UPDATE: I emailed their office regarding my complaint and they responded me within a day. The customer service was good. They admitted their mistake and provided a solution we both agreed.
I really have mixed feelings.
On the positive side: I emailed Gutter Force for a leaky gutter repair. The communication was easy. The repairing work was scheduled within a week. On the day of repairing, the technician called me to confirm the appointment in advance. He was courteous and even willing to stay longer in order to clean the gutter and check any potential clogged downspouts. He also explained to me what was causing the leak and made recommendations.
However, during the work, I noticed that the technician didn’t use an long extension ladder to climb from ground. Instead, he put another ladder on the roof of my porch. I saw the ladder didn’t have a rubber feet at bottom so it was the metal part touching my 1-year old asphalt shingle. Unfortunately it was late and dark when he finished the repair. Next day, I had a chance to take a closer look and then discovered multiple holes on the roof. I am so disappointed as this mistake should have been totally avoided.
I would not recommend this company.
