Cost of Foundation Weeping Tile Installation from Inside of House.

Good evening,

The cost of interior waterproofing is calculated by linear feet. To waterproof your house is going to cost 9000$. City of Toronto will rebate 1750$ for installation of the sump pump. That brings the cost down to 7250$. Grading is not going to help a lot and can be done only after waterproofing. (Just to reduce the amount of water that goes towards the foundation wall)

If your basement is 6ft. I will suggest you to underpin it to get 8 feet ceilings. Underpinnig includes interior waterproofing and for your house might cost around 35000$ to 45000$.

Best regards,

Alex

Hello David, my name is Wayne Nesbeth of H2O Services Corporation. As per your post we would need to see the property in question, however based on your description the ballpark pricing would be $9500.00 to excavate and lay internal weep tile to a sump pit. We specialize in backwater valves and sump pump systems. The city of Toronto is offering up to $3400.00 in subsidies to install flood prevention devices.

Hi David, thanks for asking a good question. In terms of interior waterproofing your looking at around $60-70 per liner foot of your basement if its unfinished and has no drywall or studs. if its finished basement then demo of needed walls and flooring with take place as well, for this kind of job your price range is about $100 per liner foot including demolition and disposal. given the dimensions you provided the cost would be $5640-$6580 for unfinished basement and $9400.00 for finished basement that needs demo.

Also as your are doing interior waterproofing you would need to install a sump pump. I provide Liberty 237 sump pump with Liberty sealed pit. discharge to outside. cost around $2200.00

This job will also qualify for a City of Toronto rebate of $1750.00 for Sump pump and Severance capping rebate of $400.00. Total Rebate $2150.00

Thanks
