Did you post this pricture of a deteriorating lintel?

If I can find those pictures I will post them. Thanks for the memories

Cool I would love to see them as we all would.

These are the pictures from yesterdays FEEMA inspection.
I was shocked at the displacement all over this building complex from lack of flashing ,downspout placement,ac units not sealed and poor roofing.
It shows how problems develop over time from more than one issue.
looking at that casement you can see why I figured the other one would cause problems also from the original post.
This is a 2 story duplex building.

What is FEEMA BOB?
I am in Montreal Quebec and nor familiar with that organization.
Are they out to help flood victims and hurricane disaster families.
As a first response to shelter and food.
Yes that residential building was built bad from what I see and maybe underlying ground issues aiding in the movement.
Clay, lack of drainage, pyrite.

Someone please explain to me why my post are coming back to me over and over again.
I will post my problem on the message board.

Given that there is extensive oxide jacking at the lintels above windows, and taking a close look at the openings below both cracking sills, it still seems to me that it's much more likely we are looking at oxide jacking at rusting lintels above closed-in AC openings than freeze/thaw jacking due to water intrusion at the windows:

OK I am going to come in and hopefully explain myself with out putting my foot in-my mouth.
The information I am giving you was passed to me through learning by piratical not theory.
> Observation and explanation from foreman and lead Masons as I learned all my life.
>ON THE JOB TRAINING.
>I have seen similar problems and asked why.
!> look at parapet wall and roof's copping.
I surmise that weather interned the wall through copping and flashing and roof flashing mostly and caused lateral pressures on parapet as frost built up.
There was also a lot going on for as you mentioned the lentils swelled applying uplift and movement from expansion or contraction of the brick field all lead to what problems you are looking at.
I am just observing the photo for what I think is an answer and please there are others that have more to contribute besides myself.
I do not pin point 1 particular weak link in the chain so to speak but several factors combined to allow this much damage to take place.
I will state that proper maintenance would have controlled the erosion.
A manageable yearly or biyearly or even every 4years to inspect and repair the problems.
It would control large events such as this from happening and aid the building exterior to stop it (the cracking, shifting, uplift, movement dead in its tracks or at the very least slow down the erosion..

Mr.Thomas.
I forgot to mention ,windows the weakest link in the chain on brick veneer walls.
After copping .FOR ME.
I will post last years example of an estimate I preformed.
Look at all,all the windows in the building.
Look for any and all openings.
Does not matter how small the opening and pay attention to the ''upper part'' of the frame please and go out side with good binauculars and look at all lentals for any breakage or missing masonary were the lintil sits on the brick 4 inches or maybe more.
Just an idea.
If you do not get back to me its OK but please post your findings for all..
>caulk that has shrank, caulk that has cracked etc. look at windows with a fine tooth comb so to speak.
The weather enters the wall cavity through openings in any way it can enter.
In the winter the inside being warm out side being cold the weather (air) that has entered goes up the walls cavity being drafted by the warn inside wall.
The cold brick surface attracts the moisture in the humid air and attaches itself to the bricks surface and frost forms.
It goes trough cycles of thaw and freeze all winter long and expands the brick and breaks down the nail for the ties or even the ties themselves depending what they are made-of.
So please pay attention to the windows for I have seen brick field repaired only to have it break down again shortly after with the owner not knowing why.
An engineer could not explain why only how to repair.
But a window installer and mason told her and explained the process to her and I was on the money in that case.
It causes havoc inside the walls cavity. breaking down brick pins or anchors (wall ties) nails what ever you want to call them.
I can not tell you if you need an engineer but a good chimerical building inspector would give you a good heads up.
Good luck and if you can post total pictures of the building-north-east-West-and South I would-love to take a look.
