How much should I expect to pay for a 40 square meter stone wall to be repointed in a lot of places
This is a tricky one because its the access and working platforms that have to be secure to work on and off throughout the works ,this will increase the costing a lot.
Generally the cost per m2 lets say on an old town house at floor level i would quote > £38.00 PER M2 but there is a charge for grinding out to consider.
A lot depends on how accesible it is ( as in ground level or needing scaffolding )how much preparation is required and what type of pointing to be done ( brushed, raised, ribbon, cut and raised ect ) as a general guide it could anything from £30 to £90 per square meter. Sorry can't be more specific than that but there are many variables involved.
For the whole 40 square meters, rake out and repoint with materials supplied it would be roughly £2000
All depends if you want cement or lime based mortar but varies from £50-£120 per square metre depending on the style of repointing that you require.
Re-pointing is between £60 to £ 100 per meter square.
£4000 on the highest price per metre
Roughly about twelve hundred pounds
Depending on the hight of the wall and the weather I would expect it to take 3 days for 2 men so around 1k -1.5k
