  • Repiling costs and suggestions

    Hi everyone,
    I've been gooling the repling topics and have not had much success. I have a old 1910 villa of approx. 140sqm floor area sitting on totara piles, largely (I believe there were some not so good fixes in the past). Section is gently sloping with crawling space. The comment from the building inspector was that the repile should've been done five years ago, however, if it's not done in next 5 years, there probably wouldn't be too much difference.

    Most of the house, when walking on, is ok. Two corners of the house do feel springy, not hugely. I'm certain there are rotten framing and weatherboards around the house. Without any accurate measurement, I feel the northern part of the house is probably sinking due to the rotten piles, hardly noticeable, though. There is some wrinkled wallpaper in one room on the northern side.

    My questions are:
    how much does it cost for a complete repile these days?
    I probably won't be able to finance a full repile at this stage, will a repair (replacing worse effected piles) be any good? How does a repile effect market value?
    Any good repilers anyone can recommend in Wellington region?
    If an earthquake strikes and the house calapses on old piles, will insurance company argue they won't cover the house as damage resulted from deferred maintenance?

    Looking forward to any comments.

    Yes if there is existing damage and there is an earthquake they will not cover it. Insurance companies are doing this in Christchurch at the moment.

      About 2 years ago, had repiled an 80 sqm bunalow of that same era. Quote was 10,500..........but ended up costing closer 15K. The main issue was in the lean-to. Lived in the house with the dipping floor for 7 years, and in prob didnt get worse in that time, or if it did, only slightly. Talk to people that specialise in foundations. Get a few opinions on cost and condition, and what you can expect to happen internally.

        A good option could be to engage a house removal co. They lift the house high enough to get diggers (to remove old piles, concrete etc), hole borers etc under the house then lower it once new piles in place. Easier to achieve a good job as there is space to work. The downside is services will need to be disconnected and reconnected. The scenrio i was aware of was a few years ago so cannot give current $ indication but it was cost competitive with other pilers.

          About $15,000 plus gst plus the cost of the permit in Akld. Give or take and depends on ground conditions, accessibility to underneath and working room. In ChCh the houses are low to the ground so are being done from inside by removing the floor.
          Unfortunately the longer you leave the house the bigger the risk of it remaining crooked as they do have a memory!
          A partial repile is a waste of money you need to get the whole house level. Any repiler worth their salt will not do a partial repile as it will ruin their reputation as they will be fleecing you.
          I seriously doubt that your house will collapse as if there is a chimmney it will be held together somewhat by this. The houses in ChCh have mostly slid off their concrete ring wall, piece of cake to fix if the land is ok.
          Repilers have to have LBP accreditation now and you do need to get a permit for it, an engineer can sign off. If you want to do renovations you will need to get the foundations sorted first.

            You don't need diggers, it can be done manually, labour intensive yes. This person needs a repile and relevel. If the stumps were ok it would just be a relevel.

              Lean-to is usually added on later and at a time when the house is in need of foundation work. The addition is usually built crooked, hard to believe but true. That sounds expensive must've been a big job!
