"Dunders uPVC replaced our old windows and doors, offering great advice for our requirements without being pushy. They are friendly, their workmanship is excellent, reasonably priced, and they made sure everything was clean and tidy afterwards. I would 100% recommend their services."

"Finally, a tradesman who turns up on time, doesn’t charge the earth, cleans up, and goes out of his way to make sure things are completely done properly. Highly recommended!"

Dunders promptly addressed the issue with the patio doors within minutes, completing the work efficiently and leaving the workspace clean and tidy. Dunders were able to assess the door through a WhatsApp call, which allowed them to fully understand what was required. I appreciated their professionalism and expertise throughout the process. Would highly recommend.
