Stay Safe and Secure

Our uPVC window range is internally beaded as standard. This means that we  install and bead the glass from the inside for additional security.

Your windows come with a facility to lock them whilst slightly ajar. Always fully close your windows and and engage the multi point locks if you leave your home.

How to Care for Your Windows

We’ve put together the below checklist to provide you with a quick reference guide for what you should do and should not do to care for your home improvements and keep them working optimally.

How to Care for Your Windows

Care and Maintenance

With a minimal amount of care and maintenance your windows and doors will stay looking good and performing superbly for many years to come. Our products are easy to use and simple to care for and maintain.

Lubrication of Window Locks and Moving Parts

All moving mechanical parts require lubrication. Your windows and doors are no different. The hinges, locks and keep plates will benefit from a small application of light oil. We recommend lubrication of these parts once every six months. It is also vital to ensure that the hardware and groove that the hardware sits in is cleaned regularly using a soft brush or vacuum cleaner to remove any debris which may affect the operation of the window.

Adjustment of Friction Stayshow to care for your windows

A friction stay is a type of hinge that controls the opening of the window so that it stays open where you want it to. It won’t close under its own weight and should never been too difficult to open and close. This hinge is factory set, and after continued use it may become loose. Should this occur, you can use a small flat headed screwdriver to turn the brass screw which is located on the friction hinge clockwise. This will increase the amount of friction and tighten up its operation. If the window becomes too stiff, you can perform the reverse action and loosen this screw by turning it anti-clockwise. The same adjustment should be made to both hinges, either side of the window.


In certain circumstances if the surface of your frames is cold enough and there is enough moisture in the air, then condensation can occur. Due to advances in glazing technology, not only is it possible to experience condensation on the inside. Condensation may also form on the outside of the glass. This does not mean though that your windows are faulty. You can read more about the causes and how to combat condensation here.

Leaded Glass Units

We use natural lead for our stained and lead patterned units. It will remain shiny on the inside of the units, but any lead exposed to the air will oxidise. Oxidation consists of a film forming on the surface of the lead which consists of a layer of insoluable lead salts. These may vary in colour and on occasion a white deposit may form. This is not harmful and does not affect the function of the windows. It can be removed for aesthetic reasons if you wish. Use a mild detergent and pan cleaner, although you should take great care to avoid scratching the glass.

Cleaning Your Windows and Glass

White uPVC Windows

Under normal circumstances windows can be washed with diluted washing up liquid and warm water. Occasionally, where more stubborn stains build up, it may be necessary to use a non-abrasive liquid cleaner designed for uPVC. Apply the cleaner using a dry cloth, use sparingly in small circular motions, and then buff back to a shine.

Woodgrain, Colour Painted uPVC and Aluminium Windows

Use only diluted washing up liquid and warm water. Do not use any cleaning fluid on windows made from woodgrain, colour paint or aluminium profile.

Insulated Glass Units

You can clean the glass with any proprietary brand of glass cleaner, or warm water. The only exception to this is self or easy cleaning glass, which should only be cleaned with warm, soapy water.

We recommend that you clean both the inside and outside of the windows at least once every 6 months. Aluminium in coastal locations should be cleaned every 3 months. Do not use metal or abrasive cleaners, ammonia based cleaning fluids, or high pressure or steam cleaners on the frames or hardware or you will invalidate your guarantee.

You have the benefit of our ten year warranty on your windows and doors, and we are happy to attend to any problem you may encounter. Please do not personally attempt repairs to your windows and doors other than the general care explained above, as you may inadvertently invalidate your warranty.
