“I can't say enough good things about Double Glazing Doctor. From start to finish, the service was excellent. Mark was professional, knowledgeable, and worked with incredible efficiency. It's rare to find a company that is so reliable and quick. My new window looks perfect. Thanks again..”
James Thompson
“I’ve worked with Mark twice now and recommended him to others. He’s brilliant at what he does. He’s replaced glazed panels before, and he’s just saved me so much stress by fixing the hinges on a large window panel that had completely come away. Use him, he’s ace!”
Emma Richardson
“Excellent from start to finish. Clear pricing, good telephone support, texts to confirm appointments, punctual, efficient, courteous.”
David Lloyd
“We had a window which wouldn't close due to a broken bottom hinge and window handles also needed replacing. Mark was brilliant, managing to squeeze us in the next day, arriving promptly and completing the work tidily and quickly. Would absolutely recommend”
