Do you work with contractors and builders in Markham?

Yes — most of our Markham post-construction work is for builders, renovators, and developers on rough, final, and sparkle schedules.

Can you handle fine drywall dust?

That is the core of the job. We use HEPA-filtered extraction and multi-pass dusting so fine construction dust is actually removed, not spread around.

How quickly can you turn a site around?

Crews scale to the deadline. A typical Markham new-build home final cleans in one day; commercial spaces are scheduled phase by phase.

Are your Markham cleaners insured and background-checked?

Yes. Every Tbay Cleaning Services crew member working in Markham, ON is fully insured, bonded, and background-checked before entering any home or workplace.

Do I need to provide cleaning supplies or equipment?

No — our Markham crews arrive with professional-grade equipment and eco-conscious products. If you prefer we use your own products, just mention it when booking.
