Installing Blackout Curtains over Window Blinds

Having both blinds and blackout curtains can provide the best of both worlds for managing light and privacy in your home. Blackout curtains installed over existing window blinds unite the core functionality of each - blocking visibility from outside while still allowing adjustable light control. When layered properly, this dynamic duo can transform any room into a serene, theatrical hideaway.

But accomplishing the perfect pairing requires some forethought and strategic planning. By the end, your windows will finally achieve that crisp, polished look you've been envisioning.

Benefits of Adding Blackout Curtains Over Blinds

Before jumping into the installation process, let's first review why layering curtains over blinds can be so advantageous:

• Enhanced light control - Blackout curtains provide supplemental light blockage compared to blinds alone.
• Increased privacy - Blackout fabrics prevent any visibility into a room, making them ideal for bedrooms and nurseries.
• Improved insulation - The thickness and density of most blackout curtains improves temperature regulation.
• Versatile installation - Curtains can mount on rods, tension mounts, adhesive hooks, and more for flexible positioning.
• Design flexibility - With endless color, pattern, and fabric options, it's easy to match any decor style.

Assessing Window and Blind Compatibility

While blackout curtains pair well with most blind types, first confirm your specific windows and existing blinds can support adding curtains:

• Blind style - Venetian and vertical blinds generally accommodate curtains, while roller blinds may need extra planning.
• Available space - Check adequate clearance between the blind's top edge and the window frame or ceiling to fit a curtain rod.
• Protrusion - Blinds extending far from the wall interfere with curtain flow and hang.
• Window depth - Inside mount blinds with curtains require ample frame depth to fit both treatments.

Installation Options: Drilling vs Non-Drilling

Once window compatibility is confirmed, decide on your preferred installation method. Both drilling and non-drilling options work for mounting curtain rods over blinds:

• Curtain rod installation - Requires drilling into walls or window frames to secure metal or wood rod brackets.
• Tension rod installation - Suction-cup tension rods fill the window gap to hang curtains without drilling.
• Adhesive hook installation - Self-adhesive hooks stick onto window frames or walls to hold curtains.
• Magnetic rod installation - Magnetic curtain rods adhere to metal surfaces around windows without drilling.

How to Hang Blackout Curtains Without Drilling

• Tension rod - Use an adjustable tension curtain rod sized slightly wider than your window inside the frame. The tension against the walls creates a tight fit to hang curtains.
• Adhesive hooks - Apply heavy-duty adhesive hooks onto the window molding or surrounding walls. Clip curtain rings or backings over the hook ends for hanging.

Preparing the Window and Blinds

With the installation technique decided, now prep the physical space. Proper measurements and blind adjustments ensure your curtains hang beautifully.

Cleaning and Assessment

Start by thoroughly cleaning both window and blinds:

• Wash window inside and out with glass cleaner.
• Dust blinds with brush or vacuum attachment.
• Check blinds function properly - raise, lower, tilt.
• Address any blind damage before adding curtains.

Measuring

Precision measurements allow perfect blackout curtain sizing:

• Width - Precisely measure window frame width for exact curtain panel dimensions.
• Height - Measure distance from top of blind to ceiling or window header.
• Depth - For inside mounts, confirm window frame depth suits both treatments.

Installing the Curtain Rod

Once prepared, it's time to mount the key functional component - the curtain rod bracket system. Carefully follow the manufacturer's instructions for your specific rod style.

Rod Considerations

• Style - Choose straight, bowed, or decorative rods to match your room.
• Size - Select a rod length spanning the entire window or window wall for a flawless aesthetic.
• Material - Match metal and finial finishes to your existing decor.
• Diameter - Wider rods suit heavier blackout fabrics.

Mounting Placement

Identify the optimal rod location:

• Height - Mount just below the ceiling or existing cornices for adequate curtain clearance.
• Projection - Set sliding doors and windows slightly wider than the frame to enable full curtain draw.
• Alignment - Hang multiple rods in identical positions for symmetrical styling.

Securing the Rod

Attach to the underlying surface securely:

• Center brackets evenly spaced for optimal support.
• Use wall anchors in drywall or plaster to reinforce the rod.
• Confirm screws penetrate wood window frames solidly.
• For side mounting, angle screws towards window frame top.

Hanging the Blackout Curtains

Moving onto the exciting part - it's time to mount your gorgeous new blackout curtains! Complete accurate measurements first for perfect light blockage.

Measuring and Cutting Panels

• Use a cloth measuring tape for accuracy.
• For outside mount rods, measure curtain width equal to rod length.
• Inside mount rods require exact window frame width.
• Measure curtain height from rod pocket to desired floor clearance.
• Cut panels to specification using sharp scissors.

Creating Pleats

• Plan spacing and width for symmetrical pleats.
• Iron creases along measured marks.
• Secure pleat creases using fabric glue.
• Top stitch pleats using coordinated thread.

Hanging Panels

• Slide rings or grommets over the rod, evenly spacing for proper hang and draw.
• Smooth any uneven areas or wrinkling top to bottom.
• Loosely tie back panels when not in use to maintain shape and flow.

Optional Enhancements

Weighted Hem

• Insert drapery weights into bottom hems touching floor for improved light blockage.
• Conceal chain weights in rod pocket hems to prevent floor damage.

Insulating Lining

• Layer curtains using complimentary patterns and textures.
• Attach thermal blackout lining to boost temperature insulation.

Velcro Connectors

• Apply matching Velcro strips to blind and curtain tops.
• Connect strips to keep treatments neatly stacked.

Making Final Adjustments

Before admiring your window transformation, address any adjustments for an impeccable setup:

• Check for light leakage at edges using a flashlight.
• Reattach any loose areas, ensuring smooth flat blocking.
• Test blind operation without interference.
• Trim curtain length if puddling excessively.

Maintaining Your Blackout Curtains

• Gently vacuum using soft brush attachment.
• Follow manufacturer instructions for fabric washing.
• Steam or press on low heat to smooth wrinkling pleats.
• Reapply weighted hems if curtains begin rising over time.
