Make the booking specific
Tell the company whether you need routine maintenance, a report for a property decision or an investigation of a symptom. Identify an open fireplace, insert, freestanding stove or gas appliance as accurately as you can. Send the model name from an accessible label or existing manual; do not dismantle the appliance to find it.
Mention smoke, unusual odor, water, falling material or animal sounds before the visit. A company booked for straightforward sweeping may not bring the equipment or specialist needed for diagnosis. Ask whether inspection, camera work and cleaning are included or separately priced.
Agree access and cooling requirements
Ask how long the appliance must remain unused before arrival and follow that instruction. Never present the technician with a hot appliance or recently removed hot ash. Clarify whether they need access to a cleanout, basement, attic, crawl space or roof and who will move an insert if access requires it.
Describe steep roofs, locked gates, shared access, parking restrictions and pets. The goal is to let the company plan safe access, not to prepare ladders or go onto the roof yourself. If weather prevents roof work, ask which portions of the appointment can still proceed and how the return visit is charged.
Prepare the room without disturbing evidence
Move fragile objects and furniture out of the agreed work area. Keep children and pets away during service. Confirm who supplies floor protection and dust containment. Do not scrape deposits, remove a blockage or vacuum ash with an ordinary household vacuum to make the fireplace look cleaner.
If a stain or fallen fragment prompted the call, photograph it and tell the technician where it was found. Do not collect material from an unsafe area. A dated photograph and a short timeline are often more useful than a bag of unidentified debris.
Have your information ready
Put previous reports, invoices, appliance instructions and known repair details together. Note roughly how the appliance is used, the fuel, when it last worked normally and any recent changes to windows, fans, roof or insulation. It is acceptable to write 'unknown' rather than guess.
Before work begins, confirm the price assumptions and how additional work is authorized. An unexpected finding should lead to an explanation and an agreed change in scope, not an unexplained charge at the end of the appointment.
Close the appointment with a record
Ask what was cleaned, what was inspected and what could not be accessed. Keep labelled photographs and any restrictions on use. A receipt saying 'chimney serviced' is less helpful than a record identifying the appliance, vent and remaining concerns.
If repair is recommended, request the observed defect, its location, the proposed correction and the basis for urgency. Do not assume that a completed cleaning means the system has been cleared for use. Ask the technician to state the next step explicitly.
