The West End Historic District runs along West Seventh Street, with homes from the 1800s into the early 1930s, and the West Sixth Street and Mayes Place district sits in the town's earliest residential section. Census estimates put the median home in the city at around 1981. New subdivisions keep going up as well, such as Independence at Carter's Station, Ridgeview Oaks off Tom Sharp Road and Baker Creek off Mooresville Pike. For you, that range matters. An older house has usually had its plumbing and wiring changed piece by piece over the years. A newer one is more likely to be on its original equipment, reaching its first round of repairs. ### Water and sewer Columbia Power & Water Systems (CPWS) supplies water to the City of Columbia and much of Maury County, and it draws that water from the Duck River. CPWS owns the mains and everything up to and including the meter. The pipes on your side of the meter, from the meter box to the last faucet, are yours to keep up. Sewer inside the city is run by the City of Columbia's Wastewater Department. The line that carries waste from your house to the public sewer main is a private service line, and it belongs to the property owner. ### Electric and gas utilities CPWS also provides electric service in Columbia, along with parts of Spring Hill and other areas of Maury County. It buys its power from the Tennessee Valley Authority, and the electric meter on your house is CPWS property. Natural gas in Columbia comes from Atmos Energy. A house on a gas line may have a gas furnace, water heater or range, while an all-electric house runs everything on CPWS power. Which one you have changes what can go wrong and what a fix involves. ### The ground under Columbia Columbia sits in Tennessee's Central Basin, where limestone lies under most of the land. Rainwater slowly dissolves that rock, and sinkholes are common across the basin as a result. Ground that settles unevenly puts strain on anything buried in it: the water line from the meter, the sewer line to the street, and the copper lines that run to an outdoor AC unit. Limestone is also the main source of the calcium that makes water hard, which is worth knowing if you own a water heater. ### Seasons that are hard on a house January's average low in Columbia is below freezing, and summers are hot and humid. When a freeze is coming, the National Weather Service advises wrapping, draining or slowly dripping exposed pipes, and CPWS recommends insulating pipes in unheated spaces like crawl spaces. In summer, long humid stretches keep air conditioners running for hours and their drain lines working constantly. ### Permits and inspections Inside city limits, the City of Columbia's Development Services office issues permits, and its building inspectors review plans and inspect building, plumbing, mechanical and gas work. Plumbing and mechanical work are permitted separately. Outside city limits, Maury County's Building and Zoning Office handles building permits. Electrical permits in Tennessee go through the State Fire Marshal's Office, except where the state has approved a local program, so it's worth asking which one covers your address. ## Neighborhoods we serve in Columbia Downtown Columbia, West End, West Sixth Street and Mayes Place, Highland Park, Independence at Carter's Station, Ridgeview Oaks, Baker Creek, Bear Creek Overlook, and everywhere else in Columbia. ## Businesses and builders in Columbia [Commercial work](https://roothousemechanicals.com/commercial), [new construction](https://roothousemechanicals.com/new-construction) and [renovations](https://roothousemechanicals.com/renovations). ## Questions about Columbia ### Do you work everywhere in Columbia? We work throughout Columbia, from downtown to the newer subdivisions on the edges of town. If you have a Columbia address outside city limits, call or text (615) 426-9344 and we'll tell you honestly whether we can get to you. ### Who provides water, power and gas in Columbia? Columbia Power & Water Systems (CPWS) provides water and electric service in the city, and Atmos Energy provides natural gas. Sewer inside city limits is run by the City of Columbia's Wastewater Department. Your monthly bills show which ones serve your address. ### Do you work on older homes in Columbia's historic districts? Yes. Older houses often have plumbing, wiring and ductwork that were added or changed in stages, so we trace what's there before we recommend anything. If a job changes the outside of a house in one of the city's historic districts, the Historic Zoning Commission may need to review it, so ask the city before work starts. ### Will my job in Columbia need a permit? Many plumbing, HVAC, gas and electrical jobs do. Inside city limits, permits come from the City of Columbia's Development Services office. Outside city limits, start with Maury County. We'll tell you what your job needs when we give you the price. ### Do you work with builders and businesses in Columbia? Yes. We handle plumbing, HVAC and electrical for businesses, and rough-in through trim-out for builders.
