"My view of the back yard was greatly improved by the larger window. At first they weren't sure they could give me a sill, ended up they did. Age of my house (1945) and more than one photo (one from inside) might of have been helpful to the installers. Mortar/cement was made to last so they had some trouble getting the bricks out. Came back the next day to finish trim. Stanek did send someone out to adjust my back door. They fixed the tight latch on the window at the same time. A minor adjustment. I did think the window was going to be a little more like the porch ones with only a half screen and slide from one side instead of the middle. With where it is I won't be opening it much. I never did the old one I had either." – Terri S., Loch Raven Village, MD | August 2, 2015 * * * * *

Greater Baltimore Location Overview

For over 30 years our location has been known for being Maryland and Delaware’s largest installer of Patio Enclosures® brand sunrooms. We’ve recently added Stanek® brand windows and patio doors to our breadth of products. Similar to our Patio Enclosures sunrooms, Stanek Windows are custom designed and custom manufactured for your home by our company. There are no middlemen – we design, manufacture, install and guarantee your windows.

Replacing the windows in your home or business is a big decision and the buying process can be overwhelming. That is why we offer a FREE no-obligation, in-home consultation with one of our experienced Design Consultants. A Stanek Windows expert will come to your home at your convenience, and go over everything with you step-by-step. During your consultation you will be able to see pictures of other homes, just like yours, that have a new Stanek Windows. Your Design Consultant will go over the variety of window styles and options we offer and provide samples of our products for you to touch, feel and see for yourself. Because we are the manufacturer, we offer a wide range of custom options including glass, size, color, hardware and much more!

Once you have decided that Stanek® brand windows are right for your home, we will take exact measurements so we can manufacture your windows specifically for your home. Unlike many replacement window companies who use stock sizes and fillers, we can make your windows to your exact specifications. Throughout the process, you'll find our team of professionals is great at keeping you informed, so you always know what our team is doing and what phase your project is in. Give us a call today!
