Common uPVC window lock problems

Window locks and handles on older sash and casement frames in Harrow on the Hill and Pinner tend to stiffen and snap with age, and uPVC window locks fail too. We repair or replace them so your frames close and secure properly.

A handle that turns but does not lock, a handle that has snapped, or a window that will not close tight. Most of these come from a worn handle or a failed espagnolette, the locking bar inside the frame.

We replace handles with locking handles where you want them, so windows can be locked with a key, and fix or replace the mechanism behind them. Patio and French door locks are part of the same job.

Window lock repair in Harrow: common questions

How much is a window lock repair in Harrow?

From £69 for a uPVC window handle or lock. If the locking mechanism inside the frame has failed, the engineer tells you the price for that before doing it.

Can you fit locking window handles?

Yes. We fit keyed locking handles to uPVC windows, often asked for by insurers and by parents of young children.

Which areas around Harrow do you cover?

Every HA postcode on the mainland, plus nearby towns such as Wembley, Pinner, Northwood, Stanmore, Edgware, Kenton. If you are not sure, call and we will tell you straight away which engineer can reach you.

How quickly can someone get to me?

An engineer is typically with you in 15 to 20 minutes, and within 30 minutes at most. We give you a time on the phone based on where the nearest engineer is right now.

My window will not close properly. Can you fix it?

Usually, yes. It is often the hinges or the keeps that need adjusting, which is quicker and cheaper than replacing parts.

How do I pay?

When the job is finished. Card, cash or bank transfer, and you get a written receipt you can use for an insurance claim.

I live in a flat near Wembley Stadium. Can you reach me on an event day?

Yes, we cover Wembley around the clock. Roads near the stadium can be slow on event days, so give us your address when you call and we will confirm the arrival time.

Can you change the locks on a 1930s semi without replacing the whole door?

In most cases, yes. The engineer checks the door and fits a new cylinder or mortice lock to suit it, and confirms the price before starting. If the door itself is badly worn, the engineer will tell you.
