What the service should establish
Ask for photographs and a description of the deposits, the proposed removal method and its compatibility with the liner. Inspection levels and informal descriptions of creosote stages are different concepts; clarify which one the contractor means.
Where the scope stops
A chemical cleaning product is not a replacement for professional inspection and mechanical cleaning. Never attempt to burn deposits out. The contractor should explain removal limitations and what remains unresolved after the work.
The Advisor standard · Define before deciding
Ask what makes the proposed treatment different from a routine sweep
A homeowner cannot reliably specify a removal method from a dark photograph. Ask the professional to describe the deposit, its location and why standard brushing would not adequately address it. Request an explanation of how the proposed method suits the existing liner and what limitations may remain.
What a comparable proposal looks like
If a proposal involves more than one visit, ask for the sequence, access requirements and the point at which results will be reassessed. Do not infer permission to use the appliance between visits. The contractor should provide instructions appropriate to the actual product and system rather than relying on a generic article.
Four items to take away
- Deposit condition and location
- Method and compatibility basis
- Visit sequence and authorization
- Post-removal observations
Are creosote stages the same as inspection levels?
No. Those phrases refer to different subjects. Ask the contractor whether a number describes an inspection scope or an informal deposit classification, then have the actual condition described in words.
