Am a certified tile installer, i install both:
*wall and floor tile......
*granite, carpet tile,
*wooden tile,... Etc.
I like analytical planning, testing of designs, size, if it suits the required place of installations... Also the use of machines, blueprint, plan's, equipment, in carrying out a successful work done is not a problem or challenge ... I also go inter-state's incase if the work is not at your current site
