My encounters with TerraFirma have been great so far. During an initial "inspection"/quote for a few potential projects, they mentioned how their company had been born out of a desire to provide exceptional customer service where other companies in the field were not, and I feel it really shows. The information I was provided was well-explained and never felt like a sales pitch - simply information presented to allow me to make the decisions I needed to. It also came from someone who seemed like they had hands-on experience in the work, not just a representative in a uniform. I also received no "pestering" beyond this appointment, which I appreciated - I get that follow-up is a way that business try to hook new work, but the company I'd gotten a quote from two years prior still calls and emails me to this day, which gets annoying. That same company had also quoted me a price quite a bit higher for the same work, so despite someone commenting to me that TerraFirma was "the pricier option," their offer was a fantastic deal to me.
I went ahead with scheduling the first project, crawlspace drainage and sump pump installation. The work was done well and cleanly, and communication throughout and after was great. I definitely plan to contact them again when I'm ready to tackle some higher-cost projects, and feel I don't need to bother with quotes from anyone else to know I'll be getting great work for a competitive price.
