Documents handed over on site04 — Questions
Your questions before we arrive
What people in Mont-Saint-Guibert ask before confirming.
Can the service fee quoted go up on site?
Not for the service itself: the fee depends on the boiler type you gave and includes cleaning, checks, combustion analysis and certificate. Only a flue sweep or a worn part found on site is added, and only after the engineer has shown and priced it to you. See the prices →
What guarantee covers a replaced part?
New parts are covered by the two-year legal conformity guarantee under Belgian law, plus the manufacturer's warranty where it is longer. The labour guarantee is written on the invoice. An identical fault on the same part within that period is redone without a diagnosis fee. Request a quote →
Breakdown tonight: emergency or appointment tomorrow?
A smell of gas is an emergency for Sibelga or 112, not for a heating engineer. For a boiler that has stopped without danger, next-day working-hours appointment costs the normal fee; an evening or weekend visit carries the surcharge stated on the phone. We give you both options and the price of each. See the prices →
