About the Company

Deehan Plumbing is a trusted, locally-owned plumbing service in San Rafael, CA. We specialize in comprehensive plumbing inspections designed to proactively identify and address common local issues like pipe joint failures and copper pipe corrosion. These problems, often exacerbated by our local soil and water conditions, can lead to costly leaks and water damage if left unchecked. Our thorough inspections allow us to spot early signs of wear, corrosion, or weakness in your plumbing system. By catching these issues early, we help San Rafael homeowners and businesses prevent emergencies, save money on future repairs, and ensure the long-term integrity of their property's plumbing.

Common Questions

How can a plumbing inspection from Deehan Plumbing help prevent pipe joint failures in my San Rafael home?

Our plumbing inspections include a detailed check of all visible pipe joints for signs of stress, mineral buildup, or slow leaks. In San Rafael, soil movement and temperature shifts can stress these connections over time. We identify loose fittings, corrosion, or hairline cracks before they turn into a major leak, allowing for a simple, proactive repair that prevents water damage and saves you from an emergency call.

What do you look for during an inspection to detect copper pipe corrosion, a common issue here?

During our inspection, we specifically examine copper pipes for discoloration (bluish-green stains), pitting, or thinning walls—common signs of corrosion in our area. We also assess water pH and flow rates, which can indicate internal corrosion. Early detection lets us recommend solutions like pipe lining or strategic replacements to protect your home's water quality and plumbing system integrity.

As a San Rafael homeowner, how often should I schedule a professional plumbing inspection?

We recommend a professional plumbing inspection every 1-2 years for most homes in San Rafael. Given our local issues with pipe corrosion and joint failures, annual inspections are ideal for older homes or those with original copper plumbing. This regular check-up helps us monitor the health of your system, catch problems in their earliest stages, and provide maintenance advice to extend the life of your pipes.
