What's Your Home Made Of?

Have you ever sat down and thought, “What’s the quality of the materials in my home?”. Probably not, and that’s where most homeowners go wrong; the materials that your home is built with can directly affect maintenance cost, property value, and overall sustainability.

At DBS, we’re here to help you choose the right materials for your project, because we want your projects to be worth the quality work that you invest in it. Visit our design center, or contact one of our dedicated support staff for more information on builind materials

The seller, Levi, has a very blunt attitude with people of Hispanic origin. I have gone three times and he has acted like this three times. The last time I sent an email requesting prices and since they don't sell one thing on the list, they didn't give me the price for everything else. I sent him another email asking for the price for everything else. He ignored me and I had to go in person. When I arrived, I bought everything I wanted from another seller. When he arrived, I let him know about my new email and that I no longer needed the prices because I had already bought something. My delivery was scheduled for the next day, but it seems they didn't like me doing that. Without notifying me, they changed my delivery to another day. I wasted the whole day waiting and paid the assistant for nothing. I called that day and they insisted it would be in the afternoon, but they lied. Today I'm going to see if they do the same thing again. I think Hispanic dollars are not welcome there. I won't go back to that place.
(I spoke with the vice president. He offered to improve the vendors' behavior and apologized for this unfortunate incident, a possible accumulation of unrelated events that led me to misinterpret what was happening. He's a great person and a gentleman. Thank you for the call.)

Shawn Delgado is my hero time and time again. He is an excellent problem solver at heart. Whenever you're building anything, there's always going to be hiccups. He's calm cool collected every time and always seems to come up with an idea. He makes my life tremendously easier and I'm super grateful to and for him. Thank you Shawn for all of your efforts over the years!

So….I had a 49 year old classic receiver, that went out elsewhere, the Case went to DBS. I’ve owned it for decades. I watched the pressboard walnut veneered cabinet dissolve over the years. I brought the frame to DBS to replicate and they used Solid American Walnut…….absolute perfection…….need I say more. Those guys are all craftsmen and it would behove you to talk to them if you’re in the market…..Stunning piece!
