The owner, Vincent Hubner, impressed me with his knowledge AND honesty. I had him come to my house for an estimate on roof cleaning for the moss stains and live moss. Since he also does pressure washing of siding, I asked him for an estimate of the latter and he touched and rubbed the siding with his hand and said it was old and the white color may flake off from the pressure washing; although it would be clean, it could look worse. He could have taken the $$ and ran, but his honesty precluded that. When his crew came for the roof, they were pleasant, hard working, cleaned up afterwards. responsive etc. IN ADDITION TO DOING A GREAT JOB!! I highly recommend this company with no reservations whatsoever.
