hi all, just came across this website and it seems very useful. I am having a big problem with the fitting of my conservatory. The project is beng undertaken by a large reputable company but they are making major mistakes and I am far from happy. I will initally discuss the main areas of my concerns and maybe someone can advise me:

my first question is this: the dwarf wall was built at a height of 670mm as per the plans. however when the fitter came to fit the frames he said the builders should have only built to 600mm so he took off a course of bricks. he also sawed through the top of the interior thermalite wall to make the interior and exterior dwarf wall level. he has put the frames on and the roof is in place but i have noticed that under the sill all round the outside there is a gap of 1inch between the dwarf wall and the frames. this gap has pieces of small block wood to pack the gap in places but in the majority it is just an air gap. I asked the fitter about this gap just in passing and he said it would be filled with foam. I am a bit worried as I thought the frame should be sat directly on the wall, not with such a big gap. I am worried that they have screwed up somewhere and are now trying to make cover their mistakes? any ideas?? thanks in advance.

i've posted some pics here DIYnot > Network

i am hoping someone can direct me and tell me exactly what i need to tell the installers when i complain as i think he will try and say it is acceptable to just fill the gap with mortar.

thanks again
