You will be fortunate to find anyone in life as dedicated to their task as Jeff is to ensuring that the windows he cleans are, as other reviewers write, sparkling clean inside and out. He's knowledgeable (who knew that double-pane windows need buffing to get rid of mineral stains?), patient careful and a pleasure to work with. He's also fairly priced for the amount of care and effort he puts into the task. After he was finished I felt like shrink-wrapping my house so the windows would stay this clean forever. read more

Jeff at JK window cleaning was extremely knowledgeable and detailed. He came out the same day I called and provided a quote with options. We both agreed that my windows needed extra scrubbing. A few days later he came and cleaned all of my windows and sills and I am thrilled with the results. My windows now sparkle and are clear, clean, and beautiful. I'm so glad I called Jeff. He worked very hard and was methodical in his system. Thank you so much!! See you in the spring! read more

OUTSTANDING results. Jeff takes great pride in his work. We've had out windows cleaned several times and they have never come out better. Jeff is patient and thorough...we have 92 windows...and he took great care with each. We have already recommended him to our neighbors and friends. Great job, Jeff. Thanks. read more

I would make the same comments as previous reviews of JK Window Cleaning and Jeff; he is reliable, communicates well, is knowledgable about cleaning windows and other aspects of the home such as patios, gutters, etc. He clearly takes pride in his work and does not rush through the job. I agree that he is likely more expensive than some other companies, but I felt there was value in money well spent. It's been a couple of weeks and many rainy days since Jeff was here, and my windows still look great read more

Jeff did an amazing job for the 2nd time cleaning my windows! He's very reliable and has great communication.y windows are sparkling! He educated me and my husband on the process. He takes pride in his work and it shows. Jeff offers different levels of service and for my new home, I opted for the best and was glad I did. I also found out he performs paver cleanup so I will hire him for that next. Jeff is a great contact for homeowners who value quality and efficient service ! read more

Jeff was great! He gave a fair quote and showed up exactly when he said he'd be at my house. He did as great job on the windows and went out of his way to make sure that everything was good before he left. I would highly recommend Jeff for cleaning your windows Cary Z. read more

We've been in our home in Lake Forest for a few years - and from the start, was evident the windows had been neglected. I discovered JK Window Cleaning on yelp - and Jeff was very responsive. He was at our house within a couple of days to provide a quote - and only a few days later back to get the job done. In November! I am so satisfied! Our windows look amazing! Like they're brand new! JK is sure to pay attention to the detail. Thank you! read more

We live in a contemporary house where large pane windows are a defining feature, so it's important we found a great window cleaner. Jeff is a true professional at this and we'll be using him again. He dealt with probably 3-4 years of buildup on our windows pretty seamlessly. First, we reached out late Monday/Early Tuesday to get quotes in hopes to get this done before a party that Saturday. Jeff was out Wednesday to quote, and was able to come the next day, Thursday. We definitely appreciated his promptness. He spent nearly the entire days on the inside/outside of our windows and did a meticulously excellent job. He uses a deionizer to help lift dirt from the window, bronze-cloth, and an assortment of other tools. The attention to detail was uncanny, as he re-washed many of the windows 2, 3, 4, even 5 times to ensure a job well done. Jeff was also very knowledgable about proper window cleaning and care and gave great advice as to how to maintain our windows moving forward for longer life. He helped identify hard water stains, pigmentation, and other imperfections and how we might deal with/prevent them in the future. Finally, going above and beyond, he came back a few days later to take care of our very old/fragile storm windows with some special tools to get them out while ensuring they did not break. This was supposed to be extra cost, but he did it free of charge since he missed it in the original quote. I highly recommend Jeff to anyone looking for regular window cleaning maintenance. He wasn't the cheapest quote we received, but the service, attention to detail, and information we got was well worth the slightly higher cost. You can be confident you'll get a job well-done, and complete, if you choose to hire Jeff. We'll be scheduling him again come Spring! read more

