At Heaven's Best, we believe in being upfront with our customers. With that in mind, it's worth noting, not every stain can be physically removed. There are unfortunate instances when a stain is irreversibly set into a material and removal can cause damage to the material itself. However, more often than not, Heaven's Best is able to remove spots and stains and when we do, we proudly attach our Two Week No Spot Return Guarantee to each and every cleaning. We stand behind our work. If you find a spot has in fact resurfaced, it will usually do so within a few days' time (after the cleaning). Rest assured, you need only notify us! If any of the same spots that we cleaned reappear at any point in the first two weeks after the cleaning, call on Heaven's Best and we will make good on our pledge: we will clean the area again—for free! That's a guarantee you can believe in. Your satisfaction is our highest priority.
