Flashing

What type of flashing should be placed around this window prior to the brick installation? I know what was used is not correct.

Flashing.pdf (190 KB)

All window and door openings should have properly flashed steel lintels. I don’t think the brochure David posted illustrates brick on masonry…I believe in the case of your window it would be acceptable to embed the flashing in mortar in a horizontal cut in the masonry above the lintel with the flashing bent to lay on top of the lintel yet underneath the brick…Maybe we have a mason on the board that can confirm this. Also, the flashing shouldn’t be aluminum because aluminum will corrode when embedded in mortar.

Hi John, That is definitely an intersting find on that photo.

I have found this for you that might help.

You must use continuous flashing under the first course of brick under the sills and heads of windows and doors in a brick veneer wall. Do not use asphalt impregnated felt. Have the flashing extend to the exterior face of the masonry wall. A self adhered bitumen type is preferred (IPCO flashing or W.R Grace Perm-a-barrier) / otherwise set flashing in a continuous bead of sealant to prevent water from finding its way under the flashing.

In your case, the back up is concrete, so you would have to have seen something down this line to be correct application.

A termination bar could also be used and the flashing I would reccomend would be a 3 oz. copper fabric flashing.

This might also help.

Hope this helps a little.

Nice PDF Marcel.
Thank you.

:D:DBoth PDFs were good thanks:D:D

No slight to David intended.

I just already have that one.

Thanks for the great information. I am still unsure of the proper method for sealing (flashing) this particular window. Considering it is installed on a treated wood frame attached to the concrete foundation wall, how would the flashing be secured to the concrete? The approved method for sealing the sides of the windows? I know the method for sheathing mounted windows. Apparently I need to recommend removal of the brick to complete proper flashing of this window.

John,

Does this help?

David,
Thanks for the PDF. I am still unsure of the correct method for sealing the window sides on the concrete foundation wall prior to the construction of the brick veneer wall. This “builder” has placed flashing and weeps at the windows located at the front of the home that are covered with brick. Although it is difficult to determine if the flashing work is correct.

Here’s another resource: http://www.maconline.org/tech/tech.html

John,

Here is the spec sheet for that particular material…

As I stated earlier, I’d simply call out the entire building for an evaluation by the municipal inspector.

Your report will be endless for this nightmare.

Well, between all of us, he should have plenty of details. ha. ha.

Here is more that might help.

As though the municipal inspector will knowe any better…in most cases, that would be the last person I would call. They would look quickly and say “OK, there’s flashing, goodbye”. Municipal inspectors inspect for code compliance only, not quality and workmanship, and there is a huge difference between the two. Minimum code compliance does not guarantee a satisfactory result.

I see they used brick lintels. The head flashing and weep holes should probably be above that. Head and sill flashing ahould have bent-up ends (end dams) to prevent water from flowing sideways and missing the weeps. I’m sure the pdf’s offered showed that. One might stick the jamb flashing to the concrete with some sort of mastic, but I don’t think it’s necessary. There should be a water barrier which laps over the flashings, usually felt or house wrap. I’m sure the pdf’s showed that, also, Gee, maybe I should loiok at them! I did, and one did show the end dams, one didn’t, and one was too complicated to find what I was looking for.

I would print out these PDFs and hand them to the builder and ask them to explain how they have complied with these specs.

Put the liability on them.

The ‘Fortifier’ site has some good graphics. Thanks, will save to the favorites.

Linda,

That’s “Fortifiber”. Your welcome…anytime.
