Lannon stone and concrete cleaning, New Berlin WI

For this project in New Berlin, WI, Alpha Co Enterprises provided concrete cleaning and retaining wall cleaning services for one of our permanent lighting customers. The job included cleaning and sanitizing Lannon stone retaining walls, pool deck concrete, and stamped concrete patios that were covered in mold and algae. Our crew focused on removing the biological growth and making the outdoor living areas safe and ready for use.

We began by assessing each surface to determine the level of mold and algae buildup. The Lannon stone retaining walls required careful attention because of their texture and joints, while the pool deck concrete and stamped patios needed an approach that would clean without damaging the surface patterns. As part of our concrete cleaning and degreasing service, we applied products and techniques designed to break down organic growth and lift grime away from the stone and concrete.

During the cleaning process we followed a methodical approach, working section by section. This helped ensure even coverage and effective sanitizing. For the retaining walls we used our retaining wall cleaning service, paying close attention to the mortar lines and textured areas where algae can hide. For the pool deck and stamped concrete patios we used concrete cleaning and degreasing methods appropriate for outdoor horizontal surfaces that see foot traffic and exposure to moisture.

Sanitizing was an important part of the job, because mold and algae are not just unsightly, they can also make surfaces slippery and harder to maintain. Our team applied sanitizing treatments after cleaning to help remove remaining spores and reduce the chance of quick regrowth. All work was performed with care to protect surrounding landscaping and the property’s outdoor features.

Because this was for a permanent lighting customer, we coordinated the work to fit their schedule and to avoid interfering with existing lighting installations. Our technicians took care to work around the fixtures and leave the project area clean and orderly at the end of each day.

Throughout the project, Alpha Co Enterprises in New Berlin, WI kept the homeowner informed about the steps we were taking and the services being used. The combination of concrete cleaning and degreasing with targeted retaining wall cleaning addressed the mold and algae problem across the different materials on the property.
