Most frequent questions and answers

This is dependant on multiple things, Such as, how easy it is to access, what size it is and what type of roof covering you have. All replacements, liek new installations, will be subject to a quotation based on each individual project.

Thats not usually an issue, most skylights are manufactured to similar sizes, we would have to check your current skylight ofcourse.

Leaking velux usually can be fixed, it depends on where it is leaking though. If it is leaking around the sash, more than likely the frame may be too damaged to repair. If it is leaking around the window (flashing), its possible it could be repaired.
