Finding a hidden water leak in your Tbilisi flat
Leak detection means tracing where a hidden water leak is coming from before anything gets opened up, then repairing the pipe, joint or seal at fault. The price depends on how many checks the search takes and on the repair itself, and we quote after seeing photos of the stain or damp area. You can book by phone, text or WhatsApp, with coordination in English.
- Wet ceilings, damp walls and mold
- Meters that move with every tap closed
- Supply pipes, drains and bath seals checked in turn
- Opening walls only where the evidence points
Warning signs
How a hidden leak shows itself
Leaks behind tiles or under floors rarely announce themselves with a puddle. They show up as a slow change you only notice over days or weeks.
Damp walls
Paint that bubbles, plaster that crumbles at the skirting, or a tide mark creeping up from the floor next to a bathroom.
Mold
Black spots in one corner or behind a wardrobe. Some mold is only winter condensation in a cold Soviet-era flat, which is why it needs checking rather than guessing.
A spinning meter
The small dial on your water meter keeps turning while nothing in the flat is using water.
A higher bill
Consumption jumps without any change in how you live. On a shared building meter, neighbors may notice it first.
Sounds and loose tiles
A faint hiss inside a wall at night, grout that stays dark, or floor tiles that start to lift or sound hollow.
Test it yourself
A simple meter test you can do today
Before anyone comes, this check tells you whether water is escaping from the supply side. It is completely safe and takes about an hour.
- 1
Stop all use
Close every tap, wait for the toilet cistern to finish filling, and make sure the washing machine and dishwasher are not running.
- 2
Photograph the meter
Take a clear picture of the numbers and the small red or black dial.
- 3
Wait
Leave everything untouched for 30 to 60 minutes, then take a second photo.

Compare
If the reading has moved, water is going somewhere. If it has not, the leak is more likely in a drain, a seal or another flat.
A running toilet is the most common innocent explanation. Put a few drops of food coloring into the cistern and wait twenty minutes without flushing. Colored water in the bowl means the flush valve is leaking, which is a quick fix covered on our toilet and tap repair page.
Our method
How the source is found, step by step
- 1
Map the damage
The plumber looks at where the wet area sits and what is directly above, behind or beside it: a shower, a bath, a toilet, a riser or a kitchen sink.
- 2
Rule out the non-plumbing causes
Rain through a facade crack, condensation on a cold wall and a blocked air conditioner drain all look like leaks. If the damp sits under an indoor AC unit, read about air conditioners leaking water first.
- 3
Isolate the supply
Valves are closed one at a time while the meter is watched. When the dial stops, the section with the leak has been found.
- 4
Test the drains separately
Water is run into each drain in turn, one fixture at a time, while the wet spot is watched. A drain leak only appears when that fixture is used.
- 5
Inspect what is reachable
Traps, the space behind the bath panel, the joints behind the toilet and any visible pipe runs are checked by eye and by hand for moisture.
- 6
Open only with agreement
If the evidence points inside a wall or floor, the plumber shows you where and why, and a small inspection opening is made only after you agree.
Reading the clues
Supply leak or drain leak: why the difference matters
| Clue | Supply pipe leak | Drain or seal leak |
|---|---|---|
| When it is wet | All the time, day and night | Mostly after showers, baths or washing up |
| The meter test | The dial keeps moving | The dial stays still |
| The water itself | Clean, no smell | Grey, soapy or with a sewer odor |
| How it spreads | Steadily, often along the pipe route | In bursts, usually below the fixture |
| Typical cause | A corroded steel section or failed joint | A cracked trap, old grout or failed silicone around a tray |
The answer changes the repair. A supply leak under full pressure needs a pipe section replaced. A seal leak around a shower tray may only need the old silicone cut out and redone, although water that has been soaking under tiles for months can take a long time to dry out.
Who pays
Who is responsible when the water comes from elsewhere
From the flat above
If the source is in your upstairs neighbor's bathroom or kitchen, the repair usually belongs to that flat's owner, and so, in most cases, does the conversation about damage below. Photos of your ceiling, dated messages and our plumber's explanation of the source give both sides something concrete to work from.
From a shared pipe
When the leak is in a riser or another pipe serving several flats, it is normally handled through the building administrator or the residents' association. Arrangements vary from building to building, so ask how repairs are shared in yours.
In a rented flat
Tenants should report the problem to the landlord with photos as soon as it appears. Who arranges and pays for the search and the repair is set by your lease and what you agree together.
This is general practical guidance, not legal advice. For a serious dispute with a neighbor, a local lawyer can explain your rights.
The fix
After the source is found: the repair
- Replacing a corroded steel section with modern pipe up to a sound joint
- Remaking a failed joint or valve connection
- Renewing a cracked sink or bath trap and its washers
- Cutting out and resealing failed silicone around a bath or shower tray
- Tightening or replacing the seal between a toilet and its soil pipe
Any tile or plaster opened during the search is left neat so a tiler or decorator can close it. Walls and ceilings need to dry fully before repainting, which can take weeks after a long leak, and mold should be cleaned only once the source has stopped. When the real culprit turns out to be a slow drain that backs up and spills over a seal, clearing the blockage has to come before any resealing.If water is actively pouring rather than seeping, the emergency plumber page explains what to do first. More general plumbing help is on the main plumbing page.
FAQ
Frequently asked questions
Can you find a leak without breaking tiles?
Often, yes. Isolating sections with valves, testing drains one by one and checking accessible joints narrows most leaks down before anything is opened. If an opening is needed, it is kept as small as possible and agreed with you first.
My ceiling is wet but the neighbor upstairs says nothing is leaking.
That is common, because the leak may be under their floor where they cannot see it. A check in their bathroom, with their permission, usually settles it. The building administrator can help arrange access.
Is mold always a sign of a leak?
No. In older blocks with cold outer walls, winter condensation causes a lot of mold. A leak tends to produce a patch that stays damp in dry weather and grows from one point.
My water bill doubled. Where should I look first?
Run the meter test on this page. If the dial moves, check the toilet with food coloring. If both are clean, a hidden supply leak is likely and worth a visit.
How long does it take to find a leak?
It depends on how many fixtures and pipe runs are involved and how accessible they are. Clear photos and a meter test done in advance usually make the search shorter.
Who buys the replacement pipe and fittings?
Usually you do, from a list the plumber gives you with exact sizes. Another arrangement can be agreed when booking.
Should I tell my landlord before the search?
Yes. Send photos first, and agree who arranges the visit. If water is actively coming through, stop it and inform the landlord at the same time.
