Fast, Reliable Window Replacement Across Gulf Stream
Window replacement in Gulf Stream costs between $1,800 and $4,200 per opening for impact-rated units in 2026, with full-frame work on older Bermuda Colonials typically running $2,800 to $5,600 when structural repairs and Architectural Review compliance are factored in. Gulf Stream sits on the barrier strip along A1A, and the salt air off the Atlantic punishes window hardware faster than almost anywhere else in Palm Beach County. If you live in Gulf Stream and your original jalousie or single-pane casement windows are binding, leaking, or failing to close square, call us at (954) 280-4413. We know exactly what the Town Architectural Review Board will require before the first permit is pulled.
You are not shopping for the cheapest bid. You are looking for the company that will still answer the phone in ten years when the warranty question comes up. That is the work we do, and Gulf Stream is one of the towns we know best.
Why TruePane Windows & Doors Is Gulf Stream’s Preferred Window Replacement Company
We have replaced windows in Gulf Stream for long enough to know that every street here has its own relationship with the ocean. A home on Polo Drive faces different wind exposure than one tucked off Harbour Drive, and the Architectural Review Board looks at both with the same strict eye. Our Window Replacement crews understand that a white frame is not a suggestion in this town. It is a condition of approval.
Dale Kessler founded TruePane in 2008 on a rule that still hangs on the whiteboard: if the pane is not true, the job is not done. We carry that into every Gulf Stream home we open. Our technicians are background-checked and uniformed. They measure every opening twice. They register both manufacturer warranty layers in writing before the truck leaves your driveway. That is The Keystone Standard, and it applies to a $1,800 insert just as much as a $40,000 whole-house replacement.
When you call us about window replacement in Gulf Stream, a live person answers. Not a voicemail tree. A person who can schedule your estimate and tell you how long the Architectural Review process typically takes right now. That matters when a permit delay changes your timeline.
Our Window Replacement Services in Gulf Stream
Full Frame Replacement
Full frame replacement means we remove the entire existing window down to the rough opening, inspect the framing, repair or replace rotted wood or corroded steel, and set a new impact-rated unit with new flashing. In Gulf Stream, this is the most common job we do, because the original windows in 1950s and 1960s Bermuda Colonials were never designed for today’s wind loads. A typical full frame replacement in Gulf Stream runs $2,800 to $5,600 per opening, with the spread driven by what we find once the stucco comes off.

Insert Window Replacement
An insert fits a new window inside the existing frame, preserving the exterior trim and stucco. It is a cleaner, faster job when the original frame is still sound and square. In Gulf Stream, salt-air corrosion frequently means the frame is not sound. We probe the jambs before we quote an insert, because installing over hidden rot creates the very callbacks our Done Right Promise exists to prevent. Inserts in Gulf Stream typically run $1,800 to $3,200 per opening for impact glazing.

Storm Window Replacement
For some mid-century Gulf Stream homes, the right solution is a storm-rated secondary glazing system layered over existing windows. It buys energy savings and wind protection without triggering full Architectural Review in every case. But be careful: the Town’s review requirements can still apply depending on mullion profile and frame color. We will tell you up front, in writing, whether your storm window plan needs town review. Typical storm window packages run $900 to $1,800 per opening.

Energy-Efficient Upgrade
Replacing single-pane jalousies with modern insulated glass changes the way a Gulf Stream home holds temperature. The coastal sun here is unrelenting, and rooms facing the Intracoastal can cook by noon. We carry ENERGY STAR impact-rated lines including Andersen and PGT with low-E coatings tuned for south Florida exposure. An energy retrofit package in Gulf Stream runs $2,200 to $4,800 per opening depending on glass package and frame material. Gulf Stream homeowners who upgrade typically see a real difference in the first full summer.

