Although we would prefer to have our team meet you, no, we don’t require anyone to be present at the time of service. Our team can take care of all your needs from the exterior of home. If you are having interior windows done, many clients will leave a door code or hide a key for our team if they will not be home.
Soft washing is a safe alternative to pressure washing that is fairly new however, tested and trusted by the real pros. Soft Washing uses less water than pressure washing, won’t damage your home with high pressure, and addresses organic growth at the root for longer lasting results.
Dead moss may still be present on your roof when our crew leaves. This moss is rooted into your shingles and at this time would only be able to be removed with damaging force. The fabulous thing about soft washing is, all this moss will shrivel up and fall off on its own over the course of one to six months depending on the climate.
This ultimately depends on your home’s specific location but, we can guarantee at least two years. Some clients in that live in sunny farmlands may not need to wash their roof again for five years!
Make sure the areas where our team will be working is free of items such as patio furniture and small potted plants. If we are cleaning interior windows, we ask for all delicate items to be removed from the window sills. If you are having your exterior windows cleaned, we ask that you remove all screens before our arrival so our crew has access to exterior glass.
This depends on what is on your quote and what you may have requested. We do not clean interior window frames but will clean tracks and sills if requested. Exterior window frames are cleaned with a siding soft wash service.
