Comment: There was a mix up in my address and phone number, so the technician was late, and I did not see him. I have had previous Dalworth technicians in my home before, and their appearance was fine, so I'll just go with that impression for Question 3.
Both the office personnel and the technician were very polite and apologetic for the delay, and offered to dry my bedroom carpet at no additional cost, which I definitely appreciated.
The tile and the grout downstairs look amazing, and I'm so glad I decided at the last minute to add the sealer. I ordered the least expensive carpet cleaning, and the carpet in my newly inherited home is both old and dirty, so those results were less than I had hoped, but it does smell better, at least.
