You have to be impressed when Corey shows up with his hand built trailer which is designed and engineered to provide a fully self contained service for his customers. Very cool. Add to that the skill he used to clean my two story house with a fragile red tiled roof - well he's a five out of five in my book. Thanks for the great job Corey! read more

Crystal Clean was at our house this morning to clean all the windows on the first and second story and did a wonderful job. Corey is a perfectionist and is very detail oriented. He cleaned the windows inside and out, cleaned the screens, cleaned the tracks, and even all the window sills. Corey and his assistant were nice to have in the house and a pleasure to work with. Highly recommend Crystal Clean Window Cleaning. read more

Corey did a great job getting rid of spider webs and wasp nests on our very tall porch. Satisfied!

Corey and his team are the best! We've used them 5+ times (and my mom has too) for windows and solar cleaning, and the results are always perfect. If you ask, they'll even take down spider webs, and one time Corey went above and beyond to bleach-spray my pergola when I couldn't reach it. Professional, kind, trustworthy, and detail-oriented--I'd trust them in my home even if I wasn't there. Highly recommend! read more

Corey did a great job cleaning our two front bay windows. Missed his original appointment but made up for it by cleaning all of our windows and honoring his original bid. read more

This business did an excellent job. The issue was they have one person quote the job and a crew come do the work. In between the quote and the job being done, we cleaned our house solar panels ourselves so did not have them clean those panels when their crew arrived. Because it was on their quote, they thought we didn't pay them. But the work was never done. The owner still believes they did this work ( they didn't). Now they won't work for us. Extremely unprofessional considering, all they had to do was call us and communicate , but they didn't. We pride ourselves on paying for work received. I would highly recommend their work, just be clear ahead of time, that the bid and/ or changes are clear. read more

We have had owner Corey Byler clean our windows at least 3 times here in Paso Robles. Corey does a great job, works hard, the windows sparkle when he's finished. He's prompt, respectful of our space, and a perfectionist. He works with his son who is also a perfectionist. I will continue to use him every time I want "crystal clean" windows! read more

Just had Corey & crew clean our windows last week. What a joy! I felt very comfortable with Corey from the get-go. The estimate was a breeze and so was getting on his schedule to do the work. They showed up on time on the date agreed upon and did a thorough job on the windows, screens, and frames. They even cleaned our solar panels. I highly recommend Crystal Clean A1 WIndow Services and will definitely call them next time our windows need cleaning. read more

Review removed!!!! One of the workers had Road Rage and flipped me off. Very unprofessional! read more

Today we had Crystal Clean A1 clean our windows for the 4th or 5th time. As always, the job was excellent. Corey and Zach arrived right on time, and within an hour, all of our screens and windows sparkled. We are always very pleased with the job they do. read more

Corey & Zach and their team are AMAZING!! I gave Corey a call to ask for an estimate. He came within a couple of days and gave me a fair quote considering I have very high, hard-to-get-at windows in my townhome. (A couple of other companies I called couldn't get to me for 3 weeks.) They called to let me know when they were coming and asked if it would be ok if they arrived early. Seriously? Our windows had not been washed for 3 years so they were really dirty. They cleaned the windows, tracks and screens very, very thoroughly. They even checked their work before they left and asked if we were satisfied. They were very nice and professional. I will definitely use them every year. It is so nice to be able to look through sparkling clean windows! Don't hesitate to hire them, they're very good. read more

They do a good job cleaning windows but are much too expensive. They also do gutter cleaning. Their price went up 50% this year over last year. Also, they didn't clean the downspouts so the gutters overflowed and when I asked them to clean them they wanted to charge me all over again. Be warned. read more

This is the 3rd time Corey and his team did my windows. Every time they have been courteous, timely, and professional. I have been happy with the job each time. Definitely recommend them. read more

I hired Crystal Clean A1 Window Services to clean out the gutters on my 2-story house. The service was prompt and I was told me my gutters were cleaned out and water was flowing the next day, however I wasn't home to see what all they did. Roofers came later that week to look at the roof for seasonal maintenance and threw down sun-worn parts from a kite that were inside the gutter on the rear of the house. Based on this, the gutter cleaning job was obviously not done thoroughly. read more

We have a house with Spanish style cement roofing and it was very dirty. We bought the house a year ago but it was built in 2000 and had never been cleaned. I called A1 window service and they were able to come out and power wash and clean the roof. My husband was convinced it needed replacing but after the cleaning it looks 100% better, and saved us a ton of money. I highly recommend using Crystal Clean A1 window services. The gentlemen that came out were very nice, professional and they were done within a few hours. Thanks!! read more

This company is excellent! They were professional, courteous and did a great job washing my windows. I'm really impressed with how well they cleaned the screens. I will definitely use them again! read more

I'm going to add to all of Corey's glowing recommendations. I don't know how I lived without Crystal Clean A1 cleaning my windows before--but I will never go back. His crew shows up on time, and is extremely professional and careful (I admit to a little hyper-anxiety over my marble floors). They quickly had my screens and windows so clean they disappeared (sorry birds, look out)! They got all of the cat nose prints off the windows AND got paint off left behind by the builder that I'd resigned myself to living with after my failed attempts at cleaning. This was my first window cleaning (but definitely not my last), but they've cleaned my solar panels before: that resulted in a ten percent increase in production (amazing, right?). If I can post some pictures I'll try to show how clear and clean the windows and screens are, and a comparison of my solar panels vs a neighbor's. read more

Great job, fast response to inquiries and very professional! I highly recommend this company!

They were on time and did a great job. Very nice crew. Our windows hadn't been cleaned in a long time so there was extra sticky "gunk" and they got it all off. Highly recommended!! read more

Fit me in just before the holidays at the last minute. They have a great system, did a killer job on my windows, in/ out, screens, tracks. Would highly recommend! Fair price read more

Corey Byler and his crew do a great job. My windows look wonderful and the price was reasonable. It was done quickly and efficiently; they even came back to help me close some blinds that were too high for me to reach. I would suggest strongly that you give them a try. I have lived on the Central Coast for many years, and have used several different services. They were never that good, so I kept looking; Crystal Clean with Corey is by far the best, and now I dont plan to look any further!!! read more

Nice work, fast and clean services. Both Corey and his son spent a lot of time at our property.

Corey and Zac are fast, efficient and nice. Our windows are clean and shiny. Highly recommend this team! And our solar panels are at 100% performance. read more

These guys were the worst. They did so much damage to our house and a terrible job on the windows. They broke the plastic framing on the French doors, not once, but twice. They knocked the sliding door off the track. They broke one of the venetian blinds. On top of that, knowing that our windows were "foggy", I spoke to him before hand about getting them clean. He assured me that he could, with special grade steel wool and a cleaning product. He cleaned much of the glass, but it is so patchy, spots were just missed. I confronted him on this before he left, and was told the glass was etched and there was nothing he could do about it. Sorry, this is so patchy, that simply is not the case. He just missed spots. Absolutely horrible. read more

I picked Corey off the internet, using YELP reviews. He and his assistant did an excellent job on my windows. He is replacing my torn up screens and knows a lot about windows. On top of all this he is a super trustworthy and hardworking guy. read more

Wow! Called Corey yesterday and now I'm looking at my very clean windows! I know that can't always happen, but I lucked out this time. Great service, excellent job, and competitive price! Thanks, Corey read more
