Drain Pipe Leak Detection in San Jose
Finding Underground Drain Pipe Leaks in San Jose Without Unnecessary Digging
Drain pipe leak detection in San Jose starts with a camera inspection of the buried drain line in your yard. The camera shows exactly where a pipe is cracked, separated at a joint or packed with roots, so we fix that spot instead of trenching the whole yard. JPM Landscape is a licensed California contractor (CA License #963784) that has built and repaired yard drainage systems in San Jose since 1984. We price every job after a free on-site estimate, because pipe length, depth and what sits on top of the line set the cost.
This page covers the drains in your yard: French drains, catch basins, area drains and downspout lines. If the leak is in a water supply line or in a sewer line that ties into your house plumbing, a plumber is the right call. If you are not sure which one you have, that is usually clear on the first visit.
Signs Your Underground Drain Line Is Leaking
A leaking yard drain does not carry water to the outlet. It lets water escape into the soil through a crack or an open joint, and the ground above it shows the damage.
- Water pooling in the same spot after every rain
- A soggy patch of lawn that stays wet days after the rain stops
- A sunken or dipping strip of ground that follows the path of the pipe
- A downspout that overflows or a yard drain that will not drain
- Standing water near the foundation, or a damp crawl space and warped flooring after heavy rain
One sign on its own can be a grading problem. Several together, in the same place, usually mean the pipe itself has failed. Our guide to how to tell if an underground yard drain pipe is broken walks through the checks you can do yourself. If only the downspout line is backing up, an underground downspout drain that is clogged may clear with a simple hose test first. A wet lawn can also come from a leaking irrigation line, so it is worth reading the signs of a hidden irrigation leak before anyone digs.
Left through a few winters, water leaking beside a foundation stops being a lawn problem and becomes a structural one.

Drain Pipe Leak Detection and Repair Services in San Jose
Detection comes first, because the right repair depends on what the camera shows. Here is what we handle:
- Drain camera inspection: a camera runs through the line to show cracks, breaks, sags, roots and blockages on screen.
- Underground leak location: using the camera and a water flow test, we pinpoint where the line fails so digging is limited to that spot.
- Broken and cracked pipe repair: we cut out the damaged section, replace it and reconnect the line.
- Root intrusion clearing: jetting or root cutting to clear the roots, then repair of the joint they opened.
- Clog and blockage clearing: jetting out the silt, leaves and debris packed into the line.
- Downspout drain line repair: fixing or rerouting buried downspout lines and their outlets.
- Catch basin and area drain repair: repairing the inlets and connections that feed the line.
- Drain pipe replacement: new PVC pipe, correctly sloped and bedded in gravel, when a run has failed in several places.
- Troubleshooting and drainage consulting: a walk-through when you are not sure whether the cause is the pipe, the grade or the irrigation.
Clay Soil, Rainy Winters and 811 in San Jose
Some properties in Santa Clara County have clay-heavy soil that swells when saturated in the rainy season and shrinks through the dry summer. Where that happens, the movement can put stress on drain pipe joints over time, and a line that held for years may separate after a wet winter. Clay can also hold water against a pipe, so a small leak may wash out the gravel bed beneath it. Soil conditions vary from one property to the next, so we look at your site instead of assuming.
Most of San Jose’s rain falls between November and March. A leak that is easy to ignore in October can turn into a bigger problem by January if water collects near the foundation.
Before any digging we call 811 (USA North 811) at least two business days ahead, so buried gas, water, irrigation and electrical lines get marked. Do the same if you plan to dig yourself. Irrigation and low-voltage lines often run through the same area as a yard drain.
What Drain Pipe Leak Detection and Repair Costs
We price detection and repair after we see the line. These factors move the number most:
- How much pipe needs work, from a single joint to a full run
- How deep the pipe is buried
- What sits on top of it: lawn, planting beds, pavers or concrete
- Whether the pipe is only blocked or also damaged
- What needs restoring afterward, such as sod, planting or hardscape
A line that jets clean costs less than one that needs a trench. For typical Bay Area ranges for a spot repair versus a full replacement, see our yard drain pipe repair vs. replacement cost guide. JPM Landscape gives you a written price after a free on-site estimate, before any work starts.
Our Process
- Free on-site estimate. We walk the yard, look at where water pools and where downspouts and drains discharge, and ask how long the problem has been going on. Seeing it during or just after rain helps.
- Camera inspection. We run a camera through the accessible line to find cracks, separated joints, roots, sags or a crushed section. For an accessible line this often takes under an hour.
- Flow test. We run water through the line and watch where it goes, to confirm the failure point.
- Written scope and price. A cracked joint or short damaged section is usually a spot repair. A crushed pipe, or a line failing in several places, usually calls for replacement.
- Repair. We call 811 first, then dig only where the camera showed the failure. A single spot repair on an accessible section is often finished in a day. Longer runs, or lines under a patio or driveway, take longer.
- Restoration and final test. We backfill, repair the sod, planting or hardscape, and run water through the line with you there.
Why San Jose Homeowners Choose JPM Landscape
JPM Landscape is a licensed, bonded and insured California landscape contractor (CA License #963784) that has worked in San Jose and Silicon Valley since 1984. We have earned 12 Best of Houzz awards and a 4.9-star rating across 92 Houzz reviews.
A drain line is part of the whole yard. It runs under lawns, planting beds and patios, and it ties into catch basins, downspouts and grading. The crew that finds the failure can also repair the pipe, correct the grade and restore the surface, so the fix does not leave a new problem on top.
Projects and Experience
Yard drainage is part of the design-build work JPM Landscape has delivered across Santa Clara County since 1984. It goes in under patios, pavers and planting, not through them afterward.
Every drainage job is different, so we start with the site: where the water comes from, where the pipe runs and what sits on top of it. That is why we inspect the line before recommending a repair.
You can read what past clients say about working with JPM Landscape in the verified reviews on our Houzz profile and Google listing. Every job starts with a free on-site estimate and a written price before work begins.

Drain Pipe Leak Detection FAQ
You likely need it if the same wet spot returns after every rain, a strip of lawn is sunken along the path of the pipe, or water shows up near the foundation or in the crawl space. One sign can be a grading issue. Several together point to a failed line. A camera inspection tells you which.
The cost depends on how much pipe is damaged, how deep it is and what has to be restored, so JPM Landscape prices after a free on-site estimate. A single spot repair costs far less than replacing a full run. Our repair vs. replacement guide lists typical Bay Area ranges.
We run a drain camera through the line to see the damage, then run water through it to confirm where it goes. That pinpoints the failure, so digging is limited to one section. If the line cannot be reached from an inlet or cleanout, a small exploratory dig may be needed.
It depends on the scope of the work, the conditions on your property and local requirements. A small repair to an existing line may be treated differently from work that changes where water drains, involves a retaining wall or connects to the public storm drain. JPM Landscape can help confirm what applies to your project during the on-site evaluation. For a final answer on your address, you can also check with the City of San Jose.
A single spot repair on an accessible section is often finished in a day. A longer run, or a pipe buried under a patio or driveway, takes longer because of the extra excavation. We give you a timeline once the camera confirms the scope.
Call a landscape contractor when the line runs through your yard to a catch basin, dry well, lawn emitter or storm drain. Call a plumber if the leak is in a water supply line or a sewer line tied into house plumbing. JPM Landscape handles the yard-side drainage system, and if your problem turns out to be plumbing, we will tell you.
