Sean is a honest professional. I WhatsApp him to seek help because I cannot open my letterbox with my key. He responded promptly and attentively listens to my problem. Then he advised me to try spraying the lock with WD-40 before attempting to open the letterbox. It works! Sean did not charge me any fee. He could have come down then charge me a service fee by spraying WD-40. Next, he could have try to get me to change my lock. I really appreciate that he is genuinely in helping his clients. This incident shows that he does place his client first before business. Should I really need a locksmith, I will find you again. Wish you have a prosperous business.

Very professional and responsive. Provided me with a quote for installation at a reasonable rate. Text me before reaching my home. Fixed the new lock and even gave me some advice on maintenance of the locks. Thumbs up for the young guy that did my locks! Highly recommended!
