How To Add The Joists To Build A Deck

Alternate punny post title: Joist to the world. (I’ll pause while you golf clap)

Good news! My dad made it back from my grandma’s house in West Virginia so operation double-up the girders and bolt them to the posts was able to commence with him at my side. As I started to tell my dad “Okay, you’re going to hold the board in place in the air while I drill pilot holes…” he cut me off and suggested we just put both girder boards on the ground, nail them together and that way they’d both rest on the notched posts – no air-hold required. Smart. I knew there was a reason I picked him as a father.

Deck 37 Next Day Girder Down

So we clamped the girder boards together so what-would-become-the-top-edge was perfectly lined up (boards are never perfect, so even two boards marked 2 x 10 might be slightly different widths). Then we nailed them together.

Deck 38 Nailing Together

To refresh your memory about how this deck will come together, here’s this handy little graphic that hopefully makes it a bit more clear:

Posts Updated Graphic

Next we were able to rest the now double-thick girder on the notches and proceed with bolting them together. Our county requires us to use “two 1/2″ through bolts” – which meant I had to drill 1/2″ pilot holes through about 4.5″ inches of wood – which was a little bit of a challenge since my longest drill bit was barely that long.

Deck 39 Drilling Pilot Holes

But we got it done and were able to slide the bolts through with a bit of hammering, and then tightened the nuts on the other end.

Deck 40 Tightening Bolts

It was actually a remarkably simple process, and it probably took us about two hours to do the whole thing. Not necessarily a short time when you’re standing in 95-degree morning heat. But, I’d say it’s the first part of this process that has actually been faster than we anticipated.

Deck 41 Girders Both Attached

Oh, and here you can see how we joined the girders on the long side where it’s actually two sets of boards that butt up against each other on one post. It’s like a through bolt party up in here.

Deck 42 Post Where 2 Girders Meet

Since our morning was going so speedily, I even convinced my dad to help me go ahead and get the diagonal girder and posts measured, cut and set in place.

Deck 43 Diagonal Girder

So by about noon we were looking at having accomplished pretty much our entire goal for the day.

Deck 44 Done With Dad

Does that mean we get to stop? Of course not. Well, it did for my dad since he had other things to do at home. But after taking a breather (by which I mean working on something else inside with Sherry for a couple of hours) I returned to my slowly-getting-completed deck for my next step: laying weedblock and gravel.

A bunch of you guys have recommended taking some weed-preventative measures and I figured this was my last chance to have easy access to the entire space under the deck (since adding joists will mean lots of new obstacles). So I removed one existing obstacle – the diagonal girder that we hadn’t bolted in yet.

Deck 45 Girder Down Holes Filled

Next came the weedblock. Using some leftover from Clara’s rock box plus another $12 roll from Home Depot, I was able to cover the whole area without a problem. I have mixed feelings about weedblock (since my experience has been that some weeds just grow on top of it instead of under it) but I figured it’s better than nothing. And for about $15 (including the ground staples to hold it in place) it’s worth giving it a shot since it’s the recommended method in our area when it comes to dealing with the ground under a deck.

Deck 46 Weed Block Down

Next up was covering the area in gravel, since it’s harder for weeds to grow in a soil-less environment (and pests will like a weed-block-and-gravel-filled area a lot less than a damp-muddy-and-weedy spot to hide). My original plan had been to get a delivery of rocks from the same stoneyard where we bought the gravel for our DIY patio, but I forgot to place the order and then was too impatient to wait. So instead I picked up two car-loads of this bagged gravel from Home Depot (it was marked down from $3.38 to $2.50/bag, saving me about $35!).

Deck 47 Bags Of Rocks

It wasn’t necessarily easy hauling all of it from our driveway to the other side of the house where the deck is going in (again in near-100-degree heat) but by this point I had become pretty accustomed to being sweaty and gross (and the people at Home Depot were unfortunately accustomed to seeing me that way). So here’s the space slowly filling up with rocks…

Deck 48 Rocks One Third

Almost there…

Deck 49 Rocks Two Thirds

…and complete. It took me 40 bags total. I know I’ll need more once I put the stairs in, but for now I’m just going to cross that bridge when I come to it.

Deck 50 Rocks Three Thirds

It was about 7:30pm by the time I finished getting my rocks down, so I called it a day. Though I was almost excited enough to keep going because my next step would be joists… which meant it would finally start looking like a deck.

So the next day – despite being more sore than I’ve been in recent memory – I bucked up and got my joist on. Each of my joists would be about 7.5 feet long, so it meant trimming a smidge off of my 8 foot long 2 x 8″ boards.

 Deck 51 Marking Board Pivot

I mainly took this picture of me marking my cut because every time I did this my eyes kept catching the word “PIVOT” in the corner of my straight edge and this scene from Friends would replay in my brain.

Deck 52 Marking Board Ross

Anyways, once Ross was out of my head, I got to cutting with the circular saw – who’s like my new best buddy on this deck project.

Deck 53 Cutting Joist

Once cut, the joists actually just rest on top of the girders – so there’s no additional support needed to keep them up. But I did have to add some hangers on either side to give them some stability side-to-side. I had already installed all of the hangers on the siding side of the house, so it just meant adding them on the brick side.

