We Exceed Expectations
Full Nelson serves Smithville homeowners with plumbing, heating and air conditioning work built on clear explanations and technical skill. Smithville spans 15.67 square miles across Clay and Platte counties in western Clay County, on the Little Platte River, and counted 10,406 residents in the 2020 census.
The city has roughly doubled since the turn of the century, from 5,514 residents in 2000 to 8,425 in 2010 to 10,406 in 2020. That means Smithville homes range from nineteenth-century downtown properties to subdivisions finished in the last few years, and the work varies accordingly. Learn more about our company.

Expert Plumbers
Plumbing Services in Smithville, MO
Smithville was established in 1822 by Humphrey “Yankee” Smith and was originally called Smith’s Mill, renamed later to avoid confusion with another Missouri settlement of the same name. The Downtown Smithville Historic District is listed on the National Register, and properties in and around it carry plumbing that has been modified across many decades.
The single fact that shapes plumbing here more than any other is the lake. The Little Platte River is dammed east of the city to create Smithville Reservoir, and that reservoir is the water supply for Smithville, Missouri. Surface water from a reservoir behaves differently at the tap than groundwater does, particularly for taste, odor and seasonal variation. Full Nelson’s licensed plumbers work across the whole range of Smithville property, in town and out.

Drain Cleaning
Drain problems in Smithville split by era. Downtown and older properties have drain lines that have scaled internally over many decades and lost usable diameter, with roots working the joints. Newer subdivision homes have modern pipe where the problem is more often slope and settling than deterioration. Clearing the blockage is straightforward. Knowing which of the two you are dealing with determines whether you will be calling again. Full Nelson provides drain cleaning services and identifies the underlying cause.
For more serious issues, we offer:
- Drain cleaning
- Rooter services
- Clogged sinks
- Showers
- Floor drains
-
Sewer Repair and Replacement
Sewer laterals serving Smithville’s older core have been in the ground long enough that clay tile and cast iron are both past the service life they were built for. Properties on the outskirts may not connect to a municipal main at all. Camera inspection settles what is actually happening rather than guessing from symptoms. Full Nelson runs the camera, shows you the footage, and explains your sewer repair options before quoting work.
Our services include:
- Sewer line repair and installation
- Sewer video inspection
- Trenchless excavation using pipe bursting technology
-
Sump Pumps and Battery Backup Systems
Smithville Dam was authorised in 1965, built between 1972 and 1977, and began impounding water in 1979. The U.S. Army Corps of Engineers Kansas City District built it primarily for flood control, with an earthen dam 4,000 feet long and 105 feet high holding a maximum capacity of 246,500 acre-feet. That structure manages the river. It does not manage the water moving through the soil under your house after four inches of rain.
Properties near the Little Platte River and on the low ground around the reservoir see groundwater that higher lots do not. Full Nelson installs sump pumps and battery backup systems sized to what your lot actually produces, with battery backup so the pump keeps running when the storm takes the power out.
Our services include:
- Sump pumps
- Battery backup systems
-
Gas Leaks and Gas Repairs
Natural gas heats most homes inside Smithville, while properties further out frequently run propane instead. Both carry the same risks at connections, corroded fittings and buried lines. If you smell the rotten egg odor of natural gas, hear hissing near an appliance, or see vegetation dying over a buried line, call immediately. Full Nelson locates the leak, repairs it, and pressure tests the system before leaving.
Our services include:
- Gas leak detection
- Gas leak repair
- Gas line testing
- Gas line installation
-
Toilet Repairs and Replacements
A running toilet adds hundreds of gallons to the monthly bill. Repeated clogs usually point to the drain line or vent stack rather than the fixture itself. Weak flushes often trace to mineral deposits blocking rim jets, which builds faster where water carries more mineral content. Full Nelson diagnoses the actual cause and completes repairs that address it.
