Meet James Armstrong

Meet the Master Plumber Serving Dallas: James Armstrong

James Armstrong started in plumbing in Mesquite, TX in 1995 as an apprentice, then as a Journeyman, and since the early 2000s as a Texas Master Plumber. He runs James Armstrong Plumbing from our shop at 844 Dalworth Dr., Suite 10 in Mesquite. Same shop, same address, since 1995.

“Emergency plumbing calls are the calls where the customer is most vulnerable to being oversold. Something’s actively broken, water’s flowing, and every plumber who shows up knows the pressure to say yes. Our rule is the same at 2am as it is at 2pm: quote the honest fix, explain what you’re doing and why, and if a temporary shut-off gets the customer to morning without more damage, that’s what we quote. Emergency dispatch shouldn’t mean emergency pricing beyond the after-hours premium.”

FAQ

Frequently Asked Questions

Have questions? We’ve got answers. Can’t find what you’re looking for? Give us a call anytime.

Our friendly team is available 24/7 to help you.

Active flooding, sewage backup into the home, water heater tank leak with no hot water, gas smell in the home, burst supply lines in winter freezes, continuously overflowing toilets that cannot be shut off at the wall valve, and slab leaks with active water damage. Situations that can be isolated at a shut-off valve without causing damage usually save money by waiting until standard business hours.

Our shop is at 844 Dalworth Dr., Suite 10 in Mesquite. Emergency dispatch to East Dallas neighborhoods typically arrives within 25 to 40 minutes during business hours and 45 to 90 minutes overnight and on weekends. Response times to Southeast Dallas may be at the higher end of that range. Dispatcher gives an honest estimated arrival window when you call. No promises we cannot keep.

Yes, after-hours dispatch includes a premium above the standard business-hours rate for the same service. The premium typically adds 30 to 50 percent to the base flat rate. That premium is quoted up front before any work begins. If waiting until morning would safely save the customer money without adding damage risk, we say so honestly at the time of the call.

Shut off water at the affected fixture first. Every sink, toilet, water heater, and washing machine has a local shut-off valve. If the local shut-off does not hold, shut off the main water supply at the meter or utility closet. For gas smell, leave the home immediately and call Atmos Energy at 866-322-8667 from a safe distance. Do not use electrical switches, phones, or anything that could spark. For sewage backup, stop using water throughout the home to avoid adding to the backup.

Yes for most standard tank replacements when the failed unit is a common 40 to 50 gallon gas or electric size. Emergency water heater replacement includes the new unit, install labor, disposal of the failed unit, and any code-upgrade items. Tankless conversions are usually deferred to next-business-day dispatch because they typically require gas line evaluation and specialty venting that is not practical to complete overnight.

Ask three questions. Is water or sewage actively causing damage right now? Is essential utility (hot water, working toilets, drinkable water) completely lost? Is there a health or safety risk (gas, sewage in living areas, structural water damage)? Any yes answer warrants emergency dispatch. If all three are no and the problem is contained at a shut-off valve, waiting until standard business hours usually saves 30 to 50 percent on the call. When in doubt, call and describe the situation. We give an honest recommendation before dispatching.

Our friendly team is available 24/7 to help you.
