Grading Contractor Northern Virginia is Nova Construction Pro. Many homes built in Northern Virginia were poorly graded by the contractors that built these homes. Today, if a contractor builds a new home, it will require the seal by a land surveyor, architect, or licensed civil engineer licensed in Virginia before a building permit will be issued. Your new home may have been graded properly, but with the backfilled, dirt may have settled, leaving the grading plan ineffective. When soil settles around the foundation, water will be then pushed back and can lead to water infiltration into your home. Simple solution for this problem is simply add more soil and create a grade that will move the water away from your home.
