Summer Sail UPVC Fail: The Alignment Edition

As we get much warmer weather across the summer months, the hot days are certainly more welcome. Our grass, our plants, our way of living all take positive impacts from the warmer weather. However, our UPVC windows and doors tend to have a negative effect which can often turn a nice warm steady day into a panic day.

As many of us are aware, UPVC is manufactured of tough plastic composites and nearly every home or business in the UK is often secured by UPVC doors and windows. UPVC is usually a light and durable solution to secure our homes and businesses. UPVC is also a cheaper solution to wooden composite doors and often operates much smoother, however it doesn’t come without its downfalls.

UPVC doors & windows expanding in heat

One of the major problems with UPVC is that it is made of plastic, which means that heat has a massive impact on what the UPVC does and how it reacts. An interesting fact about UPVC is that it can expand up to 2.4 centimetres in just over 40 degree heat. We don’t get 40 degree heat in the UK, but if we did not many UPVC doors would be opening or closing correctly as they would have expanded themselves out of alignment.

This happens on a much lower scale even at 23 degrees. UPVC doors and windows are lined up when fitted so that they shut firmly but smoothly, the fitting to make the door smooth only allows for fine margins so when the door opens and closes everything lined up in the exact place it needs to be for the locking points to engage with the strike plate holes. Once the door slowly starts moving out of alignment over time, you will notice the handle will start becoming stiff to lift or the door is catching and hitting off the frame itself. The longer the door is left misaligned, the stiffer the handle becomes to lift.

How to repair misaligned UPVC doors or windows?

To realign a UPVC door it’s quite a quick repair taking no more than 5-10 minutes, however the longer the door is left misaligned the more damage the mechanism will start taking and eventually become broken, either locked shut and unable to open or open but unable to lock shut. A mechanism replacement will cost a lot more than a quick, simple UPVC door or window alignment.

Your Secure Locksmiths are experts in and around Nottingham at UPVC door alignments and it would be highly recommended to book an accredited engineer if your door has shown any signs of dropping, become stiff or hitting/scrapping off any part of the door or frame itself.

Service Time: The Smooth Locking Edition

The Autumn months and darker nights are back here with us, so we should use the time to prep for the cold and wet days coming ahead.

Locking systems work a lot smoother when they have been lubricated. Servicing a locking system is a very easy and common thing to do it just requires a small amount of lubricant spraying into the body of the lock itself and then the lock to be worked two or three times to allow the lubricant to spread round and work itself in. Using a lubricant on a lock allows the lock to work its internal parts without any resistance or stickiness, in turn, making the locking experience much smoother. The other benefits of servicing locks are to prolong the life of the locking system and to keep the lock weather resistant. Don’t forget the door hinges!

What lubricant should I use?

Your Secure Locksmiths recommend either a liquid oil based spray with PTFE in such as 3 in 1 or wd40(with PTFE) or a graphite powder.
If you have an old locking system on a UPVC door then a spray oil with PTFE is advised and if you have a wooden door with a lock in then graphite powder is advised as liquid based oil will soak into the wood.

How often should I service my lock?

Your Secure Locksmiths recommends servicing your locking systems every season change or 4x per year especially if you live near a costal town or seaside resort.

Servicing also applies to UPVC window mechanisms. Windows are made up of 3 different hardware and locking parts:

  • The Hinges
  • The handle
  • The Mechanism

Simply spray all the components with liquid PTFE based lubricant and operate 2 to 3 times to allow the lubricant to soak into the smaller restricted parts.

Your Secure Locksmiths can offer a service plan specifically for your property domestic or commercial. If you’re unsure how to service your UPVC door mechanism yourself simply give us a call and we will take care of the rest.

It is also a really good idea to service your manual car door lock often found behind a key cap on the newer models. Over 95% of cars have a manual override. The manual override will be required if your battery on the car or in the fob goes completely dead in which case your manual key blade will get you into the vehicle and from there you can pop the bonnet and jump start the car. Simply attach the long spray nozzle that comes with your can of oil place the tip into the keyhole and spray. Once the oils been sprayed inside of the lock simply pull out the nozzle insert the key and turn 2-3 times. Remove the key place back on the key cap if it has one and leave for 3 months and repeat.

Before servicing any parts still under warranty please seek manufactures or the installers terms and conditions so you don’t end up voiding your warranty.
