    I was introduced to Optional Maintenance after they won the contract to replace some aging air conditioning units around the Ronseal site.

    Mark along with his team of engineers carried out the installation in a professional manner, working to an agreed time scale and limiting disruption to a minimum.

    All the engineers were punctual and extremely courteous to all Ronseal staff during the installation period. Ronseal Ltd have now asked Optional Maintenance to carry out the periodic maintenance to all air conditioning plant on site.
