Professional Plumber in Coquitlam, BC

Coquitlam is one of Metro Vancouver's fastest-growing cities, with development stretching from established neighbourhoods along the Lougheed corridor up through Westwood Plateau and into the newer communities on Burke Mountain. This blend of housing from different eras means Coquitlam properties face a wide range of plumbing demands. Homes built in the 1960s and 1970s near Austin Heights and Maillardville contend with aging pipe systems and outdated drainage infrastructure, while brand-new construction on Burke Mountain requires careful drainage engineering to manage the heavy rainfall that flows down from the surrounding mountains. HYDROPRO PLUMBING & WATER LTD serves all of Coquitlam with licensed, experienced plumbers who understand the full spectrum of residential and commercial plumbing needs in this diverse city.

Coquitlam's proximity to the Coast Mountains means it receives substantially more rainfall than communities further south in the Fraser Valley. That rainfall, combined with the city's terrain that rises from the Coquitlam River valley to elevations above 350 metres on Burke Mountain, creates serious drainage challenges for property owners. Water that saturates the hillside soils must go somewhere, and without proper drainage systems in place, it ends up against foundations, beneath basement slabs, and pooling in yards. HYDROPRO specializes in the drainage solutions Coquitlam homeowners need to protect their properties from water intrusion.

Common Plumbing Issues in Coquitlam

Coquitlam's varied terrain and housing mix give rise to plumbing problems that differ significantly from one neighbourhood to the next. Our plumbers regularly encounter the following issues across the city.

• Inadequate drainage on hillside properties: Many homes on Burke Mountain and Westwood Plateau were built on lots carved into sloped terrain. If the original drainage design was insufficient or if the system has deteriorated, surface runoff and subsurface water flow can overwhelm perimeter drains and flood basements. Properties at the base of slopes are especially vulnerable during prolonged fall and winter rain events.
• Foundation waterproofing failures: Coquitlam homes on hillside lots experience constant hydrostatic pressure against their below-grade walls. When the original waterproofing membrane degrades or perimeter drains become clogged with silt and roots, water finds its way through concrete cracks and construction joints. Left unaddressed, this leads to structural damage, mould, and loss of livable basement space.
• Aging pipes in established Coquitlam neighbourhoods: The older areas of Coquitlam, including Ranch Park, Central Coquitlam, and parts of Maillardville, have homes with galvanized water lines and clay or cast iron sewer laterals that have reached or exceeded their expected lifespan. These pipes corrode, crack, and attract root intrusion, resulting in reduced water pressure, discoloured water, and recurring drain blockages.
• New construction drainage deficiencies: Even recently built homes in Coquitlam's newer subdivisions can experience drainage problems if the lot grading shifts during settlement or if builder-installed drainage systems were designed to minimum specifications. Retaining walls, compacted fill soils, and altered natural drainage patterns on developed mountainside lots all contribute to water management challenges.
• Driveway and walkway damage from water flow: Uncontrolled water runoff on Coquitlam's sloped properties erodes soil beneath concrete driveways, pathways, and patios, causing cracking, settling, and trip hazards. The underlying plumbing issue, whether it is a failed catch basin, blocked drain line, or absent surface drainage, must be resolved before concrete repairs can be effective.

Plumbing Services Available in Coquitlam

HYDROPRO provides Coquitlam homeowners with targeted plumbing solutions that address the root causes of water problems rather than treating symptoms. Our approach combines thorough assessment with proven repair methods.

Effective drainage installation is the single most important plumbing investment for many Coquitlam properties. HYDROPRO designs perimeter drainage systems, curtain drains, and surface drainage networks that account for the specific grade, soil composition, and water flow patterns of your lot. We install heavy-duty perforated pipe, proper filter fabric, and clean drainage rock to create systems built to perform reliably through decades of Coquitlam's heavy rainfall seasons.

When water intrusion has already caused damage to basement walls or concrete slabs, our foundation repair services restore structural integrity and stop future moisture penetration. We excavate along affected foundation walls, apply commercial-grade waterproofing membranes, and replace failed drain tile before backfilling with proper drainage aggregate. For Coquitlam homes on steep lots, this work is essential to preserving the home's value and livability.

Aging sewer and water lines in Coquitlam's established neighbourhoods benefit from our trenchless pipe replacement technology. This method allows us to install a new pipe inside the existing damaged line without excavating across your yard, driveway, or landscaping. Trenchless replacement is especially advantageous on Coquitlam properties with retaining walls, mature gardens, and finished hardscaping that would be costly to restore after traditional open-trench excavation.

After major drainage or foundation work, HYDROPRO's concrete services restore driveways, walkways, patios, and retaining wall footings to proper condition. We pour and finish concrete to match existing surfaces wherever possible, ensuring that the completed project looks professional and functions correctly. Proper grading of new concrete surfaces is critical on Coquitlam's sloped lots to direct water away from the home rather than toward it.
