Fast, Reliable Window Replacement Across Gulf Stream
Window replacement in Gulf Stream moves to a different rhythm than anywhere else in Palm Beach County. The town’s architectural review process adds real calendar time, and the salt air off the Atlantic eats standard aluminum frames faster than most contractors will admit. We know both problems because we work them every month. If you’re staring at fogged glass or a casement that won’t close square, call (813) 320-9346 and we’ll walk you through what Gulf Stream actually requires before you spend a dollar on glass.
Why TruePane Windows & Doors Is Gulf Stream’s Preferred Window Replacement Company
Most window crews in South Florida have never filed a design-review submittal with the Gulf Stream Town Commission. We have, more times than we can count, and we know which frame profiles, muntin patterns, and finish samples get approved on the first pass. That matters because a rejected submittal means another four to six weeks of waiting and another set of architectural drawings you didn’t budget for.
Dale Kessler started TruePane in 2008 after watching too many Palm Beach County homeowners pay twice for the same opening: once for a standard impact window that got rejected, then again for the custom unit that should have been specified in the first place. The Keystone Standard is not a slogan. It means both manufacturer warranty layers get registered in writing with durations stated before our truck leaves your driveway, and the 90-Day Done Right Promise means if something is out of true, we come back and fix it without a paperwork argument.
Homeowners off North Ocean Boulevard and Polo Drive call us because they want a company that treats a 1930s steel casement with the same seriousness as an architect would. Our technicians are background-checked and uniformed. They measure every opening twice, quote manufacturer lines side by side on paper, and they will tell you honestly if a window can be restored rather than replaced. A live person answers the phone 24 hours a day, seven days a week. Not a call center. Not a voicemail tree.
Our Window Replacement Services in Gulf Stream
Historic Window Restoration
Gulf Stream’s housing stock includes some of the finest original steel and wood casement windows in Palm Beach County, and many of them can be restored to meet current HVHZ impact rules without a full tear-out. We rebuild the sash, replace the glass with laminated impact-rated units, and restore the original hardware rather than swapping in a vinyl lookalike. This is the only service category where Gulf Stream’s design code actually works in your favor: restored originals rarely require the same level of architectural review as a full replacement.

Full Frame Replacement
When the original frame is rotted, out of square, or too far gone to hold a new insulated glass unit, a full frame replacement is the honest fix. In Gulf Stream, that means we pull the old frame down to the rough opening, correct any settling or water damage, and set a new frame that carries either a slim-profile or simulated true-divided-light profile depending on what the Town Commission will accept on that facade. Because the town requires both design-review approval and a Palm Beach County building permit, we stage the work so no opening sits unsealed for more than a single day once the approval comes through.

Energy-Efficient Upgrade
A properly specified window on an oceanfront Gulf Stream estate does not work the same way as a window ten miles inland. We specify U-factors and SHGC ratings for a structure that catches salt-laden wind off the Atlantic on one side and reflected heat off the Intracoastal on the other. Low-E coatings, argon fills, and thermally broken frames all matter, but the real energy question in Gulf Stream is whether the window stays sealed against driven rain while hitting the right solar gain number. We quote PGT, CGI, and Simonton lines side by side so you can see the actual performance difference in writing.

Insert Window Replacement
For openings where the original frame is still sound and only the sash and glass have failed, an insert replacement preserves the existing jamb and trim, which Gulf Stream’s design reviewers generally prefer on historic facades. We set a new impact-rated sash inside the existing frame, re-weatherstrip the jamb, and register both warranty layers before we leave. The finished opening keeps its original sightlines, which is exactly what the Gulf Stream Gothic aesthetic demands.
Every one of these services falls under our Window Replacement umbrella, and every job, whether an insert on a 1950s ranch or a full-frame on a 1928 Mediterranean Revival, gets the same Keystone Standard paperwork and the same 90-day promise.

