Windows & Door Maintenance


Adjusting and cleaning uPVC windows and doors

Although replacement PVCu window and door products are predominately maintenance free, the following guidelines should ensure that you receive many years of trouble free service, and will help you with adjusting and cleaning uPVC windows and doors.


Due to normal operation and atmospheric conditions, the moving mechanical parts of the doors and windows may require lubrication.

Keep plates, locks and hinges of both windows and doors will benefit from a light application of oil/grease to the contact area of moving parts.

As a general rule, lubrication should be required once every 12 months depending on usage. Please use silicone spray, not WD40, as this can become tacky.

NB: Under no circumstances attempt to dismantle any components. If you require further assistance please contact us.

PVCu Frames – White

Under normal circumstances the washing down of window and door profiles with diluted washing up liquid and water will suffice. However, where more stubborn marks or a build up of atmospheric grime exist, a non-abrasive cream cleaner specially designed for PVCu profile should be used.

Apply the cleaner to the affected area using a dry clean cloth. Use sparingly applying gentle pressure in small circular motions. Buff back to a shine.

PVCu Frames – Woodgrain

To clean woodgrain frames use only diluted washing up liquid and water.

NB: Under no circumstances use any other cleaner than those advised by your supplier. Other cleaners not recommended may have an adverse effect on the surface finish of your windows.

Friction Stay Adjustment

The majority of opening windows are fitted with a friction stay, which is a type of hinge that controls the opening of the window itself. This is factory set so that the window neither closes under its own weight or is overly difficult to open and close. After a period of time, the friction pad may wear making the opener loose in operation. To adjust you can take a small bladed screwdriver and turn the screw by half a turn clockwise. The same adjustment should be made equally to each pair of hinges. If this adjustment is insufficient then carry on turning the screw in half turn increments until the desired amount of friction is achieved. If the opener is very stiff in operation, turn the screw by a quarter turn increments anticlockwise until desired result is achieved. NB: If you have difficulty in making the above adjustment, please contact us for guidance.

To adjust the hinge first remove bottom cap. To raise the door sash rotate the vertical adjustment screw clockwise, ensure that all the other hinges are adjusted equally. If you need to lower the door sash, rotate the vertical adjustment screw anti clockwise, ensure that all the other hinges are adjusted equally.

Lateral Door Hinge Adjustment

To adjust this hinge first remove the side cover caps. Next rotate the lateral adjustment drives in the direction required, ensure that each pair of alignment marks are at the same point.

It is not recommended to fully adjust one adjuster only or one hinge only, adjustments should be made gradually aligning each pair of marks on each hinge until desired adjustment achieved.
