Kelemer Brothers

Gabe provided great customer service & oversight of the project from start to finish. The crew was experienced, efficient & handled everything with care. We are very satisfied with the results. If you are looking for new windows I highly recommend you give Kelemer Brothers Windows & Doors a call.

Kelemer Brothers were absolutely amazing. From the estimate to the installation, everything was perfect. Their installers were nice, professional and meticulous with installation, old window removal and clean up. Gabrielle was great and always stayed in contact throughout the entire process. And they gave us the best price ever. No one could come close. I highly recommend them for any window needs.

Very professional and polite crew. Work was professional and cleaned up well. 15 windows and a slider done by 2pm.

My wife and I couldn't be happier with Kelemer Brothers Windows! Joe Kelemer, the owner, came out to our house personally, reviewed the job and took the time to explain all our window options, including energy savings, security features, and aesthetics. He listened to our needs and provided a competitive quote and delivery date quickly. After a quick review of the options, my wife and I decided to go with Joe and his team. The installation process was smooth and efficient – the team was professional, clean, punctual and finished the job within a few hours. Joe even came by personally that same evening to inspect the work and ensure our satisfaction. Overall, it was an exceptional experience. We highly recommend Joe Kelemer and Kelemer Brothers Windows!

I got 24 windows replaced by the Kelemer Brothers. It was done all in one day by two crews. Communication with Joe was timely throughout the entire process and he was helpful. Things appear to be good regarding the windows, but it has only been one day. I ended up choosing Kelemer Brothers due to the stellar reviews on Google in the hopes that everything would be seamless. Unfortunately, two of the blinds that they took down and reinstalled ended up getting stuck, and ripped once I got them loose. They were working perfectly beforehand. Three other blinds that are exactly the same had no issues. One blind, once loose, had a part fall off completely and ended up breaking into 3 pieces, so that blind is now trash unfortunately. I have 24 great windows and sadly two ripped/broken blinds.

We recently had the pleasure of working with Kelemer Windows for the replacement of five windows and a patio door, and our experience was nothing short of exceptional. From the moment we placed our order, the process was smooth and efficient, lasting eight weeks between the order and installation dates. What truly set Kelemer Windows apart was the personal touch they brought to the table. On installation day, one of the owners (Joe) showed up with thoughtful gifts for us, a gesture that speaks volumes about their commitment to customer satisfaction. It's these small yet significant details that make supporting small businesses like Kelemer Windows so rewarding. In a world dominated by large corporations, it's refreshing to encounter a company that values its customers on such a personal level. Moreover, the quality of their workmanship was impeccable, and the cost was very reasonable, especially considering the level of service we received. We were so impressed with their professionalism and attention to detail that we've already decided to return to Kelemer Windows for the replacement of our remaining windows. For anyone in the Washington, DC region in need of new windows, I wholeheartedly recommend giving Kelemer Brothers a try. Their great rates, excellent service, and personal approach truly set them apart from the competition. Thank you, Kelemer Windows, for exceeding our expectations and transforming our home with your exceptional craftsmanship.

We had been putting off getting new windows for years, because of the expense. Finally decided…or the water coming in the front window decided for us, that it was time. I reached out to a few companies, big ones and small ones and scheduled estimates. Kelemer Brothers was the 3rd company to come by. As soon as I met Gabriel I knew this would be the company. I didn’t feel pressured, he did didn’t tell me in advance to have my husband available or a lot 90 minutes for a presentation. He came in, talked to me about what we were looking for and any problems that we were experiencing. Inspected and measured each window. Then shared with me his product and what his company could offer. Went out to his car and prepared a fair and AFFORDABLE quote. A quote that wasn’t going to change if I waited until the next day. That is how it should be! The day of install was also a great experience. I’d highly recommend Kelemer Brothers for your next purchase of windows or doors!

Kelemer Brothers replaced all my windows back in 2012, and I was very pleased with the windows and installation. This week I was cleaning windows and when I went to tilt one of them back up to close it, something snapped and the window wouldn't go back in properly. I contacted Joe and he responded within minutes. He came out later the same evening and within 10 minutes had replaced the broken piece and had everything back to normal. I feel like that's a very impressive level of service, especially since the windows were installed 11 years ago! They're just good, honest people who are a pleasure to work with.

It's been almost a year since I had my new windows installed. I waited to be able to give a better review. The whole experience was great and so are the windows. They are not high pressure sales and everything was honest and accurate. I had another (high pressure) company present the same windows and they did a very long presentation with a lot of information which Kelemer did not do. I could have used less presentation from the one company and more presentation from the other but for me, it all worked out. Just know, you will get a great product without a big presentation of "why you need these windows" and why you have to buy now. All 17 windows were installed in my townhouse in one day with no issues. This past year, my house has been amazingly consistent on each floor. No more hot/cold spots as I wander around. These guys offer a great product, great service, great communication, and are very responsive. I was wondering how they could get so many 5 star reviews and now I know!

The big task finding reputable window company was made easy by contacting the Kelemer brothers, They are outstanding installers replace 21 windows efficiently in one day. while they are a couple of glitches they were resolve quickly to our satisfaction by great customer service , They were a highly reputable dependable company to do business with.

Work performed was excellent. Highly recommended.

Kelemer Brothers replaced all my windows in 2015. Everything about this company was stellar from start to finish. Recently, one of the windows would not stay open. I reached out to Joe who ordered the necessary part & came out himself on a Sunday to make the repair. At no charge. I have never dealt with another company as responsive as Kelemer. I cannot say enough good things about them. Highly recommend.

