Shed Mold & Mildew


So you built the perfect shed and now it has been taken over by shed mold & mildew.  This is a real possibility as shed mold happens all the time and can ruin your shed.  You can take certain steps to prevent the mold.  Some of these steps are done in the building process, so make sure you understand what can be done.  Once you have the mold you will need to find out how to get rid of it and prevent it from coming back.

Shed Mold & Mildew – Building Process Prevention

Apply caulk to outside of shed.  That’s right, caulk the outside seams around windows, doors, trim and vents.  Don’t caulk the interior as it is not a good enough seal and can still be penetrated by water.

Install vents in your shed.  You can install ridge, gable or soffit vents which allows better air flow.  This air flow will prevent stagnation and then increased humidity.  This humidity increase will allow the mold to grow.  So proper air ventilation is a must.

Shed Mold & Mildew – How do I get rid of this stuff?

There are many home recipes on the internet.  However, bleach always come to mind with getting rid of mold.  You can dilute 1/2 -1 cup of bleach for every gallon of water. How much bleach really depends on your mold growth (and your tolerance).  You will need to scrub the area with the solution and make sure to rinse it good and let it dry.  If you do this take safety precautions with ventilation as bleach can be harsh.

Shed Mold & Mildew – Now it’s gone, how do I prevent it?

Dehumidifier.  A good dehumidifier will be a must if you have a shed that is constantly under attack with humidity and subsequently mold.

Exhaust fans. These help with air circulation.  Putting it in while building the shed is perfect, but if you did not do that, then there are other options.  The easiest option is a window fan.  Just place it in the window and turn it to exhaust.  It will get air moving and help keep it dry.  Exhaust fans are easy to find.

Moisture absorbents.  There are many options on the market when it comes to moisture absorbents.  Basically they are canisters of absorbents you put out in the shed and they draw in the moisture.  Damp Rid is one that many people use and it does a good job. However, you can also use kitty litter as that has worked for some.

Shed Mold & Mildew – Conclusion

Be aware of mold whether you are in the process of planning for a shed or you already have a shed built.  If you are in the planning stages, then make sure you build the proper prevention in your shed from the beginning.  It is easy and quick and better to prevent.  However, if you have mold, then clean it up and then do the prevention ideas outlined above.  Do all you can to prevent the mold so you can enjoy your shed for years to come.

Hope this helps,
