Can Damp and Mould Really Affect My Health?

Yes, if you have damp and mould in your home you’re more likely to have respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system. Sealing your shower or retiling your shower to fix the waterproofing will fix the mould issue once and for all.

Who’s Affected?

Some people are more sensitive than others, including:

  • babies and children
  • elderly people
  • those with existing skin problems, such as eczema
  • those with respiratory problems, such as allergies and asthma
  • those with a weakened immune system, such as those having chemotherapy.
How Does it Affect Your Health?

Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances. Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Moulds can also cause asthma attacks.

These people should stay away from damp and mould.

Causes of Damp and Mould

Mould and damp are caused by excess moisture. Moisture in buildings can be caused by leaking pipes, leaking showers, rising damp in basements or ground floors, or rain seeping in.

HIDDEN Mould Damage

Surface mould growth is annoying, ugly and hard to clean, however, if a lot of moisture has gone behind your shower wall cavity, structural damage can occur.  This is a real nightmare and simply wiping the area is not the solution. This generally occurs when there is evidence of:

  1. Leaky cold & hot water supply lines.
  2. Cracked tile & grout.
  3. Vapor drive.

Failed Shower Waterproofing

A failure of your shower will affect the backing board in your shower first.  You may notice tiles in your shower become loose tile.  This occurs when the backer board swells or loses it structure from all the moisture, causing the glue to fail and the tiles to hence fall off the wall or floor.

Diagnosing Hidden Mould & Rot Behind Shower

  • Investigate the crawlspace or room below your shower.  If the leak is quite significant, this area will show signs of water damage.
  • Inspect the adjacent wall of your shower also.  If your shower shares a common wall with a bedroom or closet,  ALSS Bathrooms will be able to detect water leakage by cutting a small hole into the sheeting to see if there is any water damage. If so, a shower repair needs to be conducted – either by sealing shower or by removing tiles depending on the severity of the damage.

Ensure First That Leak is Not a Plumbing Issue

The first to do is to make sure that the issue with leaking shower stalls is not a plumbing issue. That is to ensure that the pipes taps spouts are not leaking or facilitating water ingress. A good Licensed Plumber will be able to test and service these items including a pressure test if required to ensure that the core issue is not related to the plumbing. Also get your plumber to also carry out a flood test (using dye) to confirm the waterproofing in the shower is the issue.


Sealing a Shower to Prevent Mould

OK so you have determined the water is not leaking through the plumbing and a dye test has proven that the water is leaking through the tiles/grout/water proofing membrane. You need to fix the leak by sealing shower or retiling it.
