Basement Renovations & Finishing in Stratford, St. Marys, Tavistock & Mitchell
A well-designed basement can dramatically increase the usable space in your home. Instead of a dark storage area, your lower level can become a warm, comfortable extension of your main floor. CJS Carpentry specializes in basement renovations and finishing projects that turn underused areas into functional living space for families across Stratford, St. Marys, Tavistock and Mitchell.
Whether you’re starting with a completely unfinished basement or updating an older, dated space, we bring structure, organization and craftsmanship to every project.
Make the Most of Your Basement
Every homeowner has different goals for their basement. Some want a cozy family room, others need extra bedrooms or a dedicated home office. During our initial visit, we’ll walk through the space with you and talk about:
- How you’d like to use the basement (rec room, bedrooms, gym, office, suite, etc.)
- Any existing moisture, insulation or comfort issues
- Headroom, natural light and window placement
- Storage needs and mechanical locations
- Your budget and desired timeline
From there, we develop a realistic plan that addresses both the visible design and the behind-the-scenes construction details.
Full-Service Basement Renovation & Finishing
Basement projects involve multiple trades and careful sequencing of work. CJS Carpentry takes a full-service approach, coordinating each step so your renovation is efficient and well-managed.
Framing & Layout
We start by framing new walls, bulkheads and room divisions according to your approved layout. Proper framing ensures straight walls, solid backing for drywall and fixtures, and clean transitions to existing structures. We also plan for door placements, closets and future furniture arrangements.
Insulation, Vapour Barriers & Sound Control
Basements require special attention to comfort and moisture control. We install insulation and vapour barriers that are appropriate for below-grade spaces, helping to keep your basement warmer in winter and cooler in summer. Where needed, we can also incorporate sound-dampening materials between floors or between specific rooms such as bedrooms or media rooms.
Electrical, Plumbing & HVAC Coordination
Most finished basements require electrical and sometimes plumbing and HVAC adjustments. As part of your project we can:
- Add outlets, lighting, switches and dedicated circuits
- Provide wiring for internet, TV and speakers
- Rough-in or relocate plumbing for bathrooms, bars or laundry
- Adjust ductwork and heat runs to improve comfort
Everything is planned with future use in mind, so the basement is convenient and comfortable once complete.
Drywall, Taping & Finishing
Once the infrastructure is in place, we install drywall, tape joints and sand for a smooth, paint-ready surface. Attention to detail at this stage is crucial — straight corners, clean lines and proper finishing all contribute to a professional-looking result.
Flooring & Trim
The right flooring makes your basement feel like a true living space. We install materials suited to lower levels, such as luxury vinyl plank, carpet tiles, laminate or tile. Finally, we complete the space with baseboards, casings, doors and other trim work to match the character of your home.
Basement Spaces We Commonly Create
Basements are versatile. We regularly help homeowners create:
- Family and rec rooms
- Home theatres and media rooms
- Guest or children’s bedrooms
- Home offices and study areas
- Workout rooms or home gyms
- Playrooms for kids
- Hobby or craft spaces
- Organized storage rooms and utility areas
If you’re considering a basement suite for family use or potential income, we can also frame and finish separate living areas with bedrooms, bathrooms and kitchenettes, ensuring proper fire separation and privacy where required.
