Bright Brothers of North Austin Before & After Photos

Algae growth behind AC units is extremely common in Texas. The constant moisture produced by the condenser, combined with the limited air flow and the unit’s close placement to your home’s exterior wall, creates the perfect environment for algae to thrive. This issue is especially noticeable on limestone surfaces, which are highly porous and allow algae to anchor deeply and spread rapidly.

Over time, the affected area develops dark green or black discoloration that continues to expand if left untreated. Beyond affecting your home’s curb appeal, untreated algae can also trap moisture against the stone, accelerating wear and contributing to long-term staining.

At Bright Brothers of North Austin, we specialize in safe, effective removal of algae from limestone and other masonry surfaces. Our process includes:

• Targeted pretreatment using professional-grade solutions designed to break down algae at the root

• Gentle, low-pressure application to protect your stone surfaces while thoroughly removing all organic growth

• Rinsing and post-treatment to ensure a clean, bright finish and help slow future regrowth

• Inspection & recommendations for moisture management and long-term maintenance

Our trained technicians understand the unique cleaning needs of Central Texas stone and environmental conditions. We ensure your home looks its best while protecting the integrity of your exterior surfaces.

Limestone homes are a signature look across Central Texas, but over time moisture, rain, and irrigation can leave the stone with dark algae streaks, dirt buildup, and discoloration—especially along the lower sections of the home.

At Bright Brothers, we use a professional soft wash process designed specifically for delicate natural stone like limestone. Instead of high pressure that can damage the surface or mortar joints, our method uses specialized cleaning solutions and low-pressure application to safely break down organic growth and restore the stone’s natural appearance.

The difference is immediate—brighter stone, cleaner lines, and a refreshed exterior that brings your home’s curb appeal back.
