Most South Philly chimneys were built for coal. The rowhomes from Passyunk to Point Breeze went up between the 1850s and 1920s, brick stacks packed tight against each other along narrow streets, and the flues inside them were sized for a coal stove. Over the decades those same flues were switched to oil and then to gas, and each switch dropped a new appliance into a liner that was never built for it. That history is why we keep finding the two faults specific to this neighborhood: hairline cracks in the original clay tile, and smoke chambers left oversized for the gas units now venting through them. Either one can let combustion gases drift back into a tight party-wall home, so the work has to start with seeing what is actually inside the stack.
That is the job a sweep does here. We clear out the flue, then run an interior video scan the full length of it to read the liner, the smoke chamber, and the damper for yourself, and we put a written report and a CO draft test in your hands on every visit. Same-day slots open most weeks for the times a detector goes off and you need someone on the roof before sundown.
More than 400 Americans die from unintentional carbon monoxide poisoning every year, according to the CDC's carbon monoxide poisoning information, and more than 100,000 land in the emergency room. A cracked clay liner, a blocked flue, or a back-drafting furnace is one of the most preventable causes. That is why every Franklin Chimney technician in South Philly is CSIA-certified, why the video scan and the CO draft test run together rather than as add-ons, and why we write the report in plain language you can act on instead of filing away.
Every service is CSIA-certified, fully insured, and locked to the price we quote.

Very happy with the work Franklin did at my house. Came out and gave an estimate and had work done same day. The crew cleaned, capped, pointed three chimneys and added a very stubborn flue connected to the boiler.
Selling my house, and I wanted the chimney inspected They found an issue, and they were able to fix it super fast! Good people!
Franklin Chimney did a wonderful job fixing my chimney and putting in a stainless-steel liner and cap on top of my chimney. They came out quickly for an estimate and did the work in the same week. They were very professional and explained everything they would be doing before the job started. I highly recommend them to anyone looking for honest, reliable, and high-quality service. Thank you for making this such a great experience!
I had an emergency situation that needed immediate help. Franklin chimney came the next morning and estimated the job for me. The estimate was totally in line with the research other companies that I had done and Franklin came out the next day to do the job. I am so relieved to have this major problem in my house corrected. They were great communicators, on time, clean, fair, professional, and did a great job I could not recommend them more.

We needed a level 2 chimney inspection on a quick timeline for our HOA. Franklin Chimney came out in less than 48 hours. Booking was very easy and price was significantly better than competitors. Our technician Madi was very efficient and made sure we had the report we needed.
Tony was honest, excellent, and professional in my home. Strongly recommend
A great experience. The workmanship was exceptional and the pricing was way under other estimates. No overselling and high quality finish work. Count me very happy.
Thanks you for Franklin chimney for a wonderful job, they did the chimney liner professional and clean job
I called Franklin Chimney when I noticed flies coming out of my wood burning stove. Maty was here within an hour. He sent a drone up on my roof and discovered a few holes in the mesh that was easy access for birds or squirrels to enter. He sent 2 guys out the next day. They were friendly, efficient and fast. They removed 4 birds and a squirrel. Put a new cap on chimney and sealed it off with mesh. They were done in about 2 hours. I highly recommend Franklin Chimney....thank you for doing a great job!
The federal guidance on chimney maintenance is plain. Debris in the flue can cause carbon monoxide to build up inside the home, and the CDC's recommendation is to have your chimney checked or cleaned every year. Full reference: CDC carbon monoxide poisoning information.
