Is your under-mount sink pulling away from the countertop, becoming loose or beginning to separate?
HANDLD professionally repairs and re-secures eligible under-mount sinks across Toronto. We remove failed adhesive, prepare the attachment surfaces and support the sink while the new bond cures.
Signs Your Under-Mount Sink May Need Repair
Under-mount sink attachment problems often begin with a small gap or slight movement before the sink becomes noticeably loose. Look for these common warning signs:
Visible Gap
A gap between the sink rim and the underside of the countertop may indicate that the existing attachment is beginning to fail.
Sink Movement
Your sink should not move or shift during normal use. Movement may indicate a weakened attachment.
Deteriorating Adhesive
Older adhesive or attachment materials can deteriorate, allowing the sink to begin separating from the countertop.
Sink Pulling Away
One side of the sink may begin to drop or pull away before the entire sink becomes loose.
Water Around the Sink Edge
A failed sink-to-countertop connection may allow moisture into areas that should remain sealed.
Partially Detached Sink
A sink that has visibly dropped or detached should be assessed before it continues to be used normally.
Why Is My Under-Mount Sink Separating From the Countertop?
Under-mount sinks are secured beneath the countertop rather than resting on top of it. Over time, the attachment can weaken because of aging adhesive, moisture, movement, installation conditions or repeated stress on the sink.
​
The first warning sign may be a small gap between the sink and countertop. In other cases, one side of the sink may visibly begin to drop.
​
HANDLD reviews the existing sink, countertop and attachment conditions to determine the appropriate repair method. A separating sink should not simply be covered with new caulking when the sink itself is no longer securely attached.
Signs Your Under-Mount Sink May Need Repair
In many cases, an under-mount sink that has separated from the countertop may not need to be replaced.
​
If the sink, countertop and surrounding installation are in suitable condition, the existing sink may be cleaned, re-secured and properly supported while the new adhesive cures.
​
Every installation is different. A cracked countertop, damaged sink, unsuitable mounting conditions or plumbing complications may require additional work or a different solution.
​
Send us photos of the sink and the area where it is separating. HANDLD will review the visible condition before confirming the repair scope and scheduling your service.

Common Under-Mount Sink Repair Questions
Can the existing sink be saved? Often, yes. If the sink, countertop and surrounding installation remain suitable, the existing sink may be re-secured without replacement.
Does a separating sink need to be replaced? Not necessarily. The separation may be caused by a failed attachment rather than damage to the sink itself.
Can you just add more caulking? No. Caulking should not be used to conceal a sink that is no longer securely attached to the countertop.
Why is my under-mount sink separating from the countertop? The attachment may weaken because of aging adhesive, moisture, movement, installation conditions or repeated stress on the sink.
What if the countertop is damaged? Countertop damage may affect whether the sink can be safely reattached and could require work outside the standard repair scope.
Can you repair a sink that is separating on only one side? Potentially. HANDLD will review photos of the sink, countertop and separation area to determine whether it is suitable for reattachment.
Can I continue using a sink that is pulling away? Continued use may place additional stress on the weakened attachment. Limit use and submit photos to HANDLD so we can review the visible condition.
Does the repair include removing the old adhesive? Failed or deteriorated adhesive is removed as required before the appropriate attachment surfaces are prepared and the sink is re-secured.
How long does the adhesive need to cure? Curing requirements vary depending on the adhesive and repair conditions. Your Handlr Technician will explain how long the sink must remain supported and when it can be used again.
What if plumbing needs to be disconnected or repaired? Plumbing work is not automatically included. If additional plumbing work is required, HANDLD will explain the recommended scope before proceeding.
