3 Potential Problems with Undermounting Sinks in Granite and Quartz Countertops
Serving Portland OR, Vancouver WA, and the Oregon Coast
One of the many advantages of granite and quartz countertops in a kitchen is the unique option to “undermount” a stainless, composite, or cast-iron sink.
Not only do they look great, but they are supremely functional because the stuff destined for the garbage disposal can be easily wiped into the bowl without the annoying flange that is common with a top-mounted sink! But beware, improper installation techniques and sub-standard sealants can turn your dream counters into a nightmare of repair costs and inconvenience.
As your local countertop experts in Portland, Oregon, we want to help you stay informed. Below, we’ll discuss the three common mistakes made while installing an undermount sink in granite and quartz countertops.
1. Delamination Due to Inadequate Adhesive
Many granite and quartz installers bypass mechanical sink attachments like clips, rails, or brackets, and instead use silicone adhesive to secure the sink to the countertop. This is an inherently flawed method. The continuous strain of the sink on the countertop. The weight, moisture, and vibrations of the garbage disposal will cause it to literally pull away. This will result in moisture problems in your sink cabinet and costly repair bills to make it right.
2. Permanent Epoxies Turn Sinks into Sunk Costs
To avoid the limitations of silicone adhesive, some granite and quartz installers turn to permanent epoxy or plywood substrate. The problem with this method is the opposite — if the sink is defective or damaged, there’s nothing you can do. There’s no way to remove it or replace it without destroying the granite or quartz.
3. Failing to Seal the Deal
As with top-mount sinks, undermount sinks on granite or quartz need to be properly sealed. If not, it can lead to mold and mildew problems in the cabinet. For best results, it’s important to use high-quality caulking material or sealant and follow the manufacturer’s instructions explicitly.
Do Undermount Sinks Fall?
Yes – undermount sinks can fall for a number of reasons, including:
- Too much weight or stress: Excessive weight or stress can cause it to come down.
- Adhesive deterioration: Since adhesives break down over time, a sink can fall if it’s no longer secured.
- Improper installation: The sink may not have been installed properly.
- Corroded hardware: Hardware, like mounting clips, can corrode and fail to secure a sink.
- Lack of sealing: Undermount sinks have to be properly sealed to prevent mold and mildew.
