    The house was built 9 years ago, with a skylight in the middle with 10 double glazed units, 5 each side, 2 of which open on each side. Fantastic.

    About 4 years ago, the seal went on one, with the usual condensation problems, fast forward to today, I now have 6 gone.

    I thought it must have been me when cleaning the outside with a long pole squeegee, but this summer our heat alarm went off. I realised that the temp in the rooflight must have been pretty excessive and I think this is what has buggered the seals.

    There's plenty of companies that claim to be able to repair units, but before I see if any one can do it off a set of ginourmous stepladders, I wondered if anyone has had any experience with these repair bods?

    All help gratefully received,

    I ‘repaired’ one years ago, by drilling a couple of small holes in the outer glass pane with a tile drill. It did get rid of condensation, but the window was left streaky on the inside, and it makes the u value even worse. In my opinion, it’s not worth paying for that result. The labour involved is similar to replacing the DG unit (ie. the glass), assuming standard UPVC frames, and new DG is generally much enhanced over old stuff. Old units are usually centre pane U=2.7 with an aluminium spacer(!), and you can get considerably better U=1.1 with a warm edge quite easily now.

    Looks like this ought to be covered by the 10-yr guarantee...


    "During years three to ten of the cover, the warranty protects against a range of structural defects and for issues with items such as the double-glazing (...) "

    My previous house had Velux roof lights that failed just outside the warranty period of 10 years. Velux wanted an arm and a leg to replace so got replacement DG units from glass merchant and installed them myself. They were dead easy to do as the sash was removable internally. Depends on how your lights are constructed but to have failed so soon is a warranty job I reckon.

    Best to change design as destined to fail,again surely

    Well thank you all.

    Didn't get a 10 year warranty like NHBC, but fantastic builder and great architect through whom I think we have cover. However, I don't think it's anyone's fault and both builder and architect risked a great deal in building a non standard house to our specs, for which we are very grateful. Architect now retired, roof light manufacturer gone out of business and as Tony states "Best to change design as destined to fail,again surely".

    So drilling a few holes might be a mid term solution until I come up with a long term one. Simply replacing the lights with new DG units myself with an overheat opening mechanism sound best, but perhaps beyond my electronic knowledge (battery, switch, buzzer is about as far as I go).

    We had a problem after 2 years with wet room waste leak and swelling/corrosion of underfloor heating ply and heat transfer plates. Such a tricky job to replace that I did it myself, with underfloor heating pipes stuck to the wall whilst I replaced the wet room drain style gulley with a round one. I was happy to absorb the costs and did a better job than one could expect from a busy builder and his not so good plumber coming back on site and maybe making things worse (by cutting and rejoining the heating pipes under the floor, for instance).

    Apart from the above, the house, made of wood, has maybe moved 3mm in a couple of places and has proved to be exceptionally brilliant, so I'm happy to take a couple of knockss on the chin.

    Let it be said that this forum and members went a good way to giving us the confidence to ask for and build what WE wanted. Lucky us.

    Not nit-picking, but the record needs setting straight for future visitors to this thread...

    You get the warranty de facto (or rather de jure) - it is the law (Consumer Code, introduced in 2010).

    which starts “All new homes in the UK are covered by a 10-year home warranty and insurance guarantee.” This is plainly wrong; hands-on self builds usually don't have this cover.

    That warranty is very limited, basically major structural problems only after the first two years and then you have to fight your corner

    Indeed, so I suggest you post a clear statement that you misunderstood the situation and misstated the position. AS Ed says, that page is wrong - it does not apply to all new houses. Plus since it was only apparently introduced this year, it wouldn't apply to Dickster's house even if he had bought it from a builder who has signed up to the code.

    PS note that the entire site with further information about the code is simply no there, so the whole thing could be smoke and mirrors for all I know. Also note that the consumer code appears not to be law - it is a matter of contract. And probably cigars and brandy in darkened rooms.
