A Quick Guide To Hardwood Floor Moldings

As you might have guessed from the title, this article is all about the fascinating world of moldings! Okay, maybe it's not the most interesting topic in the world, but if you plan on installing new hardwood or laminate flooring than you will need to have at least a basic understanding of what moldings are and their different types and uses.

So, first things first, what is molding? In short, they are trim pieces that help you transition from one flooring type to another. For instance, hardwood flooring to carpet. They also help you transition to different levels, like at the base of a stair case. The key word to remember here is 'transition'. It's also important to try and match the moldings to your newly installed hardwood or laminate. With natural wood, the color can be slightly different between pieces as you're working with a natural product subject to some variations, but Hardwood Bargains supplies a wide variety to make this a non-issue in most cases.

Now, let's go over the types we carry and try to paint you get a clearer picture of their uses and designs.


First up is the T-mold. As you can see in the picture above, it's not hard to tell where this one get's its name. You want to use a T-Mold when you are transitioning from one hard surface to another hard surface of equal height. For a T-mold it's important that both surfaces are the same height, or the lower side will risk breaking when stepped one. This is why you shouldn't use a T-mold to transition to carpet.

A great example of when to use T-molding is when you are installing flooring across multiple rooms. In that example they are perfect for transitional doorways.

For installation, you need to leave a small gap between the two floors you plan to combine. The T-mold is then glued down where it meets the subfloor using construction grade adhesive. It is then recommended that you place a heavy object on the mold overnight to ensure a strong bond. Alternatively, nailing the molding down can be a good choice as well.


Thresholds are used when you are joining one surface to another of a different height. They have a rounded square edge that slopes off to ease the transition from one surface to the next without creating too much pressure on the molding.

This is what you would use if you wanted to bump a hardwood floor up to a carpeted room. They are also used when your flooring meets up with the tract of a sliding door.

Much like the other moldings, threshold moldings can be glued or nailed down at the edge of your hardwood or laminate flooring.


I bet you can't guess the intended use of stairnose molds right? Well if you guess stairs anyway, then you're correct. These are used whenever you want to use actual floorboards to cover your stairs.

You want to install the stairnose flush against the floorboards to create a seamless transition to the end of the step. They should be both glued down in addition to face nailing them.


Reducers are used when you are using a staple, nail, or glue down installation for your hardwood floors and want to ensure a smooth transition to a different flooring type such as vinyl or tile.

Like most other moldings, reducers can be glued down or nailed to the subfloor. Flush reducers should only be used on flooring that is glued or nailed to the subfloor as well, and never used for a floating installation as they will not allow for necessary expansion gap. For floating installation, you would want to look for an overlap reducer instead.

Quarter Round

Quarter Rounds are one of the most common types of molding used. They are used to cover the necessary expansion gap between a hard surface floor and a wall. Because they transition to a wall instead of another floor, sometimes these moldings will be color matched to the wall instead of the floor.

Quarter Round Moldings are the easiest to install. All you need to do is nail the moldings into the baseboard and you're all set.

I hope this gave you at least a basic understanding of the types of moldings that we carry and their various uses. Be sure to let us know in the comments if you have any questions or thoughts.
