Amazing customer service, absolutely professional, and super reliable. Deanna is very knowledgeable, gives great advice, and is probably the sweetest woman alive.

Considerate and professional. They walked me through every step of the process to perform an oil rust-prevention undercoating to my vehicle. This is my new go-to place for such things.

Absolutely the best service I have personally experienced. The entire undercoating process was explained and was done in 45mins. Couldn't ask for better customer service. I plan to have the service done yearly. Warm and friendly people!

Professional shop. It was easy to schedule the undercoating service, including walking me through the different options available. Undercoating itself was quite thorough. It turns out my skidpad was missing several bolts and they fixed that as well. Will return!

Jr’s Undercoating is the best in the business, bar none. I’ve used them for several trucks in the past and they do an incredible job every time – whether it’s a heavy duty truck, antique or daily driver. They make a point to get the job done right and properly apply the undercoating to all body components/parts/cavities. Compelled to write this review because I recently went to another shop that was closer to my location (Seacoast NH) and I paid more for a subpar job that wore off in under 4 months.

Awesome people and an awesome service. Brought my Silverado 1500 in for an undercoating service. Couldn’t be happier with the work. Deanna and Jr were amazing to deal with. Already have my undercoating appointment scheduled for next year. I recommended Jr’s without reservation.

After calling around to several places and looking for a worthwhile shop to do an undercoating for my Jeep I came across this family owned business, and I’m glad I did. Honesty goes a long way and these people do not fall short from this. Apart from an honest and transparent business, the undercoating done to my Jeep was well thoroughly done. Couldn’t recommended Jr’s undercoating enough. Price wise very reasonable as compared to other overpriced businesses out there. Do not hesitate to consider this business for your undercoating. Beyond pleased.

Got my Tacoma undercoated for the first time and they were awesome at explaining the process. They went above and beyond on accommodating a pickup time for me. I was able to pick up my truck after hours and drop off cash into the drop box. These people trust their customers which is something that you don’t see anymore. Highly highly recommend.

I had an excellent experience at JRs. It was my first time getting undercoating and the staff was very helpful in talking me thru the process and answering all my questions. I appreciated their transparency regarding the age of my vehicle (1999) and the potential that it might not have been a good candidate for undercoating but after seeing it in person they were comfortable to proceed. The attention to detail in undercoating was superb and after the job was complete, they walked me through what they had done and areas to monitor moving forward. Overall a great experience will be back next year.

Great people, the customer service was exceptional. Miss Donna and her husband were wonderful to work with and do quality work. Thanks to Jr’s for the undercoating. If you’re new to the north east as I am, undercoating is needed if you want to keep your vehicle rust free I highly recommend them for the work and will be using them again.

I too have an older SUV from 2011, and needed to preserve my undercarriage due to rust on my recently replaced sub-par frame. Thankfully Colin from Marlboro Nissan highly recommended this business and I proceeded to make an appointment four months out. This was my first initial visit on 2-12-26, and Deanna, & Rodney (son) were all very warm and welcoming. The price was right and the job was very thorough. Rodney applied the creosote underneath and took TLC of my vehicle..... I cannot think of a better way than to protect the life of my investment, and JR's Undercoating deserves more than 5 🤩 stars... They're #1 for a reason with regards to auto maintenance built by their reputation, mission statement, motto, and transparency. I highly recommend them for all your automotive needs no matter how small, because they can handle just about anything you can throw their way. Sincerely, Cat S.
