Absolutely shocking treatment from this company. Signed contract in June. They've charged nearly 4000 for front living room and bedroom windows. I've had to chase them until they finally arranged a date in September this year. They call to cancel the job stating their workman don't work weekends. Arranged a date two weeks later. At the point of installation their own workman informs me wondows aren't reinforced or bespoke in his opinion.
Told installers on this basis I don't want to go ahead. I've received offensive and abusive calls from their paralegal Tommy Evans who screamed and swore at

Dave & Paul have just completed my conservatory work. There was a little delay due to Covid, but the office kept me up to date at all times. The job is so lovely. I sit in there with my morning coffee looking at my garden. I have now ordered a new kitchen and expecting the work at the end of the month. I also told all my friends at church how they do a fabulous job.
