I need someone to install overhead door closers properly

Hi There,

I have a five bedroom house in Stamford Hill that I manage. All bedroom doors have to have overhead self closers for H&S reasons. The landlord fitted some so badly that the poor tenants have to push really really hard to open their bedroom doors. I need someone with experience to refit them in the right place so that they work properly. Any suggestions?

Cheers,
