Installing wooden bay window shutters can completely transform the aesthetic of your home while offering functional benefits like privacy, insulation, and light control. However, the beauty and utility of these shutters depend heavily on correct installation. Even high-quality wooden shutters can underperform or look unsightly if installed improperly.
In this blog, we’ll cover some of the most common installation mistakes that homeowners and even contractors make — and how to avoid them to ensure your wooden bay window shutters are installed to perfection.
1. Incorrect Measurements
One of the most frequent and costly mistakes is inaccurate measurement. Bay windows are rarely uniform; they often have angled sides and varying depths. Assuming all windows are standard-sized can lead to shutters that don’t fit properly, resulting in gaps or misalignment.
Tip: Always measure each panel area of the bay window separately. Use a laser level and a measuring tape, and double-check all dimensions before placing an order.
2. Ignoring Window Frame Conditions
Wooden shutters are often fitted directly into or onto existing window frames. If the frames are damaged, uneven, or have old hardware protrusions, it can cause complications during installation. Uneven surfaces can lead to shutters that don’t sit flush or operate smoothly.
Tip: Inspect and prepare the window frame before installation. Sand uneven surfaces, fill cracks, and ensure the frame is square and level.
3. Poor Hardware Selection
Using incorrect or low-quality mounting hardware can impact both the stability and functionality of your shutters. Heavy wooden shutters require durable, rust-resistant hardware. Plastic anchors or weak screws can loosen over time, especially in areas with humidity or frequent use.
Tip: Choose stainless steel or solid brass hinges and fasteners. For bay windows, consider adjustable hardware that allows fine-tuning during installation.
4. Misaligned Panels
Even if your measurements are accurate, misalignment during the mounting process can throw off the symmetry of the shutters. This affects not only the look but also the operation — panels may rub, stick, or hang unevenly.
Tip: Use a level during every step of installation. Pre-mark all drilling points and check alignment after each panel is installed.
5. Not Allowing for Wood Expansion
Wood naturally expands and contracts with changes in temperature and humidity. If shutters are installed too tightly within the bay frame without any room for movement, they may warp, crack, or become difficult to open over time.
Tip: Leave a small clearance around each shutter panel to accommodate seasonal changes. Also, consider pre-treating the wood with sealant to reduce moisture absorption.
6. Skipping Professional Help
While DIY installation may seem cost-effective, bay windows are complex by nature. The angles, depths, and multiple panels require precision that’s hard to achieve without experience.
Tip: If you’re unsure, consult a professional installer—especially for custom wooden bay window shutters. A well-done installation will protect your investment and ensure the shutters last for decades.
Conclusion
Wooden bay window shutters are an elegant and timeless window treatment, but installing them requires attention to detail. From accurate measurements to choosing the right hardware and allowing for natural material movement, small missteps can lead to big problems. By avoiding these common mistakes, you’ll ensure your shutters enhance your space in both form and function.
If you're planning a new installation or upgrading your current shutters, take the time to do it right—or partner with a professional who can.
