We had a single glazed conservatory, which was freezing in winter & boiling in summer – we didn’t wish to replace with a white pvc one as this was out of character with our house. We found Hytek and Michael explained their offers and pricing. Unlike the usual “buy one, get one free” or “50% off” companies, Hytek’s pricing was fair & reasonable. Installation went exactly as planned, to the extent that friends didn’t even realise that the entire conservatory glass & roof had been replaced. The installation was so successful that we subsequently entirely removed the roof & door between the conservatory & rest of the house.. It is warm in window & cool in summer & we live in it most of the year! We have have a couple of minor problems since the replacement conservatory was installed; in both cases, the issues were promptly fixed, at no charge. Hytek is an exemplar, in an industry, littered with “cowboys” – I cannot recommend them too highly – quite simply a joy to deal with!
