Advice & customer relations
Your first contact. The advice team analyses your need, visits your home, prices the project and prepares your grant files — no jargon, no sales pressure.
Request advice Our team
One team, five trades, a single project: yours
Behind wendows there are no subcontractors strung end to end, but one integrated team: advice, engineering office, installation, solar, heating and after-sales. All Belgian, all coordinated around your renovation.

One team, five trades
The skills that usually cost you five companies
Renovating often means juggling a carpenter, an electrician, a heating engineer and a grants coordinator. At wendows, these trades work in the same team, on the same project.
In practice: your advisor talks every day with the engineering office and the site managers. When we recommend window frames, solar or a heat pump, it is the same team that will install it and then follow up.
“We don’t pass the buck between trades: we’re all in the same room.”
The result: fewer middlemen, a schedule that holds, and one person who knows your project from the first call to handover of the worksite.
