Should I get a written contract for a parging job and what key terms should it include in Ontario?

Yes, you absolutely should get a written contract for any parging job in Ontario, regardless of size. A written contract protects both you and the contractor, clarifies expectations, and provides legal recourse if issues arise. Ontario's Consumer Protection Act requires written contracts for home improvement services over $50, and even smaller parging repairs typically exceed this threshold.

Essential contract terms for parging work should include the contractor's full business name, address, and contact information, plus their WSIB clearance number (mandatory in Ontario). The scope of work must be detailed — specify exactly which foundation walls will be parged, whether old parging will be removed, what surface preparation is included, and the type of parging material (traditional Portland cement, polymer-modified, or specific brand names). Include square footage measurements and any additional work like caulking, minor crack repair, or cleanup.

Material specifications matter significantly in the GTA's harsh freeze-thaw climate. The contract should specify whether bonding agent will be applied (it must be), the number of coats (typically two for durability), cure time before painting (minimum 28 days), and any mesh reinforcement for thick applications. For polymer-modified parging, specify the brand and product line since performance varies dramatically between manufacturers. Weather protection provisions are crucial — the contract should state that work will not proceed if temperatures are below 5°C or if rain is forecast within 24 hours of application.

Pricing and payment terms should be crystal clear. Total project cost, payment schedule (never pay more than 10% upfront under Ontario law), and what triggers each payment milestone. Include provisions for change orders if additional work is discovered — many GTA foundation walls reveal hidden damage once old parging is removed. Specify who pays for disposal of old parging material and whether cleanup of the work area is included.

Timeline and warranty provisions protect your investment. Include start and completion dates with weather delay allowances (common in GTA spring and fall). A reputable contractor should warranty their parging work for minimum 2-3 years against delamination, cracking, or workmanship defects. The warranty should specify what's covered, what's excluded (damage from foundation movement, impact damage, or homeowner modifications), and the process for warranty claims.

WSIB and insurance requirements are legally mandatory in Ontario. The contract must confirm the contractor carries valid WSIB coverage and general liability insurance minimum $2 million. Request certificates before work begins — you can be held personally liable for workplace injuries if you hire an uninsured contractor. Include a clause requiring the contractor to obtain any necessary permits and comply with Ontario Building Code requirements.

Cancellation rights under Ontario law give you three business days to cancel any home improvement contract over $50 without penalty. The contract must include this cancellation clause and provide the proper cancellation form. For larger projects, consider adding a clause allowing cancellation for cause (contractor fails to show up, uses wrong materials, or performs substandard work) with appropriate notice periods.

Special considerations for GTA parging contracts should address seasonal timing restrictions, salt damage protection if your foundation is near driveways or streets, and coordination with any planned landscaping or drainage work. Include provisions for protecting existing plants, walkways, and utilities during the work. For heritage homes in established Toronto neighbourhoods, specify that appropriate mortar types will be used — Portland cement mortar can damage soft heritage brick through spalling.

Red flags to avoid include contractors who refuse to provide written contracts, demand large upfront payments, quote prices significantly below market rates ($8-18 per square foot for quality parging in the GTA), or cannot provide WSIB clearance certificates. Door-to-door contractors and those pressuring for immediate decisions should be avoided entirely.

A well-written contract typically runs 3-5 pages for parging work and should be reviewed carefully before signing. When in doubt, have a lawyer review contracts for larger projects over $5,000. Remember that the cheapest quote often becomes the most expensive when poor workmanship requires complete re-application within 2-3 years.
