The team came out to look at a register we wanted moved to see if it could be done. They ended up being able to move it to a new location that same day. Very pleased with the communication and service!
I recently hired Mailloux Mechanical, and I couldn’t be more impressed with the entire experience. From the moment I called to schedule an appointment, their customer service was friendly, professional, and responsive. They were able to fit me in quickly, and did a fantastic job at a great price.
