Water in a house near the lake, a split supply line in a subdivision off Highway 92, a leak under an old house on Collins Avenue: each one starts the same way, with a phone call and a conversation with a local restoration provider. This page is about water damage restoration in Acworth, Georgia, and about the things that are true of this city and not of the next one down Cobb Parkway.
Water Damage Cobb County is a free referral service that connects callers with independent local water damage restoration providers. It is not a restoration contractor. The provider you are connected with looks at the damage, prices the job and does the work, and the decision to hire is yours.
What follows is laid out for someone with a wet floor reading on a phone, so each section stands on its own. It covers the two lakes and the creeks behind them, what flood insurance does and does not do, why the city sells you power while the county sells you water, the repair rules in the two historic districts, the permit office, and what the weather records say this far north in Cobb County.

A city that is six percent water
Nothing is more true of Acworth than its water. The Census Bureau figures quoted in the city’s Wikipedia entry put the city at 8.8 square miles, of which 0.54 square miles, about 6 percent, is water. The city lies along the southeastern banks of Lake Acworth and Lake Allatoona, and it is often called the Lake City.
The two lakes are different things. Lake Acworth is a 260-acre man-made lake behind a dam the U.S. Army Corps of Engineers built in 1950. It holds back Proctor Creek and Butler Creek and flows out into Lake Allatoona. Acworth Beach is on its north shore, and South Shore Park is reached from Ragsdale Road.
Lake Allatoona is far larger, a 12,010-acre Corps of Engineers reservoir on the Etowah River, and flood control is one of its stated purposes. A reservoir built for flood control is built to rise. Its summer pool is 840 feet above sea level and it is drawn down to 823 feet in the cold months. The highest level on record is 861.19 feet on April 9, 1964, more than 21 feet above summer pool. The lake figures here come from Wikipedia’s entries for the two lakes, a secondary source.
For a homeowner the point is simple. Rain that falls on the north end of Cobb County drains toward these lakes through Proctor, Butler and Allatoona creeks, and a house near any of them has a flood question that a house on a ridge does not. The flood damage restoration in Cobb County page covers what a provider does after rising water has been through a building.
September 2009 at the north end of the county
The flood that Cobb County’s stormwater office still cites when it explains flood risk peaked here on September 21, 2009. The U.S. Geological Survey’s report on that flood lists its gauge on Allatoona Creek at Stilesboro Road near Acworth peaking at 23.90 feet and 16,600 cubic feet per second. Butler Creek, one of the two creeks that Lake Acworth holds back, reached 14.27 feet at the Mack Dobbs Road gauge near Kennesaw.
USGS says both readings were beyond the 0.2 percent annual chance flood, the level often called the 500-year flood. It also says the flows on Allatoona, Noonday and Butler creeks raised Lake Allatoona more than 13 feet above full pool.
Cobb County’s stormwater office says that flood put water into more than 1,600 homes. That is a countywide count, not an Acworth one, and no figure for the city alone has been published in the sources checked for this page. Noonday Creek, which also ran far above its earlier peaks that week, lies east of the city and is covered on the water damage restoration in Kennesaw, GA page.
Does insurance cover water from the lake or a creek?
Cobb County tells residents two things that surprise people. Most homeowners insurance policies do not cover flooding, and a flood insurance policy typically has a 30-day waiting period before it takes effect. A flood policy bought the week a storm is forecast is unlikely to help with that storm.
The line that matters is where the water came from. Water that rises from a lake or a creek and comes in across the ground is flooding. Water from a burst pipe, a failed water heater or a washing machine hose is a plumbing loss, and it is handled under the homeowners policy and that policy’s own terms. A sewer backup is a third case: the Insurance Information Institute says a typical homeowners policy does not cover it and flood insurance does not either, so the cover has to be bought separately or added by endorsement.
To find out whether a house sits in a mapped flood zone, use the Search FEMA Floodplain tool on Cobb County’s flood maps page. The county maps the Special Flood Hazard Area, the ground with a 1 percent chance of flooding in any year, and its Stormwater Management Division takes questions about flood depth.
About the county’s flood insurance discount
Cobb County says its Community Rating System classification of 7 gives residents a 15 percent discount on flood insurance premiums. That is the county’s program. Whether a policy on a house inside the Acworth city limits receives it was not confirmed in the sources checked for this page, so ask your insurance agent before counting on it.
No provider and no referral service can tell you what your insurer will pay. What a provider can do is document what was wet and what was done about it, and the sample homeowners form (ISO HO-3) published by the Insurance Information Institute lists protecting the property from further damage among the owner’s duties after a loss. A real policy can read differently from the sample, so check your own.
