Licensed trade
Plumbing and electrical work may require licensed professionals, permits and inspections.
Choosing qualified help
Choose the professional for the decision—not only the product being sold.
Flood resilience can involve plumbing, drainage, electrical, structural, geotechnical, building-envelope, insurance and municipal questions. One provider may not cover every discipline.
- Ontario-focused
- Plain-language guidance
- Risk reduction, not guarantees
The essential answer
Define the problem, ask who is qualified for the relevant scope, verify licences and insurance where applicable, request clear limitations and compare documentation—not only price.
Who this guide supports
Use this page when the property, question or decision matches one of these situations.
- Homeowners seeking an initial flood-risk assessment
- Residents comparing installation proposals
- Buyers needing specialist due diligence
- Owners recovering from a flood and planning repairs
Understand the system
Four parts of the decision deserve separate attention.
Inspector or assessor
Can document visible conditions and recommend further specialist investigation within a defined scope.
Engineer or specialist
May be needed for structural, grading, drainage, geotechnical or complex building-system decisions.
Municipal authority
Confirms local permit, programme and inspection requirements; it does not select a contractor for you.
Guidance 1
Start with a written problem statement
Describe what happened, when, where and under what conditions. Share photos and records without prescribing the solution.
A provider who understands the pathway can explain why the proposed scope addresses it.
- Ask what evidence supports the recommendation
- Request excluded and unresolved risks
- Confirm who designs and who installs
- Identify required third-party review
Guidance 2
Verify business and professional credentials
Check trade licences, insurance, corporate identity, references and any professional registration relevant to the work.
An RSM education-based credential should not be represented as a government licence or municipal approval.
- Verify names against official registries
- Request proof of liability coverage
- Confirm permit responsibility
- Avoid pressure to sign immediately
Guidance 3
Compare complete scopes
Lowest price is not meaningful if one proposal excludes permits, restoration, alarms, backup power, documentation or maintenance handover.
Require itemized costs, assumptions, change-order terms and post-work records.
- Compare equivalent work
- Confirm warranty terms
- Define cleanup and restoration
- Require operation and maintenance instructions
Practical workflow
Move from observation to a documented next step.
- 1
Write the observed problem and desired decision
- 2
Identify the disciplines involved
- 3
Verify credentials, insurance and permit responsibilities
- 4
Compare written scopes, exclusions and documentation
- 5
Keep final records and schedule maintenance
Homeowner checklist
Record each completed item and create a follow-up action for anything unresolved.

Official source pathway
Use current public sources for emergency, insurance, programme and technical context.
RSM summarizes and connects information but does not replace the issuing authority. Review the current official page before acting.
Frequently asked questions
Clear limits help homeowners make better decisions.
Does RSM certify contractors as government-approved?
No. RSM credentials are education-based professional-development pathways and do not replace licences, permits or authority approval.
Who should assess lot grading?
The appropriate professional depends on complexity and local requirements and may include qualified drainage, engineering, landscape or municipal expertise.
Should I get more than one quote?
For significant work, comparable written proposals can help evaluate scope, assumptions and value.
What should be delivered at project completion?
Permits, inspection records, product information, warranties, photos, test results and maintenance instructions.
