Alarming crack...
....no, it's not J-Lo. I've discovered a worrying crack in the party wall
on the top floor of my new house. It's near to the outside wall, about 3ft long and 1-2mm wide. Goes at a steep diagonal starting about 6" from the outside wall up to about 2' from the outside wall. Looking along the outside wall, I can see that it appears to have bowed out slightly, which is I presume the cause of the crack. The bowing appears to be limited to the upper part of the wall. Not sure how to proceed now. Just bought the place so I'm reluctant to get the insurers involved as they may well decide it started with the previous occupants and start a battle with previous insurers. Also, it's a party wall so that could make things complicated. What could cause this, and how would it be treated? I imagine what will need to be done is one of those big metal X things on the outside wall to hold it all together. Is that an expensive job, or even a DIY job? I'm slightly tempted to plaster it up and keep an eye on it for 6 months, but that's obviously a bit risky. Any ideas? John |

You really need a structural engineer to report on the crack and the bowing and monitor it. There's no point putting a bit metal X thing on the wall if the wall isn't held together sufficiently to not fall apart, or if there isn't anything inside to tie the outside X to. An engineer will be required to satisfy Building Control and insurance companies. | I'm slightly tempted to plaster it up and keep an eye on it for 6 | months, but that's obviously a bit risky You could get some tell-tales / crack monitors from York Survey, stick them across the gap, and photograph them every couple of weeks for six months. The other thing you should do is to look at the wall from the neighbour's side, and preferably put tell-tales on that side too. If the crack goes right through the wall and is moving, that is a Bad Sign. Owain |

I imagine what will need to be done is one of those big metal X things on the outside wall to hold it all together. Is that an expensive job, or even a DIY job? Those big metal "X" things went out in Victorian times as I understand it. iirc, "X" things were placed back and front of a property. A long metal rod was passed through the entire house and a nut placed either end. The rod was then heated ro red hot along its entire length by a number of workmen with blowtorches, while nuts were tightened either end. When the rod cooled it contracted, thus pulling the outer walls inwards. sPoniX |

From what you say though, it sounds like I'm going to have to call in the insurance company and let them deal with it. John |

If, every time you look at a house you have a full-structural done and walk away from the house as a result, that's a bloody good way to end up homeless and poor, having paid out every last penny to useless surveyors. I had a full-structural survey done on the house I live in now (built in 1827, renovated from a ruin in 1999). The surveyor (recommended by the solicitor) got the direction in which the house faces wrong by almost 180deg, and stated in writing that the loft insulation was 200mm deep when actually it was entirely absent. Neither of those were actionable---it cost me less than half the cost of the survey to insulate the loft, and it's blatantly obvious to anyone looking at it that the house faces SSW, not NNE---but it does make you wonder what else on the survey isn't worth the paper it's written on. -- SAm. |

Your 30mm cracks make my 2mm seem a bit feeble! I'm trying to work out, as you did, why the bowing has happened. It's between the roof and the level of the top floor, with no signs of movement in the two storeys below this, so I doubt subsidence. I suspect it could be something to do with the roof, as the surveyor did spot that the roof had a slight sag as a result of someone removing one of the diagonal bracing timbers in the past. We were planning to get that done as part of a loft conversion, but perhaps it has had the effect of the roof pushing outwards on the top of the wall leading to our problem. Anyway, general question: what would be the most sensible sequence of getting the following people involved: Engineer Insurance Neighbour (remember, its a party wall that has cracked and the bowing is on his side too) (Bearing in mind that we only moved in a few weeks ago, and perhaps don't want to get the insurers involved at all). |

Then you will have to contact you building insurers who will tell you to get a foundation/soil engineers' report.

I'd just ignore it if I were you. All the houses I've ever owned have
had alarming cracks, bulges etc. thats why they were so cheap. They still have them and I made a big profit in the process. The last one had cockroaches but I did get rid of them. Last but one had a half collapsed roof with sagging ridge like a saddle. Its still there just the same and uncollapsed nearly 20 years later. Just check at 6 month intervals to start with, then 1 year, 5 years etc. Start panicking if there is rapid change - sound of rumbling masonry in the night for instance. heers jacob |

Didn't chekc loft space, ladder was too short. Didn't check floorboards because of carpet. Didn't check built-in gas heaters because they don't do that... Didn't check plumbing... geta plumber. Didn't check electrics. get an electrician. Actually not sure what they did check in the end... |

Yes, this can happen, and was one of the things my struct. engineer checked first. Though I'm still a bit confused; the bowing is between the rafters and the top floor joists. Surely if it were the roof memberss pushing outward the bowing would be from the very top of the wall, not further down. |

The crack is not old, but it appears the bowing of the wall is; there is a built-in wardrobe in the chimney breast alcove where the wall is cracked. The side of this wardrobe, now I come to look at it, is noticably thicker by about 3cm in the middle, ie it follows the line of the wall and nicely illustrates the degree of bulge. The built in wardrobes look about 10 years old and I suspect the bulge is older than that. The crack though, does look recent; it is clean and the wallpaper that has been ripped looks freshly ripped. I think what I should do is pay for an engineer's report and ask him to consider it in relation to the roof problem and how to sort it all out as part of a loft conversion we will hopefully be able to afford in a year or two. Thanks, John |

If, every time you look at a house you have a full-structural done and walk away from the house as a result, that's a bloody good way to end up homeless and poor, having paid out every last penny to useless surveyors. Seems to me that a much better way forward is to get the minimum building society valuation done by the surveyor, and then commission a separate proper structural survey by an engineer. I did this recently; it only cost me 211 quid on a 60K house - much cheaper than the surveyor's version - and saved me a very expensive mistake. Doesn't catch timber/damp problems admittedly, but the most expensive problems (subsidence etc) tend to be structural anyway I had a full-structural survey done on the house I live in now (built in 1827, renovated from a ruin in 1999). The surveyor (recommended by the solicitor) got the direction in which the house faces wrong by almost 180deg, and stated in writing that the loft insulation was 200mm deep when actually it was entirely absent. Neither of those were actionable Why on earth not? especially the insulation? I once had a valuation done years ago (which is perhaps the key to this!) where the valuation was based on the property being double glazed - it wasn't. A couple of letters to the surveyor (nobody legal involved) brought forth a compensatory cheque. David |

If you buy a house with a fault like that and report to your insurers: 1. its pre-existing, so is uninsured 2. you now have a house with a history of struc probs, so knock a few arms and legs off resale value 3. I dont know but insurers might possibly insist on surveying plus repairs if they are to cover further movement 4. your insurance premiums will quadruple. 5. most insur cos wont touch you with a bargepole NT |
