Energy renovation in Braine-l'Alleud: improve your EPC and reduce your bills
In a municipality like Braine-l'Alleud, where many homes have an EPC certificate of D or E,
energy renovation represents both a growing obligation and a significant opportunity for enhancement. New Walloon regulations are gradually imposing a minimum level of energy performance during sales and rentals: anticipating these requirements protects the value of your property.
Avenir Rénovations Braine-l'Alleud offers you a coherent and progressive energy renovation plan, in connection with a certified housing auditor:
- Roof and attic insulation: installation of mineral wool, blown cellulose, or PIR panels depending on the roof configuration (sloped, flat, habitable or lost attics). This is the most cost-effective renovation in terms of energy savings.
- External wall insulation (EWI) or internal wall insulation (IWI): choice of technique based on the architectural configuration of the building and aesthetic constraints, particularly in the well-maintained residential areas of Braine-l'Alleud.
- Window and glazing replacement: triple glazing or high-performance double glazing, PVC, wood, or aluminum frames with thermal break, installation of entrance doors with security certification.
- Installation of a new heating solution: air/water heat pump combined with underfloor heating, high-efficiency condensing boiler, pellet stove with hot air distribution, hybrid systems.
- Controlled mechanical ventilation (CMV): essential in a well-insulated home to renew indoor air, prevent condensation, and ensure air quality. Simple or double flow systems with heat recovery.
- Solar energy production: orientation and shading study, installation of photovoltaic and/or thermal solar panels, optimization of self-consumption.
Bathroom and kitchen renovation in Braine-l'Alleud
The kitchen and bathroom are the two rooms that concentrate the majority of finishing work. They require simultaneous intervention from many trades — plumbing, electricity, tiling, carpentry, painting — and demand flawless coordination to meet deadlines and avoid defects.
For
bathroom renovation in Braine-l'Alleud, we offer custom design: walk-in shower with glass partition, freestanding or whirlpool bathtub, wall-mounted vanity unit, large format or zellige effect tiling, designer faucets, built-in storage niche, electric or hydraulic towel warmer. Each installation complies with Belgian waterproofing and electrical safety standards in wet areas.
For
kitchen renovation in Braine-l'Alleud, our team designs spaces that combine functionality and aesthetics: custom or semi-custom base and wall cabinets, quartz, granite, or high-resistance laminate countertops, tiled or lacquered glass backsplashes, integrated appliances, and a central island if the layout allows. We manage all plumbing, electrical, and ventilation connections.
Roof and facade renovation in Braine-l'Alleud
The roof and facade constitute
the protective envelope of your home. Their good condition directly affects the building's energy performance, air and water tightness, and its market value. In Braine-l'Alleud, we regularly work on concrete or clay tile roofs, natural or synthetic slates, and flat roofs in EPDM or bitumen.
Our roofing services include complete or partial roof replacement, refurbishment of the metalwork (gutters, downpipes, valleys, ridges), treatment and reinforcement of the framework, as well as insulation from the inside or outside. For flat roofs, we carry out waterproofing repairs, install rainwater drainage systems, and potentially create a green or accessible rooftop terrace.
For the facade, we offer high-pressure cleaning, repair of cracks and degraded coatings, application of new render or cladding, as well as the installation of an external thermal insulation system (ITE) to combine aesthetics and performance in a single intervention.
Interior and outdoor fit-out in Braine-l'Alleud
The houses in Braine-l'Alleud often have spacious gardens and generous volumes that offer great fit-out opportunities. Our agency carries out
custom fit-out projects, designed to enhance every space:
- Terraces and outdoor fit-outs: design and construction of terraces using natural slabs, large format outdoor tiles, composite wood or brushed concrete. Creation of pathways, pavings, and interior courtyards.
- Bioclimatic pergolas and covered outdoor spaces: installation of pergolas with adjustable slats, outdoor awnings, fences, and motorized gates, low consumption garden lighting.
- Loft fit-out: many houses in Braine-l'Alleud have usable lost attics. We carry out insulation, create a fixed staircase, install roof windows, and finish the work to create an additional bedroom, an office, or a playroom.
- Creation of dressing rooms and integrated storage: custom interior carpentry, workshop-style glass partitions, built-in bookshelves, optimized storage spaces in hallways and landings.
- Home studio and home office: fit-out of a professional workspace, soundproofed and wired, in your home or in a converted garage.
Home extension in Braine-l'Alleud: extension and storey addition
Land in the east of Brabant wallon is particularly tight. Expanding your home rather than moving is often the most cost-effective and least disruptive solution for families. Avenir Rénovations Braine-l'Alleud carries out extension and storey addition projects in accordance with the municipal urban planning regulations of Braine-l'Alleud and the provisions of the CoDT (Walloon Territorial Development Code):
- Traditional masonry extension: construction of a side or rear annex in bricks or concrete blocks, architecturally integrated into the existing house, to create an enlarged living room, a master suite, or an additional living space.
- Timber frame extension: a quicker and often more cost-effective solution for small extensions, with thermal performance superior to traditional masonry. Ideal for villas with gardens in Braine-l'Alleud.
- Storey addition for single-storey houses: Braine-l'Alleud has many bungalows and single-storey houses from the 70s. The storey addition is often technically and financially interesting to double the living space without affecting the footprint.
- Veranda or glazed extension: a bright living space between the interior and garden, heated and usable all year round thanks to high thermal performance glazing.
For each home extension project, we handle the urban planning permit application with the municipality of Braine-l'Alleud, any consultations with the delegated official from Brabant wallon, and the mandatory PEB procedures for extensions over 50 m².

FAQ — Frequently Asked Questions about Avenir Rénovations Braine-l'Alleud
What is the difference between Avenir Rénovations and an independent craftsman?
An independent craftsman operates within their own trade. If your project requires a mason, an electrician, a plumber, and a tiler, you must find, coordinate, and manage any scheduling conflicts yourself. Avenir Rénovations Braine-l'Alleud takes care of this coordination in its entirety. You sign a single contract, have a single point of contact, and only need to approve the key stages of the project.
Do I need to obtain a building permit for my renovation work in Braine-l'Alleud?
This depends on the nature of the work. Generally, interior work (kitchen renovation, bathroom, coverings,
painting) does not require a permit. However, work affecting the exterior envelope of the building (facade modification, changing
joinery visible from the road, home extension), or those modifying the volume of the building (storey addition, extension) may be subject to a permit depending on the dimensions and location. Our team will provide precise information during the initial visit and will handle administrative procedures if necessary.
How much does a complete house renovation cost in Braine-l'Alleud?
The cost of a complete renovation varies significantly depending on the initial condition of the property, its size, the level of finishes chosen, and the work to be done. As a guideline, a complete renovation of a four-sided house of 150 m² in Brabant Walloon generally ranges between €80,000 and €250,000. To obtain an accurate and personalized estimate, nothing replaces the free visit from our agency manager to your home.
Does Avenir Rénovations Braine-l'Alleud also work on apartments and buildings?
Yes, we work on all types of residential properties: single-family homes,
apartments, duplexes, apartment buildings, farms, and character buildings. We also collaborate with property managers for the renovation of common areas. Each project, regardless of its size, benefits from the same level of organizational rigor and follow-up.
What are the usual timelines to start a construction site after signing the estimate?
After signing the contract, the start time depends on the complexity of the project and our construction schedule. For standard work (bathroom renovation, kitchen, flooring), we can generally start within 4 to 8 weeks. For larger projects requiring a building permit or extensive planning, the timeline can range from 2 to 5 months. These timelines are specified in your contract and are adhered to.
