Pressure Washing reviews in Mountain View, California

Very pleasant, excellent services.

It was so easy to book my solar panel cleaning.
The company was professional and friendly.
I will call them when I need other work done.

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.

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.

Sion does fantastic work - they are very professional, they are prompt and on time, they do their work quietly and efficiently, and they really have very courteous and professional staff. We had a great experience with them.

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!

Arrived on time and as scheduled. Completed the cleaning of our gutters. Great communication. Very efficient and high quality work. Highly recommend!

They just finished power washing backyard and front hardscape. Did a great job. Very professional. Recommend highly.

These guys came out fast, produced a reasonable quote in a few hours and delivered good quality results. They run a super professional operation (all their gear, communication and technology). Would highly recommend.

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 needed a quick solution to neglected gutters and Slon was on it! Easy and quick bid. I live in Portland and property is on the peninsula. Slon's technician sent me detailed photos of the now-pristine gutters! Great stuff.

Great job by The Slon Team. They have cleaned my solar panels and my pool deck/post backyard fire. Excellent service in both cases. Highly recommend!!

Although Slon does high quality power washing, they are very expensive. This was my second time using them but next time I would shop around. Diamond’s does windows and are certified in power washing at a more reasonable price.

Pleasure working with Slon. Great scheduling and communication and they did a nice job on the pressure washing.

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. .

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.

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 don't spray the dirt into the corners and they'll take it with them" but that didn't 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 didn't 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 would've given them 5 stars if they clean them all!!

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!

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.

Slon did an amazing job in cleaning my driveway, sideyard and backyard. Greg and Alex were very careful in moving plants and furniture away and cleaned everything very well. Highly recommended, and I will use them again.

Slon did a great job with my windows. Unfortunately the crew was unable to reach windows on a very high 3rd/4th floor. The Sales Manager (Ivan) apologized and gave a full refund for the entire job (unprompted). I honestly would not have noticed since the rest of the windows looked great. So five stars for honesty and providing a full unprompted refund even though the job was 90% complete.
