Our upvc front door had stopped working and the locks would not engage so my husband today stripped it and replaced the gearbox (with help from a lock shop in town).
Its working well now, but you can open the door from outside without a key (unless its locked) and from inside you need to...
Thanks for the help. Doesn't sound too expensive, and neither I nor husband have a clue with plumbing/heating systems.. so a heating engineer it will be.
Thanks again
Wondering if anyone knows whats causing this/how to fix or how much it would cost for someone to do it for us:
since we had a new kitchen fitted in may last year we have found that whenever we have the hot water turned on the radiators heat up. This is not at all controlled by the thermostat...
