"Marcin was efficient, punctual, very polite and a hard worker. He replaced two faulty sash cords and adjusted the weights in both sides of the sash windows. He brought his own dust sheets and vacuum cleaner and left the room cleaner than when he arrived! I have already recommended him to friends and would not hesitate to use him again."
"Marcin is reliable, trustworthy and easy to work with. He did an excellent job repairing a sah window. Was clean tidy and respectful and would highly recommend"
