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.

- Ria GSeptember 30, 2026The chap was very professional with the installation and very patient with the team in explaining everything. Will only be using Optimus in the future
Nicole BurtonSeptember 25, 2026Gavin was amazing! Arrived quickly and was so lovely, fixed our door so now works perfectly again. Would highly recommend!
Iuliana CodruSeptember 17, 2026Excellent service from start to finish! He spent almost two hours patiently working on our door until he finally managed to get it open and replace the locking mechanism. He was very professional, friendly and didn’t give up until the job was done. Really impressed with the service and would definitely recommend him. Thank you!
- Danielle HegartySeptember 17, 2026Fantastic service from start to finish. He came out at very short notice and was incredibly knowledgeable, professional and helpful. I originally thought I would need to replace the whole mechanism, but he quickly identified a much simpler solution and saved me money, time and a lot of stress. The price was very reasonable too, and I really appreciated his honest advice rather than trying to sell me something I didn’t need. I would definitely recommend him to anyone needing a reliable locksmith. Excellent service!
AmySeptember 17, 2026Amazing service! Fast response, very friendly and helpful and really helped me out of a bind. Highly recommend!
Ann LSeptember 16, 2026I wish I could give Gavin more than 5 stars. My 86 year old mother wanted the lock on her front door checked as she was struggling with it. Gavin immediately diagnosed the problem and showed her how to deal with the issue rather than replacing the rather expensive lock, which would have cost £300. He then refused to take any payment! He also gave us some security advice which we appreciated very much. Without a doubt, if you are looking for a locksmith, I highly recommend Gavin
