Handyman services in Newmarket

These are the repairs Newmarket homeowners ask us for most often, from drafty doors to old outlets and leaking taps.

Renovations and repairs across Newmarket

We work across Newmarket, in Historic Downtown and Old Main Street, Lower Main Street South, Yonge-Davis, Glenway and the streets around the hospital.

Near the old core some houses are more than a hundred years old, and a renovation there usually reaches the wiring and plumbing. Most other homes in town went up between the 80s and 2000, and they are ready for new kitchens, bathrooms and finished basements.

Small jobs are welcome too. Book a handyman online, or call us for a visit and a written quote.

  • CNG Contracting! Claudio did an amazing job with our condo reno! He worked with us to ensure we were satisfied with every single detail. Giving us choices based on our budget. He was honest (with what needs to be done and not), patient, reliable and made our vision a reality!
    His use of tech was also very impressive and helpful with 3D designs, online process for cost tracking, progress pictures and payment approval etc. He has changed our expectations from contractors!

  • From day one. The clear explanation and detailed estimate made us understand what we needed to know in terms of time lines and cost.

    Claudio and CNG team completed a very difficult task to demo all three bathrooms on our upper and main floor as well as , kitchen floor foyer and complete the project within the expected timeline and before Christmas. All in all 5 weeks.

    Incredible communication and cleanliness. Safety for DNA high priority for this guys. Our home had a site final clean up for us not to worry about anything.

    We definitely would use their services again and will recommend CNG contracting to family and friends.
