Water damage restoration

Commercial water damage restoration

Commercial water damage restoration follows the same steps as a house, on a larger scale and under more pressure: stop the source, extract, dry and repair, while keeping as much of the business open as possible. The job is planned around tenants, customers, inventory, building systems and the lease.

Commercial buildings add sources a home doesn't have: fire sprinkler lines and heads, roof-top HVAC units, flat roofs with interior drains, commercial kitchens and restrooms, and risers that run through many floors. One failed sprinkler head can release water at a rate no household pipe can match.

The questions are different too. Which areas can stay open? Whose insurance responds, the building owner's or the tenant's? What does the lease say about repairs and rent during the closure? A restoration company with commercial experience brings larger dehumidifiers, works after hours and in phases, and documents by suite so costs can be allocated.

Commercial water damage restoration at a glance

Extra sources: Sprinklers, flat roofs, roof-top units, risers, kitchens
Priorities: Safety, containment, keeping operations running
Insurance: Property and business-interruption policies; lease terms decide who pays
Scheduling: Phased and after-hours work is common

Signs you need commercial water damage restoration

Ceiling tiles stained, sagging or fallen
Water running down from the floor above
Wet carpet tile or raised access flooring
Elevators, electrical rooms or server rooms near the water
A sprinkler head or line that has discharged

How this differs by region

Cold climates

Frozen sprinkler lines in unheated stairwells, vestibules and attics are a leading winter cause.

Hurricane and flood zones

Ground-floor retail and parking levels flood first, and business-interruption coverage becomes the larger part of the claim.

Dense cities

In high-rises, water from one floor reaches many tenants within minutes. See city pages such as New York and Chicago.

How the job works

Stabilize
The source is isolated, power and life-safety systems are checked, and affected areas are closed off.
Extract and protect
Water is extracted and inventory, equipment and records are moved or covered.
Dry in phases
Large-capacity equipment dries the structure, often by zone so parts of the building can stay open.
Document and rebuild
Damage is recorded by suite or tenant, and finishes are restored.

What affects the cost

Every job is priced after an inspection, and your insurer may cover part of it. These are the factors that move the number:

Square footage and number of floors affected
Type of occupancy and contents
After-hours and phased work
Specialty items such as electronics and documents
Coordination with building management and insurers

What you can do before help arrives

Safe to do

Know where the sprinkler and domestic water shutoffs are before you need them
Move inventory and electronics off the floor
Notify the property manager and your insurer immediately

Stop and call

Don't shut off a fire sprinkler system without the fire department or your sprinkler contractor
Don't let staff work around wet electrical equipment
Don't discard damaged stock before it is documented

Questions about commercial water damage restoration

Who pays for water damage in a leased space?

It depends on the lease and the cause. Typically the owner's policy covers the building and the tenant's covers contents and improvements, but leases vary. Read the repair and insurance clauses.

Can we stay open during drying?

Often, in part. Crews can contain the wet area, work after hours and dry in phases. Sewage or widespread ceiling damage may require closing.
