Window Installation in Miami - Free Measure, Exact Written Quote

Trusted Window Installation for Miami Homeowners

Window installation in Miami isn’t a simple swap. Coastal salt air, hurricane codes, and afternoon sun that can warp a cheap frame in two summers mean the product and the install crew both have to be right. Since 2009, Westlight Windows Miami has installed impact-rated and energy-efficient windows across Dade County, led by Owen Satterfield and backed by a written guarantee on every job. Most installations run $450 – $1,850 per window depending on size, frame material, and whether the opening needs reframing, and we give you that number in writing before any work starts.

Casement Windows

Casement Windows hinge on one side and crank outward, sealing tight against the frame when closed. In Miami, where wind-driven rain finds every gap, that compression seal is the reason so many oceanfront condos in Key Biscayne and Sunny Isles Beach run casements. We install casement units from PGT and CGI with reinforced hinges and multi-point locking hardware. A standard casement installation in Miami runs $550 – $1,200 per window, and heavier coastal-rated units push toward the top of that range. You get the written price before any work begins, and it doesn’t change at the door.

Crank Hardware and Coastal Wear

Salt air is hard on crank mechanisms. We see corroded operator arms and stripped gears most often within a half mile of the water. When we install a casement, we check the crank’s travel and replace worn hardware as part of the job, so the window doesn’t bind the first time you open it after a storm.

Air-Sealing Around the Sash

Casements seal better than sliding windows because the sash presses into the weatherstripping on all four sides. We set reveal gaps evenly and test the lock engagement before caulking the exterior. A casement that closes properly is one of the quietest windows you can put in a Miami bedroom.

Double Hung Windows

Double Hung Windows have two sashes that slide vertically, so you can open the top, the bottom, or both. That’s useful in Miami’s shoulder seasons when you want airflow through the upper sash but don’t want a wide opening at ground level. Westlight Windows Miami installs double hung units from CWS and ECO Window Systems, including versions with tilt-in sashes for cleaning from inside. Expect most double hung installations in Miami to run $400 – $950 per window, depending on glass package and whether the existing frame is sound enough to reuse.

Balance Systems and Smooth Operation

A double hung that slams shut or won’t stay up has a failed balance, usually a worn coil or broken cord. During installation we verify the balance tension matches the sash weight. It’s a small check that prevents a window from dropping on a child’s fingers or refusing to open when you need cross ventilation.

Meeting Rail Alignment

The meeting rail is where the top and bottom sash lock together. If it’s out of alignment, you get air leaks and a weak lock point. We square the frame and shim as needed before securing the window, so the lock engages with a clean click instead of a wiggle.

Vinyl Windows

Vinyl Windows are the most common choice for Miami homes because they don’t rot, don’t corrode, and cost less than aluminum or wood. The frames are extruded PVC, often with insulated chambers that reduce heat transfer. We install vinyl lines from ViewLux and ECO Window Systems, both of which offer Miami-Dade compliant impact options. Vinyl window installation in Miami typically runs $350 – $800 per window. The lower end is a basic single-hung in an existing opening; the higher end is a larger fixed or casement unit with laminated impact glass.

Vinyl Expansion in Direct Sun

Vinyl expands and contracts with temperature, and a dark frame on a west-facing wall in Westchester can move noticeably throughout the day. We leave proper expansion gaps at the perimeter and use flexible sealant instead of rigid caulk in those spots. Skipping that detail is how you get buckled frames two summers in.

Fusion-Welded Corners

Quality vinyl windows have welded corners, not mechanically joined ones. We check that every unit we install is fused at all four corners so water can’t enter the frame channels. It’s the difference between a window that drains properly and one that holds water against your drywall.

Picture Window

A Picture Window is a large, fixed pane that doesn’t open. It’s the window you put where the view matters most: a canal in Aventura, a banyan-lined street in Coral Gables, or a south-facing living room that catches Atlantic light. We install picture windows from PGT and ES Windows, often paired with awning or hopper units or double hungs on either side for ventilation. A large picture window installation in Miami typically runs $700 – $1,850 depending on glass size and whether the opening needs structural reframing. Fixed windows are the least expensive to seal because there’s no moving hardware, but the glass packages for impact zones add cost.

Glass Area and Impact Rating

Once a pane exceeds a certain square footage, Miami-Dade code requires thicker or laminated glass. We’ll tell you before we quote whether your picture window needs impact-rated glass or if standard insulated glass meets code for that wall. We don’t upsell, but we will tell you what’s legally required.

Framing the View

A picture window is only as good as its sightlines. We measure the reveal and set the unit so the glass reads clean from inside and out. On new construction or a resized opening, we frame the rough opening square and level before the window goes in, which keeps the glass from bowing under its own weight.

Bay Window Installation

Bay Window Installation projects a window out from the wall, creating a small ledge or seat inside and adding floor space visually. It’s a three-part assembly: a large center picture window flanked by two angled units, usually casements or double hungs. In Miami, a bay window changes how a living room or kitchen feels, but it also changes the building envelope, so the install has to be done carefully. Bay window installation in Miami runs $1,800 – $5,500 depending on the projection depth, seat and roof construction, and glass package. We give every customer a written price before any work starts, and that price accounts for flashing, structural support, and interior finishing.

Support and Cantilever Engineering

A bay window hangs off the wall, which means it needs support below or cables above, and sometimes both. We assess the wall framing before we quote and tell you if the floor structure can carry the extra load. In older Miami Shores and Brownsville homes, we sometimes add a knee brace or adjust the roof overhang to keep the assembly stable.