The city sells you power, the county sells you water
This is the split that confuses new residents. The City of Acworth runs its own electric utility, Acworth Power, which serves customers in the city and in parts of Cobb and Bartow counties. Water and sewer are another matter: the city’s own Power and Public Works page sends water and sewer problems to Cobb County Water and Sewer. One address, two utilities, two sets of people to reach.
The Cobb County Water System publishes a general number and an emergency dispatch line, and it asks customers to use dispatch only for a sewer backup in the home or the street, or a broken water line that is gushing or leaking severely. A slow drip at the meter box is not what dispatch is for.
Who pays for the pipe depends on which side of the meter it is on. The county says a leak after the water meter is the property owner’s responsibility and a leak before the meter is the county’s to repair. It offers a partial leak credit on the bill once in a rolling 12 months, and it says that credit never takes the cost of plumbing repairs into account. The county’s pages do not spell out the same split for the sewer line between a house and the main, so ask the dispatcher which part is yours.
| What is happening | Who deals with it |
|---|---|
| Someone is in danger, or water is near live wiring you cannot switch off safely | 911 |
| Sewage is backing up into the house or the street | Cobb County Water System emergency dispatch |
| A water line is broken and gushing on the street side of the meter | Cobb County Water System emergency dispatch |
| A pipe, fitting or appliance is leaking on your side of the meter | The owner: shut the water off, then a plumber for the pipe and a restoration provider for the wet building |
| The power is out | Acworth Power, the city’s electric utility, if it is the one that bills you |
| A storm drain in a city street is blocked or overflowing | City of Acworth Stormwater Division, which maintains stormwater infrastructure in city rights-of-way |
| A question about your flood zone or flood depth | Cobb County Water System, Stormwater Management Division |
| Floors, walls, ceilings or belongings are wet | A local restoration provider: the number on this page connects you with one |
The utilities deal with their pipes and wires. None of them dries a house. When sewage is involved, the sewage cleanup in Cobb County page explains why that water is handled differently from a clean supply line leak.
The utility fixes its line and a provider deals with the wet house: call to be connected with a local restoration provider.
Old houses on Collins Avenue and Park Street
Acworth protects two local historic districts, Collins Avenue and Park Street. The city’s historic preservation page says every change to a property in them, or to an individually landmarked site, needs a Certificate of Appropriateness from the Historic Preservation Commission. The Collins Avenue district has also been on the National Register of Historic Places since July 5, 2001.
What counts as a change is set out in the city’s design guidelines booklet. All work that alters an exterior feature of a designated property needs design review, and the booklet names repair and rehabilitation in that list. Interior alterations, a change of use, repainting and ordinary maintenance do not. The booklet also warns that a stop-work order may be issued if work starts before approval.
That wording is good news for an owner with a wet floor. Extracting water, drying a room, pulling wet carpet and replacing interior drywall are interior work, and the guidelines place interior alterations outside design review. The questions start when the repair reaches the outside of the house: siding, windows, a porch, a roof or the foundation.
Water under a house on piers
Where a historic house stands on an open pier foundation, the city’s guidelines ask owners to keep it open wherever possible. Rebuilding a foundation, placing material between piers, and painting or stuccoing a foundation are listed as changes that need a Certificate of Appropriateness. Repointing a brick foundation, repainting one, or repairing infill that is already there are not. Ask the Historic Preservation Commission before closing in a crawl space after a leak.
One caution applies to any older house, protected or not. The EPA warns that older homes may contain asbestos or lead in their building materials, which matters before anyone tears out walls, ceilings or flooring. Tell the provider the age of the house on the first call.
Most of Acworth was built after 1990
The historic districts are the exception. The Census Bureau’s American Community Survey for 2020 to 2024 estimates about 9,362 housing units in the city. Of those, 2,987 were built from 2000 to 2009 and 2,621 in the 1990s, together 59.9 percent. Add the 2010s and the share built from 1990 to 2019 comes to 76.6 percent.
Old houses are scarce by comparison: 13.5 percent of units predate 1980 and 2.1 percent predate 1950. These are survey estimates with margins of error, but the shape is clear. A house from the 1990s or 2000s is roughly 17 to 36 years old in 2026, an age at which an original water heater, a supply line, an appliance hose or a shut-off valve is a common starting point for a leak.
The city’s 2022 Comprehensive Plan describes the housing as mostly single-family, with a little over a quarter multi-family or “missing middle”. It also says that since 2010 the share of occupied homes that are rented went from 29 percent to 39 percent. A renter with a leak should tell the landlord or the property manager first, in writing if possible, since the building and its insurance are the owner’s.
How the city maps itself
The same plan divides Acworth into character areas, and they describe the buildings a provider may be walking into better than a ZIP code does.
- Central Historic District: the old town center, with historic houses, city offices and small family businesses along a busy railroad corridor.
