The context in Grez-Doiceau
Why here in particular
A rural municipality in the Train valley, Grez-Doiceau keeps a scattered pattern of housing between hamlets, square farmsteads and recent builds. In practice, large converted farm volumes pile up long roof valleys, endless fascias and old roof timbers that have rarely been treated.
A roof window that leaks is almost never the window: it is the flashing. A sealing kit that does not match the type of roof covering, and water gets through the first winter that comes.

Frequently asked questions
Velux roof window installation in Grez-Doiceau
The questions we get asked most often before this kind of job.
And condensation?
It comes from a lack of ventilation, not from the window. A reveal cut square at the top and sloped at the bottom lets air circulate against the glazing.
Do you replace an existing roof window?
Yes, and it is often half a day: the new frame takes over the existing opening when the dimensions match.
Do you fit blinds and shutters?
Yes, at the same time. That is the right moment: the joint is open and the feed is run cleanly.
Do you come out to Grez-Doiceau with no extra call-out charge?
Yes. Grez-Doiceau is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
