Diligent Exterior Remodeling originated from a family-owned and operated window installation company, Diligent Windows and Doors. After years of servicing Maryland, Northern Virginia and D.C. communities, we realized we could provide added value to homeowners by taking care of all their exterior remodeling needs. With the inception of Diligent Exterior Remodeling, we immediately got to work sourcing the most sought-after materials and creating a system that enables our valued clients to customize their ideal home exteriors. Whether you're in the market for roofing replacement, window installation, stunning James Hardie siding, new gutters, or waterproofing, our team of trusted and certified contractors have you covered.
