Masonry and chimney crown repair

Identify the courses or joints affected, mortar compatibility, crown work, access equipment and debris removal. Ask whether historic-property review or permits apply to this address before agreeing to a visible alteration.

Obtain photographs and a measured scope. Clarify how adjoining roofing and flues will be protected and whether other specialists must assess structural movement.

Keep people away from falling material. Record damage from a safe ground location and share previous patching or water problems.

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.
