WINDOW REPLACEMENT COST · MARTIN COUNTY, FL

What a window replacement really costs in Martin County.

Martin County is affluent, coastal, and full of HOA-governed communities on Florida's Treasure Coast, from Stuart to Jensen Beach, Hobe Sound, and Palm City. It is not in the High-Velocity Hurricane Zone, but it sits in the Wind-Borne Debris Region with a high design wind speed, and a strict architectural-review layer often shapes home projects here as much as price does.

Typical window replacement cost ranges in Martin County

These are planning ranges for a typical home replacing about 14 windows. They are a starting point for asking better questions, not a quote or an appraisal, and your actual price depends on the size, materials, access, and condition of your specific home.

Vinyl replacement: roughly $11,500 to $16,500. The most common and budget-friendly option for a straightforward replacement.
Composite or fiberglass: roughly $15,500 to $22,500. More durable and dimensionally stable than vinyl, at a higher price.
Wood clad: roughly $20,000 to $29,000. A premium look with an exterior cladding for weather protection.
Impact or hurricane-rated: roughly $23,500 to $34,000. Reinforced glass and frames for high-wind and wind-borne-debris regions.

Not HVHZ, but a high design wind speed and a strict HOA layer

Martin County follows the standard Florida Building Code with local amendments and sits in the Wind-Borne Debris Region, so exterior work must meet the county's wind requirements for the site's design wind speed. On top of the code, many Martin County homes sit in HOA communities where an architectural review board can weigh in on visible exterior work, including where outdoor equipment is placed and how it is screened.

Waterfront and barrier-island parcels near Stuart, Jensen Beach, and Sewall's Point carry the county's highest wind exposure and the most salt-air corrosion, which shortens the life of outdoor equipment.
HOA architectural review can add weeks to a project timeline, so confirm approval requirements before scheduling work.
Permits are pulled through the county or the relevant city building department depending on the parcel.

An affluent, detail-oriented market

Martin County's affluent, coastal character means homeowners here tend to expect itemized, well-documented proposals and are quick to notice a vague one. A complete quote should spell out the scope, the equipment, and the warranty rather than leaning on a single lump-sum number.

What a fair window replacement proposal should spell out

The window brand, series, frame material, and glass package per opening
Energy performance numbers (U-factor and SHGC) for the climate
Whether it is a full-frame replacement or an insert, and why
Any wind or impact rating required for your location, stated explicitly
Installation method, trim and finish work, and the warranty terms

Martin County cities and what tends to differ locally

Stuart: A mix of an older, walkable downtown with mid-century homes and newer waterfront construction along the St. Lucie River. Waterfront parcels face the county's highest wind exposure and salt air.
Jensen Beach: Coastal exposure on Hutchinson Island alongside inland mainland neighborhoods, with barrier-island properties facing higher wind and salt-air demands than mainland homes nearby.
Hobe Sound: Home to several large, tightly governed HOA communities where architectural review can add weeks to a project schedule homeowners should plan for.
Palm City: A newer, planned-community-heavy market west of Stuart built largely under HOA guidelines, with fewer older homes than the county's coastal cities.
Sewall's Point: A small, high-value peninsula community between the forks of the St. Lucie River, where nearly every property is waterfront-adjacent and wind exposure runs at the top of the county's range.

Frequently asked questions

What is the difference between an insert and a full-frame window?

An insert fits inside the existing frame and is faster and cheaper, but only works if the existing frame is sound. A full-frame replacement removes everything down to the opening and is the right call when frames are damaged or you are changing the window size. The proposal should say which you are getting.

Do I need impact windows?

It depends on your location. High-wind and wind-borne-debris regions may require impact-rated windows or an approved shutter system. Your proposal should state the specific rating your address requires rather than leaving it vague.

Why is one window quote so much cheaper?

Usually it is a different frame material, glass package, or installation method, or it leaves out trim and finish work. Compare the spec per opening, not just the total.
