AfterWindows & Doors in Westchester, FL
Window and door installation in Westchester typically runs $800-$3,200 per opening depending on framing condition, product tier, and whether the original unit is a pre-Andrew jalousie or single-pane aluminum frame that must be stripped to the masonry. Most Westchester homeowners replace 8-14 openings at once, and our crews complete full-home conversions in 2-4 working days once the NOA-certified order arrives. Call (786) 321-3319 to schedule your measured survey; the written price we leave with you is the price on the final invoice.
We are Sightline Windows & Doors, independently owned and operated under the Haven Standard since 2012. Every one of the 18,000+ openings we have touched began with a measured survey the customer keeps and ended with a documented photo record. In Westchester, that process matters more than in most places, because the housing stock here was built before Miami-Dade’s High-Velocity Hurricane Zone codes existed.
Why Westchester Homes Are Different
Westchester’s dense grid of 1950s-1970s concrete block and stucco homes was built largely before Hurricane Andrew forced Miami-Dade to rewrite its building codes, leaving thousands of units with original jalousie and single-pane aluminum-frame windows that flatly fail the county’s High-Velocity Hurricane Zone standards. Every replacement window or door installed here must carry a Miami-Dade Notice of Acceptance, the strictest product certification in the U.S., and Citizens Insurance and private carriers actively reward full-opening impact protection with meaningful premium reductions, making code-compliant impact-window conversion the dominant engine of this trade in Westchester.
The uniform but aging construction means opening dimensions frequently deviate from modern nominal sizes. In Westchester’s 1950s-60s CBS blocks, window headers were often poured in place with relaxed tolerances, so installers routinely find openings that are out of plumb by half an inch or more. That is enough to bind an impact door or gap an impact window frame against the masonry, voiding both the NOA certification and the homeowner’s insurance discount if not shimmed and sealed to spec on-site. The persistent tropical humidity combined with salt-laden air drifting inland from Biscayne Bay corrodes non-marine-grade aluminum frames, destroys sealants, and rots wood framing far faster than in any city north of the Palm Beaches.
Our Main Westchester Services
Westchester homeowners call us most often for full-window replacement and impact-rated protection. Here is what those jobs involve in this market.
Window Replacement in Westchester
Most Westchester window replacement jobs involve stripping out original jalousie or single-pane aluminum units set into masonry rough openings that require precision anchoring into the block rather than standard wood-stud framing. We measure every opening to the sixteenth, note plumb and square deviation, and order frames that account for the tolerance stack-up common in this era of CBS construction. Window Replacement in Westchester is our most frequent full-home service here.
Impact Windows & Doors in Westchester
Impact-rated conversion in Westchester is not an upgrade; it is a code and insurance requirement for any opening that sees salt air, wind-driven rain, or debris load. We specify PGT and CGI products with current Miami-Dade NOA numbers, pull permits through the county, and pass inspection with the documented photo record included on every job. Impact Windows & Doors in Westchester carries the highest ROI of any replacement category in this ZIP code.
Sliding & Patio Doors in Westchester
Original sliding glass doors in Westchester’s 1960s-70s ranches often sit on corroded aluminum tracks with failed weatherstripping, and the header framing above them was frequently poured with the same relaxed tolerances we see in window openings. We replace with impact-rated multi-panel rollers or lift-and-slide systems, shimmed to plumb and sealed to HVHZ water-infiltration standards. Sliding & Patio Doors in Westchester requires the same measured survey discipline as any fixed window.

AfterWindow Installation in Westchester
Window installation in Westchester means working with 1950s-1970s CBS construction where original jalousie and single-pane aluminum frames are set into masonry rough openings that deviate from modern nominal sizes, and where salt-laden Biscayne Bay air has corroded hardware and degraded seals for decades. Our measured survey captures every deviation; the written quote we produce from that document is the same document that governs the install, with no change orders. Window Installation at Sightline always begins with the survey the customer keeps.
Single & Double Hung Windows
Signs you need it
Your original aluminum single hungs rattle in the frame, the balances no longer hold the sash open, or you can feel air movement around the meeting rail during a northeast blow.
What it costs in Westchester
Single and double hung window installation in Westchester typically ranges from $850 to $1,650 per opening for vinyl or aluminum impact-rated units, with wood-clad and high-performance glazing options at the upper end.
How we do it
We remove the existing frame to the masonry, anchor the new impact-rated unit with Tapcon or expansion fasteners into the block, shim to plumb against the out-of-tolerance headers common here, and seal with backer rod and silicone to HVHZ water-infiltration standards.
