it's worth to have your inspector to check. it's around $300. richcraft qulity is not so good. if you cannot find the problem, it's your lukey, but i doubt...my house is bulit by richcraft, i had basemnt concrete wall leaking. unfirtunately, my inspetor didn't find it. you should try a good one, and also check by yourself carefully. trust me, i have been working in architectural field 25 years.
