Can’t fault ADH Installations. Great service and a high quality installation completed quickly and efficiently. I had a competitor to ADH Installations put in double glazed sashes to the front of my house in October last year. We have had problems ever since with the works only completed in the last few days. Anthony at ADH installed better quality sashes in my new rear extension plus doors with parallel borrowed lights in a fraction of the time than his competitors and at a better price! I highly recommend ADH Installations!
