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.
