5 Reasons to Hire a Licensed Plumber

By Roman, Master Plumber · WA Lic# SASQUPL882BZ Published 9 min read

When plumbing issues strike, it’s tempting to fix them yourself. But hiring a licensed plumber is almost always the better choice. Here’s why:

  • Expert Training: Licensed plumbers undergo thousands of hours of hands-on training and education to handle complex repairs and installations safely.
  • Specialized Tools: They have access to advanced equipment like hydro jetters and video inspection systems, which aren’t available to most homeowners.
  • Code Compliance: Licensed plumbers ensure your plumbing meets local building codes and handle permits, avoiding fines or insurance issues.
  • Insurance Protection: Their insurance covers accidents and workmanship, protecting you from unexpected costs.
  • Warranties: They guarantee their work, so you’re not stuck paying for the same repair twice.

DIY plumbing can lead to bigger problems, void insurance, or even cause safety hazards. Licensed plumbers provide the skills, tools, and peace of mind needed for lasting solutions.

5 Key Benefits of Hiring a Licensed Plumber vs DIY

5 Key Benefits of Hiring a Licensed Plumber vs DIY

1. Professional Training and Certification

Licensed plumbers earn their credentials through a combination of extensive, hands-on training and classroom education, equipping them to handle everything from simple repairs to intricate installations. Depending on local regulations, becoming a journey-level plumber requires between 4,000 and 8,000 hours of supervised fieldwork, along with formal coursework. This demanding process ensures a solid foundation of expertise for any plumbing project.

The journey to licensure blends practical experience with theoretical knowledge. Classroom instruction typically covers plumbing principles, mathematics, blueprint interpretation, and local building codes. As Options Plumbing explains:

"To become a licensed plumber, you must have at least 4,000 hours (about 2 years) experience working under a licensed plumber. You also have to have 24 hours of classroom training and pass the state licensing exam."

This structured system creates a clear progression of skill levels: apprentices are beginners learning the trade under supervision, journeypersons have completed their training and can work independently, and master plumbers - who usually have 8 or more years of experience - are qualified to manage complex projects or run their own businesses. Such a hierarchy ensures that homeowners get the right expertise for their specific needs.

Licensed plumbers bring a level of precision and knowledge that online tutorials simply can't match. For instance, they understand the exact torque needed for pipe fittings or how to safely connect pipes made of different materials. Devynn Thompson, Co-Owner of Thompson Family Plumbing, highlights their expertise, noting that licensed plumbers excel in skilled handwork and problem-solving.

To maintain their credentials, plumbers often complete continuing education courses to stay updated on the latest technologies and changes to building codes. Many states also require background checks as part of the licensing and renewal process, offering homeowners an added layer of assurance. This commitment to ongoing improvement underscores the reliability and professionalism that licensed plumbers bring to every job, safeguarding both your home and your investment.

2. Access to Specialized Equipment and Tools

Licensed plumbers come equipped with advanced tools and machinery that you simply won’t find at your local hardware store. These are industrial-grade devices built to tackle problems that DIY fixes can't handle. For example, a SeeSnake camera system can set you back around $10,068, while a RIDGID K-J2200 hydro jetter costs about $6,696. These hefty price tags make such equipment impractical for the average homeowner.

What makes this equipment so valuable is its ability to deliver precise and efficient diagnostics. Take video camera inspection systems, for instance - they allow plumbers to see inside your pipes without tearing up floors or digging into your yard. Plumbing expert Chris Buckingham explains:

Professional plumbers utilize the latest in technology, including video camera inspections for sewer lines and other plumbing-specific tools that tend to be exclusively owned and operated by professional plumbers.

This kind of technology is a game-changer for identifying hidden problems like tree roots invading pipes, collapsed sections, or cracks that might otherwise require costly exploratory work.

When it comes to stubborn clogs, hydro jetting machines are in a league of their own. Unlike standard drain snakes, hydro jetters use high-pressure water to clean the entire diameter of a pipe. This process removes grease buildup, mineral deposits, and other debris, reducing the chances of recurring blockages.

Other specialized tools, like Milwaukee's press tool, speed up pipe connections by 40% compared to traditional manual methods. These systems also eliminate the need for open-flame soldering, making installations safer and faster. For gas line work, safety is paramount, and Peter deBaptiste emphasizes that only trained professionals should handle these high-risk tasks.

Beyond solving immediate problems, professional-grade tools can catch smaller issues before they escalate. For instance, a camera inspection can reveal whether a recurring drain issue is just a clog or a sign of a deeper structural problem. Companies like Sasquatch Plumbing Services Seattle rely on tools like hydro jetters and camera inspections to accurately diagnose and address issues, ensuring long-term solutions. This level of precision and expertise underscores the value of hiring a professional plumber.

