You found three contractors. One has a 4.9. One has a 4.6. One has a perfect 5.0 with eleven reviews.
Most people pick the 4.9 and call it research. It is a coin flip in a nicer outfit.
Ottawa general contractors reviews are worth reading. Just not the way most homeowners read them. The score is the least useful thing on the page. Everything that matters is in the text, the dates, the replies, and the things nobody bothered to write down.
Ratings compress. One number takes fifty different experiences and flattens them into something that fits on a badge.
Two companies can both sit at 4.7 and be nothing alike.
The first has a hundred reviews. Mostly strong. A handful of clients annoyed about a schedule slip. The second has twelve reviews. Nine glowing, three describing a project that went badly wrong. Same number on the badge. Completely different risk to you.
Volume beats average. A 4.6 across ninety reviews is a company with a real history and normal human friction. A 5.0 across eleven is a sample too small to mean anything, and it might just mean they only ask the happy ones.
So start with the count and the date range. Then ignore the score for a while.
Contractors change. Crews turn over. Owners step back from the tools.
A company that was excellent in 2022 might have doubled in size, hired fast, and lost whatever made it good in the first place.
Sort by newest. Read everything from the past year. That is the company you would actually be hiring.
Watch the tone shift. If older reviews praise the owner by name and recent ones mention a project manager who never called back, the business grew and the experience changed with it. That is not automatically bad. It is a question to ask on the phone.
Watch for gaps too. Steady reviews for years and then eighteen months of silence usually means something. Slowed down, changed names, moved on. Ask.
Five star reviews are short and emotional. Great work. Highly recommend. Thanks so much.
One star reviews are the opposite. Furious, detailed, and sometimes about something the contractor never controlled in the first place.
The three and four star reviews are where the truth lives. These are people who were mostly satisfied and had no reason to exaggerate in either direction. They will tell you the tile work was excellent and the job ran three weeks long.
That is exactly what you need to know.
Read every three star review a company has. It takes ten minutes. It is the most valuable ten minutes of your whole search.
One bad review means nothing. Every contractor who has lasted in Ottawa has had a client nobody could satisfy.
Patterns mean everything.
Read fifteen or twenty and keep a tally in your head. Communication mentioned as a problem four separate times, by four unrelated people, across two years? That is not bad luck. That is the operating model. Same goes for cleanliness, deficiency follow-up, and schedule.
Positive patterns count just as much. Several clients independently mentioning that the crew swept up every day, or that the same lead carpenter was there start to finish. Nobody invents that.
Sort what you find into buckets as you go. Quality of work. Communication. Schedule. Budget accuracy. Cleanliness. Coming back after final payment. Most companies are strong in some and weak in others. Your job is deciding which weakness you can live with.
Fake reviews exist in every trade. They have a shape once you know what to look for.
Real reviews are specific and slightly messy. They mention the basement in Orleans. The eight week timeline. The plumber who came back on a Saturday to fix a leak.
Specificity is the strongest signal of authenticity there is.
Google is where everyone looks. It should not be the only place you look.
Cross-reference the same company across Google, HomeStars, the Better Business Bureau, and their own social accounts. Forty strong Google reviews and a very different picture somewhere else is worth a second look.
Social media is underrated for this. Look at the actual project photos. Is it the same six jobs recycled for three years, or a steady stream of new work. Do the comments come from people who sound like real clients in Kanata and Stittsville, or from accounts that are obviously not local.
Then search the company name next to words like complaint, lien, or review. Thirty seconds. Occasionally it saves you an enormous amount of money.
Nobody checks this. It might be the most predictive thing on the page.
Find a negative review. Read the owner's reply.
A good response is calm. It acknowledges the client's experience, states the company's side without heat, and offers to sort it out offline. It reads like an adult who has handled conflict before.
A bad response argues. It blames the client, drags up unrelated details about their payment history, or turns sarcastic.
