About this service
What Pool Leak Detection in Houston Actually Involves
Pool Leak Detection in Houston is the process of finding where a swimming pool, spa, or pool plumbing system is losing water, then confirming the leak location before any repair begins. We pressure-test return lines and skimmer lines with a hydrostatic test pump, listen for escaping water with an acoustic listening device, and scan the shell and deck with a thermal imaging camera. A moisture meter confirms saturation behind tile or under decking. No guesswork, no digging up the whole yard.
Houston pools take a beating. Clay soil shifts through dry summers and wet winters, which cracks gunite shells and stresses buried PVC pipe. Freeze events like the ones we saw in recent winters crack above-ground plumbing and fittings. If your pool is losing more than a quarter-inch per day with the pump off, that is not evaporation. Call us for pool leak Detection near me Houston service and we will tell you exactly where the water is going.

What's included
What Our Pool Leak Detection Includes
Every diagnostic includes the core steps to find and confirm a pool leak. Repairs are quoted separately after we know what we are dealing with, so you only pay for what you need.
✓
Bucket Test and Visual Inspection
We set a bucket test to separate evaporation from a real leak, then inspect the pool, spa, deck, equipment pad, skimmer throats, light niches, and visible plumbing for signs of failure.
✓
Pressure Testing of Pool Lines
We plug and pressurize return lines, skimmer lines, and main drains with a hydrostatic test pump. A pressure testing gauge shows which line is losing pressure and how fast.
✓
Acoustic and Thermal Scanning
An acoustic listening device picks up the sound of escaping water. A FLIR thermal imaging camera shows temperature differences behind the shell or under decking. A moisture meter confirms saturation.
✓
Written Leak Location Report
You get a written summary of what we tested, what we found, and where the leak is. If a repair is needed, we quote it before we start. No guesswork, no vague recommendations.
✓
Repair and Final Pressure Test
If you approve the repair, we fix the leak the same day when possible. That may mean replacing a PVC section, resealing a fitting, or patching the shell. We pressure-test the line again and show you the gauge holding steady.
How it works
Our Pool Leak Detection Process
01
Call and Schedule
Call 832-839-4984 or book online. We ask a few questions: how much water you are losing per day, whether the pump is on or off, and whether you see wet spots. Most Houston-area jobs get same-day or next-day scheduling.
02
Bucket Test and Visual Check
We set a bucket test to separate evaporation from a real leak. Then we walk the pool, spa, deck, equipment pad, and surrounding yard. We check skimmer throats, light niches, tile lines, and the backwash line for obvious failures.
03
Pressure Testing and Listening
We isolate return lines, skimmer lines, and main drains with plugs, then pressurize each with a hydrostatic test pump. An acoustic listening device picks up the hiss of escaping water. A pressure testing gauge shows which line is losing pressure and how fast.
04
Thermal and Moisture Confirmation
A thermal imaging camera shows temperature differences where water is moving behind the shell or under decking. A moisture meter confirms saturation. If the leak is under a slab or deck, we may run a pipe inspection camera to see the break.
05
Repair and Pressure Test
Once we know the location, we repair it. That may mean cutting out a section of PVC pipe, replacing a fitting, resealing a light niche, or patching the shell. We pressure-test the line again before we leave and show you the gauge holding steady.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Acoustic Listening Device
Amplifies the sound of escaping water in pressurized lines, letting us pinpoint the leak within inches without excavation.
FLIR Thermal Imaging Camera
Shows temperature differences where water is moving behind the pool shell or under decking, making hidden leaks visible.
Hydrostatic Test Pump
Pressurizes isolated pool lines so we can watch a pressure testing gauge and confirm which line is leaking.
Moisture Meter
Confirms saturation behind tile, under decking, or in the soil so we know exactly where water is collecting.
Pipe Inspection Camera
Lets us see inside buried lines to find cracks, root intrusion, or failed fittings that pressure testing alone cannot confirm.
Sewerin Tracer Gas Detector
For hard-to-find leaks in concealed lines, we introduce tracer gas and follow it to the source with a Sewerin detector.
RIDGID and Milwaukee Tools
We use RIDGID and Milwaukee cutting, pressing, and diagnostic tools for fast, code-correct repairs on PVC and copper lines.
Real results
Before and after.
Cracked Return Line Under Deck
Before
A Memorial homeowner was losing an inch of water per day. The autofill ran constantly, and the water bill had jumped $120. The deck had a soggy spot near the skimmer.
After
We pressure-tested the return lines, found a cracked line under the deck, cut a 2-foot section, replaced the PVC and fittings, and pressure-tested it again. Water loss stopped, and the next bill dropped $80.
Failed Light Niche in Bellaire
Before
A Bellaire pool was losing water and the light niche was visibly corroded. The homeowner thought the whole pool needed resurfacing.
After
We pressure-tested the niche line, confirmed the leak, and resealed the niche with epoxy and sealant. No resurfacing needed. The repair cost $350 instead of $8,000.
Frozen Pipe Burst in Cypress
Before
After a freeze, a Cypress homeowner woke to water spraying from the equipment pad. The pool was losing water fast and the pump was running dry.
After
We responded within two hours, isolated the burst copper pipe, replaced the section with PVC, and pressure-tested the system. The pool was back online the same day.
Problems we solve
Pool Leak Problems We Solve in Houston
Houston pools leak for predictable reasons. We see the same failures over and over, and we know how to find and fix them fast.
Ask a pro →↗
Wet spots or sinking areas around the pool deck
We use thermal imaging and moisture meters to trace water under the deck, then pressure-test the lines beneath it. We locate the break without tearing up the whole patio.
Autofill runs constantly and water bill keeps climbing
We isolate the autofill, test the pool lines, and check the shell and fittings. Once we find the leak, we repair it and confirm the autofill cycles normally again.
Cracks in the pool shell or tile line
We inspect the shell with thermal imaging and moisture meters, then pressure-test the plumbing to rule out line leaks. If the crack is the source, we repair it with epoxy and sealant.
Transparent pricing
Pool Leak Detection Pricing in Houston
$250 - $1,300 depending on diagnostic and repair scope
Typical 2026 pricing for Pool Leak Detection in Houston runs $250 to $450 for a full diagnostic, including pressure testing and thermal imaging. Repairs are quoted separately and usually add $150 to $850 depending on access and parts. We quote the full price before we start, so you approve the number first. No hidden fees, no surprise line items.
Finding the leak fast saves water, protects your deck and foundation, and avoids unnecessary resurfacing. Most customers save the cost of the diagnostic in the first month of water bills alone.
01Access to the Leak
If the leak is under a deck or slab, we may need to cut concrete to reach it. That adds labor and repair cost. Leaks at the equipment pad or visible plumbing are faster and cheaper.
02Number of Lines Tested
A simple pool with two return lines is faster to test than a pool with a spa, multiple returns, and a separate suction line. More lines mean more time on the pressure testing gauge.
03Repair Type
A fitting replacement or light niche reseal is quick. A shell crack or buried pipe replacement takes longer and costs more in materials and labor.
04Emergency vs. Scheduled
Same-day and 24/7 emergency pool leak repair Houston Texas calls carry a higher rate than scheduled diagnostics. We tell you the rate before we dispatch.

