Which one do you need?
- Home Renovation Budget Calculator
- Build a renovation budget line by line — materials, labour, fixtures, permits and contingency — and track what is left against your ceiling as costs commit.
- Renovation Contingency Calculator
- Size a renovation contingency from the things that actually drive overruns — house age, concealed work, scope certainty and systems work — not a flat ten per cent.
- DIY vs Contractor Cost Calculator
- Compare a contractor quote against the true cost of doing it yourself — materials, waste, tools, permits and your own hours priced at a rate you choose.
- Contractor Quote Comparison Calculator
- Compare up to three contractor bids on the same scope by adding back exclusions and repricing allowances, so the cheapest headline meets the cheapest real total.
- Demolition Debris & Dumpster Size Calculator
- Estimate demolition debris volume and weight from what you are tearing out, size the dumpster, and see whether the tonnage cap binds before the box is full.
