Tried to send pictures but they won't copy.
My house is around 75 years old. I was getting dampness in on upstairs, front, north wall. Had tuckpointer out in Oct ’08 to tuckpoint inside firewall and waterproof after which I re-plastered the walls. Then in spring ’09, I noticed alot of dampness on ceiling and more on the front wall. Tuckpointer came back and said now it is the roof. Had two roofers out, both members of the BBB and both said my 14 yr. old composite roof is not leaking but they could not see where the tuck pointer did anything to the firewall. Called tuckpointer again but he has not shown up yet. They think the dampness is from the tuckpointing or the wet, saturated brick on the front, north wall. From the pictures I tried to send, you would see long, wet lines of saturated brick coming down from the top crevices between the decorative stones. This has been this way for several years. I did have those stones (not the bricks) cemented earlier but it did not stop the dampness inside or out. I’ve had other roofers and tuckpointers out and no one seems to know how to deal with this. I think this must be where the dampness is coming in. (At one time, I did have a window air-conditioner that vented straight up towards the window frame. That caused a lot of dampness in the wall at that time, until I changed air-conditioners.) Is there any way I can repair or replace this wet brick? Who would I call? The ceiling is 16 inches above the window frame and I assume there is a crawl space above that where water is getting in and running across my ceiling and causing the plaster to dampen and loosen. I would appreciate any help or other suggestions. The weep holes are on the top, sides of the building and all the contractors did not think it was unusual that the front wall of this 75 year old building has no weep holes.

Tuck pointing has nothing to do with dampness entering into the walls. The brick weep system is blocked and any wet brick is leaking into the wall.

So we need some more info.

Is the brick wall a fire wall between row homes? or is it simply the outside walls of the house?
By the sound of it your describing a row type home with brick firewalls that come up out of the roof between the units.

Is the brick exposed in the inside of the home or is plaster/sheetrock covering this?

The weep holes your describing near the top of the walls are not weep holes at all. They are the side wall vents for the attic space that is there. This is assuming the vents are close to the roof area.

Weep holes would only be seen near the top of windows and doors as well as the floor line near the first floor level. Many times these holes are filled with cement from well intentioned contractors thinking they are fixing a poor cement job. IN addition many older homes used rope as wicks that often poked through the bricks. This method is no longer used as the rope does not last nearly as long as they thought it would.

You can visit www.bia.org on the web and you may be able to get more answers, but without knowing exactly what type of home you have it is difficult to know how to fix it.

But in any case, DO NOT use any kind of brick sealer. This stuff regardless of what they claim does not work and in many cases can destroy the surfaces of the bricks and more so if the brick is old.

The building is a single, two-story residence, all brick, with a flat roof and decorative stonework on the top of the front wall. The inside walls and ceiling are plaster.
The wetness on the brick comes down in streams from most of the crevices between the decorative stone on the top (the tops of the stones are cemented). The wet streams stop above the brick that frames the window area. Are you telling me that the weep holes above the windows are stopped up and the water has filled up in the wall all the way up to the top of the brick wall below the decorative stone where the brick seems the most wet? I seem to get more and more plaster damage every time it rains. Can a tuckpointer make new weep holes above the windows?
