Raymore, MO
Family, Women & Veteran Owned • Serving the Kansas City Metro Since 2003
We Exceed Expectations
Full Nelson serves Raymore homeowners with plumbing, heating and air conditioning work built on clear explanations and technical skill. Raymore counted 22,941 residents in the 2020 census across 17.75 square miles of Cass County, and the census estimate for July 2024 put the figure at 25,306.
That growth is the fastest in the state. Between July 2022 and July 2023 Raymore was the fastest growing city in Missouri at 4.7 percent, ranking 66th fastest in the country. Most of the housing here is recent, which changes what breaks and when. Newer homes fail differently than older ones, and knowing the difference is the job. Learn more about our company.

Plumbing Services in Raymore, MO
Raymore was platted in 1872 and incorporated on 20 March 1877, taking its name from two railroad men, George Rea and Henry Moore. There is a genuine historic core here, including the Watkins Family Farm Historic District added to the National Register in 2007. But the overwhelming majority of Raymore homes went up during the growth of the last twenty-five years, and that creates a service profile most plumbers in this market are not set up to talk about.
New does not mean trouble-free. It means the trouble arrives on a different schedule. Builder-grade equipment is installed to code and to budget rather than to longevity, and the first wave of it reaches the end of its service life somewhere between years ten and fifteen. Cass County’s clay soils continue moving under recently laid lines for years after a subdivision is finished. Full Nelson’s licensed plumbers work on both the historic core and the new subdivisions.

Drain Cleaning
Drain problems in newer Raymore homes rarely come from deteriorated pipe. They come from installation and from ground movement. A sewer line laid at marginal slope will still pass inspection and still hold solids once the soil under it settles a fraction of an inch. That produces a house that backs up periodically from the day it was built rather than a house that developed a problem. Camera inspection tells you which one you have. 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
Clay-heavy Cass County soil expands when wet and contracts when dry, and in a subdivision built within the last two decades that soil has not finished settling around the pipe. The result is a belly in the line, a low spot that holds water and solids. Because the pipe itself is modern and undamaged, a homeowner is often told nothing is wrong. Video inspection shows the standing water clearly. Full Nelson runs the camera, shows you the footage, and explains your sewer repair options honestly, including when the answer is that the line is fine.
Our services include:
- Sewer line repair and installation
- Sewer video inspection
- Trenchless excavation using pipe bursting technology
-
Sump Pumps and Battery Backup Systems
New subdivisions are graded before the landscaping matures, and drainage patterns shift as yards establish, fences go in and neighbors regrade. Builder-installed sump pumps are typically the minimum unit that satisfies the requirement, with no backup. Full Nelson installs sump pumps and battery backup systems sized to the water your lot actually produces, and battery backup so the pump keeps running when the storm that fills the pit also takes the power out.
Our services include:
- Sump pumps
- Battery backup systems
-
Gas Leaks and Gas Repairs
Natural gas heats most Raymore homes and feeds water heaters, ranges, dryers and outdoor grills. In newer construction, leaks are more often found at connections made during the build or at later additions such as a gas line run to a patio kitchen or a fire pit. 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
Builder-grade toilets are chosen on price. Many perform adequately when new and then flush poorly as the rim jets scale over, and the internal parts are often the cheapest available. A running toilet adds hundreds of gallons to the monthly bill. Full Nelson diagnoses whether the fault is the fixture, the drain line or the vent, and completes repairs or installs a better-performing replacement.
Our services include:
- Toilet repairs & replacements
- Flapper replacements
- Toilet rebuilds
- Water-efficient toilets
-
Faucets and Shower Valves
Builder-grade faucets and shower valves use lighter internal components than the same manufacturer’s retail lines, and they wear faster. A shower valve that will not hold temperature in a ten-year-old house is usually a worn cartridge rather than a failed valve body, which makes it an inexpensive fix if diagnosed correctly. Full Nelson repairs faucets and shower valves from all major manufacturers and handles replacement when a fixture is genuinely spent.
Our services include:
- Kitchen faucets
- Bathroom faucets
- Shower valves
- Tub fixtures
-
Water Filtration
Raymore operates its own water distribution system serving roughly 8,627 residential and commercial customers, including the Kentucky Pump Station and two storage facilities. Treated municipal water still carries chlorine taste and picks up sediment moving through the distribution network, and a system expanding to keep pace with rapid growth sees more main work and more disturbance than a static one. Full Nelson tests your water and recommends filtration based on measured results.
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 efficiency and shortening equipment life. In a newer home that scale is quietly working on equipment still under a decade old. Full Nelson measures hardness at your address and sizes a softener to your household rather than installing a standard unit everywhere.
Our services include:
- Water softeners
- Water softener installation
- Water softener service
-
Well Pumps and Well Tanks
Properties on the rural edges of Raymore and out into Cass County draw water from private wells. When a submersible pump fails or a pressure tank bladder ruptures, the property loses water entirely. 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 Raymore, MO
Buried lines in Raymore’s newer subdivisions are modern materials in soil that is still moving. That combination produces a different excavation profile than an old neighborhood: less corroded pipe, more settlement damage and more disturbed backfill from the original construction. Full Nelson provides excavation services 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. In newer construction, failures usually trace to the installation or to ground movement rather than to age. 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 a belly holding standing water, a separated joint or crushed pipe from construction traffic, the repair is excavation to the affected section and correction of the bedding underneath. Simply replacing pipe without fixing what is under it produces the same problem again. Full Nelson handles sewer line excavation and corrects the underlying cause.
Our services include:
- Sewer line repair
- Sewer line replacement
- Video inspection
- Recommending a solution
-
Septic Tank Repair and Replacement
Properties outside the municipal sewer system rely on septic tanks to treat household wastewater. Slow drains throughout the house, gurgling in the pipes, sewage odor in the yard and saturated ground over the tank all point to a system needing attention. 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. Cass County’s clay soils drain slowly, which makes lateral field sizing and condition more critical here than on well-draining ground. When lines clog with biomat, crush under vehicle traffic or fail from age, sewage backs up into the house or surfaces in the yard. Full Nelson evaluates lateral field damage and performs repair or replacement.
Our services include:
- Septic lateral field repair
- Septic lateral field replacement
- System assessment
- Restoring proper drainage
-
Trenchless Sewer Repair and Replacement
Newer Raymore lots often have irrigation systems, recent hardscape and young trees that have finally established. A full trench takes all of it out. Trenchless methods confine excavation to access pits at each end of the damaged run. Full Nelson evaluates whether trenchless work suits your property and explains where it does not.
Our services include:
- Trenchless sewer repair
- Trenchless sewer replacement
- Pipe bursting
- Pipe lining
- Installing new pipes
Fast & Reliable
Water Heater Services Raymore, MO
This is where the age of Raymore’s housing matters most. Builders install water heaters that meet code at the lowest workable cost, and a tank installed when a subdivision went up in the 2000s or early 2010s is now at or past the point where tanks fail. A large share of Raymore homes reached that point at roughly the same time, because they were built at roughly the same time. Full Nelson provides water heater repair and installation and will tell you plainly whether yours is worth repairing.
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 in a tank that has never been flushed. Full Nelson services all major brands and installs replacement gas units sized to your household rather than to the builder’s minimum.

