Methodically inspect for any screws or nails in the joints, and then remove them.
Carefully disassemble the piece of furniture
Remove the old adhesive from the joints
Ensure that the newly clean joints fit together properly and adjust the fit, if necessary
Reassemble using appropriate materials
Clamp at the correct angle
The goal is to make your furniture stable and functional, while preserving as much original material as possible.

When Should You Call a Furniture Restoration Professional?
It takes training and practice to properly reglue furniture.
Clients expect a quick weekend project when they try to repair their loose tables and chairs, but quickly get overwhelmed!
A professional furniture restorer can save you significant time, effort, and potential damage.
We recommend professional evaluation when:
the furniture is wobbly or unstable
joints move under normal use
previous repairs have failed and/or caused damage
the piece is valuable or sentimental
Early intervention can prevent a minor wobble from becoming more complicated structural damage.

Can Loose Antique Furniture Be Prevented?
Glue naturally ages, so looseness cannot be prevented. Moreover, it’s not supposed to be prevented! High-quality
However, you can take steps to keep your furniture in good condition and delay the regluing process.
Best practices include:
avoiding excessive stress or weight
maintaining stable environmental conditions
addressing minor movement early
avoiding improper repairs
Antique furniture is strong and durable, but it performs best when maintained thoughtfully.
