I called Diamond after reading the many positive Yelp reviews. They were able to accommodate my schedule. They guys did an outstanding job on my 20+ windows. They cleaned the screens and tracks as well. I highly recommend Diamond and will definitely use them again. read more

Can't find words to say how happy and grateful I'm for Diamond's service. It is truly a Diamond's service. ! I live in apartment complex and haven't cleaned my windows for years ( shame on me :( ). When the outside world became blurry I decided to call for help because myself didn't know where to begin ( it was so dirty ! ). I contacted Diamond's and decided to go with them purely because I had no time to contact other companies and price was very reasonable. Stephanie was super nice when talking to her, explained me prices and how they work, I scheduled the visit, guys came 10min before time and did an awesome job. I honestly didn't expect that my windows and my balcony which I asked to clean as well could be this clean. I'm BLOWN AWAY by the quality of their work. Very professional service, super nice people, and excellent quality of work. I'm contacting them next year for sure !!! to keep my windows shiny as they are. Thank YOU Diamond's !!!! will be coming back to YOU. read more

It is so refreshing to get excellent service and very conscientious workers. i will definitely use them each year. read more

Stephanie came out on time, actually early, to estimate the job, which was a very reasonable price. The three person crew did a fantastic job cleaning the windows in my condo inside and out. Three of the windows are located in a two-story stairwell, and they were able to get up there on a ladder easily. I wish I had used their services sooner. read more

Diamonds window cleaning did an amazing job in my house. Quality work, great price. This guys are fantastic.

Called left message. No call back. Sent message via yelp as it shows two hour response time. No response. Business must be great for no response back. Glad all that reached them have excellent feedback and were able to receive a response from the owner. read more

These guys did an excellent job cleaning my gutters. I've had this done in the past by a different company, but Diamond was so much better. First, it was easy to get a quote, and schedule and appointment. Second, they did a great job, and unlike the other company, did an impeccable job of cleaning the gutters and any of the dirt/leaves that comes out of them. There was a huge storm after they cleaned the gutters and I had no "waterfalls" anywhere off my roof! read more

Thank you so much Stephanie for working around the rainy weather and getting me on the books within the same few days of my original appointment! The guys were wonderful; polite, efficient and careful to always use booties over shoes while in house. Windows look great and I'll be calling again for sure!! read more

Stephanie is easy to work with. The crew that came out to do the work are professional and respectful. They charged a reasonable fee to repair the screens. read more

Diamond's Window Cleaning did a great job from start to finish! Excellent and fast communication, Stephanie is awesome! I even received a call from her letting us know that the crew was running a few minutes behind. The crew, Josh, Reuben and Marlon, did an excellent job cleaning our windows, screens and tracks. There was some paint on our windows from a recent paint job and Josh was able to remove it. The entire team was fast, efficient, professional and friendly. I definitely recommend them! read more

The company I work for has been very impressed and very happy working with Diamond's Window Cleaning. Stephanie, the estimator from Diamond's is a very professional, clear and efficient communicator. She arrived promptly to carefully observe the details of the job and gave us an estimate within 24 hours as promised. Scheduling our first appointment, for three men to come out to clean a very long glass wall enclosure, was easy and efficient. I was thrilled to see that they showed up when they said they would and took care of the job in a conscientious way. We schedule Diamond's to come out every two weeks and they always show up and do a wonderful job. We love how much pride they take in their work. Diamond's is a fantastic company with professional and friendly employees. read more

I needed the exterior windows and screens cleaned. I called the company and got a quote on the phone. On th day of the appointment, I got a phone call from the company saying they were going to be 15 minutes late. I appreciated this courtesy call. The two men that came were polite and did a very nice job of cleaning the dirty windows and screens. They will also clean inside windows and dirty tracks so next time I want to do that. read more

Just had my windows cleaned by Diamond and I'm very happy with the result. They were on time, quick and careful not to make a mess.

They also cleaned and checked our gutters which puts my mind at ease for the winter rains to come. I highly recommend them! read more

Just had my windows cleaned by Diamond and am very happy with the great job. The guys were very nice and polite and wore shoe covers which I appreciate. They cleaned the windows, screens (which were coated in dust) and tracks. Now sparkling and crystal clear! I have a security screen door and they cleaned that as well - it hasn't looked this good since I first bought it! Stephanie was very responsive, getting back to me quickly here on yelp and on the phone. Great customer service! Will use them again. read more

Great service. I asked for a quote online and Stephanie got back to me very quickly. Once I agreed to use this company, a team was able to come quickly (within a few days), when the other company I contacted could not come before Christmas. The two gentlemen who came to do my windows and skylights were extremely polite, professional, and they did a great job. My house does look like a diamond now ;) read more

The entire team from quote to work done were fast, responsive, nice, informative; generally well worth the price. The cleaning team they sent over was fantastic about communicating with me on what they were doing, what work was done, and even the stuff they couldn't take care of and why and they even gave me tips on how to get things fixed. We will definitively be using them again! read more

Set up a window cleaning through Yelp messaging -- Stephanie responded immediately, and an appointment was made within a week, working around my schedule. I needed two bedroom windows cleaned on the outside as it's the third-story of a condo complex with no outdoor access to the windows. They also cleaned my downstairs neighbor's windows. Perfectly clean, and the cleaners were professional and went the extra mile to take care of us. Four sparkling windows and cleaned window screens. The cleaners made sure I looked everything over to make sure they got everything. Very convenient and inexpensive service with amazing results. My neighbor and I will be using them twice a year now. read more

I highly recommend Diamond's Window Cleaning, they were on-time, professional but also friendly. They did a fast thorough job cleaning windows, skylights, and the very dirty window sills. Joshua was the supervisor for the job and he kept everyone moving. read more

These people are first class window cleaners from beginning to end. We got a quote back in minutes even though I contacted them late in the day. They came on time on our preferred day, wore booties in the house, did an incredibly thorough job and conducted themselves as friendly professionals. Our neighbor already signed up to use them - they will be our window cleaners as long as they stay in business, which I would guess would be a long time. read more

We went with Diamond's for gutter cleaning of our two story house. Stephanie handled the initial communications and quickly responded to my repeated emails. Josue and his assistant arrived on time and set about cleaning the blockages around the roof. We also paid for cleaning the outside of the gutters which had some dirt buildup. When they were done, everything looked clean and Stephanie provided a full set of pictures showing the various areas of cleaning. Pricing was reasonable. read more

These guys showed up right on time, very polite, professional. My windows and doors, screens and tracks were never this clean for decades! Love the result! Definitely have them back. read more