Our services include:
- Toilet repairs & replacements
- Flapper replacements
- Toilet rebuilds
- Water-efficient toilets
-
Faucets and Shower Valves
Dripping faucets and shower valves that will not hold temperature indicate worn cartridges and seals, and mineral content accelerates that wear. In older downtown properties the valve body itself may be obsolete with no parts available. Full Nelson can tell you quickly which situation you are in, and we handle faucet and shower valve work throughout the house.
Our services include:
- Kitchen faucets
- Bathroom faucets
- Shower valves
- Tub fixtures
-
Water Filtration
Smithville is one of the few communities in the metro whose municipal supply comes from a reservoir it can see. Smithville Lake, at 7,190 acres with 175 miles of shoreline, is the largest body of water in the Kansas City metropolitan area and the water supply for the city. Surface water from a reservoir varies seasonally in a way groundwater does not, and taste and odor complaints tend to follow those cycles. A whole-home system treats the water where it enters the house so every fixture benefits. Full Nelson tests your water and recommends filtration based on measured results rather than assumptions.
Our services include:
- Whole-home water filtration systems
- Water quality assessment
- Filtration solutions
-
Water Softeners
Hard water leaves scale on shower doors, spots on glassware and mineral deposits inside water heaters and pipes, cutting appliance efficiency and shortening equipment life. Properties on private wells around the lake and out into the county often carry noticeably more hardness and more iron than the municipal supply. Full Nelson measures hardness at your address and sizes a softener to your household and your actual water.
Our services include:
- Water softeners
- Water softener installation
- Water softener service
-
Well Pumps and Well Tanks
Smithville’s 15.67 square miles include substantial rural acreage, and properties out toward the lake and beyond the mains draw from private wells. When a submersible pump fails or a pressure tank bladder ruptures, the property loses water entirely, and on an acreage that also means no water for livestock or outbuildings. Full Nelson diagnoses well system faults and replaces pumps, pressure tanks, pressure switches and related components.
Our services include:
- Well pumps & Well tanks
- Low water pressure issues
- Short cycling
- Pump failure
Expert Plumbers
Excavation Services Smithville, MO
Rural and semi-rural property means longer buried runs between the main and the house, more septic systems, more private wells and more ground to work across. Full Nelson provides excavation services suited to that kind of property and recommends trenchless methods where site conditions allow.

Water Main Line Repair and Replacement
The water service line from the meter to the house carries every gallon the household uses, and on acreage that run can be very long. Corrosion, root intrusion and ground movement damage it over time. Watch for a wet patch that never dries, pressure that dropped throughout the house, or a bill that rose without a change in habits. Full Nelson locates the fault and completes water main line repair or replacement.
We offer:
- Water main line repair
- Water main line replacement
- Restoring water service
-
Sewer Line Repair and Replacement
When camera inspection shows collapsed sections, multiple root masses or a significant belly, spot repairs stop being economical. Full Nelson handles sewer line excavation and installs modern materials rated to serve the property for generations rather than patching a line that will fail again.
Our services include:
- Sewer line repair
- Sewer line replacement
- Video inspection
- Recommending a solution
-
Septic Tank Repair and Replacement
A large share of Smithville-area property sits outside municipal sewer service and depends on septic systems. Slow drains throughout the house, gurgling in the pipes, sewage odor in the yard and saturated ground over the tank all indicate a system needing attention. Systems on property near the lake deserve particular attention, because a failing system near surface water is a problem beyond the property line. Full Nelson inspects septic systems and completes the repairs needed to restore function.
Our services include:
- Septic tank repair
- Septic tank replacement
- System inspection
- Identifying issues
-
Septic Lateral Field Repair and Replacement
The lateral field disperses treated effluent into the surrounding soil for final filtration, and it depends on that soil accepting water at a workable rate. High seasonal groundwater near the river and the reservoir reduces the soil’s capacity to take effluent, which is why fields that worked for years can start surfacing after a wet spring. Full Nelson evaluates lateral field damage and performs repair or complete replacement.
