Can I install window security bars myself?

Yes. SWB bars are designed for DIY installation. The process requires a drill, level, and tape measure. Average install time is 15–30 minutes per window. SWB includes all mounting hardware, a full instruction sheet, and access to installation support. 94% of SWB customers self-install with no assistance.

How much does professional window bar installation cost?

Professional installation by a locksmith or handyman typically adds $75–150 per window on top of the bar cost. For a 4-window project, professional labor adds $300–600. Given that the installation process requires only basic drilling, professional installation provides no security advantage over careful DIY.

What tools do I need to install window bars myself?

A drill (cordless is fine), 3/16" drill bit, level, tape measure, and pencil. All brackets, anchors, and mounting screws are included with SWB bars. No specialized tools required.

How long does window bar DIY installation take?

First window: 20–30 minutes (including unpacking and reading instructions). Each subsequent window: 15–20 minutes. A typical home with 6 windows can be fully secured in 2–3 hours.

When is professional installation actually worth it?

Consider professional installation for: (1) masonry walls requiring hammer drill and concrete anchors, (2) custom fabricated bars without pre-drilled brackets, (3) very high installation points requiring scaffolding, or (4) commercial applications with code inspection requirements. Standard residential installation on wood or drywall frames does not require professional help.

What if I drill into the wrong spot?

This is the most common DIY concern. SWB brackets have slotted holes for 1/4" of adjustment — if a pilot hole is slightly off, you can correct with the slot. If a hole is drilled in the wrong location, fill with wood filler (under $5) and re-drill. This has no security impact.

Are professionally installed bars more secure than DIY?

No, security outcome is equivalent. The bar's 11-gauge steel and anchor system determine security — not who drills the holes. The only scenario where a professional produces a meaningfully different result is masonry anchor installation, which requires specific tools and torque specification.

What anchors should I use for different wall types?

Wood stud or window frame: included 3/8" wood screws. Drywall with no stud access: toggle bolt anchors (sold separately). Masonry or concrete block: 3/8" concrete expansion anchors and hammer drill. SWB bars include wood and drywall hardware; masonry hardware is available as an add-on.
