Impact Windows & Doors in Westwood Lake, FL: Timeline, Cost, and What to Expect
Impact windows and doors in Westwood Lake typically run $8,000-$25,000 for a full-home installation, with most projects completed in 2-4 weeks from permit approval. Because Westwood Lake homes are overwhelmingly pre-1992 CBS construction with original non-impact openings, nearly every job here includes structural tie-down retrofits and Miami-Dade NOA-approved products that out-of-county crews often miss.

How We Handle Impact Windows & Doors From First Measurement to Final Inspection
We’ve learned that Westwood Lake jobs go smoother when homeowners know exactly when they’re needed for decisions. Here’s how we stage it.
Stage 1: On-site assessment and NOA verification (Day 1)
We measure every opening, photograph existing conditions, and check whether your current frames are wood, aluminum, or vinyl. This matters because pre-Andrew CBS homes in Westwood Lake often have original wood frames rotted at the sill from decades of Everglades-margin humidity. We also verify that your selected product lines carry current Miami-Dade Notice of Acceptance approval - not just Florida Building Code compliance, but the county-specific NOA that inspectors here enforce. You’ll decide: full-frame replacement or insert retrofit, and whether to upgrade to laminated insulated glass versus monolithic impact glass. We leave with signed specs and a deposit.
Stage 2: Engineering and permit submission (Days 2-10)
Our drawings go to Miami-Dade County building department, not a city office - Westwood Lake is unincorporated, so there’s no municipal shortcut. For homes needing structural tie-downs or roof-to-wall connector upgrades to meet current wind-load standards, we coordinate with a Florida-licensed structural engineer. This adds 3-5 days but prevents inspection failures. You approve any engineering addendum before we file.
Stage 3: Product procurement and staging (Days 11-20)
Impact-rated windows and doors from Andersen, PGT, or CGI don’t sit on shelves; they’re built to order with NOA-mandated hardware and missile-impact certification labels. Lead times run 2-3 weeks for standard sizes, 4-5 weeks for custom architectural shapes. We stage materials at our Fort Lauderdale warehouse and coordinate delivery to your driveway the day before install. You’ll get a 48-hour delivery confirmation.
Stage 4: Installation and structural integration (Days 21-28, weather permitting)
Crews remove existing units, install new flashed and anchored frames with Miami-Dade-approved fastening patterns, and seal with polyurethane foam and backer rod per manufacturer specs. On Westwood Lake’s 1960s-70s CBS ranches, we frequently find roof deck edges that need reinforcement before the new window header can carry wind uplift. We handle this in-house rather than stopping for a separate roofer. Daily cleanup; your home is secured each night.
Stage 5: County inspection and final walkthrough (Days 29-35)
Miami-Dade sends a building inspector to verify NOA labels, fastening schedules, and operability. We pass roughly 90% on first visit because we pre-verify everything. Final walkthrough with you: operation, cleaning, warranty registration. You get a binder with product warranties, NOA documentation, and inspection sign-off.
The Impact Windows & Doors Choices That Actually Change Your Price and Performance
- Frame material: aluminum versus vinyl versus wood-clad. Aluminum dominates South Florida impact work for structural strength and narrow sightlines, but it conducts heat and needs thermal breaks to meet energy code. Vinyl costs 15-20% less and insulates better, yet bulkier frames reduce glass area. Wood-clad (Andersen E-Series, for example) offers the best interior aesthetics but requires diligent maintenance in Westwood Lake’s saturated humidity. Most homeowners here choose aluminum with a thermal break or high-grade vinyl.
- Impact glass type: monolithic laminated versus laminated insulated. Monolithic is a single laminated lite - meets code, blocks wind-borne debris, costs less. Laminated insulated adds an interior air gap and Low-E coating, cutting cooling loads significantly. In Westwood Lake’s unshaded ranch homes with western exposure, the upgrade pays for itself in 4-6 years of FPL bills. Expect a $2,500-$5,000 premium for full-home insulated glass.
- Opening style: single-hung, horizontal roller, or casement. Single-hung is cheapest and most common for replacement. Horizontal rollers suit wide openings and meet egress requirements with less frame intrusion. Casements seal tightest against wind-driven rain - relevant where Westwood Lake’s low-slope roofs dump runoff against window heads. Each style has different NOA listings; not every product line offers every configuration.
- Door configuration: single entry, French, or sliding glass. Impact-rated sliding glass doors in Westwood Lake often replace 1970s aluminum sliders that leak during summer thunderstorms. French doors look substantial but need more wall space for swing clearance. We size rough openings to your existing or discuss widening - a structural decision that affects permit scope and cost.
- Hardware and finish: standard white, bronze, or custom color. Standard finishes ship faster. Custom powder-coating adds 2-3 weeks and $800-$1,500. We don’t upsell it unless you’re matching existing trim or HOA requirements.
These choices are part of a full Windows & Doors in Westwood Lake project, or we can isolate impact protection as a standalone scope.
