The best emergency services! Fire, smoke, water, you name it. KBS can handle it. There is a person by the name of Billy that will keep the customer calm, and make sure the job is done right. Not sure what I would have done without Billy and his team of professionals. Big or small, give KBS a call!

We've been using KBS Maintenance since 2010 and this review is long overdue. They have been bringing our floors back to life year after year and have gone beyond the call of duty (working weekends or nights without overcharging us) to make sure they happen on time. Used them once for a cleanup when a water main broke and like always handled it perfectly. Keep up the good work and thanks.

The best service in Montreal!!! I've tried several other companies, but with KBS Maintenance inc. I was very satisfied. They are punctual, very detailed and over all organized. I highly recommend them.
