How to Find and Remove Water Leaking Through Walls

water leak through walls

Learn how to locate the water leak through walls from checking your water in system and how to repair it. Also find out why cleaning the deposit moulds and moss from the leaking walls is important to be removed, here is the quick process to clean those mosses.

How to detect water leaks in walls

Water leaks in walls are disturbing not only because of their unsightly appearance, but also because they are unhealthy for the mess and sludge they create and are an added drain in the wallet.

Whether your wall is made of concrete finish from assembled hollow blocks, or a drywall, a water leak inside these walls will definitely find a messy way to show itself on the surface.

Not all water leaks are as evident as water visibly flowing down the wall to the floor.

It is possible that the leak is just coming from a tiny or slight breach on the joint connection in the piping system hidden behind the walls.

In such a case, the leak may not manifest itself unless enough moisture accumulates and is aggravated by gathering moulds and moss, which should then require a repair.

Check for Water Leaks in the System

If you are to focus on addressing such leaks on walls, you might as well make sure that the water leaks are not only where you find them by the moisture marks they create on your wall.

It is possible that some leaks may be underground.

In such cases, they may not be visible and may only be properly located using sophisticated testing equipment.

water meter

The best way to check for other leaks is through a water meter inspection:

  • Close all possible outlets of water in your household – faucets, water closets, sinks, showers, lavatories
  • Observe your water meter closely.
  • Your water meter gauge should stop moving.
  • If it continues to move fast, it means water is escaping somewhere in the water line in substantial quantity.
  • If the meter’s movement is slow as to be almost negligible, it may come from the wall behind which you suspect a water leak.

How to stop water leakage from wall

To repair the water leak, you need to access the cause of the leak which is the water pipe itself.

Before you break any wall, check your house plan for the water piping system to determine how the pipes are positioned inside the walls.

If the plans are unavailable, observe if the spread of the moisture marks are horizontal or vertical.

If horizontal, you may have to cut the drywall from end to end of the marks measuring horizontally.

If vertical, you may have to cut from the top end of the marks to about two feet downwards. It is likely that the breached portions of the pipe are located right here.

How to clean mold off walls

molds in the wall

After repairing the pipe, clean the surrounding area of the moulds and moss that have gathered.

Most drywalls are made of plasterboard or gypsum board and are easy to replace:

  • Simply cut a piece of such a board sized enough to fit the hole you opened
  • Fasten the board using screws
  • Patch up the edges of the repair board to level off with the entire wall and finish with a matching paint

If the wall is concrete, the procedure will be the same, although the materials may be different.

After you have restored the pipe and you are certain that the leak has been repaired, there are a few more things to do.

Make sure that the moulds and moss that have gathered are cleaned out so as not to induce decay inside the wall and not serve as breeding place for insects.

Replace the hollow blocks, or stones, and close the opening as a concrete finish should be.
