Commercial Water Damage: what it covers

Quick answer

Commercial water damage is a business problem as much as a building one. Portland Water Damage Restoration answers 24/7 for Portland and Multnomah County. A crew is dispatched as fast as one is available, extracts the water, dries the structure and keeps readings and photographs your manager or insurer can use.

When a pipe lets go in a house, the family moves a few things and waits. When it happens in a shop, a restaurant, a medical office or an apartment building, a lot more is at stake. Customers cannot enter. Stock sits on the floor. Tenants are displaced. A landlord, a property manager and several insurers may all need documents at once. The faster the structure dries, the shorter the downtime, and the better the record, the easier the claim.

Portland's commercial stock is varied. The older downtown and inner-eastside districts have masonry buildings with brick and timber, basement spaces and long-lived plumbing risers. Multifamily buildings stack kitchens and bathrooms over each other, so a single failure travels. Newer commercial buildings have sprinkler systems, rooftop equipment and flat roofs. Each has its own ways to leak, and each calls for its own plan.

Commercial work usually involves more people and more coordination. The first call should say what the business is, whether it can operate, who owns the building and whether there are tenants. Restoration then follows the same sequence as a house: stop the source, remove the water, map the moisture, dry to readings and report. Scale and scheduling are what differ, and the technician plans the work in phases where the business has to keep trading.

  • Water on a floor in a back room or storage area that wasn't there at closing
  • A ceiling tile stained or sagging in a corridor or office
  • A sprinkler head that has discharged, or an alarm from a flow sensor
  • Water running down an interior stairwell wall
  • A sudden rise in the water bill for the building
  • Musty smells in a lower-level suite or storage room
  • A tenant calling about water in a unit below a leaking bathroom
  • A roof drain overflowing during a storm
Our process

How our commercial water damage visit works

  1. Stop the source and secure the space

    Valves or sprinkler zones are closed by the building's responsible party or a plumber. The area is made safe for staff and tenants.

  2. Assess and phase the work

    The technician identifies critical areas, moves stock and equipment and plans extraction and drying in phases to limit downtime.

  3. Extract and map

    Water is removed from floors and carpet tile. Meters and thermal cameras map walls, ceilings and slabs across suites.

  4. Remove and dry

    Wet ceiling tile, insulation and drywall are removed as needed. Air movers and dehumidifiers dry the structure to readings.

  5. Report

    A report with photographs, readings and scope supports claims and tenant communication.

Cost

How much does commercial water damage cost in Portland?

Commercial pricing follows square footage, the number of suites and floors, the materials and how work is phased. We print no dollar figure, since none we could source describes a Portland job.

Job stories

Typical jobs for commercial water damage

A supply line fails in the back room of an older masonry shop in Portland

What homeowners notice
A shop owner finds water spreading from a back storage room toward the sales floor at opening time, with stock on low shelves and a basement stairwell wall wet.
What we do
After the line is closed, the technician moves stock, extracts water, maps the walls and slab, and phases the drying so the sales floor can keep trading while the back room is dried.
What to expect
The owner receives a log of readings and photographs for the landlord and insurer, and rebuilding is quoted separately after drying.

4 to 6 days typical visit

What should a business do in the first hour?

Stop the source if it is safe, move stock and records off the floor, photograph the damage, tell the building owner or manager and call. Note whether the business can operate. Restoration cannot begin until the source is controlled, and the plan depends on how critical the space is.

If you lease, check your lease and who is responsible for the building and contents. Notify your insurer and the landlord's contact.

Keep a record of lost sales and extra costs if you plan to claim business interruption. We do not decide what is covered.

  • Close the source if safe
  • Move stock, records and electronics
  • Photograph everything
  • Notify landlord, manager and insurer

How are older masonry buildings dried?

Brick, stone and concrete hold water and release it slowly, so drying takes longer and relies on dehumidification and monitoring rather than speed. Plaster and timber behave differently from modern drywall. The technician chooses equipment and sets readings suited to each material.

