Testimonials

Gia and the team at TBD saved the day. I called and explained my situation and by the time i arrived they had a plan in mind. I followed their instructions and it worked out perfectly and saved me a bunch of money! Recommend them highly.

I needed an insulated jacket for my sprinkler valves. All I could find online was cheap quality and nothing 55” long.A trip to Backflow Depot in Rocklin proved to be a dream come true. I first spoke with Kenzie who was quite knowledgeable and helpful. Then the sales president came out to greet me and gave his ideas. And then the guy who Actually makes them (Manny) came over to explain that my measurements would need to be adjusted in order for the jacket to fit. Thank God! Was he ever right. He added a few inches to the length and a couple inches to the height, allowing for the perfect fit.Manny then got to work and had my jacket very Professionally completed within an hour! Exceptional craftsmanship and high Quality materials. So good, it may outlive me! I cannot praise these guys and girl enough. And the price was unbelievably good. Thank you All. 👍
