Heating care

A boiler service that helps avoid a bad-timing breakdown.

Annual checks, pressure problems, cold radiators and planned replacements. We tell you what is worth repairing and what is not, and we will say so when a repair is the better value than a new unit.

Before we arrive

Useful pricing, not a vague promise.

These are the numbers we work from. A callout covers diagnosis and the first hour on site; anything larger is quoted in writing before it starts.

Callout

From €95

Diagnosis and the first hour, in the Brussels area during normal hours.

Boiler service

From €145

Full maintenance visit with a written condition report.

Planned work

Written quote

Scope, parts and labour set out before you commit to anything.

What happens next

Four steps, and you know the cost by step two.

01

You describe it

Send the room, what you can see and whether water is still moving. Photos help. We reply the same working day.

02

We price the visit

You get the callout cost and the likely cause before anyone is booked in, so there is no surprise at the door.

03

We diagnose on site

We find the actual fault rather than replacing the nearest part, and we show you what we found.

04

You approve the work

Anything beyond the callout is quoted in writing first. Nothing further happens until you say yes.

Fixed callout, no hourly creep

The callout covers diagnosis and the first hour. You are told before that runs out.

Next step

Send the room, a short description and whether water is moving now. We reply the same working day with the likely cause, what a visit would cost and the first date we can be there.
