1. Magnolia Design & Build
4.8 (125 reviews)score 89/100
Composite score of 89.1 sits near the top of this list, built on a 4.8 rating across 125 reviews. Reviewers describe Joey and a stable named crew (Richard, Faraz, Pierre, Michelle, Giuseppe, Stacy) handling basement excavation, additions, and multi-room renovations while keeping quotes on budget. Weekend responsiveness and repeat clients back up the consistency.
- Owner personally answers calls on weekends
- Named crew shows up project after project
- Stays within quoted budget even on tricky sites
- Handles bedrock excavation and underpinning
Watch out: One project ran two weeks past schedule, though reviewers said the result justified the wait.
Services: detached garage construction, garage additions conversions, custom finishes heated garages
2. Capital Homes
4.9 (112 reviews)score 86/100
A 4.9 rating from 112 reviews backs a composite score of 85.6, with named project managers Conor, Ammar, and Moe cited again and again for transparent estimates and hands-on follow-up. Kitchen, bathroom, and multi-room work tends to land on budget, and the team keeps checking in months after the crew leaves.
- Named project managers stay involved start to finish
- Transparent, no-surprise cost estimates
- Follow-up support up to a year later
- Clean worksites and careful handling of existing fixtures
Watch out: A few projects have run longer than the initial estimate, sometimes due to supplier delays outside their control.
Services: detached garage construction, garage additions conversions
3. The Assembly Experts
4.7 (153 reviews)score 85/100
Three years of repeat business and 153 reviews at 4.7 stars give this composite score of 84.5 real weight. The team builds gazebos, pergolas, sheds, and solariums in hours rather than days, and reviewers note the work holds up season after season without loosening.
- Turns around builds fast, often same day
- Structures stay solid over multiple seasons
- Crew cleans up and invites inspection before leaving
- Quick to respond by email
Watch out: A small number of one-star reviews describe payment confusion and a slow response to a roofing panel failure.
Services: detached garage construction, garage additions conversions, custom finishes heated garages, garage permits design
4. Best Handy solution Inc
5 (24 reviews)score 84/100
All 24 reviews land at five stars, giving this composite score of 84.2 a near-perfect base, though the review count is smaller than the leaders on this list. Said and his team handle appliance installs, shed assembly, and gazebo builds like a 14x12 project finished in a single day, adjusting on the fly when parts run short.
- Perfect five-star record across every review
- Said responds quickly and arrives on schedule
- Completes large builds like a 14x12 gazebo in one day
- No extra charge for follow-up visits when parts are delayed
Watch out: With 24 reviews, there's less of a track record to draw on than some of the higher-volume names on this list.
Services: detached garage construction, carriage house laneway garage
5. Cooper Builds
5 (32 reviews)score 84/100
Every one of 32 reviews gives Calvin five stars, supporting a composite score of 83.5. Work spans bathrooms, kitchens, decks, fences, and custom woodwork, with reviewers pointing to clear quotes, on-time finishes, and daily dust control and cleanup.
- Detail-oriented craftsmanship on every job
- Clear, fair quotes upfront
- Finishes on schedule and on budget
- Handles both small emergency fixes and full renovations
Watch out: The review base is smaller than the top names here, so the sample is thinner even though every review is positive.
Services: detached garage construction, garage permits design
6. OakWood Designers & Builders
4.5 (105 reviews)score 83/100
A composite score of 82.6 rests on 105 reviews at 4.5 stars, with named staff Dan Lavigne and Mike Ortis repeatedly credited for patient design work and clear planning on custom homes and kitchen renovations. The firm runs design and build under one roof, from 3D renderings through final finishes.
- In-house design team with 3D rendering
- Named, experienced project managers
- Transparent, collaborative handling of cost surprises
- Thorough workmanship guarantee
Watch out: At least one reviewer noted site preparation costs ran higher than expected on a large custom build.
Services: detached garage construction, custom finishes heated garages
7. Ottawa Carleton Construction
5 (12 reviews)score 76/100
A perfect 5-star average holds up across 12 reviews, giving this composite score of 76.3, though the review count is on the low side for full confidence. Owner Frank Porcari's hands-on leadership and knowledge of Ottawa building codes come up repeatedly for custom homes and multi-unit projects delivered on schedule and budget.
- Owner Frank Porcari directly involved in every project
- In-house architecture and design team
- Consistent on-time, on-budget delivery
- Responsive follow-up after completion
Watch out: With only 12 reviews, this is one of the thinner track records on the list, worth weighing against the higher-volume names above.
