I work hard for my money but obviously don't have time to clean windows! Jeff with Sinclair Window Cleaning is worth every penny and very reasonable. Very easy to get a hold of to schedule a cleaning and professional service. read more

Jeff gave my windows a new life for a great price! I'm so pleased!! Definitely going to use again.

This review is overdue! Sorry, because Jeff is awesome .. I was having a very special event at my house and wanted my windows to sparkle more than I could make them. I yelped and found Sinclair Window Cleaning. Everything written is completely true and then some! He called back immediately.. Worked it out for my schedule.. Called to ask about changing the time slightly but well in advance!, ...and showed up exactly when he said he would! The end result left my windows and screens looking brand new! And a bonus was that my nozzle had been stuck on my hose for weeks, Jeff took the time to get a tool and remove it for me! A very nice honest guy who does great work! I will never bother to call another service and plan to use Sinclair on a regular basis! read more

First time having our windows and screens professionally cleaned and it was well worth it. Jeff cleaned all of our windows, screens, and tracks both inside and out. He showed up with his fully-equipped truck (ladders, hoses, vacuums, water pressure tanks, you name it) and did a fantastic job in three hours. He was professional, personable, and knowledgeable. If you are in need of this kind of service (and you probably are if you live in Rancho) look no further than Sinclair Window Cleaning. Highly recommended! read more

Honest and thorough at highly competitive rates! Tough to find these days, especially given the current economic climate. Sinclair Window & Solar Panel cleaning is the gold standard in the business and Jeff's business practices are the epitome of integrity! read more

Called Jeff as I needed help on short notice for a big party next weekend. It took a little text-tag to work out a schedule, but Jeff's communication was prompt and accommodating. Jeff arrived a few minutes before our appointment time today, and got right to work after a quick review of my expectations. He did the outside of the house first, including the (admittedly) filthy screens, then took care of the inside right away. He worked efficiently and well, was careful with things in windowsills or where he had to reach around things in the home, and was done in a few hours. Anyone can clean a window. It takes a pro to do it well and cheerfully! Jeff of Sinclair Windows is that pro. Many thanks for rescuing me from several days of drudgery, Jeff! read more

My husband and I are both very satisfied with Sinclair Window Cleaning. We highly recommend Jeff to you. Not only were we completely satisfied with his work, but his professionalism and expertise helped us know and understand the process of window cleaning. He recommended a few tips for us and we learned a few things about how to and not to clean windows. We are definitely cleaning our windows more often with him and we highly recommend that you given him a call too! read more

Jeff just did our windows and he did an AMAZING job. They look beautiful! He also repaired the screens for a door and two windows and did a great job. Plus he's super nice and professional. A++++++ read more

We have 40 or Windows that were really hammered from having the house painted. Jeff spent the better part of 6 hours cleaning them. Did a great job. read more

Nice guy, did a great job. Even on difficult areas and I thought the price was very reasonable for the work done. Go ahead and give them a call. read more

I will definitely use Sinclair Window cleaning again. Jeff is prompt, professional and knowledgeable. He replaced the screens in our patio room several months ago. Today he cleaned all our windows. They are sparkling. Even the screens and tracks look great. read more

Another 5 star review for Jeff!! He is so easy to work with on scheduling, he is a very nice, friendly (but not overly friendly if you know what I mean) guy that enjoys his work and does a terrific job! You might find someone to do it a little cheaper but you won't find anyone better! Our windows are now invisible and the tracks and screens are clean. read more

First time I have ever written a review on YELP but am just so pleased with Jeff Sinclair, I feel I must! A really nice guy - very personable and did a great job on my windows and skylight! He was efficient and had lots of good tips too! I highly recommend him! Kymm read more

I was so terribly embarrassed about my windows. They were in need of some SERIOUS help! Enter Jeff and WOW! My windows are beautiful! He cleaned them inside AND outside, cleaned and oiled my tracks and repaired screens. Having your windows cleaned is such a luxury, and thanks to Jeff it's an affordable luxury! Thank you Jeff. I am a VERY happy and satisfied customer. read more

I just had the pleasure working with Jeff. It was quite the experience. Not only did he do a great job, and quick too, he was super nice and willing to work with my budget. I have had him out twice now and don't have any plans on finding someone else. He is a great guy, does a great job and has a great price. I have already recommended him to 2 other people I know and they both had the same great experience i have had! Thank you Sinclair Windows! read more

Jeff cleaned all the windows in our house and did an excellent job. He was much more thorough than a former company we had used. He was flexible with our schedule and showed up on time and his price was very good. We will most definitely be using Jeff in the future and would highly recommend him to anyone considering having their windows cleaned. Thanks for all your hard work Jeff, we are enjoying our sparkling clean windows! read more

After doing a lot of searching for someone to come into our home to clean our windows, we ran across Sinclair. We were so impressed by the ratings that we had to give him a try. Jeff came out today and I can honestly say the 5 star ratings are 100% true. We are so impressed!!! Thank you Jeff for making our house sparkle! We will without a doubt be returning customers AND we will be singing your praises to everyone we know. read more

Jeff squeezed me in at the last minute because I told him I was hosting a party. He did a great job on my windows, screens and tracks! I can't believe how smoothly my screens roll and how my windows sparkle. He is professional, personable and I felt comfortable having him in my home. He even wore shoe covers! I will definitely use him again. read more

Excellent job! I highly recommend this company. I will be calling Jeff back for additional work. Priced to beat or match others and quality work. read more

I highly recommend Jeff for window cleaning service. I understand he does commercial and residential window cleaning at a reasonable price. He's professional, very friendly, hard working and does excellent work. He's cleaned my windows a few times now and has done great work. He even replaced one of my torn window screen the last time he was here. Make sure we give him plenty of notice, he's a busy guy and a couple weeks notice is probably the best way to get an appointment. Well worth the wait! Thanks Jeff! read more

Jeff does a fantastic job. He has followed us house to house and will continue to do so for years to come. I even referred him to a commercial building for my landlord and he was ecstatic! Great guy, happy to give him a 5 star review! read more

Jeff did our windows yesterday and we were amazed and very pleased. He exceeded our expectations. They look as bright and shiny as they day they were installed (including the frames and tracks). We had used another service for years but it did not begin to compare to the wonderful job he did. We had water spots on several windows and he was able to completely remove them, restoring my view of our bird feeders. He is extremely professional and seemed to take great pride in his work. He is extremely neat and conscientious, protected our carpet and flooring etc. Needless, to say we will be having him do our windows from now on! read more

As we prepare to sell our home we hired Jeff Sinclair (who is personable and attentive) to power wash and clean windows. He did a great job, even got stains that we didn't expect to go away off patio and driveway. We are now shiny and clean! read more

RUDE! don't know about washing windows or solar panels, but phone etiquette severely lacking. will not use this 'service' ever.