Horizontal Roller Windows
Signs you need it
The rollers grind, the sash jumps the track, or the locking mechanism has corroded to the point that the window cannot be secured.
What it costs in Westchester
Horizontal roller window installation in Westchester typically ranges from $900 to $1,750 per opening, with multi-point locking and laminated glass upgrades pushing toward the higher figure.
How we do it
We measure the rough opening for square after stripping the old unit, set the impact-rated frame on a bed of sealant, fasten through the jambs into the CBS block, adjust the roller carriage for smooth travel, and document the sealant bead and fastener pattern with photos.
What Window Installation Costs in Westchester
| Item | Typical range in Westchester |
|---|---|
| Single or double hung window, vinyl impact-rated | $850 - $1,650 |
| Horizontal roller window, aluminum impact-rated | $900 - $1,750 |
| Full-home replacement (10-14 openings, mixed types) | $11,000 - $22,000 |
Do you pull permits for window installation in Westchester?
Yes. Miami-Dade County requires a building permit for any window replacement that changes the frame or glazing type, and we pull that permit as part of our scope. The inspection pass is documented in your photo record, and the NOA paperwork travels with the job file. Call (786) 321-3319 to schedule your measured survey; estimates are free.
Will the price change once work starts?
No. Haven Clause 1 means the written price from our measured survey is the final price. We have completed 18,000+ openings under that rule since 2012, and Westchester jobs are no exception. The only variable is concealed structural damage we could not have detected, which we document and discuss before proceeding. Call (786) 321-3319 for your written quote.
Door Installation in Westchester
Door installation in Westchester confronts the same pre-Andrew CBS construction as window work, with the added complexity of operable hardware, threshold drainage, and the higher wind-load concentration at entry points. Original wood-frame entry doors in this neighborhood have often rotted at the sill from decades of salt-air exposure, while unprotected aluminum frames have corroded to the point that the deadbolt no longer seats. Our measured survey captures jamb plumb, threshold level, and header load path before we quote.
Hurricane-Proof Front & Entry Doors
Signs you need it
Your front door leaks water at the sill during summer storms, the frame has separated from the block, or your insurance carrier has flagged non-impact entry protection for premium adjustment.
What it costs in Westchester
Hurricane-proof front and entry door installation in Westchester typically ranges from $1,800 to $3,500, with fiberglass impact-rated slabs and multi-point hardware at the upper end and steel-laminate options in the middle.
How we do it
We strip to the masonry rough opening, install a composite or aluminum impact-rated frame with positive drainage at the sill, hang the slab with adjustable hinges, engage the multi-point lock system, and seal with backer rod and HVHZ-grade sealant before inspection.
French & Double Doors
Signs you need it
The inactive leaf no longer seals against the astragal, you see daylight between the doors when closed, or the original unit is a non-impact pair that violates current HVHZ standards.
What it costs in Westchester
French and double door installation in Westchester typically ranges from $2,400 to $4,200 for impact-rated pairs, with retractable screen and high-performance glazing upgrades available.
How we do it
We set the impact-rated frame plumb against the CBS block, install the active and inactive leaves with adjustable hinges and a flush bolt or multi-point astragal, verify the meeting stile gap with feeler gauges, and document the lock engagement and sealant pattern.
What Door Installation Costs in Westchester
| Item | Typical range in Westchester |
|---|---|
| Hurricane-proof front & entry door, impact-rated | $1,800 - $3,500 |
| French & double doors, impact-rated pair | $2,400 - $4,200 |
| Standard replacement door, non-impact (interior or protected entry) | $1,200 - $2,200 |
Do you pull permits for door installation in Westchester?
Yes. Any exterior door replacement in Miami-Dade requires a permit, and impact-rated units must match the NOA on file with the county. We handle the application, schedule the inspection, and document the pass in your photo record. Call (786) 321-3319 to schedule your measured survey; estimates are free.
How long does a typical door installation take?
A single entry door replacement takes one working day once materials arrive; French or double door pairs with sidelights may take two. Lead time for NOA-certified impact doors is currently 4-6 weeks from order. We do not start until the written price is agreed and the permit is approved. Call (786) 321-3319 to check current lead times.
Energy-Efficient Windows in Westchester
Energy-efficient window installation in Westchester addresses a specific failure mode of the neighborhood’s original single-pane aluminum units: solar heat gain that forces air conditioning systems to cycle continuously, and conductive loss that makes south- and west-facing rooms uninhabitable in August. The same salt-air corrosion that destroys hardware also degrades thermal breaks in older aluminum frames, so efficiency gains here require full-frame replacement with modern glazing packages, not insert windows. Energy-Efficient Windows from Sightline are specified by U-factor and SHGC, not by brand margin.
