If they are both on the lease and equally responsible for the full rent you hold him responsible while evicting her and can then take him to small claims court to collect if necessary.Not having her on the lease places you in a tenuous position legally when it goes side ways.

Careful in your selection as stains that are silane based (silicon) typically do not breath.I have seen the face of brick and the entire front wall of CMU 'popped' off an elevation due to sealing the exterior of a cavity wall system.My suggestion is to hire an expert such as an architect, building systems engineer or such to give a recommendation on how your wall systems were designed to function.

In a combination of emails, phone calls, and an office visit, I took a three-pronged approach: 1) An appeal to do the right thing 2) A reminder that when I prevail in court, they will likely have to cover all court and attorney fees 3) the social media fallout could be costly.
