Why choose Avenir Renovations?
A well-designed plumbing system brings peace of mind every day
An aging, undersized, or poorly installed system can lead to significant inconveniences or even structural damage. It is essential to intervene before major problems arise by anticipating needs and risks.
Risks of leaks or infiltration
Worn seals, clogged pipes, poorly made welds, embedded networks without maintenance… These elements are the source of micro-leaks that can eventually cause serious damage: mold, subsidence of floor, wall infiltration, corrosion of load-bearing materials. Regular checks or a complete renovation may sometimes be necessary.
Lack of pressure or poor drainage
An inadequate plumbing system leads to usage issues: insufficient pressure at the faucet, unstable lukewarm water, backflow in traps, or noise in the pipes. These inconveniences may be due to poor sizing, unbalanced piping, or an outdated network.
Non-compliance with current standards
In the case of sale, renovation, or home insurance, compliance updates to the installations may be required. This includes the separation of drinking water and wastewater networks, protection against backflow, anti-scald devices, permitted materials, and regulatory flow rates. A compliant installation is also a guarantee of value for your property.
Our plumbing services for renovation and new installations
At Avenir Rénovations, we work in all areas of plumbing, from simply replacing a faucet to completely creating a water network. Each project is studied according to your configuration, needs, and budget.
Why choose Avenir Rénovations for your plumbing work?
With Avenir Rénovations, you benefit from compliant, precise, and durable work carried out by professional plumbers, respecting your schedule and your peace of mind.
We analyze your current usage, the layout of the home, space or circulation constraints, as well as your future projects. This allows for a scalable installation that is well-sized and easy to maintain. A well-thought-out network reduces risks, optimizes flows, and guarantees better long-term comfort.
We work closely with other trades (tilers, electricians, drywallers) to ensure that plumbing runs, openings, formwork, or technical ducts are integrated from the start, avoiding adjustments and intervention conflicts. Cleanliness of the site is a priority at every stage.
Our installations comply with current technical requirements: sizing of pipes, minimum drainage slopes, authorized materials, anti-backflow safety devices, anti-legionella systems, valves, drainers, etc. Everything is planned to avoid unpleasant surprises, including in the event of inspection or resale of the property.

FAQ – plumbing and renovation: your frequently asked questions
Can I replace my bathtub with a shower without modifying the entire plumbing system?
Yes, if the existing drainage is well positioned and in good condition. However, in most cases, the trap and drainage slope will need to be adjusted, especially for a walk-in shower. We conduct an on-site assessment to check feasibility and offer you an appropriate, aesthetic, and compliant solution.
What plumbing materials are recommended?
It depends on the use and your project:
- Copper: very durable, ideal for hot water and visible installations
- Pex: flexible, economical, easy to install in screeds or partitions
- Multilayer: combines the advantages of Pex and copper, with great stability
- We select materials based on pressure, temperature, expected longevity, and your budget.
Should I have my plumbing regularly maintained?
Yes. Certain equipment like water heaters, gas boilers, or softeners require regular maintenance. This helps prevent breakdowns, leaks, and prolongs the lifespan of the installation. We offer one-time maintenance or maintenance contracts at suitable frequencies.
Can I benefit from a reduced VAT rate for my plumbing work?
Yes, if the property is over 10 years old and the work is carried out by an approved company, you can benefit from a reduced VAT rate of 6%. We check your eligibility and include this information in our quote.
