I took my son, a carpenter joiner, to Oaktree’s factory in Wiltshire to check the quality of the material and workmanship. He confirmed all was of good quality. Subsequently cottage style windows and doors were ordered. Martin and Kevin visited site and did the final measurements. Oaktree delivered exzctly on the due date and the windows were fitted by my son. He remarked on the quality and also that the dimensions were precise and fitted perfectly. The windows look great and it is heartwarming to hear every tradesman working on the refurbisment of the house on the quality of the doors and windows regardless of their particular trade. I have no hesitation in recommending Oaktree.
