If a window in a bounce house or obstacle course is beyond patching (large holes or tears, or dry rotted and brittle) we can completely replace the window with brand new high quality netting. If your window just has minor holes, they can be patched. But for safety, if there are any large holes the window should be replaced. We have a quick turn around time (usually same day), and once the window is replaced, you won't even be able to tell there was damage in the first place. We replace both rainbow netting and window mesh. Window replacements range from $150-$350 depending on the size of the window, and standard bounce house window replacements are $250.
