Professional Exterior House Cleaning Services

See the Difference Immediately

Your home’s exterior takes a beating. Maryland’s humid summers breed mold and mildew. Winter salt eats away at surfaces. Pollen coats everything in a thick, stubborn layer that garden hoses can’t touch.

When we’re done, you’ll see your property the way it looked when you first fell in love with it. Clean siding that actually reflects light instead of absorbing grime. A driveway that looks like concrete again, not a canvas for every oil stain and weather mark.

But it’s more than just appearance. Proper power washing removes the organic growth that breaks down your siding, decking, and concrete over time. You’re not just getting a clean house – you’re extending the life of expensive exterior materials and protecting thousands of dollars in property value.

House Power Washing Process

Simple Process, Professional Results

We start with a thorough inspection of your property. Different materials need different approaches – what works perfectly on concrete can damage vinyl siding. We identify what we’re working with and plan accordingly.

Next comes the pre-treatment. Stubborn stains, organic growth, and built-up grime get targeted with appropriate cleaning solutions. This isn’t about blasting everything with maximum pressure – it’s about working smarter.

Then we power wash using the right pressure and technique for each surface. Your siding gets treated differently than your driveway. Your deck gets different attention than your walkway. We adjust our approach based on the material, the level of soiling, and the age of the surface.

Finally, we do a complete walkthrough with you. You’ll see exactly what we’ve accomplished, and we’ll point out any areas that might need future attention.

How often should I have my house power washed?

Most Cohasset homes benefit from power washing every 1-2 years, but it depends on your specific situation. Homes with more shade tend to develop mold and mildew faster due to moisture retention. Properties near busy roads accumulate more dirt and pollution. If you’re seeing green or black streaks on your siding, or if your concrete surfaces look permanently stained, it’s time for a cleaning. Regular power washing actually saves money long-term by preventing the buildup that leads to permanent staining or surface damage.
Not when done correctly with proper equipment and technique. The key is using the right pressure for each surface – what’s safe for concrete can destroy vinyl siding. We adjust pressure, nozzle selection, and approach based on the material we’re cleaning. Vinyl siding gets low pressure and specific angles to avoid forcing water behind the panels. Wood surfaces get treated for grain direction and age. Older surfaces get extra care. The bigger risk is actually avoiding power washing – letting organic growth and grime build up causes more damage over time than proper cleaning ever will.
Most residential properties take 3-6 hours depending on size and condition. A standard single-story home with basic concrete work usually runs about 3-4 hours. Two-story homes with extensive decking, multiple concrete surfaces, or heavy soiling can take a full day. We don’t rush jobs to fit more into a day – your property gets the time it needs for proper results. Weather can affect timing too, since we won’t work in conditions that compromise safety or results. We’ll give you a realistic timeframe when we assess your property.
Yes, we bring everything needed for the job. Our trucks carry water tanks, so we’re not dependent on your home’s water pressure or running up your water bill. Our commercial-grade pressure washers deliver consistent results that consumer-grade equipment simply can’t match. We also carry various cleaning solutions, different nozzles for different surfaces, and safety equipment. You don’t need to prepare anything except moving any delicate items away from the work areas and ensuring we have access to the areas being cleaned.
The terms are often used interchangeably, but technically power washing uses heated water while pressure washing uses cold water. Hot water is more effective at breaking down organic matter, grease, and stubborn stains – especially important for Maryland properties dealing with mold, mildew, and organic growth from our humid climate. For most residential exterior cleaning, we use hot water power washing because it’s more effective and often requires less pressure to achieve better results. This means better cleaning with less risk of surface damage.
We avoid working in rain, high winds, or freezing temperatures for both safety and effectiveness reasons. Rain dilutes cleaning solutions and makes surfaces slippery. High winds can redirect spray and create safety hazards. Freezing temperatures can cause immediate ice formation on cleaned surfaces. We also avoid extremely hot days when possible, as rapid evaporation can leave cleaning solution residue. Maryland weather gives us plenty of good working days throughout most of the year, and we’ll work with your schedule to find suitable conditions for optimal results.
