DOOR OR WINDOW HARDWARE?

What’s going
wrong?

Choose the closest fault and add your postcode. Review the message in WhatsApp, then attach a photo if safe.

Urgent or unsecured? Call Mark

Availability and arrival time confirmed by phone.

Mark will need to assess the door or window to confirm the repair. If your property is unsecured, call.

You review and send the message in WhatsApp. Add your photo there; this site does not upload it.

The lock, the mechanism or the alignment?

These are different parts of the repair. A key problem may involve the cylinder; a handle problem may involve the hardware or mechanism; a door that catches on the frame may need alignment work. An assessment establishes the cause.

Don’t force a stiff handle or key. Tell me whether the door is open, locked shut or unable to lock. If safely accessible, send a photo of the handle and the metal strip along the door edge.

A fault doesn’t automatically mean you need a whole new door. I’ll explain the options and quote for the required work.

Full mechanism prices depend on the make and model, access and work required. Mark will identify the mechanism and agree the total parts-and-labour price before work starts. A gearbox-only replacement is a different repair.

Ask for the total for your job, including labour and any replacement parts. Tell Mark your postcode, door type and preferred appointment time. Specialist hardware and evening or weekend work are quoted before booking. No VAT is added; agree the full price before work starts.

Patio-door lock repair · NE34

In a verified Checkatrade review titled “Lock on patio door”, posted 1 August, the customer describes an arranged visit and completed work. Mark then asked the customer to check the result thoroughly.

The review does not specify the replacement part. For your uPVC or composite door, the fault must be assessed before deciding between cylinder, gearbox, full mechanism or alignment work.
