Expert work. Quick turn-around. Have always trusted H&H with all my different trucks and the add-ons I wanted.
Jason at the Pelham location was great. After installation of a bed cover was done, we noticed some parts were removed but not put back in place. He went out of his way to fix the issue. Also some end caps were cracked during the installation and he is getting replacement parts for me at no charge. Will definitely go back to them the next time I'm looking to add some updates to my truck.
Great experience! Got me in at my booked time. Said it would take an hour, they were done is 40 minutes. Friendly and even showed me photos of the install. Highly recommend for bike hitch install.
I have been a customer of H&H for years and have always been given the VIP treatment. Staff are friendly, helpful and professional. Quality products and quality service. Go see them today, you'll be better off.
I must say I hate having to deal with things to do with the truck, however the sweetest gentleman was very attentive and not only put on the hitch, but put on the lift and found a needed screw, as well as he took the time to show me all the necessary steps to be successful. Great service, nice people, check them out for sure.
The staff is friendly and helpful. They went out of their way to make sure I got a warranty part replaced. Their communication is professional and they completed the work in a timely manner and it looks wonderful! Thanks!
Great service. Super quick install.
Love the new look
Eric was a pleasure to work with on my LEER top! Capable service guys installed my top and it looks great. Thank you!
Great experience!
Tyler and his team have done a couple different jobs for me this year on two different trucks. The quality of work was outstanding.
Great service
Brian and his employees did an outstanding job!! upgrading my 2013 Ford F150 truck. His customer support,patience and fair pricing was really appreciated. I felt taken cared of & the result was excatly what I needed.
It’s great service here an good products to Choose from plus a great atmosphere.
The HH sales and install team were through the whole process of ordering, receiving and storage of my LEER topper and Decked slide out. I’m already looking at additional upgrades to my truck because of my confidence in their professionalism
Fast! My order was ready, and installed in less than 24hrs! (Would have been sooner but I had to wait till next day) Staff was very friendly, will definitely be back!
Luke went out his way to make sure we had enough space for the delivery for our new shed!! Thanks Luke! You're awesome!!!!!!!
I had a problem with a tonneau cover almost blowing off. I patched it as best I could and visited H & H in Muscle Shoals to see if they could fix it even though it had been installed at a different H & H store. Rusty was kind enough to fix it easily. Highly recommend this individual.
Had the pool parts we needed and a lot of other things!
Excellent service. Highly recommend!!
It was a good experience, everything went as we told, although a little delayed. The waiting room was however not comfortable and could have used a good deep cleaning and more comfortable seating. The bed liner we purchased was great but the store needs a little TLC!
Super great service No complaints at all
The men at H&M’s H were outstanding With great customer service. I will go back to the Andalusia H&H for any needs for my truck. Thank you for a great experience.
Love my new bed cover! It looks amazing and will provide much needed protection for items I chose to put in the truck bed. Everyone was uber friendly! The bedliner I chose was reasonably priced and installation took less than 30 minutes. I will be spending more $$ there when I need some other truck accessories! Before and after pics of my truck bed.
