In short: replacing a window in Boca Raton means removing the old unit, setting an impact-rated window made for that opening, anchoring and sealing it, finishing the stucco and trim, and passing a permit inspection. As an estimate, a standard window runs about $850–$2,100 installed, and picture or custom-shape windows about $2,000–$4,500.
What is coming out of Boca homes
East of I-95, neighborhoods such as Boca Square, Boca Villas, Camino Gardens and Winfield Park were built largely in the 1960s and 1970s, and many still have mill-finish aluminum single-hungs or horizontal rollers with single-pane glass. Plenty have a Florida room closed in with jalousie louvers that never seal. West of the turnpike, the country club communities of the 1980s and 1990s were fitted with builder-grade frames whose insulated glass has started to fog between the panes. Then there are the Mediterranean-style homes with arched tops and eyebrow windows, where the shape matters as much as the protection.
Different houses, same problems: glass that does nothing against flying debris, frames that sweat through the summer, and locks and balances nobody stocks any more.
How we replace a window, start to finish
- Measure each opening. We take every opening's width and height in three places, because block openings in older homes are rarely square, and units are built to those numbers once the permit is filed.
- One opening at a time. A single window comes out, the opening is cleaned and checked, and the new unit goes in before the next one is touched. No room is left open overnight.
- Anchor to the approval. Fasteners go into the block or framing at the spacing the Florida Product Approval specifies for that size and pressure. That detail is what the inspector checks.
- Seal and finish. The frame is sealed against wind-driven rain, the exterior stucco return is patched and painted to match, and interior sills and trim are reset.
- Close the permit. Product labels stay on the glass until the final inspection is signed, then they come off and the old windows leave with the crew.
Choosing frames, glass and style
White and bronze aluminum frames suit most Boca homes and handle large spans well. Vinyl frames insulate a little better on bedroom and bathroom sizes. Almost every job here uses laminated impact glass with a Low-E coating, which keeps west-facing rooms cooler in the late afternoon and slows fading on wood floors. Gray or bronze tints are popular in communities that allow them, and bathrooms can take obscure glass.
You can change a window's style as part of the replacement. A pair of narrow single-hungs can become one picture window with operable sides, or a horizontal roller can become a casement that opens fully. Where a change means altering the opening, we say so up front because it affects the price and the permit.
Arched, round-top and historic openings
Boca has more arched and custom-shaped openings than most Florida cities, a legacy of the Mizner-era Mediterranean Revival look. Every arch, half-round and eyebrow is templated on site and built as a custom impact unit, not trimmed down from a stock rectangle. In the Old Floresta neighborhood and other designated historic properties, exterior changes may need a review before a permit is issued, so we check that before anything is ordered.
Condos and association homes
Many Boca condominium declarations make windows and sliders the owner's job while the association decides what they look like. Before ordering, we get the board's specification for frame color and tint, and we prepare the product approvals, insurance certificate and scope letter the manager will ask for. Above 30 feet off the ground the code allows small-missile glass, but the wind pressure is higher, so the design pressure rating is checked floor by floor.

Window replacement questions
Does a replacement window in Boca Raton have to be impact-rated?
A replaced window has to meet the current Florida Building Code for where the house sits, and across Boca that means protection against wind-borne debris: either impact glass or an approved shutter for that opening. Nearly everyone we measure picks impact glass so nothing has to be put up before a storm.
Can the work be split over two seasons?
It can. Plenty of owners start with the east-facing side or the street front and finish the following year. Bear in mind that the full insurance credit for opening protection normally needs every opening covered, so check with your agent before you phase.
Will the inside of the house get messy?
There is some dust where an old frame is cut free, and we sheet the floor and furniture near each opening. Interior returns and sills are put back the same day, and the crew vacuums before moving to the next room.
What if an opening turns out to be rotten or out of square?
Rotted wood bucks are cut out and replaced, and out-of-square block openings are shimmed and anchored to the approval's spacing. If we find either during the measure, it is priced in the quote instead of appearing as an extra later.
