What to put in the scope

  1. Identify the flues and their termination requirements.
  2. Measure mounting surfaces and inspect their condition.
  3. Specify compatible materials and secure installation.

Where this service stops

A new cap does not repair leaking flashing or a cracked crown. A cap also cannot be assumed to fix a smoke problem without diagnosis.

The evidence to keep

Request product details, attachment method and photos of the installed termination. Confirm maintenance access remains possible.

Record who performed the work, the date, the identified appliance or flue and any follow-up recommended. When photos are provided, ask for labels that let another contractor understand what they show. A clear record helps distinguish a new condition from an old recommendation at the next visit.

Questions before accepting a proposal

  • Is this cap compatible with the appliance and vent?
  • How will it be attached?
  • Can the flue still be swept and inspected easily?

Ask the company to identify travel, roof access, additional flues, permits and disposal separately where they affect the price. Confirm how unforeseen conditions will be explained and authorized. Keep the original estimate alongside any agreed changes.
