Chimney Sweep Mississauga – Expert Chimney Repair

Just had the chimney swept after...well, way too long. The company was excellent to deal with, on time, efficient, and knowledgeable. I appreciated that they did not try to upsell me on anything and only gave me the information I needed and an honest assessment of when I will need their services again. In a world where contractors are constantly lying to pad their services, this company was a breath of fresh air! Highly recommend, and will be making them my regular fireplace and chimney crew.

I thought my chimney needed more cleaning so A1 sent someone back again to do a more thorough job! excellent business practice. Thank you!

Great service

Dillan never fails to help me keep up with the maintenance of my fireplaces keeping debris out and repairs up! if your a homeowner of even just want to use your own chimney I recommend using these guys for any concerns

A1 did a repair job for me today on my chimney. Hisham did a very good job. This company offer a very competitive and reasonable rate to fix my issue. Highly recommended.

Very professional, they did a great job!

The technician who arrived Jacob was extremely professional and explained so much. Very helpful. Great service. Highly recommend

I’ve engaged these folks numerous times to clean the chimney for my wood stove and been quite satisfied. This past time the technician pointed out that my chimney slab was deteriorated and showed me what he could see from the street. I asked him to get me a quote on a repair. After a bit of confusion, Owen the owner sent me a quote that I approved and we set a date for the repair. When Owen arrived I asked for some before and after photos and a check that squirrels hadn’t started a nest as a result of the deterioration. He discovered that the slab was falling to bits and carefully removed it so as not to have debris fall on the neighbour’s houses which are very close. He cemented a new slab, chimney tile and installed a more secure cap, as we previously had squirrels setting up a nest as a result of wire mesh failing on a previous cap. The level of workmanship was excellent as is evident in the photos. I wouldn’t hesitate to recommend Owen and his crew and will have them back in the future.

We have had A-1 clean our chimney several times in our 100+ year old house and the service was always extremely pleasant and professional. When we mentioned a strong fireplace smell after rains, Jacob (who did the cleaning) gave us several pieces of good advice, and said the office would follow up. Within a few days we had a more detailed lengthy call with Owen who described all possible causes and cures to the odour issue. They were both very helpful and I would recommend A-1 highly.

Exceptional service. They fit us in at the end of the day and solved the issue that two other firms could not. After the problem was resolved, Owen took a look at our chimney cap and reported no further work was required. Fast, clean and thorough. Impressive. Thank you !!

I can't thank Owen enough for his help. I was in a stressful situation involving a B-tag and a questionable liner install from another company. Owen took the time, despite being fully booked, to review photos, give an honest assessment, and walk me through what needed to be done. His guidance was incredibly clear, professional, and spot on. He didn’t charge a thing for the advice, yet it made all the difference in getting the job done properly and confidently. It’s rare to find people in trades who are this responsive, kind, and genuinely helpful. Highly recommend A1 Quality Chimney and will absolutely call them first for any future work.

I use A1 quality chimney Cleaning every year. They are conscientious, kind, tidy, thorough and have great customer service. They back all of their work and are incredibly knowledgeable and thorough. I strongly recommend you try them! Jacob was terrific.

The guys at A1 chimney are fantastic, highly knowledgable about the fireplace maintenance, chimney code, and potential repairs you may need. Definitely recommend.

We had an amazing experience with Owen from A-1 Fireplace! From the moment he arrived, he was friendly, professional, and clearly very knowledgeable. He took the time to thoroughly assess our chimney, gave us great advice, and explained everything in a way that was easy to understand. It really felt like he cared about making sure we knew exactly what was going on and what steps to take next. His clear instructions and honest recommendations gave us total peace of mind. Outstanding service—we wouldn’t hesitate to call A-1 Fireplace again or recommend Owen to anyone needing chimney or fireplace help!

Great on the phone - Talked through my set up, asked great questions and gave options. Was willing to offer a more temporary solution but we agreed to do it once and do it right, no pressure. Great on site - My house is very old, soooo much character. Along with that comes difficulty, old bones are sometimes brittle. The repair and replacement of my chimney flute took under 4 hours, and the work looks great (currently and from photos shown while the work was being done). Great price - Honestly came in at the best price from other companies I had reached out to. I was considering doing this work myself, but I am glad I reached out!

Jacob did an excellent job cleaning our chimney. He was knowledgeable, professional, and friendly, explaining the process clearly and offering helpful next steps for setting up a regular cleaning schedule. We’ll definitely use their service again. Highly recommend!

