If you’re thinking about installing replacement windows or a sliding patio door or a steel entry door but you aren’t sure because you’ve heard or read about the high pressure sales tactics, disappointing results or worthless warranties – we understand.

My name is Joe Kelemer, my brother Gabriel and I own our company. We started our company in 1999 with one purpose: make every customer a customer for life. Every window installation contractor will say they have experience. The Kelemer Brothers have successfully installed over 50,000 replacement windows since 1999.

We believe that this is the strongest evidence of our dedication to delivering quality window installations for our clients every time. In fact, we will provide you with a list of at least 100 recent clients and we strongly encourage you to call them and ask the tough questions.

If you are interested in energy efficient replacement windows backed by our Worry Free Window Warranty then our team has the experience you would expect from a window installation company that has installed over 50,000 windows. Call (410) 299-0038 for a free quote.

We provide each client with our detailed step-by-step process to install replacement windows. Our process is continually updated for changes in materials and installation methods and it sets a standard that very few of our competitors can meet. You will know specifically what we are going to do for the price quoted.

Companies that do this as a sideline simply can’t keep up. In addition, this isn’t something you can learn by reading an article in a magazine or online. Training from the manufacturer is the best way to keep up – and our crews spend time each month leaning about the latest innovations.
