How to fit carpet door bars

Door threshold strips have many benefits. For example, they help to secure carpet into place. They reduce lumps and bumps and improve safety. They enhance the final look of your new flooring, creating a seamless transition from one room to the next. And the best bit? Fitting them is a really quick and easy DIY job.

Here our experts have created a beginner’s guide to help you get started. Even if you’ve never installed a door bar before, simply follow the steps below and you’ll have it done in no time.

5 steps to fit door bars like a professional

1. Choose the correct door bar

There are several types of door bar to choose from and the right one for you will depend on your flooring styles. Single-edged bars have grips on just one side and are typically used to join carpet to vinyl or lino. Double-edge bars have grips on both sides and are used to connect carpet-to-carpet, whilst Z-section bars are used to create a safe transition from carpet to tiles, wood or laminate.

So, be sure to give it some thought and purchase the correct threshold strip for your requirements.

2. Prepare the door frame

Good preparation is always the key to a successful DIY job.

Before you start, unhinge the door from its frame and move it completely out of the way. This will give you more much space and make it significantly easier for you to fit the door bar accurately. It’s also a good idea to vacuum the subfloor and cut away any loose carpet frays using scissors.

3. Cut the carpet threshold bar to size

Here at Carpet Underlay Shop, all of our door bars are sold in 0.9 metre and 2.7 metre lengths. These are standard sizes for internal UK doorways. And so, in most cases, there’s no need for it to be cut. But if you have a particularly narrow doorway, the length may need to be adjusted slightly before installation.

There are two ways to do this. The easiest is to place the carpet door bar against the frame at ground level and mark the required length with a pencil. Alternatively, you could measure the width of the doorframe using a tape measure and transfer this measurement across to the door bar.

Then, place the bar onto a workbench and cut it – from the underside – using a hack saw.

4. Drill pilot holes

The next step is to drill pilot holes in the subfloor.

Place the carpet threshold bar in the correct position. Ideally, it should be central across the threshold, so that it can’t be seen on either side of the door when closed. Holding the bar securely in one hand, mark the screw openings with a pencil. Remove the bar and drill a hole at each marked position. 

Of course, before starting to drill, double-check for any hidden cables or pipes. And bear in mind, if you have a concrete subfloor, you will likely need a power drill and masonry bit to do the job.

5. Secure the door bar in place

Last but not least, place the door threshold strip back onto the floor and line up the screw holes with your pilot holes. Use a power drill to fix the screws in place. To prevent both unwanted movement and trip hazards, ensure each screw is as secure and straight as possible. And for best results, we recommend using a knee kicker to stretch the carpet towards the threshold.
