Have you considered how frequently your home's exterior should be cleaned? This crucial maintenance task is often overlooked but should ideally be performed once or twice a year, or more often in certain conditions.

Though it may not be at the forefront of your mind, experts emphasize the importance of regular exterior cleaning. Doing so helps preserve the integrity of your home’s materials and can prevent expensive repairs down the line.

Here, cleaning professionals provide their best cleaning advice on how often to tackle this task and why it's so important.

Recommended Frequency for Exterior Cleaning

According to Carolina Kazimierski, co-owner of Sophia's Cleaning Service, "I suggest cleaning the exterior once or twice a year. It's not something that requires frequent attention, as your home’s exterior is designed to withstand the elements, and cleaning can be a labor-intensive job!"

However, Karina Toner, operations manager at Spekless, notes that homes located in areas with high pollen, pollution, salt from the sea, or proximity to trees should consider cleaning more often, ideally every six to nine months.

“Cleaning the exterior eliminates dirt, mildew, algae, and pollutants that can damage siding and paint, leading to costly repairs,” she explains. “It also enhances curb appeal and helps maintain property value.”

Why Hiring Professionals is Recommended

Given its importance, it's best not to do it yourself.

Many outdoor cleaning tasks can be done independently, but this one is best left to the professionals, according to our cleaning experts.

Karina states, "Professionals are trained to safely and effectively pressure wash or soft wash your home without harming paint, siding, or landscaping. They also utilize commercial-grade equipment and eco-friendly cleaning solutions that outperform store-bought products—saving you time, effort, and avoiding potential repair costs."

This may seem counterproductive if you aim to save money, but remember that cleaning siding without causing damage and power washing require skill, both crucial for effective exterior cleaning.
