What We Include for Basement in St. Catharines
Basement Finishing
Transform your unfinished basement into a livable space. Framing, insulation, drywall, flooring, and paint, done right, on schedule, with moisture and ventilation handled for Niagara’s climate.
Secondary & In-Law Suite Layouts
Many Niagara homeowners want a private basement area for parents, adult children, or long-term guests. We plan separate entrances, sound separation, kitchenettes, and bathrooms where your layout allows. If you need a fully legal rentable suite with code rated fire separation and egress, our Legal Secondary Suites service covers permit driven scope. We can connect finishing work to that pathway.
Rental Income Potential
A finished basement apartment can help offset your mortgage when it is legal and insured. Rents vary by city and finish; many landlords use broad benchmarks around $1,500 to $2,500 per month for a one-bedroom basement unit before expenses. We do not guarantee rents. Confirm with local listings and your accountant.
Government Financing & Lending (Verify Current Programs)
Federal and provincial initiatives have sometimes supported adding secondary units; product names, caps, and eligibility change. Some homeowners use refinance or renovation loans. We are your build partner, not a lender. Check official government and bank pages, and talk to a mortgage specialist before you budget.
Basement Bathroom & Wet Bar
Add a bathroom, wet bar, or both. We handle plumbing, tiling, fixtures, and ventilation so your basement stays comfortable and inspection ready.
Basement finishing: how budgeting works in St. Catharines
- Open finishing (rec room, office, basic bath): varies widely by size and finishes
- Adding a bathroom, wet bar, or partition walls increases scope and plumbing costs
- Legal secondary suites require rated assemblies, egress, and inspections. Budget significantly above basic finishing
