We have few maintenance instructions that will help you keep your windows and doors as good as new for the foreseeable future

Glass Cleaning:

Since the glass tends to get scratches over time, it can be taken care by using a glass cleaner and soft cloth.


On a yearly basis, remove the dirt and debris from the moving parts. You can lightly oil the moving parts with simple machine oil. Do not use metal polish or harsh cleaning products.

Outer Frame & Sash Upkeep

Use a soft cloth to clean the internal and external surfaces of the frame to remove any grime or dust. Clean with a mild liquid detergent solution and rinse with water to remove any stubborn marks.

Hardware Maintenance:

All Lock Types
The key-way, latch and keeps should be kept free from dirt, debris and obstruction at all times.

Multi-point Locks
On an annual basis, generously apply a smear of petroleum jelly or grease to each side of each additional hook or bolt. This will help in the smooth functioning of the lock.

Clean and lightly grease the track surface annually with petroleum jelly.
