When installing new flooring, it’s a frequent query to wonder whether you should extend it under doors or not. This question isn’t merely aesthetic; it impacts the longevity and functionality of your flooring. Let’s delve into this conundrum, looking at where to stop flooring under doors for the best results.
There’s no one-size-fits-all answer to this question, as various factors influence the decision. These include the type of flooring, the door, and your personal preference. However, knowing the pros and cons of each approach can help guide your decision.

Leaving a Gap Under Doors
The most traditional approach is to leave a small gap, usually around 3/8″, under interior doors. This is primarily to accommodate for the thickness of the door itself. However, it also allows for seasonal expansion and contraction of the flooring.
The primary advantage of this approach is that it prevents the flooring from binding against the door when it swells, which could otherwise cause damage to the flooring or the door. It also allows for easier cleaning since dirt and debris can fall through the gap.
Gapping for Wooden Floors
For hardwood or engineered wood floors, ensure the gap is a minimum of 3/16″ to allow for expansion. This is because these materials are more susceptible to changes in humidity, which can cause them to swell and shrink.
It’s also wise to leave an expansion gap along the walls, typically 1/4″ to 1/2″, to prevent the flooring from buckling due to expansion.

Gapping for Other Flooring Types
For other flooring types like tile or vinyl, 1/8″ to 1/4″ gaps should generally suffice. However, always check the manufacturer’s recommendations, as the specific needs can vary depending on the product.
Remember, the gap should be consistent throughout. It’s a good idea to use door gap fillers or transitional pieces to maintain a uniform appearance and make the transition between rooms smoother.
Stopping the Flooring at the Door Jamb
Some people prefer to stop the flooring at the door jamb, running it up the side of the door frame. This can create a seamless look, but it’s not always practical and comes with its own set of potential issues.

Primarily, this method doesn’t account for the thickness of the door. If your door isn’t perfectly level, it could drag on the floor and cause damage. It may also not allow for seasonal expansion of the flooring, increasing the risk of buckling or warping.
Consider Issues with Door Clearance
Another concern is door clearance. If you stop the flooring at the jamb, you may end up with a small step down where the flooring ends, which could be hazardous, especially for people with mobility issues or young children.
Impact on Aesthetics
While stopping the flooring at the jamb can create a sleek, continuous look, it can also make your room feel smaller, as the eye will travel down the floor instead of across it. It also means you’ll need extra transition pieces at each door to maintain a uniform look.
In the end, the best approach depends on your specific situation and personal preference. However, leaving a small gap under doors is generally recommended, as it allows for the natural expansion and contraction of most flooring types and helps prevent damage to both the flooring and the door.

As always, it’s a good idea to consult with a professional or the flooring manufacturer if you’re unsure about the best way to install your flooring. They can provide tailored advice based on the specific conditions in your home. Happy flooring!
