Installing a Door Threshold (with Concrete Underneath) 

Your video is awesome thanks for your time Dion

Hey everyone, I appreciate all the feedback and critique. So contrary to what many believe, the jamb doesn't necessarily need replaced. It can be filled. I filled it because it saved the customer about $250+ on a new door and labor. I'll see if I can find a video of it that I made. To fix the jamb, I used a piece of wood of similar size and Bondo All Purpose Putty (I recommend using googles, mask and gloves). I used a finish nailer to secure it, followed by the all purpose putty which was later carefully sanded. @Fred R. I believed I used a M-D 36-in x 5.625-in Aluminum/Wood Door Threshold (Install with Screws) Item #7295 Model #78600 Hopefully this helps.

If those are carpenter ants, you want to get an exterminator out there. They can do massive damage.

I may be wrong here, but didn't you install those press in nuts on the wrong side of the strip of wood? Shouldn't they have been installed from underneath? Seems to me that by tightening down on the screws would pull them out.

What's the appropriate alternative in a case where one can't drill down to secure? My back door threshold disintegrated after 35yrs of sitting on a raised concrete block from garage to back deck. Step up about 4" to concrete/threshold, then just enough space for threshold piece, then the concrete goes back down. This makes drilling into this narrow section risky. Don't want a crack problem.

You should filled that cavity with some cement. Also, replace your rotted out brick molding. Oh, and caulk around all edges.

So, the first question you and the owner should ask is, why are there ants?

What is the name of the connecters you hammered into the concrete?

I'd fill that space with epoxy concrete compound.

at 3m55sec what is it that you are holding and screwing into the threshold what is that piece of wood/called?

Good information Thanks If you could what is the brand on the sill you installed? I have the same exact gap on my lower level entry. Appreciate any info

Why not replace the whole door the wood looks kinda rotted

Two tapcons would work

better to replace all that rotten trim on both sides.

Even my white collar ass knows you should’ve put 3 beads of sealant down.

Bro, did you just use an angle grinder with a masonry blade to cut metal?, on your knee with out the handle? Wtf. You should delete this video before some kills or hurts someone following you directions.

Should Of replace the whole door frame it’s dry rot not just replace the threshold lol Please skip this video you can tell this guy does not know what he’s doing

Hack job. Don’t copy this guy… like other commenter stated, should have fixed the rot. If customer doesn’t have the money or didn’t want to, fine… but in the video, he says there’s bad concrete under threshold and that’s why it’s not fitting well. No job should be done without fixing the issue you’re dealing with first. Hack job of a guy.

It's not about saving the customer money it is about doing the job right.
