I have to be honest....they get 2 stars just for the professionalism of their workers. But the management of my repair job would embarrass any organization. The job was supposed to take 2-3 days...it took 3 whole months, with multiple visits that I had to be home for, all to re-adjust and repair a miscalculation done by the company owner who did the site survey...somehow he didn't realize after his inspections that my chimney pipe was not straight! The fact that he somehow missed this simple offset caused multiple delays, additions to the work, recalculations, waiting for parts, and readjusting work that had already been done. And after all that inconvenience, there was no offer by the company to make things right...only complaining about how much more money THEY had to spend to correct their mistake. Chimney "Scientists"? Hardly! read more

And the photos from the roof (so cool)& inside give me confidence my chimney, is in a sad state no longer . T read more

We had an outstanding experience with this company. At every level they were very professional, friendly and helpful. I would not hesitate to use them again! read more

The guys know what they are doing. Came and verified major issues, was honest and shown the results clearly. Recommended

we've had issues with out fire place smelling like smoke permeating throughout our downstairs for years now. Tried having the outside chimney repointed and thoroughly cleaned out even though we really don't use it that often. They came out in November and were very thorough and seemed very professional and extremely knowledgeable. They recommended sealant on the outside brick and additional capping and I accepted their proposal along with an inside chimney cleaning. I have to say the dampness is gone and I have not smelled the musty and smoke smell at all this winter. I am VERY happy with the work they did and would not hesitate to call them again. I initially thought the price was a little high but for the fact they fixed the problem it was of excellent value and well worth it. read more

Sadly, our experience with Chimney Scientist was disappointing from beginning to end. Over the course of 10 weeks, with multiple calls to a manager and two technician visits, we were continually assured that our Hearthstone wood-burning stove could be serviced. We paid $165 for the initial inspection in August and were told service would follow. Only after weeks of waiting were we informed that they could not service our 20-year-old stove -- something that would have been very helpful to know upfront before scheduling, paying, and waiting nearly two plus months. When I asked to speak with the president to share our experience, I was told he was not available and would not discuss the matter. While I was refunded the inspection fee, we are now back where we started, two months later, having to find another company on our own. A very frustrating and unnecessary waste of time. read more

great company and great job on my old chimney. can't wait to have fires this winter!

Fireplace Maintenance: On 2/13/26 a technician performed a 3 hour? maintenance and inspection service. When he was finished the fireplace was working but he said that there was too much gas going into the pilot light, it was dangerous and he could not leave the pilot light on but I could turn it back on after he left. He said he could probably not replace a part and I needed a new fireplace to the tune of $17K. I got a second opinion. After a 1 hour inspection and maintenance check by the second company (another cost of course) it was determined that I needed a part that cost $53 (nothing to do with the pilot light) and that I was never in any danger. Seniors, Beware! read more

Trust - that should be the one word the epitomizes Chimney Scientists. You can trust them in the quality of their assessment and their work!

Great work and great communication! Brandon was friendly and professional. Love this company!

My experience with Chimney Scientists started with a call from Chantal who was great! She was excited as I was that someone had cancelled an appointment for later that week. She sent Joe, who took the time to do a complete check, explained what the issue was so I could understand-he made me feel so comfortable! Gary and Jose were on time, calmed my fears, installed my new chimney, turned my boiler back on and cleaned up. It took less time than I thought it would, and they were both super friendly! So happy - thank you everyone at Chimney Scientists!!! read more

John was very helpful and informative. Total professionals, They helped diagnose and troubles my issue . read more

I needed to service our gas fireplaces, called this company, was visited by Marc who explained that the units were ductless and couldn't be serviced, as too old and not been looked at for years. He was very professional and very pleasant, advised to consider an electric fireplace and did not charge us for his visit. I was thoroughly satisfied and recommend his company highly read more

Was recommended Chimney Scientists by a friend and very happy with the decision to use them. They did a full analysis of the chimney both inside and out and brought me in so I could understand what was going on. Also able to break the main job of getting my 90 year chimney ready to be in full use into two big parts. Very happy again. read more

