Exterior Threshold Replacement

We had dry rot under our door that leads to the deck. I replaced the old threshold and rotted material with a new subfloor patch (pressure treated ply) and new exterior threshold. This video shows each step I took. I'm just a homeowner who loves to do stuff myself. My real job is being an elementary school teacher!

Best flashing job I’ve ever seen. No moisture will ever get pass your flashing.

[@TrixedOut]

Thank you so much for your comment! I agree I don't expect to have any more moisture problems!

[@TrixedOut]

Glad it can help!

[@markfrye9178]

I hope to see more of your videos! That drawing of. the flashing really helped me in fixing my leaky threshold.

[@davey820051]

Good job. I was glad to see you turned up the inside edge of the self-stick flashing to form a back dam. I've done many repairs like this over the years (I'm a semi-retired constractor) and I like the way you went about this .

[@TrixedOut]

Thank you! That means a lot coming from a contractor!

[@handyforhire3032]

20 years in the handyman biz. We work very much alike. You may have done it off camera but one last detail was to caulk over the ends left and right. I also might have treated the jamb bottoms with and epoxy sealer when you had access but overall I'd say that was outstanding work. I too am aging and finding things increasingly exhausting. Be well!

[@TrixedOut]

Thank you! That’s high praise coming from a professional! I did caulk the ends. I slathered it in there!

[@rickcimino743]

Nicely done. I have one (strong)suggestion: put a piece of 5/4 PVC (Azec or whatever they sell near you) or a piece of your decking under the outboard side of the aluminum threshold for support of that edge. From the underside of the aluminum down to the deck. Otherwise people will step on it an bend it. Another observation (for anyone watching) if you build a deck under an existing door, drop the deck at least 5".

[@evictioncarpentry2628]

I agree on adding support to the front. They bend really easy especially if you had to add an extension for a wider door jamb.

[@TrixedOut]

Great advice! I never thought of that. I'll do that. The deck was built when we bought the house. Nevertheless, I didn't know about the 5" rule so I may have built it the same way. Thanks for the comment!

[@TrixedOut]

Good to know! I'll fix it.

[@scottsatterthwaite4073]

At least 5"? If you are going to leave a step (for ice/snow shed) it must be between 4" and 7".

[@johnurban7333]

I agree.

[@bking0220]

[@mikekoss1i]

I'm so glad I found your video because after playing with my hinges tweaking this tweaking that I finally realized my door was rubbing so hard on the threshold that no amount of adjustment that I could do without altering and moving my latches and raising the door when it fixed it. I love the thoroughness of your video as well especially seeing you had some rot going on I never thought of that being an issue and I've never replaced one so now I have a lot more knowledge about getting into this thanks a lot Nice work man looks great

[@TrixedOut]

What a wonderful comment! Thank you so much! I'm so happy I could help you!

[@jeremyreimer942]

Prime example of WHY you DO NOT build a deck flush with the floor.

[@TrixedOut]

No doubt!

[@johnurban7333]

Exactly. The guy that built my deck did that and I got moisture in the corner of my mudroom and ended up with a nest of carpenter ants.

Thanks for the video! Trying to get the nerve to tackle my back door. It is unfortunately directly on top of concrete slab. I suppose I will need to use masonry anchors!

[@TrixedOut]

I bet if you do a search on KZbin, you will find exactly what you need to know. You can learn how to conduct brain surgery on KZbin! Hahahah. I just tried, "threshold replacement on cement floor," and a bunch of videos popped up. Good luck and thanks for the comment!

[@dolfinwriter5389]

Another suggestion--I can see you're in California so maybe you don't see much cold weather where you are, but I would caulk all gaps from below and then use Styrofoam board insulation to block off the rim joist areas in the basement, and then seal those with gap filler foam. This will increase the tightness of your new threshold and effectiveness of your heat and AC, AND help keep out unwanted pests. I lived east of San Diego for 27 years, and we had a huge problem with earwigs certain time of the year. I was constantly working to close up and tighten our weather sealing to keep the little B's out!

[@TrixedOut]

Hi! Thank you so much for the advice! I will definitely do that! That may explain all the stink bugs getting in! I actually live in Iowa. I used to live in Cal but moved here about 5.5 years ago to be near aging parents.

Hi! If you have the right tools and good instructions, you can do just about anything!

[@rays9033]

The new subfloor looks really thin. Most likely that threshold flexes when walked-on? And is that subfloor piece Pressure Treated wood to slow the future rot?

[@TrixedOut]

Hi! Thanks for the comment. Yes, the plywood is a scrap from a sheet of severe weather (pressure treated) ply I got at Lowe's. The thickness is the same as the rest of the subfloor, plus I added those support pieces to make sure all edges were supported. There are also those two floor joists that run perpendicular to the long edges so all that makes it very sturdy. I went and checked to see if I could make the floor flex and it doesn't so I think I'm good. I really appreciate these comments. I'm just a homeowner who likes to do stuff myself. By day I'm an elementary school teacher!

[@coryslaney]

Great work! Where do you purchase replacement thresholds?

[@TrixedOut]

Thank you! There’s a link in the description that will send you to where I got mine on Amazon.

[@markfrye9178]

just curious. Do you think that rot went any further inside than just the threshold?

