Checking references and reviews — what to ask and what to look for
This article is for educational purposes only and is not a substitute for professional advice. Local codes, regulations, and best practices vary by region.
A contractor can provide stellar references they’ve coached. Online reviews can be faked or exaggerated. But references and reviews are still valuable signals if you know how to read them.
The trick is asking the right questions and looking for patterns, not isolated positive or negative statements.
Contractor-Provided References
A contractor will give you references they trust. These are almost certainly satisfied customers. You won’t get a reference from someone they built a deck for that leaked.
But a reference who was satisfied is still information. Ask specific questions beyond “Would you hire them again?”
Questions to Ask References
“Was the work completed on time?” This tells you whether the contractor respects timelines.
“Was the work completed on budget, or did costs exceed the bid?” If every reference says costs ran over, that’s a pattern. If some jobs came in on budget, the contractor can manage.
“Were there problems during the project? How did the contractor handle them?” Nobody’s perfect. How they respond to problems matters more than whether problems occur.
“Would you hire them again?” A yes is good. A hesitant yes is interesting. A no is the answer you need.
“Any regrets or things you’d change about hiring them?” This opens the door for nuanced feedback. Some people won’t volunteer complaints unless asked.
“Can I drive by and see the work?” If the reference says yes enthusiastically, that’s a good sign. If they hesitate, the work might not look great.
Listen to how references talk about the contractor. Enthusiastic comments are different from “Yeah, he was fine.” Tone matters.
What to Look For in Patterns
One negative reference doesn’t mean much. Everyone has a dissatisfied customer. Three negative references is a pattern.
References complaining about the same issue (“He’s always behind schedule,” “He never showed up when promised”) indicate a real problem.
References praising the contractor for the same thing (“He communicated constantly,” “He explained everything”) indicate a strength.
References with specific examples (kitchen remodel, bathroom, deck) are more valuable than generic praise.
Online Reviews
Online reviews are easily manipulated. A contractor with forty five-star reviews might have asked every satisfied customer to post. One-star reviews might come from an unreasonable homeowner or a competitor’s sabotage.
The reviews worth reading are the three- and four-star reviews with specific details. “Great work, professional, finished on time” is generic. “The tiles are perfectly aligned, grout work is excellent, finished a week early” is specific and credible.
One-star reviews with vague complaints (“Never again!”) or generic criticism (“Overpriced”) are less useful than one-star reviews with specific issues (“Promised he’d match our existing tile grout color, used a completely different shade, and refused to fix it”).
A contractor with a few three-star reviews (acknowledging minor flaws) seems more trustworthy than all five-stars (likely curated).
Look at review dates. Recent reviews are more relevant than five-year-old ones. A contractor’s practice might have changed.
What Reviews Don’t Tell You
Reviews don’t tell you pricing strategy. A review might say “expensive” or “great deal” but that’s subjective.
Reviews don’t tell you whether costs stayed on budget. They might say the work was good but not address whether the job cost $10,000 or $15,000.
Reviews don’t tell you long-term durability. A review from six months ago about a roof can’t confirm the roof lasts.
Red Flags in References and Reviews
A contractor who refuses to provide references or offers only friends and family (not previous clients) is hiding something.
All references being friends or relatives rather than customers is suspicious.
Consistently negative comments about communication (not returning calls, not explaining work) are concerning. Communication matters long-term.
Patterns of budget overruns or timeline delays suggest a real problem.
Complaints about the contractor vanishing once the check cleared suggest someone unreliable.
How to Use This Information
References and reviews are signals, not facts. Use them to identify patterns and red flags.
A contractor with solid references from actual recent projects, mixed but thoughtful online reviews, and no patterns of serious complaints is probably fine.
A contractor with enthusiastic references, a pattern of budget and timeline reliability, and communication compliments is probably excellent.
A contractor with vague references, universally bad reviews, or patterns of complaints isn’t worth hiring.
Trust your judgment. If references are glowing but something about the contractor feels off, trust that feeling. If references are mixed but the contractor impressed you, feel confident hiring them.
