When we laid our first paver walkway about 9 years ago, we had already talked to people in the biz and read all the material we could on installation practices. The first one went very smooth and all of them after that seemed to increase our knowledge exponentially.
I had my fears for the certification class because:
*We already have a proven system that works.
*Nobody , I mean nobody, has ever asked me if I'm ICPI certified.
I sell our jobs based on the knowledge I have and the accumulating referrals from past customers.
* I always look in at our jobs from year to year and all seem to be holding up strong.
Just can't seem to pay the price for a certification when I'm too old to change my ways!!
Here's our first walkway. Still solid after all these years.
