What Should I Know Before Buying a House With a Pool?
Have the pool inspected separately from the house, ask for the permit history in writing, run the equipment during the inspection, and price the repairs you find before closing. Surface problems are usually cheap. Structural and hydraulic problems are not, and they are the ones worth finding early.
Key takeaways
- A standard home inspection does not cover the pool properly. Book a separate pool inspection.
- Ask for the permit history in writing. An unpermitted pool becomes your problem the day you take the keys.
- Cosmetic and structural problems look similar to an untrained eye and differ by an order of magnitude in cost.
- Run every piece of equipment during the inspection. Pumps and heaters reveal themselves under load, not at rest.
- Check the barrier against the current requirement, not the one that applied when the pool was built.
- An older pool is not a reason to walk. It is a number to negotiate with, once you know what the number is.
What should a pool inspection actually cover?
Structure and shell condition, the interior finish, tile and coping, the equipment pad under load, plumbing and any evidence of leaks, electrical bonding, decking and drainage, and the safety barrier. A general home inspection typically covers none of this in useful depth.
The distinction that matters is between what is visible and what is under load. A pool at rest looks fine. A pool with the pump running, the heater firing, and the cleaner cycling tells you far more, and that is what a proper inspection does.
Leaks are the item worth specific attention. Water loss can be evaporation, a plumbing leak, or a shell issue, and those three have wildly different costs. If there is any doubt, a dedicated leak detection test before closing is cheaper than the alternative.
- Shell structure and any cracking, with an opinion on whether it is structural.
- Interior finish condition and remaining life.
- Tile line and coping, including movement or separation.
- Every piece of equipment run under load, not just switched on.
- Evidence of leaks, and a leak test if water loss is suspected.
- Electrical bonding and equipment safety.
- Deck condition, drainage direction, and any settlement.
- Barrier, gate hardware, and any required alarms.
If the property is on septic, confirm the pool and its equipment do not sit over the drainfield or its reserve area. That is an expensive discovery to make after closing rather than before.
Which problems are cheap and which are expensive?
Finish wear, tile grout, worn gate hardware, and an ageing pump are ordinary costs. Structural cracking, a failing shell, major plumbing under the deck, and drainage that runs toward the pool are the expensive ones, and they are the ones worth identifying before you commit.
The trap is that cosmetic and structural problems can look similar. Surface crazing in plaster is normal ageing. A crack that runs through the shell in a consistent line, or one that appears with staining or water loss, is a different matter. Only someone who builds pools can reliably tell you which you are looking at.
Drainage is the quiet expensive one. Deck grading that sends water toward the pool rather than away, on clay ground that already holds water, causes long-term movement in decking and coping. It is rarely mentioned in listings and it is not cheap to correct.
| What you find | Usually | Why |
|---|---|---|
| Plaster wear or surface crazing | Ordinary cost | Expected ageing of an interior finish |
| Tile grout deterioration | Ordinary cost | Routine maintenance item |
| Old but working pump | Ordinary cost | Replaceable, and often an efficiency upgrade |
| Non-compliant gate hardware | Ordinary cost | Hardware swap, but do it immediately |
| Structural cracking | Significant | May indicate shell or ground movement |
| Persistent unexplained water loss | Significant | Could be plumbing under deck or the shell |
| Deck draining toward the pool | Significant | Ongoing movement, especially in clay |
| No permit history | Significant and awkward | Compliance follows the property |

Our page on building on clay soil explains why drainage around a pool matters so much in this region, and why it shows up in decking before it shows up anywhere else.
Why does the permit history matter so much?
Because compliance follows the property, not the person who built the pool. An unpermitted pool can complicate your own resale, create insurance questions, and in some cases require exposing buried work for inspection after the fact. Ask for the permit record in writing before closing.
This is the single most overlooked item when buying a house with a pool, and it is free to check. A pool built with permits has an inspection record showing the structure, the electrical, and the barrier were all signed off. A pool without one has no such record, and you inherit that gap.
Barrier requirements are the related trap. A pool permitted years ago may not meet the current requirement, and enforcement is generally triggered by a sale, a claim, or a complaint. Check the barrier against what applies now rather than what applied then. Our page on pool permits in Virginia covers what those requirements involve.
- Ask the seller for the permit and inspection record in writing.
- Confirm any later additions, such as a heater or spa, were also permitted.
- Check the barrier against the current requirement, not the original one.
- Ask your insurer what they will require once you own it.
- Confirm equipment ages and whether any warranties transfer.
- Get repair quotes before closing so the number is real, not estimated.
An older pool is not a reason to walk away. It is a number to negotiate with. Once you know what the repairs actually cost, the conversation moves from anxiety to arithmetic, and pools in good structural condition are frequently worth renovating rather than replacing.
Frequently asked questions
Should I get a separate pool inspection when buying a house?
Yes. A standard home inspection does not cover a pool in useful depth. A dedicated inspection covers the shell, finish, equipment under load, plumbing, bonding, drainage, and the barrier.
What does a pool inspector look for?
Shell condition and cracking, interior finish, tile and coping, all equipment running under load, evidence of leaks, electrical bonding, deck condition and drainage, and whether the safety barrier meets current requirements.
How can I tell if a pool crack is serious?
Surface crazing in plaster is normal ageing. A crack running through the shell in a consistent line, or one accompanied by staining or unexplained water loss, is different. Have someone who builds pools make that call.
What if the pool has no permit history?
Treat it as a real issue. Compliance follows the property, so it becomes yours at closing. It can complicate your own resale, raise insurance questions, and occasionally require exposing buried work for inspection.
Does the pool barrier need to meet current rules?
Check it against what applies now rather than when the pool was built. Enforcement is usually triggered by a sale, a claim, or a complaint, and a gate that no longer complies is an immediate safety issue regardless.
How much does a pool inspection cost?
Considerably less than any of the problems it finds. Prices vary by inspector and scope, and a leak detection test is usually separate. Ask what is included before booking.
Is an older pool worth renovating?
Frequently, yes. A pool in sound structural condition can be resurfaced, retiled, and re-equipped for far less than a new build. The structure is the part that determines whether renovation makes sense.
What repairs are most expensive on an existing pool?
Structural shell repair, plumbing under the deck, and correcting deck drainage that runs toward the pool. Finish, tile, and equipment are ordinary costs by comparison.
Should I run the equipment during the inspection?
Yes, all of it. Pumps, heaters, cleaners, and lighting reveal problems under load that are invisible at rest. An inspection that never starts the equipment has not told you much.
Can I negotiate the price based on pool repairs?
That is exactly what the inspection is for. Get real quotes rather than estimates before closing, so the conversation is about a specific number rather than a general worry.
Get the pool looked at before you commit
K&D can assess an existing pool’s structure, equipment, and decking so the repair number is real before you close.