Low-E & Argon Gas Glass
Signs you need it
Your electricity bill spikes June through September, furniture and flooring near south-facing windows show fading, or the glass itself radiates heat you can feel from three feet away.
What it costs in Westchester
Low-E and argon gas glass packages in Westchester typically add $120 to $280 per opening above base impact-rated glazing, with soft-coat Low-E and triple-silver coatings at the higher end.
How we do it
We specify the coating stack and gas fill based on orientation and shading, order from our CWS or ECO Window Systems lines with documented U-factor and SHGC ratings, and verify the label matches the order at delivery before install.
ENERGY STAR Replacement Windows
Signs you need it
You are replacing windows anyway and want the documented efficiency performance that qualifies for utility rebates and resale disclosure.
What it costs in Westchester
ENERGY STAR replacement windows in Westchester typically range from $950 to $1,850 per opening installed, with the certification included in the product label and our quote.
How we do it
We match the NFRC label data to your home’s orientation and cooling load, specify from our ViewLux or PGT lines with current ENERGY STAR qualification, and include the label documentation in your job file for rebate submission.
What Energy-Efficient Windows Costs in Westchester
| Item | Typical range in Westchester |
|---|---|
| Low-E & argon upgrade, per opening | $120 - $280 add-on |
| ENERGY STAR replacement window, installed | $950 - $1,850 |
| Full-home efficiency package (10-14 openings, Low-E/argon) | $12,500 - $24,000 |
Will energy-efficient windows lower my electric bill in Westchester?
Yes, measurably. We have measured frame surface temperatures drop 15-25 degrees after Low-E/argon conversion on west-facing CBS walls in Westchester, and the reduced cooling load typically shows on the FPL bill within two billing cycles. The exact savings depend on shading, orientation, and your AC system’s condition. Call (786) 321-3319 for a load-oriented survey.
Do energy-efficient windows still meet HVHZ impact requirements?
Yes. Every energy-efficient window we install in Westchester carries both the Miami-Dade NOA and the NFRC performance label; the coatings and gas fill are inside the laminated or insulated glass unit, not a substitute for impact resistance. We do not sell efficiency at the expense of code compliance. Call (786) 321-3319 to review the dual-certification documentation.
Impact Garage Doors in Westchester
Impact garage door installation in Westchester is one of the most consequential upgrades a pre-Andrew CBS homeowner can make, because the garage door is typically the largest unprotected opening on the structure and the most frequent point of failure in a wind-load event. Original flat-panel or thin-gauge raised-panel doors in this neighborhood offer no resistance to debris impact and minimal wind-load capacity, and their failure pressurizes the attic space, compromising the roof assembly. Impact Garage Doors from Sightline are specified by design pressure rating and cycle life, not by panel style alone.
Hurricane-Rated Garage Doors
Signs you need it
Your garage door flexes visibly in a thunderstorm gust, the track is unreinforced 2-inch strut, or your insurance inspection noted non-impact garage protection.
What it costs in Westchester
Hurricane-rated garage door installation in Westchester typically ranges from $2,200 to $4,800 for a single-car opening and $3,400 to $6,200 for double-car, with wind-load rating and insulation level as the primary price drivers.
How we do it
We measure the opening for square and header capacity, specify a door and track assembly with the Miami-Dade NOA and design pressure rating for your exposure category, install with heavy-gauge vertical struts and reinforced brackets, and connect to your opener with a documented force-setting check.
Wind-Load Code Compliance
Signs you need it
You are selling or refinancing and the inspection flagged the garage door for non-compliance with current HVHZ standards, or you are replacing the door after a storm-damage claim.
What it costs in Westchester
Wind-load code compliance conversion in Westchester typically ranges from $2,800 to $5,400 including the door, track, hardware, and permit, with engineering letter and inspection documentation included.
How we do it
We verify the exposure category and wind speed requirement for your Westchester address, specify the appropriate design pressure from our Mr-Glass or Therma-Tru lines, pull the permit, install to the NOA details, and pass inspection with the photo record in your file.
What Impact Garage Doors Costs in Westchester
| Item | Typical range in Westchester |
|---|---|
| Hurricane-rated garage door, single-car | $2,200 - $4,800 |
| Hurricane-rated garage door, double-car | $3,400 - $6,200 |
| Wind-load code compliance conversion (door, track, permit) | $2,800 - $5,400 |
Do I need a permit to replace my garage door in Westchester?
