Top service, even on Sunday!
Called on Sunday afternoon with ontstoppen.nlbecause my kitchen drain was clogged. The plumber arrived at 09:00 the next day. He cleared the blockage quickly and, as agreed upon over the phone, for a fixed price.
Great experience with this company and definitely recommended! Especially in this industry where scams are so common...
