How does the age of a St. Catharines home change the clean?
The oldest cottages in Port Dalhousie date from the 1820s, when the first Welland Canal was dug. Mill owners built large houses on Yates Street in the late 1800s and early 1900s, and suburbs spread after the war. Tell us your neighbourhood when you ask for a quote and the number starts closer to right.
| Built | Where you find them | What it means for the clean |
|---|---|---|
| 1820s to 1930s | Port Dalhousie, between Lake Ontario, Martindale Pond and the harbour | Frame cottages beside houses from every decade up to 1930s Tudor revival. Older floors and trim take hand work. Tell us about any surface you want left alone. |
| Late 1800s and early 1900s | Yates Street, along Twelve Mile Creek | Large Georgian and Tudor houses built for mill owners and managers. More rooms, more trim and more stairs, so quote by room count, not floor area. |
| A separate town until 1961 | Merritton | Older streets that grew up before the merger. Stairs and a basement laundry add time, and a finished basement counts as another floor. |
| After the war | Suburban streets built as the city spread out | Bathroom count and a finished basement set the time more than the age does. Tell us both. |
| Student rentals | Streets near Brock University | Turnover between leases. A move-out clean covers the inside of every cabinet, closet and drawer, plus the oven and fridge. |

Do you clean heritage homes in Port Dalhousie and on Yates Street?
Yes. Port Dalhousie was a canal village from 1826 and the northern end of the first three Welland Canals, and the heritage district still takes in their entry locks from 1826, 1848 and 1885. The village and harbour now fall under two of the city's five heritage conservation districts.
Yates Street grew up along Twelve Mile Creek in the late 1800s and early 1900s. The mill owners and managers who lived there built big houses in Georgian and Tudor styles that are rare in the rest of the city.
Plaster walls, older floors and painted trim need more hand work and less water. If a floor has been refinished, or a surface should stay untouched, tell us when you book. A first deep clean from $249 covers baseboards, door frames and grout, and recurring visits from $129 keep it there.
Do you cover Merritton, Port Dalhousie and Grantham?
Yes. All three were separate until 1961, when the Town of Merritton, the Village of Port Dalhousie and Grantham Township joined St. Catharines, according to the City's history. Plenty of people still give their address by the old name. Same city, same flat prices.
The city grew from 133,113 people in 2016 to 136,803 in 2021.
Can you clean a rental near Brock between tenants?
Yes. Brock University is in St. Catharines. If you rent a house or apartment to students, plan the clean between leases, before the keys change hands.
A move-out clean from $279 covers the inside of every cabinet, closet and drawer, the oven, fridge and range hood, and the windowsills and tracks. Book it for the day after one tenant leaves and the unit is ready when the next one arrives.
Where does St. Catharines tap water come from?
Lake Erie. It comes in through an intake on the Welland Canal near Allanburg and is treated at the DeCew Falls Water Treatment Plant, which Niagara Region runs, according to the City of St. Catharines.
Lake or well, white spots still build up on shower glass and taps between cleans. Every residential clean polishes mirrors and fixtures, and a deep clean scrubs grout and tile.
Do you clean the rest of Niagara and Hamilton?
Yes. We have crews in Niagara Falls, Hamilton, Burlington and Brantford. Our office is in Guelph. Offices, clinics and shops in St. Catharines can ask for a commercial cleaning quote. The full list of service areas covers all 20 cities.
