What's Included

Our Process

Diagnosis

We assess the location, severity, and likely cause of the clog before recommending a method, saving you money by using the right tool for the job.

Drain Clearing

We use cable augers, drain snakes, or hydro-jetting depending on the clog type and pipe condition to fully clear the blockage.

Camera Inspection (if needed)

For recurring clogs or main line issues, we run a camera through the line to identify root intrusion, pipe damage, or buildup that causes repeat problems.

Prevention Advice

We explain what caused the clog and give you practical advice on preventing it from recurring, no upselling, just honest guidance.

Understanding Drain Problems in the Highland Lakes

The Highland Lakes region presents a unique combination of factors that make drain problems more common and more challenging than in many other parts of Texas. Understanding these factors helps homeowners make informed decisions about drain maintenance and repair.

Hard water is the dominant factor. The water in Marble Falls, Kingsland, Burnet, and surrounding communities is among the hardest in Texas, with mineral content typically ranging from 300 to 400 parts per million, well above the 180 ppm threshold that water quality experts classify as “very hard.” This mineral-rich water leaves deposits of calcium carbonate and magnesium on every surface it contacts, including the interior walls of drain pipes. Over years and decades, these deposits accumulate and narrow the effective diameter of the pipe, slowing drainage and creating rough surfaces that catch grease, hair, soap scum, and other debris.

The aging pipe infrastructure in many Highland Lakes homes compounds the problem. A significant portion of homes in Marble Falls, Kingsland, and Burnet were built in the 1970s and 1980s, when cast iron and galvanized steel drain pipes were standard. These materials corrode from the inside over time, creating rough, pitted surfaces that accumulate deposits and debris far more readily than modern PVC pipe. Homes with original cast iron or galvanized drain lines are more prone to recurring clogs than homes with newer PVC plumbing.

The native vegetation of the Highland Lakes also contributes to drain problems. Cedar, live oak, pecan, and other native trees and shrubs have aggressive root systems that seek out moisture wherever they can find it. The small amount of moisture that escapes from aging sewer pipe joints is enough to attract roots, which grow into the pipe and eventually cause complete blockages. Root intrusion is one of the most common causes of recurring main line clogs in older Highland Lakes homes, and it is a problem that chemical treatments cannot solve, only mechanical removal and, in severe cases, pipe replacement will address it permanently.

Kitchen Drain Problems: Grease, Scale, and Food Waste

Kitchen drains are the most common source of drain calls in Highland Lakes homes. The combination of cooking grease, food particles, and hard water mineral scale creates a particularly stubborn form of buildup that accumulates in kitchen drain lines over time.

Grease is the primary culprit. When hot cooking grease is poured down the drain, it is liquid and flows easily. But as it cools in the drain pipe, it solidifies and adheres to the pipe walls. Over time, layer upon layer of solidified grease accumulates, narrowing the pipe and eventually causing complete blockages. This process is accelerated by the hard water mineral scale that provides a rough surface for the grease to adhere to.

Food waste from garbage disposals contributes to the problem. While disposals grind food waste into small particles, those particles still need to be flushed through the drain system. Starchy foods like pasta and rice swell when they absorb water and can form a paste-like substance that adheres to the pipe walls. Coffee grounds and eggshells are particularly problematic because they do not break down and accumulate in the trap and drain line.

The solution for kitchen drain buildup is professional drain cleaning, either cable auger treatment for moderate clogs or hydro-jetting for severe buildup. We can clear years of accumulated grease and scale from kitchen drain lines and restore full flow capacity. We also provide practical advice on preventing future buildup, including proper grease disposal practices and the use of enzyme-based drain treatments that break down organic matter before it can accumulate.

Bathroom Drain Clogs: Hair, Soap, and Mineral Scale

Bathroom drains, sinks, tubs, and showers, clog primarily from the combination of hair, soap scum, and mineral scale. Hair is the most immediate cause: it accumulates in the drain trap and on any rough surfaces in the drain pipe, forming a net that catches soap scum and debris. In hard water areas like the Highland Lakes, soap scum is particularly problematic because the minerals in the water react with soap to form a sticky, insoluble residue that binds hair and other debris into a dense mass.

Most bathroom drain clogs can be cleared with a cable auger or drain snake that physically breaks up and removes the hair-and-soap mass from the trap and upper drain pipe. For more severe clogs or recurring problems, we may recommend hydro-jetting to scour the pipe walls clean and remove the mineral scale that provides the rough surface for future buildup.

Toilet clogs are a separate category. Most toilet clogs are caused by flushing items that should not be flushed, “flushable” wipes (which are not actually flushable), paper towels, feminine hygiene products, and similar items. These materials do not break down in water the way toilet paper does and accumulate in the drain line. We clear toilet clogs with a closet auger designed specifically for toilet drain geometry, and we can address more severe blockages in the drain line beyond the toilet.

Main Sewer Line Cleaning and Hydro-Jetting

The main sewer line, the pipe that carries all wastewater from your home to the municipal sewer or septic system, is the most critical drain line in your home. A blockage in the main line affects every fixture in the house simultaneously and can cause sewage to back up into the lowest fixtures in the home if left unaddressed.

Main line clogs in Highland Lakes homes are most commonly caused by root intrusion, grease accumulation, and, in older homes, pipe deterioration that creates rough surfaces and partial collapses that catch debris. We address main line clogs with cable auger treatment for minor blockages and hydro-jetting for severe or recurring problems.

