Commercial plumbing repair for DFW tenants — clogged drains, fixtures, water heaters, and everyday pipe work.
Drain backed up? Pipe burst? Water heater quit?
Toilet clogged before the lunch rush. Floor drain backing up in the warehouse. Water heater quit on a Friday. Pipe spraying behind a wall. Same-day commercial plumbing across Farmers Branch, Addison, and Lewisville — we answer the phone and get a truck moving.
What we do
Commercial plumbing repair for tenants in warehouses, strip malls, retail, and small office space. The everyday stuff — clogged drains, leaky fixtures, water heater service, small-diameter pipe work — plus the occasional surprise that comes with aging DFW buildings.
Who we work for
Commercial tenants who are responsible for their own plumbing under a triple-net lease. That is most DFW tenants, most of the time. The landlord has the roof and the exterior; the rest of it is on you, and that is where we come in.
What we fix
Clogged drains, backed-up toilets, and slow-draining floor drains in retail and warehouse space
Leaking faucets, valves, and commercial fixtures
Commercial water heater service and replacement
Running and damaged toilets that drive up a water bill
Small-diameter pipe repairs under slabs, in walls, and above ceiling grids
Emergency shutoffs and leak containment when something is spraying
Why commercial tenants call us
You need it fixed that day. Dave's own tenants have been getting this service for years because the alternative — a tenant running around calling three different plumbers, hoping one shows up before the lunch rush — is not a business plan. Big Dog Tenant Services productizes what already works: one number, same-day dispatch, one invoice.
Plumbing — common questions
My toilet is clogged and we open at 11 — can you get here in time?+
We try. Same-day dispatch is how this business was built, and plumbing calls with a morning deadline get routed that way. Call the number on this page and we will tell you what the window looks like.
Do you service commercial water heaters?+
Yes — repair, flushing, element replacement, and full replacements on commercial water heaters typical of retail and light industrial spaces.
Who is responsible for plumbing under a triple-net lease?+
In most triple-net leases, the tenant is responsible for the plumbing inside the leased space. The landlord usually covers the building envelope and main supply. Check your lease for specifics — and call us either way.
Do you handle small-diameter pipe repairs and fixtures?+
Yes. Clogged drains, damaged toilets, leaking valves, faucet and fixture replacement, and small-diameter pipe repair above the ceiling or under slabs are all regular work for us.
Where we work
Commercial tenants across Farmers Branch, Addison, and Lewisville. Serving DFW — no residential.
