What We Offer: Comprehensive
Water Line & Pipe Work Service

Our plumbing experts handle a full range of water line and pipe-related services, including:

Leak Detection & Pipe Repairs

We use acoustic and infrared leak detection tools to locate hidden leaks behind walls, under floors, or in your yard—without tearing apart your property. Once identified, we’ll repair or replace the damaged sections using long-lasting materials like PEX, copper, or CPVC.

Water Line Replacement

Old, corroded, or burst water lines can cause serious structural damage and water waste. We replace outdated galvanized or polybutylene piping with modern alternatives built to withstand pressure and temperature changes—extending the lifespan of your entire system.

New Pipe Installation

Whether you're building an addition or installing plumbing in a new property, we design and install water lines from scratch to ensure reliable water delivery and flow. Our team works closely with your contractors or architects to meet all city and state building codes.

Frozen or Burst Pipe Response

Cold weather can crack or rupture pipes overnight. We offer emergency services to repair or replace burst pipes quickly—minimizing water damage and preventing mold.

  • Unexpected rise in your water bill

  • Damp spots on walls, ceilings, or floors

FAQs – Water Line & Pipe Work

How long do water pipes last?

Copper pipes can last 50+ years, while PEX and CPVC typically last around 40 and 25 years respectively. Lifespan depends on water quality, pipe material, and installation quality.

Can I repair a water line myself?

Small leaks may seem DIY-friendly, but professional repairs ensure proper sealing, material compatibility, and long-term safety. Improper repairs can void insurance and cause bigger issues.

Costs vary depending on pipe length, material, and accessibility. On average, San Francisco homeowners spend $1,500–$4,000. We offer free estimates and transparent pricing.

Does my homeowner's insurance cover water line damage?

Some policies cover sudden or accidental damage but exclude long-term wear. We can help you document the issue if you need to file a claim.
