[@sgleiman]

How do you pre-hang the joists before adding the joist hangers?

[@dinotudisca3821]

We toe screw the joists to the ledger and then add the hangers. You can also add a cleat to the top of the joist and gravity hang the joist to the ledger

[@rodharris7114]

As an older guy, I am now seeing the results of years of doing this with no hearing protection. Folks, please please wear hearing protection and eye protection. The hearing damage is cumulative even as a part time do it yourselfer and I have lost count the number of times something has bounced or flew off and hit my glasses. Great video though ! Good practices

[@jimhardiman7735]

I wish someone told me that about condoms 4 years ago.

[@josephwhelan192]

Rod Harris is right. I am 45 and have a ringing in my ears. When I was in my 20’s and early 30’s I was too tough to wear earplugs. Now I’m paying for it. Wear them or you’ll wish you did.

[@dalesworld1308]

And I can imagine the tendonitis after a day of using that nail driver. He's using padded gloves but that repetitive vibration will destroy your nerves over time.

Ya I’m going deaf as well from framing houses for years on end only protection I ever wore were my safety sunglasses I was Forman/cut man ran a saw 8 hours a day most days, plus I was a Drag racer car was so loud it shook the ground

@@jimhardiman7735 right tool for the right job, bud.

[@lynsarver7899]

how did you hold the joists to the ledger before you put the hangers?

[@drdecks]

15ga finish nails

[@LtKregorov]

Tips for the one who to do that wifey! Go with structural screws for all the holes (inches and a half and the 2 and a half). Why? Because you can give her an impact driver that is light and doesn't kick in your hand and she will be able the do all the screws while you measure, cut and place. My wife got so good (from never doing any of this before) that half the project in she was almost waiting on me to bring the next joist. Hangers on both sides so it's 20 screws per joist. She did over 1000 in about 2 days. Screws are more expensive than nails indeed, but it is all worth it!

[@seanthomas1635]

How are the joists hanging before the hanger is installed?

[@jamieh4148]

They always skip over the hard part haha. I guess this was just about the hangers so it makes sense.

[@checkurhead_3472]

Joist tape. Duh

[@howtodoitdude1662]

How do you attach the joists to the ledger before installing the hangers?

[@bpdp379]

They look just friction fit?

[@MrHappy629]

I learn something new with each of your videos. Thank you from an older DYIer.

[@BERETTA9mmUSA]

Thank-you Sir! Doing some touchup on my deck, and I wanna make sure I’m looking at the correct things. 🤠👮🏻‍♂️🇺🇸👍👻😉. B9USA Sr.

[@webb-cast1030]

IMO joist hanger should have a hole in the bottom for the first nail/screw to make sure it's tight to the joist. That would also make distributing the hangers much more efficient. You could fill a bucket with hangers and tack them along the full length of the ledger. Then go back with the nail gun/screw gun and finish them off.

[@HiTheNameIsBj]

Wow, that's actually a really good idea.

[@Pseudify]

Interesting idea. However, if the joist does shrink, instead of pulling away from the hanger, now it would be held down by the hanger. Would that potentially make the deck surface uneven?

[@aaronjennings8385]

I can't overstate the importance of the correct fasteners. Nails, screws, bolts... ask if you aren't sure, it's more than important that things aren't nailed down or screwed up...

[@raycstout1695]

What are you using to temporally attach the joist to the ledger prior to the installation of the joist hangers? Good video! Thanks.

[@thronewalker9079]

tac nails in at grade both sides of joist.

[@bend4852]

Glue

[@EdurtreG]

Nice tight fit, but sticking out at the bottom, which is ugly and a nice hidingspot for W&W (water and wasps).

[@mathewsdita]

I am first time my own floating deck builder and I learned lots from your video. I live in the place where we don't get earthquakes though I bought #9 and #10 screws that you are referring to. Now I can install my joistes like pro. Thank you.

[@Dr-wheel-barrow-opperator]

You have taught me so much. I want you to know, I appreciate you and what you do for us!

[@jimkendall934]

What holds the floor joists in place while installing the hanger?

[@ronaldnordman2463]

I have the same question

[@twoputtray]

I have two thoughts. I believe that Simpson disallows the use of nails and screws in the same joist hanger. Am I wrong? Next, the #10 SD screw is difficult to thread into the hanger and Simpson said to use a #9. I'm trying to figure out how you got a #10 through the hanger hole. Nice job on the video.

[@andressosa898]

On to change all my hangers now that I saw your video before my inspector comes…🤣

[@tomb1734]

I don't understand how your joist are staying in place on the ledger for you to come back later and install hangers. I install as I go so they don't drop out of place. I've tried to angle nail before installing but the joist moves sometimes or the nail ends up in the way of the hanger.

