A strong workmanship warranty is one of the clearest signals that separates professional Ottawa contractors from fly-by-night operators. Anyone can promise quality during the sales pitch; only a serious business puts a multi-year warranty in writing and stands behind it. This 2026 guide explains what warranty terms are industry-standard, how Ontario's Tarion program fits in for new builds, the typical defects that surface year by year in Ottawa's climate, and exactly how to enforce a warranty claim when a contractor stalls. Understanding warranties before you sign — and getting every promise i...
Know the benchmarks so you can judge what a contractor offers. Renovation contractors should provide at least a one-year workmanship warranty (the Ontario industry norm), and reputable Ottawa firms commonly offer two to three years. New-home builds fall under mandatory Tarion coverage: one year on all defects, two years on water penetration plus plumbing, electrical, and HVAC, and seven years on major structural defects. Trade-specific warranties layer on top: roofing carries 25-50 years (manufa...
These are two different things and you need both. The manufacturer warranty covers the product itself — shingles, windows, the furnace — and is passed through to you. The workmanship warranty covers the contractor's installation. Many failures are installation errors (improper flashing, a leaking va...
Use warranty length as a screening tool when comparing Ottawa contractors. An operator offering only a 30- or 90-day workmanship warranty is quietly telling you how long they expect to be reachable; a firm offering two to three years is betting their own money that the work will hold up. During the ...
Verbal warranty promises evaporate the moment a problem appears, so insist everything is documented in the contract. Require: (1) all workmanship covered for a stated period from substantial completion; (2) all materials supplied by the contractor covered by their manufacturer warranties, passed through to you; (3) a defined coverage period for latent defects — problems not visible at completion; (4) a clear warranty-claim process stating how to notify, the response time, and the repair window; ...
Before signing, confirm the warranty clause states all of the following: the workmanship period and its start date (substantial completion), pass-through of manufacturer warranties on supplied materials, a latent-defect coverage period, the notification method and contractor response time, the repai...
Tarion is Ontario's new-home warranty program, and it applies to new home construction, new condos, and major renovations that amount to substantial reconstruction — not to typical renovations. If you are buying or building new in an Ottawa development, your builder must be enrolled with the Home Construction Regulatory Authority and your home registered with Tarion. Coverage runs on the 1/2/7-year tiers above, and claims follow a defined statutory process with set submission windows (notably a ...
Defects surface on a predictable timeline, and Ottawa's freeze-thaw cycles accelerate some of them. Year one: caulking failures, paint touch-ups, drywall cracks at seams, door and window adjustment, loose hardware, and minor settlement cracks. Years two to three: tile grout cracking, flooring transition issues, and mid-grade fixture failures. Year five and beyond: roofing flashing problems, exterior caulking and sealant failures driven by repeated freeze-thaw expansion. Year seven and beyond: ma...
Repeated freezing and thawing is hard on buildings. Water gets into hairline gaps, freezes, expands, and widens them, which is why exterior caulking, roof flashings, masonry mortar, and deck fasteners are common multi-year warranty issues in Ottawa. When evaluating a warranty, pay special attention ...
Follow a disciplined process and most claims resolve quickly. (1) Document the defect with dated photos and written notes. (2) Notify the contractor in writing — email is fine and preserves a record. (3) Reference the specific warranty clause in your contract. (4) Request a response within the contract-specified timeframe, typically five business days. (5) If the contractor delays, send a formal cure notice with a firm deadline. (6) If still unresolved, escalate. Keep every message in one thread...
If a contractor stonewalls, your escalation options are: a formal written cure notice, small claims court for amounts under $35,000, a complaint to the Better Business Bureau, a Tarion claim for new builds only, or formal litigation for larger amounts. Most warranty disputes settle at the cure-notic...
Set a calendar reminder for two months before each warranty period expires and do a deliberate inspection: check caulking, drywall seams, doors and windows, grout, exterior sealants, and roof flashings. Any defect found inside the period is the contractor's responsibility; the same defect found a mo...
Manage expectations by knowing the standard exclusions. Workmanship warranties do not cover normal wear and tear, damage you cause, lack of maintenance (for example, failing to clear gutters or reseal a deck), acts of God, settling within normal tolerances, or work altered by another trade after completion. Homeowner insurance generally will not fill the gap either: it covers sudden and accidental events, not defective workmanship. This is exactly why a contractor's workmanship warranty, valid W...
The industry minimum is one year on workmanship, while reputable Ottawa firms offer two to three years. Tarion covers new-home construction on 1/2/7-year tiers. Manufacturer warranties on materials are separate, typically 5-50 years, and are passed through from the contractor.
No, not for typical renovations. Tarion covers new home and condo construction and major renovations that amount to substantial reconstruction. For a standard kitchen, bathroom, or basement renovation you rely on the contractor's workmanship warranty plus the manufacturer warranties on materials.
Manufacturer coverage on shingles runs 25-50 years (limited), while installer workmanship coverage runs 2-10 years depending on the contractor. Many roof problems are installation failures — improper flashing, underlay, or ventilation — so the installer's workmanship warranty matters as much as the shingle warranty.
Document everything in writing, then send a formal cure notice. If unresolved, escalate to small claims court (under $35K), a BBB complaint, a Tarion claim (new builds only), or litigation. Most disputes settle at the cure-notice stage once the contractor sees a documented refusal will hurt their reputation. Keep a single dated email thread documenting the defect, your notice, and the deadline, since a clear written record is your strongest evidence if the claim ends up in small claims court.
Generally no. Homeowner insurance covers sudden and accidental events, not defective workmanship. That is why the contractor's warranty, WSIB coverage, and $2M liability insurance matter so much. If the contractor closes shop, manufacturer warranties on materials are often your only remaining recourse.
