Creosote assessment and removal

Have the contractor explain the deposit, proposed method and compatibility with the chimney or liner. Ask whether repeat visits, additional inspection or repair may be needed. Do not try to burn deposits out.

Request before-and-after documentation and a clear account of material that remains. Ask whether there are unresolved conditions that prevent reuse and what operating or fuel issues should be reviewed.

Describe wood storage, frequency of use and any past chimney fire. Keep the appliance unused until the professional has assessed the concern.

Confirm appointment access, who will be present and what records to have ready. Preparation does not mean dismantling the appliance, climbing the roof or reproducing a dangerous symptom.

• Confirm experience with your chimney type and appliance model. A company that cleans masonry fireplaces may not service every gas or pellet appliance.
• Ask who performs the work, what credentials apply to that person and how you can verify them with the issuing organisation.
• Check current insurance and any local licensing or permit requirements directly. A profile badge is not proof of every qualification.
• Compare access, materials, diagnostic work, disposal, exclusions and follow-up. A lower total can represent a smaller scope.

Use the local guide to prepare questions about access, building history and the authority responsible for your address. The service brief is national guidance; local permits and current burn restrictions must be checked separately.
