I just wanted to know who would I get to fix our front door, it was fitted over 5 years ago and has gradually got harder to close. It's wood look, is that PVC?, I'm not sure, anyway its one that has the 5 lock system and it is impossible to lock and really difficult to shut all I need to find is someone that will fix it. It looks like that its off line, but my porblem is do I need to contact a locksmith or a company that fits these doors? and if someone can recommend a company that would be great. Thanks
