Extensions or underground drainage that carry roof runoff away from foundations, crawl spaces, and low areas.
Exterior water problems are best approached by identifying where the water comes from, how it moves across the property, where it collects, and what happens during heavy rain. Ask the provider how the proposed work addresses the water path and whether grading, drains, downspouts, sump equipment, or waterproofing need to be coordinated. Before contacting a provider, note the current downspout outlets, where runoff goes, nearby pooling or erosion, and whether underground piping already exists.
