Troy and Steve discuss a window replacement job we did on an entire house in Harrisburg.

  • 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. 

To see all the windows we provide, please visit our Windows page.



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.

"We love Grand Opening! We had a new front door, sliding glass doors, and a garage door installed a year ago. The doors are beautiful. The crew was courteous and quick - got the whole job done in three days. We had a couple of questions and follow-up items over the last year and they are so responsive and helpful! We will absolutely go back when we need anything else and highly recommend them!"

"Best home project we ever had done. Quality of work and the whole team was and is top notch. Windows are great, high quality, cost efficient windows.

We were quoted almost twice as much from other companies and I never felt good about the whole experience. Then this group came along and from the first visit to the end, the owner was involved and we felt like our home was important to them. Not just another job. So glad we did this!"
