Drain Doctor’s technicians can perform all types of plumbing repairs.

Drain Doctor, Inc. provides a complete array of plumbing services and repairs for residential and commercial clients throughout the Greater Bay Area. The company has the in-house capabilities to handle specialty plumbing work such as trenchless sewer line replacements and tankless water heater installations, and it also offers 24/7 emergency services for its customers’ convenience.

General Manager John Lim says much of Drain Doctor’s success is due to its ability to handle large volumes of work without compromising its attentive approach to customer care. “We’re one of the largest plumbing companies in the Bay Area, but we’re still privately owned and operated, so taking care of our customers and community has always been very important to us.”

Drain Doctor prioritizes fast, reliable service in every aspect of its operations, which Mr. Lim says is crucial for ensuring high levels of customer satisfaction. “We try to get to every job within 45 minutes of the initial call, regardless of its size or if it was scheduled. Our clients know we’ll be available to help them whenever they have a plumbing problem, and they really appreciate that.”

“We combine superior service, expert knowledge and high-quality materials to provide effective solutions for all our customers’ plumbing needs. Our goal is to deliver products and services that exceed their expectations and reinforce our position as a leader in quality indoor comfort.”

If you need to re-pipe your home’s sewer system, make sure you choose the right material. Whether your home’s water pipes are corroded or your septic system is damaged, repairing and replacing pipes is sometimes a necessary action. As with most aspects of plumbing, you have options as to what kind of piping material you want for your system, though in some cases external factors may limit your choices.

For water pipes, it typically comes down to a choice between plastic and copper. Plastic piping comes in two forms: polyvinyl chloride (PVC), which is used for cold water supply, drain and vent pipes; and chlorinated polyvinyl chloride (CPVC), which is used for hot water supply pipes because of its heat-resistant properties. The principal benefit of plastic piping is its initial cost savings—because of their lightweight character, plastic pipes are inexpensive to transport and install.

Copper pipes are significantly more expensive than plastic pipes, but their durability is superior, they’re recyclable (which adds resale value to the home) and they can expand to accommodate frozen water during the winter. According to Chris Choi, HR manager at Drain Doctor, Inc. in Santa Clara, copper is the best option for a long-term investment. “Copper works great for water lines because it’s strong, safe and practically foolproof once it’s set up,” he says. “Plastic pipes have come a long way, but copper is still the best material to use for fresh water piping.”

With some types of piping, the material you choose may be predetermined by municipal ordinances or state building codes. Mr. Choi says this is often the case with sewer lines. “Some areas require cast-iron pipes, while others require plastic. Also, some cities don’t allow fusion plastic, which is what a lot of plumbing companies use for trenchless sewer lines.” If your local or state legislation limits your piping options, consult a plumbing contractor to determine the best available material for your specific project.

Maintaining customer satisfaction is a crucial aspect of any business, but it's even more important for plumbing companies that have earned the prestigious Diamond Certified award. For Drain Doctor, Inc., the key to achieving and maintaining high levels of customer satisfaction is simple: combine the resources of a large company with the personalized service of a small business. "We never forget that we're a local company, not a franchise of some corporate chain," says General Manager Samuel Lim. "Our Bay Area roots run deep, so serving our community is very important to us."

Drain Doctor has been providing plumbing services and repairs for residential and commercial clients throughout the Greater Bay Area since 1996. The company has the in-house capabilities to handle everything from general plumbing repairs to trenchless sewer line replacements and tankless water heater installations, and it strives to arrive at each job within 45 minutes of the initial call, regardless of its size or if it was scheduled.

Unlike plumbing companies whose lack of training and equipment forces them to limit the scope of their work, Drain Doctor utilizes its staff of industry specialists to provide a variety of services that fulfill all types of plumbing needs. "Our goal is to match the right technician to the right job every time," says Mr. Lim. "If a customer has a water heater problem, we'll send one of our water heater specialists. If it's a drain problem, we'll send a drain specialist. That way, our customers can count on receiving the highest quality services no matter what."

Another distinguishing feature of Drain Doctor is its ability to offer 24/7 emergency services, which Mr. Lim says is important for making the plumbing repair process as convenient as possible for customers. "We want our customers to know that they can call us any time, even it's on a holiday or in the middle of the night. We're here to help them whenever they have plumbing problems."

They were very responsive. We had a toilet problem. The city came out at the same time as the plumber. He was very upfront with me about the fact that he was going to charge to get the job done right away, while the city would do it for free with a delay in service. We paid to have him do the job. It was a good experience.

The responsiveness, my expectation when I call is that they are going to come out right away. They did. Everyone is always very pleasant that we only have one bathroom and need it done quickly. We have used them several times and will continue to use them.

The project didn't require any digging of trenches. Normally, a sewer problem requires digging a trench. In my case that wasn't possible because the line went under a tree.
