Greensborough: Neighbourhood Notes
Greensborough lies around Markham Road and Major Mackenzie, a neighbourhood of 2000s and 2010s homes built on former farmland with trails and ponds woven through it.

Neighbourhood character
Greensborough was one of the larger northeast Markham developments of the 2000s, with detached homes, semis and townhouses lining crescents that wrap around parks and stormwater ponds. Newer phases continued into the 2010s. Most homes have full basements, and many owners have finished them since moving in.
Former farmland, heavy clay
The land here was farmed for generations before it was built on. The soil is dense and slow to drain, which keeps sump pits busy after every big rain. If your pump seems to cycle more each year, check that the discharge pipe outside is clear and not draining back toward the house. A frozen or crushed discharge line is one of the most common reasons a pump overworks.
Renovation reminders
When a basement is finished, the sump pit and the main cleanout must stay accessible. We often find them boxed into a closet with no removable panel. A simple access hatch now saves cutting drywall during an emergency later.
From the van: Mark the location of your cleanout and sump on a sketch of the basement and keep it with your house papers.
Local note. Many homes have finished basements, so a backwater valve and sump backup are worth a look.
