About Us

Elevate Your Exterior With Transparent Service

"Leave it better than we found it."

See Thru Cleaning Services is a locally owned and operated exterior cleaning business based in Courtice, Ontario, proudly serving homeowners across Durham Region and beyond. Founded on a simple belief that exceptional service at a fair price shouldn't be hard to find, we've built our reputation one spotless window at a time.

We focus on the little details that separate a good clean from a great one: covering our shoes when entering your home, wiping down window sills, carefully placing ladders and taking pride in every job regardless of size. Whether we're cleaning a single set of windows or a full exterior package, you get the same attention to detail every time.

We're happy to take on larger projects outside of our home area. If you've got a job that needs doing, give us a call and we'll make it work.

Questions

Frequently Asked Questions

Everything you need to know before booking your clean.

How much does window cleaning cost?
Every home is different, so we provide free, personalized quotes. Pricing is based on the number of windows, storeys, and any additional services. We aim to deliver fair pricing. Contact us and we'll have a quote to you within 24 hours.
Do you clean inside and outside windows?
Yes! We clean both interior and exterior glass. When working inside, we cover our shoes and take care to protect your floors and furniture. We also clean frames and wipe down window sills as part of every job.
How often should gutters be cleaned?
We recommend at least twice a year — once in late spring after the pollen season, and once in the fall after the leaves drop. If you have large trees nearby, more frequent cleaning may be needed to prevent blockages.
How long does a typical job take?
It varies by home size and services booked. A standard window clean for an average home takes 1.5–3 hours. A full exterior package including gutters and soffits may take 3–5 hours. We'll give you a time estimate when we quote.
Do you serve areas outside Durham Region?
We're based in Courtice and primarily serve Durham Region, but we're open to larger jobs further afield, including Peterborough, Northumberland, and surrounding areas. Give us a call and we'll let you know if we can accommodate you.
What happens if it rains after my clean?
Rain water is actually much cleaner than it looks — it's typically the dust and grime that sticks to glass that makes windows look dirty, not rain itself. Your windows will still look great after rain. We also try to schedule jobs around the weather when possible.
