Finishing off a new house, and the young (but really good) contractor has never built a screened porch before. Must be an old folks thing. The question is: how to finish off the bottom of the screen? The bottom of the porch has a 2x4 about 2" off the ground. Don't know whether to attach there leaving a gap (that the cats could squeeze through) or something else. Any ideas and successful applications appreciated.

Why would you leave a gap in a screened porch?

Anchor wood to the concrete and extend screen to concrete.
The best thing is to walk around and see screens you like and see how it was done.
If you want no gaps, you will need wood on the concrete.

Need to remove that railing, doesn't look like they did a great job on it anyways. I'd use treated, or cypress/ cedar 2x4 on the bottom anchored to slab. You can run the screen all the way down to that or use plywood to make some panels that come up a few feet.

Either way you would regret having that gap. Also i'd use the plastic screen material. I used the metal the first time thinking it'd be stronger but it shows every kink and bend. The plastic is more forgiving.

Why would you leave a gap on a screened porch? I thought the whole purpose of screening a porch was so you could enjoy fresh air without mosquitoes pestering you.

He can't figure out a screened in porch and you let this sum bitch build a house for you?

I don't think insects can fly below 3" from the ground so you should be safe.

Have screens built in panels so they can be removed and hosed out, number them so you know where they go. Makes it easier to replace a torn screen too. The only screened in porch I have ever seen used had this, the panels were about 4x10.

Just telling OP to flash it using a fun visual.

I wouldn't want exposed wood directly on a concrete slab because it increases the chances of rot even if there is no standing water. I assume that's why the contractor kept it up 2".

Personally, I'd just screw some "L" flashing that's easily removable on the exterior side. Keeps shite from coming in and when it's time to hose down or blow off the porch you can remove a few pieces of flashing to let the debris (and water if hosing) out.

Contractor is highly recommended and has been a dream to work with. But apparently, folks don't build screen porches anymore, opting for open air kitchens and the like. In his 20 years, no one has asked for a screened porch. He also mentioned wood on the slab as a solution, but said that would eventually rot.

Down here they are usually aluminum framed. Wood framing is typical for a lattice wall.

He's right. Moisture from humidity would sit in that crack between the wood and slab.

You could shim the gap with another 2x and some 1/2" board but you'll have to replace that bottom 2x once you start seeing the rot (purely aesthetics).

Like I said earlier I think your best bet is to have some type of fascia on the exterior side to cover the gap. Do you have a pic you can post or can you describe the edge condition?

It will, but using the right wood it will still last quite a while.

On second thought I'd look into using some composite studs. They are expensive but probably worth it in the long run.

Lowes

Bottom line is leaving a gap that large defeats the entire purpose of having it screened to being with.

That's a good idea, but he'll still have about 1/2" to fill. Maybe a backer and 1/2" caulk bead.

My screen porch has treated & painted 2"x 4"s attached to the slab. No signs of rot yet in 14 years. The screen is attached to the 2x4 framing with stainless steel staples. Then a I ripped down 2x4s into 1/4" strips to cover the staples and screen edges where it attaches to the 2x4 framing.

Construction looks similar to this google pic
