Glotech are a company who provide excellent service in an old fashioned strain I thought had disappeared. Not only do they work to very high professional standards (I was fortunate enough to have senior member of the team), their ongoing support is also excellent. They will call, as a matter of routine, to keep the customer appraised of the situation regarding spare parts and time frames. I had quite a difficult time with an especially unusual and somewhat challenging job. After paying the initial fee Glotech worked on my behalf and following the first visit by pursuing parts and keeping in touch. There was no more to ay and they were keen as mustard to complete the work. In summary professional and reliable to the last and highly recommended.
