Is your Oakville home’s weeping tile still connected to the sewer? In many older homes, it is. During heavy rain, that connection sends groundwater into the wastewater system, which can back up into basements across the neighbourhood.

We offer weeping tile disconnection, sump pump installation, sewer repair and downspout disconnection across Oakville, from Old Oakville and Bronte to Glen Abbey and Joshua Creek.

Halton subsidies of up to 100%

Halton Region pays up to 100% of eligible costs to disconnect weeping tiles, exterior storm drains and downspouts from the sewer. For backwater valves and sewer lateral repair, it pays 50% up to set limits. You must apply within one year of completing the work.

Proof and paperwork done right

The Region needs proof of the existing stormwater connection, a building permit where required and before and after evidence. We provide a licensed plumber’s assessment, record photos and CCTV footage and give you an itemized invoice that lists materials, labour, CCTV and permit costs.

Sewer repair under mature trees

Older Oakville streets have beautiful trees and older sewer laterals. We camera the line and use trenchless methods where they fit, so your landscaping stays in place.

Oakville homes

What Oakville homeowners call us for

Housing in Oakville

Oakville has older lakeside neighbourhoods with large lots and mature trees, and newer subdivisions to the north. Older homes are more likely to have weeping tiles or exterior drains connected to the sewer, which is the work Halton Region's subsidy is designed to fix. Mature trees also mean roots in older sewer laterals.
