Lead & Galvanized Water Service Replacement in Ajax

Open-cut excavation (full trench, traditional method): $7,000–$14,000 depending on length, surface materials, and depth. Pipe-bursting trenchless: $5,000–$9,000 (faster, less surface restoration). Pull-through trenchless for short straight runs: $4,500–$8,000. Ajax Water provides free city-side replacement under the Ajax Lead Service Replacement Program for eligible pre-1955 homes — homeowners pay only for the private-side from property line to home. Cost factors: distance, surface (sod easy, interlock or asphalt costlier), depth, soil.

Visual at the meter: lead is dull silver-grey, soft (a thumbnail can scratch it), often with a 'wipe joint' swelling at junctions; galvanized is silver-grey but harder, magnetic (stick a fridge magnet — galvanized is magnetic, lead and copper are not); copper is reddish-orange. Free Ajax Public Health water test kit (call 311) confirms whether lead is leaching into your tap water. Ajax Water can sometimes confirm city-side material from records (call 311). Or hire a licensed plumber for a $200–$400 inspection.

Ajax Water replaces the city-side portion of the lead service line (from water main to property line) at NO COST to the homeowner under the Priority Lead Water Service Replacement Program. Typical city-side cost would be $3,000–$6,000 if the homeowner had to pay — making this one of North America's most generous lead-replacement programs. Eligibility: confirmed lead service on Ajax Water records, application submitted, pre-1955 priority neighborhood. RenoHouse can submit the application on the homeowner's behalf. Coordination with private-side replacement timing is critical so there is no extended water-service disruption.

Health Canada's Maximum Acceptable Concentration (MAC) for lead in drinking water is 0.005 mg/L (5 µg/L) — tightened from 0.010 mg/L (10 µg/L) in 2019 in line with World Health Organization guidance. Lead exposure is especially harmful for infants, children under 6, and pregnant women — affecting cognitive development at very low levels. The 2019 tightening put many more Ajax pre-1955 homes over the new limit. Ajax Public Health offers free lead water test kits to confirm exposure.

Open-cut excavation (traditional trench): $7,000–$14,000 — best when the existing surface is sod (easily restored), when there are obstructions or significant elevation changes, or when the line has been extended/repaired multiple times. Pipe-bursting trenchless: $5,000–$9,000 — best when the existing surface is asphalt driveway, interlock, or mature landscaping (much less restoration cost), and when the existing line is reasonably straight. Pull-through trenchless: $4,500–$8,000 for short straight runs. Our licensed plumber assesses at the site visit and recommends the method.

City-side (water main to property line) is replaced by Ajax Water under the Lead Service Replacement Program — at no cost to the homeowner. RenoHouse coordinates with Ajax Water on scheduling so the city-side and private-side are done the same day or within a short window. Without coordination, a new private-side line connects to old lead at the property line — defeating the health benefit. We submit the Ajax Water application on the homeowner's behalf, manage scheduling, and deliver the private-side replacement plus all surface restoration.

Open-cut excavation: 3–5 days from start of digging to restoration sign-off. Trenchless (pipe-bursting or pull-through): 1–2 days. Permit and Ajax Water coordination: 2–6 weeks before excavation. Total project clock from contract signing to completion: 4–10 weeks. Water service is interrupted for 4–8 hours during the actual replacement (we coordinate timing with the homeowner's schedule).

No. Water service replacement requires a master plumber licensed by the City of Ajax for water service work — they pull the Ajax Water Service Connection permit, sign off on the connection, and perform the inspection. RenoHouse does NOT have a Ajax-Water-licensed master plumber on staff. We coordinate certified subcontractor partners with the necessary licensing and excavation equipment. RenoHouse holds the contract, manages the Ajax Water permit and program application, coordinates the schedule, and delivers all surface restoration (concrete, asphalt, sod, interlock). The licensed master plumber signs off on the water service.

Yes — restoration is included in the project scope. Sod and topsoil restoration: typical. Asphalt driveway patching: included for trench area; full driveway resurfacing is optional add-on $2,500–$6,000. Interlock pavers: lifted before excavation, reset after with new sand and polymeric joint sand; some pavers may break and require replacement (sourced to match). Concrete sidewalk or driveway: cut and re-poured — match-finish to existing. We document pre-existing conditions with photos before excavation. Settling typically requires a follow-up topsoil top-up at 6–12 months.

Yes — and we recommend it. The kitchen and bathroom rough-in stage already involves plumbing trades, permit fees, and inspection visits — adding the water service replacement saves cost and reduces disruption. The replacement requires excavation outside the home, so it doesn't interrupt the interior renovation work. We typically schedule the service-line replacement during the demo or rough-in phase, restore the interior plumbing entry, and continue the renovation.

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.
