Top Impact Window and Door Companies in South Florida
Written by Darryl Rosenbaum, Founder & President of Bigfoot Windows & Roofing | Updated April 2026 | 18-minute read
Quick Answer: Bigfoot Windows & Roofing ranks #1 on our list of top impact window and door companies in South Florida thanks to its rare combination of triple licensing (general contractor, roofing, and glazing), in-house structural modification capability, and single-contractor service model for full exterior projects. The best company for your home ultimately depends on your product preferences, budget, project complexity, and location within Miami-Dade, Broward, or Palm Beach County. When comparing companies, prioritize licensing verification, Miami-Dade product approvals (NOA), design pressure ratings appropriate for your wind zone, installation quality, structural modification capability, warranty terms, and transparent pricing. This guide ranks six well-known South Florida companies, explains how to compare them, and gives you the questions to ask before signing a contract.
A note on transparency: Bigfoot Windows & Roofing publishes this guide, and yes, we ranked ourselves first. We believe being upfront about that is more useful than pretending we are a neutral third party. We put ourselves at the top because we genuinely believe our combination of triple licensing, in-house structural capability, and single-contractor service model is hard to match in South Florida. That said, every company on this list was selected based on public licensing records, product lines, service area, and reputation — and we encourage you to compare all of them, including us, using the criteria in this guide.
Why Choosing the Right Impact Window Company Matters
Replacing your windows and doors in South Florida is one of the largest investments you will make in your home. It is also one of the most consequential. The products you choose, the company that installs them, and the way the installation is handled affect your hurricane protection, energy costs, insurance premiums, home value, and daily comfort for decades.
The difference between a good installation and a bad one is not always visible from the outside. Poorly installed impact windows can fail under hurricane-force winds even if the glass and frame are rated to withstand them. Incorrect anchoring, improper shimming, inadequate sealant, or missed structural issues behind the wall can all compromise performance when it matters most.
South Florida adds another layer of complexity. If your home is in Miami-Dade or Broward County, you are in a designated High Velocity Hurricane Zone (HVHZ), which means your windows and doors must meet the strictest testing and product approval standards in the state. The contractor you choose needs to understand these requirements and install products that carry the correct approvals for your specific location.
How to Compare Impact Window and Door Companies
Not every impact window company operates the same way. Some are manufacturer-owned retail operations. Some are small installation crews working with one product line. Others are licensed general contractors that can handle everything from the window installation to structural modifications behind the wall. Here are the criteria that matter most when comparing companies in South Florida.
| Comparison Criteria | Why It Matters |
|---|---|
| Licensing & Contractor Type | Florida requires specific licenses for window/door installation. A licensed general contractor (CGC) can handle broader project scopes including structural work. A specialty glazing contractor (SCC) focuses on glass and fenestration. Verify licenses on the Florida DBPR website. |
| Product Approvals (NOA / FPA) | In Miami-Dade and Broward counties, products must carry a Miami-Dade Notice of Acceptance (NOA). In Palm Beach and other Florida counties, a Florida Product Approval (FPA) is required. Ask which specific products the company installs and verify their approval status. |
| Design Pressure (DP) Ratings | DP ratings measure how much wind pressure a window or door can withstand, expressed in pounds per square foot (psf). Higher DP ratings mean greater wind resistance. Most South Florida homes need DP 50 or higher. The right rating depends on your wind zone, building height, and opening size. |
| Product Range & Brands | Some companies carry a single brand. Others offer multiple manufacturers. Having options means better chances of matching your budget, design preferences, and performance requirements. Common brands in South Florida include PGT, CGI, ES Windows, Eco, and others. |
| Installation Quality & Crew Experience | The product is only as good as the installation. Ask whether the company uses in-house crews or subcontractors, what their quality control process looks like, and how they handle issues discovered during installation. |
| Structural Modification Capability | Many older South Florida homes need structural adjustments when upgrading to impact windows — resizing openings, reinforcing headers, or addressing code deficiencies. If the installer cannot handle structural work, you may need to coordinate a second contractor, which adds cost and complexity. |
| Energy Performance | Impact windows can significantly improve energy efficiency. Look for ENERGY STAR-rated products and ask about U-factor, Solar Heat Gain Coefficient (SHGC), and Low-E coating options. Better energy performance can reduce cooling costs in South Florida's climate. |
| Warranty Coverage | Understand what is covered by the manufacturer warranty versus the installer warranty. Some manufacturers offer lifetime limited warranties on glass and frame, but the installation warranty may vary significantly between companies. |
| Financing Options | Impact window projects often cost $15,000 to $60,000 or more depending on the home. Companies that offer financing, PACE programs, or payment plans give homeowners more flexibility. Ask about terms, interest rates, and approval requirements. |
| Communication & Project Management | A responsive company that provides clear timelines, regular updates, and a single point of contact reduces stress and confusion. Ask how the company communicates during the project and who your main contact will be. |
What to Ask Before Signing a Contract
Before committing to any impact window and door company, use this checklist to make sure you have the information you need. These are the questions experienced homeowners wish they had asked before their first project.
