Maintaining Your PVCU Windows and Doors

Installing new uPVC windows and doors is a great way to improve the appearance of your home whilst saving money on energy bills at the same time and should be seen as a long term investment on your property.

Naturally, after improving your home with new windows and/or doors, you will want to keep them functioning properly and looking their best.

Luckily, uPVC windows require only very basic maintenance procedures to ensure you get the most out of them, unlike traditional timber frames that require ongoing TLC such as painting and treating on a regular basis.

Generally, looking after your uPVC windows and doors falls into three simple categories – cleaning, lubrication of hardware and checking the seals and gaskets are correctly positioned. Each of these procedure should be carried out on an occasional basis and below we give you some helpful tips.



A soft cloth and warm soapy water, or preferably a good quality glass cleaner, is more than sufficient to remove any dirt and marks from glass and glazing surfaces. We recommend using gloves and removing all hand and wrist jewellery before cleaning any glass to prevent scratches that could occur on contact.

uPVC Frames

Looking after the frames of any of our uPVC products requires a regular clean with a non abrasive soapy solution, quality washing up liquid works great for this. For really stubborn marks, grime or dirt, there are intense cream cleaners available in most supermarkets. We do not recommend you steam clean your uPVC frames, and you should NEVER use abrasive cleaning solutions as this could damage them.

Gaskets and Seals

When cleaning your windows or doors, check the seals and gaskets are correctly in place and no dents or breaks in the seal occur when the window or door is closed. Clearing any debris you see and wiping down the seals with a non-abrasive solution will also help keep the seals damage free.


Windows, Doors and Internal Mechanisms

A window or doors internal mechanisms also need to be kept in working order to ensure you maximise the life of them. All of the hinges and locking points should be kept clear of dirt and debris and every 3 months or so, apply an oil based lubricant to all hinges and locking mechanisms.

Sliding Patio Doors

We advise against lubricating the actual track of the sliding door as this can be dangerous. But check regularly for debris such as leaves that get caught in the track, removing as required. Make sure the locking mechanism and seals are correctly maintained as explained above.
