Our story
From a simple idea to the one-stop shop for energy
Renovating often means juggling a host of companies: one for the windows, another for solar, a third for heating… and just as many quotes, lead times and diluted responsibilities. wendows was born from one conviction: all of this can rest in the hands of a single partner.
We brought together five energy-renovation trades to offer a clear journey, from the first advice through to after-sales service. Our teams coordinate the work, prepare your grant applications and deduct them directly from your bill.
“One home, one project, one point of contact — that’s all the one-stop shop changes.”
Today, wendows operates across Belgium with teams close to you. Our goal stays the same: to make energy renovation clear, costed and stress-free.

First name Last name
Energy-renovation advisor & author of the wendows guides
On the ground for over ten years, he has guided hundreds of Belgian households in choosing their windows, heating system and solar installation. He knows the real constraints of homes here — from Brussels’ older buildings to detached houses on the outskirts.
He writes the wendows guides with one principle: explain without overselling, cost things honestly and always set the advice in the context of the home and the available grants.