We have used JK Window cleaning once last year and just recently. Jeff, the owner, was referred to us by our neighbor who said he did an excellent job on her windows. Jeff not only did a superb job on our windows outside and inside, but also washed and dried all our window screens. In addition, we asked that he clean our blue stone on the patio. He did a great job. I was surprised at the knowledge he had about the blue stone and how to take care of it. We also had him remove the sun protection film on our four sliding glass doors. It had begun to peal and didn't look good. It also causes a breakdown eventually of the seals around the window. This was no easy job, but Jeff removed it and the results were great. We highly recommend JK Window Cleaning. read more

Jeff is the BEST when it comes to cleaning windows! We have been working with him for a couple years now and couldn't be happier with the level of service Jeff & JK Window Cleaning provides. Our home is a mid century house that is half windows so it's critical that our glass is clean. Every time Jeff comes out its like we have a brand new house because the glass is SPOTLESS and beautifully clean!! Jeff is extremely thorough and handles everything with care. He's a wealth of knowledge and has taught us a lot about our windows / house, things we would have never known to do to prevent larger issues down the road. Some of our windows are very old and Jeff knows exactly how to delicately work on them, making sure they are perfectly clean! This review is long overdue and I can't say enough positive things! If you live anywhere on the north shore of Chicago (Highland Park, Glencoe, Winnetka, Kenilworth, Deerfield, Northbrook, Lake Forest, Evanston) and want to work with someone who genuinely cares about your home you have to work with JK Window Cleaning!! Provides awesome service, detailed explanation of his work, care to ensure that everything is done right and the customer is happy. Thank you Jeff and JK Window Cleaning for all you do to make sure our home is in top condition and can't wait to continue working with you in the future (as well as referring you to all our friends)!!! read more

JK Window Cleaning - Backside of house, difficult to reach windows, all spotlessly clean and perfect!! - Window Washing Near Me - Highland Park, Illinois

Jeff did a truly amazing job, my husband and I have never seen a window cleaning company use so many special tools to clean windows. Usually it's a squeegee and mop, but Jeff used what looked like a water filtration system to remove all impurities in the water. The water is pure and deionized which bonds to dirt on the glass and removes it. He scrubs the glass with a water fed brush, then scrubs every inch of it with some kind of pad, then rinses the entire window again. The glass was left wet, but I was amazed that after it dried it was so pristine! Jeff also uses a great screen cleaning machine which looks like a car wash. He ran every screen through there and they came out awesome!! We also had him clean the siding and gutters with what he called "soft wash" and they too came out great. I was very pleased with Jeff's work, I have never seen anybody use so many special high tech tools on glass. I would highly recommend Jeff & will be using him again and again. read more

Jeff went above and beyond for us, as we needed our windows to look great before we put our house on the market. We had cleaners come out and they didn't do the best job on the interior windows, and Jeff was able to help us out in having them redone. Exterior came out amazing too, and it was much better than any other window cleaning service we used in the past. Will be using him for all of my future window cleaning needs. read more

Jeff did an excellent job on our house windows. We had just gone through a renovation and construction so the windows were extremely dirty inside and out, he spent many hours working on our house and the result was excellent! It made a huge difference and he did a great job. He's clearly passionate about his job and treats his clients very well. I like that he does the work himself, no crew, so you get dedicated service that is extremely high-quality. Definitely a go-to service if you are looking for window cleaning. read more

Jeff did an amazing job on the windows in our house! I've lived in this house for almost 30 years and have had the windows cleaned every 5 years or so. Many of the windows have storm windows, which Jeff took out and completely cleaned. It's as if the glass is sparkling! I can't believe what a difference his meticulous cleaning process made! They have never looked so good! He was extremely responsive in getting back to me and then coming by to give me an estimate first. And then he was very flexible in what date would be best for me for him to come and wash/scrub/buff the windows. I cannot say enough wonderful things about Jeff and the results of his incredible window washing process! read more