Portland's older downtown and inner-eastside buildings include masonry construction. Walls can be thick, and basements and sub-basements are common.

Salts and efflorescence can show on masonry as it dries. That is normal and is cleaned later.

What about apartment buildings?

In a multifamily building, one failure can reach several units. Fast shutoff, clear communication with tenants and a vertical map of the water path are the priorities. Responsibility between owner, association and tenants depends on leases and policies, so records matter more than usual.

Access to units is a practical challenge. A manager or association can arrange notices and entry so drying is not delayed.

We coordinate phases so that tenants can return as areas dry, wherever the building allows it.

What records does a commercial claim need?

A claim usually needs dated photographs, a list of damaged contents and materials, the moisture readings and the scope of work, plus any records of lost sales and extra expenses. Keep invoices from every trade. Whether the loss is paid, and how much, is decided by your insurer under your own policy.

Ask for the log of readings and photographs at each visit. These show how the water moved and how drying progressed, and they make a long loss easier to explain.

If the building has several tenants, each will want its own record. A written map of which areas were wet and when helps.

How does phasing keep a business open?

Phasing means drying one area while another keeps trading: closing a back room while the sales floor stays open, or working on one floor of an apartment building at a time. It depends on where the water went and on safety. The technician plans phases with you before equipment is placed.

Not every loss can be phased. A flooded retail floor or a restaurant kitchen may need to close for extraction and the first days of drying.

The more you tell the dispatcher about opening hours and critical areas, the better the plan.

What about flat roofs and roof drains?

Flat and low-slope roofs rely on drains, and a clogged drain pools water that finds seams and penetrations. The first heavy rain of the season often exposes it. Clear drains before October, and after the leak, expect the roofer and the restoration crew to work in tandem.

Standing water adds weight to a roof. Water that sits for days can also push through membrane seams and into ceilings below.

A building manager's seasonal checklist should include drains, scuppers and roof penetrations.

Options

Types and options for commercial water damage

Supply-line and riser failures

A burst line or valve in a stacked building sends water down through several floors. Speed of shutoff and mapping the vertical path matter.

Sprinkler discharge

A tripped or damaged head can release large amounts of water quickly. The water is usually clean, but volume and spread are big.

Multnomah County

Why commercial water damage is different in Portland metro

Portland's older downtown and inner-eastside districts include masonry buildings with long-lived plumbing risers and basements that have seen decades of use. Those are the places where a leak is most likely to travel unseen, and Census-based estimates put roughly 45 percent of the city's housing, not its commercial space, before 1960.

The central city sits low beside the Willamette. The 1996 flood crested at 28.6 feet in Portland and came within a few inches of overtopping the downtown seawall, which was sandbagged. Water table and river levels matter for basements near the waterfront.

The Columbia-side levee system runs about 27 miles from North Portland through Gresham and Fairview to Troutdale, and its flood-map status is an open question we could not confirm. Businesses in that corridor should ask their insurer about flood cover, which is a separate policy from the one that covers a burst pipe.

Because Portland's rain falls mostly between October and March, commercial roof and drainage problems cluster in the same months as residential ones. A manager with several buildings can plan checks in September, when July and August have been dry and the first storms have not yet arrived.

FAQ

Commercial Water Damage FAQs

Can you work after hours so we can keep trading?

Often the work can be phased around operating hours. Say so on the call so the plan can be made, with timing depending on crew availability.

Do you deal with the landlord and insurers?

We provide photographs, readings and a scope you can share. Coverage and responsibility are decided by the landlord, tenants and insurers.

What about inventory and equipment?

Move what you can off the floor. We can advise which items may be salvageable, but a specialist may be needed for electronics and documents.

Is sprinkler water clean?

Usually clean at first, though it picks up contaminants from pipes and surfaces. The technician assesses the category.

Will drying disrupt other tenants?

Equipment is loud and runs continuously, so tenants may notice. Notice and phasing help.
