Denver’s dry, high-altitude climate treats a deck very differently than the coasts do. Instead of the mold and algae that take hold in wetter places, the real culprit here is wind-driven dirt, dust, and storm debris that settles into the boards and grinds into the surrounding surfaces season after season. The high sun and blowing grit work that grime deep into the grain, well past where a garden hose can reach.
That’s the exact grime we lift. Our crew cleans decks, patios, and the whole patio area with a gentle, eco-friendly, non-destructive process, using customizable pressure that stays safe on wood, composite, and cedar. At Platinum Pressure Washing, we’ve cleaned these surfaces across the Denver area for years, and the goal is always the same: pull the embedded dirt out of the surface without harming the material underneath it.
Ready to get your outdoor space looking right again? Give us a call at (303) 931-7300 and we’ll talk through your deck or patio.
Whatever your deck or patio is built from, we adapt our customizable, non-destructive process to that specific material, so the surface gets cleaned thoroughly and nothing gets damaged along the way. If your patio is a poured or paver surface rather than a deck, our concrete cleaning covers that flatwork with the same eco-friendly approach.
We clean natural wood with a gentle scrub and eco-friendly soap at a low, safe pressure that lifts embedded dirt without gouging or furring the grain. Because our pressure is fully adjustable, the process stays non-destructive on real wood, pulling the ground-in grit and storm debris out of the boards while leaving the grain intact.
Composite boards get the same eco-friendly product and a soft, low-pressure approach that clears surface dirt and ground-in grit without marring the manufactured finish. There are no harsh chemicals involved, so the material stays safe throughout the clean and the color comes back without any risk to the coating.
Cedar is the softest of the three, so we dial the pressure down further and let the eco-friendly product do more of the work. That keeps the clean gentle on the wood while still lifting the dirt that has settled into it.
A clean surface is the baseline. Here is what actually makes the difference when you have us handle your deck and patio.
Our pressure is fully customizable and gentle enough to be safe on exterior surfaces, low enough that you could hold your hand in front of the wand, which lets us rinse surfaces most crews wouldn’t dare pressure wash. On a deck, that control is everything. It means we can bring a real clean to softer woods and finished composite at a pressure that protects the boards instead of wearing them down.
A deck or patio sits right in the middle of your landscaping and where your kids and pets spend time, so what we clean with matters. We use eco-friendly products safe enough that your kids, pets, and neighbors can walk right by while we work, with no harsh chemicals and no killed landscaping. The grass, garden beds, and plants around the patio stay protected from start to finish.
Most crews clean the floor and stop there. We treat the patio as a whole space, so the surface and everything sitting on it come away clean and the area is genuinely ready to use again, not just walkable. If your outdoor space wraps around a pool, our pool deck cleaning gives that decking the same careful treatment.
It starts with a free estimate. You call or request a quote, and we talk through the deck or patio: the material, the size of the space, and what’s sitting on it. We reassure you up front on pressure and safety, because that’s the first thing most people ask about. Pricing is scope-based off our standard tiers and confirmed with a walkthrough where the job calls for it.
Once you’re ready, we book the job and send confirmation. Scheduling is flexible around what works for you. All of our work is weather-permitting, so if we’re looking at below-freezing temperatures or a storm, we’ll reschedule for safety to make sure the result holds up.
Our crew arrives and starts with a thorough walkthrough of the space. We protect the surrounding grass, plants, and landscaping, hook up to water, and confirm the scope before anything gets sprayed. The whole process is kept low and safe specifically so the greenery around your deck comes through untouched.
Now the actual cleaning. We adjust the pressure to the material in front of us and move across the space methodically. This is also the step where the patio furniture, chairs, and tables get cleaned, using our customizable-pressure machines and eco-friendly product so nothing in the space gets skipped.
We finish with a light rinse, pushing water and lifted dirt away from the clean surface so no residue or runoff is left sitting on your deck.
Before we consider the job done, we walk the finished space with you and document the before-and-after where it applies. The invoice follows only once you’re happy with the result.
Deck and patio cleaning is priced by the scope of the job off our standard tiers, so the final figure depends on the size of the space and the condition it’s in. A job minimum applies, and things like heavier soiling that needs extra passes or trickier access can shift the number. Here’s how the tiers break down.
A couple of ways to bring the cost down:
We stand behind every job with a satisfaction guarantee. If you're not happy, we'll come back as many times as it takes to make it right, because the customer is number one. That applies to every deck and patio we clean, with no fine print.
We carry insurance and back our work, so your property is protected while we're on the job. Your deck, patio, home, and the landscaping around them are all covered from the moment we arrive to the moment we finish.
Not when the pressure is matched to the wood. Splintering happens when a crew runs one high setting across every board, and older or weathered decks are the ones that suffer for it. We start low, test how the wood is holding up, and only use as much pressure as the surface can take, letting the eco-friendly product loosen the dirt so the water doesn’t have to. Soft woods and aged boards get the gentlest setting of all, which is how a deck comes away clean without a raised or fuzzy grain.
Once a year or twice a year is plenty for most Denver-area properties. Decks and patios here mainly collect wind-driven dirt and storm debris, and we won’t push a recurring schedule you don’t need. We’ll advise you honestly at the estimate.
Yes, and we take a couple of steps to keep them that way. Before we start, we wet down and cover the garden beds and plants closest to the work so nothing gets a concentrated dose, and we clean with an eco-friendly product instead of bleach. You don’t need to move pets indoors or keep the kids off the lawn on our account, though many people like to be nearby to see the results come in.
Not necessarily. As long as we have access to the deck and patio area and a water source, we can complete the job. We’ll arrange a before-and-after walkthrough or sign-off where possible so you can confirm you’re happy with the result.
Your estimate is free and comes with no obligation. Whether you’re getting the outdoor space ready for a Denver summer or you’re just tired of looking at a grimy deck, we’ll take a look and tell you exactly what the job involves. Call us at (303) 931-7300 and we’ll get your deck and patio on the schedule.
