Electrical Box Installation Methods: How to Mount and When to Use Each Type

Choosing the right electrical box installation method is just as important as selecting the right box type or material. Whether you're mounting a metal junction box on a masonry wall, installing a PVC old work box into drywall, or setting up surface-mounted conduit in a garage, knowing the correct method ensures a safe, code-compliant, and durable electrical setup.

In this comprehensive guide from Brand Name Lighting, we’ll walk you through the different types of electrical box installation methods, including flush mount, surface mount, new work vs. old work boxes, and explain when and where to use each one. If you're shopping from an online electrical supply store, this guide will help you make an informed decision.

1. Flush Mount Installation

Flush mount installation is the most common method for installing electrical boxes in modern homes. The box is set inside the wall so that its front edge is flush with the finished wall surface (drywall, tile, or paneling). Once installed, only the device and wall plate are visible.

Best for:

• Interior walls

• Light switches

• Power outlets

• Wall-mounted fixtures

Shop flush mount boxes at Brand Name Lighting for a clean, professional look.

2. Surface Mount Installation

Surface-mounted electrical boxes are attached directly to the wall surface and are visible after installation. This is common in garages, workshops, basements, industrial facilities, and outdoor installations.

Best for:

• Garages, utility rooms

• Concrete, brick, or block walls

• Industrial buildings and commercial wiring

• Outdoor applications

Brand Name Lighting offers durable surface-mount metal boxes and weatherproof PVC options for a wide range of environments.

3. New Work Box Installation

New work electrical boxes are designed for use during new construction, major renovations, or anytime the wall framing is exposed.

Best for:

• New homes

• Major remodels before drywall is installed

4. Old Work Box Installation (Remodel Boxes)

Old work boxes, also known as remodel boxes, are designed to be installed in existing finished walls.

Best for:

• Adding switches or outlets to finished walls

• Minor renovations or upgrades
