Water Damage Mold

This is going to be the simplest direct correlation cause/effect page you have ever read. It is also very repetitive. But it cannot be emphasized enough that water in any form brings mold. It does not cause mold. But water acts as a receptor. Mold is everywhere in our lives.


Like dust it floats through the air. Whenever the mold happens to hit water it attaches itself and immediately begins a process whereby within 24-48 hours it is growing into a “mold problem”.When you have had water damage then you likely have had mold growth. If you had a sudden rush of water that damaged something and then immediately went away then you may be OK. The issue then will be in determining if all the water is gone or if moisture remains. As long as there is remaining moisture, remember the first paragraph mold likes water in any form, mold can attach itself and begin to grow.

Unintended Consequences – Simple Mistakes

mold problems

For example. You leave your car window open during a rain storm. That is an example of a sudden amount of water that then goes away. Now you dry out the car, run the heater, let it dry the next day, etc. Will you have mold? The answer is maybe. Maybe, because it depends on how well and how quickly you dried the interior of the car. You may have some water damage mold that will begin growing in the pad below the carpet. If moisture remains. Even if under the seat or in the seat cushions – if that moisture remains for 24-48 hours you will likely begin to have a mold problem.

Water And Carpet

Mold also grows when water is dropped on carpet in a home and the pad beneath the carpet is not properly dried. It is far too common for people to clean up a major spill and then think – it is good enough. When in fact it is not. This is a very real problem and many people simply overlook it.

Outdoor Drainage And Water Damage Mold

Poor drainage for landscaping outside a home can also cause a problem. Ever see stains on the stucco of a home where water creeps up near the landscaping? This water is dangerous because if it finds even the smallest hole you will end up with water behind the wall. When you go behind the exterior fascia of a home what do you find? You find insulation – insulation can act as a sponge. Wet insulation is very difficult to dry and is a great place for mold to grow – and grow unseen. This is an example where visual water damage has lead to a water damage mold problem that can go unseen for months even years.


It is also very common when the exterior of a building or home has not been properly maintained. Improper roof drainage or even a leaky roof is a major problem where visual water problems can lead to an unseen mold problem. If the exterior fascia of a home is improperly maintained or damaged it serves as type of pipeline for water to get behind walls. Once this happens it once again makes the insulation wet and then you will likely get mold.

Mold Behind Your Drywall

Beyond the insulation there is also a problem with the interior drywall of homes. When drywall gets wet it oftentimes will trap water and lead to mold. This is why special drywall is used in the wet areas of a home. Wet areas are normally thought of as the bathrooms and kitchens. This special drywall is mold resistant but it was not used in the past. While a new home may have it – older homes oftentimes do not. Be aware though that this drywall is mold resistant – mold can still grow on it and you cannot ignore water damage mold problems just because it is in a newer home with the special drywall.

sink mod

Under sinks is also a common area to find a problem. Sinks have many places where water can leak. Not only do they have water lines and drains under the sink but you are also relying upon the seal around the sink and around the faucet to protect you from water falling down into the lower cabinet area. These under sink cabinet areas are especially vulnerable also because most people normally have a lot of items stored below and they rarely take a good look under the cabinet to determine if there are any water leaks. But this is exactly what someone should do.

What Do I Do?

Mold is a serious issue but not one that cannot be taken care of quickly and efficiently with a little diligence on the part of the homeowner. Check under the sink areas for water damage and for mold that can be forming and you may not even know it. Look at your sink when washing – is the caulking around the sink and faucet in tact? You do not need to hire a plumber to fix it – just buy some $5 caulking at home depot and do it yourself. A little maintenance goes a long way. This is the same for shower areas and sink areas in the bathroom. Check the seals and make certain they are in working condition. If not – fix it. It is as easy as using Elmer’s Glue when you were in pre-school and can save you a lot of mold issues.I know most of us are very busy in our daily lives and hardly have the time to do the maintenance that our grandfathers once did. It is strongly advisable to once or twice a year have a handyman go through your home to do a little preventative mold testing and maintenance– tighten seals, fix fascia, check for water damage, re-seal tubs and sinks, tighten down toilets – do all the work that our grandparents knew how to do. It sounds trivial and like something you can put off – but really keeping your largest investment, your home, properly maintained is worth every penny. And if you avoid a mold problem and the potential related health risks – then it is worth much more than the few bucks it cost for the handyman.If you take nothing away from this article – take this – where there is water damage – you better guard against mold. Seeing damage anywhere in a home whether inside the bathroom, under sinks, or outside on fascia – if you see it you are likely to be at extreme risk for mold. Take care of it.
