After my son had problems locking and unlocking his UPVC door. I rang S Fretwell and Sons, who advised us over the phone what the issue was. On the day we had arranged the visit, they rang to say they were on their way. I am really pleased with the repair work carried out, as the door is now better than when it was installed. They also charged what they had quoted with no additional charges. We would have no hesitation in contacting them again if we had any further needs, and would definitely recommend their services.
