Whole-house hurricane protection costs $10,000 to $30,000. Most homeowners cannot write that check at once. The good news is that phasing your installation intelligently gets you meaningful protection now, at a cost you can manage, without paying a premium for doing it in stages.
The Core Principle: Protect the Most Vulnerable First
A hurricane does not care whether 80% of your windows have shutters. It will find the 20% that don't. Phased installation works when you prioritize ruthlessly — protecting the openings most likely to fail and cause catastrophic damage before working toward whole-house coverage.
The hierarchy of vulnerability:
- Garage door — the single largest and weakest opening on most homes. A failed garage door can cause the roof to lift. Protect this first regardless of anything else.
- Sliding glass doors and large picture windows — large glazed openings fail earlier under wind pressure than small windows and allow massive water intrusion when they do.
- Primary exposure facades — the sides of your home facing south and east (Atlantic coast) or south and west (Gulf coast) take the most direct wind load. Protect these faces before protected unexposed sides.
- Entry doors — exterior doors without reinforcement can fail and allow rapid pressurization of the interior. Hurricane-rated door hardware is inexpensive relative to shutters.
- Remaining windows — smaller windows on protected facades last.
A Practical 2–3 Year Phasing Plan
| Phase | What to Protect | Typical Cost | Protection Level |
|---|---|---|---|
| Year 1 | Garage door + all sliding glass doors + largest picture windows | $3,000–$8,000 | 60–70% of risk eliminated |
| Year 2 | All remaining windows on primary exposure facade(s) | $3,000–$6,000 | 85–90% of risk eliminated |
| Year 3 | Remaining windows on protected facades + lanai/patio | $2,000–$5,000 | 100% coverage |
This plan delivers most of the safety benefit in Year 1 at roughly one-third the whole-house cost, then systematically closes the remaining gaps over two additional seasons — each at a manageable spend.
How Phasing Affects Permits and Cost
Each phase requires its own building permit. This adds $150–$400 in permit fees per phase compared to a single whole-house permit — but that premium is far smaller than the carrying cost of financing the entire job in year one.
To minimize the permit cost penalty of phasing:
- Tell your contractor you plan to phase when getting the initial quote — they can design the first permit to reference the planned future phases, which streamlines subsequent permits
- Use the same contractor across phases — they already have your home's measurements, product approval numbers, and permit history, reducing their overhead on phases 2 and 3
- Group openings by facade or room rather than doing scattered individual windows — permits and installation are more efficient by area
Insurance Implications of Partial Protection
Partial protection creates a nuanced insurance situation. Here is what to expect:
- Partial credit is possible — some insurers offer partial wind mitigation credits for partial opening protection. The specific credit depends on which openings are protected and your insurer's scoring model.
- Full credit requires all openings — most insurers' maximum wind mitigation discount requires all openings to be protected. Partial protection gets a partial discount.
- Get a wind mitigation inspection after each phase — document each phase's completed work and submit an updated report to your insurer. Each phase should increase your discount.
- Do not wait for 100% to file — the partial discount from Phase 1 may partially offset the cost of Phase 2.

Keep Products Consistent Across Phases
The most important planning decision for a phased installation is product consistency. Using the same product across all phases:
- Simplifies the permit process — the same FL approval covers all phases
- Gives a uniform appearance to the finished home
- Simplifies maintenance — one system to service and repair
- Allows the contractor to order track and hardware in bulk, reducing per-unit material cost
Decide on your product (accordion, roll-down, storm panels) in Year 1 and commit to it for the entire phased plan. Mixing products across phases creates complexity and higher long-term maintenance cost.
Frequently Asked Questions
Is partial protection better than no protection?
Absolutely — protecting 60% of your openings eliminates most of the catastrophic failure scenarios. The goal of phasing is to get meaningful protection in place now while working toward whole-house coverage. An unprotected home is far more vulnerable than a partially protected one.
Can I mix storm panels in year one with accordion shutters in later years?
You can — and many homeowners do this to reduce Year 1 costs. Storm panels on the largest openings provide immediate protection at lower cost. Accordion shutters on remaining openings in later phases give you permanent protection without deployment burden. The two systems can coexist on the same home. The downside is two different systems to maintain and operate.
Will my contractor give me a better price if I commit to all phases upfront?
Often yes — a contractor who knows they have a 3-year relationship with a customer will sometimes discount Year 1 work in exchange for the committed future business. Get this in writing — a letter of intent or a phased project agreement specifying the planned scope of each phase and approximate pricing. This protects both you and the contractor.