Flashing the Seat and Roof

The seat board and mini-roof on a bay window are where leaks start in Miami’s afternoon thunderstorms. We install metal flashing with proper lap order and seal all seams before the finish trim goes on. Water that gets behind the trim rots the framing, and that’s a repair nobody wants to discover two years after install.

Window Contractor

A Window Contractor is the company that installs, replaces, and sometimes supplies the windows themselves, and in Miami the license and insurance matter more than anything. We’re an independently owned and operated Kingswell location, and every job is covered by the Kingswell Guarantee: a written price before work starts, a committed arrival window, a clean job site, and a written guarantee on the completed work. As your window contractor, we handle everything from product selection to final inspection, including pulling Miami-Dade permits when the job requires it. Most window contractors in Miami charge $400 – $1,800 per window installed, and our pricing always lands in that range with the exact number written down before we begin.

What to Check Before You Hire

Ask any contractor whether they’ll give you the price in writing before the crew arrives, and ask who actually shows up on the job. We send background-checked, uniformed technicians on every appointment, and the person who measures the windows is part of the same company that installs them. If a contractor can’t tell you who’s coming to your house, keep looking.

Permits and Miami-Dade Code

Replacing windows in Miami usually requires a permit, and if you’re in a high-velocity wind zone, the windows have to carry a Miami-Dade NOA (Notice of Acceptance). We pull the permits and handle the inspections. A contractor who says you don’t need a permit on a full window replacement in Miami is cutting a corner that can come back on you at resale.

Window Installers

Window Installers are the crew that does the physical work, and in Miami their experience with impact products and coastal weather is what separates a dry wall from a moldy one. Our installers are background-checked and uniformed, so when you open the door in Kendall or North Miami Beach, you know exactly who you’re letting in. Installation labor in Miami typically runs $150 – $450 per window as part of the total price, and our installers handle everything from removing the old unit to hauling away debris. If the work isn’t right within 365 days, we come back and fix it at no charge under the Done Right Promise.

Cutting Old Windows Out Cleanly

Removing an old window in a Miami house built in the 1960s or 1970s often means dealing with stucco, aluminum frames, and occasionally some water damage you didn’t know about. We score the exterior before cutting so the stucco doesn’t crack past the new trim line. It’s slower, but it’s the difference between a clean install and a patched wall.

Setting, Shimming, and Sealing

A window is only as good as the gap around it. We shim the frame so it’s square in the opening, then insulate and seal the perimeter before the interior and exterior trim go back on. Skipping shims causes sashes to bind; skipping insulation is how you get a steady draft through a brand new window.

Brands We Service

We install and stand behind products from eight manufacturer lines, including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That range exists because a 1950s ranch in Brownsville has different needs than a high-rise condo in Sunny Isles Beach, and no single brand is right for every opening.

PGT makes impact windows designed specifically for Florida’s wind codes, and we’ve installed their WinGuard and SpectraGuard lines across Miami-Dade. CGI is the choice for heavy coastal exposure, with strong laminated glass packages and a reputation for standing up to salt spray. CWS and ES Windows give us good mid-range options when a homeowner wants impact protection without the top-tier price, and ECO Window Systems carries energy-efficient packages that help with cooling bills through a Miami August. Whether you have a preference or want us to recommend the right product for your exposure, we’ll match the window to the job, not the other way around. If you want help choosing, our home page has a full overview of how we work.

Signs You Need a Pro Right Now

• You can see daylight around the frame. If light leaks past a closed window, water and wind-driven rain will too. That gap also means the window isn’t providing any meaningful barrier against outdoor air, and in Miami’s humidity, that’s a mold invitation.
• The glass fogs between the panes. Fog between panes means the window’s seal has failed and the insulating gas has leaked out. Once the seal goes, the window’s energy performance drops sharply, and the only real fix is replacing the unit or the glass.
• The window won’t stay open or won’t lock. A broken balance or stripped crank is more than a nuisance; an unsecured window is an entry point. If your window can’t lock, it can’t do the basic job of keeping your house secure.
• You can hear traffic like the window is open when it’s closed. Single-pane or failed windows pass noise straight through. New double-pane units with proper seals cut outside sound noticeably, and that’s a quality-of-life change you’ll feel the first night after install.
• Your cooling bill keeps climbing. Windows are one of the biggest sources of unwanted heat gain in a Miami home. If your AC runs constantly and the windows are original to a house built before the 2000s, they’re likely part of the problem.

Our Process, Step by Step

1. 1
   You call and talk to a real person. Call (850) 753-2730 and a live human answers, any hour, any day. We ask about your home, your windows, the problems you’re seeing, and what you’re hoping to fix. No chatbot, no voicemail queue.
2. 2
   We measure and quote in writing. A background-checked technician comes to your home at the scheduled time, in the window we gave you. We measure every opening, assess the existing frames and stucco, and hand you a written price before any work starts. That price doesn’t change at the door.
3. 3
   We pull permits and order product. If your job requires a Miami-Dade permit, we file it. We order the windows from the manufacturer line we agreed on, sized to the openings we measured. You get a timeline that reflects actual product lead times.
4. 4
   We install, clean, and inspect. Our uniformed installers remove the old windows, set the new ones square and shimmed, seal and flash the perimeter, and haul away all debris. We leave your property cleaner than we found it, then walk you through the finished work before we leave.
5. 5
   We hand you the written guarantee. Every customer gets the Kingswell Guarantee in writing on the day the job is complete. If the work isn’t right within 365 days, we return and correct it at no charge under the Done Right Promise. That’s the whole point of having us do the job.
