September 28, 2022 – Pre-Hung Doors

September 28, 2022 /

Now that we know how to take a door out, it is time to talk about adding a new door. Sorry if you were hanging on for this after the previous entry, you have now had an open hole in your structure for several weeks! I fully intended to capture the installation of the new door but got busy and forgot.

To make matters worse, I have decided to modify the existing door rather than replace the entire structure. So, I won’t document installing a pre-hung door this time. But, let’s talk about them anyway.

Things to know before buying a new door:

  1. How wide is the existing door? Typical widths are 36”, 32” and 28”. This is how the new doors will be marked for sale.
  2. What is the swing of your door? When on the outside of the door, the side of the hinges will either be left or right. That is the swing.
  3. Know your framing, for depth. Old houses like mine have true, 2×4 framing, new houses are 2×6. By the time you add 1/2″ of drywall, 1/2″ of sheathing and siding, all of this makes a difference when buying a pre hung door.
  4. Do you have a standard door (or opening)? Measure the height of the door, it should be 80″ in height. If your door is less than that, it is possible to modify the door but cutting the frame and door down but is much more work.

This is the reason that I modified the door rather than the casing.

It’s not a great picture, but the reality is the frame of the front door is half an inch wider than the current frame in the back door. The main house is framed with true dimensional lumber where as the back of the house is framed with modern lumber. Instead of 4″ thick, it is actually 3 1/2″ thick. If you have this situation, you are going to either have to cut down a door built for 2×6 walls, add onto a frame that is framed for 2×4 walls or order a custom door.

The truth is there are no good options. I made what I thought was the easiest and quickest method by trimming the door and moving the hinges. Guess what, it worked. It takes some fussiness and careful measuring but it can be done.

The nice thing about a new door is that all of the weather stripping is new. Everything should operate smoothly and easily like the handles and latches. Today, you don’t even have to mortise the lockset in many cases. This is secretly one of my least favorite things to do. If it is a used door, take the time to fix the weather stripping, paint when everything is off, make it install ready.

The next thing to having the right fitting door is to make sure that when installed it is plumb and level. The door will never operate properly if it is not. Do everything possible so that the door can be installed plumb and level including modifying the siding, drywall or structure. I can’t express the frustration you will have over the life of the door if you do not.

End Your Programming Routine: Since I cannot show the installation of the door, I will leave it at that. We got lucky in that I was able to modify both doors to make them work. It very easily could have not worked out because I wasn’t paying attention to all of the variables when my wife ordered the door. Trust me, I have made all of the mistakes before, including ordering a door that was too small for the framing, installing crooked doors that don’t function, having to add onto the structure, removing sheathing., etc.

September 7, 2022 – Removing a Pre-Hung Door Properly

September 7, 2022 /

My wife has been hounding me to get new doors for years. I like the look of the front door, but it has never operated the way it should. I have messed around with the lock sets and the screws holding the door in place but it is no use. It is imperative that doors are installed plumb and level for them to operate to expectations. I finally gave in and when I take a level to the exiting door, it is way out of whack. Now it the time to finally get a door that works properly.

Generally speaking, a pre-hung door is simpler to handle than just a door blank. It should be cutting the entire unit out and replacing the entire unit. Getting the entire unit plumb and level should be easier as well because the door should operate within the frame correctly.

Of course, you can always get a door out by destroying the frame. And if your door works properly, you could just replace the door and not the opening. In this case, I am going to put the front door in the back because my wife want’s a little more privacy than the current back door offers. And since it is easier to install as a unit, I am going to talk about the way to get the door out without destroying everything.

Step 1, Cut all caulk and paint lines around the trim, inside and outside the door using a utility knife. Note: in a pre-hung door, the exterior trim is typically part of the unit. Make sure it is all the way free before prying on anything.

Step 2, Carefully remove the interior trim so that it can be reinstalled.

Step 3, Locate the fastening mechanism of the door frame to the structure. Some use screws through the hinges while others are face nailed through the frame itself. If screwed, remove them. Also, consider not just the hinge side but also the strike side. Long screws are often used to secure deadbolts. If the frame is nailed, it is best to cut the nails with a reciprocating saw.

One other tip, if you can see shims in between the door frame and the structure (like the picture above, upper left corner) it is a good bet that there is a nail or screw in that spot. Shims are uses to get a solid backing to nail/screw through so that the frame stays square.

Step 4, If the frame is free on all four sides, then carefully rock the the entire assembly out of the rough opening. I find this easier to do when the door has been removed from the frame because it is a lot lighter

If all goes well, you should have a door and frame that you can use somewhere else or even donate. As an FYI, most contractors do not take a lot of respect or care for re-use. So, if you hire someone to do this job, don’t expect that you will get a re-useable result unless you specifically ask for it. Also, expect that it will cost more because being delicate takes time. I missed my chance at salvaging fence boards because they just cut the panels and threw them away before I could talk about it.

End Your Programming Routine: Sometimes things are easier said than done. For instance, it looks like there was caulk/adhesive added behind the door frame but it somehow missed the installation and therefore the door wasn’t stuck to the structure. What I would have done in that case is sacrifice the outside trim to try and keep the rest of the door frame together. Overall, this took me about two hours. I will talk about installation coming up in the future.