[@dannyboycharter7698]

just for shits and giggles..... the end of pressure treated ledger joist needs to be treated with a fungicide.

[@wayneosaur]

How are the joists staying in place before you add the hangers? Are they toe nailed above? Magic?

[@gil1390]

Got the same question…

[@wayneosaur]

@@gil1390 Yeah its sort of a chicken and egg problem. I need the joists in place to set the hangers, but I need the hangers to place the joists.

[@spectrum10]

What is holding the joists up if you installed them before putting the joist hangers in?

[@snarecat3441]

Toenailed

[@checkurhead_3472]

Joist tape. Duh

[@robertesteva2299]

Thanks! Keep up the amazing vids. Thank you for sharing your knowledge.

[@chadbenedict3898]

Hanging the boards first is such a good idea! because, no two boards are the exact same diameter. Thanks for the info, it also helps to know the lingo when I walk into to lumber store. ;)

[@andyprairiedog]

That palm nailer...amazing! i need to get myself one. Using a hammer on the 3 inch nails gets pretty loud when hammering away with joists on each side of your head. Ear muffs also helped. One or 3 joists, no problem. Installing a deck sized project gets pretty tiring though.

[@jacked-666]

Simpson makes alot of different bracket, I know you're busy man but would like to see how all Simson brackets are used. Thx drdeck

[@cryptojihadi265]

Dear LORD, I think my buddies without any construction experience completely bombed out of their gourd wouldn't be dumb enough to NOT have the joist hanger right up against the bottom of the joist. I would be shocked if I came across that once, let alone as frequently as you see it.

[@chemicle]

Thank you. I stepped out on my deck (about 4 feet off ground) and it started to pull away at the house. I stepped back in quickly, and only one corner of the deck was like that. Looking underneath - NO JOIST HANGERS. This is the first video I came across in my search for confirmation that they are required. YEP. Mine have none. I find it odd even I knew they were required when the person who built mine had no idea what they were doing. NOW to see if I can buy these hangers and fix it. Thank you so much.

[@jerseyjim9092]

So how are the joists held to grade prior to installing the hangers? I don't see any toenails.

[@CuttingBoardRx]

Great video, short, sweet and to the point! Thank!

[@chrisgee3197]

Be sure to check the Simpson Strong Tie SD Connector size chart to get the correct screw size for each piece of hardware. I’m using both LUS and LUC (concealed flange hangers) on my deck, and while the LUS hangers use both 1-1/2” and 2-1/2” SD screws, the LUC are spec’d with only 1-1/2” screws.

[@kevinallen6197]

[@nobreighner]

Putting zinc against copper-treated wood in a humid environment will cause galvanic corrosion. Z-max (G-180) is just more zinc to sacrifice.

[@puite68]

never would have thought i would sit through a 9 minute video on how to install a joist hanger, yet here we are. bravo.

[@albertramos3808]

Hey Dr. Deck, I want to thank you for the GREAT! video very well explained I needed to hear the size of the nail and screws for the size of the hanger. Thank you again and please have a fantastic day!

[@erichood3169]

Its always hilarious how many people say "you need roofing shims for this"

[@aprilrosenblum]

Thanks so much for explaining how to affix joist hangers! Our condo doesn’t have a deck, but this helped us create a second level in our small indoor space. You are great at explaining how to use this.

[@robertbutler8004]

April and you had to watch this to know how to install joist hangers unreal. news flash it is not rocket science.

[@gralbr]

Very detailed, and correct information on how to install a joist hanger. But lumber shrinks, particularly pressure treated lumber, will shrink as it dries out. Even in an outdoor application. So after a year or two there will be a space (gap) between the bottom of the joist hanger and the bottom for the floor joist.

[@mos8541]

regarding the bottom of the hanger being tight to the beam/joist... theres a HOLE in the bottom (some i guess) for a reason... USE IT

[@tymr.t3645]

Thank you so much for the info Good explanation. Excellent video 😋

[@mojoman2001]

The joists were already hung when he started. How did he fasten them to begin with?

[@RWR71]

Really

[@BigJohnson1566]

Good intel, much appreciated.

[@pxckbl6883]

Great explanation and straight to the point! Helped me out a lot. Loved every bit of it!

[@GeorgeHamberhill]

Can the Strong-Drive #9 x 1-1/2-in mechanically galvanized Strong-Drive SD exterior wood screws be used in the joist hangers to ledger?

[@sambo5103]

I remember awhile back seeing this video using proper hanger screws. I'm reframing my old deck and did simple search to find this video. Thx for keeping us straight out here!

[@cjpenning]

Also, helps to squeeze the hangers before putting them on because they are usually stretched out.

[@PumkpinSpiceAvery]

What if my joists are at an angle? Do I need special hangers?