Services: garage additions conversions, detached garage construction
8. Garage Living
5 (205 reviews)score 94/100
The highest composite score on this list at 94.1, backed by a 5.0 rating across 205 reviews.

- Named crew known by returning customers
- Diagnoses problems like slope or failed coatings before starting
- Finishes ahead of schedule with a spotless site
Services: detached garage construction, garage additions conversions, custom finishes heated garages, garage permits design
9. Ottawa General Contractors
4.4 (233 reviews)score 76/100
With 233 reviews at 4.4 stars, this is the highest review volume on the list, and the composite score of 75.5 reflects genuinely mixed sentiment behind that number. Named project managers Murad, George, Roger, and Adam earn praise for daily photo updates and coordinating multiple trades on large interior renovations, but a number of one-star reviews describe surprise invoices and an NDA required to receive compensation credits.
- Named project managers coordinate multiple trades
- Daily photo and portal updates during the build
- Often finishes on or ahead of schedule
- Warranty on completed work
Watch out: Multiple reviewers report unfinished work, surprise charges, and pressure to sign an NDA before receiving any compensation, so get contract terms locked down before signing.
Services: detached garage construction, garage additions conversions, custom finishes heated garages, garage permits design
10. Action Restoration foundation repair
4.9 (193 reviews)score 92/100
A composite score of 92.4 is backed by 193 reviews at 4.9 stars, among the strongest combinations on this list. Patrick and his crew handle foundation cracks, garage floor replacement, and water damage with the same transparent pricing whether the job takes hours or weeks, and reviewers say he flags hidden problems honestly during excavation instead of padding the bill.
- Owner Patrick personally responds to calls and site visits
- Same-day or next-day scheduling for most jobs
- Transparent pricing, communicates cost changes before proceeding
- Cleans and clears the site before leaving
Services: detached garage construction
11. Holland Homes & Renovations Inc.
5 (16 reviews)score 71/100
All 16 reviews rate five stars, giving a composite score of 70.7, though the recency sub-score is low, meaning much of that feedback is older. Owner Robert and project manager Scott get consistent credit for handling additions and renovations on century-old homes, coordinating trades, and keeping clients informed through surprises.
- Owner and project manager known by name across reviews
- Track record on century-old homes and structural surprises
- Transparent design process tied to budget
- On-time, on-budget delivery reported
Watch out: Reviews are both fewer and older than most names on this list, so recent performance is harder to confirm.
Services: carriage house laneway garage, detached garage construction, garage additions conversions
12. PR Builder
5 (25 reviews)score 69/100
A perfect five-star average across 25 reviews supports a composite score of 69.2, but the reviews themselves are light on detail about what specific garage or build work was done, and none are recent. It's a business worth a direct conversation before committing, given how little the review text reveals.
- Perfect five-star review record
- Licensed and insured
- Serves Nepean and the surrounding Ottawa area
Watch out: Review content doesn't specify which services customers were rating, and none of the 25 reviews are recent.
Services: detached garage construction
13. 613 Garage Door Repair
5 (46 reviews)score 87/100
A composite score of 87.4 comes from 46 reviews at 5.0 stars, with technician Nahum named repeatedly for showing up within hours and quoting prices that match the final invoice. Spring replacement, off-track repairs, and opener programming all get consistent praise, and repairs come with a written warranty.
- Same-day emergency response, often within hours
- Written warranty on every repair
- Transparent pricing with no upsell pressure
- Technician Nahum known by name for reliability
Services: detached garage construction, garage doors openers
14. Monaco Construction
4.1 (58 reviews)score 68/100
A composite score of 67.6 reflects a genuinely mixed record: 4.1 stars across 58 reviews, with solid craftsmanship on shorter jobs like decks and window wells but real trouble on longer projects. Communication and site cleanliness vary a lot depending on the job, and a few reviewers report unresolved issues after completion.
- Crew praised for solid craftsmanship on decks, kitchens, and bathrooms
- On-time delivery reported for shorter jobs
- Attentive to specific client requests
Watch out: Longer projects have drawn complaints about weeks of silence, an untidy site, and quality issues like cracked cement steps needing later repair.
Services: detached garage construction
15. Ram Overhead Doors Ottawa
4.5 (189 reviews)score 83/100
Serving Ottawa since 1984, Ram carries a composite score of 82.6 from 189 reviews at 4.5 stars, the kind of volume that comes with decades in business. Technicians Bryson, Jason, and Stefan get called out for same-day repairs and honest pricing, including a customer who returned after 20 years for a repeat job.
- Same-day or next-morning service
- Parts kept in stock for fast repairs
- Pricing consistently beats competitors, per reviewers
- Long-standing business, established since 1984
