Marvin and his team showed up and were very thorough and helpful to identify the issues and the repairs needed. Will be calling him again for all my fireplace / chimney needs.

I recently had my gas fireplace serviced by 8SIX8 Chimney Service. My experience started off a little rocky — the initial invoice had an error, and the fireplace wasn't fully cleaned during the first visit. However, the company handled the situation very well.
The technician returned promptly, was very personable, professional, and genuinely apologetic. He completed a full and proper cleaning, repainted the inside of the fireplace, refreshed it with new black decorative rocks, and even removed a screen that had a visual defect. The result looks like an upgrade — the fireplace looks significantly better and feels brand-new again.
I’m giving 4 stars because of the initial mix-ups with the billing and incomplete service, but the follow-up was excellent and left me very satisfied with the final result. I appreciate the technician’s care, attitude, and attention to detail. I would use this company again.

Marvin was extremely responsive and professional. He took the time to talk through specific fireplace issues we had and didn't try to sell us anything we didn't need. Very courteous and helpful!
