Professional Flagstone Cleaning in Southern Maryland – Restore Your Outdoor Stone the Right Way

Flagstone patios, walkways, and hardscapes are beautiful features that add value and charm to your home. But over time, these surfaces get dirty, slippery, and stained. If you’re looking for professional flagstone cleaning in Southern MD, GutterDogs has the expertise and tools to clean and protect your stonework properly.

We serve Prince George’s County, Calvert County, Charles County, and the surrounding Southern Maryland region with top-rated exterior cleaning services. Whether your flagstone is discolored, covered in algae, or simply overdue for maintenance, we’ll bring it back to life safely and effectively.

Why Is Flagstone Cleaning Important?

Flagstone is a naturally porous material, which means it easily traps moisture, bacteria, dirt, and organic growth. Over time, your once-vibrant patio or walkway can turn dark, green, or even slick. That buildup isn’t just ugly—it’s dangerous.

Algae, mildew, and bacteria can grow deep within the stone, causing discoloration and slippery surfaces that pose a fall risk. DIY cleaning often misses these deep layers or uses pressure that damages the stone. That’s why it’s important to call professionals like GutterDogs, who understand how to clean flagstone safely and thoroughly.

Our Safe and Effective Flagstone Cleaning Process

At GutterDogs, we use a specialized soft washing system that removes surface and embedded grime without damaging your stone. Here’s what sets our process apart:

• ✅ Low-pressure soft washing – Safe for natural stone

• ✅ Biodegradable cleaning solutions – Break down organic buildup like algae and bacteria

• ✅ Professional surface cleaners – Deliver even, streak-free results

• ✅ Expert care – Tailored to your specific type of flagstone and layout

We don’t just rinse the surface—we sanitize and restore it. That means your patio, path, or stone wall stays cleaner longer and looks better than ever.

Common Problems with Dirty Flagstone in Southern Maryland

Here in Southern Maryland, our humid climate and seasonal weather create the perfect conditions for grime to grow on outdoor surfaces. Homeowners often notice:

• Dark stains from algae or moisture

• Green patches caused by bacteria

• Rust marks from patio furniture or irrigation

• Dirt tracked in from foot traffic

• Slippery surfaces during rain or dew

If you’ve noticed any of these on your hardscapes, it’s time to consider professional flagstone washing services.

Flagstone Surfaces We Clean

We clean all types of natural stone and hardscape surfaces, including:

• Flagstone patios

• Walkways and garden paths

• Pool decks

• Outdoor fireplaces

• Retaining walls

• Entryways and steps

• Stone sitting walls

No matter where your flagstone is located, we’ll restore its natural color, texture, and beauty—without damaging it.

Remove Bacteria, Not Just Stains

Most homeowners don’t realize that what looks like dirt or mold is often biological growth. Flagstone absorbs water, which leads to the growth of:

• Bacteria

• Algae

• Lichen

• Mildew

Our flagstone cleaning in Southern MD is designed to kill and remove these organisms at the root. That helps prevent early stone deterioration and keeps your walkways and patios looking cleaner for longer.

When to Schedule Flagstone Cleaning

We recommend having your stone cleaned at least once a year—or more often if your property is shaded, near trees, or exposed to frequent foot traffic or moisture. Some great times to schedule a cleaning include:

• Spring – Prep your patio for summer entertaining

• Summer – Keep walkways safe and beautiful

• Fall – Clean up after summer and remove leaves, pollen, and grime

• Before selling your home – Boost curb appeal and value instantly

If you’re seeing discoloration, green buildup, or slick spots—it’s time to call in the pros.