Yes. Miami-Dade requires a permit for any garage door replacement that changes the wind-load rating or track hardware, and impact-rated units must be installed to the exact NOA details. We pull the permit, schedule inspection, and document the pass. Call (786) 321-3319 to schedule your measured survey; estimates are free.
Will an impact garage door work with my existing opener?
Usually, but the force and travel limits must be recalibrated for the heavier door assembly, and older openers may lack the torque or safety sensor configuration for current code. We test and document the opener function as part of every install, and we flag replacement needs before we quote, not after we start. Call (786) 321-3319 to review your opener model.
Custom & Geometric Windows in Westchester
Custom and geometric window installation in Westchester solves a problem specific to this neighborhood’s 1950s-70s CBS construction: the original builder-grade windows were often installed as stock rectangles even where an arched header or angled gable called for a shaped unit, leaving homeowners with flat-topped replacements that fight the architecture. We also see oversized openings in ranch-style living rooms where a single picture window was meant to frame the backyard, but the original unit has fogged, leaked, or failed structurally. Custom & Geometric Windows from Sightline are measured to the finished opening, not to a catalog grid.
Geometric & Shaped Windows
Signs you need it
Your arched or trapezoid opening currently holds a flat-topped replacement that was caulked into place, or you are renovating to restore the original architectural intent of a 1960s ranch.
What it costs in Westchester
Geometric and shaped window installation in Westchester typically ranges from $1,400 to $3,200 per opening, with radius tops, trapezoids, and compound shapes at the higher end due to templating and lamination complexity.
How we do it
We build a full-scale template on-site from the existing opening or the architect’s drawing, transmit the radius and angle measurements to our CGI or PGT custom lines, verify the NOA covers the specific geometry, and install with the same masonry anchoring and HVHZ sealing as any standard unit.
Oversized Openings
Signs you need it
Your living room picture window has failed seals between the glass lites, the frame has sagged under its own weight, or you want to combine multiple small openings into one larger impact-rated unit.
What it costs in Westchester
Oversized opening window installation in Westchester typically ranges from $2,800 to $5,500 per unit, with the price driven by glass thickness, reinforcement requirements, and the crane or specialty handling needed for units over 120 pounds.
How we do it
We engineer the header reinforcement if the opening is being widened, specify laminated glass thickness and frame depth for the span from our ES Windows or ViewLux lines, coordinate delivery with appropriate handling, and install with a crew sized to the unit weight and site access.
What Custom & Geometric Windows Costs in Westchester
| Item | Typical range in Westchester |
|---|---|
| Geometric & shaped window (radius, trapezoid, compound) | $1,400 - $3,200 |
| Oversized opening window | $2,800 - $5,500 |
| Custom impact window, full-home package (4-6 special shapes) | $8,500 - $16,000 |
How long does a custom window order take in Westchester?
Custom and geometric windows typically ship 6-10 weeks from template approval, with oversized units at the longer end due to glass lamination scheduling. We do not template until the measured survey is complete and the written price is accepted, so the production clock starts clean. Call (786) 321-3319 to schedule your survey and review current lead times.
Can you match a custom shape to my original 1960s window?
Yes. We have templated and replaced radius-top, hexagonal, and gable-end units in Westchester’s 1950s-70s ranches, matching the sightline and muntin pattern from photos or remaining originals. The new unit will carry current NOA certification and laminated impact glazing; the shape is limited only by the structural opening and the manufacturer’s forming capability. Call (786) 321-3319 to review your specific geometry.

FAQs About Windows & Doors in Westchester
Some Westchester subdivisions, particularly the 1960s-70s planned units, maintain architectural review committees that require product samples and color matching before exterior modification. We provide the manufacturer data sheets, NOA documentation, and finish samples for your submittal, but we do not interface directly with your HOA; that remains your responsibility as the homeowner.
Clear access to each opening, including furniture moved three feet back, and have your current insurance declaration page if you are seeking impact-rated premium reduction documentation. The survey itself takes 45-90 minutes for a typical Westchester home, and you keep the written measurement document whether or not you proceed.
Jalousie windows are common in Westchester’s 1950s-60s stock and flatly fail current HVHZ standards; every one we have encountered requires full-frame replacement with a fixed or operable impact-rated unit. We measure the masonry rough opening, account for the blade removal and sill modification, and specify a replacement that restores the ventilation function with code-compliant protection.
Call (786) 321-3319 to schedule your free measured survey. The written price we leave with you is the price on the final invoice, and every job is covered by our 365-Day Done Right Promise under the Haven Standard.