Hydro-jetting is the gold standard for main sewer line cleaning. A hydro-jetting machine pumps water at pressures of 3,000 to 4,000 PSI through a specialized nozzle that simultaneously scours the pipe walls and propels the debris downstream. Unlike cable auger treatment, which punches a hole through the clog, hydro-jetting removes the entire buildup from the pipe walls, restoring the full interior diameter of the pipe and leaving it as clean as when it was installed. For homes with a history of recurring main line clogs, hydro-jetting provides a more durable solution than repeated cable auger treatments.

Before hydro-jetting, we recommend a sewer camera inspection to assess the condition of the pipe. Hydro-jetting is highly effective on intact pipe, but it can damage pipe that is already cracked, corroded, or partially collapsed. The camera inspection tells us the condition of the pipe so we can recommend the right treatment, and it may reveal problems like root intrusion or pipe damage that need to be addressed as part of the repair.

Sewer Camera Inspection: See What Is Inside Your Pipes

A sewer camera inspection involves running a waterproof camera on a flexible cable through your drain lines to get a real-time view of the interior of the pipe. This technology has transformed drain and sewer diagnosis, instead of guessing at the cause of a recurring clog or a slow drain, we can see exactly what is happening inside the pipe and recommend the most appropriate treatment.

Camera inspection is particularly valuable for diagnosing recurring clogs that do not respond to standard treatments, for assessing the condition of older drain lines before a major repair or home purchase, and for locating the exact position of root intrusion or pipe damage. The camera records the inspection, so you can see exactly what we found and understand the basis for our recommendations.

In the Highland Lakes, we recommend camera inspection for any home with cast iron or galvanized steel drain lines that are more than 30 years old, for any home with a history of recurring main line clogs, and for any home where the sewer line runs through an area with large trees. The inspection takes 1-2 hours and provides a complete picture of the condition of your drain system.

Preventive Drain Maintenance for Highland Lakes Homeowners

The best drain clog is the one that never happens. A few simple practices can reduce the frequency of drain problems in Highland Lakes homes:

Never pour grease down the drain. Collect cooking grease in a container and dispose of it in the trash. Even small amounts of grease accumulate over time and create stubborn blockages.

Use a hair catcher in shower and tub drains. These inexpensive devices catch hair before it enters the drain and can be cleaned out regularly. They are the single most effective preventive measure for bathroom drain clogs.

Run hot water after each use of the kitchen sink. Hot water helps flush grease and food particles through the drain before they can accumulate.

Avoid flushing anything other than toilet paper. “Flushable” wipes, paper towels, and other products do not break down in drain lines and are a leading cause of toilet and main line clogs.

Consider enzyme-based drain treatments. Monthly use of enzyme-based drain treatments, available at hardware stores, introduces bacteria that break down organic matter in drain lines before it can accumulate into a clog. These are safe for all pipe types and septic systems.

Schedule professional drain cleaning every 1-2 years. Professional cleaning removes the mineral scale and organic buildup that accumulates even with good drain habits, keeping your drain system flowing freely and preventing the major clogs that require emergency service.

Frequently Asked Questions

Why do drains clog so often in Highland Lakes homes?

The extremely hard water in the Highland Lakes, typically 300-400 ppm, leaves mineral deposits inside drain pipes over time. These deposits narrow the pipe interior and create rough surfaces that catch grease, hair, and debris. Combined with the aging pipe infrastructure in many homes built in the 1970s and 1980s, this makes drain clogs more frequent here than in areas with softer water.

Can I use chemical drain cleaners instead of calling a plumber?

Chemical drain cleaners can clear minor clogs in plastic pipes, but they are not effective against grease buildup, mineral scale, or root intrusion. More importantly, they can damage older metal pipes and rubber gaskets, and they are hazardous to handle. For any clog that does not clear with a plunger, professional drain cleaning is safer and more effective than chemical treatments.

How do I know if my main sewer line is clogged?

Signs of a main sewer line clog include multiple fixtures draining slowly at the same time, gurgling sounds from drains when other fixtures are used, sewage backing up into floor drains or the lowest fixtures in the house, and foul odors from drains. If you notice any of these signs, call us immediately, a main line clog can cause sewage backup into your home if left unaddressed.

Do you service septic systems?

We service the drain lines that connect to septic systems, including clearing blockages between the house and the septic tank. For septic tank pumping and maintenance, we can refer you to a qualified septic service provider in the Highland Lakes area.

How often should I have my drains professionally cleaned?

For most homes, professional drain cleaning every 1-2 years is sufficient to prevent buildup and keep drains flowing freely. Homes with older pipes, hard water, or a history of frequent clogs may benefit from annual cleaning. Restaurants and commercial kitchens typically need quarterly or monthly service due to the volume of grease they produce.

What causes tree roots in sewer lines?

Tree roots naturally seek out moisture and nutrients, and the small amount of moisture that escapes from sewer pipe joints is enough to attract roots. Once a root finds a joint or crack in a sewer line, it grows into the pipe and eventually fills it completely. Cedar, oak, and pecan trees, all common in the Highland Lakes, are particularly aggressive root growers. Root intrusion is one of the most common causes of recurring main line clogs in older Highland Lakes homes.

How much does drain cleaning cost in Marble Falls?

Drain cleaning costs vary depending on the location and severity of the clog. A simple bathroom drain clearing is less expensive than a main line hydro-jetting job. Call us at (325) 248-1800 for honest pricing before we begin any work.
