Lock and door
services in Windsor.
You don’t need to know the name of the lock. Tell us what you need from the entrance: urgent access, a repair, new keys or an agreed upgrade. We’ll discuss the fitting as well as the product.
Mortice and rim locks
A new lock needs to work with the door and its existing preparation. We assess mortice and rim fittings, explain compatible options and discuss whether a replacement or fresh installation is needed. Photos of both sides of the door help with the enquiry.
Lost or unreturned keys
If you cannot account for all the keys, we can discuss changing the relevant cylinder or lock. List the entrances you want covered and how many people need new keys, so the agreed work matches the way you use the property.
Lockouts at home
Keys inside or a lock that has stopped working? Call and tell us whether the door was pulled shut or locked with a key. We assess the entry options and explain any repair or replacement needed before proceeding.
Faulty door hardware
A loose handle, catching latch or stiff key may have more than one cause. We check how the fittings operate and how the door meets the frame before recommending an adjustment, repair or replacement.
Commercial security work
For a business entrance, we can discuss replacement locks, master key arrangements and access control. Start with who needs access, which doors are involved and who can approve the work, then we can agree a suitable scope and specification.
See all our residential services and commercial services. For a faulty uPVC mechanism, read about multipoint door lock repairs and replacement.
Choosing new hardware
Start with the door.
Then choose the lock.
A familiar brand name is only part of the decision. The existing door, lock furniture and any written specification determine which options are suitable. Send those details when you enquire so we can discuss the actual fitting work.
If the finish or appearance matters, photograph both sides of the entrance and tell us what you would like to retain. We’ll explain compatible choices and any changes the work may require before you approve a replacement.
