Overview
What commercial work we handle — and why dedicated matters
Commercial plumbing isn't just residential plumbing in a bigger building. Restaurants have grease traps and specialized kitchen sink configurations that need jetting on a schedule. Apartment buildings have shared mains where one clog affects 20 tenants and needs to be solved in an hour, not a day. HOAs have party-wall plumbing and shared water/sewer systems with specific repair procedures. Office buildings have restroom codes, ADA requirements, and tenant improvement projects where the plumbing has to be flexible enough to survive next year's floor plan change. Retail fitouts need fast, well-documented work that passes city inspection on the first try.
Mark Johnson & Sons runs a dedicated commercial crew with the equipment and experience to handle all of it. Separate commercial emergency line, separate trucks with commercial jetters, cameras rated for 4"+ mains, larger capacity equipment for apartment and office work. We maintain active service contracts with restaurants, apartment buildings, HOAs, property management companies, and retail property owners across North Louisiana.
Who we work with
- Restaurants and food service — grease trap cleaning, kitchen sink jetting, hand sink installs, mop sink repair, ice machine lines, and emergency backup response in the middle of a dinner rush

- Property management companies — portfolio-level service agreements across multiple buildings
- HOAs and condo associations — shared systems, common area plumbing, capital project planning
- Office buildings — tenant improvement plumbing, restroom remodels, emergency response, preventive maintenance
- Retail — fitouts, new store opens, lease-end closures, emergency backup response
- Medical and dental offices — specialized plumbing including vacuum systems, amalgam separators, water quality
- Schools and churches — large-capacity fixtures, ADA compliance, aging infrastructure
Services we offer commercial clients
Emergency response — dedicated commercial 24/7 line with 60-90 minute dispatch target across North Louisiana. Sewage backups, burst pipes, grease line failures — the kind of things that shut a business down until fixed.
Scheduled maintenance — quarterly, semi-annual, or annual jetting and service contracts for restaurants, apartments, and HOA shared systems. Usually 20-40% cheaper than à-la-carte pricing and prevents the emergency calls.
Grease trap cleaning and hydro jetting — required by most North Louisiana municipalities on a schedule. We handle the pumping, documentation, and city reporting requirements.
Backflow testing and repair — annual testing required on most commercial properties per Louisiana state regulations. We're certified testers and handle the paperwork.
Fixture install and repair — commercial-grade toilets, urinals, sinks, water heaters (tank and tankless), drinking fountains, mop sinks, and specialty fixtures.
Pipe repair and replacement — aging commercial mains, repipe projects, and drain line replacement with minimal business disruption.
Tenant improvement work — remodel plumbing, new buildout rough-in, code upgrades, and coordination with GCs.
Permits and inspections — North Louisiana cities require permits on commercial plumbing work. We handle pulling permits, scheduling inspections, and documenting everything for property records.
Why dedicated commercial matters
Commercial plumbing problems have commercial consequences. A clogged restaurant drain line during lunch rush is thousands of dollars in lost revenue. A failed water heater in an apartment building is a tenant complaint escalating to legal exposure. A frozen pipe in an empty office over winter break is a six-figure insurance claim. These aren't residential-urgency problems — they're business-critical.
Our commercial crew is trained to respond accordingly. Fast dispatch, clear documentation, insurance-compliant paperwork, and coordination with facility managers and property managers so the right decision-maker is always in the loop. We don't run commercial work through our residential queue — it has its own dispatch, its own crew, and its own response metrics.
What Mark Johnson & Sons does differently
Separate commercial dispatch line, separate commercial crew, separate service agreements. 24/7 emergency response across North Louisiana. Certified backflow testers, grease trap pumpers with city-compliance reporting, and licensed gas technicians. Volume pricing for multi-unit and portfolio clients. Master Service Agreements available with agreed-upon hourly rates, flat-rate repair pricing, and SLA-level response commitments.

