Customer Reviews

In this day and age, it's difficult to find a business that treats it's customers the way I was treated at Cap World in Gaithersburg, Maryland. I thought I had stepped back in time, to the 70's. Sam is the manager at Cap World and he and his team did everything perfectly and professionally. I ordered a LEER cap for my pickup truck, it arrived, an appointment was set, I arrived half an hour early, but they still got me in an out very quickly. No fuss, no muss. The entire process was quick and painless, just the way it should have been. So, if you need an accessory for your pickup truck or SUV, don't waste your time, just call Cap World in Gaithersburg, MD, and talk to Sam the man. Abbas T.
Helpful service, quality work, and very competitive pricing. Quentin Compson
Sergio helped me choose the cap that best met my needs, gave me a good price, and provided excellent customer service. Installation was included and well done. Product high quality. No upsell pressure. Highly recommend this shop. Mark S.
I dealt with Sergio here, and can't say enough good things about him. He even got back to me on his day off and organized the installation of of my Bakflip tonneau cover. It was professionally installed and was quick. I would recommend Sergio and this company to anyone I know and don't know for that matter. David T.
