Ask every proposal to describe the same completed result
Prepare one brief for prospective contractors, including the intended outcome, affected areas, retained features and any available design information. Ask each to identify removal, protection, preparation, supply, installation, making good and closeout. Use the same boundary for comparison.
Government consumer guidance recommends comparing written estimates and checking relevant experience and references. This does not mean the cheapest or most detailed-looking document is automatically the right choice. Clarify the work, qualifications, communication and responsibilities that matter to your project before deciding how to compare the totals.
An allowance is a named assumption, not free extra scope
Ask what an allowance covers: supply only, installation, delivery, accessories, tax or some defined combination. Identify the assumed quantity and specification, how the final selection is reconciled and what happens to any difference. An allowance without a clear boundary is difficult to use as a meaningful comparison.
Keep the actual chosen product and its total scope beside the allowance. A more expensive selected fixture can also have different installation requirements; a less expensive fixture does not automatically reduce every related labour cost. Use the existing allowance worksheet for entered arithmetic, then have the contractor explain the contractual reconciliation.
A contingency and an allowance do different jobs
A product allowance holds a defined selection assumption within the proposal. An owner’s contingency or reserve is an amount the owner chooses to retain for uncertainty. Neither is a guarantee that concealed conditions have been fully assessed or that all future changes are included.
Avoid counting the same scope twice. If a quoted amount already includes a product, do not add its full purchase price again to your budget. If a cost is genuinely unknown, retain the question rather than entering zero and treating the result as complete. The budget planner keeps entered amounts and the chosen reserve separate.
Define how an unexpected condition is handled
Ask who documents a discovery, what evidence is provided, how the affected work is paused or protected and who is authorized to decide the next action. An urgent discovery should still have a clear route for assessment and written agreement.
Distinguish investigation from corrective work. A contractor may need the relevant professional’s answer before offering an appropriate solution. Agree how any necessary assessment, revised scope, price and sequence will be recorded. A general phrase such as “extras as required” does not help the owner understand the decision being requested.
A change has more than one impact
Record what is being added, removed or substituted, why, and which document issue it changes. Ask for the effect on price, dates or dependencies, adjacent work and other people’s orders. Clarify any credit or exclusion as well as the additional charge. Keep acceptance and authorization tied to the actual change.
For example, moving a sink can affect cabinets, counter openings, plumbing and the sequence. The owner’s preference for the new location is not itself a complete change order. Ask the relevant parties to coordinate the implications before approving the work or releasing an affected purchase.
Use local consumer guidance for the actual agreement
Contracts and payment obligations have legal consequences. Have an appropriately qualified adviser review terms you do not understand, especially for substantial work or a dispute. This page is an organizing guide, not an interpretation of your contract or a statement of every provincial rule.
For Alberta projects, the province’s contractor guidance addresses matters including prepaid contracting. Check whether requirements apply and verify the business’s relevant status. Do not infer that a business licence, an attractive website, a referral or HAUSE intake confirms every qualification or contract term.
Make the comparison concrete
| Label | What to establish |
|---|---|
| Included | What work or product is described, and where does it stop? |
| Excluded | Who supplies the missing work and what depends on it? |
| Allowance | Exactly what is assumed and how is the final amount reconciled? |
| Unknown | Who investigates, decides and prices the resulting work? |
| Change | What is the complete effect, and who authorizes it in writing? |
WORKED PLANNING SCENARIO / FICTIONAL
A fictional quote with the lower headline total
One bathroom proposal includes disposal, wall preparation and a defined fixture allowance. A second has a lower total but excludes those items. The owners first put both proposals into the same scope table and ask for the missing boundaries and tax treatment to be explained.
They then compare the complete alternatives and the remaining uncertainty. The exercise does not calculate a fair local market price or determine which contractor should be hired; it makes the decision more understandable.
YOUR TAKEAWAY
Bring these questions.
- Are proposals based on the same current scope and documents?
- Does every allowance have a defined boundary and reconciliation method?
- Are unknowns kept separate from costs confirmed at zero?
- Who may authorize a change, and how is its complete effect recorded?
- Which local consumer, qualification and contract questions need independent confirmation?
