I called on a Monday late afternoon to see if they could change a door lock/key. They had several clients on the list but still made it out promptly that very same evening-- and called to give me notice before arriving.
Totally professional, they got to work right away and also made recommendations of other ways to increase security around the house (nothing they were charging for or would benefit them in any way). They were efficient and quick, and very friendly. Costs were more than reasonable, and they didn't charge for a couple of extra things they ended up having to do to get the job done.
I would DEFINITELY call them again or recommend them to friends for any future needs!
