- Clear communication and regular project updates
- In-house permit and inspection handling
- High-quality, detail-focused workmanship

2. Vulcan Hats Constructions - Home Renovation Brampton
5 (51 reviews)score 88/100

3. Great Choice Construction
4.8 (51 reviews)score 83/100
Great Choice brings over 20 years of experience and a licensed, insured, WSIB-covered crew, with a 4.8 rating from 51 reviews leaning heavily positive for fast, polished concrete and patio work. One detailed complaint about basement drainage and mismatched windows keeps this from the very top, but it's an outlier against a broadly strong track record.
- Polished concrete and finish work
- Quick project turnaround
- Licensed, insured, and WSIB-covered crews
- Professional, punctual teams
Watch out: One reviewer reported improperly leveled drainage and windows that didn't match what was ordered.
Services: detached garage construction, custom finishes heated garages, garage permits design, garage additions conversions
4. Dreamland Constructions
4.5 (26 reviews)score 76/100
Kamaljeet's team earns a 4.5 rating from 26 reviews for on-time delivery and navigating complex city permit approvals on garden suite and basement projects, with staged payment plans that reviewers appreciate. A handful of one-star reviews describe slower responses and unresolved defects after handover, so this fits best for buyers who confirm warranty terms up front.
- Owner-led navigation of complex city permits
- On-time project delivery
- Flexible staged payment plans
- Clear communication during the build
Watch out: Some reviewers describe slow follow-up and reluctance to fix defects like leaking showers after the project wrapped.
Services: detached garage construction, garage additions conversions
5. Home Services at The Home Depot
5 (2 reviews)score 65/100
This Home Depot Home Services location carries a 5.0 rating, but from just 2 reviews, so there isn't much of a track record specific to garage additions or conversions. It's licensed and insured with WSIB certification and $1M liability coverage, worth a look mainly for smaller-scope work.
- Knowledgeable, friendly staff
- Licensed and insured with WSIB certification
Watch out: Only two reviews exist, and neither clearly documents garage-specific work, so treat this as a low-confidence pick.
Services: detached garage construction, garage additions conversions
6. Fair Trade Builders | Basement, Kitchen & Bathroom Renovations
4.4 (7 reviews)score 61/100
Fair Trade Builders gets praise from four reviewers for responsive, fairly priced, on-schedule work, holding a 4.4 rating overall. That's weighed against one detailed one-star account of months-long delays, incomplete framing, and a failed city inspection, so this pick suits buyers willing to stay closely involved and check references first.
- Responsive to client priorities
- Fair, honest pricing
Watch out: A detailed complaint describes major delays, incomplete work, damaged fixtures, and a failed city inspection on one job.
Services: custom finishes heated garages, detached garage construction, garage additions conversions
7. Home Services at The Home Depot
2.3 (3 reviews)score 53/100
This Home Depot Home Services location carries a 2.3 rating from just 3 reviews, with two describing poor coordination and unresponsiveness to urgent requests. It's included because garage doors sit within their listed service menu, but the review record so far doesn't support it for a full conversion project.
- One reviewer praised a staff member's product knowledge
- Licensed and insured
Watch out: Multiple reviewers describe unresponsive service and communication problems, with negative sentiment outweighing the positive.
Services: detached garage construction, garage additions conversions
8. Home Services at The Home Depot
score 26/100
This Home Depot Home Services location lists garage door and opener installation among its services and carries WSIB certification with $1M liability coverage, but has zero reviews to draw on, which is why it sits at the bottom of this list. Consider it only after checking in directly on current garage-conversion capacity.
- Licensed and insured contractor
- WSIB certified with $1M liability coverage
- Multi-service provider covering garage doors, HVAC, plumbing, and electrical
Watch out: No customer reviews are available yet to verify real-world quality or reliability.
Services: detached garage construction, garage additions conversions
