In Écublens, located at an altitude of 426 meters, the climate imposes specific requirements on housing.5 °C, the thermal performance of your home is crucial.
An outdated bathroom, often located on a cold-exposed wall, can become a significant source of heat loss or present risks of condensation.
Undertaking a renovation not only improves your comfort but also enhances the insulation and waterproofing of your walls.
The ideal time to plan these works is during milder months, avoiding periods with high frost risk. Managing heating and ventilation is essential to avoid problems related to humidity in a region with 2759 heating degree-days per year.
Modernizing your installation today means anticipating the energy needs of tomorrow and sustainably increasing the value of your property in this dynamic sector of the canton of Vaud.
The renovation of a bathroom is based on technical choices that dictate the durability of your investment.
Replacing a bathtub with an Italian-style walk-in shower is a frequent request in Écublens, but it requires a rigorous verification of the drainage slope available in the floor.
If the configuration does not allow for deep installation, extra-flat shower trays are available as a solution, though they change the final appearance.6 °fH), which is a major advantage for preserving your faucets and shower walls.
The choice of finish materials also plays a key role in daily maintenance. Prioritize smooth, non-porous surfaces that are easy to clean.
For wall and floor coverings, the trend is toward large formats that reduce the number of joints, thus limiting areas prone to mold.
Finally, thermostatic faucets and low-flow shower systems are wise choices to combine user comfort with responsible resource management, fitting perfectly into modern Vaudois building standards.
The building stock in Écublens presents a diversity linked to construction eras.
For buildings constructed before the 1990s, special vigilance must be paid to the potential presence of hazardous materials, such as asbestos in tile adhesives, joints, or old vinyl floor coverings.
Before any demolition, a diagnosis by a professional is recommended to avoid the dispersion of harmful dust during the work. Older pipe networks can also show structural weaknesses or insufficient diameters for new sanitary installations.
In more recent constructions, the challenge often lies in ventilation and insulation. A perfectly sealed bathroom must imperatively be equipped with an efficient air renewal system to prevent moisture accumulation.
Check that your current electrical network complies with current standards to support new equipment (towel dryers, floor heating, LED lighting).
In case of doubt about the supporting structure, especially for major transformations, do not hesitate to consult an engineering office.
Anticipating these technical points guarantees the longevity of your project and the safety of the residents of your home in Écublens.
This guide does not establish a permit exemption. If your building or area is protected, check the constraints specific to your project.
For projects aimed at global energy improvement, aid is generally granted via cantonal or federal programs, but these must imperatively be requested before the start of work. Once the construction site has begun, grant applications are no longer receivable.
We advise you to consult the official portal of the canton of Vaud to identify current incentive measures related to thermal renovation.
On the tax side, renovation and maintenance work can, under certain conditions, be deducted from your taxable income.
Expenses that serve to maintain the value of your property are considered maintenance costs and can be deducted according to the tax rules in force.
It is recommended to carefully keep all detailed invoices from the companies involved as well as proof of payment.5.
Make sure to clearly distinguish between maintenance work and value-adding investments to optimize your future tax return with the help of an expert or by following the cantonal guidelines.
A renovation project in Écublens follows a rigorous chronology to ensure the success of the work. The first phase is planning, where you define your needs and obtain the necessary quotes.
Once the companies are selected, the preparation phase consists of emptying the room and protecting access to the home.
The construction actually begins with the demolition and evacuation of rubble, a crucial step for inspecting the state of the pipes and underlying insulation. It generally takes 2 to 4 weeks of construction during which your bathroom will not be usable.
Then follow the finishing works : installing new pipes, electricity, waterproofing floors and walls, then laying tiles or coverings. The final phase involves installing sanitary equipment, furniture, and finishes (painting, silicone joints).
For a comfortable construction site, it is advisable to plan this work outside of periods of extreme winter cold, even if interior work is protected.
Managing the drying process (especially of glues and mortars) is facilitated by stable atmospheric conditions, thus avoiding unnecessary delays.
Smooth coordination between the different trades, from plumber to tiler, is the key to respecting your initial schedule.
To avoid disappointment, start by establishing a precise list of your functional needs. Replacing a bathtub with an Italian-style walk-in shower requires checking the available drainage slope before any purchase.
Never neglect the asbestos diagnosis for old buildings before starting demolition. Ensure your quotes clearly detail each item, from materials to labor, to avoid unexpected surcharges.
Plan a contingency solution for your sanitary needs during the 2 to 4 weeks of construction. Hard water scales faucets and walls quickly: plan for easy-to-maintain surfaces.
Checklist before requesting quotes : 1. Define a clear budget without forgetting a 10% safety margin. 2. Check the technical feasibility of your wishes (water supply, drainage). 3. Request several comparable quotes from local companies. 4.
Check the availability of craftsmen according to the desired schedule. 5. Inquire with the municipality about any urban planning constraints related to your building. 6. Anticipate rubble management and site cleanup. 7.
Check the condition of your current electrical panel in relation to the new power requirements of your future equipment.
