Get your free estimateFast, Reliable Window Replacement Across St. Augustine
Window replacement in St. Augustine usually means one of two jobs: swapping rotted wood sashes or failed single-pane glass for modern, code-rated units, or matching the architectural profile HARB expects in a 1900s coquina or wood-frame home. Most St. Augustine projects run between $700 and $2,400 per opening, depending on whether the install calls for standard vinyl, impact-rated glazing, or a custom wood replica. Our Window Replacement crew lives with the city’s two overlapping rulebooks every week: St. Augustine‘s historic preservation standards near the Plaza and the Florida Building Code’s wind-borne debris rules everywhere else. Keith Yamada leads the team you’ll actually see at your door, and the phone number for a free written estimate is (904) 914-3691.
Why Lightwell Windows Jacksonville Is St. Augustine’s Preferred Window Replacement Company
We’re not the company that mismeasures a jib window on a 1920s San Marco Avenue bungalow and shrugs. Keith Yamada runs every St. Augustine job personally, and the crews he sends are background-checked, uniformed, and trained on the specific failure patterns of coastal Florida construction. When a Davis Shores homeowner calls about fogged glass or a jalousie that won’t close, we know the home was probably built on a concrete slab in the 1950s, that the original window openings are non-standard, and that the east-facing wall takes direct salt spray off Salt Run. That’s not trivia. It changes which frame material, which sealant, and which anchoring schedule we specify.
St. Augustine customers regularly tell us the same three things: the price on the written estimate matched the final invoice, the crew laid drop cloths before touching a single window, and someone answered the phone when they called with a question at 7 p.m. We run every job through the Cedarwell Care Promise, which has been our operating rule since 2010: shoe covers, a photo of the clean-up before we leave, pet-safe caulks and sealants wherever there’s an alternative, and quiet tools during nap time if that’s what the family’s day requires. If a finished window is not right, the 365-Day Done Right Promise means we return and make it right, no debate and no countdown.

Window Repair in St. Augustine
Window Repair in St. Augustine frequently means addressing what the salt air, humidity, and eighty-year-old framing have done to an otherwise sound opening. Jacksonville Beach and Palatka homeowners can sometimes defer a failing sash for a season; on a marsh-front lot off Mizell Road or a raised Victorian near the bayfront, deferred repair turns into a rot pocket and a water stain on the interior plaster within eighteen months. We see it constantly: a homeowner notices the lower sash is stuck about a quarter-inch from the sill, and by the time we pull the unit, the framing behind the stucco needs a partial sill replacement too. A straightforward window repair in St. Augustine, depending on the extent of frame rot and hardware failure, typically runs $300 to $900 per window, with the most common repairs falling between $450 and $650 when no sill or rough-opening work is required.
When a St. Augustine Homeowner Needs Window Repair
Fog between the panes means the insulated glazing unit has lost its seal, and it’s not a cosmetic issue: the gas fill is gone, the glass is no longer doing its thermal job, and on an impact-rated window the seal failure can compromise the unit’s rated performance. We replace failed IGUs on PGT, CGI, and CWS units regularly without replacing the surrounding frame. Sashes that seize shut from salt corrosion are another everyday call, particularly on canal-front streets in Lighthouse Park where the aluminum hardware has spent decades in airborne moisture. We replace the balances, the pivot pins, or the full sash track, and we test the operating force so the window actually opens when a kid’s bedroom needs air at night.
Repair Precedes Replacement Only When the Number Makes Sense
If a jalousie window in a Davis Shores rancher has multiple cracked louvers, a bent operator crank, and a missing frame clip, we will tell you. The repair is real and we do it, but a jalousie is an inherently leaky design from the 1950s, and putting several hundred dollars into one when you plan to live in the home another decade may be the wrong math. We write both options on the estimate: repair cost, replacement cost, and the energy difference between the two. You decide with numbers in front of you, not after a sales presentation.
