Q.Will mango tree nearby house cause foundation damage
I am building my house where I have one mango tree about 4 ft from foundation. So what should I do to prevent my house foundation from mango roots without cutting the tree? Thanks in advance.

While mangoes are not considered a tree with a particularly invasive root system, it is recommended that they be planted 25-30' from houses, because they are quite large. If the tree at your building site is young, can you have it moved? If not, you can install a root barrier between the house and the tree.
