Burst Pipe Repair
Burst pipes can cause significant water damage in a short amount of time, demanding immediate repair to prevent structural deterioration and mould issues. Our emergency plumbers arrive fully equipped to quickly locate the problem and repair or replace the damaged piping. We act fast to shut off your water supply, remove any standing water, and perform professional repairs that get your plumbing system working again.
Drain Clogs
Serious drain blockages can result in backups, flooding, and potential sanitation hazards, making urgent attention necessary. Our technicians use professional tools, including augers, hydro jetting systems, and camera inspection technology, to locate and eliminate even the most stubborn clogs. We handle blockages in kitchens, bathrooms, and main drain lines, restoring flow efficiently without harming your plumbing.
Water Heater Failures
A broken water heater can disrupt daily routines and potentially cause water damage if left unaddressed. Our emergency plumbing team quickly diagnoses and repairs both traditional and tankless water heaters, often restoring hot water service in one visit. Whether it’s a leaking tank, a gas supply problem, or an electrical failure, we are prepared to resolve the issue promptly.
Sewer Backups
Sewer backups are serious emergencies that pose health risks and property damage concerns. Our experienced technicians respond with the necessary equipment to clear mainline blockages, repair broken pipes, and eliminate root intrusions causing the problem. Once the blockage is cleared, we follow stringent cleaning and sanitization procedures to ensure your home stays safe and clean.
Frozen Pipe
Waterloo’s harsh winters can lead to frozen pipes, which can burst and create major plumbing emergencies. Our plumbers use careful thawing methods like heat tape, infrared lamps, and specialized equipment to restore water flow safely. We also assess your home’s vulnerable areas and implement preventative solutions to protect your pipes from future freezing issues.
