Sink & Faucet Repair in Kitchener, Waterloo & Cambridge
Stop drips, restore pressure, and upgrade fixtures without the mess.
A dripping kitchen faucet or a running toilet can waste thousands of litres a year and stain fixtures with hard-water mineral buildup common in Guelph and Waterloo. Flowline repairs cartridges, valves, supply lines, and drains; replaces tired fixtures; and installs customer-supplied units when they've already chosen a model.
Under-sink leaks often come from corroded supply lines, loose P-traps, or failed dishwasher tailpieces — we fix the cause, not just the symptom. For bathrooms, we handle shower valves, tub spouts, and pressure-balancing issues that scald or surprise you when laundry cycles.
Every visit includes shutoff verification, flow test, and cleanup. Flat-rate quotes cover standard replacements; we flag custom stone tops or wall-openings before work starts.