Electric Water Heater Repair and Replacement
Electric water heaters serve homes where gas is unavailable, including properties beyond the gas service area. Heating elements burn out, thermostats fail, and tank interiors corrode until they leak. 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. For a growing family in a home originally fitted with a minimum-spec tank, a tankless upgrade solves the capacity problem rather than repeating it. Heat exchangers need periodic descaling. Full Nelson services tankless systems from all manufacturers and installs new units.
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. Full Nelson installs and services hybrid systems and evaluates whether your utility space suits one.

Furnace Repair, Installation, and Maintenance
Furnaces in newer Raymore homes are usually the model that met the builder’s specification, and they are frequently paired with duct systems designed for the same standard. Where a homeowner has since finished a basement or added a bonus room, that original system is now serving more square footage than it was sized for, which shows up as long run times and rooms that never reach setpoint. Full Nelson provides furnace repair for all makes and models and looks at the whole system when replacement comes up.
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. Cold-climate models hold efficiency well below freezing, and they are worth serious consideration on properties without natural gas service. 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 cabinetry. Newer homes are built tighter than older ones, which helps with efficiency but makes mechanical ventilation and filtration more important rather than less. 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

Air Conditioning Services
Raymore, MO
Missouri summers combine heat and humidity that make air conditioning essential. Full Nelson provides air conditioning services throughout Raymore and Cass County.

Air Conditioning Repair, Replacement, and Maintenance
Air conditioners installed during Raymore’s build-out are reaching the age where compressors, capacitors and coils start failing, and many are still the original builder-specified equipment. Refrigerant leaks cut capacity, dirty coils block heat transfer, and failing capacitors force compressors to work against themselves. Full Nelson technicians diagnose accurately and complete AC repairs that fix the actual fault.
Our services include:
- Air Conditioning Repair & Replacement
- Air Conditioning Installation & Maintenance
- Refrigerant leaks
- Compressor problems
- Electrical failures
-
Mini Split Repair, Replacement, and Installation
Finished basements, bonus rooms over garages and sunroom additions are common in Raymore’s newer housing, and in most cases the original duct system was never extended properly to serve them. Mini splits condition those spaces directly without reworking the whole system, and they let you condition a room only when it is in use. Full Nelson installs mini splits and services existing systems.
-
Filters, Dehumidifiers, UV Lights, and Indoor Air Quality
Tighter new construction holds humidity as well as it holds conditioned air, and a finished basement in a humid Missouri summer is where that shows first. Whole-home dehumidifiers control it more effectively than running the air conditioner harder. Combined with upgraded filtration and UV treatment, the difference is measurable.
-
Duct Services
Duct systems in production-built homes are installed quickly, and gaps at connections and seams are common even in recent construction. That leakage wastes conditioned air into attics and crawl spaces and creates the hot and cold rooms homeowners describe. Full Nelson provides duct cleaning and duct sealing.
- Power When You Need It
Generator Installation
Raymore, MO
Raymore sits toward the southern edge of the metro where utility feeder lines run long distances across open country. Ice storms and summer straight-line winds bring them down, and restoration on the outskirts takes longer than in the dense suburbs. A standby generator starts automatically within seconds and keeps the refrigerator, HVAC system, sump pump 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.
