The site survey form gives our design team the information we need to maximize the result of your project. The site survey is ideally accompanied by lots of photos....the more the merrier. Take photos of any specific problem areas. When taking the photos, think about taking it from far enough away that we could drop a mat into the photo and still see at least 5 feet of floor on every side. Take photos from every angle. We will make photo renditions so you can see how great your entry can look. Also try to send us a CAD floor plan. We may, have a site survey specialist confirm measurments once we have an order. Always feel free to call us at 888-331-3100 and we'll walk you through the process.