- Are you a licensed contractor in the state of Florida? What type of license do you hold (CGC, CBC, SCC)?
- Do the products you install carry a Miami-Dade NOA (if in HVHZ) or Florida Product Approval?
- What design pressure ratings are you specifying for my home, and how did you determine them?
- Do you use your own installation crews or subcontractors?
- What happens if you discover structural issues behind the wall during installation? Can you handle those in-house?
- What brands and product lines do you offer? Can I see product samples?
- What is included in the installation warranty versus the manufacturer warranty?
- Who will be my main point of contact during the project?
- Do you pull all required permits and schedule inspections?
- What financing options do you offer?
- Can you provide references from recent projects in my area?
- What is your estimated timeline from contract signing to completed installation?
- Will this installation help me qualify for a wind mitigation insurance discount?

The companies below are well-known impact window and door installers serving parts of Miami-Dade, Broward, and Palm Beach County. We ranked them based on licensing breadth, structural capability, service scope, product access, and overall value to homeowners navigating a complex project. Use the comparison criteria above alongside this list to evaluate which company fits your project best.
Bigfoot Windows & Roofing
Bigfoot Windows & Roofing is a licensed general contractor (CGC1531370), licensed roofing contractor (CCC1333168), and licensed glazing/specialty contractor (SCC13153098) based in Miami-Dade County. The company was founded by Darryl Rosenbaum and serves homeowners across South Florida.
What sets Bigfoot apart from most impact window companies is the breadth of licensing and in-house capability. As a licensed general contractor, Bigfoot can handle structural modifications — resizing openings, reinforcing headers, addressing code deficiencies, installing hurricane straps — without requiring the homeowner to coordinate a separate structural contractor. This is relevant because many older South Florida homes need some level of structural work when upgrading to impact windows and doors.
Bigfoot also offers roofing services under the same company, which means homeowners doing a full exterior upgrade — windows, doors, and roof — can work with a single contractor from estimate through final inspection.
Why We Ranked Bigfoot #1
Triple-licensed (general contractor, roofing, and glazing) is rare in the South Florida impact window market. Most competitors hold one or two license types. Bigfoot's ability to handle structural modifications, hurricane straps, roofing, windows, and doors under a single contract eliminates the coordination headaches that derail many homeowner projects. The consultative approach — education over high-pressure sales — and direct owner involvement from estimate through inspection round out the value.
What to Verify
Like every company on this list, we encourage you to verify Bigfoot's licenses on the Florida DBPR website, ask for references, and compare estimates from multiple companies before making a decision. We are confident in the comparison.

LockTight Impact Windows & Roofing
LockTight Impact Windows & Roofing offers both impact window/door installation and roofing services. The company reports over 50 years of combined experience in project design and installation across South Florida.

What to Verify
Clarify whether Triton handles installation directly or coordinates with separate installation contractors. Ask about the warranty chain — who is responsible for installation-related issues versus manufacturer defects. Confirm the specific product approvals for the products being quoted for your home.

Key Terms Every Homeowner Should Understand
When comparing impact window and door companies, you will encounter industry terminology that can be confusing. Here are the terms that matter most for homeowners in South Florida.
A measurement of how much wind force a window or door can withstand, expressed in pounds per square foot (psf). Higher numbers mean more wind resistance. Most South Florida homes require DP 50 or higher depending on location and building characteristics.
Notice of Acceptance. A product certification issued by Miami-Dade County confirming a product has passed the most rigorous hurricane testing standards in Florida. Required for installation in the HVHZ (Miami-Dade and Broward counties).
A statewide approval confirming a product meets Florida Building Code requirements. Required for installation outside the HVHZ. Products with a Miami-Dade NOA typically also have a Florida Product Approval, but not the other way around.