3. Knowledge of Building Codes and Permit Requirements

Plumbing isn’t just about fixing leaks or laying pipes - it’s about doing it the right way, within the bounds of the law. In the U.S., 44 states require plumbers to hold a professional license for major tasks like installing new plumbing systems or tankless water heaters. This licensing ensures they’re well-versed in local building codes and permit requirements. Take Washington State, for example - earning a plumbing certification there involves extensive supervised work. This rigorous process ensures licensed plumbers know exactly which projects need permits and how to navigate the approval process with local inspectors. Their expertise doesn’t just keep projects up to code - it makes handling permits far less stressful.

When you hire a licensed plumber, they’ll take care of the entire permit process for you. In many places, including Washington, only licensed contractors or property owners can legally obtain plumbing permits. From filing paperwork to coordinating with the building department and scheduling inspections, your plumber manages it all, sparing you the hassle. As Stacey L. Nash, a contributing writer at Angi, puts it:

A licensed plumber will be familiar with codes, compliance rules, and the process to obtain permits.

Skipping permits or hiring unlicensed workers can lead to big problems. Many homeowners’ insurance policies won’t cover damages caused by unpermitted work. If something goes wrong - like a sewage backup or a fire from an improperly installed gas water heater - you could be stuck footing the bill for repairs. Worse, you might face fines or be forced to redo the entire job at your own expense.

Building codes are there for a reason: to protect you and your home. They help prevent dangers like carbon monoxide leaks from gas water heaters or toxic chemicals contaminating your drinking water. Licensed plumbers have the training to ensure everything is installed safely and correctly, reducing these risks.

Professionals - like those at Sasquatch Plumbing Services Seattle - have a deep understanding of safety standards and local regulations. They’ll ensure your home stays safe and fully compliant, giving you peace of mind.

4. Insurance Coverage and Liability Protection

Hiring a licensed plumber not only ensures skilled service but also shields you financially in case something goes wrong. Licensed plumbers carry insurance that protects homeowners during repairs or installations.

General liability insurance is a key safeguard. It covers accidental property damage caused by the plumber. For instance, if a plumber accidentally breaks a pipe and your kitchen floods, their insurance can cover the cost of repairing your flooring, cabinets, and walls. Without this protection, you could be left with repair bills that easily exceed $20,000.

On top of that, workers' compensation insurance is another layer of protection. If a plumber gets injured while working on your property, their medical expenses and lost wages are handled by their insurance. This prevents you from being held financially responsible for workplace injuries. Additionally, licensed plumbers are bonded, which protects you if the job is left incomplete or if any property goes missing.

Brent Thurman, Owner of Keystone Insurance, highlights an important risk:

"Some insurance policies have clauses that will invalidate your homeowners insurance coverage if work is performed by unlicensed individuals or businesses. This means that any claim on your home arising from the work of a non-licensed contractor may be denied."

These insurance measures, combined with the high standards licensed plumbers adhere to, offer an added layer of security for your home. Always ask for a copy of the plumber's insurance certificate and license, and verify their credentials. Licensed professionals, like those at Sasquatch Plumbing Services Seattle, carry the necessary insurance and bonding, ensuring you can feel confident throughout the repair or installation process.

5. Warranties and Guaranteed Repairs

Hiring a licensed plumber offers peace of mind with warranties that typically cover labor and materials for about a year. If something goes wrong during that time, they’ll fix the issue at no additional cost. This level of assurance is backed by industry professionals who emphasize the importance of guaranteed repairs.

Thomas Suchla, Owner of Southport Home Services, highlights this benefit:

"Licensed plumbers commonly offer a limited guarantee on workmanship for many repairs and installations, usually lasting about a year. If something goes wrong with how they installed it, they'll come back and make it right."

This guarantee saves you from repeated repair bills. Unlike DIY fixes or unlicensed work - which come with no such promise - licensed plumbers address the root of the problem instead of just masking the symptoms. This ensures the issue is resolved for good, preventing additional expenses or further damage.

Another crucial factor is preserving manufacturer warranties. Many appliances, like water heaters and dishwashers, require professional installation to keep their factory warranties valid. A DIY installation could void these protections, leaving you on the hook for the full cost of replacement if something goes wrong.

When you choose Sasquatch Plumbing Services Seattle, you’ll enjoy a workmanship guarantee that provides added confidence. Always request warranty terms in writing and keep all related documentation for future reference.

Conclusion

In short, hiring a professional plumber safeguards your home, wallet, and well-being. Plumbing problems can disrupt your daily life and potentially lead to costly damage if not handled correctly. Licensed plumbers undergo extensive training, hold state certifications, and have access to specialized tools unavailable to most DIY enthusiasts. They also ensure compliance with building codes and permit requirements - essential since most major plumbing projects legally require a professional license.

Additionally, their insurance and warranties provide a safety net against unexpected repair costs, making the decision to hire a licensed plumber a smart financial move. These advantages highlight why professional plumbing services are a practical and reliable choice.
