    Trim is fantastic stuff. With just a few bundles and a power nailer, you can majorly crank up the dial on your home's design--in just a weekend or two.

    Trim is the kind of "low-level consciousness" change where your friends come over and say, "What have you done with this place...it looks incredible!"  Yet they have a hard time putting their finger on what you did exactly.

    Here's what it does:

    • Visually:  Think like an artist. In a purely aesthetic sense, trim is like "trimming" off the...MORE ragged edges.  Or it's like outlining certain areas of a picture.  It gives the room a nice, crisp, finished look.
    • Functionally:  Some parts of a house are not covered up; they are left open for certain reasons.  One prime example is flooring.  Flooring and walls do not meet.  The purpose is to let the two move independently of each other.  To cover that gap, baseboards are used.

    You'll be pleased to know that installing wood trim is definitely a do it yourself project.

    In this guide, we take a close look at the 4 most basic types you will use in your house:

    1. Window and Door Trim
    2. Chair Rail
    3. Crown Molding
    4. Baseboards

    Description

    Trim that frames the interior perimeter of doors and windows.

    Purpose

    • Hide ragged edges of drywall or plaster around doors and windows.
    • Sharpen the look of windows and doors; make them "pop out." White-painted door and window trim looks great against walls painted rich colors.
    • Cover exposed edges of door and window framing.

    Features

    • Always essential. All doors and windows need trim (often called casing or molding, too).
    • Door trim and window trim is usually interchangeable.
    • When tightly nailed...MORE to the framing and painted, trim almost looks like it's a part of the door or window--it's seamless.
    • Door trim is usually painted a semi-gloss or gloss so that fingerprints are more easily washed off.
    • Door and window trim can be bought as kits (as shown in the image), though not mandatory.
