Basements hold massive potential—but only if they’re properly finished. Whether you’re dreaming of a family room, guest suite, income apartment, or personal gym, a well-done basement renovation can dramatically increase both your living space and property value.
But here in Sault Ste. Marie, basements come with their own set of unique challenges. From cold winters and high water tables to older foundations and dated building codes, careful planning is key to a successful reno.
Here’s what you need to know before diving in.
🧱 Step 1: Assess the Condition of Your Basement
Before planning anything cosmetic, it’s critical to check for moisture, cracks, insulation, and ventilation. Even the best design won’t last if your basement has hidden issues behind the walls.
Look out for:
-
-
Water stains or damp spots
-
Musty smells (a sign of poor ventilation or mold)
-
Cracks in the foundation or floor
-
Drafts from basement windows
-
Local Tip: Many older homes in Sault Ste. Marie were built before modern moisture barriers or insulation standards were common. That means retrofitting may be necessary.
🧰 Step 2: Decide on the Purpose of the Space
How you plan to use your basement determines your entire renovation approach.
Here are some popular uses:
-
-
Family/Rec room – Add cozy flooring, lighting, and open layout
-
Rental unit – Requires full kitchen, bathroom, separate entrance, and egress windows
-
Home office or gym – Needs soundproofing and dedicated outlets
-
Guest suite – Requires thoughtful layout and possibly a second bathroom
-
Whatever your goal, keep resale in mind too. Multi-use spaces that can serve as bedrooms, offices, or living areas tend to add the most value.
📐 Step 3: Plan Your Layout and Features
This is where your vision comes to life. Once you know what you’re building, create a layout that uses the space efficiently. Key features to consider include:
-
-
Lighting – Basements often lack natural light, so go heavy on pot lights or bright fixtures
-
Ceiling height – Be mindful of ductwork and building code minimums (at least 6’5” clearance)
-
Soundproofing – Especially important if you’re building a rental or entertainment room
-
Storage – Add built-ins or under-stair storage to keep things tidy
-
Pro Tip: In Sault Ste. Marie, basement bedrooms must have egress windows to meet code. If you’re planning to add a bedroom, make sure your window size and placement are compliant.
💧 Step 4: Waterproof and Insulate Properly
No matter how beautiful your finished basement looks, it won’t last if it isn’t dry and warm.
Essential upgrades include:
-
-
Interior or exterior waterproofing membranes
-
Sump pump and weeping tile systems
-
Rigid foam insulation or spray foam
-
Proper vapor barriers and subfloor systems
-
Local Tip: With Sault’s freeze-thaw cycles, it’s worth getting a moisture inspection or working with contractors who know how local soils and weather impact foundations.
📄 Step 5: Know the Permits and Codes
Basement renovations often require permits—especially if you’re altering plumbing, electrical systems, or adding a rental unit. In Sault Ste. Marie, you may also need zoning approval for certain conversions.
Don’t risk skipping this step:
-
-
You could face fines or forced demolition
-
It may impact future home sales or insurance claims
-
Unpermitted work can void mortgage approvals
-
