The Door Is Installed Level & Plumb, but it still doesn’t work!


Has this ever happened to you?

We Can Help!


You’ve tried to do everything right, taking your time to find level & plumb perfectly.  Even shimming properly at each hinge location, but no matter what you try – the door frame will not line up correctly with the slab.  (learn some shimming tricks here)

Let’s trouble shoot some of the possible causes below:

1.  The door slab is level, but the sill is not

This is one of the most common issues when you’re facing the problem the door being installed level & plumb, but it still doesn’t work.  Look at the picture below to get a better idea of what’s going on here.

A level sill is the foundation for a good door installation

As you can see, even if the door is level & plumb – if the sill isn’t, you will have a hard time getting your reveals to line up correctly.  (learn more about getting a level sill here)

2.  The door’s frame legs are not installed true with one another

Here is a picture of another trouble-spot that we’ve seen on job-sites.

Doors 101 - True

Note how the door legs don’t align with one another

It is possible to have a door slab level & plumb and one side of the door frame level & plumb. But if the other side of the door frame isn’t true with its partner – the door slab can appear warped because it will pop-out from the frame in one corner.  (you can learn more about what installing a door true means here)

3.  One of the door’s components was manufactured incorrectly

Even though it’s rare and door manufacturer’s try very hard to produce every unit correctly, it is possible for a part to be made incorrectly and find its way into the field.  Fortunately, you can check that your door was made correctly by measuring both frame legs to make sure they match and both head and sill to make sure you have a matching pair.  As for the spacing between the door and frame (usually called the reveal) it is recommended that there is at least 1/8” on both the Strike and Head sides of the door and 3/32″ on the hinge side of the door.  We’ve put together a diagram below to help explain this.

Proper reveals are required to maintain Energy STAR® ratings on exterior doors

4.  The door slab is warped

Again, this is rare for a new door. But it is possible for the door slab to warp before it has been installed.  If this has happened, the door will pop-out from the frame in one corner as mentioned above. It will also not match with its frame.  An easy way to test for this is to use a string pulled tight from the top of the bottom of the door corners. (as shown in the picture below) If the gap is larger than ⅜” from the string to the door, it is warped.

How Important is a Level Door Sill?


it’s not that big of a deal… is it?

Let’s Take a Look at Why a Level Door Sill is So Important.


It’s a Big Deal…

This is a question that most people don’t think about before beginning a door installation, but it might be the most important step to take. Installing a door with a level door sill is like building a house on a level foundation, you have to start right to end right.

picture-correct-door-sill-vs-an-incorrect-door-sill

As you can see in the picture above, if you don’t start with a level sill, it’s practically impossible to end up with a good result to your door installation. The sill is the door’s foundation, if it is out of level; the problems compound over the height of the door and become much more difficult to troubleshoot.

A Level Foundation is the Key Building Block to Any Structure.

Now that we know we need a level sill, it’s easy right?  Well in the real world, you’ll find most construction sites don’t offer a perfectly level sill area in the rough framing.  In fact, it’s very uncommon to find a perfect RO (rough opening) with a perfect sill. So what do you do?  You fix it!

Take the time

It’s important to use a straight edge level long enough to run the entire length of the door sill to make sure that the entire span is level and without dips or rises. A dip or a rise in the sill must be fixed before beginning the door installation.

One of the best methods we’ve come across to fix a dip or a rise in the door sill is to use strips of Ice and Water shield (found on most jobsites as a roofing underlayment) or asphalt shingles to build up the rough framing in order to create a level door sill.  Depending on the thickness you need, the strips are easy to cut and stay nicely in place where you need them during the door’s installation and afterwards.

Fix Any Problems Before Moving Forward with Installation!

By taking the time to complete this small step, you will find that many common door installation problems disappear when you start with a level sill!
