Velux roof window installation
in Wavre
The capital of Walloon Brabant, Wavre mixes an old centre tucked into the Dyle valley with broad suburban districts built between 1960 and 1990. Opening up, fitting and weather-sealing roof windows, with a neat interior finish.

The context in Wavre
Why here in particular
What changes in Wavre is the context: brick terraced houses in the centre, detached villas on the outskirts, plenty of concrete-tile roofs laid in the 1970s. The valley floor stays damp for much of the year: north-facing slopes take moss faster than elsewhere and the bottom of the facades shows it.
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 Wavre
The questions we get asked most often before this kind of job.
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 need a permit?
Often not for a window in the plane of the roof, sometimes yes depending on the municipality and the area. We check beforehand, which saves a nasty surprise.
Which size to choose?
The width depends on the spacing between the rafters. We measure before ordering: that is what stops anyone butchering the roof timbers.
Do you come out to Wavre with no extra call-out charge?
Yes. Wavre is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
