Best chimney services businesses in Ontario

★★★★★5 (166 reviews)score 93/100

Universal Roofs built its reputation on finding what other contractors missed, from failed seals to parapet tracking, backed by 166 reviews at a perfect 5.0 average. Reviewers repeatedly describe being sent elsewhere first and only getting a real answer once Oltion's crew inspected the job, which matters for chimney flashing and roof-junction leaks that are easy to misdiagnose. The team documents each stage and names crew members (Olti, Pat, Nick) consistently across jobs.

• Tracks down root causes on leaks other contractors couldn't solve
• Named crew (Olti, Pat, Nick) shows up on schedule and communicates clearly
• Honest second opinions before recommending replacement work
• Clean, tidy job sites with attention to finishing details

★★★★★5 (163 reviews)score 93/100

BNS Roofing's 163 reviews at a 5.0 average consistently mention one thing: they inspect before they sell, and they will tell you a repair is enough when a full replacement isn't needed. Silvi and Keno handle consultations personally, often same-day or within a week, which is useful for a chimney leak that needs a quick, honest read. East York and North York customers specifically call them out as the only contractor who didn't try to upsell them.

• Owner-led consultations (Keno, Silvi) with fast turnaround
• Won't push a full replacement when a repair will do
• On-time crews that clean up and document work with photos
• Reasonable pricing for the quality delivered, per reviewers

★★★★★4.9 (247 reviews)score 93/100

Luso Roofing carries the largest review base on this list, 247 reviews at 4.9, with a pattern of recommending repair over replacement when that's genuinely the cheaper, correct fix. Nuno's team sends photos before starting work and operates seven days a week, which counts for time-sensitive chimney and flashing leaks. Repairs come with a guarantee, and reviewers say the team returns if an issue resurfaces.

• Recommends repair over costly replacement when appropriate
• Photo documentation sent before work begins
• Guarantees repairs and returns if problems persist
• Available 7 days a week across the GTA

★★★★★5 (103 reviews)score 91/100

Outstanding roofing pairs a perfect 5.0 across 103 reviews with a habit of solving problems on the spot rather than scheduling a return visit. Peter, Drieu, and Mike are named across jobs for flashing, vent, and fascia work adjacent to chimney leak points, with before-and-after photos that reviewers say helped with insurance claims. Every review mentions fair pricing and a refusal to push unnecessary upsells.

• Insurance claim support with before-and-after photo documentation
• Fast response and same-day problem-solving on site
• Honest, no-pressure pricing with clear explanations
• Thorough cleanup after every job

★★★★★4.9 (42 reviews)score 86/100

Jimmy's crew arrives within 30 minutes to an hour on emergency calls and typically finishes the same day, which matters when a chimney or roof leak is actively letting water in. The 4.9 average holds across 42 reviews, a smaller but still solid sample, and reviewers in Scarborough and across the GTA describe fair pricing and a willingness to fix problems beyond the original scope, including critter and animal-proofing work around chimney openings.

• Emergency arrival within 30 minutes to an hour
• Fixes issues beyond the original scope without extra pressure
• Animal-proofing and critter damage experience
• Fair, transparent pricing on emergency calls

★★★★★4.9 (50 reviews)score 85/100

Trusted Roofers Toronto holds a 4.9 average across 50 reviews, with owner Jaime known for responding to quote requests within seconds. Beyond roofing, the team handles aluminum, eavestroughs, siding, and waterproofing, useful if chimney flashing repair overlaps with broader exterior work, and most jobs close out in a single day including ice dam and winter leak fixes. Photo documentation for insurance claims comes up repeatedly in reviews.

• Jaime responds to quote requests within seconds
• Full-service exterior contractor beyond roofing alone
• Ice dam and winter leak specialists
• Photo documentation prepared for insurance submission

Watch out: One reviewer among the 50 had to finish part of a job themselves after a communication lapse, though this appears isolated.

★★★★★4.9 (48 reviews)score 82/100

The Roof Whisperer holds a 4.9 average across 48 reviews with a smaller footprint than the top names on this list, but reviewers describe consistently prompt arrival and clear, plain-language explanations of what's needed. The focus on skylight fixes alongside leak diagnostics and shingle work makes them a fit for chimney-adjacent leak troubleshooting, and no recurring complaints show up in the feedback.

• Prompt on-site arrival and efficient completion
• Skilled diagnosis of leaks and skylight issues
• Clear, plain explanations of the work needed
• Thorough cleanup and respectful of the property

★★★★★4.7 (58 reviews)score 82/100

Henry's crew at TORONTO HD.ROOFING holds a 4.7 average across 58 reviews, slightly lower than the names above it but still built on a base of competent, honest craftsmanship. Reviewers say the team finds root causes other contractors miss on flat roofs and finishes on time and on budget, with follow-up calls after the job. It's worth weighing against the smaller number of mixed comments noted below.

• Finds root causes other contractors miss on flat roofs
• Finishes on time and on budget
• Honest, transparent pricing
• Follows up with clients after the job

Watch out: A couple of reviewers noted it was harder to reach Henry after the job wrapped up, and one flagged a communication issue from years back.

★★★★☆4.2 (10 reviews)score 63/100

Northern Masonry is the only business here with chimney work named directly in reviews, alongside roofing and waterproofing, and roughly 80% of its 10 reviews are five-star. That said, this is a small sample and recent one-star reviews describe a blocked chimney left unresolved after work, along with missing documentation and warranties, so treat the composite score here as lower confidence than the rest of this list.

• Quality materials and workmanship when jobs go smoothly, per reviewers
• Handles multiple trades (roofing, waterproofing, chimney) on one property
• Responsive to emergency calls
• Attention to detail noted in positive reviews

Watch out: Recent reviews cite a blocked chimney left unresolved, missing invoices or warranties, high-pressure payment demands, and unaddressed property damage, so get everything in writing before hiring.
