Kitchen faucet replacement

Pull-down, pull-out, touchless or bridge faucets. We check the number of holes in your sink or counter first, add a deck plate or soap dispenser where needed, and connect new braided supply lines.

Kitchen sink installation

Drop-in, undermount and farmhouse (apron-front) sinks. For undermount and farmhouse models we work with your countertop installer on the cut-out and mounting, then connect the drain, disposal and dishwasher.

Filtered and instant hot water taps

A separate drinking-water faucet for an under-sink filter or reverse osmosis system, or an instant hot water dispenser. For filtration of the whole house, see whole house water filter installation.

Bathroom sinks and faucets

Vanity sink swaps, pedestal sinks, wall-mounted sinks and vessel sinks – vessel sinks need a taller faucet or a wall-mount spout, so we confirm the pairing before you buy. We install single-hole, centerset and widespread faucets and replace pop-up drains at the same time.

Check this before you buy a new sink or faucet

What to checkWhy it matters
Number of holes and their spacingA single-hole faucet on a three-hole sink needs a deck plate; a widespread faucet needs three holes with the right spacing.
Sink type: drop-in, undermount or vesselDecides the mounting method and the faucet height you need.
Spout reach and heightTall pull-down spouts can hit a window sill or upper cabinet.
Shut-off valves under the sinkOld valves often seize or leak once they are turned; we replace them during the install.
Disposal and dishwasher connectionsA new sink bowl depth or drain position can change how the trap and disposal line up.

Repair the faucet instead?

A drip from the spout usually means a worn cartridge or O-ring, and low flow is often a clogged aerator – both are quick repairs. Replacement makes sense when the body is corroded, the base leaks into the cabinet or parts are no longer made. See why a faucet drips.

Sink and faucet installation FAQs

Swapping a faucet on an existing sink is usually a short visit. Installing a new sink and faucet together, or moving the drain, takes longer.

Tell us the make and model when you book. We check that it fits your sink and counter before the visit so there are no surprises on the day.

Not always, but old valves often stick or start leaking once they are turned. We test them during the install and replace any that don’t close fully.

Yes, as long as the faucet matches the number of holes in the sink or counter. A deck plate covers unused holes.

Undermount sinks look cleaner and make wiping the counter easier, but need a solid-surface counter. Drop-in sinks work with any counter and are easier to replace later.

It depends on the faucet, whether the shut-off valves and supply lines need replacing, and any filter or soap-dispenser connections. We give you the price before work starts.
