Basement Waterproofing in North York
Our shop is on Consumers Road, so North York is home ground. We are usually there in minutes rather than the hour.
North York runs from 1950s and 60s bungalows through Don Mills post-war planning to the condo towers along Yonge and Sheppard. The older stock has original clay drains and unfinished or owner-finished basements.
Most North York callouts are sump pump failures, backed-up floor drains in the older bungalows, and burst supply lines in the Yonge corridor towers.
Cleaning up a flood twice is a choice. Once the property is dry, the useful question is why the water got in and what it would cost to keep it out.
Covered by insurance? We bill your insurer directly, so in most cases you pay only your deductible.

When to call us in North York
After the drying is finished, or before spring thaw if you already know you have a problem. It is the one part of this work you get to schedule rather than have forced on you.
What basement waterproofing in North York costs you
We bill your insurance company directly. On most covered losses that is the only amount you pay us.
Water damage is the most common home insurance claim in Ontario, and the great majority of the work we do is paid by an insurer rather than by the property owner. We document every loss from the first hour with moisture readings, photographs and a written scope, which is the evidence an adjuster needs to approve the work without argument or delay.
We work with all major Canadian insurers and handle the claim from start to finish, including the adjuster's questions. If you are not insured, or the loss falls outside your policy, we will give you a clear written quote before any work begins and we will tell you honestly what can be dried and saved rather than replaced. Keeping material in place is what keeps the cost down, and it is the first thing we look at.
There is no charge for attending to assess an emergency, and no obligation once we have. What your policy covers →

How the insurance side works
Water damage is the most common home insurance claim in Ontario, and how the claim is handled usually matters more to your bill than the work itself. We document the loss from the first hour: moisture readings, photographs, a written scope, and a daily drying log. That is the evidence an adjuster needs to approve the work without arguing about it.
We bill your insurer directly. In most cases the only money you hand over is your deductible, which on Ontario policies commonly sits between $500 and $2,500.
Which losses are covered depends entirely on where the water came from. A burst pipe or a failed appliance is normally covered under a standard policy. Water coming up through a floor drain is sewer backup, which is almost always a separate endorsement you have to have purchased. Water entering from outside during heavy rain is overland flood, which is another endorsement again. A single storm can produce all three at once, which is why adjusters care so much about the source.

Common questions
How quickly can you reach North York?
Our shop is on Consumers Road in North York, so this is the fastest area we serve. In most cases we are on site well within 45 minutes.
Do you work in the Yonge and Sheppard condo towers?
Yes. We handle in-suite losses and water that has travelled between floors, and we coordinate access with building security and property management.
What is a backwater valve?
A one-way valve fitted on your sanitary line that closes if the municipal sewer surcharges, stopping sewage entering the house through floor drains and toilets. It is the standard protection against sewer backup.
Does the City of Toronto pay for it?
The Basement Flooding Protection Subsidy Program offers up to $6,650 per property toward eligible flood protection work for single-family, duplex, triplex and fourplex homes. Terms change, so confirm the current amount and eligibility on toronto.ca.
Interior or exterior waterproofing?
Exterior addresses water before it reaches the wall and lasts longest, but it means excavation and it costs more. Interior systems manage water that has already entered and are less disruptive. Which is right depends on the foundation and the source.
Do I need a battery backup on my sump pump?
In the GTA, storms and power cuts arrive together. A sump pump without backup power is a pump that stops working at the moment you need it.
