Everything You Need to Know About Replacing a Double Hung Window

Choosing to replace double hung window units is one of the most popular home improvement projects for Pennsylvania homeowners. These windows feature two operable sashes that slide vertically, allowing for maximum ventilation and easy cleaning.

Quick Guide to Double Hung Window Replacements

  • When to replace: If you notice drafts, condensation between panes, or difficulty opening the sash.
  • Why choose double hung: They offer superior airflow (opening top and bottom) and tilt-in sashes for easy cleaning from inside the house.
  • Energy savings: Modern units significantly reduce thermal transfer, lowering heating and cooling costs.
  • Property value: New windows offer one of the highest returns on investment (ROI) for exterior renovations.

When is the right time for replacing a double hung window?

Most high-quality windows last 20 to 25 years. However, if your frames are rotting or the glass feels cold to the touch in winter, you should consider double hung window replacements sooner rather than later. Ignoring these signs leads to higher energy bills and potential water damage inside your walls.

 

Should you replace all windows at once?

While replacing a double hung window in a single room solves an immediate problem, doing the whole house at once ensures aesthetic consistency. It also allows for a more efficient double hung window installation process, often saving you money on labor costs in the long run.

How to Choose the Best Replacement Window Contractor

 

Material Matters

The material you choose impacts both the price and the lifespan of your windows. Before making a final decision, review this value comparison of wood, fiberglass, and vinyl to see which fits your budget and maintenance preferences.

 

Maximizing Energy Efficiency

Lancaster winters can be brutal. To keep your home cozy, you need to identify the best energy-efficient window options available. Look for Low-E glass coatings and argon gas fills to ensure your new double hung window installation provides the best thermal protection.

 

How the Pros Approach Double Hung Window Installation

Proper double hung window installation requires precision and attention to detail. A poorly installed window, no matter how expensive, will leak air and water. Here is how the experts handle the process to ensure a perfect fit:

  1. Precise Measurement: Measurements are taken at three points, top, middle, and bottom, to account for any slight shifting in the home’s structure.
  2. Sill and Frame Preparation: After removing the old unit, the opening is cleaned and inspected for any hidden rot or damage that needs repair before the new double hung window replacements arrive.
  3. Flashing and Waterproofing: High-quality flashing tape is applied to the sill to create a moisture-proof barrier.
  4. Setting the Unit: The new window is placed into the opening. Shims are used to ensure the unit is perfectly level, square, and plumb.
  5. Securing the Frame: Screws are driven through the side jambs into the structural framing of the house.
  6. Insulation: Expanding foam or fiberglass insulation fills the gaps between the window frame and the house framing to eliminate drafts.
  7. Exterior Sealing: Professional-grade caulk is applied around the exterior perimeter to prevent water intrusion.
  8. Interior Finishing: The interior trim is reinstalled or replaced, leaving the area looking brand new.
