Before the start of any works, we should estimate the condition of our windows and look at:

  • Presence of spots and fungus – both are the results of insects living in the wood;
  • Cracks and holes, that could have appeared because of insects or excessive moisture;
  • Presence of hidden defects and empties. These are revealed with the help of slight beating on the surface of the wood by screwdriver or other alike equipment.

Mechanical removal of old coatings is carried out by grinding wood surface with thin sand paper or grinder.  Thermal removal is the process of deleting an old layer of paint by using a special “burner” device.  Burnt varnish can be easily removed with putty knife.  Chemical method is removal of old layers by special chemical liquids.  It should be once applied and left for several minutes, then safely removed with the help of putty knife and thin sand paper

Covering the empties, rot and fungus removal

After an old coating has been removed it is time to work out cracks, empties and holes.  Even small holes in the window frame are a sign that something is wrong. The most possible reason is that the wooden material was attacked by pests. Over time, rotten fragments will become soft and may fall off and the wind will start to blow through these holes.

Rotten wood and fungus are most widely met in the bottom part of the frame – the place where excessive moisture is gathered after the hard rains and snowfalls.  If not seen at a first sight, then check their presence with the help of screwdriver, by giving slight blows on the surface of the frame.  Mild and questionable places should be thoroughly cleaned.  Wood hardener liquid should be than applied by brush and after it got dried, the wood putty should be put on such places.  Edges should be cleaned with sand paper.

The next step is to cover the wood with impregnating material, which will permit the same rot and fungus problems appear in future and let the wood “breathe”.  Paint should be applied as the closing step of wood frame renovation.  And finally, our skillful technicians will safely put the unit back.
