Oscar responded to my call where I explained I needed my windows cleaned asap as I was listing my house for sale. He said they would be here the next day. They showed up on time and ready to work. My windows hadn't been cleaned in 5 years. They did a wonderful job! His price is very reasonable. I called other window cleaning services and didn't even get a call back. I'm very happy with Oscar and his fellow worker. They were very nice and professional. I am definitely using them in the future for my new place. Highly recommend them. read more

I just found out that my partner paid $300 for our two condo's windows to be cleaned. $150 for each condo (small with only 4 windows each) is ridiculous. I was out of town and she contacted these people without asking me WHO I've used in the past. SAVE your money and find someone else. She found them on Home Advisor....keep looking! read more

Had the inside and outside and tracks cleaned at my house this morning. Amazing job and very professional. Highly recommend them.

Oscar returned my phone call seeking an estimate and since it was Mother's Day, he asked if he could call me Monday morning between 11:00 am and 12:00, which he never did. It's not a good way to add new customers by not following up. read more

I was referred to Oscar by a neighbor. I have 20 feet high windows and many window washers refuse to do them. Oscar did a fantastic job!!!! I highly recommend him!! read more

This fellow is unreliable. He cleaned my windows in the past and did a good job however this time around, he never showed. He did call once to tell me he was running late but never even called or showed. Also he did not bother to reschedule. Find someone who is more organized and professional. read more

Had a problem with cracked roof tiles around the solar panel that O's cleaned. His people where the only ones to go up in that area, the panels have been up for 6 years. They claimed they where cracked before they went up there, however; they never notified us of this problem. The way this problem was handled was terrible. They did not look at the problem just said there was no way they could do this. Because of this attitude I would never use them again. Robert Hofmann - North Tustin 92705 read more

Very friendly and thorough service. Oscar and Guillermo did a great job for a decent price. They cleaned the gutters and the driveway. I will very likely use their services again. read more

Oscar is a very nice man. He showed up when he said he would and did a very good job on my extremely dirty windows and patio slider. I would call him back again. read more

One of the best window washing services I've ever used. Oscar and his crew were on time and ready to work. They spent about an hour and a half on my 3000sqft home. They scrubbed and cleaned the windows and screen throughly. Very polite and courteous while understanding my needs perfectly. They did an outstanding job on my windows. They have never looked so crystal clear! I would definitely recommend O's Window Cleaning service. Great prices and Wonderful job! read more

Oscar came right on time and cleaned one of our homes last week. I left him there by himself and he locked it up himself. All was done in an excellent manner. I completely trust Oscar! Then just today he did another home of mine and did all the skylights and all my windows/screens.They all look excellent! I would not use anyone else.Oscar is on a maintenance schedule with my homes and he always comes with a smile and an excellent work ethic. Also his pricing is very fair! Thank you O's Window Cleaning!!! read more

These guys are pros.. they know how to clean windows perfectly. We have 2 story and large high ceiling windows that are not easy to get to.. They were so nice and did a phenomenal job! read more

I just used O's Window Cleaning for the second time and they do an outstandingly job! Our windows are so crystal clear it looks like there is no glass at all. We had a lot of water spots and some Windows and they had a special product that removed the spots completely! I would highly recommend them. read more

An absolute recommend! Oscar and his team are very thorough, professional, courteous, and most important for this kind of work: detail oriented! The windows I needed cleaned are very high (glass goes 20 ft. high) and VERY difficult to get to but they have all the equipment needed for tough jobs. If you need windows cleaned and/or power washing done, these guys are the best. read more

Oscar came and did the windows for my mother's house and her company today. He did an excellent job! Above and beyond our expectations!! He was on time, professional and courteous. He made sure that we were happy with his service before he left. We're going to have him come every month! read more

The best!! They were on time and thorough, our windows look fantastic. I strongly recommend using their service.

O's window cleaning service is as great as it gets. Oscar, the owner of the business, came out this past week and spent most of the day cleaning our home windows. He is friendly, reliable and professional. He kept me apprised of his arrival time by text. His work was excellent, he paid extra attention to detail and his pricing is very reasonable. We are thrilled with the results. We spent literally years trying to find a window cleaning service like O's. If you haven't found the right window cleaning service yet, call Oscar! read more

Don't use Oscar, he's a fraud. He broke my expensive shutter and tried to hide the evidence on top of my marble table. I found it after he left. Of course he was going to take it with him, and not tell me. Obviously he forgot. I had to look for the damage and finally found it behind the couch where you couldn't see it. Before I knew what happened, he took my check and I hired him to come back to clean gutters. He was supposed to be here at 8 am, he showed up at 10 am. When he finally showed, I was gone. He told my daughter a lie that $75 would only cover 50 ft. Actually we had agreed on the phone $75 for the entire house perimeter. Thank God I showed up and confronted him. And thank God my daughter was smart to recognize a scam. read more

Oscar the owner is unprofessional and rude. He sent a worker out to power wash my house. The worker was very professional and did an overall good job, however when he removed the screens from the windows he scratched some of the windows. I called Oscar to express my concern and right away he became combative and rude. He kept insisting that the windows were already scratched and that if he decides to come out to look he will charge me a fee. I would not recommend this company! read more

Look no further if you're in need to have your windows & screens cleaned. Oscar is very professional, courteous, on-time, VERY nice, and did a wonderful job on our windows and screens. I will definitely recommend him!!! read more

I have a condo that needed its windows washed desperately. I called O's Window Cleaning and Oscar and his very nice helper (and I apologize that I didn't get his name) came out and did the inside and out, power washed the patio, and even helped me pull a very deep-rooted plant out of the planter. Very professional, very nice. He lets you know ahead of time if there may be issues (my screens were 27 years old) so there are no surprises. I would highly recommend Oscar. I will be calling him again. read more

By reading these reviews, it looks like I am not the only one who has had a problem with Oscar's Window cleaning service. On April 7th Oscar came to my Covina house and cleaned my windows and screens. The main reason I picked this service because their website clearly stated "Hard Water Deposit No Problem". Well, when it came time to get to the front of my house where the Hard Water Windows were located, Oscar said that he did not have the paste that he needed to remove the hard water deposit. Your job is to clean windows and you do not bring what your jobs requires? I mentioned to him that we had e-mailed at least twice where I specifically noted that my front windows really needed extra work. So, he said he had another job in my area the following week, and he would for sure re-do my front windows. If for some reason he could not come back during the week, that Saturday April 15th he would be back for sure. I totally believed him, and crazy me paid him in full plus extra for the invoice amount, where I should have pro-rated the job. On his invoice copy it too says Job Incomplete, re-do front windows. I have e-mailed him personally and the company several times and never a response. I am sorry I choose this service every time I look through my front windows. read more
