Words from Our Clients


The people behind Gasket Masters are awesome. They were professional, knowledgeable, and honest. They replaced my head gasket on my 2010 Prius. They came to my house and in about 4 hours the car was running in my garage. If every automobile repair shop functioned as these guys do then people would not feel so much distrust with repair shops and mechanics.

This review is for Allen, Gasket Masters and the hybrid car clinic in Roanoke, TX. Very efficient, professional and EXTREMELY knowledgeable about Toyota Prius engines. Stayed late until I arrived in town. Worked on my vehicle even though he was very sick. Replaced head gasket and number 1 rod in very fast manner. Restored my engine to like new. Very affordable would HIGHLY recommend Allen from Hybrid Car clinic, Gasket Masters in Roanoke, TX. I am very grateful for Allen and his services. Thank you.

I’ve watched the Gasket Master YouTube channel, great information and content. Their channel is the reason why I chose them to replace the head gasket on my gen 3 2011 Prius. They truly are the head gasket specialists. Amazing price, quick service, and very professional.

James L.

★★★★★

Very happy with the repairs to my 2012 Prius. It was clear the head gasket was blown and my research led me to Gasket Masters. A shop in Berkeley quoted me $5000 for the repair but Gasket Masters quoted $2150 out the door! There was availability immediately so I planned my arrival for 8am and, as promised, the car was ready at 2pm. Very happy with the service and the repair. My car is running great now!

★★★★★

I had a visit from the mobile unit last Friday to replace the engine in my Prius 3. Scheduling was quick, the guys arrived as arranged and the job was finished in two hours. It was a quick, affordable and no hassle experience. I was back on the road that day satisfied that Prius experts had taken care of my ride. I highly recommend!
