Deadbolt Installation: reading the quote

Residential deadbolts are graded under an industry standard in three categories, security, durability and finish, with letter grades from C through A, so a lock marked with three A grades has met the highest level in each. Heavier commercial-pattern bolts are graded 1, 2 or 3, with 1 the highest. The grades let you match hardware to a busy family door or an exposed side entrance without relying on the weight of the box.

Hardware supplied by you or by the locksmith

If you have already bought the lock, the quote covers labour and any adaptation of the door to that kit. Hardware supplied from the van is listed separately with its grade and finish.

New bore or replacement into existing holes

Boring a door that has never had a deadbolt takes more time and tooling than dropping a new bolt into holes that are already there, and the quote reflects which of the two your door needs.

Removing and disposing of the old hardware

Some visits end with the old deadbolt and strike left with the homeowner, and others ask for it to be removed and hauled away. Taking the old hardware away adds a small amount of time and is agreed before the new deadbolt goes in.
