Professional Sink Repairs for Your Home
Leaky Faucet Repair
Even the smallest drip can waste litres of water and cause costly damage over time. Our technicians repair all types of faucets—whether it’s a classic compression tap or a modern single-handle model. We diagnose the root cause of the leak, whether it’s a worn-out washer, faulty seal, or corroded valve, and restore your sink to full working order.
Drain Replacement and Repair
Rusty, cracked, or misaligned drain assemblies are more than a nuisance—they can damage cabinetry and create persistent leaks. We remove failing components and replace your sink drain with top-quality parts that are sealed tight and built to last. Every connection is tested to ensure proper drainage and long-term reliability.
Sink Installation Services
Replacing a damaged sink? Updating your bathroom or kitchen? We provide full installation of new sink fixtures, including faucet hookups, drain alignment, and sealing. We handle the entire process—from carefully removing the old sink to testing every connection—so your new fixture performs exactly as it should without hassle or guesswork.
Clogged Drain Solutions
If water is pooling in your sink or draining at a crawl, DIY cleaners won’t cut it. Our team uses non-invasive tools to clear even the most stubborn clogs, whether caused by grease, hair, or foreign objects. We also provide long-term solutions to help prevent future clogs, like installing strainer baskets or making small plumbing upgrades tailored to your setup.
Pipe Repair Under Sinks
Leaks from pipes hidden beneath your sink can lead to structural damage, mould growth, or warped cabinetry. We inspect all under-sink plumbing thoroughly and identify signs of corrosion, stress fractures, or loose joints. We replace or reinforce affected sections using modern fittings and pipe materials, protecting your home from future leaks and unnecessary repairs.

- Standing water under the sink or dampness inside cabinets
- Slow drains that don’t respond to plunging or drain cleaner
- Unpleasant odours from your sink that stick around even after cleaning
