Some DIY shortcuts look clever—until they start failing. We were called to a home in Rancho Cordova where the kitchen sink wasn’t set into a proper countertop at all. It was sitting on a piece of plywood cut from the cabinet top, with tile glued around the edge to “hold” it in place. The result? A wobbly rim, hairline gaps, recurring leaks, and a cabinet that was always a little damp.
If you’re searching for kitchen sink repair Sacramento, sink replacement Sacramento, or help with tile repair around a sink, here’s exactly how we solved it—cleanly, safely, and built to last.
Why plywood + tile under a sink always fails
Moisture wins. Plywood swells, moves, and delaminates when exposed to water. Around a sink, that’s guaranteed. Movement breaks grout. As the wood flexes, the tile and grout crack, opening invisible leak paths. No true support. A sink needs a rigid, water-resistant structure; makeshift tops sag and pull hardware out of alignment. Hidden damage risk. Persistent dampness leads to soft cabinet bottoms, musty odors, and, eventually, mold.
If any of this sounds familiar in Folsom, Fair Oaks, Elk Grove, Citrus Heights, Carmichael, Roseville, or Orangevale, you’re not alone—and it’s fixable.
Our assessment (and what we look for)
Before we touch a tile, we:
Check the cutout size and confirm sink type (drop-in vs. undermount—tile tops almost always call for drop-in). Inspect the cabinet structure, shelf/base condition, and cleats. Test shut-off valves, disposal, trap, and supply lines. Evaluate tile condition, lippage, grout integrity, and the substrate below. Plan how to save existing tile where possible (or match new tile cleanly if needed).
The right fix — step by step
1) Protect & prep
We mask the work area, protect adjacent counters/cabinets, and shut water/power to the disposal.
2) Careful demo
We remove perimeter tile and old grout surgically to preserve as much material as possible, then lift out the plywood “top” and scrape off old thinset.
3) Rebuild a proper substrate
Instead of plywood, we install cement backer board and solid cleats/support rails around the cutout. This creates the rigid, water-resistant platform a sink actually needs. Where needed, we add a waterproofing membrane for extra protection.
4) Set the new sink
For a tiled counter, a quality drop-in sink is the most reliable choice. We dry-fit for perfect alignment and set the sink with the right sealant, fastening hardware, and level.
5) Tile, grout, and seal
We re-tile the perimeter, align joints, and color-match grout so the repair blends in. Finally, we run a continuous 100% silicone bead at the sink/tile junction—your primary defense against future wicking and hairline leaks.
6) Plumbing & leak test
New basket strainer, disposal hookup, trap alignment, fresh supply lines as needed, and a full pressure/leak test. No drips allowed.
7) Finish & cure
We smooth the silicone bead, clean the tile haze, and review cure times so the seal sets correctly before heavy use.
The result
A crisp, solid, and code-sensible sink installation that looks built-in—not patched in. Tile lines are straight, grout is tight, and the silicone joint is clean and continuous. Water stays where it belongs, and the cabinet finally stays dry.
Total on-site time varies by tile condition and plumbing updates, but most projects like this land in the one-day to day-and-a-half range once materials are on hand.
Signs you should call a pro (sooner than later)
The sink rocks when you press on the rim. Cracked grout or dark, wet lines around the sink. A musty smell inside the base cabinet. Evidence of a plywood cutout used as a “countertop.” Recurring leaks at the strainer, trap, or supply lines.
If that’s you, we can help—without turning your kitchen into a long remodel.

FAQ: Kitchen sink repair in the Sacramento Area
How much does a kitchen sink replacement cost in Sacramento?
It depends on tile condition, plumbing updates, and the sink you choose. Simple swaps can be a few hundred; tile perimeter and substrate repairs add labor. Share photos and we’ll provide a clear estimate.
Drop-in or undermount on tile countertops?
On tile, drop-in is typically the best long-term option. Undermounts demand specialty profiles and can compromise tile edges if not done perfectly.
Can you match my tile and grout?
We’ll save and re-use your tile where possible. If replacements are required, we’ll propose the closest match and blend transitions so the repair looks intentional, not obvious.
My cabinet base is soft—can you fix that too?
Yes. We routinely rebuild water-damaged sink bases and bottoms. See our cabinet services:
