Black Lab Fab is Seth's Florence metal fabrication shop, and its website says he started in the iron working trade in 1999 before the business grew into a small family operation. The site lists custom handrails, gates, fences, stairs and CNC plasma table work. Google shows 5 from 7 ratings; Angi and HomeAdvisor each show 5.0 from 3. The reviews, from 2024 and 2025, cover homes and businesses. In an April 2025 Google review, a homeowner said Seth installed handrails for the front steps, indoor stairs and back deck of their newly built home. Another April 2025 customer said he quickly fabricated a custom piece for a project underway. A January 2025 business customer said Seth has repaired the company's equipment and got them back in running order quickly. A June 2025 reviewer said he finished the job ahead of schedule, and a September 2024 Angi customer said the work came in on time and on budget.
High quality and timely work. Seth was communicative, friendly and completed the job ahead of schedule. I highly recommend him!
Friendly professional High quality beautiful work
I highly recommend Black Lab Fab for all of your welding needs! Seth installed beautiful handrails for my front steps, indoor stairs, and back deck of my newly built home. I absolutely love how they turned out and I get so many compliments on them. His skills are truly unmatched!
Seth is great to work with! He quickly and easily helped us fabricate a custom piece for a project we have underway, and we are looking forward to working with him again as soon as we have a need. He's professional, low-key, experienced, skilled and totally enjoyable to work with. We'd highly recommend working with him for your next project that requires custom metal work.
Absolutely One of the best welders !! Did a wonderful job! Structurally sound work ! Willl be using Seth again. !
