Your Deck and Patio Deserve More Than a One-Size-Fits-All Pressure Wash
We’re Jet Wash Exterior Cleaning, a family-run business serving homeowners across Madison, WI, and we clean decks and patios based on what they’re actually made of. Wood, composite, vinyl, stone, concrete: each one calls for a different approach. A stained wood deck gets handled differently than bare lumber. Painted surfaces get different attention than aging composite boards. And patios made from stone or poured concrete, including pool decks, follow their own multi-step process entirely.
If your outdoor space has been collecting dirt, algae, or that slippery green film that builds up after a long Madison winter, that’s exactly what this service addresses. Damp conditions and seasonal temperature swings in southern Wisconsin push organic growth faster than most homeowners realize, and by the time you actually want to use your deck, the surface can look years older than it is. We clean that buildup safely and improve the appearance without using more pressure than the material can handle. This is careful cleaning and light surface improvement, not aggressive restoration and not stain stripping.

What Deck and Patio Cleaning
Costs in Madison
The Factors That Shape Your Quote
Deck cleaning starts at $100 and up, and that’s a starting point rather than a flat rate, because no two deck layouts are the same. Your quote depends on several factors that each change the time, care, and technique the job requires:
- Whether the deck is wood or composite, and whether the wood is stained or painted
- Overall deck size, stairway presence, and stairway height
- Spindle condition and how carefully the crew needs to work around them
- How fragile or worn the surface already is, including signs of prior pressure-washing damage like pitting or etched lines
Older composite often needs more caution and more conversation up front about realistic results. Stairs add labor, and surfaces with existing damage may require an adjusted approach before we even start. Most deck cleaning jobs take an hour and up, with larger or more complex layouts running longer.
For patios and pool decks, we quote based on material, square footage, condition, and layout. There is no separate published price range for patio-only or pool-deck-only work, so the best step is to request a quote for your specific surface.
Saving Money with Bundled Exterior Services
When paired with a house wash, a deck or driveway add-on could be priced at even $50 and up, compared to a $150 minimum for a stand-alone driveway job. Natural pairings include deck cleaning with house washing, patio cleaning with driveway cleaning, deck cleaning with fence cleaning, and pool deck cleaning alongside a full exterior wash.
If you’re planning a pre-stain cleanup or a full seasonal reset, bundling makes even more sense. As a general practice across all our services, returning customers receive either complimentary additional services or reduced pricing. No current percentage-off promotion, seasonal sale, or named package is available at this time, but the bundled add-on pricing speaks for itself.
Every Surface
Gets Its Own Playbook

Wood Deck Cleaning
We clean wood decks by applying a cleaner first, then using low to medium pressure to remove organic material. Where it makes sense, we slightly improve the surface of the wood, but we’re careful not to mar it. This is not stain stripping. We don’t strip deck stain as part of standard deck cleaning. The goal is to clean off dirt, algae, mildew, and organic buildup, and where possible, lightly improve the look underneath. If you’re planning to restain down the road, a thorough cleaning is a smart first step. The general guidance is to wait for a couple of rainfalls or give the surface a good hose rinse before applying new finish, so the wood has time to dry and accept the stain properly.
Composite Deck Cleaning
Older composite surfaces are more fragile, and many have already been damaged by past high-pressure washing. We see plenty of decks where the homeowner left marks across the surface with their own pressure washer. We can remove organic buildup and improve cleanliness, but we’re upfront about what we can’t undo. If the surface is pitted or etched from previous misuse, those marks are permanent. We clean composite with low to medium pressure and focus on the best realistic result without making prior damage worse. We’d rather have that honest conversation before work starts than leave you disappointed afterward.
Stone Patios, Concrete Patios, and Pool Decks
Our patio and pool deck process is multi-step: inspection, cleaner application, surface cleaner across the main area, specialized nozzle work on edges and tight sections, and a post-treatment to kill deeper organics. That post-treatment step is what separates this from a basic wash. Homeowners dealing with slippery buildup, darkened organic staining, or grime that keeps returning after seasonal weather changes will notice the difference right away, and the result is a surface that looks cleaner, feels safer, and makes your outdoor gathering space more inviting. For anyone worried about the grass next to the pool deck: our cleaning process is not expected to harm it.
Vinyl Deck Cleaning
Vinyl decking is part of our standard deck cleaning offering. The handling gets adjusted based on the condition of the surface, using the same careful, material-aware approach we apply across all deck types.
What Sets Us Apart for Madison
Deck and Patio Work
We Match the Method to the Material
Every surface type gets its own approach: wood, composite, vinyl, painted wood, stained wood, stone, and concrete. That reduces risk and leads to a noticeably better result than one-method-fits-all cleaning.
Cleaner Goes Down Before the Pressure Comes Out
Our process starts with a cleaning solution before any pressure is applied. Decks get low to medium pressure, not aggressive blasting. This is where inexperienced contractors, past providers, and DIY pressure washers go wrong. They skip the cleaner and crank up the pressure. What you’re paying for here is judgment and restraint, not just equipment.
We're Upfront About Older Composite Limitations
If your composite deck has permanent pitting or etched lines from previous cleaning, we’ll tell you before we start. Organics can usually be removed, but surface damage from past misuse stays. We’d rather set realistic expectations than overpromise.
Clean Strokes, Not Swirl Marks
We use consistent long swipe cleaning strokes to reduce visible marks on the deck surface. That finish-quality focus matters to homeowners who’ve seen what random passes and uneven pressure leave behind.
We'll Walk Away from a Rotten Deck
If a deck is rotten or structurally unsafe, we may refuse the job. That’s a safety decision that protects our crew, your property, and you.
Pool Decks and Hardscape Get the Full Treatment
Our pool deck cleaning runs five steps: inspect, apply cleaner, surface cleaner on the main area, specialized nozzle on tight spots, and post-treatment to kill deeper organics. Each step plays a role in the final result.
Straight Answers from the First Phone Call
We ask the right questions before we show up. What’s the material? Stained or painted? Stairs, spindles, areas of concern? We discuss what we can and can’t improve before work begins, so there are no surprises on service day.
Built for Madison's Four-Season Wear and Tear
Madison’s freeze-thaw cycles, spring rains, and humid summers push organic growth on decks and patios faster than most people expect, leaving a winter’s worth of grime by late spring. Scheduling a cleaning before you start using your outdoor space prevents that buildup from getting harder to manage and keeps wood and composite surfaces in better shape long-term.

