Hand scrubbing with specialized detergent
Tiger stripes, those dark vertical stripes that appear on aluminum rain gutters and other areas of the home where water and debris collect and run down the house. Customers sometimes call us about these dark stripes that will not wash off. The first assumption is that the paint has gone bad, this is usually not the case with aluminum gutters. If these lines appear on a painted surface they can be scrubbed off or re painted.
Naturally, pollution and dirt build up on the top lip of the gutter. When moisture combines with these pollutants, it streams down the face of the gutter. Future precipitation will continuously follow the same path. Over time, the buildup becomes alternating light and dark stripes
During a normal house wash these marks may lighten depending on how discolored the gutters are, for heavily discolored gutters a more thorough scrubbing is usually necessary with a degreasing solution that needs to be hand applied and scrubbed with an extendable brush. This service is not included in our $249 house wash rate due to the increased labor, time, and special cleaning solution. This service is an add on to house washes depending on what the customer's expectation is for the end result, the service ranges from $200 for most townhouses up to $350 for larger single family homes.
