As per checking your site (http://homesolutionsdetroit.com/), I noticed that the form is embedded using the <script> code. Can you try to re-embed the form using the iFrame embed code and see if this will fix the issue? To get the iFrame embed code of your form, just follow the instructions provided in this article: Getting the Form iFrame Code.
