NuBuild Contracting - Dishonest Builders

Do not trust these builders they will leave you high and dry!. We recently undertook a renovation to our outside step area. We got a quote from Nubuild Contracting to do the entire job. We showed NuBuild the exact finish we required. After receiving the quote we have it in writing that we would only accept the quote should it include a product called "cemcrete" which would give us the finish we wanted. We have witnesses who can vouch for the fact the owner Neville agree to use Cemcrete. We are now at the stage where the final finish needs to be app**** and NuBuild is refusing to apply the finish unless we pay them an additional R17000. We are now left with an unfinished concrete steop (they have not even completed the entire stoep nor have the app**** the agreed screed). They have taken on other jobs and dont have the capacity to do the work and want us to use other subcontractors which would compromise us should the stoep give us problems in the future. Please do not use these people they are dishonest and will say whatever they need to in order to get your work. We have spent years saving up to do this renovation and its immoral people like this that give the building trade a bad name!
