I just bought a house in Oakley and the house came with a Solar Panel. I heard stories about Solar panels being nested by birds and I decided to install wire mesh. After inquiring about quotes from Yelp, I decided to get the services of R12 Window Cleaning. Tim, the owner, contacted me right away and gave me a reasonable price for his service. Tim arrived on time and explained the process of his service. He was very knowledgeable and gave me all the details regarding pegion abatement. The work was very professional. I might call him again to clean my solar panels once construction in our area is cleared. If you have work regarding solar panels, I highly recommend Tim and R12 read more

R12 is such an amazing business! They have cleaned our solar panels and windows for a few years already! I recently received a notice from my insurance that they were cancelling my insurance due to mildew and debris on my roof! I contacted the owner, Tim, and told him of this! He came and explained the mildew and had it cleaned! They did an amazing job, sent me photos, and a receipt! He told me to submit all that to my insurance company who never told me what to do! Tim also advised me to ask the insurance company for the inspection report as well as the photos! I did and I found out that 7 months earlier they had a drone fly over my house! The insurance company accepted my photos and receipt for payment to R12 as a remedy to the problem and they rescinded their notice! If it wasn't for Tim I would have gone and found another insurance company which is currently impossible in CA! Thank you R12!! read more

We had a very positive experience with R12 Window Cleaning. We had a very challenging situation due to how our solar panels and patio cover were installed and several other companies told me they were to do the job. Tim and John problem solved several solutions before successfully installing new bird proofing mesh around our solar panels. They also cleaned our gutters and solar panels. Tim was highly knowledgeable, very professional, and had excellent communication. His pricing was also much more reasonable than another estimate that we got. I would highly recommend R12! read more

Tim was very easy to work with, scheduling was flexible, and his price was reasonable. I could not have asked for better quality work and professionalism.

Just did a amazing job on a last minute call.

R12 Window Cleaning - Window Washing Near Me - Brentwood, California

Spoke with Tim for a gutter cleaning appointment and managed to secure a reservation 3 weeks out. Pricing was towards the higher side but they were willing to provide proof of insurance which was extremely important if someone is going to be working on your roof from a liability perspective... Shane showed up on the day of the appointment towards the later part of the window and managed to clean out the gutters by walking on the roof, using water and a leaf blower. The entire exercise was complete in an hour. Pricing was marginally negotiable and payment by check to the business was preferred. ...all I had to do was reconnect my water hose in my front yard when Shane left... read more

Tim is exceptionally responsive and easy to get a hold of. He offered to do an over the phone estimate or send someone over for a more accurate estimate. The quote was reasonable and straightforward. Shane came out to clean the windows and he was honest and forthcoming about the state of the windows. He let us know which ones were beginning to have moisture accumulate and which ones we need to be careful of if we clean on our own. He respectfully wore booties in our home. Please note the coupon available through yelp applies to gutter cleanings only at this time. Thank you Tim and Shane! read more

Tim was very friendly and educated me on my roof cleaning needs. He came over to do our gutter cleaning and was able to accommodate our scheduling. The gutters are now clean and he assured us the work has a 6 month guarantee in case we run into issues. Thanks Tim! read more

R12 is wonderful to work with. Owner, Tim, takes pride in his work and is personable, reliable and responsive. He takes care of our gutters, solar washing and recently did our solar abatement. They provide before and after pictures of everything. We will continue to work with R12. read more

Tim was great! He came to give me a free estimate for bird abatement and solar panel cleaning. He took pictures to show me how badly my roof looked. He made suggestions to me. And when we hired him, he took pictures to show the finished product. He was very thorough. He even went above and beyond for me with the cleaning the perimeter around the house. After all that, he checked up on us a couple days later to see if we were satisfied. I will definitely be using him again for solar panel cleaning. read more

