What Homeowners Don’t Think About Before a Renovation: DSS Testing
Planning a kitchen renovation, home addition, or main-floor reconfiguration in the Kitchener-Waterloo region? You’re probably thinking about layouts, finishes, and how your family will use the space. But there’s one important detail many homeowners overlook: what’s hiding behind the walls, beneath the floors, and inside the materials of an older home.
For homes built before 1990, Designated Substances Survey (DSS) testing is an important step to consider before construction begins.
Why does this matter to you? Identifying hazardous materials early helps protect your family’s health, keeps your renovation on track, and helps you avoid unexpected costs, delays, and potential liability once construction begins.
What Is DSS Testing?
A DSS helps identify hazardous materials that could be disturbed during renovation or demolition, including asbestos-containing materials, lead, and other designated substances such as silica.
In older homes, these materials may be found in flooring, insulation, drywall compounds, and other building materials. Depending on the materials present and the work being completed, renovation activities can release hazardous dust or fibres into the air, potentially exposing homeowners, workers, and tradespeople. Identifying these materials early helps us plan the work properly, avoid unexpected delays, and protect your family and everyone involved.

Older Homes in Waterloo Region: What You Should Know
We regularly work in established Kitchener-Waterloo neighbourhoods, including East Ward, Westmount, and Beechwood, where many homes were built before 1990. From century homes full of character to older homes ready for a modern update, these properties often come with unique considerations that aren’t always visible at first glance.

Ontario’s Ministry of Labour (MOL) has requirements for identifying and managing hazardous materials on applicable renovation projects. For older homes, DSS testing helps identify materials such as asbestos, lead, and silica before they’re disturbed, helping protect your family and construction team while ensuring the work meets applicable safety requirements.
Both homeowners and contractors have responsibilities when it comes to workplace safety. Failing to address required testing and precautions can result in work stoppages, unexpected costs, and delays.
Not every older home contains hazardous materials, but identifying potential risks before construction begins helps everyone understand what needs to be addressed. Whether you’re renovating a kitchen, opening up your main floor, or building an addition, planning ahead helps protect your household and keeps your project moving with fewer surprises.
From Testing to Abatement, We Help Manage It
Finding hazardous materials doesn’t necessarily mean your renovation has to stop. It means the right steps need to be taken before work proceeds.

At Eagleview Construction, we work with trusted partners who specialize in asbestos abatement, helping ensure identified asbestos-containing materials are handled appropriately. Our team also understands how to manage project considerations involving lead and silica, with appropriate precautions and qualified specialists where required.
The goal isn’t to create unnecessary concern about your home. It’s to understand what we’re working with, determine what precautions or specialized services are needed, and address those requirements before construction gets underway.
Knowing what we’re dealing with before construction begins helps protect your family, our team, and the trades working in your home.
