Drain and Sewer Pipe Leak Repair in San Mateo, CA

Cast iron drain stacks in older homes crack and scale with age, and plastic joints can separate if a line was poorly supported. These leaks often show up only when an upstairs fixture runs.

Floor Drain and Backwater Valve Repair in San Mateo

A basement floor drain that backs up during heavy use or a storm typically points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced without trouble.

Waterproofing for Older Northern California Homes in San Mateo, CA

Many older homes in San Mateo and across Northern California were not built with modern waterproofing techniques, making them more prone to basement leaks. Older neighborhoods in Northern California include prewar and postwar homes with galvanized supply lines and cast iron or clay sewer pipe that are nearing the end of their life. FBL Plumbing focuses on retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.

Sump Pump Repair and Installation in San Mateo, CA

Many basements rely on a sump pit to handle storm runoff and groundwater. Strong winter storms can bring days of heavy rain to Northern California, saturating ground and pushing water into crawlspaces and sewer lines. Pumps from brands like Zoeller, Liberty and Wayne fail most often from a stuck float or a burned-out motor after sitting idle for months. We repair or replace the pump, check the check valve and route the discharge well away from the foundation. A battery backup is worth considering because big storms often knock out power.

Exterior Waterproofing Solutions in San Mateo, CA

For comprehensive basement leak prevention, exterior waterproofing involves excavating around your foundation and applying waterproof membranes or coatings. This creates a strong barrier against moisture intrusion from the outside. While more involved, this method offers excellent long-term protection against water damage, especially for older homes in San Mateo.