[@TrixedOut]

No, I checked from above and below in my basement. It was just below the threshold and a bit under each door frame. If you look at the basement scene, you can see that the hole I created goes under each door frame about an inch and the rot stops there. I used a screwdriver to poke around down there to make sure the surrounding sub-floor was solid. All that was filled in with the new sub-floor. After adding the first layer of flashing, I slathered the flexible flashing cement under the door frames below the new sub-floor (part of the lost footage) and then screwed down the sub-floor. Then I added the second later of flashing. It's about here when the video picks it back up.

[@djmitch8495]

Is that code? In NY Its 2-4 inches drop to the outdoor deck.

[@TrixedOut]

No idea! The deck was there when we bought the house.

[@johngriffin824]

how much time did it take, please answer this question

[@TrixedOut]

Several hours for sure. I work at a leisurely pace. I didn’t really pay attention to time.

[@vapeurdepisse]

I don't understand why the red and yellow (top 2 layers) of flashing are not just one piece?

[@TrixedOut]

The flashing isn’t wide enough so I overlapped it like roof shingles.

[@bricks312100]

What about the gap under the storm door?

[@TrixedOut]

Hi! I swapped out the weather seal down there as well. I just didn't film it.

[@zeke112964]

how did you attach it to the door frame?

[@TrixedOut]

The new threshold is just wedged between the door frames. I cut the new threshold so it was the same length as the old one, which means it would have to be smacked in there with a hammer, as you see in the video. There is also flexible flashing cement under each door frame, just to be on the safe side. Once the threshold is screwed down, the door frame is locked in.

[@johngeraghty4349]

Thanks for your thoughts

[@diydan30]

Have you noticed any water getting past your flashing? You did a phenomenal job but I think two small improvements could be made. 1) It looks like you created a void with the way you overlapped the flashing where water can pool 2) it looks like you ran a continuous bead of rubberized caulk under the sill which will prevent water from draining out which may exacerbate point 1. However, I doubt either will cause an issue as you have a storm door, and that should prevent water from directly hitting the entry door and running down to the sill joint, where it might be able to get behind it. Honestly, I am surprised the sill rotted in the first place with the storm door in place. I learned a lot, thanks for posting.

[@TrixedOut]

Thank you for such a great comment. No, I have not noticed any leaks at all. This weekend I'll double check. I can see what is happening underneath the floor by going into my basement.

[@TrixedOut]

We have like 2' of snow on our deck. As soon as it melts, I'll go see how things look. I don't see any evidence of leaks now. Seems like, if it is going to leak in, this is the time since the snow is just piled up! I'll keep you posted.

[@diydan30]

@@TrixedOut I hope you dont find anything. I think the only way it could get wetter is if there is driving rain hitting the door. If it passed that test, you are good.

[@TrixedOut]

The snow is melting fast around here and no evidence of leaks!! Yahoo! Thanks for all the tips!

I know why there is no audio : ) I have to replace my threshold for the same reason but can not find the wide thresholds to replace mine. They are all 5 1/2 " wide, mine is about 8 inches and I just finished installing a vinyl plank floor so now it's going to be 3 1/2" short. Ugh....

[@TrixedOut]

Hahaha I assume you are referring to all the grunting. That is a super wide threshold you got there. If I had that problem, I'd either add a wider transition strip or extend the hardwood floor out the doorway a bit. Thanks for the comment!

[@skygh]

Pemko probably has the threshold you need

[@vapeurdepisse]

Yes I got a 9.5 incher... old house

[@scottsatterthwaite4073]

Look for a threshold extension. It's an extruded aluminum piece that locks into the outside edge.

[@samueldavis5895]

Sill extender should do the trick

[@emcee7670]

Would have preferred voice over to the music, but a great video nonetheless.

[@TrixedOut]

Thank you for taking the time to comment!

[@martinrobbins4945]

What is the cost for this replacement?

[@TrixedOut]

Hi! I only needed to buy the threshold and flashing because I had all the other stuff laying around. If you click on the links in the description you can see the current costs.

[@martinrobbins4945]

I may have to do one because the adjustment track screws are stripped out and when they step on it it lowers and breaks the seal under the door for air to come in. I wanted to try and fix the adjustment track but if I can’t I am going to have to do a complete tear out and install. Was just looking to see what is fair to charge them for the complete job. Not sure of course the amount of work that’s gonna need to be done of course without pulling the existing one. I doubt it would be as bad as the one you did but like I said I haven’t pulled it yet

[@Mario5301971]

Any way I could pay you to come do mine?

[@TrixedOut]

Ha! Thanks for the vote of confidence!

[@vapeurdepisse]

Only mistake is you should have run the glue perpendicular (several strips) to the threshold so water doesn't get trapped

[@TrixedOut]

Thanks for the tip! Hopefully everyone sees it. I did put a lot cement under and along the front of the subfloor. The subfloor (and therefore the threshold) slopes to the outside just a bit. I was figuring water wouldn’t travel uphill. What do you think?

[@vapeurdepisse]

@@TrixedOut it's good to have several layers of safety. If your assembly fails somewhere over time, at least the water has a way out.

[@scottsatterthwaite4073]

The idea is to keep water from getting in. The inside of a home is not usually a wet space. I install doors and the manufacturer always wants two or three parallel beads of silicone all the way across the opening.
