Sliding door supplier recommendation?

[pete]

We're in the market for some sliding doors (2-3 to begin with, equivalent to a double-entry once fully retracted) at one of our sites to make it more accessible.

 

Standard door with sensor/button/reader options, out-of-hours lock, fire alarm integration in an appropriate colour, nothing too fancy.

 

Finding a provider (we're based in Lincolnshire) who can survey, provide a quote and organise installation in a timely manner is proving a little frustrating.

 

Who have your schools used that were good (hardware, installation, product knowledge, responsiveness)? Could you quiz your estates/site manager please.

 

cheers
