Signs of water damage in a commercial building
In commercial space, the first signs are usually overhead or at floor level: stained ceiling tiles, wet carpet tiles, and water appearing at the base of walls.
- Stained, sagging, or fallen acoustic ceiling tiles
- Water dripping from sprinkler heads, light fixtures, or air diffusers
- Carpet tiles lifting, or glue-down carpet with dark, damp areas
- Vinyl base (cove base) peeling away from the wall
- Water seeping from under a wall shared with a restroom, kitchen, or neighboring suite
- Ponding on a flat roof, or stains that follow rain
- A musty smell on Monday morning after a weekend with the air handling turned down
- Efflorescence or dampness on block walls in storage and mechanical rooms
Common causes of commercial water damage
Flat and low-slope roofs. Clogged drains and scuppers, failed seams, and leaks at rooftop HVAC curbs.
Fire sprinkler systems. Frozen pipes in unheated spaces, accidental head damage, and corroded fittings. A single head releases a large volume every minute until the valve is closed.
Restrooms and break rooms. Toilet overflows, supply lines, and water heaters, often discovered after a night or weekend.
HVAC. Condensate lines and pans above ceilings, and chilled water piping.
Neighbors. In multi-tenant buildings, the leak often starts in the suite above or beside yours.
Sewer backups. Especially in restaurants and ground-floor spaces. See sewage backup cleanup.
Storm flooding. Runoff from parking lots entering at grade-level doors. See flood damage restoration.
What commercial water damage restoration involves
Emergency response and source control
The water is stopped and the area is made safe. See emergency water damage restoration.
Assessment with the decision-makers
We walk the space with the owner, manager, or tenant, map the wet areas, and identify what is critical to operations: server rooms, records, inventory, production areas.
A plan that fits the business
The written scope covers which areas are closed off, what work happens after hours, and the expected schedule.
Extraction and removal
Water is extracted from carpet and hard floors. Wet ceiling tiles, insulation, pad, and damaged drywall are removed. See water extraction services.
Containment and drying
The affected area is sectioned off with plastic barriers so drying is efficient and the rest of the building stays usable. Equipment runs around the clock.
Daily monitoring and communication
Readings are taken and equipment adjusted on each visit, and the contact person gets an update.
Repairs
Ceiling tile, drywall, flooring, base, and paint are replaced once the structure reads dry. See water damage repair.
How commercial materials change the work
- Glue-down carpet and carpet tile. No pad, so it dries in place from the top. Carpet tiles can be lifted and replaced individually.
- Drop ceilings. Tiles are cheap to replace, and the open grid makes the space above easy to inspect and dry.
- Metal studs. They don't absorb water, but the drywall and the insulation between them do, and water pools in the bottom track.
- Concrete floors. Slow to release moisture. New flooring shouldn't go down until the slab has been tested.
- Documents and electronics. Wet paper records and equipment need prompt attention from specialists. Tell us early if they're involved.
Winston-Salem's converted factory and warehouse buildings
A good share of downtown Winston-Salem's commercial space is in former tobacco and textile industrial buildings, including the old R.J. Reynolds factory buildings that now house the Innovation Quarter. These structures are built of thick brick walls, heavy timber or concrete frames, and old wood plank or maple floors, with modern offices, labs, apartments, and restaurants fitted inside.
They behave differently when wet. Solid masonry absorbs water and gives it up slowly over weeks. Heavy timbers and thick plank floors hold moisture deep inside.
And water moves through old floor openings, shafts, and chases that are hidden behind the new finishes. Drying a space like this means longer monitoring, checking the floors below, and patience before new finishes are installed over old brick and wood.
What affects the cost of commercial water damage restoration
Cost is driven by the square footage affected, the water category, the building's construction, and the scheduling constraints of the business.
- Size. Commercial losses often cover thousands of square feet and several suites.
- Water category. Sprinkler discharge, sewage, and floodwater require more removal and cleaning than a clean supply line.
- After-hours work. Working nights and weekends to keep the business open can cost more in labor.
- Containment. Sectioning off occupied space adds setup.
- Ceiling height and access. High ceilings, lifts, and work above occupied areas.
- Contents. Moving and protecting furniture, fixtures, inventory, and equipment.
- Specialty needs. Document recovery, electronics, and regulated spaces such as food service and medical offices.
When commercial water damage is an emergency
Treat it as an emergency when water is still flowing, when a sprinkler has discharged, when water is near electrical rooms, servers, or elevators, when it's sewage, or when it's entering another tenant's space. If the fire sprinkler system has been shut down, the fire alarm monitoring company and the fire department may need to be notified, and the system must be restored by a sprinkler contractor.
After the building is dry
Keep the moisture logs and scope with the building records. Ask your roofer, plumber, or sprinkler contractor for the cause in writing, since insurers and landlords will want it. Watch ceiling tiles and base along the affected walls for a few weeks, and deal with any musty odor promptly. See mold remediation.
Commercial work is part of the same water damage restoration service we provide across Winston-Salem, including offices downtown and in West End, and shops and workplaces across the southeast side near Waughtown.
Commercial water damage questions
Can you work nights and weekends so we can stay open?
Often, yes. Extraction and demolition, which are the noisy, messy parts, can frequently be scheduled outside business hours. Drying equipment has to run continuously, so it'll be operating during the day, but affected areas can usually be sectioned off.
Who authorizes the work, the tenant or the landlord?
It depends on the lease. Generally the building owner is responsible for the structure and the tenant for its own improvements and contents. In an emergency, whoever is on site should stop the water and call both us and the property manager. We need authorization from the party responsible before non-emergency work proceeds.
Can we stay open during restoration?
In many cases, partly. It depends on the water category, how much of the space is affected, and what your business does. Clean-water losses confined to part of an office are commonly worked around. Sewage losses and food-service areas have stricter requirements.
The fire sprinklers went off. Is that water clean?
Sprinkler water has been sitting in steel pipe, sometimes for years, and usually comes out dark and oily. It's generally handled as gray water at best, so carpet pad and ceiling tiles are replaced and surfaces are cleaned.
Do you provide documentation for our insurer?
Yes. You get dated photos, a written scope, a floor plan of the affected area, and daily moisture readings, which commercial adjusters typically require.
