“Brilliant service. I was locked out in Kettering late on a Sunday—he arrived quickly, opened the uPVC door without any damage and fitted an anti-snap cylinder there and then. Clear pricing, card machine on hand, and everything worked perfectly before he left. Highly recommend.”

“Had deadlocks and hook locks fitted to my Transit in Corby. The install was neat, doors close better than before, and I got the paperwork for my insurer. Professional from start to finish and great advice on keying the locks alike—top job.”
