Services
Drain Cleaning
Our advanced drain cleaning services eliminate clogs and buildup in residential and commercial plumbing systems. Using high-pressure water jetting and motorized augers, we restore optimal flow to drains, sewer lines, and piping. Our technicians identify root causes like grease accumulation or tree root intrusion, providing lasting solutions while minimizing property disruption.
Water Heater Services
We specialize in water heater installation, repair, and maintenance for traditional tank and tankless systems. Our certified technicians handle Bradford White and Noritz models, offering energy-efficient upgrades with potential tax credits. Services include tank replacement, anode rod maintenance, and thermal expansion tank installation to prevent pressure damage.
Gas Line Repair
Our licensed plumbers install and repair gas lines for residential appliances including fireplaces, barbecues, and water heaters. We perform pressure testing and leak detection to ensure safety compliance. Services include replacing corroded lines, installing new gas mains, and connecting appliances with CSA-certified fittings for propane and natural gas systems.
Trenchless Drain Services
Trenchless technology allows us to repair damaged sewer lines without excavation. Using cured-in-place pipe (CIPP) lining, we create durable, jointless replacements inside existing pipes. This method preserves landscaping and reduces repair time by up to 50% compared to traditional dig-and-replace methods while maintaining structural integrity for decades.
Toilet & Faucet Repair
We service all toilet and faucet brands, specializing in Kohler, Gerber, Wolverine Brass, and Premier models. Our repairs address leaks, running toilets, and hard water damage using manufacturer-certified parts. We install water-efficient fixtures that reduce consumption while maintaining performance, with ceramic disc technology for leak-free operation.
