Compare the same scope, finish and handover, with unresolved items shown as allowances rather than hidden in the total.
Measure the work, not just the floor
Floor area describes the room. It does not describe every wall, ceiling, opening, bulkhead or return that needs board and finishing. An estimate request is clearer when it separates room dimensions from the surfaces being worked on.
- Note each affected room and approximate ceiling height.
- Separate walls, ceilings and small isolated repairs.
- Mark whether existing board remains, is already removed, or needs assessment.
- Identify stairwells, high areas, alcoves and difficult access.
The factors worth comparing
| Factor | Detail to include in the request |
|---|---|
| Starting condition | Open framing, sound existing board, damaged edges, previous patches or unknown concealed conditions. |
| Access & protection | Occupied rooms, furniture, stairs, elevator booking, loading and floor protection. |
| Surface & geometry | Wall and ceiling areas, corners, returns, openings and ceiling height. |
| Finish expectation | Texture, selected finish level, final paint sheen and strong side lighting. |
| Handover | Who supplies material, removes waste, primes, paints and completes the final cleanup. |
| Coordination | Other trades, access restrictions, required approvals and the desired completion window. |
Why a small patch is not a scaled-down room
A small repair still needs an agreed work area, preparation, a sound repair boundary and a finish that works with the surrounding surface. Ask whether the estimate includes only the patch or a wider area of finishing, primer and paint.
The number of visits and any minimum-job policy are contractor-specific. Have them stated in the estimate rather than assuming that a small hole means one brief visit.
Put two estimates beside each other
- Check that both describe the same surfaces and starting condition.
- Match the finish expectation and the point at which the work is handed over.
- Check materials, removal, disposal, protection and cleanup.
- Read exclusions and allowances, then ask how additional work is approved.
- Clarify applicable taxes, payment terms and what would trigger a revised estimate. Ask for separate allowances for unassessed damage, testing or approval work so a provisional sum is not mistaken for a fixed inclusion.
Allow for the checks between opening and finishing
Coquitlam’s inspection system lists stages against each permit, and the City warns that prematurely concealed work may need exposing. For a drywall estimate within a permitted renovation, identify the actual release points before comparing visits or closure dates. Ask whether any waiting, return visit or revised repair area is included or remains an allowance.

- List the building and plumbing records relevant to the affected surfaces.
- Separate boarding from finishing where a project-specific inspection comes between them.
- Ask who authorises extra work if a concealed condition changes the assessed boundary.
A few practical questions.
Can I compare estimates using a price per square foot?
Only when the measured area and inclusions mean the same thing. Ask whether the rate covers board area or floor area, labour or materials, removal, finish level and any ceiling work. Compare the complete written scope alongside the rate.
What information is most useful before a site visit?
The affected rooms, approximate dimensions, starting condition, desired finish, access restrictions and what other trades are doing. Be clear about what is still unknown so the contractor can identify the next assessment step.
