CleanTech Services LLC

The process with CleanTech flowed easily from estimate, Q&A, choice of date/time, to work performance. Andrew accommodated our slightly earlier time, arrived ever so promptly, and turned his attention readily to his work. Afterwards, when asked about his other areas of expertise, window cleaning, he answered what he could and said he would get back with his other responses & an estimate, which he did in very short order. It is a joy to have a tradesman come in who is polite, considerate, competent and efficient. We look forward to having him try out our window cleaning shortly. Good job, Andrew, and thank you.

Excellent, service was efficient and dealing with the companies owner was more than a pleasant experience. Solar panels were left in a bright and clean condition. Will use company now on a regular basis.

Andrew arrived promptly and patiently answered the several questions I had. His answers clearly demonstrated is knowledge of the proper care and maintenance of solar panels that live in the LA basin. His cleaning technique utilizes purified water that is pumped through the handle and soft bristles of his (very) long handled brush. The flow of water is very low so there is no danger of damaging the glass of a hot panel. My panels were cleaned mid day and they are brilliantly clean. Since the water is purified, there is no need to squeegee and there is no residue left behind from detergents. I am very pleased with the results. In addition, Andrew is very personable. As we all know, obtaining home services can be a nightmare...this was a very pleasant experience. I highly recommend CleanTech Services. I have asked Andrew to put me in his system for visits every 6 months.

Andrew arrived promptly, started working immediately, and finished in a couple of hours despite the fact that my house has a lot of Windows. Very cortious and thorough, Andrew did a great job while educating me on several aspects of Windows construction and the cleaning processes he was using. Will call him again next time an will recommend him to my neighbors.

Watsons Window Washing came originally to wash our solar PV panels. What appealed to me was the fact that they used no detergents or other chemicals which would have been unfriendly to the seals on our panels and to environment in general.Andrew, who did the work arrived exactly at the time of his appointment, went immediately to work and did a really great job of cleaning our 42 panels. I was so impressed with his work I asked him if he could wash the windows in our home. He checked his schedule and said he could fit it in. He proceeded to clean our windows and window screens using the same treated water he had used on our solar panels. The windows and window screens have never looked better. He did the job quickly and left virtually no sign he had ever been here other than the sparkling windows and solar panels.I now plan to use their service on a regular basis.I would not hesitate to recommend them to anyone.

They guy who came over was wonderful, personable and did a great job for a reasonable price. He cleaned all my windows and he was fabulous. He did all the work by hand and he was not an average window washer. He used purified water and he was very exact in what he did.

Very satisfied. The guy knows his job and he is very meticulous.
