Tailoring Your Basement to Perfection
Buried beneath many Toronto homes is untapped square footage just waiting to be reimagined.

Results like these don’t come from DIY attempts or generic contracting. The difference lies in experienced professionals who know local building codes, waterproofing essentials, structural limits, and modern design. True Form Construction delivers that advantage—combining in-house trades with custom planning to maximize both function and finish.

Unlock More Space Below
A basement is a blank canvas. They usually are larger, flat spaces with more than one room, and can be transformed into essentially any space you’d like. The key to a successful basement renovation is, no matter what you decide to transform into, it should be a space you genuinely want to spend time in.
Add Valuable Square Footage
Real estate isn’t getting cheaper in Toronto, but your basement already exists. Renovating below grade adds usable square footage without changing your home’s footprint. For homes in space-constrained neighbourhoods—from Leslieville to High Park—this makes basement renovations a direct path to more room and higher property value.
According to a 2023 report by the Appraisal Institute of Canada, well-executed basement renovations can deliver a return on investment (ROI) of 50–75%, depending on finishes and use-case. That’s space that doesn’t just serve—it pays back.
Transform Wasted Space
Basements often become storage zones filled with forgotten items. A smart renovation replaces boxes with function. Outdated drywall, cold concrete floors, and low-hanging wires turn into livable, purposeful areas. Imagine converting that underutilized square footage into a media room, gym, or walk-in pantry that supports daily life.
With a full-service transformation, every inch below your floorboard earns its keep.
Multi-Purpose Functionality
How would you use an extra 600 to 1,000 square feet? Home theatres with integrated surround sound. Executive-level offices with dedicated lighting and Ethernet access. Stylish guest suites with spa-inspired bathrooms. Or perhaps a fully outfitted basement apartment earning $1,500–$2,500/month in passive income, depending on location and features.
True Form Construction designs for function first—then tailors every detail to your goal, whether it’s hosting in-laws or tenants.
Designed for Growing Families
Toronto families stretch homes to accommodate evolving needs—teens needing space, grandparents moving in, or young professionals returning to the nest. A finished basement offers elegant solutions for multi-generational living. Separate bedrooms, distinct entrances, and sound-insulated walls provide privacy without isolation.
- Private space for older children or parents
- Second kitchen options for independence
- Multi-zone HVAC for inpidual comfort
Whether your household is expanding or simply transforming, the basement becomes part of the solution—not a forgotten section of the past.

Waterproofing That Lasts Decades
Toronto’s Unique Basement Risks
Toronto basements face heavy spring thaws, freeze-thaw cycles, and clay-heavy soil that retains water. Combined, these conditions increase hydrostatic pressure against foundations, pushing moisture and even groundwater into basements. At True Form Construction, we complete a full assessment of your property’s drainage patterns, foundation type, and elevation to detect every water intrusion risk.
Effective Multi-Layered Waterproofing
We don’t rely on one method. Our approach combines the most durable systems to keep basements dry.
- Sump Pump Installation: We install submersible sump systems with battery backups to ensure flooding never reaches your finished spaces—even during blackouts.
- Interior Waterproofing: This includes weeping tiles, drainage membranes, dimpled air gap barriers, and water-resistant wall panels that redirect moisture safely into the drainage system.
- Exterior Waterproofing: Where accessible, we excavate around the foundation, repair cracks, install new damp-proof membranes, and apply high-grade elastomeric coatings. This dramatically reduces lateral pressure on basement walls.
Mold Prevention by Design
Moisture invites mold—and mold undermines everything. To combat this, we use water-resistant materials throughout. Our projects integrate mold-resistant drywall, closed-cell spray foam insulation, and flooring designed for below-grade installation. Strategic dehumidifier placements help maintain low humidity even in humid summer months.
Dry Basement, Long-Term Confidence
Choosing long-lasting solutions upfront eliminates ongoing maintenance and expensive repairs later. Every waterproofing strategy we use supports your renovation goals. No surprises. No water damage. Just a dry, healthy basement you can enjoy for years.
