Highlights
"Our internal stained glass door got badly damaged. I took the door to Sharon to assess and she suggested some additions to the stained glass to add more strength. We are extremely pleased with the result and very grateful for the work that she did."
"I live in East Kent and bought an Edwardian Property that needed 20 plus windows to be replaced (period style double glazing + complicated due to shape of windows + period stained glass. After much googling with found the Knowles Glass Team. I am glad we did - the care / managing of emotion / time taken by both Sharon and Michael made us comfortable to proceed. No call / email / site visit was too much to give us comfort we found the right people. The work / quality of craftmanship speak for itself with complementary comments from neighbours. We have more work in the future and we will back,"
"We wanted to retain our stained glass in the front door but did not know it could be done. Our old door was 100 years old, so we did not expect it could. Then we found Knowles who were very professional and have completed the most amazing installation of the old glass….cleaned, sparkling and thoroughly renewed….into a substantial and robust new door. We are thrilled with the result. They were careful to carry out our wishes and the cost was reasonable. The new door has transformed our entrance from inside and out."
