Inside mount vs. outside mount — choosing before you buy
The mount style determines how the blind or rod is positioned relative to the window frame. This needs to be decided before buying the blinds because it affects the measurements:
Inside mount
The blind bracket is installed inside the window frame opening. The blind sits recessed within the frame, and the window trim is fully visible. This gives a clean, built-in look. Requirements:
- The window frame must have at least 1.5 inches of clear, flat depth inside the frame to accommodate the bracket (many windows have 2 to 3 inches)
- The window opening must be square — an out-of-square opening will leave visible gaps at the sides of the blind
- Inside mount blinds are ordered to the exact window opening width; the blind mechanism takes up a small amount of space so the manufacturer deducts a small amount from the ordered size
Outside mount
The bracket or rod is mounted on the wall above or beside the window frame. Advantages:
- Works for any window regardless of frame depth
- Can cover more of the window including the frame — useful if the frame is in poor condition
- Curtain rods are almost always outside mount; they typically extend 4 to 6 inches past each side of the window frame so curtains can be drawn fully clear of the glass
- Makes windows appear larger by positioning the rod close to the ceiling
For outside mount blinds, you measure and order to the size you want to cover — typically 4 inches wider than the window opening on each side and 4 to 6 inches above the frame top.
Types of window treatments and installation notes
Roller blinds and zebra shades
The most common installation request. One bracket on each side of the window, the roller slots in between. Roller blinds are available as inside or outside mount; most come with hardware included. Installation is 10 to 15 minutes per window for a standard drywall wall.
Roman shades
Similar to roller blinds but fabric-based. The hardware is slightly more involved — a headrail that must be level and securely anchored since the fabric weight and cord tension put more stress on the brackets than a roller. Most Roman shades are inside mount.
Venetian and aluminium slat blinds
Standard horizontal slat blinds with a tilt rod and lift cord. Installation is similar to roller blinds. These are heavier than roller blinds and the brackets must be rated for the weight — included hardware on most name-brand blinds is sufficient for drywall mounting into studs or with appropriate anchors.
Cellular and honeycomb shades
Popular for Calgary homes because the cellular structure provides additional insulation — relevant given Calgary's -25°C winter temperatures. Single-cell, double-cell and triple-cell options are available; triple-cell provides the best insulation. Top-down/bottom-up cellular shades have two headrails and require slightly more time to install correctly.
Curtain rods and drapery panels
A curtain rod requires two or three brackets (two ends, sometimes a centre support for long spans) mounted on the wall above the window. Key considerations:
- Bracket height — typically 4 to 6 inches above the window frame top, or closer to the ceiling for a dramatic look. Decide this before installation.
- Rod extension — brackets should extend far enough past the window frame that curtains, when open, clear the glass completely (typically 6 to 12 inches on each side)
- Centre support — rods over 180 cm wide need a centre bracket to prevent sagging
- Wall anchors — curtain rod brackets hit drywall between studs in many positions; appropriate drywall anchors are essential for heavier drapery
Vertical blinds
Used on sliding doors and larger windows. The headrail is mounted above the door or window opening (outside mount) with one bracket at each end. Installation is quick but the headrail must be precisely level — a slight tilt causes the vertical slats to hang unevenly and not align properly when closed.
Calgary-specific installation notes
Concrete window headers: Older Calgary homes — particularly those built between 1950 and 1975 — often have poured concrete lintels above window openings. Drilling into concrete requires a hammer drill with masonry bits; standard drywall bits will not penetrate. We bring hammer drill capability to every job. Concrete installations add 10 to 15 minutes per window versus drywall.
Vinyl windows with plastic frames: Many Calgary homes have vinyl window replacement units installed in the 2000s and 2010s. Inside-mount brackets on vinyl frames use small screws into the vinyl — the frame is strong enough for light-to-medium blinds but we confirm the frame construction before installing heavy blinds on vinyl mounts.
Window trim profiles: Older Calgary homes often have thick wood casing around windows. Outside mount rods and brackets need to clear the trim profile; we check that bracket arms are long enough to hold the rod away from the wall at the right distance for the curtain rings to slide freely.
