Residential Cleaning
Whether you're looking for dependable routine maintenance or a more thorough refresh, CST ProNet offers cleaning solutions designed around your home, lifestyle, and expectations.
Careful work. A dependable team.
A coordinated team and consistent attention to detail, with a clear scope before every visit.
Thorough from the first tier
Our Basic Clean is intentionally more complete than a quick surface clean. We focus on the details that make a home genuinely feel cared for.
Typical team times
A modest-sized home often takes about 2 hours; a larger home is commonly around 2½ hours. Deep cleans generally land around 4–5 hours, depending on the home and its condition.
Your quote is your ceiling
Once we confirm a quote, we do not charge more than that quoted price for the agreed scope of work. You know the maximum cost before the work begins.
100% satisfaction matters to us.
If something does not feel right after a cleaning, tell us. We are happy to work with you to make it right — whether that means returning during the week for a touch-up or, when appropriate, moving the following cleaning up one service tier.
A cleaner home. A more comfortable living space. Professional care tailored to your needs.

The story behind the clean
Built together. Grown through care.
CST ProNet was born in Montreal in 2020, when Christian and his sister Sarah found themselves facing a period of enormous uncertainty. Drawing on their roots in restaurants and hospitality, they came together and put everything they had into building something that could carry them through those difficult times — working hard, learning quickly and committing themselves completely to making it work.
But from the beginning, it was about more than getting through it themselves. Christian and Sarah wanted to make life a little easier for other people too, taking one worry off their shoulders by creating cleaner, more comfortable homes and workplaces. As CST ProNet grew, Christian’s wife Anne-Marie joined the team, bringing her own energy and care to helping get the job done. That family spirit still guides the company today: work hard, treat people well and leave every space — and every client — a little better than we found them.
Human touchYou are never just a job number.IntegrityClear expectations, clear pricing and honest communication.CareWe clean with attention to the people who live and work there.
Caring beyond the clean
A cleaner home. A stronger community.
From time to time, CST ProNet organizes donation drives for clean, gently used clothing and unopened non-perishable goods. It is a simple extension of the way we work: if we can make life a little easier in someone's home, we can carry some of that care into the community too.
