We do in rare cases, but you need to know a few things first:
Inflatables purchased at Walmart or Costco are considered residential-grade inflatables. They are made from inferior materials, and are not meant to last more than 1 or 2 years. If you've managed to get more than 2 years out of one of these inflatables, consider yourself lucky.
In most cases they can be repaired, but probably not professionally repaired by us. More commonly they are patched to get a little extra life out of them. If you are in Colorado, there is a small chance that we may be able to do the repair for a reasonable price. We provide free estimates if you send us pictures of the damaged area, and a picture of the inflatable as a whole so that we can get a good idea of what model of inflatable you bought. If you are not in Colorado, it is likely that the shipping and repair costs together will be prohibitively expensive. Read on for information about patching these inflatables.
More commonly, use Tear-Aid Type A repair patches to keep residential-grade inflatables going. As these inflatables age, the seams start to blow out, especially on waterslides. A Type A patch kit will keep things going until the next seam blows. These patches are durable, waterproof, and semi-permanent. Although the patching material is clear and thin, it is stronger than most residential-grade inflatables, so once you apply a patch, that area is pretty much permanently repaired. The patches are easy to apply, and the repair kits come with everything you need to patch the inflatable yourself.
Do keep in mind that these residential-grade inflatables are not built to last, despite marketing materials that may exaggerate their durability. Most of the residential-grade inflatables that we repair are 1 to 3 years old, and the most common problem is a torn seam. Repairs and repair kits can help you get more life out of them, but you will have to throw this thing away some day. We're glad to help where we can, but if you find yourself ordering a lot of patch kits, it's probably time to let the old inflatable go, even if it doesn't seem that old.
