## What Is a Design-Build Basement Renovation?

A basement renovation turns the most underused level of your home into real, comfortable living space — a family room, a home office, a guest suite, or a code-compliant legal apartment. As a 

design-build renovation firm

[/ →](/)

, we handle the whole job under one roof: the moisture control, any structural work, the framing and systems, and the finishes, all on one fixed price.

A finished basement adds genuine living space and value to your home, but only when it is done right. The difference between a basement that lasts and one that fails is the work below the surface — the waterproofing, the drainage, and, where ceiling height is tight, the underpinning. We finish basements, increase ceiling height through underpinning or bench footing, and build legal apartments across Toronto.

Below-grade work is exactly where renovations tend to run over budget, because digging uncovers surprises. That is why our fixed-price approach is so valuable here. We scope the moisture control and structural work during pre-construction and price it precisely, so the budget holds from the first day to the last.

### What’s Included

A basement renovation with us covers design, permits where required, interior or exterior waterproofing, sump pumps and backwater valves, any underpinning or bench footing, framing, insulation, electrical and plumbing, finishes, and final clean-up.

## Common Basement Problems We Solve

### Wasted, Unfinished Space

An unfinished basement is often a third of your home doing nothing. We design it into usable living space tailored to your family — and, where the layout allows, into income or in-law space.

### Low Ceilings

Many older Toronto basements feel cramped because of low headroom. Underpinning and bench footing lower the floor to gain real ceiling height, transforming how the space feels.

### Moisture and Dampness

A damp basement cannot become living space until the water problem is solved. We address waterproofing, drainage, sump pumps, and backwater valves before any finishing work, so the finished room stays dry.

### Wanting a Legal Rental or In-Law Suite

A code-compliant legal suite needs proper egress, fire separation, ceiling height, and permits — details that, done wrong, make a suite illegal. We build legal secondary suites correctly the first time.

## Planning Your Basement Renovation

We begin with an honest assessment of moisture, ceiling height, and structure. From there we design the layout around your goals, scope the below-grade work, and lock in the fixed price. Because the unpredictable parts of a basement project are settled before construction starts, your renovation stays on budget and on schedule.

Got Questions?

## Basements Renovation FAQs

How much does a basement renovation cost in Toronto? expand\_more

Most basement renovations in Toronto start around $50,000, with the figure rising for underpinning, legal-suite conversions, and extensive waterproofing. Below-grade work is where many projects run over budget, which is why our fixed-price model is especially valuable here — we scope the moisture control and structural work before pricing, so the number holds.

How long does a basement renovation take? expand\_more

A straightforward basement finishing runs several weeks, while projects involving underpinning or a legal suite take longer because of the structural work and inspections. We reserve a dedicated crew for the entire build, keeping the schedule predictable.

Can you make my basement taller through underpinning? expand\_more

Yes. Underpinning and bench footing lower the basement floor to gain ceiling height, turning a cramped, low basement into proper living space. It is significant structural work, so we manage the engineering and permits and price it precisely before construction begins.

Can you build a legal basement apartment? expand\_more

Yes. We build code-compliant legal secondary suites with proper egress windows, fire separation, ceiling height, and the City of Toronto permits required. A legal suite can provide rental income or space for extended family.

How do you keep a finished basement dry? expand\_more

Moisture control comes first. Depending on your home, we install interior or exterior waterproofing, weeping tile, a sump pump, and a backwater valve before any finishing work begins. Scoping this up front is what protects your investment.

Do I need a permit for a basement renovation? expand\_more

Most basement projects that involve structural work, underpinning, new bedrooms, or a legal suite require a City of Toronto building permit. We prepare the drawings, submit the applications, and coordinate every inspection.

What is included in the fixed price? expand\_more

Our fixed price covers design, permits where required, waterproofing, any underpinning, framing, insulation, electrical and plumbing, finishes, and final clean-up. The below-grade work is scoped before the contract is signed, so there are no surprise costs.

Do you offer a warranty on basement renovations? expand\_more

Yes. As a licensed and insured general contractor, we stand behind our work and pledge a strict two-business-day response time on all warranty claims.
