Gas Line Replacement
Marin, Sonoma & Napa County’s Premier Gas Pipe Replacement
Gas lines endure daily use in most homes to provide fuel to a number of appliances and home comfort systems, leading to considerable wear and tear over time. Corrosion can worsen these effects, causing small cracks, pinholes, and other issues, potentially resulting in the need for your gas pipes to be replaced.
Ongaro & Sons conduct thorough inspections to identify any damage and provide robust, long-lasting replacement of outdated or compromised gas pipes. Contact us today at 415-741-2820 or request services online to schedule an inspection and replace damaged gas pipelines.

Signs You Need to Replace Your Gas Pipes
Recognizing signs that your gas pipes need replacement is crucial for the safety and efficiency of your home’s infrastructure. Here are several indicators to watch out for:
Age of Pipes
Gas pipes have a lifespan, typically ranging from 20 to 50 years, depending on the material. If your pipes are approaching or have exceeded their expected lifespan, replacement may be necessary to prevent leaks and ensure reliability.
Corrosion
Rust or corrosion on the pipes clearly indicates deterioration. Corrosion weakens the pipes' integrity, making them more prone to leaks or even bursting. Inspect visible pipes for signs of rust, especially in older homes or areas, like North Bay, with high humidity.
Leaks
The most obvious sign of a problem is the presence of gas leaks. If you smell gas or notice hissing sounds near the gas lines, evacuate the area immediately and contact a professional. Leaking gas is highly dangerous and requires immediate attention.
Low Gas Pressure
If you notice a decrease in gas pressure throughout your home, it could indicate blockages or leaks in the pipes. This can affect the efficiency of your appliances and pose safety risks.
Physical Damage
Physical damage to the pipes, such as dents, bends, or visible cracks, can compromise their structural integrity. These damages may have occurred due to accidents or natural wear and tear over time.
Increased Gas Bills
A sudden increase in your gas bills without a corresponding increase in usage could indicate that gas is escaping somewhere within your system, leading to inefficiencies and wasted energy.
Outdated Material
If your home still has pipes made from outdated or problematic materials, consider replacing them with safer and building code-compliant materials for optimal home and system safety.
Regular inspections and maintenance by qualified professionals can help identify these issues early and prevent potential hazards. If you suspect any problems with your gas pipes, it’s essential to act promptly to ensure the safety of your household.
