Efrain did a great job on our dirty windows. We have divided lites and two stories, so the job was not an easy one, as each window consists of multiple panes which have to be cleaned separately. Efraim arrived on time, worked carefully but efficiently and was done before the estimated time. The windows look great. His pricing was in the middle of the estimates we received. We would use him again. read more

GS Window washing - An example of how clean one of my windows is after Efrain cleaned it. - Window Washing Near Me - San Jose, California

Service person is really nice, but he didn't clean the front corner down drain that I specifically requested. The next very next week's rain still shows blockage at the spot. read more

I contacted Efrain to clean my solar panels. He had the best price and did a great job. He responded quickly through the Yelp app and scheduled the cleaning for the same week I contacted him. While he was on the roof, I asked him to check the gutters since I have never cleaned them before. He showed me pictures of the debris so I asked him to do that while he was here. Nice guy, great price, quick service. Side note about solar cleaning, I didn't think I needed to clean my solar panels, but I saw the output drop on the monitoring app, especially after the California wildfires. So definitely consider cleaning them. read more

Effrain is my guy to go now for all my solar panel cleaning needs. I have 24 panels and he does not charge per panel. If you have only a few, then maybe you can go with those who charges you per panel. At only a fair flat rate, he washed my entire solar panel. He also noticed my broken roof tiles and offered to mend them at another low price. I don't think any others would do it at his price. So I just let him fix my tiles. I recommended him to my neighbors who did roof repair and gutter cleaning as well. Everyone said that his price is very fair. He is prompt, he shows up at the time he said he would and I didn't have to wait at all. This review is way over due. I had my panels cleaned last Oct and I asked him to come back again this March to repair the tiles. And if you are wondering whether a good cleaning would increase the solar production, yes it does. My app showed me that the day before cleaning and the day after cleaning, the increase was about a 20%. The weather /sun was about the same, so I believe it was due to the cleaning. read more

Efrain is A++ ! We just had our gutters cleaned and leaky gutters fixed by him. He was able to schedule a slot quickly, on the day of, he arrived on time, finished the job very well, for a reasonable price. He is a very polite and courteous man too ! And it has been raining like crazy for the past 15 days or more !! It was raining when he did the job.

Efrain was on time and did a fantastic job at a very reasonable price. I have contracted with him to come 3 or 4 times a year. The windows look better than ever before, thank you for the great service read more

Efrain is the bomb!! Gave me the most reasonable quote for windows and came through. I have about 34 windows and paid under $300 for his service! Other quotes began at $330 up to $400 plus, so I thought, "Why not?" He showed up early (7:30 a.m.) and quietly moved around the house, outside first. He had a female assistant who washed the screens and spotted him on the ladder- Once he finished the outside, he entered and resumed cleaning the inside windows & tracks. It took him about 5.5 hours to complete the job and my windows sparkled. My view is a lot brighter now- really!!! If you need your windows done, I highly recommend Efrain. He also will redo screens ($10 each vs the $30 each another company quoted me). In addition, he cleans gutters. So, if you need any of these services, call Efrain. I'm glad I did! read more

I contacted Efrain to clean the gutters in my home. He responded almost immediately and gave me a reasonable quote. He came to do the job the following day and he went the extra mile taking picture explaining to me that my roof was damaged and needed repairs. He explained to me the options I had to hire a professional roofing company or hire him to do the job; since I understood that fixing the roof was something I needed to take care immediately, I also hired him to do the repairs in my roof. I am very satisfied with the job he did and I would strongly recommend Efrain for anything related to roof and gutters. Thanks Efrain for a job well done read more
