Why choose Avenir Renovations?
Healthy plumbing means a peaceful home
We only think about plumbing when it causes problems. However, the warning signs are often visible long in advance.
Discreet leaks
Leaking joints, hardened seals, corroded pipes in a wall or under a slab: a small leak can act for months before appearing as a stain or warped floorboards. In a terraced house, it can even manifest in the neighbor's home.
Low pressure and slow drainage
A drop in flow when two faucets are opened, a shower that alternates between hot and cold, a drain that gurgles: these are often symptoms of old pipes, scaled or undersized for current usage.
Limescale, very present in old galvanized pipes, gradually reduces their inner diameter.
Installations from another era
In houses built before the 1960s, there may still be sections of lead pipes or cracked cast iron drains. Replacing them is a real health gain and avoids repeated repairs.
Our plumbing services in Leuven
Avenir Renovations takes care of your plumbing work in Leuven, from installation to repair. Our interventions ensure reliable, functional, and suitable equipment for your home.
Why trust your plumbing to Avenir Rénovations in Leuven?
Avenir Renovations supports you in your plumbing work in Leuven with rigorous follow-up. Each intervention prioritizes compliance, coordination of craftsmen, and reliability of installations.
We identify the type of pipes, the location of valves, the layout of drains, and the condition of the sewer connection. This survey prevents replacing a new section while leaving behind an old section.
In a renovation, plumbing takes precedence over plastering, tiling, and the kitchen. Your Project Manager arranges the order of interventions so that chases are made only once, in the right place.
Adapted sections, minimal slopes, permitted materials, backflow preventers, and safety devices: the installation is carried out according to the current technical regulations, with a guarantee on the work performed.
Each connection is pressure tested before being closed in a wall or under a slab.
What is the cost of plumbing work in Leuven?
The cost varies depending on the accessibility of the pipes, materials, and the scope of the project. Price ranges including 6% VAT when the property is over ten years old.
| Type of work | Factors affecting the price | Indicative price including VAT |
| Complete replacement of water distribution (house) | Number of water points, concealed or exposed pipes | 4,000 to 9,000 € |
| Replacement of cast iron or lead drains | Length, access in the basement or under the slab | 1,500 to 5,000 € |
| Separation of rainwater and wastewater on the property | Length of trenches, access to the garden | 3,000 to 10,000 € |
| Rainwater tank with pump, installed and connected | Volume, excavation, circuits to connect | 3,500 to 7,000 € |
| Replacement of an electric or gas boiler | Volume, location, flue gas evacuation | 1,200 to 3,500 € |
| Installed water softener | Capacity, connection | 1,500 to 3,000 € |
| Non-destructive leak detection | Technique used, access | 250 to 600 € flat rate |
Before estimating, a camera is passed through the drains if necessary, the pressure of the network is tested, and the condition of the drains in the basement is checked. Each item is then detailed in the quote.
Example: for a row house in Kessel-Lo affected by a new separate network, the separation of water with a five thousand liter tank connected to the toilets often costs between 7,000 and 12,000 euros including VAT, with drainage control included.
Procedures and grants for plumbing work in Leuven
The obligation to separate waters
When a separate network is installed in your street, the separation of rainwater and wastewater on your plot is generally mandatory. The letter from the City or the drainage manager sets a deadline. The work is the responsibility of the owner, and financial assistance is sometimes provided during these projects.
The inspection of private drainage
In Flanders, a separation of waters or a new connection is generally accompanied by an inspection of the private drainage, carried out by an accredited organization before the final connection. We carry out the work to ensure it passes this inspection on the first attempt and prepare the installation plans.
Rainwater tank
For new construction or an extension subject to a permit, Flemish regulations on rainwater often require a tank or infiltration system. In renovation, a tank is not always mandatory, but it significantly reduces the water bill if used for toilets and washing machines.
VAT and assistance
Plumbing work in a home over ten years old is charged with a VAT of 6%. There is no regional grant for plumbing itself. A thermodynamic boiler, however, can be subsidized by Mijn VerbouwPremie, regardless of income category.
Important to know about the plumbing of an old house
Identifying lead pipes
Lead is dull gray, scratches easily with a fingernail, and has a dull sound. It is mainly found near the water meter, in the oldest structures in the center and the first streets around. If in doubt, check during the visit.
Finding a leak without breaking
In most cases, a camera in the drains, pressure testing, or acoustic or thermal detection is sufficient to locate the leak. Only the precise area is opened afterwards.
Hard water
A water softener protects the boiler, faucets, and appliances. It requires some space, often in the basement, and regular replenishment of salt. It is sized according to the measured hardness of the water and the household's consumption.
Correct actions in case of a leak
First, close the main valve near the water meter, then cut off the electricity if water is near an electrical installation. Once the situation is stabilized, locate the leak and propose a lasting repair.
Frequently asked questions about plumbing in Leuven
What to do if tap water changes color or taste?
Brownish water at the first draw often comes from old galvanized pipes that are rusting. Let it run for a moment, and if the problem persists, have the interior installation checked. The water distributor can also indicate if there is a problem with the public network.
Should lead pipes be replaced?
Yes, it is recommended. Lead can dissolve in water, especially when it stagnates in the pipes, and poses a health risk, particularly for young children. Replacing with multilayer or copper pipes permanently resolves the issue.
How long does a complete plumbing renovation take?
For a terraced house, expect one to two weeks for water distribution and drains, excluding finishes. A separation of waters generally takes three to eight days depending on the length of the trenches.
What to do if water rises in the basement during heavy rains?
This is often a sign of a saturated sewer backing up into the house. A backflow valve on the drainage, sometimes complemented by a sump pump, protects the basement. The separation of waters also reduces this risk.
Are there drainage works in your street?
If a municipal project is announced, it is better to prepare the separation of waters on your property before it arrives in front of your house. The delay is often shorter than expected.
