Unlicensed Contractor

[crackrawksteady 0]

I recently went to scout for a few contractors for my new BTO. Eventually I found a contractor who gave quite a reasonable quote.

His attitude and responsiveness is up to my standard and most importantly he gave good advice to not overspend on the unnecessary stuffs. I have also went to one of his projects and overall satisfied with the works  

However, I found out recently (Google his company) that his company has been suspended by HDB for applying a renovation permit on behalf of a non-registered company. 

Now I am thinking if I should still engage him. What are your thoughts on companies like this? 

Thanks.
