Water Pooling Under the Basin? You Could Have a Blown Seal

A leaking kitchen sink can cause serious structural damage before you even notice a puddle. Many times, the leak is not coming from the pipes themselves, but from a failed silicone seal around the rim of the sink.

Think of your sink seal like the weatherstripping on a window—if it dries out, shrinks, or cracks, water will find a way through. Every time you wash dishes or wipe down the counter, water slips through the gap and soaks into your expensive wood cabinetry. Jason, Curtis, and our licensed team can diagnose the source instantly and determine if a clean re-seal or a full basin swap is your best option.

Is Your Undermount Sink Sagging or Pulling Away?

Undermount sinks look beautiful, but they carry a massive amount of weight when filled to the brim with water and heavy cast-iron pans. If the original installer relied solely on weak construction glue instead of heavy-duty mechanical mounting clips, the sink will eventually begin to sag and pull away from the stone countertop.

When a sink drops even a fraction of an inch, it tears the waterproof seal. Left unchecked, that small sag can cause the entire basin to collapse completely, breaking your drain pipes and causing a massive indoor flood. Our Eastside plumbing specialists use rugged, commercial-grade support clips and framing anchors to ensure your sink stays locked in place forever.

Low Water Pressure or Slow Drains at the Sink?

If your sink takes forever to empty or your garbage disposal keeps backing up, the problem often sits right at the sink strainer assembly or the P-trap line beneath it.

Food waste, grease, and hard water minerals build up inside the drain connections, reducing the physical space water has to pass through. We can cleanly disassemble the plumbing beneath your basin, clear out the stubborn restrictions, and rebuild the drain system with durable materials. If your sink is older, these drainage slowdowns are often warning signs of aging, corroded metal pipes hidden back in the wall structure.

New Kitchen Sink Installation? Here Is What to Expect

We carefully extract your old sink basin, inspect the structural health of your countertop cutout, clean away old silicone residue, and drop in or under-mount your beautiful new fixture.

Selecting a kitchen sink involves more than just picking between stainless steel, fireclay, or composite granite. You must measure the exact depth of the basin to ensure it aligns correctly with your existing wall drain height, choose the correct hole configuration for your accessories, and make sure your garbage disposal can mount securely. We walk you through every step and handle the entire process from start to finish.

Real Story: Issaquah Homeowner Avoids a Countertop Disaster

A homeowner in Issaquah noticed that the cabinet divider between her kitchen drawers was constantly damp. She feared she would have to rip out her entire expensive granite countertop to fix the issue.

Curtis came out to inspect and found that the undermount stainless steel sink had completely detached from the stone on the backside. Instead of a costly remodel, we safely supported the granite, cleanly removed the old basin, installed a durable new deep-basin sink with heavy-duty mechanical brackets, and re-sealed the entire perimeter. The fix was clean, permanent, and saved her thousands of dollars.

Is It Time to Replace Instead of Repair?

If your sink is deeply scratched, rusted through, holds permanent odors, or has structural cracks, it is far wiser to install a brand-new one.

Old sinks are like old shoes. You can try to patch them, but they eventually lose their structural integrity and hygienic value. Upgrading to a modern, deep single-basin or a functional workstation sink completely changes how you use your kitchen, while adding instant equity to your home.

FAQs: Kitchen Sink Installation

Q: Can I change from a double-basin to a single-basin sink during a replacement?

A: Yes! As long as the outer dimensions fit your existing countertop cutout, changing the basin style is very common and usually requires only a minor adjustment to the drain pipes underneath.

Q: How long do I have to wait to use my new sink after installation?

A: We use premium waterproof silicone to seal the basin edges. It typically requires 24 hours to cure completely before you can expose it to heavy water or strain.

Q: Can you reinstall my old garbage disposal onto the new sink?

A: Absolutely. If your current garbage disposal is in good structural health, we will cleanly transfer it over to the new sink basin, replacing the mounting flange and gaskets to prevent leaks.

Q: What is the difference between an overmount and an undermount sink?

A: Overmount (drop-in) sinks have a visible rim that sits on top of the countertop. Undermount sinks attach directly beneath the countertop surface, creating a seamless rimless look that makes cleaning countertops incredibly easy.
