Step 1 of 7
How many windows are you thinking about replacing?
Include every window you'd want priced. You can adjust this later — it's just the starting point for your estimate.
Most Coastal Carolina homes have 12–22 windows. Not sure yet? Start with 10 and adjust any time.
Step 2 of 7
Do you have a window material in mind?
Material is one of the single biggest cost drivers. "Not sure yet" is a totally valid answer — we'll show you the full range.
Step 3 of 7
Do you need impact-rated windows?
Impact windows are engineered to withstand hurricane-force winds and flying debris. In many Coastal Carolina areas they may be required by code — and they can reduce your insurance premiums while eliminating the need for storm shutters.
Step 4 of 7
What type of home are we working on?
Multi-story homes and waterfront or high-wind-exposure locations can affect both labor requirements and product recommendations.
Step 5 of 7
What do you know about your current windows and home condition?
Older homes and coastal properties often have wood rot or soft framing around window openings. Knowing this upfront helps us build a more honest estimate — and means no surprises on install day.
Step 6 of 7
Are you adding any doors to this project?
Many homeowners upgrade doors at the same time as windows — it simplifies scheduling. Set any door type to 0 if it doesn't apply.

📊 Key factors driving your estimate
Window replacement costs in Coastal Carolina can range from $5,000 for a small partial job to well over $40,000 for a full whole-home impact project. Here's what actually moves the number:
Material: Vinyl is the most affordable and most popular. Fiberglass performs better in coastal humidity and salt air but costs more. Wood carries the highest price tag and requires more upkeep — it's rarely recommended for oceanfront homes.
Impact vs. standard glass: Impact-rated windows can add 45–60% to window cost. However, many homeowners recoup part of that through reduced insurance premiums and by eliminating the need for hurricane shutters.
Project size: Whole-home replacements typically cost less per window than replacing one or two at a time because installation labor and mobilization are spread across the full project.
Installation conditions: Older homes in coastal areas often have wood rot or soft framing around window openings. Finding and fixing that during installation adds cost — but it has to be done correctly or your new windows won't seal or hold properly.
Product tier within each material: Even within vinyl, there are entry-level, mid-range, and premium product lines with meaningfully different performance specs and price points.
The best way to get a firm number is a free in-home assessment. That's where we measure every opening, check for hidden issues, and give you a real price — not a range.
Window product cost (materials and hardware)
Professional installation labor
Standard interior and exterior trim and casing
Haul-away and disposal of old windows
Caulking and weather sealing at install
Manufacturer product warranty
Wallaby Windows installation workmanship warranty
Free 23-month post-installation inspection
These are the most common reasons a final quote comes in higher than a ballpark estimate:
Wood rot or structural damage discovered around the window frame during removal — common in older coastal homes and almost always needs to be repaired for the new window to seal properly
Non-standard or custom window sizes that can't be filled with a stock product and require a special order
Upper-floor or difficult-access windows that require scaffolding, extended ladders, or more setup time
Interior finish upgrades — custom trim profiles, jamb extensions, or wrapping that go beyond standard casing
Permit fees depending on your municipality or HOA requirements
Material or glass package upgrades — obscure glass, specialty colors, or a higher-performance SHGC/U-factor package
Our free assessment is specifically designed to catch all of these upfront, so there are no surprises on install day.