A great quality service. i love the product Jeff uses, it keeps the window clean for a whole month. great guy and he provides the best service, he works very neat.:) read more

Best window cleaning you could ask for. Jeff is truly passionate about his work, professional, prompt, and he delivers exceptional service and results. My windows sparkle and stay cleaner longer because of the methods he uses to clean them. I'm so impressed. The rain comes after he washes the windows, and simply 'beads' off, without leaving behind the usual water stains. He is my go-to every spring and fall for indoor and outdoor window cleaning. Jeff may charge a bit more than your typical window washing service, but he's well worth it...the windows are washed more effectively and with greater care. He is a perfectionist while remaining an efficient cleaner, and goes the extra mile every time to deliver excellent customer service (he's returning an extra morning next week to do some complimentary buffing on a window or two that need extra care!) Call this business...you won't be sorry! read more

First and foremost, Jeff and JK Window Cleaning are passionate about Glass and Keeping It Clean! The attention to detail and excellent service is their pride. We have had our windows cleaned in the past; however, Jeff's windows are truly a step above the competition. Historically we have to get our windows done two times a year; but, now we only need to get them done once a year. Jeff used high speed buffing machines to clean our windows and the results are really amazing! The dirt just slides off the glass and the glass is truly left spotless. He even cleaned my interior mirrors. glass dining room table and glass shower walls and doors. Truly full service! Jeff's services are below what you would expect to pay. Most of the window companies we have hired in the past used to be done in less than two hours and cost twice as much without attention to detail, Jeff spent literally the whole day and ALL my windows are looking fantastic. JK Window Cleaning brings personalized service to a usually mundane service. Their passion for clean windows is infectious!. read more

Work is good, and diligent, but scheduling is overly involved and rather difficult if you're a busy professional. Prices are above average, but his work reflects that I think. read more

Let me just say that you will not find anyone who will do a better job on your window. Jeff is super meticulous, super dilligent, perhaps obsessive dare I say? about doing the best job possible. You will not be disappointed. He's hard-working, honest and takes pride in his work. We have kids that regularly smudge the window (not to mention draw on them with those horrible "window markers"!!) so after Jeff cleaned them, the difference was shocking--it was like getting glasses to see our backyard for the first time! We look forward to a once-a-year visit from JK Cleaning --so worth it. read more

Jeff takes window cleaning to a whole other level. Very few people take this much time to do their best and have this much pride in what they do. Perfect 10 read more

As I started to call them on Monday, I hung up quickly as I thought I had misdialed. Before I could dial again they were calling me and asked how they could help. I explained my situation about needing my windows cleaned. He asked me to fill out the form on the website and we made an appointment for them to come out the next day. About 1/2 hour before the scheduled appointment I received a call they were running a bit late but would be there by a certain time. And they were! My windows and my screens were cleaned that day as they had the time and it was a perfect day for window washing! What a delightful unexpected surprise. They did a fantastic job and I have already recommended them to 2 of my neighbors. It is hard to find anyone to clean individual condo units in a four story building without being guaranteed business from multiple tenants as no company wants to waste their time with only one unit! I will gladly have JK Window Cleaning back to my house very time! Thank you Jeff! read more

Wow! That's all we can say! My husband and I interviewed 3 window cleaning companies and, hands down, chose JK Window Cleaning. They and their results are head-and-shoulders above any window cleaning company in every category. Jeff, the owner, used this special method that resulted in the absolute most sparkling, thoroughly clean windows. We think the differentiating factor when we compare his work to others in the past is that his results last. The windows stay cleaner longer because of the special soap or whatever he does or uses. He is extremely professional, super nice, meticulous and customer-focused. The pricing was very competitive, yet the workmanship, superior. We will not go anywhere else. We take pride in our home and we want our windows to match the quality of our home. JK Window Cleaning has completed most of the houses on our block now. EXTRAORDINARY RESULTS!!! Thank you, JK Window Cleaning!!! Always a pleasure!! read more