The Process
How a Commercial Service Call Runs

On the truck
Professional tools, parts, and diagnostics — every call.
Commercial dispatch
Dedicated commercial line, not the residential queue. Dispatch asks for the property type, situation, urgency, and decision-maker contact. For emergencies, the commercial crew is rolling within minutes.
On-site assessment
Commercial tech arrives with appropriate equipment — commercial jetter, larger camera rig, commercial parts. Assessment includes system scope, property impact, and options.
Scope and quote
Written scope and flat-rate or time-and-materials quote (depending on service contract), sent to the property manager or owner for approval. Emergency work may proceed with verbal approval and written follow-up.
Repair or service
Commercial emergencies prioritize getting the business back open — often a bridge repair first, then scheduled full repair at a low-impact time. Scheduled maintenance (jetting, grease trap) runs on your timeline.
Documentation and follow-up
Written work order with photos, code compliance documentation (grease trap manifests, backflow test reports), invoice sent to your billing contact, and follow-up scheduling if maintenance is needed. Everything insurance and audit-friendly.
Pricing
How We Price Commercial Plumbing
Commercial pricing depends on property type, service scope, and whether you carry a service contract. Contract pricing lands meaningfully below à-la-carte, and everything is quoted before work begins.
Flat rate, quoted before we start
You get the full price for the job up front — not an hourly meter you watch climb. You approve it before a tool comes out of the truck.
The quote is the price
It doesn't move once work begins. If something unexpected turns up behind a wall or under a slab, we stop and talk it through with you before going further.

Service savings agreements start at $189 a year and take 15% off all plumbing, heating, and cooling repairs, with priority scheduling on every call. The Premium Service Savings Agreement Plan adds same-day service and drops after-hours charges entirely.

FAQ
Commercial FAQs
Do you have a separate commercial service line?
Yes. Commercial dispatch runs separately from our residential queue — commercial emergencies get immediate priority and our dedicated commercial crew is typically rolling within minutes. Separate phone line, separate trucks, separate parts inventory for commercial equipment.
What kinds of commercial properties do you serve?
Restaurants, apartment buildings, condos, HOAs, office buildings, retail, medical and dental offices, schools, churches, auto shops, and light industrial. We cover North Louisiana including Ruston, Monroe, and West Monroe. Portfolio clients with multiple buildings are handled under Master Service Agreements.
How much does commercial hydro jetting cost?
Commercial jetting is priced by pipe size, length, and severity — a small 2-3" branch line sits at the light end, a 4-6" main at the heavy end. Scheduled maintenance jetting on a 3, 6, or 12-month contract lands meaningfully below à-la-carte pricing.
Do you offer service contracts for restaurants and apartments?
Yes. Service contracts are the smart financial call for any commercial property with recurring needs — restaurants need quarterly or semi-annual grease line jetting, apartment buildings need annual main line jetting and preventive maintenance. Contract pricing is typically 20-40% below à-la-carte plus priority dispatch for emergencies.
Can you handle tenant improvement plumbing?
Yes. We handle new buildout plumbing rough-in, fixture installs, code upgrades, and permit coordination for office, retail, and restaurant TI projects. Pricing depends on scope, layout, and permit requirements, and we quote the full plumbing scope flat-rate before the job books.
Do you do backflow testing?
Yes. All our commercial techs include certified backflow testers. Annual testing is required on most commercial properties per Louisiana state regulations. We test, report to the city, repair any failures, and schedule next year's test. Priced per device, with volume pricing on multi-device properties.
What's your commercial emergency response time?
60 to 90 minutes for North Louisiana commercial calls. Dedicated dispatch means commercial emergencies don't wait behind residential calls. Portfolio clients with Master Service Agreements get even faster response commitments built into the contract.
Do you handle grease trap pumping and compliance reporting?
Yes. We pump grease traps on a schedule (most North Louisiana cities require 90-day or less cycle), handle the city manifest and compliance reporting, and integrate pumping with scheduled hydro jetting to keep the full grease line clean. Priced per service by trap size.
Do you offer volume pricing for property management companies?
Yes. Master Service Agreements for property management companies and portfolio clients include agreed-upon pricing, SLA-level response commitments, single invoice billing, and dedicated account management. Contact us for a custom proposal based on your portfolio size and typical service needs.
What happens if a commercial job needs to happen overnight to avoid business disruption?
Happens often — we schedule jetting, water heater replacements, and non-emergency repairs outside of business hours when requested. A commercial after-hours surcharge applies. For a restaurant that can't shut down lunch or dinner, overnight work is usually the right call and we build it into the contract.