Legal Basement Apartments
Earn Rental Income at Home
Turning a basement into a legal secondary suite in Toronto opens the door to stable monthly income while increasing your property’s value. Homeowners across the city are unlocking thousands of square feet hiding beneath their main floors—space that renters actively seek in high-demand neighborhoods. With market rents ranging from $1,700 to over $2,500 per month for basement units in Toronto (Toronto Regional Real Estate Board, Q1 2024), the potential for smart long-term return is clear.
Full Legal Compliance
Toronto zoning bylaws and building regulations outline strict rules for second suites, and compliance isn’t optional. We manage every aspect, including:
- Zoning review and planning: Confirming eligibility based on municipal zoning and lot dimensions.
- Building permits secured: Submitting plans, coordinating with city officials, and ensuring timely approvals.
- Final inspections: Guaranteeing all work passes with no delays or unpaid rework.
We handle the red tape from start to finish, with zero unexpected surprises.
Fire Code and Soundproofing
Legal second suites must include top-tier fire protection and proper acoustic separation. We install:
- 30-minute fire-rated ceiling assemblies
- Interconnected hardwired smoke and CO alarms
- Fire separation between units in walls and mechanical penetrations
- STC-rated insulation and resilient channels to dampen footstep and voice noise
This work doesn’t just satisfy inspectors—it creates a safer, quieter living space for both households.
Bedrooms, Kitchens, and Egress
We don’t retrofit illegally. Our team builds fully functional suites with all required elements:
- Dedicated kitchen with separate appliances and ventilation
- Bathroom facilities with appropriate drains and plumbing venting
- Minimum ceiling height of 1.95 m (6 ft 5 in)—as required by Toronto code
- Proper egress windows for every legal bedroom, with window wells and emergency access
- Independent electrical panels or subpanels with unit-specific metering if requested
Every utility, exit route, and room passes both planning scrutiny and the expectations of a future tenant.
Custom Design That Works
Open Layouts That Flow
Rigid walls and awkward corners limit potential. An open-concept basement layout changes the experience of the space entirely. It increases usable square footage, improves natural light distribution, and creates better airflow. True Form Construction removes unnecessary barriers, carefully planning structural supports and sightlines to open the room while preserving the integrity of your home.
Want a walk-up bar that connects seamlessly to your media room? Or maybe a reading nook that doesn’t feel tucked away? Our team makes it work.
Interior Style That Reflects You
Design without direction leads to results that feel generic. That’s why every Toronto basement renovation by True Form begins with conversations about tone, mood, and purpose.
- Colour palette consultations to build atmosphere
- Custom millwork to add personality and cohesion
- Furnishing layouts designed around function, not trends
From modern minimalism to heritage warmth, the finished look aligns with how you’re going to live in it.
Basement Spaces Transformed
No more excuses. With rubber floors, mirrored walls, and smart ventilation systems, your personal gym sits just a stairway away. Customize it with cardio machines, free-weight zones, or even a wellness space with infrared sauna and yoga studio.
During Toronto’s long winters, skipping the drive to the gym becomes one less obstacle. Everything you need to stay healthy stays right at home.
Basement Bathrooms Done Right
Smart Layouts, Full Function
A bathroom in the basement doesn’t need to feel like an afterthought. Whether it’s a compact powder room, a three-piece guest bath, or a full ensuite with spa features, the layout drives the experience. True Form Construction tailors the design to fit the unique footprint of your basement. Tight corners, low ceilings, or utility bulkheads—nothing gets in the way of building a bathroom that delivers both function and flow.
Optimized Use of Space
No square foot goes to waste. Creative plumbing rough-ins, recessed shelving, and wall-hung fixtures open up cramped areas. Sliding doors and corner vanities free up circulation room. Our design-build team reconfigures under-stair nooks and odd-shaped utility enclosures into usable, attractive bathroom zones.
Finishes That Elevate
- Porcelain tiles that mimic natural stone without the maintenance
- Floating vanities paired with seamless quartz counters
- Modern plumbing fixtures in matte black, brushed gold, or polished chrome
- Curbless showers with linear drains for a sleek, barrier-free look
Refined materials don’t just add style—they also improve durability and make cleaning easier in high-humidity spaces.
Total Comfort, Built In
Good bathrooms go beyond layout and finishes. Heated flooring adds warmth from below, especially during Toronto’s long cold season. Our builds include efficient exhaust systems that move moisture out and keep the air balanced. Upgrades like built-in Bluetooth speakers, LED mirrors, and dimmable lighting put luxury within reach without expanding the footprint.
