11 Warning Signs Of Serious Water Damage In Your Home

When purchasing or renting a property and when selling a house, it is critical to recognize the indicators of water damage or future water damage. Water damage caused by a flood, fire, or leak can destroy a structure and result in mold development, posing a health concern to the home’s residents.

Water damage is occasionally apparent through the presence of visible leaks. In certain circumstances, water damage may go undetected for years. Continue reading to learn how to recognize subtle water damage indicators in your house and how to take preventative measures to avoid more damage.

1. Mold Growth

Mold spores require moisture to develop and thrive, which is why mold is never found in a dry environment. Examine your ceiling or drywall for dark areas. Crusts can also form on carpets, particularly if water has penetrated the flooring from beneath.

Mild mold can be a sign of condensation in certain circumstances. In other cases, it may be a sign of a significant long-term leak concealed behind your walls.

Mold indicates that there is an excessive amount of water in your home, regardless of the source. Mold is a significant issue since it is potentially hazardous to one’s health. If you see or smell mold, contact an expert like Moisture Master Pros LLC or similar companies to assess the situation and propose the best method for preventing and fixing water damage. 

2. A Musty Smell

Increased humidity or dampness within your home’s interiors is a solid sign of water damage. Each of these signs is associated with a musty odor. High humidity and moisture levels promote mold growth, resulting in a musty stench. Consider this a clear indicator of bathroom water damage. The odor can be relatively strong in regions where there has been water damage.

Water damage emits a musty odor reminiscent of damp paper or cardboard boxes. These types of odors are common in older homes, particularly in the attic or basement. Keep an eye out for any unexpected changes in odor that may occur within your home. 

3. Excessive Water Bills

Maintaining a record of your monthly expenses is generally a good idea. A substantial increase in your water bill could indicate a plumbing problem.

Don’t be concerned about slight fluctuations in your bills, as they will occur at some point. However, if your water consumption has remained consistent while your bill has increased significantly, you may have a problem.

Conduct a plumbing check of your residence. Inspect any visible pipes and appliances, including toilets, sinks, and showerheads. Additionally, it would help if you know how to spot water damage. On the other hand, brown discoloration is a dead giveaway that you’re dealing with a leak.

4. Out-Of-date Water Supply System

One of the most apparent indicators of home water damage is an out-of-date water supply system. While the pipes themselves are often in good shape, the connections and faucets frequently cause problems.

This is why it’s highly suggested to inspect the water supply system every year. Consider disconnecting your water supply if you’re going to be out of town for an extended period. Furnaces and air conditioners, for example, may require routine maintenance and inspections.

5. Dripping Water Sounds

One of the first signs of water damage is sound. Detect dripping water, leaky faucets, creaky floors, and even rushing water. These sounds may have existed from the start when the plumbing system was in good condition. Changes in these sounds should be observed, as should the introduction of new noises.

6. Pools And Puddles

If you observe any dripping or leaking, this may result in the formation of pools of water. Remove any strange puddles and return later to determine if they have resurfaced. If this occurs, there is a possibility of a leak or seepage.

7. Ruined Walls And Ceilings

While visible evidence of water damage to walls and ceilings is expected, early signs of damage are frequently disregarded. Bubbled or flaking paint or wallpaper are the first indicators. Water leaking through the walls can produce fractures in the drywall, causing it to expand and contract without appearing wet. Drooping drywall, damp drywall, and spongy walls and ceilings are all possibilities.

8. Health Complications

Have you been frequently ill recently? Mold growth in your home could be a contributing factor to your frequent flu or cold symptoms. Certain varieties of mold are especially harmful, and it is critical to destroy them as quickly as possible to avoid further health concerns.

9. Extremely Low Temperatures

At times, water damage makes it difficult to keep a home warm. If your heater appears to be constantly running, your interior walls may be damp. Moisture draws heat away from walls as it evaporates, and water damage can have a detrimental effect on a home’s thermal envelope.

10. Warped Floors 

When you walk on your floor, does it make a sound? Water causes wood floors to swell over time. As a result, the flooring becomes uneven, bent, or distorted. The mild discoloration will occur as a result of significant and persistent leakage. In contrast to plasterboard, which produces brown stains, damaged wood darkens. It may easily be confused as a coffee stain.

Is your flooring made of plastic? Fortunately, because carpet absorbs moisture, it will be easier to identify water damage. If you discover an area of your carpet that is moist and spongy, there is probably a leak underneath. Are you walking on a slanted surface? Assume that the layers of your floor are wet. Early discovery and treatment may be all that’s required to save your flooring.

11. Discoloration

Yellow or light brown marks on your ceilings or walls indicate water damage. A leaking pipe or roof may be causing discoloration on the interior of your home. If you notice discoloration on the exteriors, it could be the result of an overflowing gutter, leaving apparent wet spots on the siding.

If your gutters are overflowing, have them removed immediately to avoid causing damage to your foundation. Additionally, you may need to place runners on your downspouts to direct water away from your property.


Any water leak professional will tell you that detecting and repairing the damage quickly are the most critical factors in determining the extent and cost of water damage. While sure signs of water damage are readily apparent, others will require a trained eye. If your property has been flooded, it is vital to know who to contact for water damage restoration. This way, you can ensure that the source of the water and the extent of the damage can be detected and corrected.