Pedro and his colleagues were superb! The were highly knowledgeable, very efficient and friendly. My 1896 home has two fireplaces they deep cleaned them both, the library one I kept wood burning, The living room one needed significant repairs and I had it converted to gas logs. Wow what a transformation! Thank you Chimney Scientists. I'd highly recommend them for any fireplace work you may need done! Best, Olin read more

After many years I had the chimney cleaned again. Got a call from the owner himself after service was complete. Stand up company! Reasonable pricing and we're back to burning in the wood fireplace. read more

As a new homeowner there is so much to learn and figure out about things you are completely clueless about. That is where the Chimney Scientists come in. From all we knew, we had a fireplace that was deemed not useable. The seller of our home set up an appointment for us with the Chimney Scientists and even though it was scheduled for about a month out, we kept it and we are so happy that we did. We hit the chimney scientist Jack pot when Zach came to our house for our initial appointment. We were blown away by his genuine kindness and care as a human and his wealth of knowledge about all things chimney and fireplace related was out of this world. And the best thing about Zach was that he took the time to thoroughly and thoughtfully educated us and explain all our potential options. We appreciated the time he took as his knowledge really helped us do the research we needed to decide how we'd like to proceed with our future fireplace needs. Zach is a HUGE assets to Chimney Scientists and we are so grateful to have him on our future fireplace project. read more

They were amazing- so professional and so complete-- their assessment with all of the photos and file and explanations sent; payment options; and their team! Every single person that worked on the team was so considerate, professional and worked the entire time to make my project come full circle. I am happy to share their info with my friends and family and will definitely consider them as my go-to. Reined my chimneys, installed gas fireplace in an older Philadephia home. Wonderful! read more

Joe and his team were incredibly responsive and friendly from the get go. They made the extra effort to fit me in a timely manner in their busy schedule. When Joe came out to do the job to inspect/clean our Chimney he was just as professional. He took extra time to make sure he got everything done right, clean up any debris and go over all my questions. In addition, he was on time and charged a fair price. So I would highly recommend them for your chimney needs. read more

Joe was great and the booking process was fantastic. The 2 stars is that they said they would give me three different quotes but I only received one, for thermocrete, the highest priced option. I feel like they forgot about me???? Also, after scoping my chimney they never cleaned the junk that fell etc during the inspection???? There was a pile of junk left in my fireplace. Looks like I will be calling another company.... read more

Joe and Antonio were amazing!! I am extremely satisfied with the work they did and the whole process of working with the staff. From the initial phone call to the cleaning I couldn't be happier. They were professional, friendly and respectful. I highly recommend They Chimney Scientist. And I will be using them again each year for maintenance. read more

I first booked an appointment on their website and never got a reply. After 10 days i called and they said it must have gotten lost in their shuffle, so we manually booked an appointment. When the day finally came (today) over a month had passed. The cleaner arrived and within 60 seconds was upselling me from a $179 sweeping to a $1200 chemical cleaning and based on the age of the house (25 years) i would need to spend $3500-$4500 more to have the chimney re-grouted. He hadn't seen anything in the chimney yet. I felt like this was a total hard-sell or a bait and switch tactic. Needless to say, i asked him to leave and will find someone else to do the job. I recommend staying away! read more

Very satisfied with service.Friendly and prompt.Spent lots of time explaining everything to me.

Chimney Scientists' owner, Joe and his entire team are true professionals. The cleaning and repair were done with precision and care. Joe had to order a special brush to get ours done thoroughly, and he was totally transparent and didn't add any "up charge." He also came out personally to ensure the work was done to the highest of standards. My husband and I have had a lot of work done on our home, and many of the businesses have been good--but Chimney Scientists are in a league by themselves. We strongly recommend Joe and his team if you need maintenance or work on your chimney. read more

Amazing service! Easy to schedule. Prompt and communicative. Super professional and knowledgeable. In addition to a chimney clean, they helped me eradicate the birds nesting in my dryer. Replaced the dryer vent cover. And, gave me great advice on next steps on fixing the washer/dryer unit. I'll use these guys EVERY year ... HIGHLY recommend!!! read more

