You know that your home is much more than the sum of its parts…but when it comes to design and planning, thinking through those parts is useful. To zero in on just one component: Fascia trim is an important part of locking in a unified look and feel and protecting your home’s exterior — and even your outdoor living space.

What Is Fascia Trim?

There are several related terms that you may hear used interchangeably, or sometimes together, when discussing both:

  • Your home’s exterior
  • Your deck

Let’s quickly take a look at each.

Home Exterior Terms

Fascia (often referred to as “fascia trim”) on a home is one part of the outside of the house. To understand fascia, you must understand a few additional terms.

Fascia trim and home exterior definitions

Exterior Cladding

On a home, exterior cladding refers to a type of siding that covers your home’s exterior walls. Cladding and other types of siding are important in protecting your home from the elements — but they are not the only protective treatments your home will need. Your home will also feature:


On a home, trim refers to the material used to encase, or surround, windows, doors, and other elements.


On a home, moulding is a type of decorative trim used to cover transitions between different surfaces, such as at the junction of a porch wall and ceiling (known as crown moulding).


On a home, soffit is the angled covering (wood board, PVC, or other material) that connects a home’s façade to the fascia or other structure.


On a home, fascia is the board that covers the edge, or face, of an overhang, like the eaves of a roof. It connects to the soffit and is sometimes called “transition trim.”

Within the context of a home’s exterior, fascia often gets referred to as “fascia trim” because it “trims” and encapsulates the edges of an overhanging structure.

Deck Terms

Discussions of “fascia trim” may also take place when the focus is not your home’s exterior, but rather, your deck. Why? Because fascia on a deck also covers the edges of a structure — in this case, the end cuts and/or rim joists of the deck.

(“Deck Fascia,” “Deck Fascia Board,” “Rim Joist Cover”)

On a deck, fascia refers to the boards used to cover the end cuts and/or rim joists, installed bordering  the deck surface (below, left).

Just like in home exterior’s applications, fascia “trims” (runs along the perimeter of) an overhanging edge (below, right).

Fascia on a Picture Framed Deck

Fascia boards can be part of a picture frame border on a deck, but not all decks with fascia include a picture frame border.

The difference has to do with the presence of a perimeter board, as shown below.

Finishing your deck with a picture frame border adds an attractive design element and keeps your space looking curated and contemporary.

The Takeaway

Fascia on a House

The boards that cover the edge, or face, of an overhang, like the eaves of a roof. Like other elements of your home’s exterior, fascia has both aesthetic and practical benefits.

Fascia on a Deck

The boards used to cover the end cuts and/or rim joists, installed horizontal to the ground, covering the rim board outside the exposed exterior framing. Fascia will “trim” the edge of the deck surface.

Now that you know what fascia is — and that it plays a role in both your home exterior and your deck — you’re ready to think through how you want each type of fascia to look and perform.

Fascia Both Ways: Exterior Design, From Home to Deck

Fascia on home and deck

Fascia acts not only as a protective layer at a structural transition point, but as an important polish piece that makes a big impact.

Think about homes that stand out in your neighborhood: Is their exterior fascia trim crisp, or is it unremarkable? Do their decks have visible end-cuts, or are they nicely covered by a fascia board?

Most likely, the homes you remember fondly are those marked by clean edges (trim, fascia, and soffit) and well-curated backyard builds.
