Professional Exterior House Cleaning Services

What Clean Exteriors Actually Mean

Your home looks the way it should again. No more embarrassing stains greeting you every time you pull into the driveway. No more wondering what the neighbors think.

Clean siding, walkways, and driveways don’t just look better—they last longer. When you remove the mold, mildew, and buildup that’s eating away at your surfaces, you’re preventing expensive repairs down the road. That’s money staying in your pocket instead of going to contractors fixing damage that could have been avoided.

You get your weekends back too. No more spending Saturday mornings fighting with a rental pressure washer that barely works, or scrubbing stains that won’t budge. The job gets done right the first time, and you can actually enjoy your clean outdoor spaces instead of constantly maintaining them.

House Power Washing Process

Here's Exactly What Happens

First, we assess your property and identify the specific cleaning challenges. Not every surface needs the same approach—your vinyl siding requires different pressure and cleaning solutions than your concrete driveway or wooden deck.

We protect your landscaping and outdoor fixtures before we start. Plants get covered, electrical outlets get sealed, and anything that could be damaged gets proper protection. This isn’t a rush job where we hope for the best.

Then we apply the right cleaning solutions and use appropriate pressure for each surface. High pressure for tough concrete stains, gentler methods for delicate siding. We rinse thoroughly to remove all cleaning residue, leaving surfaces truly clean without any chemical buildup that attracts dirt faster.

You’ll see the difference immediately. Surfaces look brighter, stains are gone, and your property has that “just built” appearance again. The whole process typically takes a few hours, depending on your property size, and you can use your outdoor spaces the same day.

How often should I have my house power washed in Maryland?

Most Maryland homes benefit from professional power washing every 1-2 years, but it depends on your specific situation. If you have a lot of trees around your property, you’re dealing with more organic growth and may need cleaning annually. Homes in full sun with less vegetation can often go two years between services. The key is not waiting until stains become permanent or start causing damage. If you’re noticing green or black streaks on your siding, or your concrete surfaces are looking dingy, it’s time for a cleaning regardless of when you last had it done.
Not when it’s done correctly with the right equipment and experience. The damage you see from power washing usually comes from using too much pressure or the wrong cleaning approach for specific materials. We adjust pressure and technique based on what we’re cleaning—vinyl siding gets treated differently than brick, and both are different from concrete. We’ve been doing this long enough to know what works and what causes problems. That’s why we carry insurance and why we take time to assess your surfaces before we start cleaning.
Power washing uses heated water while pressure washing uses regular temperature water. Both use high-pressure water streams to clean surfaces. For most residential exterior cleaning, the terms are used interchangeably, and either method can be effective depending on what we’re cleaning. Heated water can be more effective on grease stains and organic growth, but it’s not always necessary. We choose the best method for your specific cleaning needs and surface types, whether that involves heated water or not.
A typical single-family home takes 2-4 hours to power wash completely, including setup, preparation, cleaning, and cleanup. Larger homes or properties with extensive concrete areas, decks, or heavy staining take longer. The time also depends on how much preparation is needed to protect landscaping and outdoor fixtures. We don’t rush the job—proper preparation and technique take time, and that’s what ensures good results without damage. Most homeowners can plan on having their outdoor spaces back to normal use the same day we finish.
You don’t need to be home during the entire service, but we do like to walk through the property with you beforehand if possible. This helps us understand any specific concerns you have and identify areas that need special attention or protection. If you can’t be there for the initial walkthrough, we can work from detailed instructions and photos. We’ll always contact you if we discover anything unexpected that needs your input. Many of our customers drop off keys and head to work, coming home to a clean property.
Remove or secure any loose outdoor furniture, decorations, or items that could be damaged by water or blown around. Close all windows and doors, and let us know about any areas where water intrusion could be a problem. If you have delicate plants or flowers near the house, point them out so we can give them extra protection. Turn off any outdoor electrical equipment, but don’t worry about covering outlets—we handle that protection. The main thing is clearing the work areas so we can access all surfaces safely and efficiently.
