Problem resolved, Great job! I have found my new plumber and would highly recommend this company. Very professional, and friendly service! Fair pricing for plumbing work! Thanks guys! Thanks for being our new plumber.Posted on Google Lisa HolleyTrustindex verifies that the original source of the review is Google. Great experience with Drain & Water company. They scheduled my appointment quickly and fixed my air gap issue, getting my dishwasher working again. Jose provided excellent customer service with clear, fast communication. Thomas, the technician, was friendly, professional, wore booties before entering my home, and completed the repair quickly. The price was reasonable. Highly recommend!Posted on Google Leo LópezTrustindex verifies that the original source of the review is Google. Repipe Champions Plumbing and Rooter did an excellent job from start to finish. The team was professional, on time, and explained everything clearly before starting the work. The repipe was done faster than expected and the quality was top-notch. They left the place clean and made sure everything was working perfectly before leaving. Highly recommend them for any plumbing work.Posted on Google Barbara WeissTrustindex verifies that the original source of the review is Google. I got 3 estimates for a trenchless replacement of my sewer pipe from the front yard to the street. I was very impressed by Alex who came out to look over the project in order to make an accurate estimate. He made notes of my concerns about certain large plants which would need to be uprooted and assured me that they would be set aside and replanted. It was also necessary to remove 3 stones from a custom walkway near the entry point of their equipment and, again, Alex made a note of the extra attention required and included it in his written estimate. Alex explained the process, step by step from exposure of pipe, to hole digging, to permit and replacement. He gave me a best and worst case timeline (depending on when a city inspector would be available to sign off). The estimate was in my email box by the end of the day. The crew arrived on schedule and all work was done promptly and completed on schedule. There was just one hour when I was unable to flush the toilet due to the work in progress. Thomas was there to oversee the project and make sure things were done correctly and that care was taken to protect my landscaping and stone pathway. I could not be more satisfied with the work done and how much attention was paid by Thomas to leaving my property in good and clean, tidy repair. I recommend this company!Posted on Google gudni gudnasonTrustindex verifies that the original source of the review is Google. I have had guys come out to snake a toilet when two other contractors had failed to clear the clog. Admittedly, it was not easy… I know this because their snake came with an inspection camera and a video feed. They had their work cut out for them. The clog was not just at the toilet, but continued far down the plumbing line. They worked really hard, we’re really fair and professional. Most of all they got the job done, and got it done right! Thanks! You will be my go to in the future.Posted on Google David SchneiderTrustindex verifies that the original source of the review is Google. Fantastic! TrenchFree connected me with Axel at Drain & Water to scope out my sewer line woes. Their thorough attention to detail at the free estimate and competitive pricing won me over, and they did not disappoint! Prompt, efficient, and high-quality work. I was kept updated every step of the way, turning what could have been a major headache into a stress-free repair.Posted on Google Sergio MunozTrustindex verifies that the original source of the review is Google. Drain & Water have been servicing company facilities since the beginning of 2025 and without a doubt Axel and Thomas always get the work done in a timely manner at an affordable price.Posted on Google Karin McClungTrustindex verifies that the original source of the review is Google. Our sewer line backed up yesterday. This morning we were in desperate need of getting this problem fixed ASAP. Two years ago DRAIN AND WATER, INC had done an incredible installation of a TRENCHLESS DRAIN in our yard, so I called them to see if they also cleared blocked sewer drains. I spoke with Oscar, explained the situation and he arranged to have a truck come out. IN LESS THAN 30 MINUTES, their truck arrived with Thomas and Axel who got right to work and had the blockage removed within 15 minutes! It was amazing! Axel and Thomas are true professionals, they were kind, courteous, and explained what needed to be done. They also gave us information about other services DRAIN AND WATER, INC offer. I highly recommend DRAIN AND WATER, INC and will definitely call them in the future for plumbing and drain problems. Thank you Oscar, Axel and Thomas, for a great job! TWO BIG THUMBS UP 👍👍 AND FIVE STARS ⭐⭐⭐⭐⭐!

Water Leaks Are Costing You More Than You Think
Every day your water leak goes undetected, you’re losing money and risking serious damage to your Silicon Valley home. Water leaks don’t just increase your utility bills—they compromise your property’s structural integrity, create dangerous mold growth, and can lead to catastrophic flooding.
Common signs you have a water leak:
- Unexplained spikes in your water bill
- Damp spots on walls, ceilings, or floors
- Musty odors or visible mold growth
- Sound of running water when fixtures are off
- Warm spots on floors (indicating hot water line leaks)
- Cracks in your foundation or driveway
- Lush patches of grass in your yard
- Low water pressure throughout your home
- Water meter continues running when all water is turned off
In Silicon Valley’s competitive real estate market, water damage can devastate your property value. Historic homes in San Jose, mid-century properties in Palo Alto, and modern developments in Cupertino all face unique leak challenges—and ignoring them only makes repairs more expensive.
Professional Water Leak Detection & Repair
At Drain and Water, we’ve been Silicon Valley’s trusted water leak repair specialists since our founding. Our family-owned business combines cutting-edge TrenchFree™ technology with old-fashioned customer service to deliver leak solutions that protect your property without destructive excavation.