That reply is a preview. If something goes wrong on your project, that is the tone you will be dealing with in your own kitchen.
Silence on every negative review is an answer too. It usually means nobody is watching, or nobody cares to.
Once reviews have cut your list down to two or three names, put them away. They cannot tell you the last mile.
Ask each finalist for two or three references from projects like yours, finished six to twelve months ago. Recent enough that people remember. Old enough that any problems have surfaced.
Then call and ask real questions.
That last one is the tell. People will say polite things about a job that was fine. They hesitate before recommending someone for a bigger project.
Then verify the paperwork yourself. Liability insurance. A WSIB clearance certificate you confirm through WSIB directly. Not something you take on faith because a review said the crew was nice.
Reviews get you to the shortlist. Phone calls and documents get you to the right hire.
Even a hundred honest reviews leave out the things that matter most to your project.
They will not tell you whether this company is right for your specific job. A contractor with glowing reviews for kitchen work may have built two basements ever. Reviews rarely separate the two, and the star average will not warn you.
They will not tell you what the company looks like right now. Reviews describe finished projects, which means they describe a company that existed six or twelve months ago. In between, a lead carpenter may have left. Three new hires may have arrived. The owner may be running twice the volume.
They will not tell you who is actually showing up at your house. Some companies sell the job and subcontract the entire build. That can work well. But the crew that earned those reviews may not be the crew in your driveway, and you should ask.
They will not tell you anything about financial health. A contractor who is stretched thin will start your job to get your deposit and then move the crew to whichever site is screaming loudest. No review captures that until it has already happened to someone.
And they will not tell you how the company handles a real dispute. Most reviews come from projects that went fine. The rare ones that went badly are the least reliable, because by then everyone involved is angry.
None of this makes reviews worthless. It just means they are the first filter, not the last word.
Here is the whole thing in order.
An afternoon of reading. A few phone calls. That is the whole cost, and it is the cheapest insurance available on a project this size.
Each place you read reviews has its own bias built in. Knowing the bias helps you weigh what you read.
Google has the most reviews and the widest reach. Anyone with an account can post, which is the strength and the weakness. The volume is real. So is the noise. Google reviews skew short and emotional in both directions, and they cover everything from a full home renovation to a phone call that never got returned.
Trade-specific platforms attract a different kind of review. People who go out of their way to write on a renovation-focused site are usually describing a substantial project, and the reviews tend to run longer and carry more detail. Smaller sample, higher information per review.
The Better Business Bureau is not really a review site. It is a complaint record. Almost nobody files there to say a job went well. Read it for whether formal complaints exist and how they were resolved, not for a balanced picture.
Social media comments are the weakest signal on their own but useful as a cross-check. What you are really looking at is the photo feed, not the comments.
Neighbourhood groups are underrated. A recommendation in a Barrhaven or Orleans community group comes from someone whose name is attached and who has to see their neighbours again. That accountability makes those recommendations worth more than an anonymous five stars.
Review counts measure how well a company asks, not only how well it builds.
Some contractors have a process. Final walkthrough, final payment, then a follow-up asking for a review with a direct link. Those companies accumulate reviews steadily.
Others never ask. They have been busy on referrals for twenty years, the owner is on site every day, and nobody in the office has ever thought about it. That contractor can be excellent and have eleven reviews.
So a thin review profile is a question, not a verdict. Ask them directly. How do most of your clients find you? A contractor who says most of our work comes from referrals and repeat clients, and who can then produce five references without hesitating, has answered it.
The reverse is also worth noticing. A company with a very large number of reviews and a very short history has been marketing hard. Not disqualifying. Just worth understanding, because heavy marketing spend has to come from somewhere and it usually comes out of the job.
Reviews are most useful when you convert them into specific things to raise on the phone.
If several reviews mention slow communication, ask this. Who will be my day to day contact, how often will I hear from them, and what is the expected turnaround if I send a question on a Tuesday afternoon?
