the wood frame starts from the top of the basement window. Thats's where the build out ends. and the crack start right under neath the build out. SO the crack in the brick veneer has concrete on the other side all the way.

@ jim: I appreciate your interest and hopefully you will have a clue to this crack. no the indoor crack is not visible from the outside and the outside crack is not visible from inside. If you are standing indoor facing the indoor crack, the outside crack starts in the brick mortar is about 5 feet on your left. and ends within 2 feet of the crack. The crack near the wood frame of the build out is wider and almost hairline where it ends. it ends on the left side of the basement window that you see in the last picture. The wood frame (of the build out) starts from the concrete. It sits on two (overly done - according to the structural engineer) steel beams. If you have a phone number i can reach at, i can call you if thats not a problem for u.

@ Jim - thats a concrete basement wall. Just painted. Looks like it opened 2 ice and every time instead of a proper fix they just caulked the gap. We had more than average amount of rainfall in last 30 days but there have been no sign of water leakage.

@ palm: what are the things i need to worry about more? i indeed hired a home inspector. I called 3 foundation company folks to give me an estimate in the worst case. I hired a structural engineer for onsite visit. I sent the same pictures to another structural engineer for evaluation. None of them could find any smoking gun. From the first look of it, it seems like a shifting foundation. But no other signs of foundation shifting is visible anywhere else in the house. Here'e the opinion i got so far: 1. The first crack above the window is probably caused by the rusting lintel. 2. The second crack from underneath the build out do indicate differential settlement. But foundation at the the direction of differential settlement seems to be all in the same level. (measured by a foundation contractor - the laser travels along the same mortar join from the start of the crack to the end of the wall.). So the opinion i got here: - can be caused by frost heave. - can be caused by expanding/contracting building frame - the movement in the cantilever. - expansion/contraction in the wood frame of the build out. - the final one, which i think might have been the cause: there might have been a failed waste line nearby where the line connects to the sewer. At the location of the hole that you saw in the picture, the waste line connects to the sewer. I should mention here that the roof is almost falling off and the gutters are absolutely not working. I posted this in this forum for advice and recommendations. I know pretty well that this is just what it is - a piece of opinion. There are many expert inspectors here in this forum who might see something what others did not. I am not going to buy a house without having it inspected by an inspector and other qualified engineers. By the way - the inspector who inspected the did not have a clue as to the cause of this crack. He advised the crack to be inspected by a 'qualified' engineer too.

Thank u. appreciate your prompt response. the house is 13 years old. the words would be 'build out' and 'interior' - sorry for the typo. i don't live in this house yet. This is a foreclosed property which has been vacant for less than a year without heat and AC. I made an offer on this house which has been accepted. The picture of 3 elevations (front, back, right- where all these problems are): The right side is almost like 65 feet long wall and almost 25-30 feet above the ground. Around 18-20 feet of it is brick veneer and the rest is siding. Click to Enlarge 29.29 KB Click to Enlarge 28.89 KB Click to Enlarge 44.24 KB

thank you much for your so prompt reply. 1. Two bricks seem to be off little bit. Otherwise its a single plane. The two edges of the crack mostly will meet on one plane; 2. The gap is indeed wider at the origin. It actually originates from underneath a build out which is built on 2 canti livers. It almost looks like it is crawling towards the nearby window. I did consult with 3 foundation contarctor and 1 structural engineer. All of them were baffled and puzzled since they could not come to a conclusion what was causing that crack. One of them measured the level of the house along the mortar joint. Even the pattern of the crack indicating a doward movement on the right, the house seems to be levelled all around. The structural enginner looked for bulging and leaning. She did not find any, either from inside or outside. This is a forclosed property that i am thinking to buy. The house has been vacant for last 1 year and did not have heat or AC. The roof is falling off and the water from the roof coming to the wall at this point. The big hole dug nearby the area - (its int he picture) is a mystery too. One guy suggested, it might be for an egress window. The other guy suggested tht it might be for checking the waste line pipe (where it connects to the sewer). He suspects taht at one point the pipe might have gone bad. Doe it give you any more information?

Posted 05 May 2011 08:46 AM I have attached photographs here: Little background: There are these 2 stair step crack in brick veneer; One of them start underneath a buld out and extend almost to a basement window. The interior of the corresponding wall does not have a crack. The other one starts from the top right corner of a basement window and extend to the edge of the build out. The interiror of the basement concrete does not have a crack. However the interiror of the basement window does have a crack that starts from the right lower corner and extends to the flore. There are no other crack in the exterior of the whole house. There are no other crack in the exposed portion of the basement interiro concrete. The problem looks like localized to this one area between the build out and the basement window. The basement wall is almost 60 feet long and get sunlight half of the day. I have had 3 foundation reapair contractor evaluate the situation and 1 structural engineer. Initially they all thought it was a differential settlement but after looking at the interior and other areas of the house they could not come to a conclusion. The waste pipe seems to be running underneath the basement where all these crack are located. Anyone familiar with such situation. Any opinion or advice would be highly appreciated. thanks Click to Enlarge 33.15 KB Click to Enlarge 32.43 KB Click to Enlarge 26.6 KB Click to Enlarge 44.24 KB
