The questions we hear most often
Is the quote really free?
Yes, 100%. The advice, the technical visit and the priced quote are entirely free and without obligation — you pay nothing until you have accepted a proposal.
How quickly will I be contacted?
A dedicated adviser calls you back within 48 working hours of sending the form. For an urgent request, call us directly on 067 21 04 02, Monday to Friday from 8am to 6pm.
Is the home visit charged?
No. The visit and the on-site survey are free, anywhere in Belgium. It’s the chance to measure precisely and refine the estimate, grants included.
Can I request several services at once?
Of course — that’s the whole point of Wendows. Tick every service you’re interested in (windows, solar, battery, heat pump, insulation) and a single point of contact coordinates your entire project.
Can I attach my plans or photos?
Yes — use the “Your documents” area of the form to drop in your plans, photos or existing quotes (PDF, JPG or PNG, 10 MB max per file). You can also send them by e-mail to hello@wendows.be. It helps us prepare a more accurate estimate.
