Easy to schedule and work with. Courteous and customer friendly. Not the least of which is they do an excellent job and they are VERY careful not to damage anything. They are not cheap but sometimes you get what you pay for and this is one of them!

The company was very responsive when I initially emailed them for a quote. Once I had the quote and agreed to the service, again they were very quick to respond and set up an appointment time. My appointment was set for 11am. They arrived at 11am. The power washing turned out better than expected. I will definitely use them again and highly recommend them to anyone who needs their service.Thanks,Don Tsukamoto

Just an update...Ivan and Sergey came back today to clean the dirt on the side and corner of my house! This tells me that customer concerns are really important to them, I appreciate that. Thanks Ivan and Sergey for coming back and cleaned the dirt on the sides of my house. After what they did today, I will for sure be using them again and will also refer them to my friends and family. 3 stars to 5 stars!!!Alex and his crew did a good job cleaning my roof. Now my house looks like just got a new roof as it is so clean!! Why only 3 stars? Well, in their website says, they just dont spray the dirt into the corners and theyll take it with them but that didnt happen, they just sprayed it to the sides and corners of my house. Now, there are so many maroon colored dirt round my house. Website also said, they collect all waste water, that didnt happened either. Will I use their service again? probably not. Leaving those dirt to the sides/corners of my house was a big no no for me. I wouldve given them 5 stars if they clean them all!!

I had an excellent experience with SLON Power Washing. I manage a property in Los Altos and the tenant found a SLON flier. He wanted to have a power wash for the walk ways to reduce the chances of his 99 year old mother slipping on mossy bricks. Neither of us had ever used SLON prior to this experience. SLON were easy to contact, replied quickly, and arrived promptly for their cleaning appointment. Id never had a power cleaning before and thought SLON did an excellent job. The tenant had previous experiences with other power washing establishments and he said that he thought SLON did the best out of all the other power washers he has tried. I will use them again and recommend them to others.

Service was incredible! The technicians arrived in time, cleaned the floor and tiles of the entrance and even cleaned a bit the front yard. Really good service.

The technicians were very thorough, efficient, and pleasant to work with. I will definitely use them again.

The work that SLON performed at my residence was phenomenal. It was a big, dirty job and hadnt been cleaned in over 10 years. They bought the cement back to looking new. It is awesome. They went over and above my expectations. They moved items that were in the way to make sure to thoroughly clean. They raked up leaves in the pool area so they could clean under them. They even disposed the leaves in the garbage cans. They even cleaned some tables and chairs. Very professional and kind. I will definitely be hiring them again in the future.

Ivan from SLON is very responsive. Process was quick and easy. Ivan scheduled a tech to come out and look at our property. Oleg (sp?) came out and we walked around the house and discussed their services. I wanted a company that would NOT be using chemicals as we have a pet. SLON doesn’t use chemicals - just water, pressure and heat. The team arrived on time and were very professional. I would highly recommend SLON to any homeowner looking for exterior cleaning services.

I am very pleased with the results: the gutters looks as good as new, free of debris, the roof is cleaned. The crew came in time, well equipped, dressed professionally. Communication and scheduling of the service was quick and easy. This is not my first experience of working with SLON, and definitely not the last one. I will recommend SLON for all my friends and clients. Thank you so much!

Slon came to help us with a water filter installation. Oleg was super attentive to details and asked for my participation only when couple of decisions had to be made. Communication was clear and simple. Work was done fast and accurately. Will definitely call Slon again! 👌

Team were willing to accommodate a last minute booking. They arrived on time, were professional and friendly, did a wonderful job with some very dirty concrete, aggregate paths and retaining walls. Would definitely use again.

Ivan and his team were great! I hired the company after seeing one of their beautiful looking trucks driving on the highway. With a little research I found that they were the best fit for the job. I hired them to remove years and years of chewing gum buildup on the front entrance of a 24 hour fitness gym. The results were amazing! They arrived on time and wasted no time to get to work. His team was extremely professional and courteous towards our members who exited and entered the building. Will definitely do business with his team again and will help spread the word to anyone looking for some professional cleaning. Thanks Ivan! 👍

Incredibly pleased...SLON cleaned 20+ years of build-up from our entry walkway and driveway...it looks brand new. I wouldnt hesitate to use them again, and to recommend to anyone looking for cleaning services.