Our gutters were long overdue for a cleaning, and with all the rain we've been getting lately we knew we had to get them taken care of ASAP. I reached out to R12 on Yelp and got a response right away. Tim was able to look at our house on google and give us an accurate quote which included a Yelp discount! Tim showed up promptly at the scheduled time and was very friendly and knowledgeable. He finished the job in less time than estimated and left a tidy pile of all the stuff he pulled out of the gutter by the curb. He cleaned and rinsed out the gutters and made sure there were no clogs and offered a 6 month guarantee on the work. I'll be calling Tim again next year when we are due for another cleaning! read more

Tim did a great job. Cleaned our windows inside and out, screens, solar panels, and skylights. Our house looks much brighter and cleaner, and we are now ready for winter rains. (Rain + dirty windows and screens = ugly mud-streaked windows) Enjoying our sparkling clean outlook! read more

Tim was great! He showed up on time and did a very thorough job on our windows! His prices were more than fair, and beat out all the other companies I called by far. Our windows look the best I have ever seen them, and our neighboring business owner has already come over to ask for our window cleaner's contact info. Overall, he was honest, got the job done well, and is now our go to guy for window cleaning. Bottom Line: I highly recommend using R12 Window Cleaning! read more

Awesome gutter cleaning service! I called around and most places did not answer their phones. The couple I did get a hold of were widly more expensive. Pros: I called on a Tuesday, they came out the very next day. They offer a Yelp deal. Just mention it when calling. Since I could not be home at the time of the cleaning, they sent me before and after photos. I asked if everything looked in good condition. They were honest and did not try to upsell anything. I highly recommend them! read more

I got a great quote for Gutter cleaning and Window washing from Tim over the phone. He explained to me the details of the work that would be performed, and set up an appointment for the week after. On the day of the appointment, Shane arrived right on time, and started with gutter cleaning. He climbed on the roof (we have a 2 level home) and cleaned all the gutters. He told me about a gutter that was leaking, and how to fix it once it was dry. After cleaning the gutters, Shane started cleaning the windows and the patio door from inside. He worked quickly and efficiently, but made sure that the quality of work was top notch. He explained to me how he cleans the windows, what tools he uses and even gave me some great tips on cleaning the windows myself! After cleaning the windows from inside, he took all the screens outside, washed them, and then used a special tool to clean and wash the windows from outside. He finished the work by installing the screens and doing a walk through with me for the final inspection. This is where the things take an interesting turn. A few minutes after Shane left, I noticed that a few windows had some water and dirt left in the tracks, which I missed during the inspection.I called him immediately and he offered to come back and fix all issues in a few days. I also emailed Tim about it, and was surprised when I got a call from Tim in a few minutes. Tim offered to come by my home the very next day to take care of all issues and ensure that I was "110% pleased" with their work. He arrived on time the next day, apologized for the inconvenience caused, and immediately went about inspecting all the windows and cleaning wherever needed. He also cleaned all the mirrors in my home! I am enjoying my newly cleaned windows as I write this review. I am very pleased with their work, and their awesome customer service and will be definitely hiring them again for getting my windows and gutters cleaned! Highly recommended! read more

My windows are spotless and my experience with both Tim and Shane was super! Tim got right back to me with a quote, scheduled a date and got me on their calendar quickly during a busy time. I was notified the day prior with the name of the person to expect the day of the appointment. Shane arrived promptly on time. Did an excellent job - all on his own in a short time! Super efficient and quality work. Very pleasant team to work with, beautiful shining windows, doors as well as sky lights for a fair price. Shane pointed out to me the overgrowing wisteria on the roof as well as an issue with one of my glass doors. Shane did a better job than a team of 8 that cleaned my windows the year prior. I am glad to have found R 12 team and will definitely call in them again. read more

Annual cleaning of all windows and screens.. job is always remarkable and crew is friendly and professional. I will continue to use them yearly.. read more

