Why Hire a Certified Plumber in Mississauga?

When it comes to protecting your home or business from plumbing issues, hiring a certified plumber in Mississauga is a decision you won’t regret. Certification isn’t just a title—it’s a guarantee of professionalism, compliance, and peace of mind.

Certified plumbers undergo rigorous training and testing to ensure they meet provincial and local standards. This licensing ensures that your plumbing work is performed safely, efficiently, and in compliance with building codes. It also means the contractor is insured, bonded, and accountable to regulatory bodies.

By choosing a certified professional, you’re not just hiring someone with tools—you’re investing in long-term protection for your property. From compliance with permit requirements to thorough documentation and clean execution, a certified plumber handles every detail with care.

Delex Plumbing is proud to offer certified plumbing services across Mississauga, delivering trust, quality, and reliability with every visit. Our licensed professionals follow all WSIB, municipal, and provincial regulations to ensure the safety of your home and the quality of your results.

Moreover, certified plumbers like ours stay updated on the latest plumbing codes and technologies. This ensures that every installation or repair meets current safety and efficiency standards. You avoid unnecessary rework, failed inspections, and added costs by starting with certified expertise from day one.

Certified Plumbing Services We Offer

Whether you’re dealing with an emergency or planning an upgrade, our certified plumbing team is here to help. Here are just some of the core services we provide across Mississauga:

Emergency Repairs (Fully Licensed Response)

Plumbing emergencies can cause damage if not addressed immediately. Our team provides 24/7 emergency services with a certified plumber on every call. Whether it's a burst pipe, water main issue, or flooding, you'll get immediate help from a qualified expert. We utilize advanced diagnostic tools, high-quality parts, and specialized training to resolve urgent problems quickly and safely, all while protecting your property and ensuring compliance with local codes. We also advise homeowners and businesses on temporary measures to minimize damage until we arrive. Our rapid-response technicians come equipped with everything needed to perform most repairs on the first visit—reducing downtime and stress.

Fixture Installation & Replacements

Certified fixture installation is key to preventing leaks, inefficiencies, and safety issues. We handle toilets, faucets, showers, and sinks with precision, ensuring secure connections, clean finishes, and full compliance with plumbing standards. Our certified plumbers can recommend water-efficient fixtures and install them with attention to pressure, drain performance, and longevity. Whether you're upgrading a powder room or remodelling an entire bathroom, our licensed team ensures everything functions flawlessly. We work with leading fixture brands and can also assist with warranty documentation after installation.

Pipe Inspection & Leak Repair

Undetected leaks can lead to mould, structural damage, and high water bills. Our certified leak detection service utilizes video inspection and pressure testing to pinpoint issues without causing unnecessary damage to your walls or floors. Once located, we repair the leak using proven, code-compliant methods. Whether it's copper, PEX, or PVC piping, our team knows the proper fix and installs it cleanly and efficiently. We also offer comprehensive repiping services for homes with aging plumbing systems, where recurring leaks are becoming a significant issue. All replacements are documented and performed under strict quality control standards to ensure reliability for years to come.

Hot Water System Setup & Maintenance

Installing or repairing a water heater should always be handled by certified professionals. We provide expert hot water system services, including the installation of your tankless and traditional water heaters. All setups include pressure safety checks, ventilation assessments, and post-installation inspections. Routine maintenance is also available to extend the life of your system and optimize energy use. Our certified technicians will size your water heater according to your home's occupancy and usage patterns, ensuring you always have hot water available. We also dispose of old units responsibly and ensure the replacement meets all environmental and safety standards.

Drain Clearing & Backflow Prevention

Drain issues and backflow concerns require a certified touch. We offer licensed drain clearing, hydro jetting, and backflow prevention device installation to ensure your water supply stays clean and uncontaminated. Backflow systems are mandatory for specific properties and plumbing layouts—our certified team will assess your needs and recommend the right preventative solution. Additionally, we offer annual testing for existing backflow prevention devices, ensuring compliance with city regulations and providing peace of mind for homeowners and business owners.

Basement Plumbing & Flood Protection

Basement plumbing is complex and highly vulnerable to damage during storms and heavy rainfall. We install and maintain sump pumps, backwater valves, floor drains, and other flood protection systems with full certification. We also provide rough-ins for basement bathrooms, laundry plumbing, and complete below-grade systems for new builds or renovations. Our basement services are especially popular in flood-prone areas of Mississauga. We assess drainage slopes, foundation penetration points, and regional stormwater trends to develop customized protection plans tailored to each site's specific needs and requirements
