Brick weep holes

[belliott (Bob Elliott, 450.0002662)]

You guys may not see enough brick to even know that there are different kinds of weeps
The one above would never have a wick
And screen is used
Sorry if tour not up to date on good practice
Take a masonry course and get up to speed

It’s obvious the pest control industry is hurting as well… making $3.25 per contraption I suppose could pay a few bills. lol

I ran across my pest control contractor at an inspection today…he said he is averaging 2 jobs a week…he is about to go under… maybe I can show him this to see if he can make extra money…however you can rest assure I wont be recommending them in my inspection reports.

Jeff,

Calm down, I did not start the discussion about weep holes and screens. I just said that " I do not see weep holes every often. I ask questions for the benefit of the the less experienced inspectior. Asking questions even when you know the answer, just might help someone else learn.

Enjoy your cake and ice cream. I am on my to the gym.

Thanks!

Good course, Marcel.

Use of a louvered vent as a weep is shown in the last illustration.

Thanks for all the great advice to all. Not much brick seen in these parts, especially new construction. There is obviously differences in opinion about the use of weep hole screens. There are lots of bugs around here and as a home owner/builder I would consider using them in this area. The plans and engineer did not call for them and neither will I. Thanks

[jshishilla (John Shishilla)]

@mgratton

I don’t know about your area, but shouldn’t there be more clearance between bottom of those bricks and ground.

No the slab is designed that way, just like block on a slab.

Thanks John,

I forgot, not too many basements down there…

Basements are mostly interior pools :twisted:

I see weeps at maybe 1/3 of newer homes with brick veneer that I inspect and always report their absence; and missing or poor flashing installation. Even though there isn’t much that can be done after the fact.

This is a few yrs. old, but same principles are used, or should be, in todays construction.

Inspecting Brick Veneer.

"Weeps
[/size][/FONT]Weep holes are required at all flashing locations typically 32 inches o.c. maximum. They must be installed directly on top of the flashing in the head joints of the brick by **utilizing methods as simple as leaving an open head joint or may include one of **countless louvered, vented or drainage screens available in the market."

[belliott (Bob Elliott, 450.0002662)]

Lots of good information.

My best friend Will Decker :)gives an excellent course on water intrusion and the need {need} for weep holes and having them done right.

Unfortunately some of us stay educated and some of us will continue to keep recommending the old improper methods with an excuse that it is not required in code.
It is a shame, but not all will look out for their clients the way they should, so as to not upset the developer or the Agents that feed them.
John I hope you change your mind and start referring safety , health,and best practice to benefit your clients.
Respect is earned and people know what is right in the long run.

It is note code to require GFCI in an old house , but I hope you recommend it as an upgrade, and I do not even need to explain why, so how come some rolled up screen or Brillo pad is to expensive to recommend?

I come from a brick town, and see poor construction every day,but do not stop educating what I learn.
I just took pictures of a building 4 blocks from me on my phone yesterday of a place where a big row of Brick Veneer collapsed from a rusted Lintel. (no weeps)

Will upload later.(wait a minute I emailed to my self

Here you go and not bad for a cell phone pic (Android / Moment)

Notice the horizontal crack ,5 courses up.

How much would you guys like to bet it meets code

Sorry did not notice earlier as I was not at office before.

Actually there should be a foundation somewhere (haha)
The weep is ok but the foundation is too covered and the lot should be regraded to expose at least several inches.(I think 6 inches is recommended).(need to look that up)

There are numerous designs for weep hole inserts, and depending on the geographical area of the Country, certain designs are better than others.

and one more here;
http://www.tamlyn.com/documents/weephcomerical.htm

I posted this many times.

Weep holes are recommended by the brick institute and required by code.

The requirement of what type of weep holes in brick is left up to a designer or local jurisdiction.
Not one particular type of weep hole design is mandated that I know of. The presence of a weep is all that matters.

That CMI logo looks good Marcel.

@jhaynes

Buck,

There is no need to privately email me and tell me to google weep holes…I have been building homes for 30 years…actual hands on knowledge…I understand the principle of what they are for… if you want to call them out that’s your business but please to lead other to think they are suppose to be there… the only think that will happen is they become clogged with mortar and debris…thats common sense.

Now back to my cake and ice cream

Jeff

The dropped Mortar is called snot ,so quit being one

[jshishilla (John Shishilla)]

Actually the super told me that there was a screen on the interior all the way around. Without xray vision I do not know it that is what they did. He said it in front of my client. If I see the mason I will talk to him. It is logical that a screen would stop bugs but slow water flow.

I will not recommend design changes if the change could be worse than the problem. What works in one part of the country may not work somewhere else.

This is true John.

I see many with no screen ,but have run into buildings along the Chicago river area off McCormick blvd (for the Homies.)where they had to install them later as Rats were getting in through the weep slots.

Those slots are much bigger than standard drill hole size weeps.

I will dig up a photo when I have time as this was a year or so ago that I took the pics of the screens.

Rats can get into anything the size of a dime.

@jshishilla

There is obviously differences in opinion about the use of weep hole screens.

I’m not a “guru”, but I’ve inspected more than 1000 homes in 5 years, 40% of them brick, and I’ve yet to see anything but rope in the pencil sized holes. I’ll risk being called “slack” for not calling out the absence of something never seen, and which must be purchased over the internet.

Around here you may see a few wicks but mainly plastic tubes about the size of a pencil (and usually partially clogged with mortar).
