Fast, Reliable Custom Windows & Doors Across Sebastian
Custom window and door work in Sebastian runs a wide range, but for a mid-size replacement or custom-shaped unit on a 1980s concrete-block ranch, most homeowners spend between $1,800 and $4,600 per opening installed. Impact-rated glass, oversized panels, and custom geometries push higher, while standard double-hungs on accessible ground-floor openings land lower. If you’re calling from Sebastian, you reach a live person at (772) 279-7983, not a voicemail tree. We dispatch crews who know the lagoon-side salt issue, the post-2004 code requirements, and the particular way 1970s ranchers off Indian River Drive come apart when you start pulling old jalousies.
This page tells you exactly what opening up an older Sebastian home turns up: corroded anchors, hidden rot, and mandatory wind-borne debris upgrades. And it tells you how TruePane prices and handles each surprise before we touch the wall.
Why TruePane Windows & Doors Is Sebastian’s Preferred Custom Windows & Doors Company
We are not the cheapest bid in Sebastian, and we do not try to be. Homeowners here have been through enough contractor roulette to know that cheapest usually means a fogged seal in year four and a door that binds every July. Our Custom Windows & Doors team is led by Dale Kessler, a second-generation glazier who founded TruePane in 2008 on a single rule: if the pane is not true, the job is not done. That rule governs every measurement, every cut, every shim, and every trim nail on every job we run from Roseland down to Fort Pierce.
What you get when you call us in Sebastian is simple. A live person answers, 24 hours a day, seven days a week. The tech who shows up is background-checked, uniformed, and measures every opening twice. You get side-by-side quotes on paper for manufacturer lines from CGI, PGT, and ES Windows, so you see exactly what you are buying and what each option costs. Both warranty layers get registered in writing before the truck leaves your driveway. That is our Keystone Standard. And if something is not done right, we come back and make it right under our Done Right Promise. No paperwork fights, no arguing.
Our Custom Windows & Doors Services in Sebastian
Custom Shape Windows
Sebastian has a lot of homes with arched transoms, radius windows, and half-rounds over entry doors, especially in the ranch and split-level stock built from the 1970s through the 1990s. Big-box stores do not stock these sizes, and a surprising number of contractors try to square off a radius opening with filler. We do not do that. We order the exact curved unit from the manufacturer, double-check the template against the actual opening on site, and set it so the reveal is consistent all the way around. A custom radius window in Sebastian typically runs $2,200 to $5,800 installed, depending on diameter, glass package, and whether it carries an impact rating.

Architectural Grilles & SDLs
Simulated divided lites, or SDLs, are common on homes in Sebastian’s older neighborhoods where homeowners want to keep the traditional look without sacrificing glass performance. We install true SDLs from manufacturers including CGI and ES Windows, with the grille profiles applied permanently to both interior and exterior surfaces so they read as authentic muntins, not snap-in afterthoughts. For a typical 36-by-60-inch double-hung with SDLs and low-E glass, Sebastian customers typically pay $950 to $2,400 per unit, installed.

Oversized Glass Panels
Homes along the Indian River Lagoon side of Sebastian often have picture windows or sliding door walls sized for the view. Replacing an oversized panel means handling glass that can run 60 to 96 inches on a side and weigh hundreds of pounds. It requires a crane or vacuum-lift rig on many lots, and it is not a two-man job. We run these installs with a full crew, proper lift equipment, and safety protocols that keep everyone on the ground in one piece. Oversized impact-rated panels in Sebastian start around $3,500 per opening and can run past $9,000 depending on glass size, structural requirements, and access.

Commercial Storefront Glazing
Sebastian’s commercial buildings along U.S. 1 and the Barber Street corridor include storefronts, medical offices, and small retail in concrete-block structures from the 1980s and 1990s. We replace broken or fogged storefront glass, rebuild aluminum framing, and upgrade to impact-rated storefront systems when required by code. A typical commercial storefront door and sidelite package in Sebastian runs $2,800 to $7,500 installed, depending on frame condition and whether the existing header can carry the new glass weight.

