Wooden balcony algae treatment in Risskov
A grey, slippery, and dried-out wooden balcony was restored to a clean, fresh, and safe condition.
A wooden balcony and roof terrace of approx. 20 m² (approx. 14-28 m²) in Risskov was heavily covered in algae and bleached grey by the sun. Øens HåndværkerCentral gently treated and cleaned the wood without pressure washing, sanding or replacing it. The balcony is now clean, fresh, well maintained and safe to walk on again. The work took 1-2 days.

The task
The balcony had heavy algae growth and sun bleaching. Large areas of wood were grey, dark and slippery, making it both unappealing and unsafe to walk on. The customer wanted to restore the surface and make the balcony usable again without sanding or replacement.
The solution
- Targeted algae treatment with a special product for outdoor wood
- Gentle cleaning and rinsing without the use of high-pressure washing
- Careful treatment to protect the wood, without sanding or replacement
- The entire job completed in 1-2 days by Øens HåndværkerCentral
The result
The balcony looked clean and fresh again. The grey, slippery wood regained its colour and life, and the surface became safe to walk on. The customer was left with a well-maintained wooden balcony that looked almost new, without having to do any of the work themselves.
Vi fik renset og algebehandlet vores træaltan, og resultatet er helt i top. Den ser frisk og velholdt ud igen. Hele processen var nem, hurtig og professionel, og det føltes som en luksus ikke at skulle tænke på noget selv. Kæmpe anbefaling herfra!Jette H., Risskov
