Detroit Lock and Door was called since several locks around the house became hard to work with as they got old. Ben was very flexible in regards to the timing of the visit, although the weather conditions that day were pretty bad. It is a pity that they cannot fix something like this, however, Ben successfully dealt with the issue and also lubricated some locks, which are now working much better. Ben was polite and did not hurry during the work. The price is also very reasonable. I strongly recommend Detroit Lock and Door.
