Begin with the outcome, not a product list
Describe the activity that needs to become easier. For example, getting from the car into the bathroom is a different scope from installing one threshold product. A clear objective helps identify which work is essential, which can be staged and which is optional.
Use a planning allowance carefully
The allowances on our pricing page are broad figures supplied for this website, not independently measured market averages. A complete accessible bathroom has an indicative allowance of $25,000 to $60,000 or more; broader home changes can exceed that. These figures are not a quote, an offer or a funding entitlement. The inspected site and agreed scope determine the price.
Understand the hidden construction
Moving plumbing, changing a floor level, opening a structural wall and dealing with existing defects can alter a quote substantially. Ask what the builder has inspected and what remains uncertain. An apparently similar finish may involve very different work beneath it.
Compare inclusions line by line
Check demolition, disposal, protection, waterproofing, plumbing, electrical work, fixtures, finishes and reinstatement. Look for allowances that are not fixed selections. Ask whether design, engineering, approvals and temporary facilities are included or separate. Confirm GST treatment and the contracting entity.
Plan for the household during the work
Losing the only bathroom is different from renovating a spare room. Discuss access, noise, services and any alternative arrangements needed. Do not assume temporary facilities or accommodation are included unless the quote says so.
Keep contingency separate from permission to spend
Ask the builder how unforeseen conditions and variations are handled. Agree how changes are documented and approved before they proceed. A contingency is a planning buffer, not an automatic authority to add work.
Get the next quote from a better brief
Prepare the address, desired changes, photos without private information, equipment details where relevant and any available professional scope. Ask for an assessment before relying on a final number. Where funding is involved, check the funder's quote requirements first.
