FAQ
Common Questions from Washington, DC Homeowners
Do I need a permit to replace windows or siding in DC?
Yes, most exterior work in Washington, DC requires a permit through the Department of Consumer and Regulatory Affairs (DCRA). In some cases a building permit is required; in historic districts, review by the Historic Preservation Office (HPO) may also be needed. We handle all permit research and applications as part of our service.
Can I replace windows in a DC historic district?
Yes, in many cases — but the process requires HPO approval and the replacement windows must meet specific guidelines, often matching the original profile, divided light pattern, and material appearance. We have experience with historic district submissions in DC and can help guide you through the process with the right product selections.
How long does window replacement take in DC?
Most window replacement projects are completed in a single day, even in urban DC settings. A full-house replacement of 15–20 windows typically takes one to two days. We are experienced working in rowhouses, condos, and detached homes throughout the District.
Is James Hardie siding approved in DC historic districts?
James Hardie fiber cement siding is often approved in DC historic districts because it closely replicates the look of traditional wood siding while offering superior durability. Approval depends on the specific historic district, the existing materials, and the proposed profile. We can help assess your property and navigate the HPO review process.
Do you offer financing?
Yes. We offer flexible financing options to make window and siding replacement accessible for most budgets. Ask about current promotional rates and monthly payment plans when you schedule your free in-home estimate.
