Professional Basement Remodel Contractors Since 2011

divider

Total Renovations is a licensed general contractor and one of the region's most established basement remodeling companies, delivering basement renovation services since 2011. We build the full range of basement development — from straightforward basement finishing to complete legal secondary suite construction — and we carry every permit, inspection, and trade from the first walkthrough through to handover.

Basement renovation on the West Coast is a harder engineering problem than most of Canada. Depending on where you live, homes here absorb somewhere between 1,100 mm and 1,900 mm of rain a year. Clay-heavy soils hold that water against foundation walls instead of draining it away, and every municipality interprets the BC Building Code with its own bylaws, forms, and inspection culture. Corners cut during basement finishing don't show up as bad-looking work — they show up as a remediation invoice four winters later.

Whether you are pricing affordable basement remodeling or a premium legal suite build, the standard is the same on every project: measured design, a fixed line-item quote, licensed trades, and all permits pulled on your behalf. That combination is why homeowners keep calling us the basement renovation experts who got it right the first time.

Complete Basement Remodeling & Renovation Services
Design Through Final Inspection

Our basement renovation services cover every scope and budget — entry-level basement finishing through to full basement development with a legal rental suite. Here is every type of project our basement remodeling contractors build:

legal secondary suites
Legal Secondary Suites
Self-contained rentals with their own entrance, kitchen, full bathroom, egress windows, and dedicated ventilation — built to your municipality's legal suite bylaw so the income is compliant and the paperwork survives resale.
in-law nanny suites
In-Law & Nanny Suites
Multigenerational living that actually works day to day — step-free layouts, grab-bar blocking behind the tile, sound separation between floors, and finishes that read as one continuous home rather than an annex.
full basement finishing
Full Basement Finishing
Open family rooms, playrooms, and flex space. Framing, insulation upgrades, drywall, flooring, layered lighting, and trim — turn-key from bare concrete to colour-matched baseboards, with the mechanical soffits planned rather than improvised.
basement home theatre
Home Theatres & Media Rooms
Decoupled walls and resilient channel for real acoustic isolation, pre-wired projector and 7.1 runs, tiered riser platforms, dimmable low-glare lighting, and HVAC zoning so the room stays comfortable through a three-hour film.
basement bathrooms kitchenettes
Basement Bathrooms & Kitchenettes
Below-grade plumbing done properly — slab cutting, ejector or macerator systems where gravity drainage isn't available, waterproof membrane behind every wet wall, and ventilation sized to code rather than to the cheapest fan on the shelf.
basement gym recreation room
Home Gyms, Offices & Wine Rooms
Purpose-built rooms that earn their square footage: impact flooring and reinforced assemblies for free weights, dedicated circuits and hardwired data for a real office, and insulated, climate-controlled cellars for wine.
basement waterproofing
Waterproofing & Moisture Control
Perimeter drainage assessment, dimpled membrane, interior drain tile, crack injection, sump and battery backup, and engineered subfloor panels. None of it is visible when we're done — and all of it decides whether the basement is still dry at year fifteen.
underpinning bench footings
Underpinning & Bench Footings
Lowering a basement floor to reach legal habitable height — 2.0 m clear, 1.95 m at beams. Sequenced pin-by-pin with a licensed structural engineer on every project, so your home stays safe, insurable, and financeable.
egress windows entrances
Egress Windows & Entrances
Saw-cutting concrete foundation walls for code-compliant egress openings and private suite entrances, including window wells, drainage tie-ins, exterior stairs, and the lintel work that keeps the wall above doing its job.

