Drain Cleaning & Unclogging
Bay Area's #1 Choice

Have you ever thought what system in your house is the most important? Internet or power? And what would you do if you can’t wash out waste and your sewage is clogged? A clogged drain can quickly turn into a biggest problem in a house. In the worst case scenario it could lead to water damage and a sewage backup.

United HVAC, plumbing and electrical has a professional drain cleaning team dedicated to unclogging only. United provides drain unclogging services throughout the Bay Area from Southern San Francisco up to Milpitas and from San Jose to Belmont. Whether you have a slow kitchen sink in Santa Clara, a backed-up shower, a toilet that will not flush, or a main sewer line that is starting to overflow, our team can diagnose the problem and clear the line with the right equipment.

What Causes Drain Clogs and When to Call a Professional?

Most drain clogs happen because material collects inside the pipe over time. It could be grease, oil, food scraps, coffee grounds, and soap residue. All this could gradually narrow the opening inside the pipe.

Bathroom drains usually clog from hair, toothpaste, shaving cream, soap scum, and small items. Toilets often back up because of wipes, paper towels, cotton pads, or too much toilet paper. Sometimes we find toys or tools that stops wastes movement in the sewer pipe.   Flushable products may pass through the toilet, but they often do not break down fast enough inside residential sewer lines.

Bay Area homes also have their own plumbing challenges. Our older homes specifically in downtown San Jose or in Palo Alto may have cast iron, clay, or galvanized pipes with rough interior surfaces. Our cities are close to mountains therefore hard water leaves mineral scale. Mature trees can send roots into small cracks or joints in sewer lines.

 Signs Your Drain Needs Professional Cleaning

A single slow drain may be caused by a spot blockage near the fixture. If two or more drains are slow at the same time, the problem could be in the main sewer line. If you hear gurgling toilets, if water is backing up into a shower or you feel sewer smell near sinks and bathrooms it could show that you have clog.

Chemical drain cleaners may seem like a quick fix, but they usually do not remove the blockage. We don’t use them. They can also be harsh on older pipes and dangerous for technicians if the line will be opened later. If the same drain slows down again after a few days or weeks, it is time to have the line professionally cleaned.

Professional Drain Cleaning Services: What the Job Involves

If you call us or set up appointment on the web site or Google page we can set an appointment with our technician. We train our call center agents and dispatchers to ask questions and asses the basics of the problem.

When a technician from United HVAC, plumbing and electrical arrives, his first step is to understand the symptoms and where did the problem happen. We check which fixtures are affected, ask questions: when the problem started, and whether this has happened before. Then we check access points, cleanouts, fixture drains, and visible plumbing conditions.

For many clogs, drain snaking is the best first step. A professional drain snake uses a flexible cable with a head designed to break through or pull out the obstruction. Snaking is commonly used for bathroom sinks, tubs, showers, toilets, laundry drains, and kitchen lines. Snaking tools are very different: from auger to cleanup local clog in the toilet to a huge 4K drain cleaning machine.

Hydro-jetting is used when the pipe has heavy buildup along the walls. This method sends high-pressure water through the line to wash away grease, sludge, mineral scale, and debris. Hydro-jetting can be a strong solution for repeat kitchen line clogs, main sewer lines with buildup, and lines that need a deeper cleaning after roots have been cut.

Main Drain Cleaning vs. Individual Fixture Unclogging

A fixture clog affects one drain, such as a bathroom sink or shower. These are often located close to the fixture and can usually be cleared quickly. A main line clog affects the larger sewer line that carries wastewater away from the whole home. When the main line is blocked, lower fixtures usually show symptoms first, including tubs, toilets, and floor drains.

Main line problems require more powerful equipment and very often a camera inspection. A camera can show roots, cracks, pipe separation, a belly in the line, or heavy scale. If the pipe is structurally damaged, cleaning may solve the immediate backup but not the root cause. In that case, we explain the options clearly before any repair is recommended.

Drain Cleaning Near You: Same-Day and Emergency Service

Do we have emergency service? Short answer – yes. United HVAC, plumbing and electrical offers same-day drain cleaning in many Bay Area locations. United works 7 days a week including holidays. While waiting for the technician, stop running water, do not flush toilets, and avoid using sinks, showers, dishwashers, or washing machines. More water entering a blocked line can cause the backup to spread.

If a toilet is about to overflow, turn off the small shutoff valve behind the toilet. If sewage is present, keep children and pets away from the area. Do not pour chemical cleaners into a backed-up drain before a plumber arrives. They may not fix the issue and can make the work area unsafe.

Drain Cleaning Service Cost in the Bay Area

Drain cleaning cost depends on the type of drain, blockage location, cleanout access, method required, and whether camera inspection or hydro-jetting is needed. A simple bathroom or kitchen drain usually costs less than a main sewer line service. The drain cleaning normally starts from $250 per line.

Before work begins, our technician explains the recommended service and provides upfront pricing. If the problem is more serious than a normal clog, we show what we found and discuss the next step.
