What the service should establish
Ask the professional to identify the existing liner and document the condition that supports repair or replacement. A proposal should specify the connected appliance and fuel, compatible system, sizing basis and applicable manufacturer instructions.
Where the scope stops
A generic length of pipe and a total price do not explain a complete installation. Ask about access, insulation where required, connections, termination and completion documentation. Requirements depend on the product and system, not a universal directory checklist.
The Advisor standard · Define before deciding
A liner proposal should describe a system, not just pipe
Ask for the connected appliance, fuel, existing liner type and location of the documented concern. A recommendation should explain why repair, relining or another response is being proposed. The chosen system must be evaluated in relation to the appliance and the existing construction, not simply the visible chimney height.
What a comparable proposal looks like
Request a named product system, its relevant instructions and a written explanation of included connections, termination, access and insulation where required. Avoid substituting parts or deciding dimensions from online examples. Ask who confirms applicable permits and how the completed work will be documented for future servicing.
Four items to take away
- Observed defect and affected flue
- Named system and appliance match
- Connections, access and exclusions
- Product documentation and completion record
Can the cheapest liner material be substituted?
Do not assume that. Product selection depends on the appliance, fuel, installation conditions and applicable requirements. Ask the installer to explain the specified system and any alternative in writing.