If reviews mention schedule overruns, ask this. How many active projects will your crew be running while mine is open, and what happens to my timeline if one of them runs long?
If reviews mention deficiencies not getting fixed, ask this. Walk me through your deficiency process. How is the list created, who signs off, and how much of my final payment stays back until it is closed?
If reviews mention costs climbing, ask this. What was the last project where the final number moved significantly, why did it move, and what would you do differently?
If reviews mention mess, ask this. What is your standard for end of day cleanup, and who is responsible for it?
Every one of these is a fair question. A contractor who answers them plainly, without getting defensive, is telling you something the reviews could not.
By the time you have read forty reviews across three companies, everything blurs. Write it down as you go.
Make a column for each contractor and a row for each of these.
Score each one out of five based on what you actually read, and leave a blank where the reviews told you nothing. The blanks matter as much as the scores, because those are the things you have to find out by phone.
Two useful things come out of this. You stop relying on the impression left by whichever review you read last. And the pattern of blanks tells you exactly what to ask each finalist.
It takes twenty minutes. On a project this size, that is the best return available on your time.
Most contractor profiles carry project photos, and people scroll past them. That is a mistake, because photos are harder to fake than text.
Look at what is in the frame besides the finished room.
Check whether the photos are of real completed jobs or stock images. Stock photography is easy to spot once you look for it. Perfect styling, no wear, furniture nobody owns, lighting that could not exist in a normal house. Real project photos have a lamp in an odd spot and a slightly crooked cushion.
Look at the transitions and edges. Where the new floor meets the old. Where trim meets the wall. How the tile lines up at an inside corner. Anyone can photograph a nice kitchen. The corners are where the workmanship shows.
Look for photos of the same project at different stages. A company that posts framing, rough-ins, and the finished space is showing you the work, not just the result. It also suggests they were on site the whole time.
Check whether the photos look like Ottawa houses. Brick semis, side-splits, wartime bungalows, older homes with small original windows. A gallery full of enormous open-concept builds that look nothing like local housing stock may be borrowed.
Then look at the range. If every photo is a kitchen and you are hiring for a basement, you have learned something the star rating never told you.
Reviews, photos, references, and paperwork each answer a different question.
Reviews tell you how the company treats people over time. Photos tell you what the work looks like. References tell you what happened when something went wrong. Paperwork tells you whether you are protected if something goes badly wrong.
None of the four is sufficient alone. A company can have excellent reviews and no insurance. Beautiful photos and a terrible schedule record. Perfect paperwork and work nobody would want in their house.
Run all four before you sign anything. It costs you an afternoon and a few phone calls.
Then trust what you found. If three of the four are strong and one is genuinely worrying, that worry is real information, not something to talk yourself out of because you like the owner or because you are tired of looking.
The homeowners who end up with renovation horror stories are almost never the ones who did this work. They are the ones who found someone available, liked them on the phone, and signed.
There is no exact threshold, but a rating built on a handful of reviews is a weak signal. Look for a track record spread across several years rather than a burst of reviews in a single month. Consistency over time matters more than the raw count.
Not necessarily. Any contractor with a long history has had a job go sideways, because renovation involves weather, suppliers, subtrades, and human beings. A perfect score usually means a small sample or selective review collection. A strong rating with a few honest mixed reviews is often more reliable.
Use both. Google has the widest reach and the most reviews, while trade-specific platforms tend to attract clients writing about larger projects in more detail. Reading the same company across two or three sources beats trying to pick one to trust.
Read it carefully, read the company's reply, then check whether anything similar shows up elsewhere. A single outlier with a measured response from the owner is usually not a problem. Raise it directly during your call and listen to the explanation. How they explain it tells you more than the review did.
Yes, and you should. It is a fair question and a good contractor will answer it plainly. Watch for defensiveness or a story that keeps changing shape. Someone who says here is what happened and here is what we changed afterward is showing you they learn from problems.