Build With Confidence
Plumbing systems in basement bathrooms need expert handling. Drainage angles, venting, and backflow prevention are non-negotiable. True Form Construction coordinates every element with licensed trades and city inspections to avoid future issues and guarantee compliance. Each bathroom is engineered to last and designed to impress.
Smart Storage, Seamless Utility
Built-Ins That Maximize Space
Toronto basements demand practical use of every square foot. True Form Construction integrates custom built-in solutions that turn unused areas into functional storage. Under-stairs compartments, full-height wall units, and flush cabinetry all serve a dual purpose—elegance and efficiency.
- Under-stairs storage: Precision carpentry transforms dead space beneath staircases into drawers, shelves, or hidden cupboards perfect for seasonal items, footwear, or cleaning supplies.
- Wall-integrated systems: Floor-to-ceiling shelving units provide unobtrusive organization without consuming valuable floor area.
- Concealed cabinetry: Push-latch doors and soft-close hinges maintain a clutter-free visual while keeping essentials out of sight.
Multi-Use Utility Spaces
There’s no sense in dedicating an entire room solely to laundry or mechanical systems if those zones can work harder. True Form Construction designs dual-purpose layouts that incorporate HVAC access, electrical panels, and water heaters discreetly into laundry or utility rooms.
- Stacked washer-dryer setups leave space free for utility sinks or folding counters.
- Custom enclosures mask mechanical units while preserving full-service access for technicians.
- Overhead shelving and vertical pegboards increase light-duty tool and cleaning supply storage.
Declutter with Intelligent Design
No one wants to see bins, wires, or boxes strewn across the floor. Integrated hidden storage elevates the look of every renovated basement. Expect seamless panels that camouflage storage zones, wall niches that double as art displays, and flip-up benches that reveal deep compartments underneath.
Every inch counts in a Toronto basement. By maximizing vertical surfaces, empty corners, and transitional zones, you eliminate bulk and gain usable square footage. Imagine zero clutter—just clean lines and smart functionality crafted to match your lifestyle.
Soundproofing and HVAC
Block Out Unwanted Noise
Noise from above can disrupt the flow and feel of a finished basement. True Form Construction applies proven soundproofing methods to ceiling and wall assemblies to significantly reduce airborne and impact noise. Whether you plan to rent out your basement or create a secluded retreat, minimizing sound transfer adds value and comfort.
- Between-floor insulation: We use acoustic mineral wool and resilient channel systems to isolate vibrations and block sound.
- Wall soundproofing: Double stud framing, mass-loaded vinyl, or sound-dampening drywall options ensure privacy within multi-use spaces.
- Sealed penetrations: Electrical and plumbing intrusions are sealed meticulously to avoid acoustic leaks.
Integrated HVAC Upgrades
Basement spaces demand precise climate control. We install systems tailored for lower-level airflow challenges, guaranteeing even circulation and balanced temperatures year-round.
- Dedicated ventilation lines: Fresh air supply ensures low humidity and better indoor air quality.
- Zoned heating and cooling: Multi-zone thermostats give separate control over basement temperatures without overloading the main system.
- High-efficiency duct layouts: Optimized duct runs reduce energy loss and improve performance—essential in enclosed spaces.
Electrical Panel Expansion
Basement renovations often require more circuits for lighting, heating, or appliances. Our licensed electricians upgrade or reconfigure your panel to accommodate additional electrical load safely and to code.
- New subpanels: When needed, we install subpanels dedicated to the basement area for clean distribution and reliability.
- Capacity assessments: Detailed calculations match your renovation needs with the right panel upgrade, preventing overloads.
A Space That Breathes Comfort
Temperature, humidity, and acoustics work together to define the feel of a space. Through advanced HVAC configurations and layered sound insulation, True Form Construction creates basements that feel connected, but not exposed. Thinking of converting your basement into a liveable suite or home studio? Let’s build it quiet, climate-friendly, and future-ready.
