I decided to get my gutters cleaned last year because I noticed that during heavy rain falls that water was not coming down a down pipe on a specific side of the house and instead was over flowing over the gutters. So I called Holland to have someone come over to do the gutter cleaning. I wasn't home while the job was done so I just trusted them. But after the job was supposed to be done I still noticed the same problem after heavy rain fall, so this year instead of going through Holland again I called up another company. This company came over and took "before" pictures of my roof with my own phone and it clearly showed that nothing was done, the drain was covered with moss! this new company cleaned it up and took "after" pictures on my phone again to show the work performed. and also pored water down the drain to show that it's working properly. thanks for the rip off Holland
