Weeping Tile Installation

Sometimes weeping tile systems get clogged or damaged. Especially old clay pipe installations that most old Toronto houses have. Interhome Waterproofing offers weeping tile replacement and installations. Installing a weeping tile is an integral piece of the waterproofing system. An interior or exterior weeping tile system is installed to collect water from heavy rainfall or snowmelt that accumulates at your foundation footings. The water is drained into the weeping tile pipe and then discharged away from the property.

Sump Pump Installation

Installing a basement sump pump could be the most important thing you can do to prevent flooding. If your property is in a low-laying area that is prone to flooding then investing in a sump pump system will save you money. Modern sump pumps have alarms, text and email notifications and even backup pumps. You can be immediately informed about your basement being flooded by the sump pump system. We offer a free on-site assessment and we can educate you on the latest and best sump pump devices.

Testimonials

Laura Matheson

Home Owner, Markham

"I just wanted to thank you again for the excellent work your guys did and your very high level of service. You went above and beyond in a number of areas and that is unfortunately pretty rare in the construction industry today. Thanks again.

John O’Connor

Home Owner, Toronto

“Interhome Waterproofing is at the top of their field. We had a wet basement issue and had a few contractors come out for an assessment. Very quickly we were impressed by Ali, one of the owners of IW. He was thorough, patient to explain to us our options, even pointed out that our sump pump was not working properly. We are very pleased with their work. They were professional, courteous and the project manage was always on top of things. Highly recommended.”

Leo Boico

Nabeel Construction, Toronto

“As general contractors we rely on our working relationship with our sub-contractors to produce quality work and uphold our good name. We have been working with Interhome Waterproofing since 2008. They have tackled several complex projects and have always delivered on time and above expectations. We value having them as partners and look forward working with them on our next project.”

Gus Leonidis

Home Owner, Toronto

"Interhome Waterproofing came highly recommended by our building engineer and we are so glad we took his recommendation. We decided it was time to add a full height basement to our old Toronto house. The underpinning process scared us, but Ali put our fears to rest by thoroughly explaining the safeguards and precautions that their process included. The project went without a hitch and we are very happy with the result and their service."
