Our Expert Undermount Sink Cutout Solutions
Creating precise and durable undermount sink cutouts in granite, quartz, and marble requires specialized skills and tools. We ensure every cutout fits the sink flawlessly, maintaining the integrity and appearance of your countertops.
Precision Cutouts for Granite, Quartz, and Marble
We carefully measure and plan each cutout to fit your undermount sink perfectly, accounting for sink size, bowl configuration, and countertop thickness. Granite, quartz, and marble are dense materials that demand exact cutting to avoid chipping or cracking.
Our process includes verifying edge smoothness and sizing to create a seamless fit. We also bevel the cut edges underneath to support water drainage and sink mounting. This precision protects your countertop and prevents leaks or damage over time.
Diamond-Blade Cutting Tools and Techniques
We use industrial diamond-blade cutting tools specifically designed for natural and engineered stone surfaces. These blades provide clean, smooth cuts essential for maintaining your granite or quartz countertop’s structural strength.
Our technicians use controlled cutting speeds and specialized methods to minimize heat and vibration, which reduces the risk of material fracture. During the process, we test-fit the sink repeatedly to ensure the final cutout matches the exact required dimensions. Polishing the edges completes the cutout to blend with your countertop’s finish.
Professional Undermount Sink Installation Process
We ensure each undermount sink installation is precise and durable, focusing on accurate measurements, secure mounting, and flawless finishing. Our process adapts to various countertop materials, such as granite, quartz, and marble, to deliver a perfect and lasting fit.
Templating and Custom Measurement
We start by creating detailed templates specific to your countertop and sink model. Using precise digital measuring tools, we capture exact dimensions to account for sink shape, bowl depth, and countertop thickness. This reduces errors and prevents costly adjustments later.
Our measurements include critical factors like edge thickness and overhangs, ensuring the sink fits flawlessly beneath the countertop. We also verify plumbing alignment and cabinet dimensions to avoid complications during installation. This tailored approach supports all sink brands we work with, including Kohler and Blanco.
Anchoring and Mounting
Systems
Securing the undermount sink requires specialized hardware designed for the sink’s weight and countertop material. We install heavy-duty brackets and clips calibrated to distribute the sink’s load evenly. This prevents sagging and maintains stability over time.
We apply high-quality adhesives and waterproof sealants that allow for material expansion while preventing leaks. Larger sinks receive additional reinforcement, such as steel supports or custom fabricated braces, to ensure consistent strength. Alignment checks guarantee the sink sits level and properly positioned relative to cabinetry.
Polishing and Edge Finishing
After the sink is mounted, we polish the cut edges of the countertop around the opening to match the surface finish precisely. This step ensures smoothness and a seamless transition from countertop to sink.
Our technicians use diamond polishing pads suited to granite, quartz, or marble, delivering consistent gloss and texture. We also bevel edges beneath the sink slightly to promote efficient water drainage and reduce wear on sealant lines. Final inspection confirms that edges are chip-free and present a professional appearance.

In bathrooms, we prioritize compact designs that blend functionality with aesthetic appeal. Our installations emphasize secure mounting and waterproof sealing to avoid leaks and prolong countertop life.
New Countertops and Retrofits
We install undermount sinks during new countertop installations or retrofit existing granite and quartz surfaces. With new countertops, we coordinate sink placement from the start to ensure a flawless cut and fit.
For retrofits, we carefully cut existing granite slabs using professional-grade equipment. This minimizes the risk of cracks or chips. We also reinforce the countertop and test the installation thoroughly to maintain structural integrity and prevent future issues. Our approach respects the existing layout, with minimal disruption to your space.

Can you cut existing countertops for undermount sinks?
Yes, we can cut existing granite, quartz, and marble countertops for undermount sink installation using specialized diamond blade tools and dust extraction systems. The process requires careful measurement, precision cutting from underneath when possible, and extensive dust protection for your home. We assess countertop support structure and may need to add reinforcement brackets for proper sink mounting. Success depends on countertop accessibility, existing plumbing configuration, and adequate workspace around the sink area.
