Velux roof window installation
in Lasne
Opening up, fitting and sealing roof windows, with a careful interior finish. We do this in Lasne from our base in Walloon Brabant, always with a site visit to price the work before anything is committed.
The context in Lasne
Why here in particular
Isolated properties pile up square metres of roof, plus outbuildings that stay forgotten until the first leak. So we adapt the equipment and the method rather than running a standard protocol.
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 Lasne
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 Lasne with no extra call-out charge?
Yes. Lasne is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.

While we are on site
Combining two jobs in one visit brings the invoice down. We suggest it when it makes sense, never to pad the quote.
