Gympie glazier fits Fraser Island lighthouse with new windows

A MAJOR renovation of Fraser Island's Sandy Cape lighthouse has drawn on the expertise of glazier Michael Harch, of Gympie Glazing Works.

Mr Harch has been joined by his wife and business partner Leisa in fitting out the lighthouse with new windows.

The project was finished Monday after five "non-stop" days.

Renovations on the lighthouse have been taking place during the past 10 weeks.

"The whole lighthouse has been sandblasted inside and out and repainted," Mr Harch said.

"Part of the process was the glass and that's where we came in."

Mr Harch and his wife stayed on site during the five days in the lighthousekeeper's accommodation.

"The biggest challenge was making sure it all fit to keep it 100% watertight," Mr Harch said.

Glass 8mm thick was used in the refit and Mr Harch said 15 flights of stairs were a challenge.

The lighthouse is the Gympie business's quirkiest project to date.

"We did replace the windows in the town clock, but that does not compare to a lighthouse," Mr Harch said.

The lighthouse is perched on the most northern point of Fraser Island.

Now fully automated and solar powered, every 10 seconds the lighthouse emits a flash of light that can be seen up to 39km out to sea.
