Conroe Water Well Service provides water well drilling, pump repair, and system maintenance for homes and businesses throughout Conroe and Montgomery County, Texas. Whether your well has stopped producing, your pressure tank is failing, or you need a new well drilled on your property, we handle the work from start to finish.
Private wells serve thousands of households across this part of Texas, and they need attention that municipal systems never require. Pumps wear out, pressure switches fail, water quality shifts, and casings age. When something goes wrong, you lose water to your kitchen, your bathrooms, and your livestock.
We work on wells across Conroe, Willis, Montgomery, and the surrounding areas, and we know how the local aquifers and soil conditions affect what your system needs. On the pages ahead, you'll find details on our drilling services, pump replacement, water treatment options, and how to recognize the early signs that your well needs service.
Get the numbers you need to plan with confidence—no pressure, just clear and honest pricing.
We handle every stage of a private water system in Montgomery County, from drilling a new well on raw acreage to swapping out a failed pressure switch. Our licensed technicians service submersible and jet pump systems, bladder tanks, and wells ranging from shallow sand points to deep completions several hundred feet into the Gulf Coast aquifer.

Most service calls start the same way: no water at the tap, or water that sputters and runs dirty.
We diagnose the actual cause rather than replacing parts on guesswork. Common issues we correct include:
We pull the pump when needed, inspect the casing, and test amperage, voltage, and static and pumping water levels before recommending repairs.

New well construction in the Conroe area typically means drilling into the Chicot, Evangeline, or Jasper aquifer, with depth determined by your location and the yield you need.
We locate the borehole with attention to setbacks from septic systems, property lines, and structures, then set PVC or steel casing, install screen at the producing zone, and place a gravel pack and sanitary surface seal.
After development, the well is disinfected and test-pumped to establish sustainable yield.
Every installation is completed to Texas Department of Licensing and Regulation standards, and we file the required well report with the Texas Water Development Board.
We drill for homes, ranches, irrigation, and light commercial use, and we can size the well around future demand if you plan to add livestock, a pool, or acreage under irrigation.

Submersible pumps in this region usually last 8 to 15 years, depending on water quality, cycling frequency, and how well the motor was sized to the well. Signs a pump is failing:
Symptom | Likely Cause
|
|---|---|
Pump runs constantly
| Worn impellers, leak in drop pipe |
Short, rapid cycling
| Failed tank bladder, oversized pump |
Breaker trips repeatedly
| Motor short, damaged drop cable |
Internal storage | Clogged screen, dropping water table |

The pressure tank stores water under air pressure so the pump isn't forced to start every time someone opens a faucet.
When the internal bladder fails, the pump cycles on and off in short bursts. That cycling burns out motors and control components faster than anything else in the system.
We check air charge against the cut-in pressure, test for water in the air side, and inspect the tank shell for corrosion.
Replacement tanks are sized to the pump's flow rate and desired run time — generally, we look for at least one minute of continuous run per cycle. We also service and replace pressure switches, gauges, check valves, and relief valves during the same visit.
A private well is a small water system with mechanical, electrical, and sanitary components that all need periodic attention. We inspect, service, test, and treat wells throughout Conroe and Montgomery County so problems are caught before they interrupt your supply.

Our inspections cover the full system, not just the visible equipment. We check the well cap and sanitary seal, casing condition, wiring and control box, pressure tank pre-charge, pressure switch settings, check valves, and the pitless adapter or well head fittings.
We also measure static and pumping water levels, draw down the well to gauge recovery rate, and record amp draw on the pump motor.
Common findings include:
We provide a written summary with measurements, so you know the condition of the well before buying a property or scheduling repairs.

Routine service extends pump life and protects water quality. We recommend an annual visit for most residential wells, with more frequent checks on high-demand systems, irrigation wells, and commercial installations.
A maintenance visit typically includes:
Task | Purpose
|
|---|---|
Pressure tank charge check
| Prevents short cycling and premature pump failure |
Pressure switch adjustment
| Maintains consistent household water pressure |
Well cap and seal inspection | Blocks insects, debris, and surface runoff |
Motor amp and voltage readings | Detects wear before the pump fails |
Sediment and screen cleaning
| Restores flow rate |
We also perform well disinfection with chlorine when bacteria are present, after repairs, or when a well has been out of service.

