Kitchen Sink Installation Services in Phoenix, AZ
Installing a kitchen sink, especially an undermount model or one integrated with a new counter, requires precise sealing, alignment, and plumbing connections. Whether it’s a new installation or a replacement, relying on a professional ensures the sink is secure, the drain is leak-proof, and the disposal is correctly mounted.

Choosing Your Perfect Kitchen Sink
During a remodel or replacement, we help you think through the functional aspects of your new sink:
Bowl Configuration, deciding between a single, large bowl or a double-basin setup.
Material Selection, reviewing the benefits of stainless steel, cast iron, or composite materials.
Faucet Holes, ensuring the new sink has the correct number of pre-drilled holes for your chosen faucet and accessories.
Drain Location, checking if the new sink drain location aligns with the existing plumbing or if adjustments are needed.
Our Sink Installation Process
Our focus is on creating a long-lasting, watertight seal to prevent cabinet damage and costly leaks. We start by safely removing the old sink and cleaning the counter opening thoroughly. We then apply high-quality plumber’s putty or silicone caulk for a watertight barrier and use the correct mounting clips or epoxy adhesive to firmly secure the sink in place. Finally, we install the basket strainer, tailpiece, P-trap, and connect the disposal, all with secure seals.
