Installing inside mount blinds involves fitting the blinds within the window opening, inside the frame and decorative trim. This creates a clean, finished look where the blinds are flush with the wall or trim.
Here's a step-by-step guide on how to install inside mount blinds when your window already has trim:
Understanding Inside Mount
With inside mount blinds, the measurement and installation are critical to ensure the blind fits perfectly inside the window frame, enclosed by the surrounding trim. The mounting brackets are typically attached directly to the top, sides, or back of the inner window casing – the flat surface inside the frame before the trim begins.
Installation Process
Follow these steps for a successful inside mount installation:
-
Measure Accurately:
- Measure the width of the window opening at three points: top, middle, and bottom. Use the narrowest measurement.
- Measure the height at three points: left, middle, and right. Use the shortest measurement for the height.
- Refer to your blind manufacturer's instructions for any width or height deductions they recommend for inside mount. Order your blinds based on these precise inside measurements.
-
Gather Tools:
- Pencil
- Measuring tape
- Level
- Drill and drill bits (appropriate size for pilot holes and screws)
- Screwdriver (or drill with driver bit)
- Mounting brackets (included with blinds)
- Screws (included with blinds, or use longer ones if needed for better grip)
- Safety glasses
-
Mark Bracket Locations:
- Position the blind headrail (or use the manufacturer's template) inside the top of the window casing where you want it to sit. Ensure it is centered.
- Locate the bracket locations on the top of the inner window casing. Mark these positions clearly with a pencil. Ensure the marks are level. The brackets should be placed towards the front or back of the casing, depending on the desired position of the blind and any obstructions like handles.
-
Drill Pilot Holes:
- Drill pilot holes at the marked locations. The size of the drill bit should be slightly smaller than the screw threads. Pilot holes make driving screws easier and prevent splitting the wood casing.
-
Attach Mounting Brackets:
- Align the mounting brackets with the pilot holes.
- Securely fasten the brackets to the top of the inner window casing using the provided screws and your drill or screwdriver. Ensure the brackets are firmly attached and level.
-
Install the Blinds:
- Lift the blind headrail towards the attached mounting brackets.
- Ensure that your entire blinds, including the brackets, fit into your window. (This check helps confirm proper bracket placement and blind size before final locking).
- Hook or click the blind headrail into the mounting brackets according to the manufacturer's specific instructions. There is usually a mechanism to secure the headrail in place.
-
Add Valance (Optional):
- If your blinds came with a decorative valance, attach the valance clips to the headrail.
- Secure the valance to the clips.
Tips for Success
- Always refer to the specific installation instructions provided by the blind manufacturer, as methods can vary slightly.
- Use a level to ensure your marked bracket locations and the installed brackets are perfectly horizontal. This is crucial for the blinds to hang and operate correctly.
- If mounting into drywall instead of wood casing (less common for inside mount but possible), use appropriate drywall anchors. However, the inner casing is typically wood.
- Double-check your measurements before ordering blinds. Inside mount requires precision.
Installing inside mount blinds with window trim is a straightforward process that enhances the look of your window by keeping the blinds neatly tucked within the frame.
