u/Educational-Wash6598

We just had a whole-house siding replacement done that is around $36,000, and we realized that none of the housewrap was Tyvek which was specified in the contract. They used Hardie wraps (for back walls), and Everbilt and Grip-rite (for sides and front walls). When we found that, we were told they are the same quality with different names. This turns out to be completely wrong and dishonest. We are very unhappy with this as it causes the loss of value and poses long-term risks for a house in the Humid Mississippi. What can we do about this? A redo is not practical, but how much monetary credit shall we look at for this contract breach? Are there any similar experiences here, and how were they solved? Thanks.