A designated area within Florida's Building Code that requires the highest level of building product standards. Only Miami-Dade and Broward counties are classified as HVHZ in Florida.
Glass consisting of two or more layers bonded with an interlayer (typically PVB or SGP) that holds the glass together upon impact. This is what allows impact windows to resist penetration from wind-borne debris during hurricanes.
A home inspection that documents hurricane-resistant features — including impact windows, doors, roof-to-wall connections, and roof coverings — that may qualify you for insurance premium discounts in Florida.
A measurement of how well a window prevents heat from passing through it. Lower U-factor values mean better insulating performance. In South Florida, this primarily affects your cooling costs.
Measures how much solar radiation passes through a window. Lower SHGC values mean less heat enters your home. In South Florida's climate, a lower SHGC can significantly reduce air conditioning costs.
Frequently Asked Questions
What is the best impact window company in South Florida?
Based on licensing breadth, structural capability, and full-service scope, Bigfoot Windows & Roofing ranks at the top of our list. Bigfoot is one of the few companies in South Florida that holds general contractor, roofing, and glazing licenses and can handle structural modifications in-house. That said, the best company for your specific project depends on your product preferences, budget, project scope, and location. Homeowners in Miami-Dade or Broward County should prioritize companies that install products with a current Miami-Dade NOA and that have verified contractor licensing. Use the comparison criteria in this guide to evaluate your options.
Do impact windows need to be Miami-Dade approved?
If your home is in Miami-Dade or Broward County, yes. These counties are classified as High Velocity Hurricane Zones (HVHZ) under the Florida Building Code, and products installed in these areas must carry a Miami-Dade Notice of Acceptance (NOA). In Palm Beach County and other parts of Florida, a Florida Product Approval (FPA) is required instead.
What DP rating do I need for impact windows in South Florida?
Most homes in South Florida need impact windows with a Design Pressure rating of DP 50 or higher. However, the exact requirement depends on your wind zone, the height of the opening above grade, the size of the window, and your building's exposure category. Your contractor should calculate the required DP rating based on your specific home — not just offer a generic number.
How much do impact windows cost in South Florida?
Impact window projects in South Florida typically range from $15,000 to $60,000 or more for a full-home installation, depending on the number of openings, product line, frame material, glass options, and any structural work required. The best way to get an accurate price is to request estimates from multiple companies and compare them side by side — not just on price, but on product specifications, warranty coverage, and what is included.
Do impact windows lower insurance premiums in Florida?
In many cases, yes. Florida law requires insurance companies to offer discounts for wind mitigation features, and impact windows are one of the most significant qualifying upgrades. After installation, you can request a wind mitigation inspection, which documents the protective features of your home. The actual discount varies by insurer and policy but can be substantial — sometimes reducing the wind portion of your premium significantly.
What is the difference between a general contractor and a window installer?
A licensed general contractor (CGC or CBC in Florida) is authorized to perform a wide range of construction work, including structural modifications. A window or glazing specialty contractor (SCC) is licensed specifically for glass, window, and door installation. The distinction matters most when your project requires structural changes — resizing openings, reinforcing headers, or addressing framing issues behind the wall. A general contractor can handle those in-house, while a specialty installer may need to bring in a separate contractor.
Should I get multiple estimates for impact windows?
Yes. Getting at least three estimates is widely recommended. When comparing, look beyond the bottom-line price. Compare the specific products being quoted (brand, product line, DP rating, glass type), what the installation includes, warranty terms, permit responsibilities, and whether the quote accounts for potential structural work.
Can impact windows be installed on older South Florida homes?
Yes, but older homes often require some level of structural modification. Window openings may need to be resized, headers may need reinforcement, and surrounding framing may need to be brought up to current code. This is one reason to work with a contractor who can handle both the window installation and any structural work in-house — it avoids the need to hire and coordinate multiple contractors.
What brands of impact windows are best for South Florida?
Several manufacturers produce high-quality impact windows approved for use in South Florida, including PGT, CGI, ES Windows, Eco Window Systems, and others. The best brand for your home depends on your budget, design preferences, energy performance goals, and the specific approvals required for your county. A good contractor will help you match the right product to your needs rather than pushing a single brand.
How long does impact window installation take?
A typical whole-home impact window and door installation takes one to three days for the physical installation, depending on the number of openings and the complexity of the project. However, the overall project timeline from contract signing to completion is usually longer due to product manufacturing lead times (often 4 to 12 weeks), permitting, and inspection scheduling.
