Basement Bedroom Addition in Wexford
Professional basement bedroom addition services for Wexford homeowners. Licensed, insured contractors serving the East Toronto area.
What Is Basement Bedroom Addition?
A basement bedroom addition is the construction of a habitable sleeping room in a below-grade space that meets Ontario Building Code requirements for egress, ventilation, ceiling height, and heating. The code requires an egress window with at least 3.8 square feet of unobstructed opening, a minimum ceiling height of 6 feet 5 inches, and adequate heating to maintain 22 degrees Celsius. In Toronto and the GTA, basement bedroom additions cost $45 to $90 per square foot, with egress window installation adding $3,500 to $6,000 if the existing window is undersized.
Basement Bedroom Addition for Wexford Homes
Homeowners in Wexford trust Renovation Basements for professional basement bedroom addition projects. With homes in this area typically 1950s-1970s, many residents are investing in transforming their underutilized basement spaces into valuable living areas.
Adding a bedroom to your basement is a practical and cost-effective way to expand your home's sleeping capacity without the expense of a building addition. Whether you need an extra room for a growing family, want to create a private guest suite, or are building a legal basement apartment, a properly constructed basement bedroom provides comfortable, year-round accommodations. However, basement bedrooms carry specific Ontario Building Code requirements that differ from above-grade bedrooms — most notably egress window regulations that ensure safe emergency exit. Ceiling height, ventilation, smoke detection, and fire separation requirements must also be met for the room to be legally classified as a bedroom. At Renovation Basements, we specialize in designing basement bedrooms that meet every code requirement while maximizing comfort, light, and livability. Our designs address the inherent challenges of below-grade sleeping spaces — limited natural light, potential moisture, sound transfer from above — with proven solutions that create rooms people genuinely enjoy using every night.
About Wexford
Wexford is a well-established Scarborough neighbourhood with post-war bungalows and 1960s homes. Clay-dominant soils hold moisture against foundations, and the flat terrain allows water to pool without proper grading. Many long-time homeowners are investing in basement renovations to age in place, adding accessible bathrooms and living areas. The area affordable prices relative to central Toronto make basement finishing a strong return on investment.

Our Basement Bedroom Addition Process in Wexford
Every basement bedroom addition project in Wexford follows our detailed process to guarantee quality results.
Code Compliance Assessment
We evaluate your basement for bedroom eligibility — ceiling height, existing window sizes, heating capacity, and available space. We identify what modifications are needed to meet Ontario Building Code requirements and develop a plan that addresses every requirement.
Egress Window Planning & Permits
We design the egress window installation, including the window size, window well dimensions, and foundation cutting required. Building permits are submitted with detailed drawings showing the bedroom layout, egress compliance, ventilation, and fire safety measures.
Foundation Cutting & Window Installation
If a larger window is required, we carefully cut through the concrete foundation wall, install a properly sized egress window, and construct a code-compliant window well outside. The window well includes a drainage system to prevent water accumulation and a ladder or step system if the well depth exceeds 24 inches.
Framing, Insulation & Soundproofing
Bedroom walls are framed and insulated with closed-cell or rigid foam insulation for thermal comfort and moisture resistance. The ceiling is built with resilient channel and acoustic insulation to minimize sound transfer from the floor above. Vapour barriers are installed to manage moisture.
Electrical, HVAC & Drywall
Electrical circuits provide outlets on each wall, overhead pot lights, and bedside switch-controlled lighting. HVAC supply and return are verified or added to ensure the room reaches the required temperature. Drywall is installed, taped, and finished on all surfaces.
Finishing, Closet & Final Inspection
Flooring, trim, paint, and closet construction complete the room. A hollow-core or solid-core door with proper hardware is installed. Smoke and carbon monoxide detectors are positioned per code. Municipal inspection verifies all code requirements are met.
Why Wexford Homeowners Choose Us
Affordable Extra Sleeping Space
A basement bedroom costs a fraction of a home addition while providing a fully functional, private sleeping space. At $45 to $90 per square foot, a 150 square foot bedroom costs $6,750 to $13,500 — compared to $200 or more per square foot for an above-grade addition.
Enable Legal Apartment Use
A code-compliant bedroom with proper egress is essential for any legal secondary suite in Ontario. Without it, your basement apartment cannot be registered, leaving you exposed to liability and unable to command market-rate rent.
Multi-Generational Flexibility
A basement bedroom provides private accommodation for aging parents, adult children, or extended family members. Combined with a bathroom, it creates a self-contained suite that preserves everyone's independence while keeping the family together.
Increase Your Home's Bedroom Count
Real estate listings in the GTA prominently feature bedroom count. Adding a legal basement bedroom transforms a 3-bedroom home into a 4-bedroom home on paper, which significantly impacts listing appeal and market value.

Basement Bedroom Addition FAQ for Wexford Homeowners
What are the code requirements for a basement bedroom in Ontario?
The Ontario Building Code requires basement bedrooms to have a minimum ceiling height of 6 feet 5 inches, an egress window with at least 3.8 square feet of unobstructed opening and no dimension less than 15 inches, the window sill no higher than 3.3 feet from the floor, a minimum room size of approximately 75 square feet, at least one electrical outlet on each wall, smoke detection, adequate heating to maintain 22 degrees Celsius, and proper ventilation. If part of a secondary suite, additional fire separation and carbon monoxide detection requirements apply.
How much does a basement bedroom cost in Toronto?
A basement bedroom addition in Toronto typically costs $6,000 to $18,000 depending on the scope. A basic bedroom with existing adequate window and ceiling height costs $4,500 to $9,000 for a 100 to 150 square foot room. If an egress window must be installed, add $3,500 to $6,000 for the window and well. Soundproof ceiling upgrades add $1,500 to $3,000. Premium finishes with walk-in closet, hardwood flooring, and built-in storage push the total to $12,000 to $18,000.
Do I need an egress window for a basement bedroom?
Yes. The Ontario Building Code and the Ontario Fire Code both require an emergency escape window in every basement bedroom. This is a non-negotiable safety requirement. The window must provide an unobstructed opening of at least 3.8 square feet with no single dimension less than 15 inches. If your existing basement window does not meet these requirements, it must be enlarged or a new window must be installed. This typically involves cutting through the concrete foundation wall and constructing an exterior window well.
How do you keep a basement bedroom warm?
We ensure basement bedrooms meet the code-required 22 degrees Celsius through several approaches. Proper insulation with closed-cell or rigid foam on foundation walls prevents heat loss through concrete. HVAC supply and return registers are installed or extended to provide forced-air heating. If the existing furnace cannot adequately reach the basement bedroom, supplemental heating options like electric baseboard heaters or in-floor heating are considered. Insulated exterior walls and windows with double or triple glazing minimize thermal bridging.
How do you reduce noise in a basement bedroom?
Sound transfer from the main floor above is the most common complaint about basement bedrooms. We address this using a combination of resilient channel (metal strips that decouple the ceiling drywall from the floor joists), acoustic insulation batts between joists, and double layers of drywall where maximum sound reduction is needed. These measures together can reduce sound transfer by 15 to 20 decibels, which is the difference between clearly hearing footsteps and conversations above versus barely noticing activity on the main floor.
