hey guys

I purchased a new build last year with 2 velux windows on the top floor. When it rains heavy they leak through the handle but only when it hammers it down. Ive had the window fitters out 3 times but they can't seem to see where its leaking. I've decided to take a look myself i think I can see where waters getting in but I don't have any experience with windows at all so looking for any ones advice. ive posted some pictures below excuse the poor quality it was quite awkward [IMG]undefined[/IMG]

thanks

Tell builder : get someone competent in to fix it, or I get an independent in to fix it, and then bill you (and if need be, take you to court to get the bill paid) for the expense of doing so.

They've had 3 chances. You've been reasonable.

Have you measured the pitch of the roof? Velux require 15 degree pitch minimum. Just having an extension drawn up and it's a big factor apparently.

I'd advise contacting NHBC, this is exactly what your Buildmark policy is for. If they agree it's not right, they'll instruct the builder to fix it. If it's still not right, NHBC will either get it fixed for you, or pay you to get it fixed.

That avoids you paying someone else upfront and running the risk of not getting your money back.

Can’t tell myself from the pics but has it got the flashing kit installed?

^ as above. Can't see a flashing kit. Pitch is an easy fix with angle adaptors that won't involve tearing the roof apart.

NHBC.

Third party glazer for quote or advice. Off the record won't cost. For example a free quote from a glazer saying you're thinking of replacing it and saying why. Then ask your questions. Officially you'll have to pay a surveyor or glazer if you want a report. You then take said report to NHBC and provided you meet their criteria for claim then you claim.

Has the house builder finished all the plots? If their around on Phase 2 or something it's easier to approach the builder directly and say yes two years is up but would they consider it because it's their error etc.

Who is the house builder? Have you tried explaining your plight to the customer services department? It sounds like you have if three visits have been made. Kick it up to their head office if that's the case.


Some ideas here on self-diagnosis:

Isn't it a pan flashed skylight, which doesn't require a flashing kit?

That velux looks like it isn’t installed with the correct gaps around the flashing, you should have about 80mm at the top of the window, this could cause water to bounce over the top and through the vent, it may also cause water to track back up under the tiles but this is less likely give the drop stops on the flashing.

Have a look on their website for the I instructions specific to that window and check the gaps around the edge first.

Is it coming around the frame into the vent or coming through the vent because the first option would indicate the felt isn’t sealed properly against the window frame.

I can't tell from the pics but I thought they stood out from the roof more but I'm no expert

the flashing kit appears to be installed, otherwise it wouldn't have its hood installed.

You can install them recessed or proud depending on tile type and designers intent.

Just be aware that most NHBC claims have clauses now... such as min cost and water ingress before they will step in for roof work.

The hood looks ok, so either its the angle or the sealant around (which is the most common as shoddy work they tend to seal around the protective film which lifts)

These windows do not need sealant, if they have used sealant - they have fudged it
