Home renovations are exciting until the final bill arrives and it’s much higher than expected. Budget overruns are one of the most common complaints among homeowners in Vancouver and the Lower Mainland. While some surprises are unavoidable, the pricing model your contractor uses often has the biggest impact on whether you stay on budget.
The Three Most Common Pricing Models
- Cost Plus
The contractor charges you for the actual cost of labour and materials, then adds a markup (usually 15–25%). Because costs can fluctuate throughout the project, there’s no guaranteed final price.
- Time & Materials (T&M)
Labour is billed hourly, and materials are charged separately. The total cost depends on how long the project takes and how much is spent on materials and subcontractors.
- Fixed Price (Lump Sum)
The contractor provides a detailed quote for the entire project scope. The price is locked in before work begins and only changes if the homeowner approves additional work in writing.
Why Budget Overruns Usually Happen
With Cost Plus and Time & Materials contracts, there is very little incentive for the contractor to finish the job quickly or control costs. Any delays, material price increases, or unexpected issues are passed directly to the homeowner.
In contrast, a Fixed Price contract shifts the responsibility to the contractor. They must manage the schedule, labour, and costs efficiently. This model significantly reduces the risk of nasty surprises for homeowners.
While change orders can still occur during a renovation, they should always be documented, priced, and approved in writing before the work begins.

How to Protect Your Renovation Budget
Here’s how smart homeowners in Vancouver avoid costly overruns:
- Ask for a detailed, itemized fixed-price proposal that clearly defines the full scope of work.
- Confirm whether the quote is a firm fixed price or just an estimate.
- Ensure all changes require a written change order with cost and timeline impact.
- Inquire about how the contractor plans to schedule trades and materials to prevent delays.
- Request a final walkthrough before final payment to confirm everything was completed as agreed.
The Bottom Line
A low initial estimate might look attractive, but it often leads to higher final costs. A well-prepared fixed-price proposal gives you clarity, control, and peace of mind.
Pro Tip: Before signing with any contractor, ask this one important question: “Is this a fixed price, or just an estimate?”
