Our Power Washing Process

How We Protect While We Clean

We start by walking your property with you, identifying what needs attention and any areas that require special care. Your landscaping, windows, and delicate surfaces get protected before we start.

The actual cleaning uses commercial-grade equipment with adjustable pressure settings. Different surfaces get different treatment—your vinyl siding gets cleaned differently than your concrete driveway. We’re not just blasting everything with maximum pressure and hoping for the best.

After cleaning, we do a final walkthrough to make sure you’re satisfied with the results. Your property gets left cleaner than we found it, with no damage to plants, surfaces, or anything else you care about. The whole process typically takes a few hours, depending on your home’s size and what surfaces we’re cleaning.

What's Included in Professional Service

House power washing covers your siding, trim, and exterior surfaces that make the biggest visual impact. We handle vinyl, wood, brick, and composite materials with the right pressure and cleaning solutions for each surface type.

Driveways, walkways, and patios get the heavy-duty treatment that removes oil stains, tire marks, and the deep-set grime that makes concrete look permanently dirty. Deck cleaning brings back the original color of your wood or composite decking without the damage that happens with DIY attempts.

We bring our own water when needed and handle all the setup and cleanup. Your job is to point out any problem areas or concerns. Our job is to make your exterior look like you just moved in, without you spending your weekend fighting with equipment or worrying about damaging something expensive.

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

Most Harmony Hills homes benefit from professional power washing every 1-2 years, though it depends on your specific situation. Homes with a lot of tree coverage or those facing north tend to develop mold and mildew faster due to less direct sunlight. If you’re seeing green or black streaks on your siding, or if your home looks dingy compared to when it was first cleaned, it’s time for another treatment. Maryland’s humid climate means exterior surfaces stay damp longer, creating ideal conditions for organic growth that makes houses look older than they are.
Professional power washing with proper technique and equipment won’t damage your surfaces—that’s exactly why experience matters. Different materials require different pressure settings and cleaning approaches. Vinyl siding gets cleaned with lower pressure than concrete driveways. Wood surfaces need special attention to avoid gouging or splintering. The problems happen when people use too much pressure or hold the nozzle too close to delicate surfaces. We adjust our equipment and technique based on what we’re cleaning, and we’re insured specifically because we take responsibility for protecting your property while we work.
Power washing uses heated water while pressure washing uses cold water—both use high-pressure water streams to clean surfaces. For most residential exterior cleaning, the terms are used interchangeably, and the technique matters more than the water temperature. Hot water can be more effective for removing grease and oil stains, but cold water pressure washing handles most residential cleaning needs perfectly well. What really makes the difference is using the right pressure setting, proper cleaning solutions when needed, and knowing how to clean each type of surface without causing damage.
Power washing costs depend on your home’s size, the surfaces being cleaned, and how much buildup we’re dealing with. A typical single-story home might run $200-400, while larger two-story homes with extensive deck or driveway cleaning can cost more. We provide upfront pricing after seeing your specific situation—no surprises or hourly charges that keep climbing. Most homeowners find professional service costs less than they expected when they factor in equipment rental, their time, and the risk of having to repair damage from DIY mistakes. We’re happy to provide a clear estimate based on what you actually need cleaned.
Concrete cleaning is one of the most dramatic improvements we provide. Driveways and walkways take a beating from vehicles, weather, and foot traffic, building up oil stains, tire marks, and embedded dirt that makes them look permanently stained. Professional equipment and technique can remove stains and discoloration that seemed permanent, bringing back the original concrete color. We use appropriate pressure settings that clean effectively without creating those etched lines that happen when inexperienced operators use too much pressure. The difference in your home’s curb appeal after professional concrete cleaning is usually the most noticeable improvement.
Move any outdoor furniture, decorations, or vehicles away from the areas being cleaned. Close all windows and doors, and let us know about any loose siding, trim, or other issues you’ve noticed. If you have delicate plants or landscaping near the house, point them out—we’ll take extra care to protect them during cleaning. Make sure we have access to an outdoor water spigot and electrical outlet if needed. Most preparation takes just a few minutes, and we handle the rest. If you have specific problem areas or stains you’re concerned about, show us those when we arrive so we can give them extra attention.
