How to Fix Light Gaps with Roller Shades and Plantation Shutters?

Light gaps around roller shades and plantation shutters are a common issue that can disrupt your privacy and diminish the effectiveness of your window treatments in blocking sunlight. Whether you’re trying to create a cozy bedroom ambiance or enhance your home’s energy efficiency, addressing these light gaps is essential.

Why Do Light Gaps Occur in Roller Shades and Plantation Shutters?

Why Do Light Gaps Occur in Roller Shades and Plantation Shutters?

Light gaps occur primarily due to improper installation, design limitations, or misaligned measurements of your window treatments.


Roller Shades: Light gaps in roller shades often arise from the way these shades are mounted. Inside-mounted roller shades leave a small gap between the fabric and the window frame to allow smooth operation, resulting in potential light leakage.


Plantation Shutters: Plantation shutters can experience light gaps due to misaligned panels, improper fit, or natural expansion and contraction of materials over time.


Understanding the root cause is the first step toward finding effective solutions.

Simple Fixes for Light Gaps in Roller Shades

If your roller shades are letting in more light than desired, there are straightforward ways to address the issue.

Using Side Channels for Better Light Control

Using Side Channels for Better Light Control

Side channels are U-shaped tracks that attach to the sides of the window frame. These channels guide the shade fabric, eliminating gaps along the edges.


  • Benefits: They provide a seamless blackout effect, making them ideal for bedrooms and media rooms.
  • Installation Tip: Ensure the side channels are correctly aligned with the shade fabric for maximum efficiency.

Installing Blackout Shades for Maximum Light Blocking

Switching to blackout roller shades can significantly reduce light gaps. These shades are designed with thicker materials that block nearly all incoming light.


  • Pro Tip: Opt for outside-mounted blackout shades that extend beyond the window frame to cover the gaps entirely.
  • Ideal For: Spaces like nurseries or offices where complete darkness is needed.

Adding Light Blocking Strips

Light-blocking strips or adhesive tapes are an inexpensive and easy fix. Attach these strips to the edges of the shade or the window frame to close minor gaps.

Plantation shutters are a timeless and elegant window treatment option, but light gaps can compromise their functionality. Here are practical fixes:

Choosing Custom-Fit Shutters

Custom-fit plantation shutters are made to match your window’s dimensions perfectly, leaving minimal room for light to seep through.


  • Why It Works: Precise measurements ensure snug-fitting panels and frames, eliminating most gaps.
  • Expert Advice: Work with a professional installer to ensure accuracy and high-quality results.

Enhancing Plantation Shutters with Accessories

Accessories such as weatherstripping and light-blocking caulk can help reduce light leaks.


  • Weatherstripping: Place it along the edges of the shutter panels to create a tight seal.
  • Light-Blocking Caulk: Use caulk to fill small gaps around the shutter frame.
  • Magnetic Closures: These can help keep panels tightly closed, reducing movement that might cause gaps.
