With the exterior of the house being cement block, you need to install wood firing stripes to pack out the wall and give you wood to install any type of siding. My best advice would be to visit NARI.org to find a certified contractor near you who could come out to assess your home and discuss if this is a DIY-friendly job. Siding installation can be tricky, and it's nothing to skimp on--improper installation could cause big headaches down the road.
