Was absolutely not interested in helping me as replacing one window "wasn't worth his time!"

Just had a very large job of Double Glazing replacement completed. Andrew visited the house for assessment and pricing which was very competitive.
Shona dealt with all phone enquiries, emails and invoicing. There were 19 units in total including 6 conservatory panels 6ft x 4ft. Carl and Carl fitted the lot over a couple of days. They were very professional and approachable and worked to the highest standards. The job was completed thoroughly with no mess.The windows were left in immaculate condition and I can not praise them enough. A very approachable company carrying out work to the highest
