When to Repair Your Garage
Floor vs. When to Replace It

Not every damaged garage floor needs to be replaced and not every damaged garage floor can be saved.

Here’s how we think about it when we assess a job on-site:

Signs Your Garage Floor Can Be Repaired

✅ Surface cracks that haven’t penetrated the full slab depth
✅ Spalling or scaling affecting the top layer only
✅ Minor pitting from road salt or de-icers
✅ One isolated crack near the garage door lip
✅ Concrete still structurally sound underneath visible damage

→ See our Garage Floor Repair page for repair options

Signs Your Garage Floor Needs Replacing

Cracks running full depth through the slab
Multiple interconnected cracks across the entire floor
Significant heaving or sinking — floor is no longer level
Concrete was originally poured too thin (under 4 inches)
Rebar exposed and corroding throughout the slab
Repair costs approaching replacement costs
Floor has been repaired multiple times and keeps failing

We give you an honest answer on-site, we don’t push replacement when repair will do the job,

and we don’t patch floors that are past saving. Book a free assessment →

How We Replace a Garage Floor in Toronto

A garage floor replacement is a bigger job than a repair but we make it as smooth and disruption-free as possible.

Here’s exactly what happens from start to finish:

Free On-Site Assessment

We inspect the existing slab, check thickness, assess drainage, look for underlying subgrade issues, and give you an honest recommendation and written quote.

Old Concrete Removal

We break up and haul away the existing slab completely. Proper disposal included. We also address any subgrade issues — soft spots, drainage problems, or unstable base material — before pouring new concrete.

Subgrade Preparation

Proper base preparation is what separates a garage floor that lasts 30 years from one that cracks again in 5. We grade, compact, and prepare the base correctly before any concrete is poured.

New Concrete Pour

We pour a minimum 6-inch reinforced concrete slab using proper mix ratios for Toronto’s freeze-thaw climate. Rebar is embedded correctly, not laid on top, for structural integrity.

Finish & Coating Options

Once cured, we can leave your floor with a standard smooth finish, or upgrade to a polished concrete or epoxy floor coating for a showroom-quality result that’s easy to clean and protects the slab long-term.

Garage Floor Finish Options, From Basic to Showroom

A new concrete slab is just the foundation. Many Toronto homeowners use a garage floor replacement as

the perfect opportunity to upgrade their finish at the same time.

Here are your options:

Standard Smooth Finish

The classic garage floor finish, smooth surface,, practical and durable. A clean smooth finish on a properly poured slab looks sharp and lasts decades with basic sealing every few years. Most economical option.

Best for: Practical garages, budget-conscious projects

Epoxy Floor Coating Toronto

Our most popular garage floor upgrade. Applied over the new cured slab, epoxy flooring creates a seamless, high-gloss surface that resists oil, salt, moisture, and stains. Available in dozens of colours with decorative flake options. Turns your garage into a showroom.

Most popular combination

Polished Concrete Finish

A mechanically ground and polished concrete surface — sleek, minimal, and extremely durable. Polished concrete reflects light beautifully, requires zero coating maintenance, and is the premium choice for high-end garage or workshop spaces.

Best for: Premium finishes, workshops, studios

What Toronto Homeowners Say About Our
Garage Floor Work

Garage Floor Replacement in North York

“We had a problem with our garage floor where it was cracked by the lip. Hubert came out to inspect the floor and gave me two options. The first was to just repair the lip and this would have been the less expensive option. The more expensive option was to replace the entire floor. When asking for his professional opinion, Hubert said it was my choice, but in his experience a cracked lip also meant there would be issues with the rest of the floor. I decided that we would replace the entire floor and I am glad I did. The problem when the garage floor was initially installed was that the concrete was poured over the rebar instead of the rebar being embedded in the concrete. I’m glad I listened to the professional as this would have been a headache in the future. The guys worked hard and clean up was good. Thanks again Hubert!”

Garage Floor Replacement in Toronto

“I couldn’t be happier with my new garage floor. The crews were great. They were professional, skilled and friendly. My 70 year old garage floor was a broken dusty wreck. TCR gave me a solid quote and after removing the old floor, they meticulously prepped and poured the new floor. It looked amazing, only to be made more amazing with the epoxy sealer. It’s now the favourite room of my house!“

Mathew | Toronto

Garage Floor Replacement in Scarborough

“I am so happy with the work done by Toronto Concrete Repair I felt compelled to write this review. I first met Hubert in 2022 when he appraised a job to refinish my back porch. They did such an amazing job that when it came to do a complete garage floor three years later I thought of Hubert and Toronto Concrete Repair first.
And again he did not disappoint. He assigned Nick and his crew to redo my whole garage floor. They came on time every day. Did the job meticulously with care and cleaned up after they left.
Nick also gave me tips on how to maintain my floor. It is so refreshing in this day to have someone do what is quoted and expected of them. I have no hesitation recommending Toronto Concrete Repair.
Hubert, Nick and his crew were amazing !!!!
Thanks guys- I love my new garage floor“

Garage Floor Replacement Toronto — Frequently Asked Questions

Got questions? We've got answers!

How much does it cost to replace a garage floor in Toronto?

Garage floor replacement in Toronto typically costs $15–$20 per square foot for a standard concrete slab with smooth finish, and $20–$25 per square foot when combined with an epoxy floor coating. A typical single-car garage starts around $3,500. Factors like garage size, subgrade condition, and chosen finish affect the final price. We provide free written estimates so you know the cost before any work begins — contact us to book yours.

How long does a garage floor replacement take?

The demolition and pour typically take 1–2 days. The new concrete then needs to cure for a minimum of 14 days before normal vehicle traffic, and 28 days before applying an epoxy coating. We’ll walk you through the full timeline during your estimate so you can plan accordingly.

Should I repair or replace my garage floor?

Repair is the right choice when damage is surface-level, localized, or hasn’t penetrated the full depth of the slab. Replacement is recommended when cracks run full depth, the floor is heaving or sinking, the concrete was poorly installed originally, or the slab is too thin to support a lasting repair. See our full repair vs. replace guide above or book a free on-site assessment — we’ll tell you honestly which option makes sense for your floor.

How thick should a replacement garage floor be?

A standard residential garage floor should be a minimum of 6 inches thick for vehicle use, with 6–8 inches recommended for heavier loads or commercial use. One of the most common reasons we replace garage floors is that the original slab was poured at only 2–3 inches — far too thin for Toronto’s freeze-thaw climate and vehicle weight.

Can I add a drain when replacing my garage floor?

Yes — a full garage floor replacement is the ideal time to add a floor drain if you don’t already have one. We can incorporate a central drain or trench drain into the new slab design. This is especially popular in Toronto where road salt and snowmelt create significant water management issues in garages.

Do you add epoxy to the new garage floor?

Yes — we offer epoxy floor coatings as an add-on to any garage floor replacement. Many homeowners combine replacement and epoxy into one project since the concrete is already being poured fresh. The epoxy goes on after the slab has cured fully (typically 28 days), and dramatically extends the floor’s lifespan while making it look incredible.