We have recently moved to the area and found a house rather quickly. We were time crunched to get an inspection done during the busiest season of the year and somehow, the Chimney Scientist got us scheduled and got the report back to us within hours. Chantelle was amazing and was very transparent about the price, timeline and report expectations. Thank you helping us out with our first home purchase! read more

I had googled this company since I did not have any other resources. Am I glad I found the Chimney Scientist!! I booked my appointment with Chantel who is INCREDIBLE and was very professional, sweet, and accommodating. Lucky for me, there was an immediate opening! Joe & Dylan arrived within minutes of my hour window starting and from what felt like seconds, had laid tarp down and were ready to do their job. I've owed my home for 19 years and never had my chimney swept: always meant to get it done but never did until now. Joe was extremely thorough describing what the job entailed and the function of the machine and how it extracts the "soot" from the fireplace. He also recommended the best wood to use and where to get it from. The job was completed within minutes and the cost, well it is VERY REASONABLE and AFFORDABLE. While Dylan is on the quiet side, he did a PHENOMINAL and METICULOUS job. I was shocked how clean everything was and what great detail and attention was given to my home. Joe & Dylan rocked it! They are the best workers I've ever had come into my home and are full of in depth knowledge. So glad I came upon The Chimney Scientist and will be using them for all my chimney sweeps. Trust me, I'm a picky 100% Italian girl and it takes a lot to make me happy and these guys went above and beyond that! read more

Joe un-bricked and cleaned out our chimney. He was very tenacious in figuring out the quirks of our 120-year old chimney and communicating with the fireplace insert company so that our fireplace would be installed smoothly. He was friendly and responsive - great customer service with reasonable prices. I highly recommend this service. read more

Pedro and Joe just came to my manayunk home and inspected my gas boiler chimney and my woodburning stove chimney. 5 stars because they took time to explain everything, were very knowledgable and most importantly very honest. read more

I had these guys come out and clean out my wood burning stove and fireplace in the fall. They came on time and we're very friendly when they made their way in. A full inspection and then did a very thorough cleaning of the stove and chimney. After the cleaning, the tech explained everything he did and items that would be coming up in the future that should probably be taken care of. The chimney scientist is a great company to work with and is very trustworthy. I did a lot of research looking for a company and this one checked off all the boxes. I would recommend them to everyone. read more

I was very impressed by the receptionist Chantelle and the inspector Joe. Both of them were very patient and very friendly.

From start to finish, everything was A+. I had researched several other companies, but Chimney Scientist stood out with their professionalism and customer service. From the get-go, scheduling with Chantelle was a breeze and made me feel confident I had made the right decision. After receiving a confirmation the day before, Joe was right on time and super friendly and knowledgable. I just needed a chimney cleaning, and he was done within an hour. I have never seen my fireplace look that good. He also gave me some great tips about maintenance and types of wood to use for my particular chimney. 10/10 will be calling these guys again. read more

It was very easy to schedule an appointment to have my fireplace evaluated. Unfortunately, our fireplace issues were outside of the scope of work that this company does, but Joe was extremely helpful while explaining the work that would need to be done to our chimney. He was honest and thorough and clearly explained the current issues that we have and what our options will be moving forward In purchasing a new pre-fab fireplace. I will gladly recommend this company to others. read more

Working with this company was such a breeze. To start, Chantelle is one of the nicest people to work with; very courteous and responsive in scheduling the work. Joe and his team then took over and completed the necessary work in an expedited manner; thoroughly communicating to me along the way. I would not hesitate to contact for more work in the future. A+ read more

I'm extremely pleased with the cleaning I had done by The Chimney Scientist. They were very friendly and thorough. They also worked with me on scheduling a time that was convenient for me. Lastly, their prices were great. Another service I contacted wanted between $250-$400 for a cleaning. TCS charged $159. read more

Called at least a half dozen contractors to have our chimney cleaned. Most never returned the initial phone call. Isaac, the owner answered the phone and gave us a price for cleaning up front which was very reasonable. Turns out we only had a partial liner. Isaac gave us a very reasonable price to install a new liner but there was no pressure to use him. Isaac is very professional, knowledgable and it was a pleasure to work with him. I had to leave during the insttation for a short time with NO worries. Completely trustworthy. Would highly recommend. read more