Window Replacement Company in St. Augustine
A Window Replacement Company in St. Augustine has to be fluent in two code regimes that no neighboring city has to reconcile. Inside Historic Districts 1 and 2, the Historic Architectural Review Board reviews window work against guidelines that specify original materials, muntin profiles, and reveal depth; a homeowner who buys off-the-shelf vinyl replacements before checking district boundaries can end up with windows they cannot legally install. Outside the HARB districts, the Florida Building Code’s HVHZ wind-borne debris provisions govern the entire city, driven by the hurricane wind maps that shift block by block near the Matanzas River and the Atlantic coast. Full replacement projects in St. Augustine generally run from $850 to $2,400 per opening, with insert replacements between $600 and $1,600, and custom historic wood replicas at the upper end and beyond when true divided lites and custom glass are required.
Full Frame and Insert Replacement Differences in an Old City
Full frame replacement pulls the entire old window down to the rough opening, which is what a 1920s wood-framed house near the Lincolnville Historic District usually needs because the original weights, cords, and pulley pockets are gone or rotted. We re-flash the opening, install new interior and exterior casing, and match the sill nosing profile to the original so the HARB reviewer sees what the house always had. Insert replacement leaves the existing frame in place and fits a new unit inside it, which works well in mid-century concrete block and modern coastal construction where the opening is square and the surrounding frame is sound. On a 1980s stucco home off Lewis Speedway, insert units are frequently the cleanest, least disruptive path, and the job can finish in a day or two with the family still in the house.
When a Homeowner Feels the Decision Press
You’ll know you need replacement, not repair, when the windows are original to a pre-1980 build, the glass is single pane, and the frames are the wood or aluminum the house came with. Single-pane, single-glazed windows in St. Augustine’s humid, salt-leached climate lose the fight against condensation, mold on the interior sill, and heat gain that pushes the AC to run all afternoon just to hold 78 degrees. If you’re running your hand along the lower sash and feeling a draft, or you’ve seen water pooling on the interior sill after a hard summer storm, the opening is telling you it’s time. The replacement conversation we have most often in St. Augustine is the one that starts with “I just want my energy bill to stop punishing me every August,” and ends with a written price and a two-day install plan.
Trusted Brands We Service in St. Augustine
We service and install units from the brands that actually hold up in this city’s climate: PGT for impact-rated aluminum and vinyl, CGI for high-design-pressure laminated products in exposed coastal locations, CWS for architectural aluminum in condominium and townhome applications, and ViewLux for fiberglass lines that resist salt corrosion. Having those lines on hand means we’re not pushing a single vendor’s catalog onto a house that needs something else; a 1905 Aviles Street wood-frame home gets a different recommendation than a 2004 Avila Circle stucco home, and both get a written price before anything is ordered. We stock common PGT and CWS hardware, sash balances, and replacement glass locally for St. Augustine customers, so a warranty hardware failure doesn’t mean a three-week wait while parts cross state lines.
Common Window Replacement Problems We See in St. Augustine Homes
- Design pressure mismatches near the water. St. Augustine has HVHZ wind maps that vary block by block. A louvered porch or a second-story overhang near the Matanzas River pushes the window into a higher DP rating than the deep-inland quote a contractor gave three weeks earlier. We check the address against the exposure category before we ever order glass, because an under-specified unit is a structural risk in a named storm.
- Vinyl frames purchased before the HARB question was asked. Homeowners in Historic Districts 1 and 2 sometimes buy vinyl replacements on sale, then learn HARB won’t approve anything that alters the original sash profile or jamb depth. Those windows sit in a garage while the owner starts over with wood replicas and true divided lites. We always check the district map on the first phone call, before any product recommendation.
- Salt-air corrosion on aluminum within a half-mile of Salt Run or the Intracoastal. Non-marine-grade hardware seizes within two years, and the weep holes clog with salt scale. By the time the failing unit is pulled, the real damage has been happening behind the stucco: a rotten sill that needs replacement before the new window can go in.