[@BADBRAD1959]

Ok you say use joist hangers nails on the face nailing and SD 2 1/2 screws into the diagonals yet Strong tie on their website say "Nails and Strong-Drive SD Connector screws may not be combined in a connection." I'm confused now is the face nailed considered one "connection" and the diagonals a different connection? Please explain

Hey Dr! What type of benches are you using on your chop saw ? Looks like a wide platform that can adjust to chop saw height. Thanks Man!

[@___asd159gh43]

Love this explanation. Do you have any new videos on reinforcement for spas?

[@febsat]

Excellent and thorough and very informative. Disappointed when you used the nail gun without safety glasses.

[@benisplayin]

So many times the process approved by one cities building authority is not by another. In California we supposedly have a UBC. Unitized building code. That translates to the same inspection procedures are used across the state. I have found this relates to something like reading biblical scriptures. Not everyone has the same interpretation. .

[@oldnstillworkin5709]

RIP Eddie. You are missed. So glad I saw a show in the 80’s

[@WhistleLad]

[@AaronBrand]

I thought the not equal sign meant not equal to the number; like, it’s actually 2.475 inches (not 2.5)!

[@wolf8857]

I’m glad to see that you guys put the Simpson ties after the lumber has already been installed. I’ve seen a lot of KZbin “contractors” install the hangers first before the floor joists and it drives me crazy because that not the correct way to use them.

[@richardrumplik7023]

Thanks I’m putting up a Simpson HGUS210-4 it’s for 4 , 2x10’s . I researched it special ordered it and now over a month later I can’t find my installers guide online for it 😡 I did find some other info stuff from them. But not what I had seen when I ordered it about the nailing on the Ledger flange. It has like 20 holes per side. I think that was to make sure you had enough area’s to miss other fasteners !

[@richbrede4088]

How were those joists held in place prior to the installation of the hanger?

[@phazelvosfreqdetector7580]

I need an adjustable hanger. I was using 100 year old hard pine joists (in other words, actual 2" width), and ended up needing to chisel a little off each side to fit in the hangars. I tried making my own but the inspector wouldn't go for it.

[@weedreaper3844]

[@Saileahgaz]

To the community: Any thoughts on the downsides to using concealed flange joist hangers for deck building?

[@boots7859]

FYI, anyone attaching their joist hangers with framing nails will likely get to redo it all once inspected. You want a Metal Connecting nailer, or one of those palm-nailer types like used here with joist nails. Would be nice if the Dr. would respond with the gun type and where he got it. All over the place in Australia and NZ.

[@MrFlasshhh]

[@Nmdixon-cu7vm]

You’re not supposed to use screws where there’s a load. Screws snap, nails bend. Bad information chief. 👎

[@RedWest2010]

not clear why you're using a 2.5" common going into a 1.5" ledger?

[@anthonyhitchings1051]

on older decks the 2x10 has shrunk off the hanger seat. So will new lumber if it is not kiln dried.

[@chrisreibold1634]

Adjusting the hangers to the size of the joists makes sense. What happens on the other end of the joist where it sits on the beam? Won't they be different heights?

[@ivor7407]

I call them hurricane hangers. Lol

[@josephruck1]

Good on calling out structural screws. I've seen tons of non rated screws in hangers, they fail

[@_.Dave._]

6:45,.. 2.5" nail no matter what the jurisdiction is trash for toenailing a joist hanger. Near nothing will be in your rim joist.

[@waynebinky]

Lots of info about hangers but the deck ledger board against the wall is questionable. Shouldn't these be going into the house rim with a staggered pattern for better strength?

[@LarryMcDonald08]

In the more part where video details are, it would be nice if you linked the material you discus in the videos so ppl can click it and it takes it to a store so they can confirm it’s the correct part, example the joists hangers or the screws.

[@Erin_R]

Hey, so I recently had a roof built over our deck.. the 6x2 s connected to the ledger do not have hangers around them.. just the 8 nails.. I’m in Texas.. is this safe , or did the builder just try and hurry through ?

[@douglasmichel6361]

@@Erin_R I would seek the advice of an engineer, without seeing it or knowing the size and weight on that beam, it’s hard to say. As a builders in the northeast we have snow loads to contend with so more likely we would be using hangers. You on the other hand may have greater uplift due to greater winds than we get. As I mentioned, if your worried about it which it sounds like you are, I’d consult a local structural PE.

Great instructional video. I guess I'm returning my 3" and 3-1/2" galvanized nails before my build. You obviously went joists flush to the top of the ledger board. Do you have a video showing that step as well as how you're temporarily securing that joist?

You use a nail gun and toenail it to the ledger.

Ahaha! Lesson learned! Especially on large distances, it is just impossible to eye ball it. You think you got it, but when you measure you are off by several inches. And then when you lay your boards with 3/16 gaps in between them, you quickly realize how wrong you were.