Testing tells you what is actually in your water. We collect samples and coordinate laboratory analysis for the contaminants that matter most in this part of Texas.
Standard panels cover:
We suggest bacterial testing yearly and a broader chemical panel every three years, or any time you notice a change in taste, color, odor, or clarity.

Treatment should be matched to the test results, not guessed at. Once we know your water chemistry, we size and install equipment that addresses the specific issue.
Options we install and service include:
We also maintain existing systems — replacing filter media, rebedding tanks, checking backwash cycles, and verifying that treated water meets the standards it was installed to reach.
Beyond household wells, we drill dedicated irrigation supplies, plug wells that have reached the end of their service life, install constant-pressure equipment, and maintain systems for businesses across Montgomery County. Each of these jobs carries its own permitting, sizing, and equipment requirements.
An irrigation well is sized around gallons per minute, not household demand. We calculate your requirement based on acreage, zone count, sprinkler head type, and how many zones run at once.
Most residential landscape systems in the Conroe area need 20–40 GPM, while pasture and hay operations often need more.
Our irrigation drilling work includes:
We separate irrigation wells from potable supply lines and install backflow prevention where the two systems interact.
An unused well is a direct pathway from the surface into the aquifer. Texas requires that abandoned and deteriorated wells be capped or plugged, and the landowner is responsible for it.
We handle plugging in accordance with Texas Department of Licensing and Regulation rules and Lone Star Groundwater Conservation District requirements.
Our process:
This matters most on properties being subdivided, sold, or converted to a public water supply, where an open well can hold up a closing or trigger a violation notice.
Standard well systems cycle between a cut-in and cut-out pressure, so flow drops when a second fixture opens. A constant-pressure system uses a variable frequency drive to adjust motor speed and hold pressure steady.
System Type
| Pressure Behavior
| Best Fit
|
|---|---|---|
Conventional pressure tank
| Fluctuates 40–60 PSI | Single-story, modest demand |
Constant pressure (VFD)
| Holds within ~2 PSI | Two-story homes, multiple bathrooms |
Booster pump
| Adds pressure downstream | Long runs, elevation gain, storage tanks |
We size drives to the existing motor and confirm the well can sustain the demand before installation. A VFD also reduces motor start cycles, which is the main cause of premature pump failure.
Booster pumps make sense when a well produces adequate volume but the delivery point sits uphill or far from the wellhead.
Commercial wells serve RV parks, subdivisions, car washes, greenhouses, poultry and cattle operations, and light industrial sites around Conroe and Willis. These systems typically run larger pumps, hydropneumatic or ground storage tanks, and control panels with alternating lead-lag operation.
We service and install:
We also coordinate with TCEQ requirements for public water systems, including sanitary control easements and well completion documentation.
Downtime costs money on a commercial site, so we stock common motor and control components and can schedule service outside operating hours when the system cannot be taken offline during business use.
We hold Texas licensing for well drilling and pump installation, and we work daily across Montgomery County's Catahoula, Evangeline, and Jasper aquifers. Our crews follow a documented service process and install components rated for the mineral content and pressure demands common in Conroe soils.
Every job starts with a diagnostic visit. We measure static water level, check amp draw on the pump motor, test the pressure switch and tank precharge, and inspect the wellhead seal for contamination risk.
From there, we give you a written scope with parts and labor listed separately. No work begins until you approve the price.
For repairs, most pump pulls and replacements finish within a single day. New well installations follow a longer sequence:
We file the State of Texas Well Report with the TDLR after completion and leave you a copy.

We stock parts that hold up in East Texas groundwater, which often carries iron and hydrogen sulfide.

