Northwestern Repair = Excellent work! Excellent people! Jason B.

We’re from Washington state and at an RV park in Missoula when we found transmission fluid leaking from our truck. I called Justin and he was super friendly and sent some guys out to check it out who were also amazingly helpful and friendly. Happened to be a quick fix to get us back on the road!! Danielle S.

Thanks so much for the excellent service and quick response.  We will definitely be in touch whenever the situation arises. Gus at Earth & Wood

Justin has worked on a few diesel pickups for a company I work for.  Top notch work.  Easy to get along with.  Has good connections for hard to find stuff.  Went out of his way to track down random transmission linkage for me once.  Tough to find! I’m always the kind of guy who fixes his own stuff and when something stumps me, it goes to himHighly recommended. Brent L.

Justin can fix anything.  Very trustworthy.  You’re in good hands. Alex K.

Justin has always been just a phone call away.  He is quick and professional.  He has always gotten us back up and running in record time.  Thank you. Colleen V.
