We perform all repairs related to the exchange of old joinery or already installed PVC, ALU and wooden joinery. When installing the joinery, it is necessary to first remove the old joinery, so in such a process some damage is caused to the inside and outside of the wall, which, after installing the new joinery, is to be repaired as soon as possible, otherwise the polyurethane foam may deteriorate while affected by external conditions such as temperature and humidity. If the edges around the windows are not properly sealed, there is a possibility of water penetration, which can cause subsequent damage to the wall, and mould and fungus can appear in the places affected by moisture. We offer more processing options depending on your needs, functionality and aesthetic design. When processing, we use various materials such as classic plaster, autoclaved aerated concrete, styropor and styrodur. For all our works, in the final part of the work we set a glass-fibre mesh that prevents cracks caused by the difference of the material, as well as a flexible adhesive in two coats. When finishing the edges of the windows we trowel finish the surface and paint the skim coat in white colour or, upon request of the client, in the existing wall colour. We try to equalize the colours as much as possible, but often there is a difference in colour because the shade depends on the environment and on the influence of other factors such as smoke, moisture, mould and type of colour.
