Real Client Story â A Brighter, Stronger Home
Our clients reached out to us after noticing a persistent haze in several roomsâespecially where the morning sun hit. Their existing double-pane windows had failed seals, allowing moisture and air infiltration, making the glass appear cloudy and the rooms dim.
We replaced their outdated units with ProVia Endure vinyl windows, featuring argon gas fills and double Low-E coatings. Not only is their view clearer than ever, but their HVAC system runs less frequentlyâespecially on humid days. Near the coast, where salty air and high UV exposure are constant, choosing high-performance windows isnât a luxuryâitâs a necessity.

đĄď¸ In Wilmingtonâs ENERGY STAR Climate Zone = Argon + Low-E Glass is a Must
Wilmington is located in the Southern ENERGY STARÂŽ Climate Zone, which means your windows need to handle humid summers and mild, fluctuating winters. Thatâs why high-performance glass is criticalânot optional.
Hereâs what makes the difference:
đ§ Argon Gas Fills â Acts as an invisible insulator between panes, reducing heat transfer and improving energy efficiency.
âď¸ Low-E Glass Coatings â Reflects infrared and UV rays to keep your home cooler and protect your furniture from fading.
đŞ Insulated Window Frames â Helps reduce indoor condensation, improves comfort, and lowers energy bills.
â ď¸ Beware of code-minimum windows: Just because a window meets local building code doesnât mean it performs well in Wilmingtonâs coastal climate. Thatâs why every window we install is selected to exceed ENERGY STAR standards for coastal NC homes.

"What a gem of a home improvement company. They do it all (roofing, trim coil and gutters, in my case), they do it well and the job is on time. Best of all, they patiently answer all questions and if they don't know the answer, they find out for you. I highly recommend them."
Whatâs the best window type for homes near the Wilmington coast?
We recommend vinyl or fiberglass windows with reinforced frames and double Low-E glass. These materials resist salt air corrosion and help reduce heat transfer in humid summers.
Do I need a permit to replace windows in Wilmington, NC?
For most residential replacement windows (like-for-like size), a permit isnât required. However, if youâre enlarging openings or replacing windows in a flood zone, a permit may be necessary. We handle all code and permitting issues for you.
Are ProVia windows good for Wilmingtonâs hurricane zone?
Yes. ProVia offers impact-rated windows and DP-rated frames that meet or exceed coastal NC building codes. Their airtight seals and thicker vinyl extrusions are especially good for homes within a few miles of the ocean.
How much does window replacement cost in Wilmington?
Window replacement in Wilmington ranges from $1,200â$1,500+ per window depending on material, size, and glass package. We offer financing and free estimates so you can plan without pressure. The reason the ranges for windows are so large is because there are so many options and styles.
How do I know if I need new Windows?
If you see fog between panes, feel drafts, or have difficulty opening windows, itâs time to consider replacement. Blown seals are common in older beach-area homes and can lead to mold and energy waste.
