As bruce stated above, go to purdue. You also need insurance that covers WDI inspections.

It is good to be able to provide all of the services, but that is not always feasible, especially when starting out. The important thing, in my opinion, is that you are able to provide all of the services needed and that the client does not have to cal 3-4 companies to get all that they need.

I subbed WDI insepctions my first year and a half, until I decided that I was going to get enough business to stay busy and justify the extra expense with licensing and insurance. It's not a bad idea to get the certification now, but it is not necessary so long as you are able to still provide the desired services through other vendors.

You are not that far from me. If you decide to wait and need to sub this out, contact me and I may be able to help. I do perform the WDI inspections under a different company entity than my HI business.

I can also give you the names of the companies that I use for radon testing.
