I can't comment on the quality of their work as I feel they didn't do any work, yet billed me twice the aggred-on amount. Mysteriously, the agreed-upon fee was doubled with many add-ons and then was graciously cut back to the original amount to make things better. I was told they cleaned 6 gutters on my house -- there are only 4. My landscaper checked the work two weeks later, said it wasn't done and re-did it for me. I would not recommend this firm to anyone. If you feel you have to use them, get a written contract and be present when they do the work.
