What the quote should say
- Each crack and its length
- Whether the joint is re-taped or only filled
- How many coats of compound, and sanding
- Primer and paint: included or not
- If the contractor thinks framing or the structure is involved, that they say so in writing before work starts
Permits
Patching holes and cracks is not named on the City of Ottawa's list of work that needs a building permit, or on its list of work that does not. If you are unsure about your job, ask the City. Adding or removing walls and structural repairs are on the City's permit list, and the drywall on that kind of job is part of that permit.
Quick answers
Why is the per-crack range so wide?
The two published sources priced crack repair at different levels, so this page shows the full span, from the lower source's low end to the higher source's high end. Your quote should say how long each crack is and what is done to it.
Who should look at a crack that comes back?
A drywall contractor can re-tape a joint. If you are worried about the framing or the structure, ask a professional engineer; the City's flood-repair FAQ recommends one wherever structural damage is suspected.
