Old windows bring a unique charm to any home, showcasing their rustic design, high-quality materials, wavy glass, and divided lite patterns. Over time, however, these windows can suffer from cracks, chipped paint, leaks, and sagging. Before you decide to replace your antique windows, it’s essential to consider the following aspects.

Window Restoration vs. Window Replacement

Although it might seem more straightforward to replace old windows, there are several reasons to preserve them. Not only do they possess a distinctive appearance, but their materials are also of higher quality, safer, more durable, and longer-lasting. Furthermore, old windows were designed for repair, while modern replacement windows are meant to be replaced.

Maintaining old windows requires effort and attention. Below is an overview of the steps involved in repairing vintage windows and the process of restoration.

The Window Restoration Process

The restoration and repair process for old windows can range from relatively simple to more complex, depending on the window’s condition. It’s always best to consult a professional for old window renovation projects, but here’s what you can expect during the process.

Beginning with the Window Sash

The window sash, which holds the glass, is usually made of wood for old windows. If not regularly painted or treated, the wood can swell, crack, and rot, compromising the window’s integrity. Many old windows require breaking a paint seal for the first-time restoration. It’s crucial to let professionals handle paint-related tasks, as windows made before 1978 may contain lead paint, which poses significant health risks.

Stops, which are wooden trim pieces that direct the window’s path for opening and closing, will be removed. After detaching the sash and glass from the frame, the weights and pulleys are cleaned or replaced to ensure smooth operation. The sash is then stripped, sanded, primed, and painted. To improve energy efficiency, insulation can be added to the sash exterior.

Working on the Glass

Professionals will safely remove the glass by loosening the seal with heat and a specialized chisel. After removing the glazier points, a new glazing compound is applied to secure the glass in the frame. The window is then reassembled with added insulation and protective coatings to prevent rot and cracks.

Window Restoration: Pros and Cons

Before embarking on a window restoration project, weigh the pros and cons to determine the best course of action.


Restored windows provide insulation comparable to new vinyl windows and are made of longer-lasting materials. Unlike vinyl windows, old windows can be repaired, making them more cost-effective and environmentally friendly. Restoring original windows helps maintain the classic look and historical value of a home, preserving its charm and legacy.


Restoring old windows can be time-consuming, labor-intensive, and expensive, particularly when hiring a professional and procuring the necessary materials. Some materials and equipment may be challenging to find, especially if you want to adhere to strict historical guidelines. Additionally, lead paint exposure is a risk for homes built before 1987, and the extra precautionary steps needed to protect against this hazard can further slow down the process.

Window Restoration: Additional Considerations

Before beginning a window restoration project, take the following factors into account:

  1. Historic Preservation Guidelines: If your home is located in a historic district or has specific preservation requirements, you may need to comply with local regulations when restoring your windows. Consult with your local historic preservation office for guidance on proper restoration techniques and materials.
  2. Energy Efficiency: Although restored windows can provide similar insulation as new windows, additional steps may be needed to improve energy efficiency. Consider adding weatherstripping, insulating window film, or storm windows to maximize energy savings and enhance your home’s comfort.
  3. Customization: When restoring antique windows, you have the opportunity to customize them to suit your preferences. You can choose to maintain the original appearance or modify the design to match your home’s style or improve functionality.
