How to Adjust French Doors: Looking at common problems

Let’s run through the process of fixing French doors that stick, step-by-step. Hopefully, with this guide, you’ll feel confident identifying the causes of some common problems with French doors and know how to fix them. In the long run, learning some basic door maintenance will save you time and stress!

Why are my French doors sticking?

One of the most common reasons for french doors sticking is that the latch and the door are not properly aligned. This can happen for a number of reasons and isn’t necessarily because they were fitted incorrectly.

Many new build homes need to ‘settle’. House settling is essentially when your home gradually sinks further into the ground due to a shift in the soil beneath the foundation. It sounds scary, but it’s very common and is not a big deal in most cases. It can lead to foundational damage in severe cases so it might be worth checking for tell-tale signs like cracking in your walls if you think this could be the culprit behind your doors sticking.

Another common reason is simple wear and tear on the hinges. This is especially true with external doors that are exposed to the elements. All door materials, whether it’s uPVC, metal or wood are impacted by the environment. Changing temperatures, such as sudden drops or heatwaves can cause the material to expand and warp. This isn’t always obvious enough you can see it but you’ll be able to tell when your doors start to stick.

Luckily, it’s not that difficult to adjust hinges without calling in a professional. It also doesn’t take that long so with the right know-how, you can have your doors fixed by the end of the day.

Adjusting French Doors Hinges

  1. Remove the hinges from your doors. There will be two of these per side.  Use your screwdriver to remove them. Be sure that you have a friend to hand, as these doors can be heavy, and you don’t want them to fall over.
  2. Using the original screws, attach the adjustable hinges to the doors.
  3. Now comes the tricky part. Get your helper to hold the door level with the frame, and screw it into place.  To keep everything entirely level, you might need to place shims at the bottom of the door.  A few pieces of cardboard should do the job nicely.

Once your French Door hinges are in place…

Now that your door is actually in place, you’ll be able to make some actual adjustments.  A set of adjustable hinges will allow for several different sorts of modifications.

Why Don’t My French Doors Close Properly?

If your doors aren’t quite parallel with the surrounding frame, they’ll start to drag.  This is a leading cause of French doors that hit each other. This misalignment will develop over time, thanks to gravity and the warping of the frame. You’ll need to adjust the corner bearings, which are to be found on the bottom hinge.  Remove the cover and turn the adjusting screw to lift and lower the leaf.

The gaps might well have appeared to the sides of your door, and in the middle, which will compromise thermal insulation. Measure the gaps carefully and adjust the bearings accordingly, making small adjustments to the top and bottom alternately, to keep the door parallel to the frame.

When you’re making these adjustments, measure carefully and often.  It might only take half a turn of your Allen key to get the job done.  Once you’re done, give the door a few test swings to ensure that they’re working as they should.

How often do I need to adjust French Doors?

It’s worth checking the alignment of your French doors every so often. Every six months should do it. You won’t necessarily need to adjust them every six months but it’s important to check. Regularly checking means you can check small misalignments from wear and tear before they become a big problem.

The good thing is practice makes perfect. Once you’ve made these adjustments for the first time, regularly repeating the feat will be easy. More importantly, it’ll save you a great deal of hassle in the long-term!
