Markham's diverse housing ages create varied plumbing needs.

Our Markham plumbing team diagnoses and solves issues across all eras and neighborhoods.
Basement waterproofing is an important concern in parts of Markham where the Rouge River watershed affects ground water levels. We install sump pumps, backwater valves, and drainage solutions in homes across Markham, protecting basements from flooding and moisture damage.
While newer suburban homes have modern plumbing systems, common issues include builder-grade fixtures that fail prematurely, improperly sloped drain lines, and unfinished basement rough-ins that need professional connection. Many homeowners also upgrade basic fixtures to higher-quality faucets, toilets, and water heaters.
Average hot water tank repair & replacement cost in Markham and the GTA: $150–$800 per job, depending on complexity — simple faucet installs start lower, while water heater replacements and re-piping are at the higher end.

Frequently Asked Questions About Hot Water Tank Repair & Replacement in Markham
If your tank is less than eight years old and experiencing minor issues like a faulty thermostat or heating element, repair is usually the better choice. If the tank is leaking from the bottom, over ten years old, or producing rusty water, replacement is typically more cost-effective. RenoHouse provides honest assessments.
A standard hot water tank typically lasts eight to twelve years with regular maintenance. Factors like water quality, usage patterns, and maintenance frequency affect lifespan. RenoHouse can inspect your tank and advise on its remaining useful life.
In many cases, yes. RenoHouse stocks common tank sizes and can often complete same-day replacement when your hot water tank fails unexpectedly. Call us at 289-212-2345 for availability in your area.
Tank size depends on your household size and hot water usage. A two-to-three person household typically needs a forty to fifty gallon tank, while larger families may require sixty to seventy-five gallons. RenoHouse helps you choose the right size during your consultation.
Many Markham homeowners save significantly by purchasing their own hot water tank rather than renting. While the upfront cost is higher, you avoid ongoing monthly rental fees and often get a better quality unit. RenoHouse can help you compare the options.
Yes, RenoHouse provides a workmanship warranty on all hot water tank installations. Tank manufacturers typically offer six to twelve year product warranties depending on the model. We ensure all installations meet Ontario codes.
Builder-grade fixtures often use lower-quality internal components that fail within 5–10 years. Common issues include leaky faucets, running toilets, and water heater failures. Upgrading to quality fixtures from brands like Moen, Delta, or Kohler provides lasting performance and better water efficiency.
Most newer suburban homes come with a capped plumbing rough-in in the basement. Finishing this into a full bathroom adds significant living space and resale value — typically $15,000–$25,000 in home value for a $8,000–$15,000 investment. We handle everything from connecting the rough-in to the finished bathroom.
For suburban families with higher hot water demand, tankless water heaters provide unlimited hot water, reduce energy costs by 20–30%, and last 20+ years vs. 10–12 for tank units. They're especially popular in newer homes where the gas line infrastructure already supports them.
