"Pretty good, but I have noticed a lot of soft spots in the flooring and felt that those spots should have been fixed before the flooring was installed. I don’t know what is going to happen over the next few months or years, are these spots going to break thru?"

"Best contractor one could find?Sean Carlstrom and Jerry Williams did all work, themselves, except for drywall, spackling, and granite fabrication and installation. The construction industry recognizes three grades of quality, Good, Better, and Best. Carlstrom does only ?Best.?
I got three estimates. The first was ?Good? in that the contractor wanted to install his standard kitchen on a cost plus basis. The second was ?Better? in that the contractor wanted to do all work, himself, in accordance with our wishes but seemed to lack a full understanding of the scope of the job. Only estimator Jim Sittler and owner Sean Carlstrom were able to grasp the full scope of our project and give us a fair bid for ?Best? quality. They did this with a firm contract.
Carlstrom referred to the plans consistently and never varied. If a question cropped up, they asked and complied with the decision with no sign of resistance or anxiety.