Our services include:
- Septic lateral field repair
- Septic lateral field replacement
- System assessment
- Restoring proper drainage
-
Trenchless Sewer Repair and Replacement
On a long rural run, the length of a traditional trench is the cost. Trenchless methods limit excavation to access pits at each end of the damaged section, which matters more the further the line has to travel. Full Nelson evaluates whether trenchless work is viable on your property and explains where it is not.
Our services include:
- Trenchless sewer repair
- Trenchless sewer replacement
- Pipe bursting
- Pipe lining
- Installing new pipes
Fast & Reliable
Water Heater Services Smithville, MO
Hot water supports the whole household routine, and on a property with a well it depends on two systems working rather than one. Full Nelson provides water heater repair and installation for all system types with clear pricing before any work begins.
Gas Water Heater Repair and Replacement
Gas water heaters heat faster and cost less to operate than electric models. Pilot assemblies that will not stay lit, failed thermocouples and sediment accumulation that causes rumbling are the common failures, and sediment builds faster on water carrying more mineral content. Full Nelson services all major brands and installs replacement gas units sized to your household’s actual demand.

Electric Water Heater Repair and Replacement
Electric water heaters serve homes where natural gas does not extend, which describes a good deal of property outside Smithville proper. Heating elements burn out, thermostats fail, and tank interiors corrode until they leak. Scale from harder well water shortens element life noticeably. Full Nelson diagnoses the fault and advises whether repair or replacement is the better decision.
Tankless Water Heater Repair and Replacement
Tankless units heat on demand and remove the standby loss of keeping forty or fifty gallons hot around the clock. Where water carries meaningful hardness, and particularly on well water, tankless heat exchangers need descaling on a regular schedule to keep performing. Full Nelson services tankless systems from all manufacturers, installs new units, and will tell you plainly whether your water makes one a good idea.
Hybrid Water Heater Repair and Replacement
Hybrid water heaters use heat pump technology to pull warmth from surrounding air rather than generating it electrically, using far less energy than resistance elements. They need a space that stays above 40 degrees year-round with adequate air volume. On a property where electric resistance heating is the alternative, the operating cost difference is substantial. Full Nelson installs and services hybrid systems.
Stay Comfortable Year-Round
Heating Services
Smithville, MO
Smithville has a humid subtropical climate, but the record book tells you what it is capable of. The city has recorded a low of 26 degrees below zero twice, in December 1989 and again in February 2021, against a record high of 107 degrees in August 1988. That February 2021 figure is the one to keep in mind, because it is recent, and because a stretch of cold that deep is what freezes and splits supply lines in crawl spaces, exterior walls and unheated outbuildings.
Full Nelson acquired a 25-year Kansas City HVAC company in 2019, adding decades of heating experience to our plumbing foundation. Before a cold snap, the useful work is insulating vulnerable runs, checking that heat reaches the spaces where pipes live, and confirming the furnace will hold through a week of continuous operation rather than a normal winter night.

Furnace Repair, Installation, and Maintenance
Gas furnaces heat most homes in town, while outlying properties run propane or electric heat. Equipment that copes with an ordinary Missouri winter can still fail during an extended sub-zero stretch, because it runs continuously rather than cycling. Common failures include ignition system problems, blower motor burnout and cracked heat exchangers that allow combustion gases into living space. Full Nelson provides furnace repair for all makes and models and sizes replacement equipment for the conditions this area actually produces.
Our services include:
- Furnace repair & replacement
- Furnace installation
- Furnace maintenance
-
Heat Pump Repair, Installation, and Maintenance
Heat pumps move heat rather than generating it, delivering heating and cooling from one outdoor unit, and cold-climate models hold efficiency well below freezing. On a property without natural gas service, a heat pump replaces electric resistance heat at a fraction of the operating cost. Proper auxiliary heat sizing matters here given the recorded lows. Full Nelson provides heat pump service for all brands.
