Older homes, four historic districts, and a lot of trees over the concrete.
Whittier has four locally designated historic districts, Hadley-Greenleaf, Central Park, College Hills and Earlham, and the houses in them do not match. Late Victorians with wood trim and bay windows sit near craftsman porches and 1920s Spanish Revival with stucco walls and clay tile. One street can need three different approaches.
The city has also been a designated Tree City since 1984, which is lovely to live with and hard on concrete.
Leaf litter sitting wet on a walkway leaves tannin stains that look like the concrete itself has darkened. They come out, but not with a hose and not by waiting.
On the houses, the rule is the age of the surface. Wood trim and bay windows get soft washing and a careful rinse. Stucco and tile get low pressure and more solution. Nothing here gets the pressure a modern slab can take.
Tell us when you call. It changes what we bring and how we work, and it is a good reason to walk the property together before anything gets wet.
Older properties also tend to have old paint, and old paint on wood does not always survive a wash it should have survived. Where we have any doubt we test a small area out of sight first and show you the result before going on.
