“Chiltern Home Improvements in Luton, Beds were recommended to us by a local estate agent in Amersham, Bucks and we had 14 UPVC windows installed with a new front door and polycarbonate conservatory roof in our semi in Amersham. The work was done to a very high standard, completed as promised on time and at a very competitive price. I would highly recommend them to anyone needing new double glazed windows and doors.”
