Quick answers
- Recurring backups in kitchens or restrooms usually need camera evidence — not another blind snake.
- Grease and FOG lines fail differently than residential stacks; jetting and traps matter.
- We schedule around business hours when possible so guests and staff are not walking through a flooded floor.
- Flat-rate before we start — no mystery commercial invoices.
When to use this guide
Use this when you manage a restaurant, office, salon, medical suite, or retail space in Arlington, Alexandria, or Fairfax County and drains keep coming back after temporary clears.
What commercial drains face that homes don’t
Higher fixture counts, grease-laden kitchens, paper loads in public restrooms, and shared laterals in mixed-use buildings. A “slow sink” can be a main line story affecting multiple tenants.
What we do on a commercial call
Stabilize the backup, camera when access allows, clear with the right method (cable vs hydro jet), and document findings for your property manager or board. Emergency after-hours response is available.
How NoVA commercial stock changes the job
Older Arlington mixed-use, Alexandria storefronts, and Fairfax strip centers each have different cleanout access and HOA/landlord rules. We plan access before we promise timing.
Failure modes to avoid
Snake-only clears that return next week
Without finding the belly, grease dam, or broken section, you pay twice — once for the temporary clear and again for the emergency.
Ignoring grease interceptor maintenance
Kitchen FOG overwhelms drains and laterals. Interceptor service and drain hygiene belong on the same calendar.
