"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"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."

"I can’t say enough great things about Walter! He completed multiple projects in my home, and every single one was done with precision, professionalism, and attention to detail. From start to finish, he was reliable, communicative, and clearly takes pride in his work. He showed up on time, came prepared, and handled everything efficiently—no shortcuts, just quality craftsmanship. What really stood out to me was how he took the time to explain things, offered helpful suggestions, and made sure I was completely satisfied before wrapping up each project. It’s not easy finding someone you can trust in your home, but he exceeded all expectations. If you’re looking for someone dependable, skilled, and professional, I highly recommend him. I will definitely be using his services again!"

"Barry from Mr. Handyman was fabulous! We purchased four hours and he did twice the work we expected to accomplish with that time! All the work accomplished was very high quality. Will definitely be back to Mr. Handyman the next time we need service, and will be asking for Barry!"