Outstanding Service with Integrity – Highly Recommend A1 Quality Chimney This review is long overdue, as I wanted to see the full results of A1’s work—and I am beyond impressed. Kelly and Owen went above and beyond in installing a chimney liner for me. When unexpected condensation issues arose, Kelly carefully assessed the situation, explored multiple solutions, and remained committed until the problem was fully resolved. A1 operates with honesty, integrity, and a true commitment to excellence—qualities that are rare today. Their dedication to finding lasting solutions rather than quick fixes sets them apart. Kelly was especially patient, responsive, and genuinely invested in ensuring the best outcome. His professionalism and customer care were truly outstanding. I wholeheartedly trust and highly recommend A1. If you're looking for a company that stands by its work and values integrity, A1 is the gold standard. Thank you, Kelly and Owen—you are truly the best! After a frustrating experience with a previous contractor, I am so relieved that my chimney issues are finally resolved. A1’s expertise and dedication made all the difference.

Jacob from A1 showed up on time to fix our damper and clean the chimney, which he did quickly with no mess. He was very friendly, had all of the necessary equipment and gave me some advice on how to avoid future issues. I will use this company again.

Just had our chimney/fireplace cleaned and inspected for the first time in our home. The technician showed up right on time, was very knowledgeable, kind and super efficient. Will definitely be calling to set up our next clean! Thanks A1! And thank you Jacob!

We had a very good experience with A1 Quality Chimney. Our buyers didn't know what they wanted, so we needed a permit.We ordered an inspection to keep us calm for closing day. Blair Morris even offered extra work with no charge, and Kelly was really polite and professional. I'm really happy with this company.

Technician Jason did a fireplace inspection and cleaning today -- a professional, competent job and now I have peace of mind! Thank you

I had an outstanding experience with A1 Quality Chimney. Ours was a challenging job given the age of the house and the height and location of the chimney. The service people were professional, knowledgeable and went out of their way to give me advice and make sure the service was perfect. They were both very neat and paid close attention to details as though it was their own home. I can’t speak highly enough about this company and I look forward to seeing that back at my house after 40 burns or annually, whichever occurs first.

Completely satisfied with their service. Easy to make an appointment, they also confirmed the appointment the day prior. Jacob showed up at the agreed time and was pleasant and efficient, also very helpful in answering my questions. This is the second time I have used this company and both times I had the same positive experience.

Overall great experience with A1. Their technician, Jacob, visited our house and he was kind and personable throughout, giving me great advice about how to properly ready the fireplace for a fire and about the cleaning routine. Additionally, he was honest about the fireplace being relatively clean (we had not used it since buying the house), and told me to give them a call again after having around 40 fires. All of this and no charge or fee! A1 has definitely earned my business for the next time I need my fireplace looked at. Thanks Jacob!

This is my second time using A1, and I’m thrilled with the experience. Their technician, Jacob, is fantastic. He arrived promptly and performed a thorough job. He also provided valuable tips on checking the airflow in the chimney, which will surely help me avoid unnecessary service calls. A1 is a great company that genuinely cares about its customers.

Jacob was very efficient cleaning my chimney today. He also gave me some great advice about how to maintain. Very reasonable price too. Would definitely recommend.

I just had Jacob at my house and he told me our chimney actually didn't need cleaning yet. He explained only after about 30 more fires we would need a cleaning, if we were okay with that. I was not expecting this, especially because he took the time to come out to our house and I wasn't paid a service fee. I have used this company in the past for repair and cleaning and I am always pleased with their service. Thank you!

Jacob demonstrates excellent customer service. He is an extremely knowledgeable professional. He took the time to answer all of our questions. Highly recommend.

I had a great experience getting my fireplace cleaned and looked at today for the first time. Jacob was really patient, kind and answered all my questions and made me feel at ease about everything. He was thorough in explaining everything I had to do. Would definitely recommend to anyone who needs their fireplace looked after.

I had an excellent chimney cleaning with A1 Quality Chimney today. Jacob arrived at the time stated, was friendly, professional, and cleaned up after he finished cleaning my chimney. He also gave very helpful advice. I will continue to use A1 and highly recommend them!

Always professional and prompt. Hisham is great! Very neat and efficient with his work!

Great service at a very reasonable price. Owen was excellent in cleaning the chimney and providing advice. I can highly recommend this company.

Amazing service. The service person they sent worked clean and fast. I don’t need as much work as they thought so he only charged for what I needed. Amazing to find a service as reliable and honest as A1. Would recommend them to anyone who requires work or cleaning of their chimney!!

We have had several good encounters with A1 servicing our chimney over the years. With the most recent flood, we noticed some water leaking into our furnace flue. Kelley came very quickly to assess our chimney and suggested some caulking and other repair work that was needed. The work was completed this morning in a thorough manner. The worker just needed a reminder to clean up after himself, though some mess was still left in the backyard.

Friendly sales and on site team that explained everything before and after the chimney rebuild. I appreciated the refresher on how to safely use my fireplace after the cleaning. Thanks!
