Read guide →When To Replace Water Heater
Replace your water heater when it is more than 10–12 years old AND showing symptoms: rusty water, rumbling noises, inconsistent heat, or water pooling around the base. In Toronto, hard water (18–25 GPG) shortens typical tank life by 2–3 years compared to national averages. Replacement costs $1,400–$3,200 for standard gas tanks installed.
Read guide →Frozen Pipes Prevention Toronto
Pipes freeze in Toronto when exposed sections reach -6°C or below. The highest-risk locations are exterior wall cavities in pre-1980 bungalows, garage water lines, under-sink cabinet pipes on exterior walls, and crawl spaces. Prevention is free; burst pipe repair costs $400–$2,500. The critical window in Toronto is January through mid-February during cold snaps below -15°C.
Read guide →Basement Flooding Prevention Toronto
Toronto experiences over 200 basement flood insurance claims per major storm event. The three most effective prevention measures are: backwater valve installation ($800–$2,500, subsidized up to $1,750 by the City), sump pump installation or upgrade ($400–$1,500, subsidized up to $1,750), and downspout disconnection ($100–$400, subsidized up to $400). Together these qualify for up to $3,400 in City of Toronto rebates.
Read guide →Lead Pipe Replacement Toronto
Toronto's Lead Pipe Replacement Program replaces the city-owned portion of lead water service lines for free. Homeowners pay only for the private portion (foundation to property line), typically $1,500–$3,500. Coordinating both replacements at the same time saves $1,000–$2,500 in excavation by opening the ground only once. Homes built before 1955 in Toronto are the most likely to have lead service lines.
Read guide →Backwater Valve Installation Toronto
Backwater valve installation in Toronto costs $1,000–$2,500 installed and requires a City of Toronto building permit. The City subsidizes up to $1,750 through the Basement Flooding Protection Subsidy, bringing net homeowner cost to $0–$750 for most installations. Work must be done by a licensed plumber. Permit inspection is required before backfilling concrete.
Read guide →Sump Pump Maintenance Guide
Sump pumps protect Toronto basements from groundwater flooding during spring snowmelt and heavy rain. A 15-minute annual inspection can prevent a $400–$1,500 pump failure that could allow $5,000–$30,000 in water damage. Key steps: test the pump annually before spring season, check the discharge line, inspect the float switch, and ensure the battery backup is charged. Sump pumps last 7–10 years in Toronto.

Polybutylene (Poly-B) pipes were installed in Toronto-area homes from approximately 1978 to 1995 and are now known to fail without warning — typically at fittings, but sometimes mid-pipe. Replacement cost is $6,000–$14,000 for a typical 1,800–2,500 sq ft GTA home. Home insurers are increasingly refusing to cover Poly-B homes. Affected areas include large portions of Brampton, Vaughan, Mississauga, Newmarket, and Milton.

To choose a trustworthy plumber in Toronto: verify their Ontario Certificate of Qualification (306A license), confirm they are covered by WSIB and $2M liability insurance, ask for a written flat-rate quote before work begins, and check Google reviews for recency. Avoid any plumber who will not provide licensing details or written quotes. Expect to pay $120–$180/hour or flat rates starting at $150 for common repairs.