How Our Basement Renovation Services Work
divider

Every basement remodeling project follows the same proven four-step process — built to keep your renovation on schedule, on budget, and free of the surprises that make people dread renovating:

1.
Site Consultation
On-site assessment of moisture history, ceiling height, structure, and existing mechanical services. Free, no pressure, usually within 5 business days of your call.
2.
Design & Fixed Quote
Floor plans, 3D renderings where they help you decide, material selections, and a line-item quote you can hold us to. No vague allowances left open to interpretation.
3.
Permits & Build
We prepare drawings and pull every permit through your municipal building department. Then our crew builds — framing, mechanical, finishing — with one project manager accountable throughout.
4.
Inspection & Handover
Final municipal inspection, deep clean, walkthrough with a punch list we actually close out, and warranty paperwork in your hands. You move in. We follow up.
Why Basement Renovation in BC Requires a Different Approach

Homes across the Lower Mainland take on 1,100 mm to 1,900 mm of rain a year, and the soil holds it. Saturated ground presses moisture against foundation walls in every season, not just during a storm. Almost none of the failed basements we are called in to fix failed because of a flood — they failed because of decisions made during the original basement finishing.

Every Total Renovations basement development is designed around a moisture strategy before a single stud is cut. Our basement renovation experts address water at each layer of the assembly:

Included on Every Basement We Build
Exterior grading and perimeter drainage review — fix the source before sealing the symptom
Dimpled membrane on foundation walls to break capillary contact with concrete
Closed-cell spray foam or rigid foam insulation — never fibreglass against concrete
Engineered subfloor panels lifting finished floors off the cold slab
Moisture-resistant drywall in below-grade and bathroom zones
Mechanical ventilation sized to BC Building Code for the new occupancy
Radon mitigation where soil testing indicates elevated risk
Sump pump with battery backup for homes sitting near the local water table
Why This Matters for Your Basement Renovation

A basement that is finished but not moisture-managed follows a predictable timeline: musty within three winters, mould behind the drywall by year five, and a demolition bill that exceeds what the original basement remodeling cost in the first place.

We have inspected hundreds of failed basement renovations before quoting a remediation, and the pattern almost never varies — fibreglass batts pressed against concrete, no vapour strategy at all, laminate laid straight onto the slab. It photographs beautifully for about a year. Then the climate does what the climate does.

Our basement remodeling services typically land 8–12% above a budget quote. That entire difference sits in the moisture assembly: the part of the build you will never see, and the only reason your basement renovation still looks and smells new at year fifteen.

Permits & BC Building Code — What Every Basement Renovation Needs
Any basement renovation involving structural work, plumbing, electrical, or a secondary suite requires permits. Building without them creates insurance gaps, resale complications, and in the worst cases an order to remove the work. As licensed basement contractors we manage every application and inspection on your behalf. Here is what your basement remodeling services include:
Building Permit
Required for structural changes, new partition walls, ceiling-height alterations, and any work that changes how the basement is used or occupied. We prepare the drawings and carry the application through plan review.
Electrical Permit (Technical Safety BC)
New circuits, panel and service upgrades, kitchen and bathroom GFCI/AFCI protection, and separate suite metering or sub-panels where the design calls for them.
BC Energy Step Code & Section 9.36
Effective insulation values for below-grade walls, continuous air sealing, and the energy compliance path your municipality has adopted. We specify above minimum, because minimum performs like minimum.
Egress Window Requirements
Every basement bedroom needs a compliant escape opening — minimum 0.35 m² openable area with no dimension under 380 mm. We coordinate the concrete cutting, lintel, window well, and drainage tie-in.
Plumbing Permit
Needed for new bathrooms, kitchenettes, laundry, sump and ejector systems, and any new fixture connection below grade — including below-slab rough-in where gravity drainage is not available.
Gas Permit
New gas-fired appliances, dryer hookups, fireplace installations, and any modification to existing gas lines when a suite is added. Certified gas fitter, permitted and inspected.
Secondary Suite Bylaws
Minimum floor area, separate entrance, one-hour fire separation, sound separation, parking, and egress. Thresholds differ by municipality, so we check your specific zoning bylaw before quoting a suite.
Ceiling Height Minimum
2.0 m clear in habitable rooms and 1.95 m at beams and ductwork. We measure before quoting and only recommend underpinning when the numbers genuinely require it.
