  • Ask whether the system includes a sump and pump, and what happens in a power cut
  • Get the guarantee in writing, ideally insurance-backed for larger jobs
  • For showers and wet rooms, ask what tanking system is used under the tiles
  • Check that surface water and gutters have been ruled out first

Typical Dublin price: €200–€800. The final price depends on:

Frequently Asked Questions

Can one crack be sealed without redoing everything?

Often yes, with resin injection, if the rest of the structure is sound.

How much does leak sealing cost in Dublin?

Typically €200–€800. The exact price depends on access, the extent of the problem and whether parts or materials are needed.

How urgent is leak sealing?

Deal with active leaks quickly.

What is the difference between damp-proofing and waterproofing?

Damp-proofing resists moisture. Waterproofing resists water under pressure, as in basements below ground level.

Do I need a sump pump?

If the system collects water, like a cavity drain membrane, a sump pump removes it. A battery backup is recommended.

Can a shower leak without me seeing it?

Yes. Water can get through grout and failed seals into the floor or wall for months before you see stains.