Trusted Brands We Service in Gulf Stream
We install and service more than a dozen manufacturer lines, and for Gulf Stream specifically we lean on the products that routinely survive design review: PGT for custom impact configurations, CGI for large-missile ratings on direct oceanfront exposures, and Simonton for divided-light profiles that read as true muntins rather than snap-in grids. Because Gulf Stream’s review board rejects wide-frame extrusions on historic facades, we keep slim-profile sample kits and Miami-Dade product approval binders ready to go into a submittal packet. If you already have a brand you trust, we’ll work with it. If you need a recommendation for what will actually get approved, we’ll tell you straight.
Common Window Replacement Problems We See in Gulf Stream Homes
- Design-review rejection on standard impact windows. A contractor orders a standard wide-profile impact unit, files the submittal, and the Town Commission rejects it because the sightlines don’t match the original 1920s-1950s proportions. The homeowner now owns glass they can’t legally install. We specify the right profile before any money leaves your pocket.
- Salt-spray corrosion on off-the-shelf aluminum frames. Gulf Stream properties sit between the Atlantic and the Intracoastal, so aluminum frames take salt exposure from two directions. Cheap extrusions and uncoated hardware pinhole and seize within eight to ten years. We specify marine-grade finishes and stainless hardware on every oceanfront job.
- Seal failure from mismeasured rough openings. Original steel casement and double-hung frames from the 1930s and 1940s are rarely square after eighty years of settlement. If the replacement unit is measured to the old frame rather than the rough opening, the insulated glass unit twists under load and the seal fails inside the first year. We measure to the rough opening every time, twice.
- Wrong U-factor for the orientation. A window that performs fine on a north-facing Delray Beach condo will cook a west-facing Gulf Stream bedroom. We look at your specific elevation, overhang, and glass-to-frame ratio before we quote a single product, and we put the numbers on paper for you.

FAQs - Window Replacement in Gulf Stream
Yes. Gulf Stream is one of the only municipalities in Palm Beach County where a window must pass two separate gates: the Florida High-Velocity Hurricane Zone impact mandate and the Town Commission’s architectural review. A window can carry full Miami-Dade large-missile approval and still be rejected for having frame sightlines too wide for the facade. We file both the design-review submittal and the Palm Beach County building permit for you, and we schedule the work so no opening sits half-finished waiting on a committee. Call (813) 320-9346 and we’ll tell you which review path your specific property triggers.
Plan on four to six weeks of added calendar time between the day the submittal is filed and the day a permit is issued, assuming the submittal is complete and correct the first time. A rejected submittal adds another cycle on top of that. That’s why we front-load the design packet with elevations, finish samples, and Miami-Dade product approvals before we order a single unit. The actual installation on a typical Gulf Stream house runs two to five days once approvals clear.
In most cases, the Town Commission will accept simulated true-divided-light bars, provided the muntin profile, spacing, and proportions match the original fenestration closely enough to read as authentic from the street. True divided light is still required on some landmarked facades, but our experience on Polo Drive and North Ocean Boulevard is that a well-detailed SDL unit with a slim frame profile clears review on the first pass. We’ll tell you which route your specific house needs before we spec the windows.
For a direct oceanfront exposure in Gulf Stream, we typically specify a U-factor of 0.40 or lower and a solar heat gain coefficient between 0.25 and 0.30, paired with a thermally broken frame. The salt spray and driven rain make frame material and weatherstripping just as important as the glass package. A window that hits the right numbers on paper but uses a cheap jamb seal will still leak in a nor’easter. We spec the full assembly, not just the glass, and we put the performance numbers in writing.
Yes, in many cases. We rebuild the original steel sash, install laminated impact-rated glass, and restore the original hardware to working condition while meeting current large-missile impact standards. This is often the faster path through Gulf Stream’s architectural review, because restoration preserves the original sightlines without triggering the same level of design scrutiny a full replacement does. On a 1938 Gulf Stream Gothic estate off Polo Drive, our crew replaced twelve original steel casement sashes with custom Marvin impact-rated units using simulated true-divided-light bars and a bronze anodized finish, satisfying the Town Commission and HVHZ code in the same job. Call (813) 320-9346 and we’ll assess whether your originals are candidates for restoration or replacement.
