Compare home contractor quotes against the same drawings, quantities, specifications and responsibilities before comparing the totals. A lower price can reflect a different scope, an unresolved allowance or an exclusion. Ask each contractor to explain the difference in writing rather than assuming price alone indicates quality.
Start with one project brief and a dated set of documents. Record any gaps that prevent a firm comparison. Our house construction budget and scope guide explains why floor-area rates need their assumptions stated.
Build a comparison sheet
| Comparison item | What to record | Question to resolve |
|---|---|---|
| Design basis | Drawing dates, revisions, dimensions and schedules used for pricing | Did all contractors price the same information? |
| Quantities and work | Areas, quantities, construction activities and retained items | Which work is missing, provisional or described differently? |
| Materials and finishes | Product, grade, size, finish system and installation scope | Do labels such as “standard” identify the actual specification? |
| Allowances and exclusions | Unresolved selections, excluded work and owner purchases | How will the final quantity or selection change the price? |
| Site and documentation | Access, temporary works, protection, disposal, professional services and approval tasks | Who is responsible and which charges are included? |
| Commercial terms | Taxes, validity, payment stages, changes, programme and closeout terms | What must be agreed before appointment? |
1. Resolve the scope first
Mark every difference in the documents and work descriptions. One proposal might include demolition, disposal and reinstatement while another prices only new installation. Renovation quotations also need to distinguish known repairs from conditions that cannot yet be assessed.
Ask for an explanation or revised proposal on a common basis. Do not add unlike headline totals together or treat an unpriced item as free.
2. Compare specifications rather than finish labels
“Tiles,” “paint” and “windows” can refer to different products and installation systems. Identify the actual material, dimensions, preparation, accessories and included work. Ask how substitutions are proposed and approved.
Use the finish-selection guide to prepare a schedule of choices. Keep owner-supplied fixtures and appliances visible in the comparison.
3. Separate the construction price from the full project budget
Check surveys, design services, authority charges, utility connections, site access, owner purchases, loose furniture and other required work. Determine which are included, separately quoted or arranged by the owner. Identify taxes and the quotation’s validity period.
A clearly stated exclusion is a decision to budget for, not automatically a hidden fee. An unclear responsibility needs clarification before the proposal becomes an agreed scope.
4. Review the programme and payment basis
Ask what the target programme assumes about access, design decisions, approvals, procurement and owner selections. Check the milestones and dependencies instead of choosing the shortest unsupported completion promise.
Payment arrangements depend on the agreed engagement. Record any advance, how progress is assessed, what supports each billing, how changes are handled and what is required at completion. The progress-billing guide helps prepare those questions.
5. Verify the team and project responsibilities
Review relevant completed-work references, the proposed team, current contractor-license particulars and the professionals responsible for the required design documents. Ask which reference visits or records can be shared with the appropriate client permission.
For Nillasca, see the business and project-verification information. Licensing and insurance answer different questions: read the contractor-insurance checklist and confirm the arrangements for the actual project rather than assuming every risk is covered.
What should you request before making a decision?
- A written response to each scope and specification difference.
- A list of unresolved allowances, exclusions and owner responsibilities.
- The documents and revisions on which the price is based.
- The validity, taxes, payment and variation terms.
- The proposed programme and its key dependencies.
- The responsibilities for inspections, completion checks and handover records.
Keep the contractor’s response with the proposal so the final comparison reflects the clarified work. Resolve substantial uncertainty before appointing a team; the most detailed-looking document can still contain important gaps.
