"Nathan showed up on time on the same Saturday that I called, for rekeying the security door bolt lock, since we had lost one set of keys. He advised me to rekey the deadbolt on the inner, stouter door, and charged only slightly more. Excellent service!"

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Great work from Daniel and his team. Innovation Painting took care of our home in San Francisco. Prompt, friendly, and great attention to detail. After they were done painting, Daniel walked me around the property to go over things they uncovered while painting, like suggested repairs, which I very much appreciated. I would absolutely recommend Innovation Painting. Thanks!"

"Darrin fixed an increasingly problematic front door mortise lock. Works swell now; it was a toughie. He also fixed two other outside door locks that had been iffy. Prior repairman who had installed the locks and doors didn't do a great job. Now we have working and locking doors. Spiffy. I thought the price was very reasonable. He was professional and knowledgeable. Will hire him again for any lock issues. I wish I had done this over a year ago instead of dreading it (afraid we would have to replace the locks or doors)."
