Glassman, I probably didn't get the cheapest deal, but I wasn't trying to. A girl (woman really) came, in a suit, sat down showed me what I could do, made a load of sensible suggestions about my conservatory and just told me what I needed to know. She had that womans design thing "have you thought of so and so, why don't you do it like this it'll look better" which really helped. It was much better designed with her input
She measured up and gave me a price. I got another big name in and the first lot were cheaper so I went with them, a surveyor came and measured properly later and that was that. The local guy who quoted seemed a bit clueless and was definitely a bit stroppy
They just did not hassle me and did a very good job, everything works well and they did very little damage. I couldn't fault them and believe me I was expecting to. The last experience put me off for 20 odd years, so I was sensitive about pressure selling to say the least
I'm not saying the Nationals are necessarily better than local firms, they are certainly more expensive, but my own experience has been positive so far