Related work we handle:
Most residential water well projects in Conroe move from first phone call to working faucet in one to three weeks, depending on permitting, equipment scheduling, and whether we are drilling new or servicing an existing system. Below we break down the stages, the site evaluation, and the material decisions that shape both cost and completion date.
Timelines vary by scope. A pump replacement often finishes in a single day, while a new well from scratch takes longer because of registration and equipment staging.
Stage
| Typical Duration
|
|---|---|
Initial consultation and site visit | 1–2 days from your call |
Lone Star Groundwater Conservation District registration | 3–10 business days |
Drilling (150–400 ft into the Gulf Coast Aquifer) | 1–2 days |
Casing, grouting, and development
| 1 day |
Pump, pressure tank, and wiring installation
| 1 day |
Water sampling and final testing | 3–5 days for lab results |
Emergency repairs — no water, tripped breakers, air spitting from taps — are scheduled ahead of planned work, usually same or next day.
Weather matters. Heavy rain in Montgomery County can delay rig access on soft ground, and we will tell you upfront if that is likely.
You receive documentation at closeout, including the state well report filed with the Texas Department of Licensing and Regulation.
Our evaluation starts with location. Texas rules require minimum separation from septic tanks, drain fields, and livestock areas, so we mark a compliant spot before any equipment arrives.
We then review:
What we need from you is straightforward: clear vehicles and stored items from the work zone, keep pets indoors, and confirm gate codes or lock combinations.
Design decisions follow the numbers. We calculate peak household demand — fixture count, irrigation, livestock — and size the system to meet it without short-cycling the pump.
Key specifications we settle before work starts:
Constant-pressure variable-speed pumps cost more upfront but hold steady pressure during simultaneous use — worth discussing if you irrigate.
We put every specification in writing so there are no substitutions on install day.
Water well projects in Conroe typically range from $3,750 for a shallow replacement well to $20,000 or more for a complete well and septic system. Depth, casing material, pump horsepower, and water treatment needs drive most of the difference between one quote and the next.
Depth is the single largest cost factor. Most Conroe-area wells reach the Gulf Coast Aquifer between 150 and 400 feet, and drilling is generally priced per foot.
Beyond depth, these variables move the final number:
We provide itemized estimates so you can see exactly where the money goes.
Casing material. PVC casing is standard for most Conroe residential wells and costs less than steel. Steel casing runs higher but holds up better in unstable formations or deeper installations.
Drilling method. Rotary mud drilling handles the sand and clay layers around Montgomery County efficiently and is the common choice. Air rotary is used less often locally and typically costs more.
Pump type. A 1/2 HP submersible pump serves a modest household; a 1 or 1.5 HP unit for a larger home or irrigation adds roughly $400 to $1,000. Constant-pressure systems cost more upfront but deliver steadier flow.
Service level. Repairing a single component is far cheaper than replacing an aging system, though a pump past 12 to 15 years often makes full replacement the better value.
The drilling quote rarely covers everything. Plan for these line items:
We flag these possibilities during the site visit so your budget reflects the full project, not just the borehole.
Below are typical 2026 ranges for the Conroe area:
Service | Typical Cost Range |
|---|---|
New residential water well (complete)
| $9,000 – $15,300 |

| $200 – $500 |
Water testing (bacteria, nitrates, minerals)
| $75 – $350 |
Well cleaning and redevelopment
| $500 – $2,000 |
Emergency and after-hours calls carry a higher service rate. We confirm pricing before any work begins.
Our service area extends well beyond Conroe city limits. We travel throughout Montgomery County and into neighboring counties to drill, service, and repair water wells for homes, farms, and commercial properties.
We also work around Lake Conroe, where shoreline properties and rural subdivisions often rely entirely on private wells for their water supply.
If your property sits outside the list above, it's still worth a call. We frequently take jobs in San Jacinto, Grimes, Waller, and Liberty counties, and we'll tell you upfront whether your location falls within our range.
Travel distance may affect scheduling and service rates on longer trips. We'll go over any additional costs before we dispatch a crew, so there are no surprises when the invoice arrives.
Rural addresses are our specialty. Many of the properties we visit sit at the end of long gravel drives with limited access, and our equipment is set up to handle those conditions.
Groundwater in this region varies from one area to the next. Depth to water, sand production, and iron content all shift depending on where you are in the county, and we adjust our recommendations accordingly.
