UPVC Door Lock Repairs

When dealing with security, locks are often the most common methods to control access and entry. There are locks affixed to doors almost everywhere we go, and normally we encounter numerous types of locks and mechanisms. Some houses may have the standard rim cylinder locks and night latches, while others have mortice locks and cylinder locks. For larger properties or those involved in commercial activities, it is often common to have access control systems such as smart locks similar to the key card locks seen in hotels. For tenanted properties and offices, it’s common for landlords and managers to have master key suites or restricted access systems customized to the authority of each person working in their premises.

Aside from their purpose, another factor which causes locks to differ is the material or build of the door or entryway itself. There are different types of locks for gates, garages, patio doors, windows, and other openings and entryways in the property because they may be made of a different material. 

UPVC Doors and Windows

Certain types of doors require specific mechanisms to fit locks into it. One of these is the Unplasticized Polyvinyl Chloride, more commonly known as UPVC. This material is a durable, low-maintenance material often used for doors and window frames. You can commonly see it as the all-white frame lining glazed doors and windows.

Doors and windows made from UPVC often require a specific mechanism known as a multipoint lock. These are often mechanisms embedded into the frame of the door to connect the handle and the cylinder lock. In addition to maintaining these mechanisms, UPVC locks also need to have durable cylinder locks, with the most common being euro cylinders. 

As specialists in all UPVC mechanisms, D&M Locksmiths guarantees first-class service for all UPVC-related repairs. If you’re having an issue with the locking mechanism on your door, it is advised to get the issue fixed as soon as possible. These conditions on UPVC doors will eventually lead to a door that’s jammed closed and unable to be opened with the key, which might leave you locked outside of your home.

Our specialist locksmiths have in-depth experiences handling both common and more unusual issues when it comes to UPVC doors. We can fit, repair, and replace all kinds of UPVC doors for both front and back doors, as well as fit locks into UPVC windows. Numerous kinds of issues can arise with UPVC door mechanisms. These can include broken keys, snapped locks, faulty mechanisms, door misalignment, and so many others. D&M Locksmith aims to cater to each and every one of these issues and assures you that your UPVC doors and windows will be soon back in working order.

D&M Locksmiths is committed to providing quality service for UPVC doors by recommending the use of only the best locks. In many cases, euro cylinders are seen in residential properties and may be long worn out or poorly fitted to the doors. This leaves the property vulnerable to break-ins using specific techniques, or may someday suddenly snap in half. To avoid this, it’s important to regularly replace locks and upgrade them to more modern versions that usually have better security features and durability. 

A good example of viable lock upgrades is the BS3621 euro cylinder lock. Although generally more expensive than the generic ones, locks with the BS3621 designation are recognized by the British Standards Institute (BSI) as compliant with standard home insurance policy and thief-resistant.

Another type of upgrade from the generic euro cylinder locks is the 3-star cylinder lock. These cylinder locks are also designated as BS3621 locks and provide top-quality durability and security to deter criminals who attempt to illegally enter your home. Upgrading to 3-star cylinder locks usually go for around £105 to £140.

The costs of repairing UPVC doors can vary depending on which components need to be replaced or repaired. For UPVC Repairs, prices start at £130 for repairs while non-BS Standard euro cylinder fittings are priced around £75.
