A renovation estimate helps identify major expenses before work begins. Use the steps below for an initial estimate, then update it using actual measurements and current local prices. The final cost depends on the room’s condition, location, chosen materials, and complexity of the work.
1. Measure the room
Record the room’s length, width, and height. Measure windows, doors, and areas that do not need finishing separately. For complex shapes, divide the room into simpler sections.
2. Group expenses by category
- Materials: flooring, paint, filler, primer, and other supplies.
- Labor: surface preparation, installation, and finishing.
- Additional costs: delivery, equipment rental, and waste removal.
- Contingency: set aside funds for unexpected work and price changes.
3. Check material coverage rates
Material usage depends on the manufacturer, surface, and application method. Check the package instructions and do not assume one rate applies to every material.
4. Compare quotes
Compare not only the package price, but also coverage, usage rate, delivery, warranty, and return options for unused material. Ask contractors to clarify the scope of work and what is included in their price.
5. Recalculate before ordering
Update the estimate after checking actual dimensions, current prices, and delivery terms. The KiwiLab Renovation Calculator can help organize an initial estimate.
Before you start
- Check measurements and room geometry.
- Confirm current material prices and coverage rates.
- Ask for a clear breakdown of labor costs.
