Interhome Waterproofing was formed in 2004 by two brothers that come from a long line of tradesmen. Armed with the experience of working for their grandfather’s construction company since they were teenagers, they decided it was time to create something of their own.

Today, Interhome Waterproofing is a family run business. Both owners and their tradesmen take pride in their work and love helping families improve and protect their homes and properties. Waterproofing and underpinning are not cosmetic additions to someone’s home. They are investments that can provide protection from water damage, strengthening of the structural integrity, the addition of liveable space for their family or a rental income. They can also increase property values.  We respect our clients’ investment, both on their property and investing their trust in our services.

Our core values are integrity, craftsmanship and customer service. Construction projects in general have complexities. Our goal is to use our experience and expertise to forsee complications and quickly trouble shoot, and resolve, when things go wrong.

Safety for our crew, our clients and their families is also important to us. We carry liability insurance and WSIB coverage. We are licensed and we are knowledgeable on required city permits and inspections.

We would like to thank all our clients for choosing us and helping us grow to the company we are today. We are also proud for our network of partners and the long-lasting business relationships we have cultivated together. We look forward working on your future project, call us today to schedule a free on-site assessment.

Proudly Canadian!

"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.”

“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.”

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."
