Deadbolt Installation in Franklin Square, NY

A straightforward deadbolt swap on a door that already has a clean bore is the cheapest job. Cost climbs when the jamb needs reinforcing, when the door is out of square (common in older post-war framing that's settled over the decades), or when you want upgraded hardware like a high-security cylinder instead of a standard grade deadbolt.

The technician inspects the door and gives you the exact number by phone, based on what's actually there, before scheduling the visit. That range is $125 to $325 or more.

Call the dispatcher, give your address and the job, and the nearest available technician calls you back within a few minutes to talk through what you need and quote the price. Franklin Square's commercial strip sits where Hempstead Turnpike meets Franklin Avenue, but most calls here are to homes off Nassau Boulevard or New Hyde Park Road, and technicians working this hamlet know the residential side streets, not just the main roads.

Expect the technician on site in 15 to 30 minutes once the job is confirmed.

Know which door needs the deadbolt and whether you're replacing an existing one or adding a new bore. If you have a preference on finish or brand, mention it on the callback so the technician brings the right stock.

Clear the area around the door, inside and out, so there's room to work, and have someone available to let the technician in if the home has a locked storm door or gate blocking direct access.