01
Set Realistic Milestones
Every basement renovation begins with a defined schedule shaped around your availability and vision. Our project managers map out specific stages—demolition, framing, plumbing, electrical, drywall, finishes—then assign timeframes based on your space and scope. A typical full basement renovation in Toronto takes 6 to 10 weeks. Smaller conversions, such as turning a basement into a home office or gym, wrap up faster, often within 4 to 6 weeks.
Want a wet bar by Thanksgiving or a legal basement suite for your tenants by spring? We lock in target dates and build around your life—not the other way around.
02
Clear Costs from Day One
Clients receive a fixed, itemized contract before the first hammer swings. This includes:
- Labour and materials – fully priced by square footage and selected finishes
- Permits and inspections – upfront government fees, no surprises
- Contingency line – built into every quote for unknowns discovered on-site
- Tax and warranty coverage – integrated, not added later
For homeowners working within a strict budget, we’ll offer cost-saving alternatives like laminate flooring over hardwood or engineered quartz instead of granite. Ugly surprises have no place in your renovation experience. Everything is quoted, signed, and scheduled at the start.
03
Upgrades and Phased Builds
Not ready to finish the entire basement in one go? We design modular renovation phases, so you can add features over time. Phase one might include waterproofing, framing, electrical rough-ins, and insulation. Phase two could build out the guest suite and storage. Phase three? A custom home theatre or wine room. Your project flows with your budget and pace.
04
Consistency with One Point of Contact
Every basement renovation with True Form Construction is assigned a dedicated project manager. This person—your central point of communication—walks the timeline with you from planning to finishing trim.
- Sends weekly photo and video updates
- Flags design and supplier decisions early
- Coordinates permits, inspections, and deliveries
- Simplifies any mid-project edits or upgrades
No back-and-forth with multiple departments. No explaining the same request twice. Just one person, fully dialed into your project’s needs and schedule.
It Starts With Your Personalized Project Quote
Explore your ideas. Ask questions. Dream bigger. We’ll handle the rest-from architecture to final handoff.
Framing, Drywall, and Waterproofing
Framing defines the flow of your basement. It lays the groundwork for every room and functional area, from storage spaces to entertainment zones. Our team precision-frames according to plan, ensuring square angles, level structures, and code compliance across every wall and bulkhead.
Once the frame is in place, we expertly install drywall using high-quality sheetrock, screw patterns that resist sagging, and taping methods that eliminate visible seams. Paired with waterproofing membranes and moisture-resistant sealants, your finished basement will resist Toronto’s common humidity fluctuations and ground moisture.
Insulation and Energy Efficiency
Thermal efficiency starts behind the walls. True Form Construction selects insulation materials that exceed Ontario Building Code R-value requirements, reducing heat loss and improving air retention. Closed-cell spray foam, mineral wool, or rigid foam board—each is chosen based on your basement’s conditions and your budget.
- Spray foam insulation: Creates an air-tight barrier that seals gaps and cracks.
- Mineral wool: Offers fire resistance along with high thermal performance.
- Rigid foam panels: Maintain insulation value even in damp spaces.
In combination with air sealing and weather-stripped entry points, our insulation methods lead to lower energy bills and better comfort year-round.
Durable Basement Flooring Options
Flooring in a Toronto basement can’t be an afterthought. Moisture, traffic, and thermal variation demand resilient materials. We install flooring systems that resist swelling, warping, and mold.
- Luxury vinyl plank (LVP): Waterproof, stylish, and warm underfoot when combined with an insulated subfloor.
- Tile: Ideal for laundry areas or bathrooms, offering unmatched water resistance.
- Engineered hardwood: A great compromise between comfort and resilience when air quality and humidity are well-controlled.
We also lay subfloor systems that create a vapor barrier, protect against cold concrete slabs, and extend the lifespan of the flooring above.
Interior Painting and Wall Treatments
Paint brings the room to life—but in basements, it also serves a protective role. We use coatings designed specifically for low-light, low-ventilation environments. Mold-resistant primers prevent mildew, while durable topcoats maintain color vibrancy year after year.
Looking for texture or visual depth? We craft accent walls with shiplap, reclaimed wood, or geometric paneling, enhancing aesthetic appeal and adding personality to each space.
Every brushstroke is applied by professionals committed to precision, ensuring corners are crisp, transitions are clean, and the finish reflects your vision in detail.
