By Professional Landscapers
Seattle’s wet climate quickly covers outdoor surfaces in slick moss, algae, and grime. Our professional pressure and soft washing services use material-safe pressure and eco-friendly solutions to deep-clean your property without causing surface wear.

Why Choose SSL for Pressure Washing
Full-Service Landscaping Company
Professional Equipment
We use commercial-grade equipment designed to handle residential landscape cleaning efficiently and consistently.
Our equipment gives us the pressure, water flow, and mobility needed for a wide range of outdoor surfaces.
Sustainable Practices
Sustainability is our middle name. We use biodegradable cleaning solutions that are safe for soil and plants. We apply them thoughtfully and protect surrounding elements and the landscape.
Attention to Detail
Every property has its own combination of materials, aging conditions, and landscape features.
We evaluate the surface before cleaning so that we can adjust our technique accordingly.
Expert Landscapers
Our teams work with plants, lawns, irrigation, and hardscapes every day. We understand how outdoor surfaces integrate within the landscape around them.
That experience helps us approach pressure washing as part of the whole property.
Is Pressure Washing Right For Your Surface?
Pressure Washing vs. Soft Washing
Certain surfaces need a gentler hand. For these, we adjust pressure, distance, and technique, testing a low-key area first whenever a material calls for it.
Pressure Washing: Uses focused, high-pressure water to strip away deep-set grime, oil, and heavy contaminants from durable flatwork like concrete and stone.
Soft Washing: Uses low pressure combined with specialized, eco-friendly cleaning solutions to safely dissolve organic growth, algae, and mold on delicate surfaces.
If high pressure risks causing wear or damage, we pivot to soft washing or specialized treatments to deliver a flawless clean while keeping your property and landscaping protected.
Our Assessment Process
Before applying any water, we evaluate four key factors:
- Surface Material & Age: Ensuring structural integrity before cleaning begins.
- Current Condition: Spotting hairline cracks, loose mortar, or fragile finishes.
- Type of Buildup: Matching the cleaning agent to mold, mildew, oxidation, or grease.
- Surrounding Landscape: Protecting plants, lawn turf, and runoff zones throughout the process.

Sustainable Services
Protecting Landscapes While Cleaning
Seattle sits close to water, so we treat every surface with that in mind. What runs off a driveway or a deck eventually reaches a creek, a lake, or the Sound. At Seattle Sustainable Landscapes, sustainability influences the way we approach every part of our work.
Biodegradable detergents
We choose cleaning agents that break down safely, keeping harsh chemicals out of your yard and Seattle’s waterways.
Thoughtful Water Use
Commercial-grade flow control allows us to maximize cleaning power while minimizing overall water consumption.
Controlled Water Pressure
From aggregate concrete to cedar siding, we dial in the exact PSI needed to lift buildup without risking surface wear.
Care Around Plantings
We treat surrounding greenery with care, actively protecting nearby turf, delicate planting beds, and irrigation systems from overspray and runoff.
One-Time or Seasonal Service
Surface Care That Fits Your Routine
Whether you need an intensive one-time clean or ongoing seasonal upkeep, our Seattle pressure washing services adapt to your property’s cycle.
Book us for a focused, single-day wash to strip away winter moss, or bundle it directly with our planting, irrigation, and landscape care services. By combining hardscape washing with your general yard cleanup, your entire outdoor space stays consistently maintained, safe, and welcoming year-round.
Spring
Pressure washing helps refresh patios, pathways, driveways, and outdoor living areas after the stormy months.
Summer
Keep entertaining spaces clean and ready for outdoor living, gatherings, and time in the garden.

Clear accumulated dirt and organic buildup as your landscape transitions into the wetter months.

We are so happy we found this great company to help us completely revitalize our outdoor escape! The bid, design, & build out process was efficient, fun, and very timely. The whole team starting with Ray who did a great job with the bid, and then Adrianna who built out a beautiful design and was very collaborative throughout, to the entire work crew were simply a pleasure to work with at every step. They came in right on budget and we are simply thrilled with the finished product. I highly recommend this company for anyone looking to take their exterior space to the next level and have a lot of fun along the way. Thanks SSL!

I worked with Seattle Sustainable Landscapes for quite a few projects! A new fence in the back yard | A new drip line irrigation | New plants, mulch for the front and back yard | New stone path way between the front and backyard | Improvements to an existing retaining wall + patio.
Seattle Sustainable Landscapes completed all projects quickly, and everything looks amazing. I’ve continued to work with them for irrigation winterization as well as yard maintenance! I’d highly recommend them for any outdoor project you might have!

SSL was great to work with — they dug up a bunch of sod in our yard, ground down a few stumps, hauled in 10 yards of compost, and helped plant a few trees. Their quote was reasonable and the work was completed on time.
Alex Huelskamp
Johanna was insightful about recommendations for yard clean up. Gustavo, and Manuel were kind, mindful, and hard workers. We’re thrilled at how nice the yard looked after their work! 10/10 recommend.
Alex H
Great experience. Here’s what I appreciated:
- The team was responsive, timely, and did what they said they would do.
- The designers were very easy to work with and accommodating of our needs/requests.
- The whole process moved smoothly and quickly from consult -design – start date.
- Overall, things look great. They basically ripped everything out of our yard, laid down new hardscape, and replanted. All at a reasonable price.

They helped transform my overgrown yard to a beautiful space. So pleased with the work. No weed was left intact.
Shirley Stone
I had a small house built on my daughter’s property behind her house for me to live in. The people who built the house left a big and precarious yard. We hired the Seattle Sustainable Landscapers to give me a walkway and growing area. It turned out beautifully. They were very easy to work with, on time, and understood my vision. Thank you so much!
Leslie Hamilton
These folks were incredible. Very communicative from pre-planning through finish. They took my yard from total overgrown disaster to useable, enjoyable and easy to maintain. They listened to what I wanted and offered great ideas on how to make it happen within my budget. The planning process was easy and thorough and the team that did the landscaping was amazing. They worked so hard and got so much done much faster than I anticipated. 10/10 would recommend. I am already planning to hire them again for my next landscaping job.

Seattle Sustainable Landscapes did an outstanding job!
I had a flower and shrub garden installed along with an automatic irrigation system, and the entire experience was fantastic. The team was professional, knowledgeable, and really listened to what I wanted. The layout looks beautiful, the plants are thriving, and the irrigation system works flawlessly—so convenient and well set up. I’m thrilled with the results and would absolutely recommend them to anyone looking to upgrade their outdoor space!

My experience with Seattle Sustainable Landscape was excellent. Adrianna managed the landscape design, and Todd oversaw the irrigation. Both were highly knowledgeable in their respective areas and did a great job addressing any issues that came up throughout the process. I’m very happy with the outcome of the project and would gladly use the Seattle Sustainable Landscapes again for future services.