Ivan and his team arrived on time and quickly set up their machinery. They were very professional and neat in their appearance. They accomplished the job well within the stated time. The finished results were amazing. The brick patiowpatio very dirty and covered with black mold. It looked like new again once they were done. Every thing was handled very professionally. Im very pleased with the results

I can only say that I am very pleased with the work they have done on our property. Very professional people and I really like the way they work. They immediately responded to a request to come give me an estimate and we immediately scheduled a job. Attached picture showing how it was before and how it is now. Price very reasonable. I recommend them 100%. Well done.

They cleaned our business sidewalks and it came out perfect. I would use them for all my projects.

Ivan’s team did an excellent job cleaning our aggregate patios but also suggested that they would clean the walkway on the side of the house in addition for the same price. The work was amazing and the end result was as well. They were on time, very efficient, and very courteous. I would highly recommend the Slon Company. I reached out to Ivan prior to the work being done and he was very responsive and professional. I’m so glad I found them!

They came out within 24 hrs (in the pouring rain) to give a quote and get us scheduled. They showed up on time, worked promptly, and the results speak for themselves. It was everything you expect .... but seldom get in a service. They are our go-to resource now.

Slon power washing was such a great group to work with. WE had only one spot to redo and the crew came out and took care of it. Owner was very pleased. They came recommended from another commercial firm.I would definitely recommend them. IVAN WAS ESPECIALLY WONDERFUL.- A TRUE PRO. .

Slon did an awesome job cleaning up some oil that had been left sitting for a long time. I appreciated their professionalism and honesty. Right away, they admitted that even they may not be able to deal with the problem due to the amount of oil and how long its been there. They offered to come show me a sample of their work, and only proceed if I was satisfied. They brought out two trucks and four technicians just for the demo. When they went to work, it quickly became clear how effective the cleaning would be, and the end result exceeded our expectations. Would 100% recommend their services for your business or home.

Good service, on time, good value, nice guys, observed protocol. Couldn’t ask for more.

I have old bricks that get very mossy over the winter. Ive had damage to these bricks from previous pressure washes. The Slon team was very careful, thorough, and communicative. This is the best the bricks have looked after cleaning. I will use them again.

Our concrete patio sparkles like glass. It’s cool to see the sun glistening off of it. Thank you Slon for such an amazing job.

Excellent service.

Patios of pavers and cement curbs all look brand new. Excellent job!!!!

Excellent service and professional results. Guys are punctual and go above and beyond of what was discussed. I highly recommend the company for all your outdoor cleaning needs.

This guys are awesome! Cleaned everything i asked and even more. Before Slon i had a very bad experience with other power washing company. But now i know what professionalism means.

The guys did an excellent work! My backyard looks like new. Highly recommend!

They are not just cleaned my roof. After the cleaning, they also carefully remove all the left over on my yard. Really appreciate!

These 2 men were professional attentive and very friendly.

We wanted to give a great reference to Slon Power Washing (slon.org). They did an outstanding job for us and we highly recommend them. They provided a deep disinfecting and power wash cleaning for our outside area of our home. They power washed our driveway and all our outside and interior walkways. Ivan, the sales manager did a great job understanding our needs and provided a very reasonable proposal. Alex and Oleg came out to do the work. They were timely, worked hard to understand our particular needs and interests, and performed a very high quality cleaning. We recommend them highly. We will have them out again within the year. If you want to get any type of power washing and disinfecting for a home or commercial location, just go straight to them. They will get it done well and for a very reasonable price. The before and after results for us were excellent – we now have such a clean and brighter feeling around our home.Stu and TerryMay 14, 2020

Night and day! Our stone steps look so much better now in our home! Guys were super professional and did a good and quick job!

Very professional job completed on my driveway! I couldnt believe my eyes after seeing how clean they made my driveway! All around amazing disinfection and cleaning services provided by SLON. Completely unparalleled service.

They were prompt and efficient! Afterwards our driveway and patio sparkled and the service was great. Highly recommend

Very easy to work with and did a great job. Would recommend for pressure washing job at your home.

Friendly, timely, and professional service. These guys know how to do the job right! Their tools are very powerful, and they ensure the best result.

Everything was cleaned very quickly and thoroughly. Super accommodating as well.

Definitely a worthwhile service! Did a great job on a driveway and wooden patio for our townhouse.

These guys provided great service. All the stains are gone from the driveway now.

Outstanding
