Meet James Armstrong
Meet the Master Plumber Serving Mesquite: James Armstrong
James Armstrong has been a Mesquite Master Plumber since 1995. What started as helping neighbors with leaky faucets turned into a career, and eventually a family business, built on one simple rule: treat people right, do the job with integrity, and stand behind your work. Today James and his crew serve businesses and homeowners across Mesquite, Garland, Rowlett, Dallas, Plano, and Richardson, with most calls reached within 25 minutes of the Mesquite headquarters at 844 Dalworth Dr.
“A plumbing problem at a business is a different kind of urgent. Every hour that drain is backed up or that gas line is shut off, the owner is losing money and maybe sending customers home. So when I take a commercial call I move fast, I tell them straight what it will take, and I do it to code the first time, because a failed inspection or a callback is downtime they cannot afford. I have been doing this in Mesquite since 1995. I know the buildings, I know the inspectors, and I know what it costs a business to be closed for a day. That is what we are really protecting.”