- North and South Main Street corridors: homes mixed with retail, warehouses and light manufacturing. The plan says many structures on the mile-long South Main strip are older.
- Cobb Parkway: a four-mile run of big-box stores and large retail developments along US 41 that marks the city’s southern boundary.
- The I-75 interchanges: hotels, restaurants and gas stations at Exit 277 (Highway 92) and Exit 278 (Glade Road) that quickly give way to single-family homes.
- North and South Perimeter Living: the plan’s name for the outer residential edges of the city, which it describes as largely built out.
- Campus Living: the area around Blue Springs Station, North Cobb High School, Awtrey Middle School and the North Cobb Regional Library.
- New McEver: the city’s one significant industrial area, by New McEver Road and Huddleston Bridge Road.
Rebuilding in Acworth: permits and codes
Drying a building is one job. Putting it back together is another, and inside the city limits the second one runs through the City of Acworth Development Department, whose Building and Inspections staff work from City Hall. The city publishes separate residential applications for remodeling, electrical, plumbing and mechanical work, and it links to a Construction Permit Self-Service site.
The codes changed recently. The city’s sheet of code editions in effect from January 1, 2026 lists the 2024 International Building, Residential, Plumbing, Mechanical and Fuel Gas Codes and the 2023 National Electrical Code, each with 2026 Georgia amendments, and it says all construction activity must comply.
What the city does not publish in plain text is the point at which replacing drywall or flooring after a leak needs a permit. Ask the office before the rebuild starts, and ask the provider who will be pulling any permit. The state board that licenses residential and general contractors warns homeowners against pulling their own permit for a job a contractor will do, because whoever obtains the permit takes on most of the liability.
Two more checks are worth a minute. Georgia’s Attorney General says electricians, plumbers and heating and air contractors must hold a state license, so ask for the number if the repair includes that work. And an Acworth mailing address does not prove the house is inside the city: an address in unincorporated Cobb County goes to the county’s Community Development office for permits, not to City Hall, and an address that turns out to be in a neighboring county goes to that county’s office.
Cold, rain and wind this far north in Cobb
Weather figures only mean something with the station named. None of the figures here come from a station inside the city. At Allatoona Dam 2, a nearby NOAA station named for the dam that holds back Lake Allatoona, the 1991 to 2020 normals give 51.78 inches of precipitation a year. March, January and July are the wettest months there at just under 5 inches each, and October is the driest at 3.42 inches.
The cold is the bigger surprise. The same normals count about 68 days a year with a low of 32 degrees or colder at Allatoona Dam 2, roughly double the figure at Atlanta’s airport. At McCollum Field, the airport station near Kennesaw, the low on December 24, 2022 was 7 degrees and the afternoon high was 24. Consumer Reports gives 20 degrees as the temperature below which frozen pipes generally occur, and names pipes in unheated basements, attics and garages as the ones most at risk.
Wind brings water too. The National Weather Service says Tropical Storm Zeta crossed north Georgia in the early hours of October 29, 2020 with widespread gusts of 40 to 60 miles per hour, and that many trees fell onto homes and businesses. A tree through a roof in the rain is a water damage call as much as a roofing one.
Then there is what happens after the water stops. EPA guidance says that if wet materials are dried within 24 to 48 hours of a leak, in most cases mold will not grow, and it advises keeping indoor humidity under 60 percent, ideally between 30 and 50. That window is the reason drying is treated as urgent. The mold remediation in Cobb County page takes it from there.
What restoration costs, in two paragraphs
No published price list exists for Acworth, or for Georgia, in the sources checked for this page. The nearest figures are national estimates from HomeAdvisor, on a page it shows as updated June 17, 2026: an average of $3,868, with most homeowners spending between $1,383 and $6,369. By the type of water, HomeAdvisor puts drying at about $3.50 a square foot for clean water, $5.25 for gray water and $7.50 for black water.
Those are HomeAdvisor’s numbers, not this site’s and not any provider’s. Water Damage Cobb County sets no prices. The provider you are connected with prices the job after seeing how far the water went, how dirty it is and what has to come out, so ask for the estimate in writing before work starts.
While you wait, and how the call works
A few things are safe to do before anyone arrives. The emergency water removal in Cobb County page goes through each one in more detail.
- Stop the water if it is from plumbing. The main shut-off valve is usually at the water meter or where the main line enters the house.
- Leave the electricity alone unless the panel can be reached from a dry place. CDC guidance is never to switch power on or off while standing in water.
- Stay out of water that came from a creek, the lake or a sewer. Treat it as contaminated.
- Photograph every wet room and damaged item before moving anything.
- Lift what you can off the floor: rugs, boxes, furniture legs, anything that soaks water up.
The call itself is simple. It is free, and it connects you with an independent local provider; this site does none of the restoration work itself. Participating providers may offer 24-hour emergency service, but availability depends on the provider and the area and is not guaranteed. Before hiring, ask the provider for proof of the license and insurance the work requires.
