I was in the market for a concrete slab foundation for a small vinyl shed. I had spent several weeks getting verbal estimates. The estimates ranged in price from $500 - $1,100. After making a couple of verbal agreements and having contractors not follow-up or show-up to do the agreed work., I was becoming frustrated. A co-worker recommended Bob Davidson of Concrete Works. I called Bob and discussed the project. To save on expenses Bob recommended a block paver foundation. He also said he and his crew could assemble the shed (this was before he saw the shed). He called early the next morning and said he could come by for a site inspection and possibly do the job the same day. I met him before work to show him where I wanted to put the shed and the two large boxes in my garage which contained the unassembled shed. His crew was finishing up another job and would begin my job later that day. Later in the afternoon Bob called to let me know he had looked at the assembly instructions for the shed. He advised it was much more detailed than he thought (I expected this) and they wouldn't be able to assemble it the same day. He would also need to increase the cost to pay his guys for another day. I felt his original estimate was on the low side for the work I thought would be involved in assembling the shed. Therefore, I was willing to pay additional. I also appreciated that he discussed this with me prior to beginning the assembly of the shed. They came back the next day assembled the shed, discarded the boxes, and cleaned up their work site. I couldn't be more pleased with the work done by Concrete Works. Bob Davidson was professional, prompt, courteous, and reasonably priced. I would not hesitate to use him again.
