Water Heater Repair in Millbrae, CA

Water heater failures are one of the most common emergency calls we receive from Millbrae homeowners. Many properties in and around the Meadow Glen neighborhood and the older streets west of El Camino Real were built in the mid-20th century and some still have water heaters that have been in service for 10 to 15 years or more. Hard Peninsula water with moderate calcium and magnesium content accelerates sediment build up inside tank heaters, reducing efficiency and shortening lifespan.

In & Out Plumbing & Construction repairs, replaces, and installs tank and tankless water heaters for residential and commercial properties throughout Millbrae. We service all major brands, Navien, Rinnai, Noritz, Rheem, Bradford White and handle the full scope of the job including diagnosis, parts, installation, gas line work, and permits.

Drain Cleaning in Millbrae, CA

Recurring slow drains are a common complaint in Millbrae homes, particularly in properties built before 1980. Many of these homes still have original cast iron or clay drain lines that have spent decades accumulating scale, grease, and debris and in some cases have root intrusion from the mature trees along residential streets throughout the city. Store-bought solutions provide temporary relief at best; professional drain cleaning resolves the underlying problem.



We provide drain cleaning throughout Millbrae using professional-grade snaking and hydro jetting, a high-pressure water process that clears the full pipe diameter rather than just clearing a channel through a clog. For properties with recurring issues, we recommend a sewer camera inspection to identify the root cause before committing to a repair. Emergency drain cleaning is available 24/7.

Sewer Line Services in Millbrae, CA

Sewer line problems are one of the more serious plumbing issues a Millbrae homeowner can face, and they rarely resolve on their own. The established trees throughout Millbrae's residential neighborhoods, particularly along streets near El Camino Real and Millbrae Avenue, are a common source of root intrusion into aging sewer laterals. We also see soil movement-related joint separation in older clay pipe systems throughout the city.

In & Out Plumbing & Construction provides sewer camera inspection, sewer cleaning, sewer line repair, and trenchless sewer line replacement throughout Millbrae. Trenchless methods are ideal for the established yards and limited access common on Peninsula properties, we repair or replace damaged sewer lines through small access points without excavating your landscaping.

Commercial Plumber in Millbrae, CA

Millbrae's commercial activity centers on El Camino Real, the Millbrae BART station area, and the mixed-use buildings near downtown. Businesses in these areas rely on plumbing systems that handle higher daily demand than residential properties and when those systems fail, downtime has a direct impact on operations. In & Out Plumbing & Construction provides commercial plumbing services throughout Millbrae with the same urgency we bring to residential emergency calls.
