Landscaper or Bricklayer? Quote?

As this is removal of waste primarily, the cost of a 6 yard skip and 3 days labour for 2 men should suffice ... the price of rebuilding of the wall would depend on the quality of the existing foundation , whether you would require 4 or 9 inch wall and brick type of your choosing ...

Hi - where are you located? Best have it reviewed on site - or send photos for an estimate. Type of brick will influence overall cost.

I would arrange for a skip to be put as close as possible and take down a bit at a time unless it safe enough to push over once cut all roots and if okay burn the gree part if not okay then arrange for its removal all down to footings check there sufficient then re build

For myself to complete the job, would cost between £2000 - £2500

Cost would depend on some factors, would you be using the old bricks to rebuild wall
Is the old foundation still in good condition to build on

You can usually find a company that does both as one job (like us) saves on costs and dealing with multiple trades

The size yourve given suggests it is a double skin wall.all I all it constitutes to 40 square meters of brickwork. This is a substantial wall.itwouldnot be prudent to give a complete cost without visiting site. The demolition side would require a excavator to teardown and load skips or pile ready for a grab wagon. the cost of a digger saves alot on labour loading waste. To lay 1000 bricks you'll pay between £600/£700 on private work.this is labour . All material are on top of this.also you would have to check if the footings are in good order to take your new wall . I hope this helps
