From first visit to final walkthrough

  1. 1

    Site visit & scope

    We walk the space with you, measure, and understand what the finished result should feel like.

    Written estimate

    A clear, itemized quote — materials, labour, timeline. No moving numbers once we shake hands.

  3. 3

    Build & updates

    Floors and furniture protected, daily clean-up, and you're kept in the loop the whole way.

  4. 4

    Walkthrough & warranty

    We finish the punch list together, hand back a spotless space, and stand behind the work.

“He did an outstanding job from start to finish… installed new waterfall style quartz countertops that look absolutely stunning. On top of that, he fixed a pre-existing water leakage problem that he discovered. He took great care to protect our floor and furniture, and left our home looking spotless.”

J. Fang · Kitchen renovation

“Roger did an amazing job in our new photography studio. He made a large cyclorama, a wainscotting wall, did plumbing for our washroom, installed decorative wood slats and a utility sink… delivered outstanding work that was better than our dreams.”

Who you're hiring

A contractor who shows up, and finishes

RMGC Construction Inc is a North York–based construction company led by Roger, working across Toronto and the surrounding GTA. We take on residential renovations and commercial build-outs — and the responsibility that comes with them.

That means arriving when we say we will, protecting your floors and furniture before the first tool comes out, flagging problems we find behind the walls instead of covering them up, and leaving the space cleaner than we found it. Most of our work comes from referrals and repeat clients — the only endorsement in this trade that really counts.

We carry $5,000,000 in liability insurance and are WSIB insured — your property and everyone on your site is properly covered, on every job, without exception.

  • $5,000,000 liability insurance
  • WSIB insured & in good standing
  • Written estimates & workmanship warranty
  • Licensed trades — plumbing, electrical & HVAC
