Installation of windows

The quality installation of windows, whether wooden, PVC, or aluminium, is of crucial importance. Regardless of whether you are replacing old windows or installing new ones, the connection between the frame and the wall must be well sealed to ensure and maintain the heat and sound insulation provided by the windows.


You can trust the window installation to our MIK professionals who are experienced in performing quality work in compliance with all technical requirements, thus ensuring long-term usage of your windows and a 10-year system guarantee.

  • MIK installers will deliver your order on time.
  • The foreman will keep you informed about the procedure and details during installation.
  • The installation team will protect the floor and other directly exposed areas where your windows will be removed/ installed.
  • The installation process begins with positioning the window within the wall opening - determining the right height, depth and angle of window installation using a laser measurement sensor and a spirit level.
  • The next phase will be fixing the frame into the wall opening and sealing it with the selected sealing material. Implementation of this phase will depend on whether you have chosen the traditional installation, ECO installation or MIK RAL installation.

The casement needs to be installed without mechanically damaging the casement or the window frame
, there should be no hindrances, and the casement should be correctly positioned to be easily opened and closed.
