uPVC Door Repairs in Cantley

Door Difficult to Lock, Stiff to Close or Jammed Shut?

A common problem with uPVC doors is that they gradually become difficult to lock. You may notice the handle becoming harder to lift, the key stiffening, or the door needing a push to close properly.

These problems are often caused by poor alignment, worn locking components or a failing multipoint mechanism.

We regularly repair:

• Failed uPVC door gearboxes
• Doors stuck in the locked position
• Broken multipoint locking mechanisms
• Stiff handles and difficult-to-turn keys
• Dropped and misaligned doors
• Faulty door cylinders and damaged handles

Where possible, we repair the existing door rather than recommend replacing it.

Correct door alignment is just as important as fitting a replacement lock. If a door is putting unnecessary pressure on the mechanism, even a new gearbox can fail prematurely.

Composite Door Lock Repairs in Cantley

Patio and French Door Repairs in Cantley

Patio doors and French doors can become difficult to operate as their locking mechanisms, rollers or hinges wear.

Sometimes the door is still in good condition, but a relatively small locking component has failed.

We repair sliding patio doors, French doors and more complex tilt-and-slide locking systems.

Common faults include jammed handles, dropped doors, damaged gearboxes, and doors that no longer lock securely.

Before spending money on replacement doors, it’s worth finding out whether we can repair the existing ones.

Window Lock and Handle Repairs

We don’t just repair doors. We also repair window locking mechanisms throughout Cantley and Doncaster.

A window that will not open, close or lock correctly could have a broken gearbox, worn hinges or a faulty handle.

We repair uPVC window mechanisms, replace damaged handles, and service tilt-and-turn windows.

We can sometimes repair even older windows with hard-to-source parts, avoiding the expense of replacing the whole window.

Frequently Asked Questions

Can you repair a uPVC door that won’t lock?

Yes. We repair faulty multipoint mechanisms, broken gearboxes and misaligned doors. In many cases, we can repair the existing door without replacing it.

Should I change the locks when moving into a new house?

We recommend it. You cannot be certain how many copies of the original keys exist. Replacing the locks means the previous keys will no longer operate them.

Do you fit anti-snap locks in Cantley?

Yes. We supply and fit Ultion high-security cylinders and other anti-snap lock options for suitable uPVC and composite doors.

Can you realign a door that is difficult to close?

Yes. We can adjust many uPVC and composite doors to improve their operation and reduce strain on the locking mechanism.

Do you charge a locksmith call-out fee?

No. SF Locksmiths doesn’t charge a call-out fee, and a two-year parts and labour guarantee covers our work.
