We had a complete chimney restoration and wood burning insert installed by Chimney Sweeps of America. This was the most expensive home projects we've ever done so I had lots of questions and concerns and the entire team at CSofA was amazing. They came out multiple times before our install to discuss all our options and make sure the unit we were buying would meet our expectations. On install day they were on time and were very courteous, professional and did great work. Also - they are CSIA certified and follow NFPA standards. (not all chimney sweeps in town are, do your research!!!) We are so pleased! Thank you so much CSofA!
