Plumber in Belair, for houses and residences
In Belair many homes are houses on several levels, with a cellar, garage and garden, or residences with an underground car park. When a drain blocks, the water often shows up in the basement first.

A house on several levels: where is the blockage?
In a Belair house, waste from the toilet, kitchen, bathrooms and utility room runs down to the basement, then out to the sewer through a pipe under the garden or driveway, with one or more inspection chambers.
The lowest point is often the floor drain in the utility room or garage. If dirty water comes out there, the blockage is further along, in the pipe to the street: clearing the sink or toilet will not help. If only one fixture drains slowly, the problem is in its trap or branch pipe.
Another common case in large houses: a guest bathroom or basement toilet that is rarely used. The water in the trap evaporates and sewer smells come up. Running the tap is often enough; if the smell stays, we check the trap and the vent.
When water comes up in the basement
Stop using water in the whole house: washing machine, shower, toilet. Do not pour chemicals into the floor drain, they stay in the water we have to pump out. Call us or send a photo of the open inspection chamber on WhatsApp.
On site, we open the nearest chamber, clear the pipe with high-pressure jetting up to 200 bar, then run a camera through to see the cause: tree roots, grease, a sagging or displaced pipe. On request, you get a written report with photos, useful if you need to make a claim with your insurer.
Unblocking guaranteed for 1 month: if it blocks again in the same place within the month, we come back free of charge.
In Belair’s residences
Along the route d’Arlon and on residential streets such as avenue Gaston Diderich or avenue du X Septembre, there are also many upmarket apartment buildings. The waste stack is shared: if water comes up in your flat when a neighbour uses theirs, tell the building manager (syndic), as it is a common part.
To get into the building, give us the door code or arrange to let us in, and tell us whether the technician can park in the underground car park. If the stack is blocked, we can work for the syndic and invoice them directly: see building managers and businesses.

Frequently asked questions
Dirty water is coming out of the floor drain in my cellar. What should I do?
Stop using water in the whole house and call us. The blockage is usually in the pipe to the sewer. We clear it through the inspection chamber and use a camera to find the cause.
Can roots from garden trees block the drain?
Yes, roots get in through the joints of old pipes. The camera shows it. Jetting clears the way, and we show you the footage so you can decide what to do next.
My insurer wants evidence. What do you provide?
Before and after photos, a job report and an itemised invoice. You pass them on to your insurer with your claim.
Do you come to Belair in the evening and at weekends?
Yes, 24/7, every day. The price is given on the phone before we travel, and that is the price you pay.
