Window Parts: How Often Should They Be Replaced?

Posted February 16, 2025

Curious about which window parts need regular replacement? This guide covers essential components like weatherstripping, screens, and hardware. Learn their roles, how often they need replacement, and tips for maintaining them!

Key Takeaways

  • Weatherstripping and caulking require regular replacement to prevent air leaks and maintain energy efficiency, with exterior caulking needing attention every five years.
  • Window screens, when well-maintained, improve air quality and protect against pests, but should be inspected annually and replaced if damaged.
  • Cranks are among the most frequently replaced window hardware components, although other parts, like sliding window rollers or double-hung window pivot bars, may also require replacement.
  • If the glass is cracked or the sashes are warped, you may want to consider a retrofitting project. If the frame is damaged, you’ll have to replace the entire unit.
  • Regular inspections and timely replacements of window hardware, locking mechanisms, and trim are essential for ensuring that everything stays in line and maintaining window functionality and security.

1. Weatherstripping and Caulking

Weatherstripping and caulking seal gaps around your windows, preventing air leaks and improving energy efficiency. Weatherstripping is made of materials like adhesive foam or rubber strips to cover the edges of windows and doors, being applied to movable parts.

Over time, weatherstripping and caulking can deteriorate due to exposure to the elements, requiring periodic replacement. In fact, these two insulating materials are the most frequently replaced window components.

Caulking seals cracks and joints with flexible materials like silicone or latex, and is applied only to fixed parts. Silicone-based products are recommended for exterior caulking due to their durability and flexibility. Interior caulking is often made from latex and should be replaced when it shows signs of wear or damage.

Replacement frequency: Exterior caulking generally needs attention every five years (or more, depending on caulk quality, climate, and other factors), with an initial check one year after installation. Weatherstripping needs to be replaced every 5-7 years or as needed. You’ll know it requires replacement if it is cracked, loses its flexibility, or looks worn out.

Keeping up with weatherstripping and caulking maintenance prevents larger issues and ensures your windows perform well, so don’t forget to check them once in a while! For more details, check out our guide on where not to caulk around windows!

2. Window Screens

Window screens serve as a protective barrier, keeping pests out while allowing fresh air to flow into your home. However, window screens are prone to damage from various factors, including weather conditions, especially if they’re not made from durable materials.

If your window screen has just a tiny hole, you can probably fix it yourself and avoid replacing the entire screen. Nonetheless, homeowners usually prefer replacing it as soon as possible to avoid any issues in the future. If you have Magic windows, you can replace the screens simply by shipping the screen cartridges to us, and we’ll take it from there!

Well-maintained screens last longer, reducing the need for frequent replacements. Therefore, make sure to clean them regularly to avoid dirt buildup. Still, even with regular care, screens can become brittle or develop rips, so you should inspect them at least 2-3 times a year.

Replacement frequency: Homeowners generally replace their window screens every 5-7 years.

3. Window Hardware

Window hardware encompasses various components that make it possible to open and close the window. Hardware parts also play an important role in ensuring a window’s security and energy efficiency. These include sash locks, tracks and rollers, casement or awning window operators, hinges, and balances, each playing a vital role in window functionality.

Different types of windows, such as casement windows, double-hung, sliding, and awning windows, require specific hardware to operate smoothly. A quick view of your windows during regular maintenance can help you spot damaged hardware, and you can check if replacement units are in stock at your local home improvement store.

Different Types of Window Hardware

Crank mechanisms (also called casement window or awning window operators) make it possible for you to open windows – that is, if they’re not broken! Unfortunately, cranks break all the time, and many homeowners find themselves in need of a replacement system sooner rather than later.

Hinges, available in various sizes, ensure that awning and casement windows open and close properly, so they need to be inspected and lubricated regularly – this can slightly extend their lifespan, but they may still require replacement because of wear and tear.

Sash locks secure the window sashes to the frame, offering security and preventing drafts. Check these locks regularly and replace them if they become loose or damaged.

Other window hardware that may require replacement or repairs include:

  • Sliding window tracks – if the tracks bend, you won’t be able to open and close the window, so you’ll have to repair them.
  • Sliding window rollers – if the rollers break, the window won’t slide seamlessly along the track
  • The pivot bar in double-hung windows is located in the lower sash and is responsible for the window’s tilt-in function.
  • The tilt latch in double-hung windows keeps the window in the upright position.
  • Pivot lock shoes in double-hung windows, also known as balance shoes, are responsible for locking the window into place when it’s tilted.
  • Jamb liners allow the sashes to slide up and down and seal gaps between the sashes and the frame.

Replacement frequency: Window hardware often has the same lifespan as the window, although some components may require replacement after 10-15 years of use, depending on their quality and how often the window is opened and closed.

4. Glass Panes and Sashes

Glass panes and sashes are integral components of a window, providing structural support, energy efficiency, and aesthetic appeal.

You may have to replace the glass if it’s broken or cracked or if it has condensation between panes, which indicates seal failure. Additionally, homeowners often replace the glass if they want to upgrade from single-pane to double-pane windows. The sashes – the movable parts that hold the glass – may require replacement if they’re warped or cracked and the window doesn’t operate as needed.

Window sashes can often be replaced without replacing the entire window – this is a cost-effective solution for damaged/broken glass or warped sashes, but only if the frame is in good condition. In this case, you’d be considering a retrofitting project.

Replacement frequency: Glass panes and sashes should last as long as the window, but you may need to replace them if you notice any signs of wear and tear or if the glass breaks.

5. Locking Mechanisms

Locking mechanisms are crucial for window security and functionality. Various types of locks are available, including sliding, sash, keyed, and bolt locks, each designed for specific window types. Smart locks, which operate through keypads or remote controls, provide enhanced security features compared to traditional locks.

Check locks regularly and replace them if damaged or worn out – this way, you’ll make sure your home remains safe and secure! If you need to replace them, consider installing multi-point locking systems, which secure windows at various points and protect your home against break-ins. Additionally, install window restrictors as a childproofing measure to limit how far windows can open.

Replacement requirements: Locking mechanisms usually last 10-15 years, although you may have to replace them more frequently if you live in coastal or humid areas, especially if the locks are made of aluminum.

6. Window Trim

Window trim not only enhances the visual appeal of your home but also protects against environmental damage and reduces energy costs by sealing gaps. However, window trim can suffer from rot and water damage, especially if not properly maintained or installed incorrectly. Therefore, like for other window parts, regular inspections and maintenance are essential to prevent any issues.

Window trim is made of different materials, including wood and vinyl, each with its own maintenance requirements. For instance, wood trim may require painting to prevent weather damage, while vinyl trim requires minimal maintenance.

If you’re replacing your windows, it’s an excellent opportunity to also inspect and possibly replace the window trim, especially if there are signs of water leakage or damage. Well-installed window trim can improve your home’s energy efficiency and overall appearance.

Replacement frequency: Window trim usually lasts up to 50 years, depending on exposure and upkeep. Therefore, in some cases, homeowners replace their windows but keep the window trim. Nonetheless, it needs to be inspected thoroughly because if it’s damaged, it can cause water and air leaks.

7. Window Frame

The window frame serves as the structural foundation of a window, ensuring all components are securely aligned and supported. If the frame is worn out, damaged, cracked, or warped, it can lead to various issues, including drafts, difficulty in operating the sash, reduced energy efficiency, and damage to surrounding structures.

Replacing a window frame implies replacing the entire window unit, including the sash, glass panes, and hardware. It also implies that you’ll have to replace the sill, the jambs, the head, and the mullions.

Replacement frequency: Every 20-30 years, depending on window frame quality, the climate in your region, and maintenance.
