Hi Andy,

As a professional in the industry, I am all too aware of the
complexities and problems when dealing with companies who are not
providing an 'All inclusive Manufacturers Warranty'. Essentially the
most frequently offered form of "Guarantee" is an insurance backed
version. This means that, apart from the get out clauses, that you'll
probably end up dealing with a company completely different to that
which carried out the installation i.e. three quotes and the least
expensive one gets the job!

I realise that it's a bit late now, but many Insurance Backed
Guarantees include a clause that indicates Leaks are expected in a
conservatory and therefore are not covered.

Personally, I would consider legal action or at the very least getting
trading standards involved. You may also might consider checking the
(if any) professional and impartial organisations that the installer is
registered with. These include the GGF, FENSA, The Conservatory
Association, The BBA, The BSI etc. Perhaps the installer may consider
more appropriate assistance with the intervention of one or more of the
above!

To anyone else considering a Conservatory, choose one that is properly
qualified, has had many years in the industry, manufactures its own
product (this does not mean assembles someone else's!), guarantees
its own work and product, and has at least registered with the GGF,
FENSA, BBA & BSI for some peace of mind.

Hope all goes well Andy, Good Luck