- Jalousie leakage in Davis Shores and Lighthouse Park. The original 1950s jalousie windows on those streets were never designed to seal against Florida humidity or driving rain. Every louver is a leak path, the operator cranks bind, and the frame clips rot. Most homeowners replace them all at once with Miami-Dade NOA-approved casement or horizontal roller units, and the afternoon AC chase finally ends.

AfterPricing for Window Replacement in St. Augustine, FL

FAQs About Window Replacement in St. Augustine
Yes, HARB does allow impact-resistant windows in historic homes, but only when they replicate the original material, muntin profile, and reveal depth; a 1905 wood-frame house on Aviles Street will almost always need a wood replica with true divided lites and laminated impact glass, and HARB’s guidelines historically push toward aluminum-clad wood or solid wood units rather than vinyl. The board’s job is to preserve the street-facing appearance that makes St. Augustine what it is, and modern manufacturers like PGT and CGI build wood-core impact units that meet both the look and the large-missile wind code. We file the HARB submittal packet for you, including window elevations, product cut sheets, and the Florida Product Approval documentation, and we schedule the install after the approval is in hand. For a specific answer on your block, call (904) 914-3691 and we’ll check the district map while you’re on the phone.
Budget six to nine weeks for HARB review on a full window replacement in the Lincolnville Historic District, and sometimes more if the board’s calendar backs up during a holiday season. The submittal goes in on the board’s posted deadline, the staff reviews it for completeness within two weeks, and then it lands on a public meeting agenda for the appointed board to consider. We prepare the packet so it clears staff review on the first pass, we attend the meeting if the homeowner wants us there, and we do not order any windows until the approval is in writing because a rejected submittal costs you re-review, not just delay. During the waiting period we handle the other pieces: site measurements, rough opening inspection, and the Florida Product Approval paperwork for St. Johns County. The work itself typically takes one to three days per opening once we start.
Yes, a 1920s Spanish Revival home near the St. Augustine bayfront sits squarely in the HVHZ wind-borne debris region, and second-story windows at that elevation and exposure get a higher design pressure requirement than a single-story interior block home. The window has to carry a Miami-Dade or Florida Product Approval that matches the specific wind zone from the building’s address, and a louvered balcony or an overhang can push the rating up further. We pull the address’s wind map before quoting, specify a unit from PGT, CGI, or CWS with the matching DP rating, and file the product approval paperwork with the St. Johns County Building Department so your wind mitigation inspection has what it needs on the first pass. Most bayfront homes in that build vintage also need the original steel or wood casement hardware matched or replaced, and we schedule that work into the same opening so you’re not paying for scaffold time twice.
Yes, in most Davis Shores homes the original jalousie opening can accept a modern replacement unit without reframing, because the rough opening behind a 1950s jalousie is typically a clean rectangle in a concrete block wall. We pull the jalousie and its frame, prepare the opening, and set a PGT WinGuard casement or horizontal roller unit sized to the block opening. On a 1956 concrete-block home in Davis Shores, our crew replaced a wall of leaking jalousies with Miami-Dade NOA-approved PGT WinGuard casements using laminated glass interlayers to meet the home’s large-missile rating. We filed the Florida Product Approval paperwork with St. Johns County, the wind mitigation inspection cleared on the first pass, and the homeowner finally stopped chasing the AC thermostat every afternoon. Your specific opening gets measured before anything is ordered, and if the framing is compromised we show you photos before we touch anything.
You need the Florida Product Approval number for each installed window, a completed Uniform Mitigation Verification Inspection Form signed by a licensed inspector, and documentation that the units meet the design pressure rating for your home’s wind zone. We keep those product approval numbers on file for every PGT, CGI, CWS, and ViewLux unit we install in St. Augustine, and we hand you a packet at the end of the job with the approvals, the permit closure details, and the inspection notes the inspector will reference. In many cases the install itself clears the wind mitigation question, particularly in Davis Shores and Lighthouse Park where the original single-pane jalousies were providing zero credit. Call (904) 914-3691 and we’ll walk you through the paperwork checklist for your specific home.
