Installation and other services

Plastic window and door removal and installation

Plastic window and door removal

  • Before the actual removal of plastic windows and doors, the installation technicians shall make a window and hole size check.
  • Window and door removal is always carried out in a destructive manner by slitting the original window frame and its gradual removal by individual parts (unless otherwise agreed).
  • The removal starts by unhanging the leaves from the frames. Installers will either take them to a place predetermined by the Client (corridor, yard, etc.), or into a container or installation vehicle if disposal of the old windows is negotiated.
  • The next step is incision of the original window frame with a saw for wooden windows and an angle grinder for steel windows, in several points. The post is then cut out of those windows that have one. In case the customer insists on keeping the original frames, full account must be taken of significant damage to the reveal and more costly building-in by masons.
  • Incision of the frames is followed by levering the frame out of the reveal. This operation is carried out with a crowbar using a wooden block leaned against the reveal in order to minimise the reveal damage. Damage to the facade and reveal always depends directly on the condition of the adjacent masonry.
  • After removing the window frame from the reveal, the installers check the hole size, and adjust it as and if necessary. Then they clean up any remainders of rubble and dust from the hole. Installers sweep the demolition rubble (remainders of bricks, plaster, etc.) and take it to the place specified by the customer.
  • Since vehicles used for window installation are not designed for transporting loose waste, rubble removal is not part of old window removal (unless the contract specifies otherwise).
  • The hole is now ready for installation of new windows. If the customer prepares the hole on their own, it is necessary that they exactly observe the specified hole dimensions as agreed in the contract.

Installation of windows and doors

  • Clean the structural hole before the actual installation by removing coarse impurities and check the hole dimensions. The space around the windows to be foamed should not exceed 1-2 cm.
  • Check to see if the holes for turbo screws are pre-drilled. These holes are drilled approximately 15 cm from the corners, then at a distance of 70 cm from each other at the perimeter.
  • Fit the hole element frame roughly in the structural hole with wedges. Select the window placement depth according to the required depth of reveal, used sills or according to the original reveals.
  • Bring the frame into the horizontal position at the specified height and fix it with wedges (see the figure). Measure the verticality on one side first, then on the other. Recheck the measurements once more and inspect the frame placement by measuring both diagonals.

  • Anchor the frame of the window with steel anchors or turbo screws. Always anchor doors with turbo screws as close to the hinges as possible.
  • After the anchoring, recheck the horizontal and vertical position of the frame, alternatively, the flatness of individual sides (deformities by anchoring).
  • Put the leaves back into the frame, fitting the glass into the frame for fixed windows. To avoid deflection of the frame due to the action of expansion foam, use the plastic leading wedges along the perimeter of leaves. The wedges are then removed once the foam cures.
  • Wet the field joint and then fill the joint with expansion foam. We select the amount of expansion foam so that there is no need to trim it, if possible. If we are also performing the subsequent masonry works, the expansion foam is trimmed once it totally cures (in case of larger expansion). If we are not performing the subsequent masonry works, the foam is trimmed by the Client.
  • The window installation is followed by a check of adjustment and function.
  • Installers clean the installation roughly at its conclusion and use an industrial vacuum cleaner to vacuum all the coarse impurities from the frame and hardware (plaster, dust from bricks or chips generated by drilling the installation holes).