What Impact Windows & Doors Costs in Westwood Lake, FL
| Project Scope | Typical Range |
|---|---|
| Partial impact upgrade (front elevation + main entry) | $8,000 - $14,000 |
| Full-home impact windows and doors, standard sizes | $14,000 - $22,000 |
| Full-home with custom shapes, insulated glass, and hardware upgrades | $20,000 - $25,000 |
Five variables push you toward the high or low end:
1. Existing frame condition. Wood frames with rot at the sill require full-frame replacement and stucco repair - add $400-$800 per opening. Insert retrofits into sound aluminum frames cost less but reduce glass size.
2. Structural tie-down requirements. Pre-1992 CBS homes without hurricane straps need roof-to-wall connectors and often roof deck edge reinforcement. Engineering and labor add $1,500-$4,000 depending on roof complexity.
3. Glass specification. Monolithic laminated versus insulated laminated is the biggest single material swing, typically $2,500-$5,000 across a whole house.
4. Permit and inspection scope. Miami-Dade County’s NOA verification and structural engineering for wind-load compliance add $800-$1,500 in fees and professional services. Out-of-county contractors who miss this get red-tagged and pass costs to you.
5. Access and protection. Homes with dense landscaping against openings, interior floor protection for occupied jobs, or security requirements add labor hours. Westwood Lake’s mature ficus hedges and narrow side yards are common obstacles.
A written estimate from us includes: all products with NOA numbers, demolition and disposal, rough carpentry and structural work as needed, flashing and sealing, permit fees, and county inspection coordination. It does not include: interior trim painting (we install primed wood or PVC, you paint), stucco color matching (we patch with base coat, finish coat by your painter), or landscaping repair.
Why Westwood Lake Homes Make Impact Windows & Doors a Different Job
Westwood Lake sits where Miami’s urban grid dissolves into the historic Everglades margin, and that geography changes everything about construction here. The water table is exceptionally high and unpredictable - we’ve hit standing water digging footings for window seats that would be dry two blocks east. More critically for impact openings, the neighborhood’s housing stock is overwhelmingly 1960s and 1970s CBS ranch homes built before Hurricane Andrew rewrote Florida’s building code. These houses have solid masonry walls but original wood-frame roof systems, no hurricane straps, and aging flat or low-slope roofs that pond water against window heads.
What this means practically: when our Windows & Doors crew arrives at a Westwood Lake job, we’re rarely just swapping glass. We’re integrating new impact-rated openings into walls that were never designed for modern wind loads, often while water management issues demand attention at the same rough opening. The Miami-Dade County building department enforces this strictly through the NOA product-approval system - a layer beyond state code that many contractors from Broward or Palm Beach counties don’t anticipate. We’ve seen jobs stall for weeks because a previous installer specified impact products with Florida Product Approval but not Miami-Dade NOA. We source Andersen, PGT, and CGI lines specifically for their current NOA listings, and we pre-verify every label before delivery.
Homeowners in Westwood Lake often pair exterior hardening with property-line security upgrades - Aluminum Fence in Westwood Lake and Iron Fence in Westwood Lake are common companion projects we coordinate under the same permit timeline when it makes sense.
Our coverage area includes all of Westwood Lake and surrounding unincorporated Miami-Dade, with project experience on the CBS ranches near SW 40th Street and the low-slope roof clusters closer to Bird Road.

Frequently Asked - Impact Windows & Doors in Westwood Lake
From permit approval to final inspection, most Westwood Lake homes take 2-4 weeks. Pre-1992 CBS homes needing structural tie-downs add 3-5 days. Product lead times are typically the longest variable - 2-3 weeks for standard sizes, 4-5 weeks for custom. Call (844) 665-0162 and we’ll check current lead times for your specifications.
Yes. Westwood Lake is unincorporated Miami-Dade County, so permits run through the county building department, not a city office. Every impact product must carry a current Miami-Dade Notice of Acceptance (NOA), not just Florida Product Approval. We handle permit drawings, engineering if needed, and inspection scheduling. The permit fee is included in our written estimate.
Usually yes. Impact window replacement is primarily an exterior envelope job; we work within existing rough openings. The exception is when homeowners want to widen openings for larger doors or reconfigure rooms - then we coordinate electrical and plumbing relocation as a separate scope. We flag this during the Day 1 assessment so you’re not surprised.
Repairing non-impact windows - reglazing, new balances, weatherstripping - runs $200-$600 per unit but leaves you without hurricane protection or modern energy performance. Full impact replacement in Westwood Lake starts around $8,000 for partial elevations and delivers code compliance, insurance discounts, and structural integration. For pre-Andrew homes, repair is rarely the better long-term investment.
Product warranties vary by manufacturer: Andersen offers 20 years on glass and 10 years on non-glass components; PGT and CGI carry limited lifetime on vinyl frames with 10-year glass coverage. Our installation workmanship is warranted for 5 years. We register all warranties with the manufacturer and provide documentation at final walkthrough. Specific terms depend on the product line you select.
