Double-Hung Windows: Common Issues and Expert Solutions

Double-hung windows are popular for many commercial and residential properties due to their classic style and versatile functionality. However, like any window system, they can encounter problems over time. At GC Doors, our skilled engineers specialise in diagnosing and resolving these common issues to ensure your double-hung windows perform optimally. Below, we detail some of the most frequent problems and how our expert team addresses them.

Sticking or Difficult Operation

Double-hung windows are prone to issues where they become difficult to open or close smoothly. This problem can stem from various factors, including misaligned sashes, the accumulation of dirt and debris in the window tracks, or worn-out balance systems. Over time, these issues can make your windows less functional and more challenging to operate.

Solution: Our engineers address operational difficulties by comprehensively cleaning the window tracks and applying high-grade lubricants to facilitate smooth sash movement. We also meticulously realign misaligned sashes to restore optimal function. Should the balance system be compromised, we replace it with a robust, state-of-the-art system to enhance operational ease and reliability.

Drafts and Poor Insulation

Gaps around sashes or degraded seals in double-hung windows can lead to drafts and reduced energy efficiency, which can impact indoor comfort and increase heating and cooling costs.

Solution: To rectify insulation issues, we replace damaged or ineffective weatherstripping with high-performance seals that address gaps and prevent drafts. Additionally, if the insulated glass units (IGUs) are compromised, we provide expert replacement or repair services to restore the window’s thermal efficiency and maintain a comfortable indoor environment.

Broken or Damaged Sashes

Damage to sashes, caused by weather exposure, impacts, or general wear, can affect the window’s functionality, security, and overall appearance.

Solution: Our engineers evaluate the extent of sash damage and execute precise repairs or replacements to restore functionality and security. We also reinforce compromised sashes to prevent future deterioration, ensuring long-term durability and performance.

Fogged or Cloudy Glass

Fogging or cloudiness between the panes of insulated glass units can impair visibility and diminish the aesthetic appeal of the windows.

Solution: We address this issue by replacing fogged or cloudy panes with new, high-clarity glass to enhance visibility and restore the window’s appearance. Furthermore, we repair or replace faulty seals to prevent the recurrence of fogging and ensure sustained glass clarity.

Hardware Failures

Hardware components such as locks, handles, and balance systems may experience failures or wear over time, affecting the window’s operation and security.

Solution: We tackle hardware issues by replacing malfunctioning locks, handles, and other critical components with high-quality replacements to restore proper function and security. Our engineers also repair specific hardware elements to extend service life and ensure reliable window operation.

Rotting or Decaying Frames

Wooden frames are susceptible to rot and decay, especially when exposed to moisture and insufficiently maintained, which can compromise the structural integrity of the windows.

Solution: We offer comprehensive repair services for rotting wooden frames, treating them to restore structural strength and prevent further deterioration. In cases of severe damage, we provide full-frame replacement solutions to ensure the windows’ structural integrity and longevity.
