Once again, it was Ace to the rescue! I had a final walk-through yesterday morning in Medfield, and the evening prior, the cleaners locked the door from the house to the garage. I had the garage code and the garage door opener. The buyers had an early closing and the moving trucks had arrived. One call, and John arrived in less than 10 minutes! What started out as a stressful morning for the buyers turned into a nice experience, the closing was not delayed, and the movers were able to start unloading immediately.

Thank you Pete for always taking the call, and John for coming so quickly! You were wonderful and saved the day! We Realtors in the area should all have you on speed dial! I wouldn't call anyone else. Ace has come to the rescue numerous times in my 20+ years selling real estate - they are reliable, speedy and quite reasonable! The best!

In and out in less than 10 minutes. He copied my flip car key and even let me test it to ensure it worked before I left. Great work, very knowledgeable and nice. Not much more you can ask for.

Pete came over and took a look at my lock and told me it was working fine and that there might have been something stuck in it when I got locked out. I appreciate his honesty and that he didn't try to give me the hard sell for a new lock.

Locked myself out of my apartment. . Called Ace and within 5 minutes a locksmith called and about 5-10 mins later showed up. Opened the door in about 20 seconds (so much for a security door lock). Locksmith was really friendly and skilled. Made what could have been a really bad and stressful day and turned it into a funny story.
