Exterior Grading and Downspout Drainage
Many wet crawl spaces start outside. We regrade soil so it slopes away from the foundation, extend downspouts and fix low spots, so roof water and rain do not collect where they can reach the crawl space.

About exterior grading and downspout drainage
Does outside work replace interior drainage?
Sometimes it solves the problem on its own. When water still enters, interior drainage and a pump finish the job.
How far should downspouts go?
Often several feet or more away from the foundation, depending on the slope. We plan the discharge for your yard.
