Wind Turbine Maintenance – HLS Wind provide a comprehensive onshore maintenance programme for wind turbines, ensuring they are operating at their optimum efficiency.

Mastic Sealants and Painting:

HLS Wind utilise rope access techniques to provide a mastic sealing maintenance service, replacing old / worn mastic both internally and externally and also providing a mastic sealing service during wind turbine construction.

We also provide a thorough external painting service, using specialist weather proof painting systems we are able to abseil the length of the turbines (including the blades) to ‘touch up’ weathered external areas, re paint the entire turbine and provide painting during the construction process; always ensuring that the wind turbine looks as aesthetically pleasing in the landscape as possible.
