They do great quality work. BUT after paying them 1500.00 to modify my Cargo Doors, They damaged the rear Cargo Door wile my Bus was on their LIFT and now refuse to compensate. Jonh the owner makes excuses why his shop is not reponsible so let the world know. I paid about 25,000 for this work and sux to loose a customer like me but it is how Grumpys does his customers I guess. see the before and after. Had Grumpys install 8 side Windows, 2 corner Windows, 8 roof windows, mofify 2 Cargo Doors, install Belly Pans, replace long side Panel, replace Short Side Pane, and much more.

The customer service, attention to detail and quality of parts is unrivaled. At the shop we currently, and will continue to install Grumpys Metal parts.

The quality of the kits manufactured by Grumpys Metal are spot on OE quality! Ive had the pleasure of installing their Bus sunroof conversion and I highly recommend it! John & the staff are true professionals and answered all my questions and shipped the product fast and well packed. 5 stars!

Cant say enough good things about John Alba and his staff… Recently I bought a full ragtop kit from grumpys and it got damaged during shipping… all it took was one phone call and John took care of it all and sent me a whole entire new kit and make sure everything was perfect… Lastly he recommended The pebble sand color cancans top for my bus and once we got it on I couldnt agree more with him..Its perfect better than I couldve ever imagined… Thank you John you guys rockAlbert64.. 21 windowSouth Fla
