A solid Calgary renovation contract spells out the full scope of work, a fixed price, a payment schedule tied to milestones, a written change-order process, permit responsibility, warranty terms and proof of insurance and WCB coverage. If any of those are vague or missing, that is where budgets and timelines tend to go sideways. We work from fixed-price quotes with a clearly defined scope, so you know your number before work begins and Jonathan Edwards stays accountable throughout.

The Contract Is Your Protection

A renovation contract isn’t just a formality — it’s the document that protects you if things go wrong, defines what “done” means, and sets expectations for both sides. Here’s what every Calgary homeowner’s renovation contract should include.

Must-Have Contract Elements

1. Detailed Scope of Work

Not “kitchen renovation” — it should list every major element: specific cabinet manufacturer and model, countertop material and thickness, tile brand and code, fixture model numbers, electrical scope, plumbing scope, what is excluded.

2. Contract Price and Allowances

Fixed price (better for homeowner) or cost-plus with a cap. If there are “allowances” (e.g., “$3,000 tile allowance”), understand that going over the allowance is a change order — it costs you more.

3. Payment Schedule

Tied to milestones, not to calendar dates. Example:

10% on signing
25% on demo completion
25% on rough-in inspections passed
25% on drywall and flooring complete
15% on substantial completion

Never pay more than the work completed to date.

4. Start and Completion Dates

With a penalty clause for late completion (or at minimum an agreed process for delays and communication).

5. Change Order Process

All changes to scope must be in writing, signed by both parties, before work begins. Change orders that aren’t in writing are the source of most renovation disputes in Calgary.

6. Permit Responsibility

Clearly state that the contractor is responsible for pulling all required permits and scheduling all inspections.

7. Warranty

Minimum one year on labour for most projects. Alberta’s New Home Buyer Protection Act covers new builds (1 year labour, 2 years mechanical, 5 years building envelope, 10 years structural). For renovations, negotiate in writing.

8. Lien Waiver Clause

Protect yourself from subcontractors and suppliers placing liens on your property if the GC doesn’t pay them. Request statutory declarations from the GC confirming all subs and suppliers are paid at each payment milestone.

9. Insurance Requirements

State the minimum liability insurance ($2M) and WCB coverage required, and that certificates must be provided before work starts.

10. Dispute Resolution

How will disputes be handled? Mediation first (cheaper than court). Which jurisdiction? Alberta law.

Red Flag Contract Clauses

“All payments non-refundable” — walk away

Payment schedule requiring 50%+ upfront

Frequently asked questions

What should a renovation contract include in Calgary?

At minimum it should define the scope of work, the price, a milestone-based payment schedule, how changes are handled, who pulls permits, warranty terms, and proof of insurance and WCB coverage. Anything left vague is a risk to your budget and timeline.

Should I pay a large deposit up front?

A reasonable, scheduled deposit is normal, but a demand for a large share of the total before work starts is a warning sign. We tie payments to defined milestones so money follows progress.

How are changes to the project handled?

Through a written change order that documents the added scope and its cost before the work happens, so nothing is a surprise on the final invoice. This keeps a fixed-price quote honest even when plans evolve.

Why does a fixed-price quote protect me?

A fixed-price quote locks your number to a defined scope so you are not exposed to open-ended hourly billing or per-square-foot guessing. With Jonathan Edwards involved on every job, you also have one accountable point of contact if questions come up.
