01 — Scope
What we do at your place
One technician comes to Londerzeel, one itemised invoice.
Across an area of 36.3 km2 with 18620 inhabitants in the arrondissement administratif de Hal-Vilvorde, residential heating engineer requests in Londerzeel span varied systems. Calls frequently involve condensing gas boiler service, conventional gas boiler service, oil boiler service with nozzle and sweep included, or flue sweeping. When speaking to an operative on the telephone, please specify your current symptoms, such as whether you require circulation pump replacement, expansion vessel replacement, thermocouple or sensor replacement, or bleeding and balancing the radiator circuit.
Oil boiler service
Nozzle replacement, combustion chamber cleaning, flue sweeping where needed, burner adjustment and flue gas measurement. Mandatory annual certificate.
Boiler repairs
Error code, lockout, no hot water, burner that will not start. Fixed-fee diagnosis, then repair amount stated before any part is ordered.
Pump, vessel, valve
Replacement of the parts behind pressure and circulation faults: pump, expansion vessel, safety valve, automatic air vent. Part reference shown on the invoice.
Radiators and thermostats
Bleeding and balancing the circuit, thermostatic valve replacement, fitting a room or smart thermostat. Connection to the existing circuit where needed.
Boiler replacement
When repairing no longer makes sense: written quote for a condensing boiler, removal of the old one, connection, commissioning and first certificate.

05 — Questions
Your questions before we arrive
What people in Londerzeel 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 →
How long for a boiler repair in winter?
The time is given on the phone according to the day's round; a home without heating or hot water comes before a planned service. If a part must be ordered, we give the supplier lead time before you confirm, and we get the system running provisionally when it is safe to do so. Request a quote →
What should I prepare before the heating engineer's visit?
Clear access to the boiler and gas meter, and find the last service certificate and the manual if you have them. A WhatsApp photo of the rating plate and the error code lets us bring the right part and often avoid a second visit. See the prices →
Conventional gas boiler service (certificate included) in Londerzeel: how much does it cost?
The Belgian market in 2026 sits between €100 and €135 excluding VAT for conventional gas boiler service (certificate included), night and weekend surcharges excluded.
