  • Double Hung Windows one of the most popular styles of replacement windows. They have a lower and upper sash that allows for easy opening and closing.

  • Casement Windows swing out from hinges on the sides, opening vertically away from the window pane, while Awning Windows open horizontally. Both utilize a crank providing the most ventilation. 

  • Bay and Bow Windows will give your living room or den a spacious feel. Bay windows contain three separate window panels, while Bow windows have four to six window panels. 

  • Slider Windows are cost-effective, durable windows that easily glide from side-to-side open and close.

  • Picture Windows will frame the landscape outside your house, bringing beautiful views inside the home.

  • Custom Windows - if you can dream it, we can have it built. To accommodate spectacular views of a property or to enhance a specific room, we can customize a window to various shapes and sizes.

Steel Door

Fiberglass Doors look and feel just like real wood through a proprietary technology called Nickel Vapor Deposition. Fiberglass Doors provide the look of real wood with the durability of fiberglass.


Steel Doors are great for home security, as they are the strongest, most durable door on the market. They are built with 20-gauge steel, which is 49% more galvannealed steel than standard 24-gauge doors in the marketplace.


Storm Doors come in a robust or slender frame and have heavy duty stainless steel retractable screens. Choose full view, three-quarter or half-view aluminum storm door styles. 


Patio Doors

We offer Sliding Glass Patio Doors, Hinged/Swinging Patio Doors and French Patio Doors.

Satisfied Customers

Jessica Ritter,


"Just had a sliding door and three windows replaced. From the sales person, to the installation crew and project manager, everyone was amazing. They cleaned up after the job was done and showed me how to work everything. The project manager came by after completion to answer any questions and make sure everything was spotless. The door and windows are beautiful. I highly recommend Grand Opening Windows & Doors!"

Stephanie Jackson, New Cumberland

"I cannot express how pleased I am with this company. From the moment they laid out their drop cloth and the way they laid out their tools I knew that they were clean and efficient. They left my area cleaner than they found it because it is a little section off the back porch that I use for laundry and trash and such. The two gentlemen that did the work were quiet and respectful. The amount of light now that comes in that area makes me want to turn it into a little coffee nook it is just so pleasant and clean. Everything about the installation was perfect and I mean I took a magnifying glass and checked out the caulking and everything. I'm a woman that lives by myself and let me tell you getting taken advantage of by any type of home or auto repair is common. I am so impressed and thankful."

Very pleased with our overall experience. Would definitely recommend Grand Opening to anyone looking for windows or doors!"
