living on a busy street and often woken up for a loud rumble of the trucks or bikes passing, PVC double glazed windows was a priority for us before any other renovation and ADG was one very efficient company to respond quickly, come and see and lay the options for us. Absolutely flexible, reliable, very accurate. having to replace all the windows around made me ready for a long and messy process but meticulous work on installation merged fine in our day to day life without causing any disturbance and Craig's determination helped to shorten this time greatly and finish it off in just three days. it's an old house but the windows alone changed the whole lot of it - just pleasant atmosphere inside and no more gloom and nasty corners. good luck on your venture and wish i could see you again for doors. thanks guys - was very pleasant to have you at my place
