Inside vs. Outside Mount: Choosing Window Treatment Installation

When selecting new custom window treatments for your Los Angeles or Ventura County home, one of the fundamental decisions you'll encounter is whether to opt for an inside mount or an outside mount. This choice significantly impacts the aesthetics, functionality, and even the light control of your shutters, blinds, or shades. At 818 Shutters & Shades, we understand that this can feel like a complex decision. Our goal is to demystify the process and help you choose the best installation method for your unique windows and personal style.

Let’s dive into the specifics of both inside mount and outside mount installations, examining their benefits, considerations, and how they suit various window types and design preferences. Understanding these differences is key to ensuring your new window treatments not only look stunning but also perform exactly as you envision.

What is an Inside Mount Window Treatment?

An inside mount refers to the installation of your window treatment within the recessed window frame itself. The blinds, shades, or shutters are fitted snugly inside the casing, flush with the window sill or frame. This method provides a clean, streamlined look that often highlights the architectural details of your windows.

Pros of Inside Mount Installation:

• Clean and Integrated Look: Since the treatment fits within the window frame, it creates a very tidy, built-in appearance. This is often preferred for a minimalist or contemporary aesthetic.
• Highlights Window Trim: If your windows have beautiful decorative trim, an inside mount allows that trim to remain fully visible, enhancing your home's character.
• Space-Saving: Because the treatment doesn't protrude beyond the window frame, it's an excellent choice for rooms where space is at a premium or where furniture might be placed close to the windows. This is particularly relevant in some of the more compact living spaces you might find in urban areas of Los Angeles.
• Optimal Light Control (with precision): When measured and installed correctly, inside mount treatments can minimize light gaps around the edges, offering superior light control and privacy. Custom-made treatments from 818 Shutters & Shades are precisely measured for this very reason.
• Security and Safety: By recessing the treatment, it's less likely to be snagged or damaged, and cords (if applicable) are kept closer to the window, potentially reducing hazards for children and pets.

Considerations for Inside Mount:

• Requires Sufficient Window Depth: The most critical factor for an inside mount is having enough unobstructed depth within your window frame for the chosen treatment to fit. Not all window treatments, especially certain types of blinds or shutters, will fit in shallow windows.
• Visible Window Frame Obstructions: Any handles, cranks, or security sensors within the window frame will need to be accounted for, as they can obstruct the installation or operation of an inside mount treatment.
• Exact Measurement is Crucial: Because the treatment must fit precisely within the frame, accurate measurements are paramount. A slight error can lead to light gaps or an inability to install the treatment properly. This is where 818 Shutters & Shades' professional measurement services truly shine.
• Less Insulation: While offering good light control, an inside mount can sometimes allow more air infiltration around the edges compared to an outside mount that covers the entire window opening.

What is an Outside Mount Window Treatment?

Conversely, an outside mount involves installing your blinds, shades, or shutters outside the window frame, typically extending beyond the trim. The treatment is mounted either on the wall above the window or directly onto the window trim itself, overlapping the window opening on all sides.

Pros of Outside Mount Installation:

• Enhanced Light Control & Privacy: By overlapping the window opening, outside mount treatments significantly reduce light leakage around the edges, providing superior room darkening and privacy. This can be a huge benefit for bedrooms or media rooms in sun-drenched Southern California homes.
• Covers Imperfections: If your window frames are uneven, unattractive, or you want to conceal outdated trim, an outside mount can elegantly hide these imperfections.
• Appears Larger: Mounting the treatment higher and wider than the window can make a window appear larger and taller, creating a more dramatic and expansive feel in a room.
• No Depth Requirement: Unlike inside mounts, outside mounts don't depend on the depth of your window frame, making them a versatile solution for practically any window, especially those with shallow sills or obstructions.
• Accommodates Any Treatment: This mounting style allows for the installation of virtually any type of window treatment, including those that might be too bulky for an inside mount, such as certain shutter styles or layered drapery.
• Improved Insulation: By covering more of the wall space around the window, outside mount treatments can offer slightly better insulation against heat transfer, which is always a plus in our varied Los Angeles climate.

Considerations for Outside Mount:

• More Prominent: An outside mount is a more dominant feature in a room, as it covers more wall space. Ensure this aligns with your desired aesthetic.
• Can Conceal Trim: If you have beautiful window trim that you wish to showcase, an outside mount will unfortunately cover it.
• Requires Wall Space: You’ll need sufficient flat wall space above and around the window opening for proper installation.
• Potential for Furniture Collisions: If furniture is placed very close to the window, an outside mount might interfere or create an awkward protrusion into the room.
• Measuring for Overlap: While less restrictive than inside mount, precise measurements are still needed to determine the ideal overlap for aesthetics and light control. Our experts at 818 Shutters & Shades ensure these measurements are perfect.

Which Mount is Best for Your Southern California Home?

The 'best' mounting style truly depends on your specific windows, your aesthetic preferences, and the practical needs of each room. Here are a few scenarios to help guide your decision:

• For a Clean, Unobstructed Look: If your windows have deep sills and attractive trim that you want to highlight, and you prefer a minimalist design, an inside mount is likely your best bet. Think of custom plantation shutters perfectly fitted into a window recess.
• For Maximum Light Control and Privacy: If room darkening is a top priority (essential for those bright California mornings!), or you want to make a window appear larger, an outside mount will deliver superior results. This is often the preferred choice for blackout shades in bedrooms.
• For Shallow Windows or Obstructions: If your window frames lack sufficient depth for an inside mount, or if there are handles, cranks, or alarm sensors that would interfere, an outside mount provides a straightforward and effective solution.
• For Unique Window Shapes: While some uniquely shaped windows can accommodate inside mounts, more often an outside mount offers greater flexibility for installation when dealing with arches, circles, or other non-standard window designs.
• Considering Shutters: Custom shutters often lend themselves well to both mounting styles. An inside mount creates a flush, architectural look, while an outside mount can offer a bold, framed statement while still providing exceptional light control and privacy.

Professional Installation Matters for Both Mount Types

Regardless of whether you choose an inside mount or an outside mount, professional installation is crucial. Precise measurements are the foundation of any successful window treatment project, especially when considering the nuances of internal vs. external fitting. Incorrect measurements can lead to light gaps, treatments that don't fit, or an unprofessional appearance.
