What this service can—and cannot—address
Protect storm or sanitary laterals from an accessible exterior installation point.
- Excavation depth, utilities and soil conditions affect scope.
- Not every municipal subsidy covers exterior valves.
- Access lids must remain visible and protected after landscaping.
Flood Ready separates observations from assumptions, identifies permits and municipal-programme requirements, and documents the work included in the quotation.

Frequently asked questions
Clear answers before you book
Why install a valve outside?
An exterior location can provide access to the building lateral without opening an interior floor, but suitability is property-specific.
Can two valves be installed?
Some properties have separate storm and sanitary laterals. Any dual-valve recommendation requires inspection and programme review.
Is exterior work eligible in Markham?
Markham currently lists eligible outdoor storm or sanitary backwater valves under its programme, subject to pre-approval and other requirements.
Is exterior work eligible in Halton?
Halton’s current application states that backwater valves must be installed inside the home to qualify for that subsidy.
