Safe Style have been out to adjust this door 2 times already (less than 12 months) and are due again, however they cant/wont come for 3 weeks , and ive been waiting for 8 weeks in total now.

I'm more than capable of sorting this , just cant seem to work out what adjusts what??????????

i have a major draft around the top of the door, and it isnt sealing against the rubber seals , hence the draft.

Any help or pointers would be much appreciated.

If it's a glazed door and the side opposite the hinges is sagging downwards, try a quick google for "toeing and heeling" a door. May cure your repetitive problem.

cheers ...... for the help
the problem is its not out of square, its just not tight against the frame.

Back door fitted by me , no drafts , no leaks , no problems
front door fitted by safestyle , always drafty, always moving ,,,
Lesson learn't , the two safestyle fitters where useless as is there after sale service
