Expert Deck Cleaning That Restores
What Baltimore Weather Takes Away
Between the Chesapeake Bay humidity, the dense tree canopy in neighborhoods like Roland Park and Homeland, and the tight rear lots behind Baltimore’s rowhomes, outdoor wood and composite surfaces take a beating. Mold, mildew, and algae root deeply into deck boards faster here than in most markets, and the grey, slick buildup that follows is more than a cosmetic issue. Left alone, it breaks down wood fibers and shortens the life of the surface underneath.
Here at Baltimore Pressure Washers, we treat every deck cleaning job as surface restoration, not just a rinse. We clean wood, composite, and cedar decks, along with fences and pool decks, using a chemical pre-treatment and board-by-board pressure washing process refined through years of daily fieldwork.
If your deck has turned grey, feels slick underfoot, or is covered in green and black staining, call us at (443) 531-6660 or request a free quote online. We will walk you through what to expect before any work begins.

Why Baltimore Homeowners Choose Us for Deck Cleaning
Board-by-Board Precision
We follow each board individually rather than running wide passes across the surface. This eliminates the visible banding and striping that homeowners notice as soon as the deck dries.
Chemical Pre-Treatment That Kills Growth at the Root
Every job starts with a chemical application that kills biological growth at the root before the pressure washer ever touches the surface. This is why our results last longer than a rinse-only approach.
Adjacent Siding and Windows Rinsed as Standard
We protect the rest of your home while we work. Overspray and dirty water are rinsed off all nearby siding and windows before we leave, at no extra charge.
One Proven Process for Every Surface Type
Wood, composite, cedar, fence, and pool deck surfaces all receive the same chemical-and-pressure sequence. There are no service gaps and no surprises when it comes to difficult materials.
Surface Restoration, Not Just a Rinse
We frame every deck cleaning job as restoration because that is what the results deliver. UV damage, weathering, and years of biological buildup are removed to reveal the original surface underneath.
Backed by Nearly Three Decades of Hands-On Experience
We have cleaned thousands of decks, fences, and pool decks across every material type and condition. That volume of work means we have seen and solved every challenge Baltimore's climate puts on outdoor surfaces.

How We Clean Your Deck, Start to Finish
1
Clear All Loose Debris
We start by clearing the entire deck surface with a backpack blower. Leaves, pine needles, dirt, and organic material are removed from the deck boards, between board gaps, and from under handrail sections before any liquid is applied. This prevents the pressure washer from driving loose debris into the wood grain.
2
Apply Chemical Pre-Treatment
A sodium hypochlorite and detergent solution is applied evenly across the full surface using our soft wash system. The solution dwells on the surface long enough to penetrate the wood grain and break down mold, mildew, and algae at the root. The chemical does the heavy lifting so the pressure washing step can remove everything it has loosened.
3
Board-by-Board Pressure Washing
This is the step that separates professional results from amateur ones. We use a handheld pressure wand and follow each individual board across its full length, using the natural gaps between boards as boundaries for every pass. When passes overlap on wood or composite, the overlapping zone gets hit twice, creating visible banding: darker stripes where passes overlap and lighter stripes between them. Our board-by-board approach eliminates that entirely. We use a handheld wand rather than a rotary surface cleaner because decking requires directional, controlled pressure along the grain.
4
Handrail and Step Detailing
When handrails and steps are part of the scope, each one gets individual attention. The wand is worked around every spindle and baluster, and both risers and treads on each step are cleaned with the same board-by-board method.
5
Rinse Adjacent Siding and Windows
Dirty water and chemical mist reach nearby siding and windows during the cleaning process. We rinse all affected surfaces as a standard part of every job so the rest of your home looks just as good as the deck when we finish.
6
Final Rinse and Inspection
The full deck surface receives a final rinse to clear any remaining residue. You inspect the completed work before we process any payment.
Honest Deck Cleaning Pricing,
No Surprises
Most deck cleaning projects fall between $250 and $800. A smaller deck with standard soiling and no handrails will land closer to the $250 minimum, while larger decks with multiple handrail runs, step flights, and heavier biological buildup will approach the higher end.
The factors that influence your final price include:
Most jobs take between 2.5 and 5 hours depending on size and complexity. When you combine deck cleaning with a house wash, roof cleaning, or window cleaning on the same day, we offer 5–10% off each service.
Geographic proximity between jobs can reduce cost by an additional $20–$25.
Every estimate covers the full scope of work, service-day expectations, and transparent pricing.

Frequently Asked Questions
Is the process the same for wood, composite, and cedar decks?
Yes. Every deck gets the same cleaning sequence: debris removal, chemical pre-treatment, board-by-board pressure washing, overspray rinse, and a final rinse. The material type does not change the process.
Do you clean fences and pool decks the same way?
Yes. Fences and pool decks follow the same process and pricing structure as standard deck cleaning. All surfaces are treated with the same chemical application and pressure washing technique.
How much does deck cleaning cost in Baltimore?
Most projects fall between $250 and $800. Your price depends on square footage, number of handrails and steps, material type, and the severity of staining or biological growth. Contact us for a detailed written estimate.
How long does a typical deck cleaning take?
Between 2.5 and 5 hours, depending on the size of the deck and complexity factors like handrails, steps, and staining severity.
Is there anything that would prevent you from cleaning my deck?
We clean every deck regardless of material type, surface condition, or access.
What is wood restoration?
Wood restoration is the same process as deck cleaning. We treat every cleaning job as surface restoration because the goal is to bring back the deck’s original appearance by removing years of environmental buildup, biological growth, and weathering.
Can I bundle deck cleaning with other services?
Yes. Combining deck cleaning with a house wash, roof cleaning, or window cleaning on the same day qualifies for 5–10% off each service. Contact us to build a custom quote.
Do you guarantee deck cleaning results?
We use an inspect-before-bill approach. You review the completed work and confirm you are satisfied before we process any payment. That inspection is our quality assurance on every job.
Will the cleaning damage my siding or windows?
No. We rinse all adjacent siding and windows of overspray and dirty water as a standard part of every deck cleaning job. Your home’s surrounding surfaces are protected throughout the process.
How often should I have my deck cleaned?
That depends on your property’s specific conditions: tree coverage, shade, moisture exposure, and how quickly biological growth returns. In Baltimore’s climate, most homeowners benefit from cleaning once visible staining or slick buildup appears, which typically means annually or as conditions warrant.