For anything that threatens life, call 911 first. Kennesaw Acworth 911 handles emergency communications for both cities; it dispatches police and transfers fire and medical calls to the county. The Cobb Emergency Management Agency coordinates disaster protection for county residents. For other parts of the county, start from the water damage in Cobb County homepage.

Questions people ask
Who do I call first for a sewer backup in Acworth?
Call the Cobb County Water System’s emergency dispatch line. The City of Acworth’s own Power and Public Works page sends water and sewer problems to the county. The county asks customers to use dispatch only for a sewer backup in the home or street, or a water line that is gushing. Once the line is being dealt with, a restoration provider handles the contaminated rooms.
Is the leak my responsibility or Cobb County Water’s?
It depends on the side of the meter. Cobb County says a leak after the water meter is the property owner’s responsibility, and a leak before the meter is the county’s to repair. The county offers a partial leak credit on the water bill once in a rolling 12 months, and says the credit never takes plumbing repair costs into account.
Does my homeowners insurance cover flooding from Lake Acworth or a creek?
Probably not under the homeowners policy alone. Cobb County tells residents that most homeowners insurance policies do not cover flooding, and that a flood insurance policy typically has a 30-day waiting period before it takes effect. Water rising from a lake or creek is flooding. A burst pipe is a different kind of loss under the homeowners policy. Read your own policy or ask your agent.
How do I find out whether my Acworth home is in a FEMA flood zone?
Cobb County offers a Search FEMA Floodplain tool on its flood maps page. It shows the Special Flood Hazard Area, the ground with a 1 percent chance of flooding in any year. The county’s Stormwater Management Division takes questions about flood depth. Georgia’s Environmental Protection Division also points owners to georgiadfirm.com for a property-specific flood risk snapshot.
Do I need a permit from the City of Acworth to rebuild after water damage?
Ask before the rebuild starts. Permits inside the city come from the Development Department’s Building and Inspections staff at City Hall, with separate residential applications for remodeling, electrical, plumbing and mechanical work. The city does not publish in plain text the point at which drywall or flooring replacement needs one, so confirm with the office. The permit question is about the rebuild, not about extracting water and drying the building.
My house is on Collins Avenue or Park Street. What repairs need approval?
Both are local historic districts, and the city says changes to property in them need a Certificate of Appropriateness. The city’s design guidelines apply that to work that alters an exterior feature, including repair or rehabilitation. Interior alterations, repainting and ordinary maintenance do not need design review. Rebuilding a foundation or placing material between piers does. Starting before approval can bring a stop-work order.
How fast does mold start after a leak?
EPA guidance says that if wet materials are dried within 24 to 48 hours, in most cases mold will not grow. The Georgia Department of Public Health uses the same window and gives water from a burst pipe as its example. EPA also notes the 48-hour mark is a guideline, not a guarantee either way, which is why wet walls and floors are checked with a moisture meter instead of by touch.
Will the health department inspect mold in my house or rental?
No. Cobb & Douglas Public Health says it has no authority to address mold in private residences or rental properties. The Georgia Department of Public Health says indoor air quality is not a regulated program in the state, and it points renters to Georgia Legal Aid and the Georgia Landlord Tenant Handbook. Finding and fixing the moisture falls to the property owner.
What does water damage restoration usually cost?
There is no published Acworth figure. HomeAdvisor’s national estimates, on a page updated June 17, 2026, give an average of $3,868 and a typical range of $1,383 to $6,369, with about $3.50 a square foot for clean water, $5.25 for gray water and $7.50 for black water. Those are HomeAdvisor’s numbers. The provider you speak with prices the actual job.
Is this a restoration company?
No. Water Damage Cobb County is a free referral service. Calling the number on this site connects you with an independent local water damage restoration provider. That provider, not this site, assesses the damage, gives the price and does the work. This site does not warrant or guarantee any provider’s work, and you should confirm the provider carries the license and insurance the job requires.
My address says Acworth but I am outside the city limits. Who handles permits and water?
A mailing address is not the same as the city limits. If the house is in unincorporated Cobb County, building permits go through Cobb County Community Development’s Development and Inspections division, not Acworth City Hall. Water and sewer come from the Cobb County Water System either way, since its services reach customers inside the City of Acworth as well as in unincorporated Cobb County. An address in a neighboring county deals with that county’s offices.
What should I do while I wait for a provider to arrive?
Shut off the water at the main valve if the source is plumbing. Do not touch the electrical panel unless you can reach it from a dry place. Keep out of water that came from a creek, the lake or a sewer. Photograph the damage, then lift rugs, boxes and furniture off the wet floor. If anyone is in danger, call 911.