What Houston Pool Owners Say
★★★★★
“Our pool was losing about an inch a day and the autofill ran constantly. Leak Detection The Heights came out the same day, pressure-tested the lines, and found a cracked return line under the deck. They cut a small section, repaired it, and pressure-tested it again. Water bill dropped $80 the next month.”

“I thought we had evaporation. They did a bucket test and proved it was a leak in the skimmer line. The tech used an acoustic listening device and found it in under an hour. Repair was quick and the price matched the quote. No surprises.”

“We manage a 40-unit complex with a pool that was losing water fast. They responded on a weekend, found a failed light niche and a broken main drain line, and had both repaired by Monday. Written report and photos for our records. Exactly what we needed.”

✓ VerifiedMost residential pool Leak Detection in Houston runs $250 to $450 for a full diagnostic, including pressure testing and thermal imaging. If we find and repair the leak the same day, repair costs typically add $150 to $850 depending on access and parts. We quote the full price before we start.
If your pool loses more than a quarter-inch of water per day with the pump off, that is a leak, not evaporation. Other signs: wet spots on the deck, cracking or settling around the pool, constantly running autofill, and a water bill that jumped without explanation. A bucket test confirms it in 24 hours.
Call a licensed leak detection and plumbing company. Leak Detection The Heights has served Houston, TX since 2013, holds a Texas State Board of Plumbing Examiners license, and repairs pool plumbing, shells, and fittings. We handle both detection and repair, so you are not coordinating two companies.
Most pool leak repairs take two to four hours once we have located the leak. Simple fitting or light niche repairs are faster. If we have to cut concrete decking to reach a buried line, plan on a full day. We pressure-test the line before we leave and show you the result.
