Pella Casement Windows Common Problems

Casement windows hinged to the frame and opening much like doors represent the oldest form of moveable windows. However, over time they can face various issues, often with the window sash, frame, or hardware.

As a homeowner, understanding these potential problems is essential in making an informed decision about the type of windows suitable for your home. While Pella offers high-quality casement windows, some common issues may still arise, warranting your attention.

Casement Window Mechanics and Common Issues

Pella casement windows work through a combination of hinges, crank, and gear system, allowing each window panel, or casement sash, to open and close independently. However, these moving parts require regular maintenance to ensure their proper functioning. Failure to do so can lead to various problems, including windows not closing, becoming stuck shut, broken window cranks, sagging hinges, lock problems, and damaged weatherstripping.

Some of these issues could be due to dirt or debris stuck in the hinges or sash, stripped gears in the crank mechanism, lack of lubrication, or simply aging hardware.

Pella Casement Windows: An Overview of Issues

The article on Brennan Enterprises' blog titled "Casement Window Problems" provides the most common problems with Pella casement windows. Windows might not close completely due to hindered hinge arms or debris or become stuck shut, potentially pointing to damaged hinge arms or an engaged lock. Broken window cranks can result from various factors, such as stripped crank handles, rust, or built-up dirt in the gear mechanism. 

Furthermore, hardware wear and tear can cause sagging hinges, making the frame bow or warp. Lock mechanisms might face problems due to misaligned lock parts or lack of lubrication. Lastly, worn weatherstripping, often due to frequent window usage, can lead to drafts or moisture leaks. However, rest assured that most of these problems can be resolved with regular maintenance, professional help, or potentially through Pella's manufacturer's warranty.

Pella Casement Window Issues

Pella Corporation, a reputable name in the window industry, is known for its range of high-quality products. While their casement windows have largely satisfied customers, there have been reported issues that you should be aware of.


Condensation transforms vapor into liquid, usually occurring when warm, moist air contacts a cooler surface, like your window pane. You might notice this phenomenon after a hot shower or during cooking as your windows "sweat". Usually, this moisture can be easily wiped off. However, the real challenge arises when condensation forms between window panes, an area out of reach.

Condensation between window panes, a sign of seal failure, is indeed a problem. This indicates that the protective barrier maintaining the insulation and effectiveness of your windows is compromised. The warm, moist air that makes its way between the glass panes condenses into droplets that can't be wiped away. The result is a permanent, foggy appearance, which is not just aesthetically displeasing but also degrades the efficiency of your windows. 

Addressing this issue depends on the severity and specifics of each situation. You may claim repairs under your window warranty, especially if the seals decay prematurely. If the issue persists, professionals can employ methods such as injecting a condensation-eliminating chemical between the panes or replacing the glass or the entire window, if necessary. To prevent condensation, maintaining a balanced indoor humidity level is crucial.

Wood Rot

Wood rot, a form of fungal decay, represents a significant hazard to the performance and lifespan of your windows. The problem occurs when moisture consistently gathers in one area, creating a nurturing environment for fungal spores to flourish. When this moisture issue is combined with the cellular structure of the wood, rot begins to set in, degrading the window's integrity and, over time, posing a risk to the surrounding structure. 

The signs of wood rot can be deceptive, often hidden under an aluminum cladding, as with the Pella Corporation's Architect and Designer Series windows. By the time the rot becomes apparent, significant damage may have already occurred, necessitating costly repairs or replacement.

You must become familiar with its signs to detect wood rot early and prevent costly outcomes. Notice if your windows have become drafty, indicating gaps in the frame or sash, or if the window sashes are rattling, a sign of the cellulose in the wood shrinking due to rot. When touched, wood damaged by rot feels soft, almost like foam. 

Other symptoms include paint bubbling due to moisture-induced swelling and difficulty operating the window due to warping. Check all parts of the window, from the trim and brick molding to the window sill, frame, and sash. You can identify and address these issues by remaining vigilant before they escalate.

Upon identifying wood rot, immediate action is crucial. Depending on the extent of the rot, you may need to repair or replace the window. Furthermore, inspecting the wall where the damaged window exists for any signs of rot is essential. While dealing with the immediate issue, you should also consider preventative measures. 

Choosing windows made from durable materials like Fibrex or high-performance vinyl could be beneficial, especially in regions with common wood rot. Remember, wood rot is a symptom of a larger moisture problem. If such issues persist, consulting an expert can help manage the situation effectively, saving you time and money in the long run.

Peeling Paint

Peeling paint is another issue often reported by homeowners. The paint on the window frames can start to peel over time due to exposure to the elements. Regular maintenance, such as timely painting and sealing, can help avoid this issue.

Other Considerations

Pella's pricing model for their casement windows is another factor worth considering. While they offer a great product, they are on the higher end of the pricing spectrum. The pricing can be viewed directly on Pella’s website under their casement window section.

It's worth noting that despite these problems, Pella is a quality product, and the issues reported are minimal compared to the overall satisfaction reported by users. However, if you seek alternatives, other brands, such as Andersen, Simonton, and even we offer our own high-quality casement windows, often at a more competitive price.

In conclusion, being aware of these potential problems will enable you to make an informed decision when purchasing casement windows. It's essential to consider factors such as proper installation, regular maintenance, and the overall cost while choosing the right product for your needs. Pella, with its reputable name and proven quality, remains a strong contender in the world of casement windows, notwithstanding the occasional issues that may arise.
