Keeping the exterior of your home looking clean and well-maintained is important for both curb appeal and protecting your siding from damage over time. Pressure washing is an effective way to remove built-up grime, mildew, and stains. But how often should you get this service done? The answer depends on several factors related to your home’s location, the type of siding material, and exposure to environmental elements. In this article, we’ll cover the key considerations for determining the ideal pressure washing frequency to keep your home’s exterior looking its best.
Location Matters for Pressure Washing Frequency
Where your home is located plays a big role in how often you’ll need to pressure wash the exterior. Pro Power Clean is based out of Coventry, CT where homes are more rural. In rural or wooded areas homes tend to get dirtier faster from things like tree sap, pollen, and dirt kicked up from unpaved roads. If you live in the city, soot, pollution, and construction debris can quickly build up on your siding. Coastal homes are extremely susceptible to salt spray, sand, and environmental factors like humidity can also foster mildew growth.
On the other hand, homes in drier climates with less vegetation and particulates in the air may be able to go longer between pressure washes. As a general rule, expect to need more frequent washings if your home is exposed to an abundance of dirt, moisture, vegetation, or air pollution.
Siding Material Impacts Pressure Washing Needs
The type of exterior siding material on your home also influences how often you’ll need to schedule pressure washing services. Harder surfaces like vinyl, fiber cement, stucco and brick can typically go longer between washings as they are less susceptible to damage and don’t retain stains as easily. Wood siding is more vulnerable and usually requires more frequent cleaning, as it can suffer damage like rot, splitting and discoloration if mildew and dirt are allowed to build up over time. Most siding manufacturers recommend pressure washing wood no more than once per year.
Aluminum and other metal sidings should be pressure washed annually as well to prevent oxidization and corrosion from salt, pollution and moisture getting trapped against the surface. When determining your ideal pressure washing schedule, consider the specific maintenance requirements for your home’s primary siding material as well as any trim pieces made from other materials.
Other Factors That Impact Pressure Washing Frequency
In addition to your home’s location and siding material, there are a few other situations that may require more frequent pressure washing:
Preparing for Exterior Painting – If you plan to have your home’s exterior repainted, it’s critical to start with a clean, pristine surface. Most professional painters will require pressure washing first to ensure proper paint adhesion and a flawless finish.
Removing Heavy Mildew/Mold Growth – Mildew and mold can be stubborn and cause damage if allowed to really accumulate. If you notice significant growth, don’t wait for your annual washing – get it eliminated promptly.
Prepping Home for Sale – Giving your home’s exterior a deep clean helps maximize curb appeal if you are listing it for sale. Many sellers schedule a pressure wash right before putting their home on the market.
Storm/Disaster Cleanup – After major weather events like hurricanes or wildfires, pressure washing removes debris, stains and residue left behind on home exteriors.
When to Pressure Wash Your Home – Final Tips
Pressure washing is an important home maintenance task that keeps your exterior looking great and prevents more costly repairs down the road. While every situation is somewhat unique, here are some general guidelines on frequency:
Homes in rural, wooded or coastal areas – Pressure wash annually at minimum.
Homes in urban areas – Pressure wash every 12-18 months.
Homes with wood or metal siding – Pressure wash annually.
Homes with vinyl, fiber cement or brick siding – Pressure wash every 2-3 years.
Regardless of typical frequency, plan to pressure wash whenever you notice excessive buildup of dirt, mildew, salt or environmental stains. It’s also highly recommended before painting or listing your home for sale. Work with a professional pressure washing company that is experienced with your type of home siding. They can evaluate your situation and recommend the right detergents, pressure levels and techniques to get optimal results without any damage. With some simple maintenance and periodic deep cleaning, you can keep your home’s exterior looking fresh and protect your investment for years to come.
