Commercial Plumbing in Boulder, CO
A plumbing problem at a commercial property carries different stakes than a home repair. A restaurant with a clogged grease trap or an office with a leak in a shared wall needs a technician who understands commercial fixtures and can work around business hours. Boulder Express Plumbing handles both routine and urgent commercial plumbing across Boulder.
Local Causes.
Boulder's mix of older downtown commercial buildings and newer build-outs in business parks near the Diagonal Highway means commercial plumbing calls range widely, from a decades-old cast iron stack in a University Hill storefront to a modern build-out with entirely different fixture standards.
Restaurants and food service properties see a specific recurring issue: grease trap backups that seem sudden but are actually the result of gradual buildup finally reaching a tipping point. Regular maintenance catches this before it becomes an emergency closure.
Common Warning Signs.
A grease trap backing up or overflowing.
Multiple fixtures on the same line slowing down at once.
A leak in a shared wall or ceiling affecting more than one tenant space.
Water pressure issues affecting an entire floor or suite.
Backflow concerns tied to a commercial kitchen or irrigation system.
Aging fixtures or piping in an older downtown building nearing end of service life.

Finding the Actual Problem.
For commercial leak calls, we often start with a video camera inspection since commercial buildings tend to have longer, more complex line runs than a residential property. That's a faster and less disruptive way to find the actual source than opening walls speculatively.
We also work around your operating hours where possible, since a restaurant or retail space often can't afford unplanned downtime during business hours for anything short of a genuine emergency. Before we arrive for an active leak, shutting off the water at the property's main valve, if a staff member knows its location, limits damage in the meantime.
For multi-tenant buildings, we also check whether an issue is isolated to one suite or affects shared plumbing infrastructure serving multiple tenants, since that changes who needs to be looped in before work starts.

Straight Answers.
Yes, we regularly coordinate directly with property managers on multi-tenant buildings, and we're glad to set up a standing maintenance schedule rather than handling everything as one-off emergency calls.
Yes, and it's genuinely worth doing on a schedule rather than waiting for a backup. A trap serviced regularly rarely turns into an emergency closure.
Yes, backflow prevention is often a code requirement for commercial food service and irrigation connections, and we handle both testing and repair.
Yes, a genuine emergency like an active leak or complete loss of water service gets an urgent response regardless of the hour, since a closed business often can't wait until normal service hours.
Yes, we provide detailed invoices with the documentation most businesses need for their own records, expense reporting, or property management accounting systems.
Often Booked Together
A recurring line issue at a commercial property is often worth a camera inspection before committing to a repair method, and an actual line failure is covered under sewer line repair. Property-specific quirks fall under general plumbing repair, and properties with irrigation or fire suppression connections typically also need backflow testing.
For scheduled commercial maintenance or an urgent leak affecting your business, call Boulder Express Plumbing. We'll work around your hours wherever the situation allows, and we'll always confirm scope and cost with you or your property manager before starting work, whether it's a single suite or a full building we're servicing.