What is Water Leak Repair?
Water leak repair is the professional process of locating, diagnosing, and fixing leaks in your home’s water supply system. This includes everything from visible fixture leaks to hidden slab leaks beneath your foundation. Professional leak repair involves advanced detection equipment, precise diagnostics, and expert repairs that address the root cause—not just the symptoms.
What is a Slab Leak?
A slab leak occurs when water pipes running beneath your home’s concrete foundation develop cracks or breaks. These underground leaks are particularly dangerous because they go unnoticed while continuously damaging your foundation, creating sinkholes, and wasting thousands of gallons of water.

FREQUENTLY ASKED QUESTIONS ABOUT WATER LEAK REPAIR
How much does water leak repair cost in Silicon Valley?
Water leak repair costs vary based on leak location, accessibility, and severity. Simple fixture leaks may cost $150-$400, while slab leak repairs typically range from $500-$4,000+. At Drain and Water, we provide free leak detection estimates and transparent pricing before beginning any work. Financing options are available through Wisetack.
How do I know if I have a hidden water leak?
Check your water meter before bedtime when no water is being used. Take a reading, then check again in the morning before using any water. If the meter has moved, you have a leak. Other signs include unexplained water bill increases, damp spots, musty odors, or the sound of running water when all fixtures are off.
Can you detect leaks without tearing up my property?
Absolutely. Our advanced leak detection technology—including electronic sensors, thermal imaging, and acoustic devices—locates leaks with pinpoint accuracy without destructive excavation. Our exclusive TrenchFree™ repair methods then fix the problem while preserving your landscaping and hardscaping.
How long does water leak repair take?
Simple fixture leaks can be repaired in 1-2 hours. Slab leak repairs typically take 4-8 hours depending on accessibility. Complex repiping projects may take 1-3 days. We provide accurate time estimates during your initial consultation and work efficiently to minimize disruption.
Do you offer emergency water leak repair services?
Yes! We provide 24/7 emergency leak repair service throughout Santa Clara and San Mateo Counties. Call (408) 564-0580 anytime for immediate assistance with burst pipes, major leaks, or flooding situations.
What causes slab leaks in Silicon Valley homes?
Slab leaks commonly result from: soil shifting (especially in areas built on former farmland), pipe corrosion from acidic soil, poor initial installation, excessive water pressure, abrasion from gravel in soil, and age-related pipe deterioration. Silicon Valley's seismic activity can also contribute to slab leak development.
Will my homeowner's insurance cover water leak repair?
Coverage depends on your policy and the leak's cause. Sudden, accidental leaks (like burst pipes) are typically covered. Gradual leaks from poor maintenance usually aren't. We provide detailed documentation to help with insurance claims and work directly with adjusters when needed.
How can I prevent water leaks in my home?
Regular plumbing inspections, monitoring water pressure (should be 40-80 PSI), replacing aging pipes proactively, installing leak detection devices, maintaining proper drainage around your foundation, and addressing small leaks immediately all help prevent major leak problems.
What's the difference between a water leak and a sewer leak?
Water leaks involve your home's pressurized supply lines bringing clean water in. Sewer leaks involve drain lines carrying wastewater out. Water leaks typically cause water damage and high bills. Sewer leaks create health hazards and foul odors. Both require professional repair but use different techniques.
Can tree roots cause water line leaks?
Yes. Tree roots naturally seek water sources and can penetrate and damage water supply lines, especially older clay, cast iron, or deteriorated pipes. Our video camera inspections identify root intrusion, and we offer solutions including root removal, pipe lining, and strategic rerouting.
How accurate is your leak detection technology?
Our multi-method approach achieves 95%+ accuracy in leak location. We combine electronic detection, thermal imaging, acoustic listening, and pressure testing to pinpoint leaks within inches—not feet. This precision minimizes property disruption and reduces repair costs.
Will my homeowner's insurance cover leak detection?
Coverage varies by policy. Many insurers cover sudden, accidental leaks but not gradual damage. We provide detailed documentation to support insurance claims. Check with your provider about coverage specifics.
Do you repair leaks in all types of pipes?
Yes. Our technicians are experienced with all pipe materials including copper, PEX, CPVC, PVC, galvanized steel, polybutylene, and cast iron. We repair or replace damaged sections using the most appropriate materials for your specific situation.
What is TrenchFree™ technology?
TrenchFree™ is our exclusive patented method for repairing underground pipes without traditional excavation. Using specialized equipment and techniques, we access and repair pipes through minimal access points, preserving your landscaping, driveways, and hardscaping while delivering superior results.
How long do water leak repairs last?
When performed correctly with quality materials, professional leak repairs should last 20-50+ years depending on the method used. Our epoxy pipe lining carries a 50-year expected lifespan. Traditional pipe replacement using copper or PEX should last 50+ years. We back our work with industry-leading warranties.
Can you repair leaks in historic homes?
Absolutely. We specialize in working with Silicon Valley's diverse property types, including historic homes dating to the 1800s. We understand the unique challenges of older plumbing systems and use techniques that preserve your home's historic integrity while modernizing its plumbing reliability.
