"The locksmith had to rework the new deadbolt I bought to make it fit the door and rekeyed the existing lower knob lock to make one key work on both locks. It was a longer job but the work was exceptional and amazingly cheap!"

"I was told arrival time would be 30-40 minutes. It was much longer (over 1 1/2 hours). But he did a fine job when got there. The real problem was the home advisor system. I had multiple companies contacting me and after I contracted with one, another called and lied, saying the locksmith in route did not work for company and saying he was coming instead. What a fiasco. I was at work and had just had a home break in. It was atrocious. I will not use home advisor again."

"Arrived 2 hours outside 3 hour window, but did at least call to say they'd be late. Low-tech vent cleaning: a drill, a wire brush, and extension cable, two guys in a car, a short ladder, a small vacuum cleaner. I've had an entire house's vents steam cleaned before at the price they charged for 20 feet of dryer duct. Too expensive for the job and amount of effort put in. The invoice said Locksmith so obviously they do this on the side. The job was passable, just not super thorough. Not recommended."
