Im very sorry to bother you but I wandered if I could ask for some impartial advice, as Its very, very hard to find nowadays!
I am currently in the process of buying a leasehold flat. I had a homebuyers report that recommended a wall-tie specialist inspect the building, which was built c.1930.
The report came back, and said that corrosion of the wall ties was found (using endoscope) and recommended wall tie replacment.
The freeholder of the building is also a surveyor,and he was very shocked, saying that the wall ties were fine, as there was no tell-tale horizontal cracks in the brickwork. Therefore refusing to pay for replacement.
He offered to remove some bricks so I could see the ties for myself. It hasnt helped really as Im now even more confused. The ties are metal rods about 5mm in diameter with a right-angled bend at either end, that beds into the mortar. The mid section of the tie apear to be covered in some superficial rust, but the part that is in the mortar is quite corroded but would still appear (to a layman!) to be structurally sound.
We have only inspected a couple of ties on the back, south facing wall. The freeholder insists the front north wall would be fine, as it doesnt get the weather.
Therefore the freeholder is still insisting that the ties are fine, and if they have lasted 80 year like that, they may well outlast the building!
As I hope you can understand, we are in a predicament, as we have two conflicting opinions, from a wall-tie specialist and a surveyor, and we dont know what to do.
We dont want to move into a building that is structurally unsound, and that we will be liable for 50% of the maintainence cost of. We also dont want to loose the flat over an argument such as this.
If you have any advice for me, regarding whether the wall ties would be ok or not, please could you let me know.
I thank you so very much for your time.
