This is where the specialist's know-how is most apparent. If brand-new glass has been installed, the weight of the sash will have altered. The professional should compute the new weight and add or remove cause make sure the window runs with "finger-touch" ease.
5. Draught-Proofing Installation
Modern specialists set up discreet brush strips into the beads and meeting rails. This practically removes draughts and rattling without impacting the window's look.