Trusted Brands We Service in Gulf Stream
We are an authorized installer for more than a dozen manufacturer lines, but for Gulf Stream we most often quote Andersen service in Gulf Stream, PGT, and ES Windows side by side on paper so you can compare frame profiles, glass packages, and warranty terms without guesswork. The Architectural Review Board’s white-frame, traditional-mullion requirement narrows the field considerably, and these three lines offer impact-rated products that meet the town’s aesthetic standard. We keep relationships with local suppliers tight so replacement hardware and warranty parts for Gulf Stream customers do not sit in a warehouse queue.
Common Window Replacement Problems We See in Gulf Stream Homes
- Original jalousie and single-pane casement windows failing wind code. These were installed when Gulf Stream was first developed in the 1950s and 1960s. They are neither impact-rated nor compliant with current Palm Beach County wind-speed design requirements, which exceed 150 mph for oceanfront exposure.
- Salt-air corrosion of hidden jamb fasteners. The barrier strip location means constant airborne salt. Fasteners, hinge hardware, and even frame corners corrode at rates homeowners living three miles west on Federal Highway never experience. We regularly open Gulf Stream walls to find sill screws reduced to orange dust.
- Architectural Review rejections on non-conforming replacement windows. A homeowner installs a non-impact or even impact-tested window without pre-approval, only to find the frame color or mullion width falls outside the Bermuda Colonial profile standard. Tear-out and re-permitting follows, and the project cost doubles.
- Improper flashing over old wood bucks letting salt spray wick into the rough opening. Flashing tape from the original build dries out, cracks, and separates. Salt moisture gets behind the stucco, rots the sill, and triggers a code-mandated structural repair before a new window can be set. This is not a $400 patch job once it is open.

FAQs - Window Replacement in Gulf Stream
Yes, in practice, you should schedule one. Gulf Stream’s Architectural Review process can reject an impact window that passes every Florida Building Code test if the exterior frame width, color, or mullion pattern deviates from the Bermuda Colonial standard. We recommend a pre-application meeting before any contract is signed so product selection happens once, not twice. Call (954) 280-4413 and we will walk you through the current review timeline.
Yes. The jalousie windows come out, and impact-rated casement or fixed units go in, provided the replacement carries the approved white frame and traditional mullion proportions the town requires. Andersen impact-rated casements with white fusion-welded frames and matching mullion patterns are a common approved choice for Energy-Efficient Windows - Gulf Stream projects. We handle the permit, the review process, and the install under one contract.
Opening the walls on a 1950s or 1960s Gulf Stream home frequently reveals corroded steel lintels, failed flashing tape, rotted sills at the wood buck, and framing that was undersized even when it was new. Under current code, those conditions must be repaired before the new window is set. We write structural repair allowances into every full-frame quote so you see the possible cost before the first screw comes out.
Gulf Stream sits on the barrier strip along A1A with the Atlantic on one side and the Intracoastal Waterway on the other. Constant airborne salt deposits onto frame corners, hinge pins, and fasteners, accelerating corrosion far beyond what inland Palm Beach County homes experience, which is why we also recommend Glass Railing Systems in Gulf Stream for coastal exposure. We use marine-grade fasteners and stainless hardware on every Gulf Stream install.
Yes. Several ENERGY STAR impact-rated lines, including Andersen and PGT, offer white fusion-welded frame profiles and traditional mullion configurations that meet the town’s Bermuda Colonial standard. We quote manufacturer lines side by side on paper so you can see the approved products and the warranty terms in writing before you choose. Call (954) 280-4413 for a free estimate in Gulf Stream.
What We Do When the Walls Come Open in Gulf Stream
Here is the part no one tells you about window replacement in Gulf Stream. You sign a contract for four windows. The crew opens the first wall. What they find behind the stucco determines whether this is a two-day job or a two-week job.
On a 1960s Bermuda Colonial off Polo Drive, our crew pulled original jalousie windows to find corroded steel lintels and dried-out flashing tape behind the stucco. The fasteners in the jambs had turned to rust. We opened the walls under permit, replaced the undersized framing, and installed Andersen impact-rated casements with white fusion-welded frames and mullion patterns that matched the Architectural Review Board’s approved profile. Then we rebuilt the flashing with modern tape before re-cladding. That is the difference between a crew that knows Gulf Stream and one that has never worked a barrier-strip home.
We inspect first. We write structural allowances into the contract. Any surprise gets a written price and your approval before we touch it. No line items appear on the final bill that you did not sign off on. That is a square deal, and it is the only way we work in this town.
