Why Our Quotes Cost More — What You’re Actually Paying For

The Real Question

Why Does One Quote Look So Different From Another?

Two quotes for the same window count can vary by 30–40%. Here is why that gap is almost never about profit margin.

You asked three contractors for an impact window quote. The numbers came back spread across a wide range — and the lowest bidder said the others are just overcharging, while the highest bidder said the lowest is cutting corners. You have no way to tell who is right — because both might be.

The core problem is that quotes in South Florida’s window and door market are not standardized. One contractor might include pulling the building permit; another assumes you will handle it yourself. One includes a structural inspection of the rough opening; another does not look at header conditions at all. One carries workmanship warranty in writing; another carries nothing after they leave your driveway.

When you subtract those line items, the “expensive” quote sometimes becomes the cheaper one. This article breaks down exactly what our quotes include and why — so you can ask every contractor the same questions before you choose.

South Florida Context

Miami-Dade and Broward Have Different Rules Than the Rest of Florida

Miami-Dade and Broward counties fall inside Florida’s High-Velocity Hurricane Zone (HVHZ) — the strictest residential building code jurisdiction in the United States. Impact window installations here require a permit, a licensed contractor of record, a Miami-Dade Notice of Acceptance (NOA) for every product installed, and a final inspection sign-off by the building department.

A product with a current Florida Product Approval (FL number) that covers HVHZ use is legal to install in Miami-Dade and Broward. A Miami-Dade NOA is an additional certification some products also carry; it is not required for the permit. Any contractor who installs windows in Miami-Dade without pulling a permit and using NOA-certified products is exposing you to a failed inspection, a stop-work order, and potential forced removal of the work at your expense.

That compliance overhead — permit fees, NOA-certified product procurement, a licensed contractor of record — costs real money. It is visible in the quote. What you do not see in a low-ball proposal is the liability you absorb when those steps are skipped. You can also explore our full impact window service options to understand what a compliant South Florida installation involves from start to finish.

What the Price Actually Covers

The Six Line Items Most Low Quotes Leave Out

Here is a plain-English breakdown of what separates a complete proposal from a stripped-down one. Run through this list with every contractor you interview.

A contractor who excludes permits saves real money in direct costs — but shifts that liability entirely onto you. Unpermitted impact window work can surface at resale when a buyer’s attorney orders a permit history report, and it can void your homeowner’s insurance claim after a storm event.

Side-by-Side Comparison

Permitted vs. Unpermitted Installation — What Changes

When the Other Contractor Might Be the Better Fit

If a competitor carries the same NOA-certified products, pulls permits as standard practice, holds a comparable licensed-contractor-of-record on each job, and provides a written workmanship warranty — and their number is still lower — that is a legitimate competitive price difference worth exploring. Bigfoot does not claim to be the lowest price in South Florida. We claim our price reflects what a complete, code-compliant installation actually costs. If another contractor demonstrates the same completeness at a lower number, they may be a genuine fit for your project.

What We Actually Install

Products That Pass HVHZ Inspection — The First Time

Bigfoot installs Mr. Glass impact windows and doors as our primary window and door line. All Mr. Glass series carry Florida Product Approval. The Mr. Glass 2500T thermally broken impact door holds a Miami-Dade Notice of Acceptance (NOA) — a requirement for any door installation in Miami-Dade and Broward counties.

For frame material, we recommend aluminum. Aluminum has a longer track record than vinyl in South Florida’s HVHZ heat, UV, and coastal salt-air conditions. Where energy efficiency is a priority, thermally broken aluminum frames add a thermal barrier without sacrificing the corrosion resistance aluminum provides in coastal environments.

On glass, our standard recommendation is SB 70 Low-E. For whole-house replacement projects, we offer Cardinal ClimateGuard 6227 — which carries equivalent specifications to SB 70 — as a complimentary upgrade. If your property is within two miles of saltwater, note that specifying a 2604 wood-grain frame finish voids the manufacturer’s 10-year product warranty; the correct coastal-zone spec is the 2605 finish.

These product choices are not marketing preferences. They are driven by what passes Miami-Dade HVHZ inspection and what holds up in a coastal environment over a 20-plus-year product life. You can review our impact window pricing estimator to see how product choices affect the installed cost range.

The GC Advantage

Structural Scope — Handled In-House, Not Escalated to a Second Contractor

One of the most common mid-project surprises in impact window installations is a structural discovery: a header that is undersized for the new opening, or hurricane straps that are absent or corroded on an older home. When a specialty-only contractor makes this discovery, the project typically stalls while a general contractor is sourced, quoted, and scheduled — adding weeks and an unpredictable cost.

Bigfoot performs header resizing and hurricane strap upgrades as in-scope services under its Certified General Contractor license (CGC1531370). That means structural work can be completed under the same permit set, by the same crew, without a separate mobilization. This is a structural advantage grounded in license breadth — not a delivery-outcome promise, but a meaningful reduction in the coordination risk that mid-project structural findings create.

Learn more about how impact window installation works in Florida, including what triggers a structural assessment during the permitting phase.

Here is how the process flows from first call to final inspection:

1. Estimate: We walk the openings, note structural conditions, and produce a written proposal that includes permit costs and any structural scope we can anticipate.
2. Permit application: We pull the permit. You receive a copy. The NOA number for every product is filed with the application.
3. Structural prep (if needed): Header resizing or hurricane strap upgrades are completed before window installation begins — same permit, same crew.
4. Installation: Licensed installation crew. Products installed per the NOA specifications for fastener spacing and embedment.
5. Inspection: We schedule and attend the final building inspection. You receive a closed permit and a clean record.

Who We’re Not the Right Fit For

We believe you should know upfront when a different contractor will serve you better. Here are four situations where Bigfoot is genuinely not the best match:

• You need the absolute lowest number and permits are optional to you. If your primary goal is the lowest possible upfront cost and you are willing to accept the risk of unpermitted work, a specialty-only shop that does not pull permits will quote less than we do. We will not compete on that basis.
• Your project is outside our service area. We serve Miami-Dade, Broward, and Palm Beach counties. If your property is farther north or in a different region of Florida, a local contractor will know the specific municipal requirements better than we do.
• You are seeking a bid-and-match negotiation. Our proposals are itemized and priced based on what the work actually requires. We do not inflate quotes to create room for dramatic discounts. If you are looking for a contractor who will drop significantly on the spot to match a competitor, that is not how we operate.
• Your timeline requires installation within the next two weeks. HVHZ permit review in Miami-Dade typically takes two to six weeks for standard residential window replacement projects. If you have an imminent deadline, that timeline may not work for a fully permitted installation.
