Safe & vault work across Nassau County, Long Island
Nassau County, on Long Island's western end, runs from the Gold Coast estates of the North Shore — Old Westbury, Sands Point, Brookville, Muttontown, Locust Valley — to the established family villages of Garden City, Rockville Centre and Syosset. The work is suburban and often substantial: larger home, fire, document and gun safes set into basements, mudrooms and closets, estate and inherited-safe openings in the grand North Shore houses, and home and jewelry safes in the well-off villages and along the Manhasset and Great Neck retail corridors.
Access is generally easy — driveways and garages let us bring a heavy safe right to the install point — though the larger North Shore estates can mean long, gated driveways we plan around, and a few waterfront homes call for flood-aware placement.
Nassau is outside the five boroughs, so we book it in: we come from our Manhattan base through the Midtown Tunnel and out the Long Island Expressway, the Northern State or the Grand Central, and always give you an honest ETA. Every job is licensed and insured, openings are non-destructive wherever possible, and you get a clear, upfront quote with travel accounted for.

“We were desperate to get our safe open after two companies tried and failed. Sherlock replied right away and was on site immediately with no notice on a Saturday. They got the job done fast and honestly. Thank you so much.”
Sabrina Dabakarov
Emergency Safe Opening · 2025
“I was looking to move a 500lb safe and had difficulty finding a mover. I called a few companies and got a run around. When I called Ari over at Sherlocks Safes he asked for some pictures of the safe and move. Within 24hrs he gave me a price and scheduled the move in a time frame that worked for me. The two men that showed up were great. They took great care in moving the safe through very narrow passages. There was no damage, they were quick and efficient at the job. If you're looking to move a safe then Sherlocks Safes is your best bet. I highly recommend them.”

“Prompt, professional, and comprehensive! We had an evening safe situation and Ari responded almost immediately. He gave us a quote (which he stuck by) and was able to arrive the next morning at 9am. Not only did he open the safe, he made it workable again. One of the most reasonable quotes and definitely the fastest service — it is hard to find those two together. Thank you, Ari!”
