Interior window blinds have become a popular choice among homeowners for their aesthetic appeal, functionality, and energy-efficient benefits. However, they could develop certain problems that may affect their performance and functionality.

As a San Antonio window treatment company since 2004, Blinded by Delight has helped thousands of homeowners transform their interiors with custom blinds, shutters, and shades. 

While we strive to provide you with the right solution for your home, we also want to educate you on common problems you may encounter with your new blinds. 

It is important you identify these issues and address them sooner rather than later to avoid further damage and help your blinds last longer.



Top 5 Problems With Interior Window Blinds

Let's dive into the top five common problems with interior window blinds and how to fix them, so you can maintain your window treatments and help them last longer.


1. Broken Slats

Over time, the slats on your interior window blinds may become brittle and crack or snap. This is a common problem with plastic and vinyl blinds, especially if they're exposed to direct sunlight and extreme temperatures.

To fix this problem, you can replace broken slats with new ones or have a professional repair service do it for you. For wooden blinds, you may need to sand them down and repaint or re-stain them to restore their beauty and functionality.

This common issue typically comes with old age of your window coverings. However, you can help your blinds last longer by regularly cleaning and providing routine maintenance. You also want to ensure you handle your blinds with care when opening or closing them to minimize broken slats and damage. 

2. Tangled Cords

Another common problem with interior window blinds is tangled cords. This can happen when the cords get twisted or knotted, making it difficult to operate the blinds smoothly.

To untangle the cords, you should first remove the blinds from their mounting bracket, then lay them on a flat surface. Carefully untangle the cords by pulling them apart, making sure not to break them. If you have trouble fixing tangled cords, you can always seek professional help. 

Avoid tangling the cords of your blinds by carefully using them when opening and closing your blinds. This will help keep the cords straight and avoid becoming a tangled mess.

3. Malfunctioning Motor

Some interior window blinds are designed to function automatically with the help of a motor that raises and lowers them. This motor can develop problems over time, such as overheating, burnout, or mechanical failure.

To fix a malfunctioning motor, you should first check if there are any problems with the power supply, then inspect the motor for any visible damage or loose connections. If you can't find the problem, you'll most likely want to contact the company that installed your blinds to have them come and fix the motor. 

4. Warping or Bending

Blinds made of certain materials like wood or aluminum may warp or bend over time due to humidity, temperature fluctuations, or exposure to moisture. This can cause the slats to become uneven, preventing the blinds from operating smoothly.

To fix this problem, you can adjust the slats manually or have a professional straighten them out. Prevention is key to avoiding warped or bent blinds, so it's best to avoid placing them in damp or humid areas.

If slats are extremely warped, you may want to consider replacing them to help your blinds function better and last longer.

5. Dust and Grime Buildup

Like any fixture in your home, interior window blinds can accumulate dirt, dust, and grime over time, making them look discolored and dingy.

To clean them, you can use a microfiber towel, dish soap, and warm water to wipe down the slats gently. Avoid using harsh chemicals or abrasive materials that could damage the blinds' finish. Regular cleaning and maintenance can help your blinds last longer and keep them looking brand new.


Maintaining Your Blinds And Helping Them Last Longer

Now that you know the five most common problems with interior window blinds, you can take the right steps to maintain them, improve their functionality, and help them to last longer. 

When inspecting your blinds, remember to look out for

  1. Broken slats
  2. Tangles cords
  3. Motor malfunctioning
  4. Warped or bent slats
  5. Dust and grime buildup

Once you've identified any issues with your blinds, you can properly address them to avoid further damage and keep them looking brand new.
