Do you have a very special older air gun (airgun) that needs to be repaired or resealed?  If so, you probably want to give me a call--630.232-9518, Harold Hajek.  I will likely be able to reseal your air gun (airgun) and get your gun back to better working condition than when it was new.  I can fix or reseal any air gun (airgun) but I specialize in the Crosman air gun repair / reseal, Sheridan air gun repair reseal and Benjamin air gun repair / reseal.  I am a Factory Authorized Warranty service technician and have been doing this for a very long time for people all over the world!


I owned a Sporting Goods store in Geneva Illinois for many decades and have been repairing air guns in my store and at my home in Geneva Illinois now for over 40 years.  I have quite an inventory of parts and all the right tools to get the job done right.  I also run a booth at the DuPage County Illinois gun show and can probably find replacement for any hard to find parts that may be damaged or missing.  I usually charge around $50 for a basic resealing job but will have to quote anything else separately.


DO NOT attempt to make repairs yourself unless you are thoroughly familiar with air gun (airgun) repair. It is very dangerous to take a gun apart yourself.  In many cases, the mainspring in spring-piston air guns is under considerable pressure even when the gun is not cocked. Releasing the spring without proper training and tools can cause cause serious injury.  There are also special tools necessary to disassemble the gun.  Repairs (or attempts) made by an amateur on a newer gun will void the manufacturer's warranty.


For service on your older air gun (airgun), or Factory Authorized Warranty Service on your newer Sheridan, Benjamin or Crossman air gun (airgun), give us a call:
