Trusted Impact Windows & Doors for Kendall Homeowners
Impact windows and doors in Kendall typically run $890-$2,400 per opening depending on size, glazing spec, and whether the installation requires HVHZ-rated hardware. Most full-home retrofits in the area are scoped and priced within a single measured survey visit, with installations scheduled once permits are cleared through Miami-Dade County. Call (786) 321-3319 to book a measured survey; the written quote you receive is the same document our crew works from.
Since 2012, Sightline Windows & Doors has installed more than 18,000 openings across South Florida, including Coral Gables Impact Windows & Doors projects, under the Haven Standard. Every job begins with a measured survey the customer keeps, and every job ends with a documented photo record. In Kendall, we regularly work in neighborhoods where the original 1980s and 1990s window stock still carries pre-Andrew ratings, or where newer construction needs HVHZ compliance documentation for wind mitigation inspections. The soil in western Kendall, particularly around the Snapper Creek basin, shifts seasonally; we’ve documented frame racking in openings that passed visual inspection but failed plumb-by-sightline measurement. Our crews are background-checked, uniformed, and identified by license number before arrival, per Haven Clause 3.
What Our Impact Windows & Doors Service Includes
Impact-Resistant Windows
Impact-resistant windows are laminated glass units tested to withstand missile impact and cyclic pressure loads per Miami-Dade County protocol PA 201, 202, and 203. In Kendall, these are required for any new construction or replacement within the High-Velocity Hurricane Zone and are the standard upgrade for homeowners seeking wind mitigation credits on insurance premiums. Sightline specifies impact-resistant windows from PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux by performance tier and price range, not by margin; the measured survey notes existing frame depth, sill condition, and anchor accessibility, and the written quote reflects the exact SKU required.

Hurricane Impact Windows
Hurricane impact windows are impact-resistant units specifically rated for the design pressures assigned to Kendall’s exposure category, typically 50 to 70 PSF for single-story residences and higher for two-story structures near open terrain. You need these when your current windows carry no Miami-Dade Notice of Acceptance, when your insurance carrier requires HVHZ documentation, or when you’re replacing windows after storm damage. Sightline pulls permits through Miami-Dade County’s online portal, schedules inspections, and provides the product approval documentation your insurer or wind mitigation inspector will request; the photo record shows each window’s NOA label in place.

Single Hung Impact Windows
Single hung impact windows have a fixed upper sash and a lower sash that tilts inward for cleaning; they are the most common replacement unit in Kendall’s ranch-style and split-level homes built between 1965 and 1995. You need these when your existing single hungs show seal failure (fogging between panes), when the balance system no longer holds the sash open, or when you’re converting non-impact units to HVHZ-rated replacements. Sightline measures the daylight opening to 1/8 inch, checks the existing frame for square, and specifies either pocket installation or full-frame replacement based on what the measured survey finds; the written price accounts for both scenarios before you commit.

Double Hung Impact Windows
Double hung impact windows allow both sashes to operate, providing superior ventilation control for Kendall’s cross-breeze-oriented floor plans and easier cleaning from inside for second-story openings. You need these when you want operable upper ventilation without exterior ladder access, when you’re matching the aesthetic of existing double hungs in a partial replacement, or when code requires egress operation in bedrooms. Sightline stocks double hung configurations from PGT and ViewLux with specific sill adapters for Kendall’s common 3-1/4 inch and 4-9/16 inch frame depths; the measured survey documents which adapter set applies, and the quote reflects it.

Horizontal Roller & Sliding Impact Windows
Horizontal roller impact windows operate on a horizontal track, making them ideal for wide openings, patio-facing walls, and rooms where a projecting sash would obstruct furniture placement or walkway clearance. In Kendall, we install these frequently in homes backing onto canal easements or golf course commons where the view width matters and the opening exceeds 48 inches. Sightline specifies roller systems from CGI and ES Windows with stainless steel tandem rollers rated for the sash weight; the measured survey checks the header deflection history, particularly in homes where the original slider has been operating out of square for years.

Vinyl Impact Windows
Vinyl impact windows use PVC-U frames with internal aluminum or steel reinforcement, offering thermal performance and corrosion resistance at a lower price point than aluminum or fiberglass alternatives. You need these when your priority is energy efficiency (vinyl frames typically achieve lower U-factors than thermally broken aluminum), when you’re replacing steel windows with active rust, or when budget constraints favor material savings without sacrificing impact rating. Sightline sources vinyl impact lines from ECO Window Systems and CWS with specific attention to Kendall’s sun exposure patterns; the measured survey notes southern and western elevations where darker frame colors may exceed vinyl heat deflection limits, and we spec accordingly.

Brands We Service for Impact Windows & Doors

We’ve installed and serviced PGT impact windows and doors across hundreds of Kendall openings since 2012, from their WinGuard aluminum line to their EnergyVue vinyl systems. We stock PGT’s common sash balances, roller assemblies, and glazing bead profiles, and we maintain current NOA documentation for every product we quote. Therma-Tru entry door systems with impact-rated sidelites and transoms are another core line; we’ve fitted their Classic-Craft and Fiber-Classic collections into Kendall homes where the original wood door had rotted at the sill or where the homeowner needed a full impact-rated entry assembly for wind mitigation credit. ViewLux architectural windows, including their geometric and custom shapes, round out our impact offerings for openings that standard rectangles won’t serve.
Whether you have PGT, Therma-Tru, ViewLux, or any other make, we can help. Our measured survey identifies the manufacturer, the series, and the approximate install date from frame markings and hardware profiles; if the original installer left no documentation, we reverse-engineer the specification from the physical evidence. The written quote names the exact replacement or repair scope, and the photo record confirms what was found versus what was done.

AfterSigns You Need Impact Windows & Doors Right Now
- Visible cracks or chips in the glass compromise the laminated interlayer that gives impact glass its structural integrity. Even a small chip at the edge can propagate under thermal stress or pressure cycling, and in Kendall’s afternoon thunderstorm pattern, a compromised unit may fail when the next storm loads it. We document edge damage in the measured survey and specify replacement before the next hurricane season.
- Fogging or moisture between panes means the insulated glass unit’s seal has failed, which also indicates the desiccant is saturated and the unit will soon show mineral staining. In impact-rated IGUs, seal failure is more serious than in standard windows because the laminated outer lite may still appear intact while the thermal and structural performance has degraded. Sightline’s survey includes a dew-point check to confirm whether the fog is interior condensation or seal failure.
- Difficulty opening, closing, or locking often tracks to frame racking, sill settlement, or hardware wear that will worsen until the window becomes inoperable. In Kendall’s Snapper Creek and Kendale Lakes areas, we’ve measured frame shifts of 3/8 inch or more in homes where the original installation didn’t account for soil movement; the sash is now binding because the frame is no longer square.
- Water intrusion during heavy rain indicates failed perimeter sealant, compromised glazing tape, or improper sill pan flashing from the original install. Kendall’s driving rain events, particularly on eastern exposures during summer thunderstorms, will find any gap; we trace the water path in the measured survey and specify the repair scope, whether it’s sealant replacement or full-frame reinstallation with proper sill pan integration.
- No Miami-Dade Notice of Acceptance or HVHZ rating means your current windows won’t qualify for wind mitigation insurance discounts and may not meet code for replacement or addition projects. We see this frequently in Kendall homes where previous owners installed “hurricane-resistant” products from out-of-state manufacturers without Florida product approval. Sightline verifies the NOA status during the measured survey and specifies only approved products for replacement.
Our Impact Windows & Doors Process - Step by Step

- 1
Measured survey and documentation. Our technician arrives at the scheduled time, identified by name and license number per Haven Clause 3. We measure every opening to 1/8 inch, check frame plumb and square with a laser level, photograph existing conditions, and note manufacturer markings if visible. You keep the measured survey; it becomes the basis for the written quote and the installation scope.
- 2
Written quote with product specification. Within 24 hours, you receive a written quote naming the exact product line, series, size, glazing specification, and hardware finish. The price is fixed; Haven Clause 1 means the measurement and the quote are the same document. For Kendall permit requirements, we include the NOA number, the design pressure rating, and the installation method.
- 3
Permit application and scheduling. Sightline pulls permits through Miami-Dade County’s online portal; most Kendall residential window replacements qualify for express review. We schedule installation once the permit is issued and the product is received from the manufacturer, typically 4-6 weeks for standard sizes and 8-10 weeks for custom geometries.
- 4
Installation with photo documentation. The crew arrives with the written scope, the measured survey, and the specified products. We remove existing units, prepare openings, install per the manufacturer’s NOA and Miami-Dade code, flash and seal per the Haven Standard, and photograph each stage. The photo record is uploaded to your job file before we leave.
- 5
Inspection, walkthrough, and warranty activation. We schedule the county inspection, meet the inspector on site, and walk you through the completed work. The 365-Day Done Right Promise is activated automatically; if anything is not done right, we make it right. You receive the final documented photo record, the inspection pass documentation, and the warranty terms in writing.
How Much Does Impact Windows & Doors Cost in Kendall?
A typical single hung impact window replacement in Kendall runs $890-$1,450 per opening for standard sizes up to 40 x 54 inches, using vinyl frame construction and standard laminated glass. Double hung impact windows in the same size range typically run $1,100-$1,750; the premium reflects the dual-operable sash hardware and the more complex balance system. Horizontal roller impact windows for larger openings, 60 to 96 inches wide, generally run $1,400-$2,400 depending on the number of panels, the roller hardware specification, and whether the installation requires header reinforcement. Full-frame replacement, as opposed to pocket installation, adds $200-$400 per opening for frame removal, sill preparation, and interior trim restoration.
Several factors move the price within these ranges. Frame material is the largest: vinyl typically costs 15-25% less than thermally broken aluminum, and fiberglass falls between the two. Glazing options, including low-E coatings, argon fill, and laminated thickness for higher design pressures, add incrementally. Installation complexity matters: second-story openings requiring scaffolding or interior protection, stucco or EIFS exterior finishes requiring careful cutting and matching, and homes with active termite damage or rot in the rough opening all require additional scope that the measured survey identifies before pricing.
To avoid overpaying, get the written quote in product-specific terms, not generic “impact window” language. A quote that names a manufacturer, series, and NOA number can be compared; one that doesn’t cannot. Sightline provides the measured survey for free and will review any competitor’s written estimate at no charge under our Free Second Opinion policy. The quote we provide includes the product, the installation method, the permit and inspection fees, and the disposal of existing units; there are no change orders unless you alter the scope after acceptance.

Frequently Asked Questions - Impact Windows & Doors in Kendall

Impact windows and doors are assemblies with laminated glass and reinforced frames tested to withstand missile impact and cyclic wind pressure per Miami-Dade County protocol. In Kendall, which lies within the High-Velocity Hurricane Zone, impact-rated products are required for new construction and most replacements, and they qualify for wind mitigation insurance discounts even on older homes. Call (786) 321-3319 to schedule a measured survey; we’ll verify whether your current products carry the required NOA and specify what replacement or upgrade is needed.
A typical full-home replacement of 10-15 openings in Kendall takes 2-3 days of on-site work once materials are on hand, with permit and inspection scheduling adding 1-2 weeks to the overall timeline. Custom or geometric windows, and jobs requiring full-frame replacement with stucco restoration, may extend to 4-5 days. The measured survey identifies which scenario applies, and the written quote includes the expected schedule before you commit.
Most Kendall homeowners invest $12,000-$28,000 for full-home impact window and door replacement, with per-opening costs ranging from $890 for standard single hungs to $2,400 for large horizontal rollers or custom configurations. The measured survey determines your exact count, sizes, and installation method; the written quote reflects those specifics with no change orders. Call (786) 321-3319 for your free measured survey and written estimate.
Yes. We install and service PGT, Therma-Tru, ViewLux, and products from all eight manufacturer lines we carry: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Our measured survey identifies your existing manufacturer and series from frame markings and hardware profiles; we stock common repair components and can source OEM parts for warranty or out-of-warranty service. Bring us any competitor’s written estimate and we’ll review it at no charge.
We do not offer same-day installation for planned impact window and door projects; these are engineered products with manufacturer lead times and permit requirements that make immediate installation impossible. For storm damage requiring emergency board-up or temporary protection, our 24/7 live phone coverage can dispatch a crew to secure the opening; the permanent impact-rated replacement follows the standard measured survey and permitting process. Call (786) 321-3319 at any hour to report damage and arrange temporary protection.
Every installation is covered by Sightline’s 365-Day Done Right Promise, written into the Haven Standard: if it’s not done right, we make it right. Manufacturer warranties on the product itself vary by line, PGT’s lifetime limited warranty on vinyl frames, for example, and we pass through the full terms in writing. The photo record and the written scope are your documentation; both are provided at completion.
Clear a 3-foot workspace around each interior opening, remove window treatments and wall hangings near the work area, and secure pets in a separate room. Our crew brings drop cloths, HEPA vacuums, and interior protection as standard; the measured survey notes any furniture that must be moved and whether specialty protection is needed for flooring or electronics. We’ll confirm preparation specifics when we schedule installation, and the written scope includes any homeowner responsibilities before work begins.
