Hello this is Dustin with Home Mender
and today we’re going to be replacing an exterior door jamb that was kicked in
this one’s pretty bad. It’s uh well it’s just awful. I’m going to show you how to
change it. Let’s get to it. We’re going to start by removing the old jamb taking
off the latches and the catches for the doorknob and deadbolt .Of course mine are
laying on the floor so I don’t need to remove them. We can pull the rest of the door
casing off just with a pry bar. Get any nails that are protruding hammered
back in. Pull off the weather stripping That one’s pretty old. We’re going to go
ahead and replace that, too. Go ahead and start by dismantling however your jamb is
secured. Sometimes it’s screwed. Sometimes it’s
nailed. This one’s been previously repaired so I have some face screws here we’re going
to pull off. Now what were going to do is we’re just going to kind of walk it out. We do not want to disturb the top jamb. You can pull any nails you’ve got left over.
If you can’t pull them use your trusty side cutters and just clip them. Do the same with the bottom. careful not to disturb your threshold. Once that’s off you can
see some screws or nails where the factory has nailed the threshold to that
side of the jamb, we’re going to clip those too so we can slip our new jamb
down inside. Now that we got our old jamb up we’re ready to install the jamb kit.
This jamb kit about $20. You get all three pieces. We’re only going to be doing
one. It comes with this little funky cut side that’s going to sit on your
threshold. Make sure you put yours in the right way. We’re going to put that side
down. Rest on top of the threshold and then we’re going to cut the top to fit.
Measure up from the bottom and you’re going to want it to run up past your top
header jamb. That’s 81 1/4 to the top jamb. We’re going to run ours
about a half inch further up. 81 and 3/4. Go ahead and pull off
your weather stripping. Square. You can see our old paint line right there.
That’s where we’re going to cut our new jamb to fit. Now you’re going to want to
cut this piece and this piece at different lengths. This top is going to
slide up beside our top jamb and this one is going to butt to it. Measure up.
81 looks tight. Let’s cut our inside lip to 81. Now of course, your measurements
may be different so definitely measure for yourself. Set
your saw blade depth so we don’t cut all the way through the jamb. That little
piece chips off and that’s ready to go in. slide the bottom in, pick up the
header and then push the top in. Fitting in nice . Now you can see how this
piece here butts underneath the jamb and the side slides up behind it. Let’s check
the swing of your door make sure it’s working.
Looking nice. Next, we’re going to shim the jamb. Now we know where the top and
the bottom are going to fall because they’re going to press up against your
threshold and press up against the top of your jamb so let’s go ahead and shim
that now . Get it nice and tight. After your top and bottom are shimmed. let’s close the door so we know what how far to shim the middle. Now that we got our jamb in
the right place, we’re ready to screw it off. I like to use deck screws. They’re
exterior and won’t rust and I find if you put the screws next to the weather
stripping slot, then you won’t see the screws. Make sure you screw where your
shims are, that way you won’t crack your jamb. Go ahead and cut or break your shims off. Next we’re going to install our interior door casing. You may want to insulate this if you have a big gap. I don’t have a big gap but we’re going to
insulate it anyway. Once you install the insulation, we’re
going to measure our door casing. From the ground. We’re going to measure to the top of the top casing. I’ve got 83. We’re going to use our trusty miter box
saw so we can get our 45 degree angle and since my truck has been raided
we’re going to use a hacksaw since I can’t find my trim saw. Once our casing is cut, we’re ready to fit it in. Secure it with finishing nails. Four or five nails should do it . Now
we’re ready to set our locks we’re going to shut the door and we’re going to mark
on our new jam where the deadbolt and the knob catch falls. Let’s go ahead
and fit our weather stripping in there so we can get our latch right. With the weather stripping tight now we can see where our latch falls. No daylight We’re
looking good and with your one inch paddle bit let’s go ahead and drill for
our latches. Put it right in the middle of your jamb. You will need to drill all
the way through for your deadbolt but you don’t have to drill all the way through
for your knob catch that’s up to you. Take your dead bolt catch and trace your
shape. Same thing with the knob catch. This one’s best to flip backwards to
avoid running into the nubby issue. Now, with your nice sharp chisel, we’re going to want to recess our catches. Only need to go in the thickness of the catch
which looks like about an eighth of an inch. Don’t bang too hard. Go ahead move all the way around the perimeter. Get creative on your little arches and then chisel out the middle. Now go ahead and install your deadbolt
catch. We’re going to make sure we use long screws in here so they contact the
stud. We don’t want just the security of the door jamb holding our deadbolt
closed. In case this happens again we want them to have to fight to get in. Now do the same thing with your knob catch. Let’s give it a test close. Looking nice,
deadbolt is engaging and we’re good to go. Alright, so that’s it we got our old
door jamb out we got our new door jamb in. Iit’s looking nice.
Everything’s shutting tight. Weather stripping is keeping all the daylight out. The locks are engaging and we are secure . We’ve got our new casing on. All
that’s left is to caulk and paint. I’m going to leave that up to you so for
