Greenhouse repair

[whichonespink]

Afternoon NE PH'ers,

I have moved to new house with a greenhouse but the green house needs some work before i can get my price winning chilli's on the go. Lol.
Anybody know of anyone who does Greenhouse repairs in the Hartlepool/Teesside area. I have a couple of broken windows and the sliding door is pretty stuck. I have searched google which only turned up glaziers. Due to the way the windows are held in the aluminium frame via clips, i am not sure that this is their thing.

Anyone help or offer advise.

Thanks

Pink
