Why Markham Homeowners Choose ProFlow for Sump Pump Installation & Repair

Every community has unique plumbing characteristics shaped by housing age, soil conditions, and local infrastructure. Our technicians are experienced with the specific challenges that local homeowners face — from the properties in Unionville to the homes in Cathedraltown.

Aging Cast Iron Drain Stacks

Heritage homes in Unionville and Markham Village often have 80–120 year old cast iron drain pipes. Internal rust buildup narrows the pipe diameter, causing chronic slow drains and sewage odours. Our camera inspection reveals the pipe's condition, and trenchless relining can extend its life by 50+ years without tearing into walls.

Local Tip

Unionville's protected heritage district contains some of Markham's oldest homes, many dating to the mid-1800s. These properties often have original cast iron drain stacks that have corroded from the inside out over 100+ years. If you hear gurgling drains or notice slow drainage throughout the house, the cast iron stack may need lining or replacement. We use trenchless pipe lining technology to restore heritage home plumbing without damaging walls or floors.

Every ProFlow technician is licensed through the Technical Standards and Safety Authority and carries full insurance coverage. All work meets or exceeds Ontario Building Code requirements.

Frequently Asked Questions

How do I know if I need a sump pump?
If you notice dampness, musty odours, or visible water in your basement — especially after rain or during spring thaw — a sump pump is likely needed. Homes in low-lying areas, near Lake Ontario, or built on clay soils are at higher risk. We offer free assessments to evaluate your property's water table level.
Do I need a battery backup for my sump pump?
We strongly recommend it. Power outages often coincide with heavy storms — exactly when you need your pump most. A battery backup keeps your system running for 8 to 12 hours without power. For homes with finished basements or valuable belongings stored below grade, it's essential insurance.

Sump Pump Installation & Repair in Markham typically ranges from $800 – $3,000 (CAD). Basic sump pump replacement from $800. New pit excavation and pump from $1,500. Battery backup add-on from $600.
