How to Deal with Bathroom Water Damage

Since the bathroom is exposed to water usage the most, it is also the room that’s most at risk of water damage. Now, such damage can be seen or unseen – and in both cases, the damage shouldn’t be ignored.

Moisture and water damage can be harmful to health because the growth of bacteria can be absorbed by the body. As for the house itself, it will also be at risk. I know of bathrooms that have literally crashed to the floor below because of structural breakage caused by water damage.

It is therefore important to recognize the types of water damage that can affect your bathroom. Doing so will minimize the risks of spending a lot of money on water damage repairs while keeping your family safe as well.

Mold and Mildew

Yeah, mold and mildew can be quite common in bathrooms because of the humidity. Regular cleaning and allowing fresh air to circulate in your bathroom can often solve this problem. However, if you notice persistent mold and mildew even with proper ventilation, that could signify a hidden problem.

Moisture buildup is the primary cause of mold and mildew. When you always see mold and mildew in your bathroom, check for cracks on the tiles or for decaying caulk – as these can be the causes of moisture retention and buildup. Also, you can try applying pressure on the wall to see if you can sense some movement inside. In such cases, you are already seeing signs of water damage that are causing mold and mildew to develop in your bathroom.

Mold and mildew removal may be easy to deal with under normal circumstances, but that is not so when these are caused by water problems. Water damage restoration can also cost a lot when the condition is really uncontrollable.

Warped Walls

When drywall is exposed to frequent moisture, bubbles can appear on the surface of walls. When left unattended, this can eventually start to break into pieces and create a hole in your bathroom’s wall. In fact, if the wood has become too soft, applying a light pressure can already create a hole in the wall.

This is a photo of a bathroom renovation my team worked on. Yeah, it was a case of warped wall, but we discovered it just in time so the damage was just minimal.

This type of water damage can be repaired by removing that portion of the wall by cutting through it. You can then replace the damaged piece and paint over it. Before doing so, however, I would recommend checking on any plumbing issues too, as there can be a leak inside the wall.

A DIY person can probably handle the repairs for this type of water damage if it’s just a minor issue. But if you think that the problem is big, it would be wise to hire a professional. A contractor often has a connection with a plumber, so a leak can be fixed properly (if any) and everything else will be handled professionally (plaster repair, painting, etc.).

See the bubble? Touching it made the air inside move. This is a clear sign of water damage due to moisture inside the wall.

Always be conscious of gaps between tiles and the bathtub. Remember, moisture and water can seep in between these gaps and damage the walls and floor of your bathroom. The water damage can cause rotting inside walls and floors and also lead to the formation of mold and mildew. Wall and floor restoration can also be costly if left unattended for too long because the damage will only get worse.

Soft and Spongy Floor

If the subfloor in your bathroom is made of plywood, hidden leaks and moisture can cause internal rotting. If the affected area is around the toilet, you will even feel that it’s unstable when you’re using it.

Feeling the floor as soft and spongy is already a sign of water damage. Please do something about it – replace the flooring as soon as possible before the entire flooring system collapses. This happened to a friend of mine – fortunately, nobody got hurt. But the damage was so great that it cost them a lot of money.

Dealing With Water Damage in the Bathroom

As home owners, I want you to always be aware of the structural integrity of your house. Now that you know the basic types of water damage that can happen in your bathroom, I’m sure you can spot hidden damages before things can get worse.

I always encourage early repairs because this will cost less and not expose your family to unwanted accidents too. So please don’t delay on the repairs when you see water damages present in your bathroom (or any part of the house, for that matter). If you can’t do the repairs yourself, call a general contractor.
