TESTIMONIALS

What Clients Say About Us

DJ was punctual, courteous and so efficient throughout the whole service process, which saw us change out all my smoke detectors, and a few light bulbs in hard to reach areas of my home.

I am looking forward to booking my next service with DMZ Maintenance & Contracting Services, as they are honest, communicative and made me feel comfortable that the work would get done properly and with care. Highly recommend giving them a try - Just amazing!

Home Owner/Bank Retiree

From the moment I spoke to DJ, Owner, at DMZ Maintenance & Contracting Services, I knew that I was in good hands. He took the time to listen to what I needed, as I was looking to put my condo up for sale and he created a plan and estimate for me right away. The services included changing out 4 pot lights, caulking and helping me pack up my smaller belongings and moving those to a facility storage just down the street. The job we done on time and it went so smoothly! I highly recommend!

J.G. in Markham, ON

Condo Owner/Mgr. of Operations

DMZ Maintenance & Contracting Services was recommended to us by a friend. I cannot tell you how happy we were when DJ, the Owner, came to see our ceiling fan that needed replacing. He was on time and so friendly during the whole process, and, even cleaned the parts that were being reused. We also had some caulking re-done in the kitchen area and he left our place so clean after he finished with the tasks. Our friend was right - this maintenance service provider was exceptional. We loved that they are local as well!
