Bulging Brick Wall (built 1901) in Brooklyn (side wall)

16 years ago

I am a homeowner in Brooklyn, NY - area where many townhomes (brownstones) exist which date back to 1900's.

I have had this home for 2 years. It is a 3 story attached home. 2 Years ago, I renovated the 1st floor and recently I renovated the basement (just as a background info).

Much like most homes here - my home is attached to homes on both sides. On one side, the townhome is identical in height; on the other side, however, there is a 2 story home (shorter) exposing the top 1/3 of my brick home to nature. This side wall is bricks covered by stucco and is the matter for my writing.

There seems to be a bulge on the side of the wall exposed to air - seems to be in the center area (2nd to 3rd floor area) of the side wall. From the roof top (top to bottom view), I see that the stucco where the roof and wall meets is very brittle (I can easily take chunks of stucco off of it with my own hands). It seems to bulge out as the wall gets few feet lower from the roof and then back to "more" normal (pregnant look). I also looked at from my backyard from a ladder (side angle/view), and you see the bulge although you have to look at it very keenly to see the bulge. It isn't so bad that it is readily noticeable.

I had 2 masonry 'contractors' came in for their recommendations.

1 - one said it is very bad and said it needed complete makeover. He asked if I did renovations recently and how the inspector missed the bulge 2 years ago when I bought the place. From my memory - I never til today looked at the side wall, so I am not sure if this is a new problem or if it was always this way when I bought it. As I stated earlier - I did renovate the 1st floor and basement but am not sure how that would impact the bulge. When I balked at not having necessary funds to totally re-do the wall, he said I should at least do re-pointing for $8500. Intent being "stop the bad progression of the bulge" and make sure it doesn't get worse. I wasn't sure how re-pointing would just stop the situation from getting worse.

2 - one said it's not that big a deal but he recommended that I "water proof" the entire side wall with "Terra" (?) coat and re-do some stucco in some areas needed for $2600. He did not think re-pointing would do anything since bricks are covered by stucco all around.

One other general contractor who is a family friend looked at it and said neither of the above proposal would do any good and just leave it alone. He thinks it will be fine for a long time. Thus, I have 3 vastly different advices.

Any experiences out there with old brick homes with this sort of problem?

thank you in advance

Although some masonry contractors are very knowledgeable they have widely varying levels of expertise. Since you have no consensus, I would get a structural engineer to evaluate it.

I too have a brick/brownstone rowhouse in Brooklyn. Although old brick does absorb moisture to some extent, stucco and/or waterproofing over brick is unnecessary unless your interior walls are getting moisture damage. Otherwise, brick should be left exposed to release the moisture. Stucco and waterproofing often create a moisture problem with your interior walls by trapping moisture in the brick which can't evaporate.

Pointing is not going to do a thing for a bulging wall. You may need pointing if the cement is missing/crumbling but that's a separate issue.

It's not unheard of that side walls fail to the point of needing to be rebuilt and you might need to do that but consult at least one engineer to determine whether something something less extensive will work. If you need to rebuild, get at least 3 prices for the job and check references.

Just curious: Re the contractor who wanted $8500 for pointing, how many and what size walls would he be pointing for that much. And how much did he want to rebuild 1 story of 1 side wall ?

I think you need to keep getting opinions until at least 2 of them match.

I agree, you need to have either a structural engineer or an architect who works a lot with older buildings look at the situation.

The first thing that needs to be determined is if that wall is in motion, or if the bulge is something that's existed for a long time.

If it's in motion, you're going to need to move quickly.

It would be speculation for anyone here to say what the reason for the bulge is. It's likely a bowing out from settlement, as you say. Is it possible for any water to have entered in the past and caused the wall to sag? Is the plaster hollow sounding when you knock on it? I had a bulge and spalling at the top of my plaster walled stairway at the ceiling. It seemed that the cause was that a crack developed in the plaster and with the moisture in the house migrating in and through the crack was exposed to the cold in the attic (through conductance in the framing and lack of sealing) and gradually weakened the plaster and it swelled and bowed. I just chipped out the plaster to a solid base and capped it with overlapped fiberglass mesh and Durabond 90. You could drill a small hole and prode about to determine what you have. I gather it's your intention to eliminate the bulge before you paint regardless of how big the problem is. If your case is from settlement, you may end up with a large hole by the time you remove the bulge. I posted a message on the thread on this page that has to do with repair of plaster walls. I referred to a Ask This Old House episode in which Tom did a repair of a large hole in plaster wall. Ted

The derating is the percentages of the optimal installation load. Where human safety is involved and installation is not supervised by licensed engineers and actual testing performed to verify the installation, it is typical to allow loading of anchors to not exceed 10% of the ideal installation strength. For supervised installations the loading is normally ~12%, and for non-life type loads 25%. You do not get a lot by doing the testing, so it is rarely performed. It is cheaper to just add enough fasteners to meet the 10% rating. The derating makes up for the variation in installation (holes size, smoothness, variation in concrete, installation technique, etc) and the lack of any testing to ensure the actual installation. In many cases even the strength of the concrete the anchors are installed in is not reliably known. To be allowed for use the devices are required to be listed by a recognized testing authority and they must be installed with full compliance of the device instructions and any special conditions in the listing. Listings typically list optimal load ratings for the anchors in various strengths of concrete. Other conditions to meet the listing are device spacing from edges and other fasteners and device depth. Only a few people died before lag shields were disallowed and more secure fastening means required. In the overall scheme of things the cost difference per job is very small and the gain in safety has been excellent. Deck collapses from ledger pull away have significantly decreased. The most recent failures have been pulling away of entire band joists. There are probably going to be some additional changes in a few years if the problem persists. I know many posters here are not deck builders, but at least one above is and appears proud he does not know what he is doing. I hope he has good liability insurance.

In Bardstown, Kentucky, there is a home owned by a relative of Stephen Foster, where he wrote "My Old Kentucky Home". This home has large metal Stars on four sides of the home. Being from Texas, I asked about the stars. Turns out there were cables going through the house which turminated through the stars. The cables were threaded for some distance on both ends. The cables and stars were used to pull together buldging brick walls. Many older brick homes built in the early 20th century and earlier were actually three courses of brick. The outer and inner walls were vertical and an inner course was horizontal. You need to consider how the house is constructed to determine a fix.

You need a local structural engineer with experience in the housing of your area. It might be fine, it might be ready to collapse.

Could the stucco be coming loose from the bricks, much like plaster can bow on an interior wall? If so, I would go with the third recommendation, do nothing.

"Could the stucco be coming loose from the bricks..."

A distinct possibility.
If you are worried enough to do some work, remove some if the interior wall and check from inside.