After receiving a few “teaser” prices from other contractors, Kelemer Brothers was refreshing. The salesman was prompt, polite, and knowledgeable. The windows were very well constructed and delivered well before expected. The molding did not have vinyl “flash” present. All the seams were neat and tight. The installation crew was clean, neat, and efficient. The windows were set and foamed in place. The craftsman completed the break metal to seal the windows. The joints were tight. The breaks were clean. The trim was exceptional. Would I use them again? Without a moment’s hesitation. Great Job Joe!

Working with Gabe was a pleasurable experience. He recommended exactly what we needed for our kitchen door replacement. He promptly answered all of our questions. He came after the door was installed and went over and explained all of the features of the door. Our installer Ziggy was wonderful. He was efficient, knowledgeable, and a perfectionist. He even went above and beyond in helping us with some issues with our front storm door. We can’t say enough about how easy and wonderful it was working with Kelemer Brothers. We highly recommend them!

HAD NEW WINDOWS INSTALLED THROUHOUT MY HOUSE AND IT WAS THE BEST EXPERIENCE I HAVE EVER HAD WITH ANY BUSINESS. THEY WERE HASSEL FREE, ARRIVED WHEN EXPECTED TO, CLEAN, EFFICIENT, AND VERY COURTEOUS. THE OWNER CAME AFTER THE JOB WAS DONE TO BE SURE EVERYTHING WAS TO MY SATISFACTION, HE EVEN BROUGHT ME FLOWERS! WILL BE RECOMMENING THEM TO ALL MY FRIENDS AND NEIGHBORS!

The installers arrived on time. They took the time to cover the work area. They worked well as a time. Mr. Kelemer checked on the progress of the crew several times during the installation of the windows and the sliding door. He even brought us a bouquet of flowers, thanking us for being a customer. After the installation was complete, Mr. Kelemer showed us how to open the the windows and door. Everything went as planned, with no surprises. When we received the estimate for the job, there were no long presentations to listen to. Mr. Kelemer just took the measurements and suggested what windows would work best for us.

Had a great experience! Kelemer Brothers were professional, honest, informative, and did excellent work. I had most most of the windows in my home replaced, and I couldn't be happier.

Reviewing, selecting, purchasing, installation went smoothly. Kelemer Brothers worked with us and kept us informed throughout especially as supply chain issues were going on at the time. Worked with Gabe Kelemer. When we had some minor adjustments he came out & installer came out & resolved satisfactory.

Joe and his team are very professional, they are very kind and respectful. Joe spent a lot of time explaining details about our project. The installation team did a great job.

I found Kelemer Brothers on a random google search and decided to give them a call. When Gabriel came to provide me an estimate, he asked how I heard of them. I told him that I found them on a google search, saw all the 5 star reviews, and thought, no one could be that good and I wanted to see if he was full of… “stuff”… Now, I’m writing to say, he’s NOT full of… “stuff”… Kelemer Brothers started off a leg behind in my search. The day before, I had signed a contract with another company. I told them the price I wanted, they met it, so I signed (I had 5 days to cancel). I had Gabriel come out anyway because I wanted to see what he’d say. Gabriel was outstanding to deal with. He was the only one who walked into my house, looked at my windows and could point out which ones previously had glass replaced and which didn’t. There was no sales pitch, no hard sale, no gimmicks. He walked around, measured the windows, tapped some numbers on his phone and showed me a price. Back to that offer I already signed… Long story short, upon further review, they pulled a bait and switch and put different windows on the contract. Four days later, I had come to an agreement with Gabriel and canceled my previous contract. Alright Gabriel, I’m giving you a chance, don’t let me down! Fan-tastic! Gabriel was a pleasure to deal with start to finish. Very classy guy. His crew was very professional. They worked hard and consistent. They didn’t rush. They were clean and took care of my house while they were in it. They vacuumed and cleaned when they were done, they left no mess; when they left, I barely knew they were there. Gabriel brought flowers for my wife (she already liked him better than the other companies…) Gabriel was around to answer questions during the install. Any issues that I had with the install (I had minor nit picky things because I’m OCD) they addressed immediately and without issue. There were 2 screens that were ripped, Gabriel fixed them right there on the spot. Every window was installed well, was working, and I’m honestly very happy. It’s only been 3 days since the install so I can’t speak to years gone by, but very happy so far. Lastly, all the other guys came out with their sales pitches and how the materials they use are soo much better than everyone else… Kelemer Brothers used all the same material. All high-quality foam/caulk/trim/etc. Thank you Gabriel, thank you Vince, thank you to the rest of the crew!

Kelemer Brothers is an exceptional business. Their professionalism, customer service, integrity, and workmanship are beyond compare. All aspects of the extensive 24- window replacement could not have been a better experience. All busineses should operate like Kelemer Brothers!

I thought I needed new windows as they kept dropping down but the owner Joe Kelemer looked at them and advised me that I do not need new windows and spent time showing how to close them the right way. A very honest man and will hire him in a second. Honest people are hard to come by and Mr Joe Kelemer is an epitome of one.

Great customer service and excellent workmanship. Windows look beautiful. Highly recommend.

Kelemer Brothers did an excellent job replacing my windows. They were professional, punctual, and responsive to questions. Joe, the owner, was very knowledgeable about the window product and installation. The crew cleaned up as they worked and after all work was completed.

From the initial quote to the final install, Kelemer Brothers were an absolute pleasure to work with. They were very responsive to any questions and took the time to explain their product and the installation process. The project was finished on time and there were no problems at any point. The finished product looks even better than I anticipated and their price was the best of multiple estimates. I would hire them again without hesitation.