Trusted Brands We Service in Sebastian
We are an authorized installer for more than a dozen manufacturer lines, and on Sebastian jobs we often quote CGI for impact work, ES Windows for high-end custom shapes, and ECO Window Systems for value-driven replacements. Because we order directly from the manufacturers and register both warranty layers on every install, you are never left tracking down a third party if a seal fails or a latch breaks. Parts for common Sebastian applications, including lagoon-side corrosion-resistant hardware, are stocked regionally so we are not waiting on a slow boat for a replacement hinge.
Common Custom Windows & Doors Problems We See in Sebastian Homes
- Corroded aluminum anchors on lagoon-side homes. We have pulled original windows out of 1980s concrete-block ranches off Indian River Drive and found jamb fasteners so rusted from salt aerosol that they sheared during demo. The sash still looked fine from the interior. The frame was barely hanging on.
- Fogged seals on post-2004 hurricane replacements. Hurricanes Frances and Jeanne hit Sebastian within weeks of each other in 2004, and a large cohort of replacement windows went in over the following two years. Many were installed without proper flashing tape. Now those units are hitting 20 years old, and we are seeing widespread seal failure and hidden rot behind the frames.
- Original jalousie and single-pane aluminum in 1970s through 1990s ranchers. These units predate Indian River County’s wind-borne debris requirements and offer almost no resistance to the salt-laden wind that comes off the inlet from both directions. Opening a wall for a remodel triggers a code-mandated upgrade to impact-rated glazing or approved shutters.
- Manufactured-home window sizing off Barber Street and U.S. 1. Manufactured homes use non-standard rough openings that do not match site-built construction. We measure and order custom units sized to the actual opening, which saves you from a contractor who wants to widen the hole or pack the gap with trim.
Pricing for Custom Windows & Doors in Sebastian, FL
Here is what you can expect to pay in Sebastian for the work we do. A standard impact-rated double-hung replacement on a ground-floor concrete-block ranch runs $1,800 to $3,200 per opening. Custom shape windows like radius tops or arches run $2,200 to $5,800. Oversized picture windows and sliding door walls start at $3,500 and go up from there based on glass size and access. Architectural SDL packages add roughly $250 to $700 per unit depending on grille profile and glass package. Manufactured-home units usually land between $900 and $2,200 each because the units are smaller, but every one is ordered to exact size.
What changes the price in Sebastian specifically is the salt-corrosion question. If we open the wall and find rotted framing or sheared anchors, that repair gets priced and approved in writing before we touch another stud. No surprises on the bill, no change orders you never agreed to. Call (772) 279-7983 for a free estimate. We will measure, quote, and walk you through the numbers on paper.

FAQs - Custom Windows & Doors in Sebastian
Sebastian sits directly astride Sebastian Inlet, which means your home gets salt-laden wind from the Indian River Lagoon on one side and near-ocean exposure on the other. That dual-front salt assault corrodes mill-finish aluminum frames and hardware faster than in Vero Beach, which sits slightly inland from the inlet’s direct wind path. We regularly see frames on lagoon-side Sebastian homes with mill finish completely oxidized through within 10 to 15 years, while the same unit 20 miles inland in Fellsmere still looks serviceable. If your frames are pitting or your jamb anchors are rusting, call (772) 279-7983 to schedule a free assessment before the frame fails structurally.
Most often we find rotted wood framing around the rough opening, corroded jamb anchors that shear when the old window comes out, and failed flashing that let water behind the frame for years without anyone noticing. Our crew opened up a 1980s concrete-block ranch off Indian River Drive and found the original aluminum jamb anchors so rusted they sheared during demo, while the single-pane sashes showed pitting and seal failure. We pulled full permits, replaced the rotted framing with pressure-treated stock, flashed the openings with butyl tape, and installed fusion-welded impact-rated vinyl double-hungs with low-E glass and argon fill before the inspector signed off the wind-borne debris compliance. That is the difference between a window replacement and a window job done right.
Yes. Sebastian sits within Florida’s wind-borne debris region under the Florida Building Code, which means any replacement window or door must meet impact-resistance standards or be protected by approved shutters. This applies even when you are replacing one old jalousie with a modern unit. If you are planning a remodel that opens a wall, the inspector will require the entire opening to be brought up to current code. We handle the permitting and the paperwork so the upgrade is priced into the quote before work starts, not sprung on you during inspection.
Fog between panes means the insulated glass unit has lost its seal, and on Sebastian homes we see this frequently on replacements installed in the 2004 to 2006 window. Many of those jobs were rushed after Hurricanes Frances and Jeanne, and a significant share were installed without proper flashing tape, which shortens seal life and invites hidden water damage. If your post-storm windows are fogging, the glass unit needs replacement or the entire sash needs rebuilding. Call (772) 279-7983 and we will tell you which one you are looking at after a free inspection.
Yes. Manufactured homes in Sebastian, including the communities along Barber Street and the U.S. 1 corridor, use rough openings that do not match site-built construction. We measure every opening twice and order custom units to the exact size from manufacturers who cut to our spec. The units are typically smaller, so pricing usually runs $900 to $2,200 per window installed. There is no reason to widen the opening or pack a gap with trim when the correct approach is a properly sized window ordered for the hole you actually have.
For a straight answer on custom windows and doors in Sebastian, call (772) 279-7983. A live person answers, we measure twice, and the quote is written on paper. Estimates are free, and both warranty layers are registered in writing before we leave your driveway.
