Commercial Awning Cleaning in St. Louis, MO.

Awnings can become very dirty when left neglected for a period of time. This project shows the importance of awning cleaning and maintenance. Recently a building owner in St. Louis, MO, In the Clifton Heights neighborhood reached out, the condition of the commercial awnings was the main concern. The black canvas tops had become dull and were covered in mold, mildew, and lichen spores. They needed more than a quick rinse, so our team at Exterior Cleaning Solutions STL scheduled a commercial awning cleaning to restore appearance and protect the fabric.

We started the project by assessing the visible soiling and confirming the awnings were canvas material. That informed our approach, because canvas can be damaged by high-pressure washing. To avoid harm, we used safe, low pressure cleaning methods designed for fabric awnings. Those methods loosened and removed the biological growth without driving water into seams or backing materials.

During the cleaning, we paid close attention to areas where mold, mildew, and lichen had built up, working methodically until those contaminants were lifted from the fabric. Using low pressure allowed us to clean thoroughly while protecting the structure and finish of the awnings. This approach is standard for commercial awning cleaning where longevity and appearance both matter.

Once the cleaning was complete, we applied a fabric conditioner to the canvas. The conditioner is meant to preserve the life of the awning, so it helps the fabric resist future soiling and extends the interval between cleanings. Applying a conditioner after cleaning is an important step for commercial clients who want to maintain curb appeal and protect their investment.

We completed the work with careful cleanup of the surrounding area and a final inspection of each awning panel. The building owner was informed about what we did and why, including the reason we chose low pressure techniques and the benefit of conditioning the fabric. Our team at Exterior Cleaning Solutions STL in St. Louis, MO follows this routine whenever a commercial awning cleaning job requires both safe handling and long-term protection.

This project illustrates the practical approach we take for awnings that show biological growth. For commercial properties in St. Louis, MO that have canvas or vinyl awnings collecting mold or lichen, the combination of safe low pressure cleaning followed by a conditioner helps restore appearance and preserve the material. If you are seeing similar issues on your building, a professional commercial awning cleaning is the right first step.
