Roof Cleaning Service
$1,298
They were on time and cleaned the roof and power washed the exterior of the house. They did a good job and cleaned up after themselves. However when they washed down the exterior they failed to close the cover over one of the GFI plugs and when they power washed the wall they shorted out the GFI plug and we had to have an electrician come out to replace it.

These guys were amazing! They came in, cleaned my solar panels and were out without any messing around. They were neat and clean and cleaned up after themselves before they left. Will definitely use them again.

Very professional. Showed up on time and were very concerned about doing their work perfectly and ensuring that my wife was satisfied with the outcome. Will put them on schedule to do this again in 6 months.

Unfortunately, there were several issues from start to finish... 1. Arrival time changed several times (from 9am to 11 am to 10:20 am); when Simon finally arrived, he left for 2 hours, which extended the work by 2 hours; 2. Price changed from $45/screen repair to $55/screen repair when told screens would be black rather than the aluminum-colored expected; 3. Damages including broken window curtain bracket and window blind stuck from being pulled too high; 4. Alerted Cornerstone to the damages immediately and their inappropriate response was that I "was told" about the damages; 5. Follow-up appt. scheduled by Cornerstone for 9 days later; and 6. Call received a week after work completed (2 days prior to follow-up appt.) to discuss and compensate for the damages at the documented estimates that I provided. The work done was satisfactory but there were issues/damages... Informed that Simon is no longer with the company.

We went on Angi Monday AM looking for screen door repair. I got an immediate call from Cornerstone Curb Appeal with a firm quote and scheduled for Wednesday, as Tuesday was July 4. Meticulous Simon showed up on time, and the work is flawless. I expected some upselling and was elated there was none. Highly recommended!
