As a carpenter and general all rounder great to watch projects like this and to see good trades doing the job properly

Really good guide, little things like the extra nothing instead of trying for the very long angle. Keep on posting as you are easy to watch and explain things really well

Tremendous amount of effort going into your videos, absolutely brilliant 👌 great quality workmanship, really appreciate the extra in detail tips you have shared, you just gained another subscription 👍 I'm a bit of an old dog but always enjoy being taught new tricks ☺ 🛠

Great, calm presentation. I really like the style :))))

Few comments
1. Use a mask pouring concrete mix, cement dust in the lungs isn't worth
2. Space posts 100mm off the bottom of the hole, there should be 100mm of concrete footing under the post.
3. That timber is WET (9:55), probably best to strip stack it for a few weeks under cover if possible to avoid movement as it dries out
4. If you're going to attach joists/bearers to the side of the post you need a bolted connection not screwed, so the friction between the clamped together members holds the load (not your screw)
The 400ctrs, painting the cut ends, and general attention to detail is good though!

Brilliant video this 👏 great to see all the details and explanations behind them

Should the post not be notched? Just so the beams weight is transferred through the post, not just relying on the steel bolts?

thanks for the great tip on the flat head screws! You have a clear way of getting info acress so keep up the good content. Subbed.

Love your work! Quick question: what’s some methods for leveling post height against the others that spans a distance? Thanks in advance 🙏

That timber frame, even if pressure treated, will not last long. This type of treated softwood support framing will decay very rapidly, especially on the upper face at the exposed gaps.the most vulnerable area is where 2 boards butt end to end. Since the water surface tension resists drying out here. You need to treat it all with multiple coats of microporous wood treatment eg Sikkens range, and give very special attention to the top face of the entire frame. ideally place a membrane strip (such as ProtectaDek) onto the top face of the timber support, before laying the boards. Some pro's will instead treat the top face with 2 coats of bitumous paint instead of using a plastic membrane strip. This helps slow down the decay at these most exposed points of the top face.. After 20 years of laying decks, I only use a hardwood deck on a hardwood frame. It works out less expensive in the long run, Otherwise you will be pulling it up in 7-8 years time.

Surprised to see that you don’t use joist hangers. Do you think they are overkill for a deck?

[Awwwsheeeeeeit]

Have you built the subframe above or below the DPC line? I’m guessing it’s just below it? Will this not be an issue for things such as rainwater? I ask because I want to build a subframe similar to the video but I can only go about 100mm below the DPC line. I think if I were to build the subframe any lower it’ll be at grass level.

Good work guys. Lots of info but missed the post spacings. Need to get some proper site footwear too... IMO

[johnagius]

very interesting would like to know the type of wood used and sizes though, i dont believe its listed here

[DanielaTaylor-jq]

Hex fixings are rated to take a load 👌

[crazycressy]

I see a lot of ppl putting the decking at the same level as DPC .Don't you worry about the splash effect and damp going into the walls ?

[jancooke]

It would be nice if you answered viewers' questions.

Hi There, thanks for your video and tips as you go along building the deck. I've seen in other video's "not yours", they are using hangers in each joist. Do we need hangers or that is overkill since we are not going to put too much weight on the deck. Thanks

[murraymaunder]

Hi What centres do you have your concrete timber posts? Thanks

[peterbonetta]

Im a carpenter, few issues here and i only watched the first 3 minutes !!
1:- use hangers, screwing into end grain is poor especially outside.
2:- your joist centres will be wrong for multiples of 400;s 1st joist 400mm from outside to centre of next joist, 400mm centre to centre from there on !!
hoprethis helps
