Got Questions?

Frequently Asked Questions

How much does a professional kitchen sink installation cost in 2026?

The labor for a standard sink replacement typically ranges from $250 to $1000. If the project requires countertop modifications, new plumbing lines, or a transition from a drop-in to an undermount style, costs can increase to $1,000 or more. We provide a firm, upfront quote once we evaluate your existing counter and cabinet structure.

How long does it take to replace a kitchen sink?

A standard "drop-in" sink swap usually takes 2 to 4 hours. Undermount or farmhouse sinks require more time because they involve specialized mounting brackets, adhesive curing, and often minor cabinet alterations to support the extra weight.

What is the difference between a drop-in and an undermount sink?

A drop-in (top-mount) sink has a rim that sits on top of the counter, making it the easiest and most affordable to install. An undermount sink is attached beneath the counter, creating a seamless edge that allows you to wipe debris directly into the bowl. Undermounts are generally preferred for stone or quartz surfaces but require professional-grade support.

Can I install a farmhouse sink in my existing cabinets?

Standard cabinets usually require modification to accommodate the deep "apron front" of a farmhouse sink. We must cut the cabinet face and install internal bracing to support the significant weight of fireclay or cast-iron models. There are "short-apron" models designed to fit standard cabinets with minimal changes.

Do I need to replace my garbage disposal when I get a new sink?

Not necessarily, but it is the most cost-effective time to do so. Since the plumbing is already disconnected, installing a new disposal adds minimal labor. If your current unit is over 8 years old or shows signs of rust, we recommend a replacement to avoid having to pull the plumbing apart again soon.

Why is there a gap between my undermount sink and the countertop?

This indicates that the silicone seal has failed, or the mounting clips have loosened. If left unaddressed, water will seep into the cabinet below, leading to mold and wood rot. We reseal and retighten these connections to ensure a waterproof bond between the sink and the stone.

Can you replace a sink without damaging my granite or quartz counters?

Yes. We use specialized tools to break the old seal and remove the basin without putting stress on the stone. If the new sink fits the existing cutout, we can perform a clean swap that preserves your high-end surfaces.

What is a "workstation" sink and is it worth the upgrade?

Workstation sinks feature built-in ledges that hold accessories like cutting boards, colanders, and drying racks. They are highly efficient for small kitchens because they turn the sink area into a multi-functional prep space. We ensure the plumbing is configured to handle the larger footprint of these units.

Why is my stainless-steel sink making a loud "clanging" noise?

This is usually due to a lack of sound-dampening pads or undercoating. Higher-quality sinks come with thick rubber pads to absorb vibration. During installation, we can apply additional sound-deadening materials to reduce noise from the faucet and garbage disposal.

Do you provide emergency sink repairs if mine is leaking into the cabinet?

Yes. A leaking sink seal or a cracked basin can quickly ruin your kitchen cabinetry. We offer 24/7 emergency service to stop the leak, secure the basin, and replace any failing components to prevent structural water damage to your kitchen.
