How much does it cost to hire a plumber?

Plumbing service calls typically range from $89–$150 for a service fee, with most common repairs falling between $150–$750, depending on complexity and parts required. Larger repairs like slab leaks or sewer line replacements can range from $2,000–$10,000+.

 

Pricing depends on access, materials, code requirements, and repair scope.

 

Do I have a slab leak?

Common slab leak signs include unexplained high water bills, warm spots on the floor, foundation cracks, or the sound of running water when fixtures are off. Slab leak detection usually costs $250–$750.

​

Accurate diagnosis requires professional electronic leak detection equipment.

​

Why is my water pressure suddenly low?

Low water pressure can be caused by a clogged aerator, a partially closed shut-off valve, a bad PRV valve, pipe corrosion, or a hidden leak. Our Liberty Hill licensed plumbers from On-Call Plumbing can diagnose the issue and restore your water flow quickly.

 

What causes my drains to keep clogging?
Frequent clogs may be due to grease, hair, soap scum, or even tree roots in your sewer line. Our team at On-Call Plumbing can perform a thorough drain cleaning or camera inspection to identify the source.

​

How do I know if I have a water leak behind the wall?
Signs include water stains, mold, musty smells, peeling paint, or an increase in your water bill. Our licensed plumbers from On-Call Plumbing use advanced leak detection tools to pinpoint hidden leaks with minimal disruption.

​

Why does my toilet keep running after I flush it?
This is often caused by a faulty flapper, misadjusted float, or worn fill valve. On-Call Plumbing can quickly repair or replace the necessary parts to stop the waste of water.

​

Is it normal to hear banging noises in the pipes?
No, that “water hammer” sound can damage your plumbing over time. Our plumbers at On-Call Plumbing can install air chambers or arrestors to quiet your pipes and protect your system.

​

Why do I smell a sewer odor in my bathroom?
This could be due to a dry P-trap, clogged vent pipe, or damaged sewer line. On-Call Plumbing can investigate the source and provide the right fix.

​

How can I tell if my water heater is going bad?
Look for signs like inconsistent water temperature, rust-colored water, unusual noises, or leaks. Our On-Call Plumbing team can inspect your unit and advise on repair or replacement.

​

What’s the difference between hard water and soft water?
Hard water contains minerals that can cause buildup in pipes and appliances. Our licensed plumbers at On-Call Plumbing can test your water and install a softener if needed.

​

Why is there water pooling around my water heater?
It could be a leaking tank, faulty pressure valve, or loose connection. On-Call Plumbing can assess the issue and help you avoid water damage.

​

Why is my water heater not producing hot water?

If your water heater isn’t producing hot water, the most common causes are a failed heating element, tripped breaker, bad thermostat, or a pilot light issue. Repairs typically cost $150–$600, while replacement ranges from $1,200–$3,500 depending on type.

​

Tankless systems may have sensor or descaling issues.

​

How long does a water heater last?

Traditional tank water heaters last 8–12 years, while tankless systems can last 15–20 years with proper maintenance. Annual flushing significantly extends lifespan.

Hard water areas may reduce longevity without maintenance.

 

Why is my water bill suddenly higher?

Sudden increases often indicate hidden leaks, running toilets, irrigation issues, or slab leaks. A toilet leak alone can waste up to 200 gallons per day.

A professional pressure or static test confirms whether the system is holding properly.

 

Can I use chemical drain cleaners?

Chemical drain cleaners are not recommended because they can damage pipes, void warranties, and create hazardous conditions. Professional drain cleaning using augers or hydro jetting is safer and more effective.

​

Repeated clogs usually signal a deeper issue.

 

What causes low water pressure in my house?

Low water pressure is often caused by leaks, failing pressure regulators, clogged aerators, or aging galvanized pipes. Pressure regulator replacement typically costs $350–$800.

Testing determines whether the issue is isolated or system-wide.

 

How do I know if my sewer line is clogged?

Warning signs include multiple drains backing up, sewage odors, or gurgling toilets. Sewer camera inspections typically cost $250–$500.

​

Tree roots are a common cause in residential properties.

 

Should I repair or replace my old pipes?

If your home has polybutylene or galvanized piping, replacement may be more cost-effective long-term. Whole-home repipes typically range from $6,000–$20,000 depending on home size.

​

Frequent leaks are a strong indicator replacement is warranted.

 

How often should I flush my water heater?

Water heaters should be flushed once per year, especially in hard water regions. Neglecting maintenance reduces efficiency and can void manufacturer warranties.

​

Sediment buildup is the leading cause of premature failure.

 

Do you charge a service fee?

Yes, we charge a diagnostic/service fee, typically $89–$150, which may be applied toward repair if approved.

​

This ensures proper evaluation before conclusions are made.

 

Are your Texas plumbers licensed and insured?

Yes, we are state licensed, insured, and background-checked. 

 

Do you offer emergency plumbing services?

Yes, we offer weekend emergency plumbing services, particularly for burst pipes, sewer backups, and slab leaks.

​

After-hours pricing may differ from standard rates.

 

Do you provide warranties?

Most reputable plumbers offer a 1-year labor warranty, while materials carry manufacturer warranties.

​

Warranty terms should be clearly documented in writing.

 

How long does a typical plumbing repair take?

Minor repairs (faucets, disposals, valves) often take 1–2 hours. Larger jobs like sewer repairs or slab leaks can take 1–5 days depending on access and permitting.

​

Can tree roots really damage my plumbing system?
Yes, they can infiltrate your sewer line and cause blockages or breakage. Our team at On-Call Plumbing can perform a camera inspection to check for root intrusion and recommend a long-term fix.