Deck 54 Nailing Hanger To Ledger

And since these hangers were no longer about keeping the hangers up, it was actually more critical that I nail them in on the side (thanks to the handy angled-nail guides already in the hanger).

Deck 55 Nailing Hanger To Joist

This was by no means a swift process (each hanger required 10 nails) and it didn’t take me long to wonder if I should’ve bought a nail gun for this project. It wasn’t much longer after that that I was actually pretty certain I should’ve bought one. But alas, I just kept plugging along – thinking of how I would look like Hercules when all was said and done (spoiler alert: this did not happen, strangely enough).

Deck 57 Joists One Fourth

As I added each joist, I double-checked my level as I went. If they weren’t level (while accounting for a slight slope away from the house for drainage) there wasn’t a whole lot to be done since my girder was already set. But doing this did help me spot one board that was too warped to use (it curved up on one end). And had anything been too crazy un-level I could buy (or rent) a planer to scrape a bit off the top of the offending joist.

Deck 56 Checking Joist Level

Here’s Clara watching me build what she now called my “pretty pretty deck.” Not the adjective I would choose myself, but as long as she’s showing interest in the project – I’ll take it.

Deck 58 Clara Watching

Slowly but surely more joists joined their joist-y brethren and the space started looking more and more deck-ish.

Deck 59 Joists Two Fourths

When I got towards the end I did have to go ahead and bolt the diagonal girder in place, since the joists on the end would need to rest on it.

Deck 60 Joists Three Fourths

And finally, about four hours later – all of my joists were in.

Deck 61 Joists Four Fourths

I still have to add the rim boards along the exposed edge. It will be a bit complex because this is where I have to be precise about the angle I cut, so I didn’t have the mental juice left to tackle it after such a long day. And for now I just left the joists on the end extra long (once I’ve determined my angle, I’ll use the circular saw to cut them more precisely).

Deck 62 Joists Done

Not too shabby though, right?

Deck 63 Joists Done Aerial

Before the day was through, I couldn’t help but test out my new creation a bit. You know, to make sure it actually could hold some human weight.

Deck 64 John Testing

It did! So I broke out a little happy jig. Call it my “Happy Happy Joist Joist” dance if you will.

Deck 65 John Jigging On Joists

Once I get those rim boards in, my next step is deck boards. I can’t tell you how excited we are to finally be at this step. This project has taken much longer than we anticipated (for which I blame equal parts on ourselves, inspectors, heat, and the lack of an army of helpers to speed things along). Oh well, that’s DIY for ya. It’ll totally be worth it when we’re sitting out there sipping lemonade, right? What have you guys been up to this weekend? Any outdoor or indoor projects that are finally turning a corner and looking like they’re closer to done than undone?

Psst- Wanna catch up on all of the deck action? Here’s where we shared our vision for the space, then we removed the plantings and the old balcony, followed by selecting our materials and documenting our first day of building progress. Then we dug our post holes, and then learned that we failed our first inspection. We revised our plan and dug more holes (which got approved) and proceeded to set posts. Whew, all caught up.

    I seriously LOL’d at the “Friends” reference (and may or may not have yelled “Pivot!” a couple of times), and then about fell out of my chair laughing at John’s “Happy happy joist joist” dance. And then both times I tried to “like” the photo. Facebook has ruined me! ;) Looking good guys!

    Wow! It looks terrific. Don’t know if anyone has suggested this yet, but when you get toward the end (which is clearly coming really soon!) consider putting some chicken wire between the ground and the bottom end boards (sorry i’m not explaining this well) and attached to the inside of the end boards to keep rabbits, raccoons and other animals out. it’ll be easier to do this during construction than trying to retrofit it and the barrier will be hardly noticeable. i learned this one the hard way!

    You guys have inspired me, so 2 weeks ago we tore out our Pepto Bismal pink main floor bathroom with a toilet made for a midget. We have since been slowly putting it back together (2 small children along with it being our 1st major project have definitely slowed things down). But we now have walls so I can see the light at the end of the tunnel. I’ll send you a before and after photo when we’re done!

    Maybe I’m just under thinking this, but couldn’t you just snap a chalk line along the boards to be trimmed for the rim board?

    Fair notice, I’m no carpenter, so maybe not, but that’s what I would do.

      Are you talking about the angled rim board on the end that I’ve yet to add? If so, that’s probably what I’ll end up doing. I’m mainly just anxious about getting my angled cuts on the end correct.

    I think you might be afflicted with some type of weedophobia! :) I would say that the installation of weed block was overkill on a nearly enclosed deck that small. Hauling nearly a ton of rock in 100 degrees at a cost of $100 is OVERKILL+ Extreme. :) Weedblock and stone 3ft back from the end of deck would cover any reflected sunlight and stubborn weeds.
    I love the blog, and both of your attention to details. Thank you.

    Kudos John! I actually want to give you a massive pat-on-the-back for this project! It looks complex and time consuming, and much harder than what I imagined a deck project to look like (not that I spend much time imaging deck handiwork). It’s coming along beautifully and I bet Clara cannot wait to run right out of those patio doors and onto the gorgeous deck!

    Looking great guys! Can’t wait to see the finished product!

    I can never hear the word “pivot” without that scene popping into my head. I love when Ross tries to save his dignity by returning the couch — for store credit “in the amount of four dollars.”
