Window lock change in plastic structures will definitely be required during intensive use. It is difficult to carry out the work on your own without experience and special tools. The best solution is to entrust your window lock to a specialist from our local London company. Any locking mechanism will gradually fail over time no matter the quality and price tag of the product. Moreover, it is possible to foresee a lock breakdown long before its appearance. Scheduled servicing of window locking devices will help to avoid more serious malfunctions and keep your home or office premises in London safe. Replacement of window fittings should be carried out in a timely manner to guarantee trouble-free operation of all system’s components. Otherwise, the holes for fastening mechanisms may loosen, other problems may arise. All this leads to an increase in the cost of repairs. The main signs of a malfunction are as follows:

  • It takes an effort to close or open the window;
  • Sealing is compromised – drafts occur, the room cools faster;
  • The lock handle is difficult to turn – at the same time the sash begins to fall off its hinges.

Lock replacement in all of the above cases should be carried out by an experienced locksmith. However, you can try it yourself to find out which elements are out of order. This will significantly reduce the time for changing faulty lock parts. It is thanks to the fittings that you can open the window, close it, set it for ventilation. All of the above tasks are implemented by a rotary mechanism. It is a set of movable heads – changing their position allows you to close and open the window structure. For example, when closed, all heads move to the top corner. Window fittings for plastic structures allow you to control mechanisms inside the frame. Main components:

  • Direct gear – allows the handle to move up and down;
  • A pair of angle-type gears – move the sash in the longitudinal direction;
  • “Scissors” – they hold the sash and connect it to the upper hinge.


It is simply impossible to fix most of the window lock problems on your own; to change the pivot mechanism and other elements, it is necessary to remove the sash from the hinges. It requires not only certain experience but also a non-standard tool, for example, L-shaped keys. Replacement of hardware in uPVC windows usually involves the installation of a new lock handle. Such work is relatively inexpensive and takes a minimum of time. Hinges fail a little less often; it is necessary to replace the axis of rotation of the entire mechanism. If you have a part with the same dimensions, there are no problems. Often, the fastener holes on the frame and the new mechanism simply do not match. In this case, our locksmiths, using a special template and a drill, carefully make new holes according to the size with a drill.

The replacement of window fittings should be entrusted to the specialists of our local London company. It is not recommended to do this on your own as you can damage the glass unit. We work with all types of window frames: uPVC, wooden and aluminium. An independent attempt to install a new mechanism can lead to damage to the glass unit and the need to replace it as a whole. Turning to London locksmiths, you can be sure of the high quality of services. Prices for the replacement of a window lock are set individually. You can rest assured knowing that we provide lock services at the most competitive rates in London and surrounding areas. The cost depends on the following factors:

  • The nature of the breakdown and its complexity. For example, replacing the window lock cylinders takes longer than installing a new handle;
  • Type of the lock and overall dimensions of the window opening;
  • The manufacturer of the fittings to be installed. The installation of some lock models requires additional work such as drilling new holes for fasteners.

Our specialists will drive out to any place in London free of charge if an agreement is made on the provision of services upon arrival. The price of the work is determined individually; the calculation of the cost is completely transparent. Replacing the window lock takes a minimum of time. You can get detailed information by calling our hotline or by leaving a request for a call back on this website.

I had a chance to deal with this company last Friday, I came home for lunch, but I could not get into the apartment, I opened one lock, and the second in no way, I could not turn the key at all. As a result, I found this company on the Internet and asked them to send a master to me in the evening. At the agreed time, the master was already waiting for me near the entrance, and after 15-20 minutes I was already in my apartment. It turned out to be neatly opened. I am glad that everything went without problems, quickly and relatively inexpensive

For the first time I had a chance to contact such a company, I stupidly slammed the door last Sunday, really, like a story in the movie, I jumped out into the store, and when I heard the door slam behind me I realized that the keys were in the apartment. I called this organization, they promised to send the master as soon as possible. And they did not disappoint, for less than an hour I waited for his arrival, a smart little man. He worked for about 10 minutes, slowly, and voila, the door is open.

An unpleasant situation occurred, the door to the apartment slammed, and the keys were left on the other side. I don’t keep a backup option from my neighbors, but my wife was on a business trip. The phone was with me, I found this company on the Internet and called. The master arrived very promptly. Within an hour I was there. He quickly opened the lock.

Had troubles opening my door lock once in a while. I decided to take care of the business before it gets worse. As I don't know much about locks, I called this company. The locksmith came to me in 20 minutes, checked the lock, and told me it needs cleaning. He finished the job in a few minutes. Must say I'm pleased with the level of service. They are somebody I can rely on. Definitely recommend them.
