Insulation work in Walloon Brabant (1300–1495): loft and roof, walls, floor and façade. A team available in Wavre, Nivelles, Ottignies-Louvain-la-Neuve and across the whole province, a free technical survey scheduled within 48 hours and the Walloon subsidies arranged and deducted for you — from the detached houses of Walloon Brabant to the terraced homes of the town centres.
We work across the whole province of Walloon Brabant with an insulation team that knows the area — from the detached houses of the residential zones of Wavre and Braine-l’Alleud to the terraced homes of central Nivelles and the cottages of the leafy districts of Ottignies-Louvain-la-Neuve.
The technical survey is done at your home, with no call-out charge and scheduled within 48 hours ; we measure heat loss area by area, check the condition of the building and cost the right insulation jobs. The same team then follows the whole project through to the finishing touches.
We know the Brabant building stockBeyond Wavre and Nivelles, we also insulate in Ottignies-Louvain-la-Neuve, Braine-l’Alleud, Tubize and Waterloo, as well as your loft, your walls and your façade — the same team, the same lead times across the whole province of Walloon Brabant.
Walloon Brabant relies on subsidies from Wallonia. Here are the levers we arrange and deduct directly from your bill, with nothing for you to pay up front.
For insulating the roof, walls and floor in Wallonia, scaled according to your income and the performance level achieved. A home audit by an accredited auditor is often required to unlock the subsidy — we guide you and coordinate the audit.
For a home over 10 years old, VAT drops from 21% to 6% on the supply and installation of the insulation. Applied directly on your quote.
We coordinate the accredited home audit, build the Habitation subsidy file and deduct it from your bill: you pay nothing up front and fill in no forms.
The detail of the amounts, conditions and income ceilings is on our insulation price & subsidies page. We build the entire file: you pay nothing up front and fill in no forms.

The most cost-effective job on the detached houses of Walloon Brabant: blown-in loft insulation or sloping rafters insulated under the pitch, with no work on the façade. Immediate saving on the heating bill.
Discover →From the inside or by cavity injection on double-wall buildings: we remove the cold walls without adding to the project or reducing the living space.
See →External thermal insulation with render or cladding: maximum performance and a renovated façade in one move, ideal for the cottages and villas of the residential zones.
Explore →You almost always start with the roof and loft: it’s the biggest source of heat loss and the best gain-to-cost ratio, especially on the detached houses of Walloon Brabant. During the free technical survey, we measure heat loss area by area and propose a costed order of priority, suited to your home and your budget.
As Walloon Brabant comes under Wallonia, you can benefit from the Habitation subsidy for insulating the roof, walls and floor (scaled according to your income and the performance level achieved) and from 6% VAT if your home is over ten years old. Note that these are not the Brussels Renolution subsidies. We arrange and deduct these subsidies; all the amounts are detailed on our price & subsidies page.
In Wallonia, a home audit by an accredited auditor is often required to unlock the Habitation insulation subsidy and set the order of the work. We refer you to an accredited auditor, coordinate the audit and then build the subsidy file on your behalf.
It depends on the job: blown-in loft insulation is often done in a single day, cavity wall injection in one to two days, while external façade insulation generally takes a few days depending on the surface area. The exact lead time is firmly confirmed when you sign the quote.
Yes, completely: the call-out to your home in Walloon Brabant, the heat-loss diagnosis and the costed quote are free and with no obligation. You pay nothing until you have validated your insulation project.
