GBM are now back to work. Working to strict rules along with Government guidelines.

We are now entering many homes each day so for your own safety and ours we are adhering to strict distancing rules. Look on our COVID 19 page for more details.



GBM Door and Window Repair Specialists is a small company specialising in the repair and mantenance of all types of doors and windows and locks. Listed on the the contents page are details of all the work we cover. Basically any problems with your Doors and Windows GBM can sort them out.


We do not fit new windows and doors so unlike other so called repair companies we will not be trying to sell you new Double Glazing by condemning what you have as beyond repair.


A favorite is to tell you a lock or part is now obsolete this is common in the Double Glazing Industry but does not mean a similar lock , hinge , handle cannot be fitted in its place.


Before you look for quotes for replacement windows please contact GBM for a free quote to repair.
