We’ve had a problem with both sets of our french doors almost since fitting. Both sets allow noise from outside and one leaks. Aron diagnosed the problems immediately and how to fix them. Nothing was too much trouble for him and what a lovely man to work in our home. Friendly, chatty but above all a good, professional workman. Did an excellent job and cleaned up when he’d finished. Not a sound can be heard now and no more leaks! I would highly recommend Windowgeeks and Aron.
