Faucet Repair in Northbrook, IL

The cartridge does the real work

Behind most single-handle faucets sits a cartridge, a small cylinder that controls flow and blends hot with cold. Inside are rubber seals and, in many designs, ceramic discs polished flat enough to seal without gaskets. A scratch from sediment or a seal dried out with age is enough to leave a steady bead of water at the spout.

Cartridges are model-specific, which is why matching the part matters. A near-fit will seat, then weep within weeks. When a brand has discontinued the exact piece, we say so plainly and discuss the replacement options.

Two-handle faucets work differently. Each handle drives its own stem against a seat, so a drip usually points to one side. Replacing the stem, the seat or both is a short job once the right pieces are in hand, and it often rescues a fixture whose style you actually like.

The aerator hides in plain sight

Unscrew the tip of most spouts and you find a small mesh screen called the aerator. It mixes air into the stream and catches debris. After a plumbing job, a water main repair or simply a few years of use, that screen collects grit and slows the flow to a dribble.

Soaking it in vinegar and brushing it clean takes minutes. If the same blockage returns repeatedly, we look upstream for flaking from an old supply line or water heater, which is a bigger story than a dirty screen. A licensed plumber northbrook il technician handles every job, never a day-labor shortcut.

Pull-down and pull-out sprayers add another failure point. The hose, its weight and the quick-connect fittings under the sink wear out, and a sprayer that drips from the head or will not retract is usually a hose problem, not a faucet problem.

Valves under the sink get ignored

Beneath every sink sits a pair of small stops, each a shutoff valve for one supply line. These are the first thing we reach for, since they let us work on the faucet without cutting off water to the house. In many older homes they have not been turned in decades and may weep or refuse to close.

A failing stop is worth replacing during the same visit. Otherwise you finish a good faucet repair and still have no way to isolate the sink the next time something leaks.

When replacement is the smarter call

A kitchen faucet replacement in Northbrook becomes sensible when the finish has peeled, the body has pitted, or the pull-down hose and spray head keep failing. It also makes sense when a remodel changes the sink or countertop and the old fixture no longer fits the holes.

If you already bought a fixture, tell us the model. We check mounting style, hole count and supply connections beforehand so the install is not stalled by a missing adapter. If you have not shopped yet, we explain what to look for in the parts and warranty support rather than pushing a brand.

Water in the village comes from Lake Michigan and is treated at the Village water plant, so most of the wear we see is ordinary mechanical aging rather than a local water quirk. A cartridge that lasted fifteen years has done its job.
