In Florida, where the soil is soft and moist, it's fairly common to see home's foundations and walls settle throughout their lifespan. As this happens, small, surface level cracks can start to happen in the exterior walls and stucco. For the most part, these are harmless to the structure of the home. However, certain actions must be taken to ensure that they don't begin to cause major issues for your home.
If the cracks are large or deep, you will of course have to get them properly filled and sealed by a professional. But if they are small, you may be able to avoid this repair cost and take a more economical route.
See, with small cracks you wont have to be too worried with your home becoming unstable or the walls falling apart. But, with the frequency of rain and general high heat and humidity, these cracks can allow water to seep slowly into the exterior walls and accumulate over months and even years. After our summer storms, the sun once again begins heating things up and the moisture combined with the heat turns the cracks into a breeding ground for one of the hardest, most expensive things to get rid of; mold.
Mold growth can be slow and happen for long periods of time without you being aware. By the time you figure it out, it is far too late for an easy fix.
So... what can you do to prevent this?
One of the best things you can do to protect your home is to apply a high quality exterior paint that seals these cracks and repels water. You wont want normal interior paint or cheap outdoor paint as the walls are likely to absorb it and not create a coating over the cracks.
We use a water based acrylic paint that is specially formulated to protect the walls and stucco from forming new cracks and seals any current surface level cracks to prevent water damage. Best part is, it's backed by a Behr with a lifetime guarantee, and of course it will look great too!
If you have small cracks in your walls, especially near your windows or doors, don't wait too long to take action!