Our services include:
- Heat pump repair and replacement
- Heat pump installation
- Heat pump service
- Heating system maintenance
-
Filters, Humidifiers, UV Lights, and Indoor Air Quality
Heated winter air loses moisture rapidly, dropping indoor humidity to levels that cause static shocks, dry skin, irritated sinuses and damage to wood floors and furniture. During an extended cold stretch when the furnace runs almost continuously, that drying is far more pronounced than in an average winter. Full Nelson installs whole-home humidifiers, high-efficiency filters and UV light systems.
Our services include:
- Improving indoor air quality
- High-efficiency filters
- Humidifiers
- UV lights
- UV light installation in ductwork
Breathe Easier
Air Conditioning Services
Smithville, MO
Smithville’s humid subtropical climate has produced a recorded high of 107 degrees. Air conditioning here handles both heat and the moisture that comes with proximity to a 7,190-acre reservoir. Full Nelson provides air conditioning services throughout Smithville and the surrounding area.

Air Conditioning Repair, Replacement, and Maintenance
Refrigerant leaks cut capacity, dirty coils block heat transfer, and failing capacitors force compressors to work against themselves. Outdoor units on rural property take in far more airborne debris, cottonwood seed and grass clippings than units in a tight suburban yard, and a matted coil turns a maintenance item into a compressor failure. Full Nelson technicians diagnose accurately and complete AC repairs that restore cooling.
Our services include:
- Air Conditioning Repair & Replacement
- Air Conditioning Installation & Maintenance
- Refrigerant leaks
- Compressor problems
- Electrical failures
-
Mini Split Repair, Replacement, and Installation
Detached shops, barns, garages, guest quarters and bonus rooms are common on Smithville property, and none of them are on the main duct system. Mini splits condition those spaces individually and let you heat or cool a workshop only when you are in it, which is the practical way to make an outbuilding usable year round.
-
Filters, Dehumidifiers, UV Lights, and Indoor Air Quality
Living near a large body of water means living in higher summer humidity, and basements and lower levels hold that moisture longest. Whole-home dehumidifiers address it far more effectively than running the air conditioner harder. Combined with upgraded filtration and UV treatment, the difference is measurable, and on rural property where doors stand open and dust load is higher, filtration earns its cost quickly.
-
Duct Services
Gaps at duct connections and seams leak conditioned air into crawl spaces and attics, wasting energy and creating hot and cold rooms. In a home with ductwork running through an unconditioned crawl space, those same runs are also where pipes freeze during a deep cold snap, so sealing and insulating that space pays twice. Full Nelson provides duct cleaning and duct sealing.
- Power When You Need It
Generator Installation
Smithville, MO
Smithville is the furthest north community we serve and among the least densely built, which is the profile that produces the longest outages. Ice storms bring down lines running across open country and through tree cover, and crews covering a rural service area take longer to reach every customer. Two things make an outage here more serious than in the suburbs: properties on private wells lose water completely without power, and an extended winter outage in a region that has recorded 26 below zero puts the plumbing itself at risk.
A standby generator starts automatically within seconds and keeps the well pump, sump pump, furnace, refrigerator and lights running until crews restore service.
Whole-Home Standby Generators
- Whole-Home Standby Generators
- Automatic startup during power outages
- Keeps lights, HVAC, and appliances running
- Protects against storm-related outages
Full Nelson sizes generators to your home’s actual electrical load and handles the complete installation, including the automatic transfer switch and fuel connection.
For Local Businesses
Commercial Heating & Air Conditioning
Smithville, MO
Smithville’s commercial base centres on its downtown, where the Downtown Smithville Historic District is listed on the National Register, along with the businesses serving lake visitors and a growing residential population. Restaurants, retail and marina-area operations all run refrigeration and climate control where a failure in season costs real money. Older downtown buildings present the usual challenges of limited roof structure and mechanical systems adapted into a building rather than designed for it. Full Nelson provides commercial HVAC services and commercial plumbing.
