This week, Andrew Horton, who has been a window cleaner for more than two decades and knows the secrets of the trade and safety practices, will be responding to readers’ questions about his career.

Readers who would like to ask Mr. Horton a question should do so in the comments box below. His first set of responses will be published on Wednesday.

Mr. Horton, 54, has worked on landmark buildings all over the city, including the Empire State Building, the Twin Towers, the Hearst Building and dozens of others.

He said he was always content with his job until one day, hanging off the 86th floor of the Empire State Building with just a belt tying him to a window, he decided that he should rethink his livelihood.

Mr. Horton now runs New York City’s main safety training program for window washers at the building service workers union 32BJ, teaching future window washers how to reduce risks and promoting safety while working a thousand feet up in the sky.

“What’s more important up there?” he asks. “Prevention, prevention, prevention!”

Mr. Horton was born and raised in New York City. He is married, has two sons and lives in Queens. He enjoys fly fishing and is a youth basketball coach at his parish.
