Bryan recently cleaned my gutters and did a great job. There is a difficult area, about a quarter of the total guttering, that is partially covered by a pergola. This has been a problem getting blocked and causing over flows. Two previous people failed to clean it properly. Bryan was able to get all the growth and dirt out. I strongly recommend Gutter-Vac Knox and Bryan for an honest job, great service, quality workmanship, and good value.
