Lowell is a dry cleaning facility in Tenafly. It is bigger than your usual mom and pop stores, but it still good to use. They also store items for winter storage or things of that nature. If you have furs for example, they will store those for you. In addition, Lowell Cleaners does alterations and things of that sort. I have not had anything tailored there so I can't comment on that service, but just figured I'd mention that they have it.
Prices are competitive with the rest of the dry cleaning industry and this is another option to consider if you are in Tenafly.