How We Clean Your Deck or Patio
Identify the Material and Evaluate the Surface
Everything starts with identifying what we’re working with: wood, composite, vinyl, stone, or concrete. For decks, we also check whether the wood is stained or painted, whether stairs are involved, stairway height, spindle condition, and whether the surface shows pitting, lines, or structural concerns. Rotten or unsafe decks may be declined. We also note whether this is a stand-alone job or part of a larger bundle.
Review Expectations, Concerns, and Site Conditions
Before cleaning begins, we talk through what’s realistic. This matters most with older pitted composite, surfaces with permanent pressure-washing marks, or when a homeowner expects like-new results on already-damaged material. Concerns about nearby grass, landscaping, or future staining plans are all addressed before we start.
Apply a Cleaning Solution to Break Down Organic Buildup
A cleaner goes down before washing to loosen algae, mildew, and dirt so the pressure doesn’t have to do all the work. This pre-treatment supports a safer, more controlled clean on every surface type.
Clean with the Right Pressure and Technique for the Surface
We clean decks with low to medium pressure. On wood, we remove organics and lightly improve the surface without marring the grain. On composite, extra care goes into older boards to avoid overworking already-damaged material. Across all surfaces, we use consistent long swipe strokes to keep the finish clean and uniform.
Detail Hardscape, Post-Treat, and Review Aftercare
For patios and pool decks, we complete the full sequence: inspection, cleaner, surface cleaner, specialized nozzle on edges, and post-treatment. After the job, we review results and remind you that organic buildup comes off but permanent prior damage stays. Pool deck cleaning won’t harm the grass. For wood surfaces you plan to stain, the guidance is to wait for a couple of rainfalls or a hose rinse before applying new finish.

Frequently Asked Questions About
Deck and Patio Cleaning in Madison, WI
Will deck or patio cleaning damage my surfaces?
We match the cleaning method to the material, apply cleaner first, and use low to medium pressure on decks along with consistent long cleaning strokes to help reduce swirl marks and visible lines. On older or previously damaged surfaces, we set expectations before starting so you know what results are realistic.
Can you make my old composite deck look new again?
Not always, especially if the surface has already been damaged by past high-pressure washing. We can remove organic buildup and improve overall cleanliness, but we’re honest when pitting or permanent lines cannot be reversed. Our goal is safe, realistic improvement rather than overpromising.
Can you fix lines left by a homeowner's pressure washer?
Not if the lines are permanent surface damage from incorrect pressure washing. We can still clean off dirt, algae, and organic buildup, but we don’t claim we can undo etched damage caused by excessive pressure. That’s why composite decks need a gentler cleaning approach.
Do you strip deck stain as part of deck cleaning?
No, standard deck cleaning is not a stain-stripping service. We clean away dirt, organic material, and buildup, and on some wood surfaces we may slightly improve the surface appearance. We don’t market this service as aggressive stain removal.
Can you clean a rotten deck?
Sometimes the safest answer is no. If a deck is rotten or structurally compromised, we may decline the work for safety reasons. That protects both our crew and your property.
How do you protect my plants and landscaping during the cleaning?
Before starting, we cover nearby plants, move furniture, and make sure water flows away from garden beds. Our cleaning mix is eco-friendly and safe when used properly. We also rinse everything down afterward so no residue stays on your grass or flowers.
How long does deck cleaning usually take?
Most deck cleaning jobs start around an hour and up. Total time depends on the size of the deck, the number and height of stairs, and how much spindle or detail work is involved.
How much does deck cleaning cost?
Deck cleaning starts at $100 and up. Pricing depends on the material, whether the wood is stained or painted, the size of the deck, stairway details, and the condition of the spindles. We provide quote-based pricing because every deck layout is different.
Will pool deck cleaning kill the grass around it?
No, our pool deck cleaning process is not expected to kill the grass. This is one of the most common concerns we hear, and the answer is simple: your lawn will be fine.
What should I do before my deck or patio cleaning appointment?
Make sure the work area is accessible, clear any furniture or planters from the deck or patio, and point out surface or landscaping concerns before we begin. If you have worries about nearby grass or delicate areas, bring those up in advance. Weather and surface conditions can sometimes affect timing, and on older composite or previously damaged surfaces, we’ll set realistic expectations up front so there are no surprises once the work is complete.
What is the best time of year to schedule deck or patio cleaning in Madison?
Many homeowners schedule in spring or early summer after winter buildup has had time to settle in. It also makes sense before peak outdoor entertaining season or whenever organic growth starts making the surface look dirty or feel slick.
Can you clean my deck before I stain it?
Yes, deck cleaning is a solid first step before staining or other maintenance. After cleaning, give the wood a couple of rainfalls or rinse it with a hose before applying new stain. That helps the surface dry out and accept the finish properly.
What if the weather changes around the time of my service?
Outdoor cleaning can be affected by weather and surface conditions. Timing and workflow may be adjusted when needed to clean safely and get the best possible result.
