How Often Should You Wash Your House? A Homeowner’s Guide to Clean Exteriors

Owning a home is a huge responsibility. From managing finances and ensuring safety to keeping up with maintenance, the list can feel endless. However, one aspect of homeownership that often goes overlooked is maintaining the exterior of your house. Many homeowners may not realize the importance of cleaning the outside of their house regularly, or they may be unsure about how often it should be done.


Exterior house cleaning is an essential part of home maintenance that not only improves the aesthetic appeal of your home but also helps preserve the structural integrity of your property. Whether you're looking to boost curb appeal, prepare for a sale, or simply maintain your home’s value, cleaning the exterior surfaces should be a priority.


In this blog, we will explore the different factors that affect how often you should wash your house, the various exterior surfaces that require cleaning, and the best methods for washing your house washing. By the end of this guide, you'll have a clear understanding of how often you should clean your home’s exterior and why it matters.



Why You Should Clean Your House’s Exterior Regularly


The exterior of your home is exposed to the elements year-round. This means your house faces dirt, grime, dust, algae, mold, mildew, bird droppings, and other debris. Over time, these contaminants can build up on surfaces and cause discoloration, staining, or even damage to the exterior materials. Regular cleaning helps to mitigate these risks and keep your home looking fresh and well-maintained.


Moreover, some materials, such as wood siding and vinyl, can suffer from mold and mildew buildup, which can lead to decay or rot if not cleaned and maintained. Similarly, accumulated dirt can create an unsightly appearance, detracting from your home’s curb appeal. For these reasons, keeping your house clean is more than just a cosmetic concern; it’s a practical one.



Factors That Influence How Often You Should Wash Your House


How frequently you need to wash your house depends on a few key factors. Let’s explore these factors so you can tailor your cleaning routine to the needs of your home.



1. Climate and Weather Conditions


One of the most important factors that affect how often you should wash your house is the local climate. Homes that are exposed to heavy rainfall, high humidity, or extreme weather conditions may require more frequent cleaning. For instance, homes in areas with frequent rainfall or coastal environments (where salt from the ocean can corrode surfaces) may accumulate dirt, algae, and mold more quickly. Conversely, homes in drier climates may need less frequent cleaning, but dust and pollen can still build up over time.



2. The Type of Siding


Different exterior materials require different cleaning frequencies and methods. For example:





  • Vinyl Siding: Vinyl is relatively low maintenance and can generally be cleaned every 1-2 years. However, if you live in a humid climate or an area with a lot of tree cover, you may need to wash it more often to prevent algae and mildew growth.




  • Wood Siding: Wood is more porous and prone to mold and mildew growth. Wood siding should ideally be washed once a year to prevent rot and maintain its integrity. However, homes near wooded areas may require more frequent cleaning.




  • Brick or Stone: Brick and stone are durable materials that do not require frequent cleaning. They typically only need to be washed every 2-3 years unless they are heavily soiled or exposed to pollutants.




  • Stucco: Stucco is more susceptible to stains from rainwater and other environmental elements. Cleaning stucco once a year is generally recommended to maintain its appearance and prevent buildup.




3. Environmental Factors


Homes surrounded by trees or other vegetation will likely accumulate more dirt, leaves, and organic debris on the exterior. Homes located near busy roads or in urban areas with higher pollution levels may also need more frequent cleaning due to the buildup of grime and pollutants on the surface.


Additionally, areas with a high population of birds or insects may require more frequent cleaning to remove droppings or webs. Insects like ants, termites, and other pests can also leave behind marks or cause structural damage to the siding if not dealt with promptly.



4. Aesthetic and Curb Appeal


If you're planning to sell your home or simply want to improve its curb appeal, washing the exterior is essential. A clean house makes a good first impression, and regular washing will keep it looking fresh and inviting. Even if you aren’t selling, maintaining the visual appeal of your home can significantly increase its overall value.



5. Presence of Mold, Algae, or Mildew


Mold, algae, and mildew thrive in moist environments, and once they establish themselves, they can spread rapidly across your home’s exterior surfaces. If you notice any signs of mold or algae growth, it’s important to clean the exterior of your house immediately to prevent further damage.



How Often Should You Wash Your House?


Now that we’ve covered the factors that affect cleaning frequency, let’s dive into the recommended guidelines for how often you should wash your house washing based on different exterior surfaces.



1. Vinyl Siding: Every 1-2 Years


As mentioned, vinyl siding is low-maintenance and usually doesn’t require frequent cleaning. However, it’s still a good idea to wash it every 1-2 years to remove dirt and prevent algae or mold growth. If you live in a humid climate or near trees, you may need to wash your vinyl siding annually.



2. Wood Siding: Once a Year


Wood siding needs more attention due to its susceptibility to mold, mildew, and decay. It should be cleaned at least once a year, ideally in the spring or fall when weather conditions are mild. Regular washing will also help maintain its natural beauty and prevent the growth of harmful organisms that can cause wood to rot.



3. Brick or Stone: Every 2-3 Years


Brick and stone exteriors don’t accumulate dirt as quickly as other materials, so washing them every 2-3 years should be sufficient. However, if you live in an area with high pollution or frequent storms, you may need to clean them more often to maintain their appearance.



4. Stucco: Once a Year


Stucco is a more porous material, making it more prone to staining and mold growth. It’s recommended to clean your stucco exterior at least once a year to prevent these issues from arising. Homes located in wet or humid climates may require more frequent washing.



5. Concrete or Driveways: Every 1-2 Years


While concrete driveways and walkways don’t require the same level of maintenance as siding, they still need occasional cleaning. Washing them every 1-2 years will remove dirt, stains, and algae buildup. In high-traffic areas or places where oil stains accumulate, more frequent cleaning may be necessary.



The Best Methods for Washing Your House


When it comes to washing your house, there are a few different methods you can choose from. The best method for your home will depend on the material of your exterior and the type of dirt or grime you're dealing with.



1. Pressure Washing


Pressure washing is an effective and fast way to clean many types of exterior surfaces, including vinyl, wood, and concrete. It uses high-pressure water to remove dirt, algae, mold, and other debris from the surface. However, it's important to use the right pressure setting to avoid damaging the material. For example, wood siding can be damaged by too high a pressure setting, while vinyl may get dislodged if pressure is too strong.



2. Hand Washing


For more delicate surfaces, like stucco or painted wood, hand washing with a soft cloth or sponge and mild soap is often the best option. This method allows for more control and prevents damage to the exterior. It’s also a good option for removing stains or mold spots that require extra attention.



3. Chemical Cleaners


In some cases, especially when dealing with mold or stubborn stains, chemical cleaners may be necessary. Ensure that any cleaners used are appropriate for the material of your house washing and are environmentally friendly to avoid damaging your landscaping or polluting water sources.



4. Gutter Cleaning


While not technically part of exterior washing, cleaning your gutters is another crucial maintenance task. Clogged gutters can lead to water damage, staining, and even foundation issues. Cleaning gutters should be done at least twice a year—once in the spring and once in the fall.



Conclusion


Maintaining the cleanliness of your home’s exterior is an essential part of homeownership. Not only does it keep your property looking fresh and appealing, but it also helps prevent long-term damage to your home’s structure. The frequency with which you should wash your house depends on several factors, including the type of siding, climate, and surrounding environment.


As a general rule of thumb, you should wash your house’s exterior every 1-3 years, but keep in mind that some materials may require more frequent cleaning. Whether you choose to pressure wash, hand wash, or use chemical cleaners, make sure you select the right method for the surface material to avoid damaging your home. By staying on top of exterior cleaning, you’ll ensure that your home remains in great condition for years to come.
