At Windowcare Northwest, our dedicated repair service – known as the Window Doctor – specialises in repairing faulty, damaged and worn windows and doors in Southport, Merseyside, Lancashire and across the North West.
Whether you have misted glass, broken locks or draughty frames, we can restore your windows and doors quickly and cost-effectively.


If your double glazing has become misted or cloudy, the sealed unit has likely failed. This does not mean you need a full new window. We replace:
Misted double glazed units
Cracked glass panels
Smashed window glass
Failed sealed units
Patio and door glass panels
New energy-efficient units are fitted into your existing frames, restoring clarity, insulation and appearance without the cost of full replacement.

Multi-point locking systems
Window locks
Door locking mechanisms
Security lock upgrades
All repairs are carried out using high-quality, secure components for peace of mind.
Worn or damaged hinges can cause windows and doors to:
Drop or catch when closing

We repair and replace faulty hinges to ensure smooth operation and a proper seal.
If your sliding patio doors feel heavy, stick or won’t glide smoothly, worn rollers are often the cause.
