How We Can Help
• Handles supplied & fitted: key-locking espagnolette handles (inline/offset), tilt & turn handles, cockspur, and sash fasteners for timber. Finishes to match your décor (white, black, chrome, brass).
• Internal mechanisms replaced: espagnolette strips, multi-point shootbolts, tilt-and-turn gearboxes, keeps/strikers, cams and drive gears.
• Hinges & stays: friction stays, Egress/easy-clean hinges, butt/flag hinges and sash balances for uPVC, aluminium and timber—cures sagging, draughts and poor sealing.
• Safety & access control: child-safety restrictors, ventilation (night-vent) settings, keyed handles for insurance compliance and better key control.
• Repairs without replacing frames: failed gearboxes, seized handles, broken spindles, mis-aligned keeps, stiff or jammed sashes, windows that won’t open/close or won’t lock.
• Weatherproofing & alignment: re-toe & heel of sashes, gasket/trim replacement and hinge adjustment for a tight, rattle-free seal.
• Patio & roof windows: additional locks for sliding windows, secondary locks for rooflights and anti-lift devices where suitable.
Common signs you need us
• Handle turns but the window doesn’t lock/unlock.
• Key spins, or won’t come out.
• Window catches on the frame, feels loose, or is draughty/noisy.
• Tilt-and-turn stuck in tilt or won’t engage the turn position.
What you get
• On-site diagnosis and clear pricing.
• Quality, insurance-rated hardware where required, fitted neatly.
• Non-destructive methods wherever possible, and a parts & labour warranty.
From a single stiff handle to a full house of replacements, we’ll restore security, ease of use and proper weather sealing across your windows.

He was a good price, cheaper than others I called!
I would also like to add that as a woman on my own, I felt comfortable with him doing work in the house.
Will defo use again if needed!

Guests locked out
Called Gav out after one of my Airbnb guests locked themselves out. After waiting 3 hours for the previous locksmith, Gavin arrived within half an hour and had my guest back inside within minutes. Fast, reliable, and professional service — highly recommended.

Excellent service from Gary
Excellent service from Gary! We were a bit stuck tonight as our door was not locking. He saw our Facebook post on a community page and within 30mins was here and sorted. My mum is very vulnerable with a condition and this did worry her before sorted! Super friendly and very knowledgeable! Thank you for everything.

Highly recommend.
I sent Gavin some photos of a faulty back door lock/handle and he provided a very reasonable quote. As he was already in my area he arrived within a couple of hours and stuck to his quote even though the job took longer and there was slightly more involved. Gavin is very genuine, friendly and personable and explains everything in detail. He made sure I understood all my options before starting the job.
