Fast, professional hot tub leak repair in Dallas-Fort Worth. We find and fix leaks in portable hot tubs, built-in spas, Jacuzzis, Sundance, HotSpring, and more. Mobile service. Same-day available.
A leaking hot tub isn’t just annoying. It’s expensive. Water loss damages your deck, ruins your foundation, and can destroy your spa’s internal components. Every drip represents money down the drain – and potential structural damage to your home.
At PoolBurg, we don’t clean hot tubs. We repair them. Our leak detection and repair service is purpose-built for homeowners across DFW who need a reliable, certified technician to find and fix the problem – fast.
Hot tub leaks rarely happen without a reason. Here are the most common causes we see across Dallas, Plano, Frisco, and the rest of North Texas.
The plumbing inside a hot tub is under constant pressure and thermal stress. Over time:
PVC fittings crack from freeze damage
Glue joints fail after years of expansion and contraction
Underground lines (for built-in spas) develop pinhole leaks
Flex pipes become brittle and split
Signs: Water loss when the spa is off, wet spots under the tub, or a soft area in your yard near the spa location.
The acrylic or fiberglass shell of your hot tub can crack from:
Improper leveling (the tub sits unevenly, causing stress fractures)
Freeze damage (water expands inside the shell walls)
Impact damage (heavy objects dropped on the tub)
Age-related embrittlement
Signs: Visible cracks, water weeping through the shell, or water appearing on the exterior of the tub.
Many leaks originate at the components:
Pump wet end seals
Heater gaskets
Control pack connections
Jet housing seals
Drain valve seals
Signs: Water pooling around the pump, heater, or plumbing connections. Often intermittent – leak appears only when jets are running.
Each jet in your hot tub has a housing that penetrates the shell. When these seals fail:
Water leaks from behind the jet
The jet may feel loose
Water loss increases when jets are on
Signs: Water dripping from behind the jet, damp insulation around the jet housing, or visible gaps between the jet and shell.
Your spa heater has a metal tube that water flows through. When corrosion creates a pinhole:
Water leaks from the heater housing
The heater may trip the breaker
You may see rust-colored water
Signs: Water at the bottom of the spa cabinet near the heater, error codes related to heater flow, or moisture inside the control box.
We do not guess. We don’t pressure test and walk away. Our proven 5-step leak detection process finds every leak – even the hidden ones.
Before we touch anything, we look:
We check every visible component
We look for wet spots, rust, and mineral deposits
We inspect the spa cabinet for water damage
We check the foundation or deck area for moisture
Tools: Flashlight, mirror, moisture meter
We isolate the plumbing system and pressurize it with air or water:
We close off the plumbing loop
We apply precise pressure
We watch for pressure drop
We listen for air escaping
Tools: Pressure test kit, isolation valves, gauge
When we suspect a hidden leak, we use ultraviolet dye:
We inject dye into the spa water
We run the system to circulate the dye
We use UV light to trace the dye to the exact leak location
Dye glows bright green or pink under UV – impossible to miss
Tools: UV dye, UV flashlight, water sample bottles
For spas with multiple components, we isolate each zone:
We test the pump separately
We test the heater separately
We test each jet bank individually
We test the circulation system
Why it matters: This tells us exactly which component is failing, not just that a leak exists.
Before we repair, we confirm:
The exact leak location is marked
We have identified the root cause (not just the symptom)
We have selected the correct repair method
We have quoted the repair cost
No surprises. No guesswork. Complete transparency.
Cracked PVC: Cut out and replace with new plumbing
Failed glue joint: Remove old pipe, re-glue or use slip couplings
Split flex pipe: Replace section with rigid PVC or reinforced flex
Underground leak: Excavate, repair, backfill, and test
Pump seal replacement: Remove pump, replace wet end seal, reassemble
Heater gasket replacement: Remove heater, replace gasket, reinstall
Jet housing repair: Remove jet, replace housing, re-seal
Drain valve replacement: Remove valve, install new one, pressure test
Hairline cracks: Epoxy injection and surface repair
Larger cracks: Fiberglass patch and color-matching
Chips and gouges: Acrylic or gel coat repair
Water intrusion: Dry out components, replace damaged parts, seal box
Corroded connections: Clean or replace terminals
Base gasket failure: Replace gasket, reseal control box
This usually means:
A cracked plumbing pipe under the tub
A leak at the drain valve
A split in the floor of the shell
Water from the pump seal running down
Our method: We lift or tilt the spa (portable) or excavate (built-in). We pressure test. We find the exact point.
This is the most frustrating leak type. It means:
The leak is underground (built-in spa)
The leak is inside the cabinet and evaporating
The leak is behind insulation (hidden)
Our method: Dye test + UV light or isolation pressure test. We will find it.
This tells us:
The leak is in the jet plumbing
The leak is at a jet housing
The leak is at a diverter valve
Our method: We isolate jet bank by bank and pressure test each one.
Note: Actual pricing depends on severity, access, and component type.

We provide upfront quotes before any work begins.
Portable hot tubs are easier to access but harder to move:
We can tip or lift the tub for access
We use portable pressure testing equipment
We can often repair on-site without moving the tub
We seal the repair and test before we leave
Common portable brands we repair: Sundance, HotSpring, Caldera, Jacuzzi, Bullfrog, and all major brands.
Built-in spas require more work:
We use dye and UV tracing
We pressure test the entire plumbing loop
We may need to remove coping or tile
We repair underground leaks with targeted excavation
We restore the area to original condition
Common built-in manufacturers we repair: Pentair, Hayward, Jandy, and all custom-built spas.
Short-term losses:
Higher water bills (up to $200/month for a serious leak)
Chemical imbalance (more chemicals needed)
Heating costs (you’re heating water that’s leaving)
Long-term damage:
Deck rot (wood damage under the spa)
Foundation issues (water pooling near the house)
Mold and mildew (inside the spa cabinet and under the deck)
Component failure (pumps run dry, heaters overheat)
Electrical hazards (water intrusion into control boxes)
The smart move: Fix the leak now. The repair will pay for itself in 1-3 months of saved water and chemicals.

A standard hot tub loses 1-2 inches per week from evaporation. If you lose more than that, or if water appears on the deck or under the spa, it’s a leak. We can measure your water loss rate to confirm.
Sometimes. Small shell cracks can be repaired underwater with epoxy. But most plumbing and component leaks require draining for proper access and repair.
Diagnosis: 1-2 hours
Simple repair: 1-3 hours
Complex repair (excavation, multiple leaks): 1-3 days
If your spa is still under manufacturer warranty, some leaks may be covered. But many warranties exclude:
Freeze damage
Improper installation
Lack of maintenance
We can help you determine if the repair is warrantable.
We guarantee our leak detection. If we cannot locate the leak after a full diagnosis, you pay nothing. This rarely happens – we find leaks.
