Renovating in Ottawa means wading through hundreds of names on Houzz, HomeStars, Yelp, and the BBB. To narrow the field, we looked at general contractors and design-build firms that are currently operating and serving the Ottawa area, cross-checking their own websites against public review platforms for area served, specialty, and verifiable ratings. This is not a ranked top-to-bottom list, just ten worth knowing about.
1. OakWood Designers & Builders
Area: Ottawa-wide · Specialty: custom homes, major renovations and additions · Rating: 4.4 on Birdeye (61 reviews) · Since: 1956
OakWood is a family-owned design-build firm now in its fourth generation, with more than 10,700 completed projects on its books according to its own site. It has picked up BBB Torch and Consumer Choice awards for renovation and design over the years. It suits homeowners planning a large-scale project, like a full addition or custom build, who want architectural design and construction handled under one roof.
2. Ottawa General Contractors (OGC)
Area: Ottawa, Barrhaven, Kanata, Nepean, Orleans, Almonte and surrounding communities · Specialty: kitchens, bathrooms, basements, additions, custom and mini homes · Rating: 4.3 on Birdeye (279 reviews)
OGC runs what it calls a three-step design, planning, and construction process, and holds NKBA membership, Tarion warranty coverage, a Best of Houzz badge, and GOHBA membership. It has also been featured on CTV and HGTV. With hundreds of reviews behind it, it suits homeowners who want a larger, more established outfit for a full-service renovation.
3. Select Urban General Contractors Inc.
Area: Nepean, Barrhaven, Kanata, Stittsville, Carp, Vars, Vanier, Orleans, Russell, Manotick, Alta Vista, Westboro · Specialty: kitchen, bathroom and basement renovations, home additions, coach houses · Rating: 4.96 on ProvenExpert (27 reviews), A+ with the BBB
Select Urban is BBB accredited with an A+ rating and offers in-house design and 3D planning. Reviewers have specifically pointed to teams that clean up tidily at the end of each work day, and to additions that blend well with the original structure. It's a solid pick for homeowners who want to see a 3D plan before committing to a renovation.
4. On Point Renovations
Area: Ottawa, Orleans, Kanata, Stittsville, Nepean, Manotick, Kemptville, Gloucester, Barrhaven · Specialty: bathroom, kitchen and basement renovations, flooring, tile and decks · Since: 2020
On Point was founded by two Ottawa-raised construction professionals with a combined 20-plus years of experience before starting the company. It carries a StarScore in the high 80s on HomeStars. It's a good fit for mid-size renovation jobs in the west and south end of the city.
5. Kanata Renovations
Area: Kanata and surrounding Ottawa communities · Specialty: kitchens, bathrooms, decks, additions, basement finishing, stonework · Rating: A+ with the BBB
Based in Kanata, this company says it has over 30 years of experience, and at least one client testimonial on its own site describes working with the company for more than a decade. Reviews across platforms are mixed but generally positive on professionalism and workmanship. Homeowners in Kanata and the west end who want a locally rooted, long-running company may want to start here.
6. Altior Construction
Area: Ottawa region · Specialty: residential and commercial construction and renovation, eco-conscious building · Rating: 5.0 on Yelp (6 reviews)
Altior describes itself as a full-service general contractor handling new construction, design-build, and remodeling for both residential and commercial clients. A Yelp reviewer specifically praised a bathroom remodel for being efficient and friendly. Its review base is small, but what's there is positive, and it may suit homeowners interested in sustainable or eco-conscious building upgrades.
7. Monaco Construction
Area: Ottawa, Orleans, Gloucester, Kanata, Barrhaven, Stittsville · Specialty: kitchen and bathroom remodeling, basement finishing, foundation repair · Rating: 3.7 stars (6 reviews), A+ with the BBB
Monaco has been BBB accredited since 2023 and has been operating since 1985 according to its own business listings. Customer feedback found in our research was mixed, with some praising the quality of the work and others flagging responsiveness and pricing transparency, so it's worth getting a clear, written quote up front. It's a longtime name for homeowners who also need foundation-related repair work alongside a standard renovation.
8. Cayman Construction & Renovations Inc.
Area: Barrhaven, Kanata, Orleans, Nepean, Gloucester, Stittsville, Rockcliffe Park · Specialty: kitchen, bathroom and basement renovations, general contracting, additions · Rating: 4.2 to 5.0 depending on platform (Houzz)
Cayman says it has more than 25 years of experience and covers everything from drywall and flooring to full additions. Reviews we found were largely positive, including repeat customers who came back for multiple projects and named owner Darrell specifically, though at least one negative review flagged a plumbing issue on one job. As with any contractor, it's worth asking for references on a project similar in scope to yours.
9. Arnet Construction
Area: Nepean, Stittsville, Kanata, Barrhaven, Orleans, Rockland, Bayshore · Specialty: basement renovations, separate dwelling unit (SDU) conversions
Arnet is a newer company, in business since 2021, with an in-house team of designers, drafters, engineers and permit specialists. It's a narrower specialist than most names on this list, focused specifically on basements and secondary dwelling unit conversions, which makes it a good option for homeowners specifically chasing rental-unit or in-law-suite potential rather than a whole-house renovation.
10. Vez Renos (Vezina Home Renovations)
Specialty: bathroom renovations
We could not find an independent business website for Vez Renos, so this entry links to its HomeStars profile instead. Reviews there describe owner Denis handling full bathroom tear-downs, walk-in shower installs, tiling, vanities and plumbing, with customers noting he is punctual, communicative and tidy. It's a smaller, specialist operation best suited to a single bathroom project rather than a whole-home renovation.
