Find a chimney sweep contractor—and know exactly what to ask.

Frequency depends on the appliance, fuel, use, deposits, system condition and applicable guidance. Ask a qualified chimney professional to recommend an interval for your system after assessing it; do not rely on a universal calendar rule.

No. Sweeping removes deposits and debris. An inspection evaluates condition within an agreed scope. A visit can include both, but the written quote should say what level of inspection and documentation is included.

Include the appliance and fuel type, property style, last known service, observed symptoms, requested service, access constraints and any useful photographs. Ask every company to quote against the same brief.

Request a service record, findings, limitations, photographs where appropriate, and clearly separated recommendations. For repairs, keep the final scope, product information, warranty and invoice.

A phone discussion can help define the likely service and prepare an estimate, but many defects require on-site access or camera inspection. Treat remote opinions as preliminary unless the contractor clearly states otherwise.
