If you have not broken something yet you aren't trying hard enough. With that said here are some resources to help get you back on the water.
Kite, Wing, and Windsurf Sail Repair.
If you have ripped the material but do not need any bladder or valve work these two lofts do first-class work and actually have some really quick turnaround times. Always call before heading down and please never bring a wet or sandy item to a sail loft. Lofts are notoriously clean and dirty gear is highly frowned upon.

If you have more serious issues you have two options. One is the SF Wing Foil Academy (located in San Rafael) or you can send it by mail to Airtime Kite. Joshua Waldman of SF Wing Foil Academy offers professional wing and kite repair as well as bladder and carbon fiber board repairs locally. SF Wing Foil Academy can also meet you at Crissy Field. Text for quotes on repairs to Joshua 415-350-5524.
While it's not inexpensive to use Airtime we can vouch for their quality work and reasonable turnaround times. With that said you will still need to UPS your gear to Hood River (or Fort Lauderdale) and then have it sent back you. The process starts by filling out a ticket on the Airtime website to ensure the proper parts are in place and to get an estimate of the cost.
If you are not sure if your bladder is leaking or your valve is failing then check out this trick. First, fill a spray bottle with water and a few drops of dish soap. You do not need to add a lot. Once your wing or kite is inflated then spray all over the wing looking for little bubbles emerging from any suspect areas. If you are more of a do-it-yourself type small holes in the bladder can be relatively easy to fix. The hard part can be getting access to the spot you need to work on. Some brands can be notoriously difficult to work with. Valve replacements are also doable but a degree of difficulty is higher for sure. You can get all the parts you need from Pro-kitesurf wing repair kits and replacement valve parts.
Joshua Waldman also does ding repair on fiberglass, carbon, or composite boards in Marin County. Text for quotes on repairs to Josh 415-350-5524. He may even be able to meet you at Crissy Field for pick up or drop off.
