Frequently Asked Questions

Filter by topic, then tap a question. A real person answers every call, 24/7.

Do you offer 24/7 emergency service?

Yes. Our dispatch office is staffed Monday through Saturday, 7am to 7pm, and a licensed technician is always on-call 24/7 for emergencies. Every call is answered by a real person — no answering machines, no overseas call centers. Whether it's a burst pipe at 2am or a no-cool AC on a Sunday, someone picks up.

What areas do you serve?

We cover 20+ cities across North Louisiana — Lincoln, Ouachita, Caddo, and Bossier parishes. From Ruston out to Monroe, West Monroe, Shreveport, and Bossier City, we dispatch crews with same-day availability in most cities. Not sure whether we serve your ZIP code? Call (318) 319-0220 and we'll confirm.

How fast is your emergency response time?

For true emergencies — burst pipes, sewer backups, gas leaks, water heater or AC failures — we target on-site response within 60 to 90 minutes across Ruston and surrounding areas. Response for outlying service areas can run 2 to 3 hours depending on crew location. We communicate ETAs in real time.

How does your pricing work — and do you offer financing?

We quote flat-rate pricing upfront, before any work begins — no hourly surprises. Payment is collected on completion, never before, with an itemized invoice. We accept all major credit cards, debit, and ACH/check, and offer financing through our partners for larger projects like water heaters, repipes, and HVAC installs.

Do you offer warranties on your work?

Yes. All labor comes with a 1-year workmanship warranty standard, and parts carry the manufacturer's warranty (typically 5 to 10 years depending on the product). Major installs like water heaters, repipes, and HVAC systems carry extended warranties — often up to 10 years on parts and 2 years on labor.

Are your technicians licensed and background-checked?

Every technician on our roster is W-2, background-checked, and Louisiana-licensed — never a subcontractor. We're a veteran-owned, family-operated company that's held North Louisiana's trust for 30 years, licensed, bonded, and fully insured across plumbing, heating, and cooling.
