FAQ
Common Questions from Prince George's County Homeowners
How long does window replacement take?
Most window replacement projects are completed in a single day. A full-house replacement of 15–20 windows typically takes one to two days depending on window styles and complexity. We protect your home throughout and complete a full cleanup before we leave.
Do I need a permit for window or siding work in Prince George's County?
Permit requirements vary by scope. Many like-for-like window replacements do not require a permit in Prince George's County, while structural changes or full siding replacement may. We handle all permit research and application as part of our service at no extra hassle to you.
What is the difference between vinyl and James Hardie siding?
Vinyl siding is lighter, lower cost, and maintenance-free. James Hardie fiber cement siding is a larger investment but offers superior fire resistance, impact resistance, and a wood-like appearance with a factory-baked ColorPlus finish that holds up exceptionally well in Maryland's climate.
Will new windows lower my energy bills?
Yes. Our Energy Star certified windows with Low-E glass and argon fill significantly reduce heat transfer. Most homeowners in Prince George's County report noticeable reductions in drafts and HVAC run time after replacing older or worn windows.
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 when you schedule your free in-home estimate.
