“DB Builders is one of the best construction companies I have ever worked with. First of all, Doug and his guys are some of the nicest, friendliest guys you will ever meet. Just having them around the job sight was a lot of fun. But the most important thing is their work. DB builders know how to build, and they know how to build right. I would stand their work against another construction company in Humboldt County any day of the week. They are not only great at what they do, but they are also super affordable.