At some point in the future, I will be calling on Tim to have my windows cleaned but in the meantime, I did call on his wife, Tammy & her housecleaning service. We have had house-cleaners for the past few years, every two weeks. Some were good, some were great & the last one we had was just so-so. Tammy & her daughter arrived on time and did an amazing job. They cleaned everything and got down to the nitty gritty, which the other cleaner had not done. They spent more time than predicted but the work they did was excellent. I now have them scheduled to come every two weeks to keep up the awesome job they did. Thanks Tim for the referral to Tammy!!! read more

Knocked on the door one morning a few days after I'd had surgery and wasn't answering the door quickly, much less for unexpected visitors. I never said to come over yet this guy ignored the fact that no one answered and decided to let himself into my backyard and start looking around! I sleep with my curtains open and was afraid this trespasser, not knowing who it was or why they were there, was going to see me in bed with medical equipment and everything. UNACCEPTABLE! read more

Used R12 a second year. Quick, efficient, super helpful. Thanks Tim!

This company did a really good job on my many 3 pained windows and French doors, screens and window sills. AND they were more reasonably priced than their competitors. They're name refers to Romans 12:12, by the way! Highly recommend these guys! read more

Tim came out and did an estimate for gutter cleaning. The next day Shane came and cleaned them. He did a very excellent job, and I'm very happy with the results. read more

Shane from R12 came out for a gutter cleaning. After doing an inspection, he advised I did not need the full gutter service since only a few pieces of debris were blocking water to the downspouts. He also fixed a loose downspout for me. Overall, I really appreciated the quick response in scheduling an appointment via text with Tim. Shane was great and was honest in letting me know that the gutters only required minimal cleaning which meant the service cost me less than I was expecting to pay. I highly recommend R12. My next call to them will be for windows after the rainy season. read more

If you are looking to get your windows cleaned with good pricing, this is the company to go with. I looked around and called around and when I contacted this company, Tim came to my home within an hour to give me an estimate. I asked him to look at the gutters and after looking at them, he said they are good no need to spend money on them. What honesty. On Friday he came to our home, the job was to perfection. Windows were very clean with no drip residue anywhere and my floors and walls were clean too. I have had bad experiences with lines on my walls and floors with spots, but not with this company. Give them a try you will not be disappointed. read more

Had R12 come out for a move out cleaning and window washing. WIN: 1. Window cleaning was outstanding. I would recommend them for this. 2. Most of the house cleaning was done very well. Baseboards cleaned, cobwebs disappeared, carpets vacuumed, etc. They did spend 5 hours cleaning an empty 3 bedroom, 2 bathroom, living room, kitchen, family room, 1430 sq ft house. FAIL: 1. Bathroom cabinets & shelves were not cleaned 2. Entry way light was not dusted 3. Blinds were not cleaned as requested (I spent 2 hours cleaning them myself after R12 left). Some blinds were dusted. 4. Oven was wiped out, but not cleaned. Evidently they will not use chemicals to fully clean ovens. They should state that on their website. 5. Steam cleaning vinyl flooring. It was going to take 2 hours to steam clean my kitchen floor. Ka-ching! Thanks, but mopping worked just as well on the brand new floor instead, and much less time consuming. This should be an additional stand alone service that can be added by the customer. read more

I made an appointment, Shane came out on schedule, did my windows inside and out - screens too, power washed my decking and the front landing to the entrance, fabulous job. My windows are so clean, it looks like I have no glass! I will do this every year going forward!! Great work, they answered their phones, scheduling was easy, service was good. Really happy with them! read more

Upon searching Yelp for a contractor to clean out our gutters, I found R12 and a few other companies. R12 was very easy to get a hold of and gave me a rough quote over the phone. I was able to simply make an appointment and they came and did a awesome job. They cleaned out the gutters, blew all the pine needles off of the roof as well as cleaned up the loose debris on the front lawn and driveway. Reason it's only 4 stars is that it ended up being on the higher end of the quote. The previous year I used a company on craigslist that didn't do quite the same quality, but roughly half the price. read more
