Homes and pipes in Milliken Mills
Most houses in Milliken Mills were built in the 1970s and 1980s, filling with detached houses, semis and town rows along streets around Milliken Mills Community Centre and Pacific Mall. Many still have original copper supply lines, cast iron or ABS drains and clay sewer laterals. Homes built or renovated in the 1980s are the most likely in Markham to contain Poly-B supply pipe.
Many households here are multigenerational, which puts more demand on bathrooms, kitchens and water heaters than the original builders expected.
Calls this corner of town makes
- Poly-B supply lines that insurers want replaced.
- Main sewer backups from roots or settled laterals.
- Water heaters struggling to keep up with larger households.
- Kitchen drains clogged from busy cooking.
Poly-B is the big one here. If you see grey plastic pipe in the basement ceiling, our Poly-B replacement page explains how we approach it. For recurring backups, main sewer line clearing and a camera inspection are the usual first steps.
Through the seasons here
Heavy rainstorms in summer can overwhelm older sewers, and homes without backwater valves are at risk of basement flooding. In winter, pipes near outside walls in older homes can freeze, especially in basements with thin insulation.
Planning ahead in an older home
Homes here are at an age where several major systems may need attention over the next few years: supply pipes, water heaters, sewer laterals and shut-off valves. Tackling them in a planned order is far less stressful than reacting to emergencies one by one. We can walk through your house, show you what we see and help you set priorities based on condition and budget.
Families who cook often should also be careful with grease. Pouring fat down the kitchen sink is the most common cause of clogs we clear here. Let it cool in a tin can, then into the green bin it goes instead. Our what not to flush brief covers bathrooms as well, which matters in busy multigenerational homes.
