San Rafael's Gas Line
Replacement Specialists
San Rafael's residential gas infrastructure spans more than a century of layered development. The Canal District and Downtown contain pre-1920 homes with original threaded black iron gas pipe — fittings corroded after a century of service and a frequent source of slow leaks. Gerstle Park and Dominican, both layered with Victorian and early-20th-century housing, share that same legacy profile. The 1950s–60s Terra Linda, Sun Valley, and Glenwood tract expansion built thousands of homes with galvanized steel and black iron, now at end of life and routinely undersized for the tankless water heaters and high-BTU range tops Marin homeowners now install. Newer Loch Lomond, Peacock Gap, and infill construction uses CSST, with pre-2008 installations frequently needing bonding remediation. Marin County Code now requires a seismic gas shutoff valve at the time of any significant gas-piping work, which we install and document on every San Rafael repipe. Repipe Champions handles all permit, preservation, PG&E, and seismic-valve filings.
Repipe Champions replaces galvanized steel, black iron, and aging CSST gas lines throughout San Rafael. Every project is permitted through the City of San Rafael Community Development — Building Division, city-inspected, and backed by our 30-year parts and labor warranty.
We coordinate the PG&E gas shutoff and restore service the same day work is completed. Free estimates for all San Rafael homeowners.

Two types of aging gas pipe dominate Marin County's older housing stock. Both carry safety and reliability risks that only full replacement resolves.
Galvanized Steel Gas Pipe
Galvanized steel was the standard gas piping material from the early 1900s through the 1960s. It corrodes from the inside out: rust and mineral scale accumulate inside the pipe over decades, gradually restricting gas flow and creating pinhole leak points that are invisible until they fail.
Corrugated Stainless Steel (CSST)
CSST flexible gas tubing was widely adopted from the 1980s through the 2000s for its ease of installation. Older CSST (pre-2008 uncoated) has a documented vulnerability to lightning-induced arc damage that can perforate the tubing wall and cause gas leaks, a known risk in the Bay Area's residential stock.
Does Your San Rafael Home Need
Gas Repipe?
These are the most common signs of a failing gas line in Marin County homes. Any one warrants immediate inspection.
Gas Odor (Rotten Egg Smell)
Natural gas is odorized with mercaptan for safety. Any persistent sulfur or rotten egg smell near appliances, the meter, or in your yard requires immediate attention: call PG&E and leave the building.
Yellow or Orange Burner Flames
Gas burners should burn blue. Yellow or orange flames indicate incomplete combustion caused by restricted gas flow, a common sign of internal corrosion narrowing galvanized gas lines.
Low Gas Pressure
If your stove, furnace, or water heater has noticeably weaker performance than it used to, internal galvanized pipe corrosion may be restricting gas flow throughout your home.
Home Built Before 1975
If your San Rafael home was built before 1975 and has never had a gas line inspection or replacement, scheduling a free estimate is a prudent safety step regardless of visible symptoms.
Rust or Discoloration at Fittings
Visible rust, orange staining, or mineral deposits around gas pipe fittings, joints, or the meter connection indicate active external corrosion, a precursor to joint failure.
Recent Seismic Activity
After any significant earthquake, a gas line inspection is recommended for homes with pre-1980 rigid galvanized pipe. Ground movement can fracture corroded joints that appeared stable before the event.
We Know San Rafael
Gas Systems
San Rafael is the largest and oldest city in Marin County and has the most varied gas pipe profile. The Canal District and Downtown contain pre-1920 homes with original threaded black iron gas pipe — much of it still in service in crawlspaces and basements, with corrosion at threaded fittings the most common leak source. Gerstle Park and the Dominican neighborhood, with their layered Victorian and early-20th-century housing, share that legacy black iron profile and frequently sit on hand-routed runs that have not been touched since installation. Terra Linda, Sun Valley, and Glenwood from the 1950s–60s tract era used galvanized steel and black iron — the largest concentration of mid-century gas pipe in the city, and the most common source of capacity issues when homeowners add tankless water heaters. Loch Lomond and Peacock Gap from the 1960s–70s mix galvanized and early CSST. Newer Bret Harte and infill developments use modern CSST. Canal-District homes near the marshline contend with elevated humidity that accelerates exterior corrosion on meter risers.
🏗️ San Rafael Gas Pipe Context
San Rafael's pre-1920 black iron in the Canal District, Gerstle Park, and Dominican is at or beyond service life — threaded fittings corrode externally over decades and produce slow, hard-to-detect leaks. Mid-century galvanized in Terra Linda and Sun Valley shows the typical internal-scale pattern that starves modern high-BTU appliances. Pre-2008 CSST installations in Peacock Gap and 1990s infill commonly need bonding remediation. Canal-District homes also see accelerated exterior corrosion on meter risers from marshline humidity. Per Marin County Code, any significant gas-piping work in San Rafael now triggers seismic-shutoff-valve installation, which we always include and document.
