Adding a lanai to your Florida home is one of the best ways to expand your living space into the outdoors. A well-built outdoor lanai gives you a screened, covered area where you can enjoy Florida’s weather year-round without the bugs, debris, and afternoon rain that make unprotected outdoor spaces difficult to use. But the quality of the finished product depends entirely on the contractor you choose to build it.
Before you sign a contract or put money down for lanai construction, you need to know what to ask a contractor and what the right answers look like. The questions below are the ones that separate a qualified, licensed lanai builder from one who is going to cost you time, money, and frustration down the road.
Commercial Residential Aluminum (CRA) has been building lanai enclosures, pool cages, and screen structures across Florida’s Gulf Coast since 1992. With over 200 team members and more than 30,000 screening projects completed in the last five years, CRA has answered every one of these questions thousands of times. Here is what you should be asking.
Here Is What to Ask a Contractor Before Building a Lanai
When you sit down with a lanai contractor for the first time, the conversation should cover far more than price. A lanai porch in Florida is a structural addition to your home that must meet the Florida Building Code, withstand the state’s storm seasons, and hold up against years of heat, humidity, and UV exposure. The questions below help you determine whether a contractor is equipped to handle all of that.
Are You Licensed and Insured in the State of Florida?
This is the first question to ask, and it is non-negotiable. Florida requires contractors performing structural work to hold a valid state license. A licensed contractor has demonstrated the skills and knowledge required to perform the work, and their license gives you a direct pathway to follow if problems arise. Ask for the contractor’s license number and verify it independently. CRA is a Florida State Licensed Contractor (Lic. SCC056736, CGC058897) and is fully insured to accommodate residential and commercial projects.
Working with an unlicensed contractor exposes you to safety hazards, poor-quality work, noncompliance with building codes, and potential liability if anyone is injured on the job site. If a contractor cannot produce current proof of both licensing and insurance, move on.
How Long Have You Been Building Lanais in Florida?
Experience in general contracting does not automatically translate to experience with lanai construction. Building a lanai porch in Florida requires specific knowledge of aluminum framing systems, screen materials, Florida’s wind-load requirements, and the permitting process that varies by county and municipality. Ask how many lanai projects the contractor has completed and whether they can show you examples of finished work in your area.
Who Handles Permitting and Engineering?
Building permits are required in all Florida counties for lanai enclosures. The permit process ensures that the structure complies with the Florida Building Code, including wind load and structural requirements for your specific location. Permit review and approval typically takes two to six weeks, depending on the complexity of the project and the workload of your local building department.
A qualified contractor handles the entire permit application on your behalf, including engineered drawings if required, and manages communication with your local building department through approval and final inspection. If a contractor suggests skipping the permit process or asks you to pull the permits yourself, treat that as a serious red flag.
What Materials Do You Use?
The materials used for your outdoor lanai determine how long the structure will last and how well it holds up to Florida’s climate. Aluminum is the standard framing material for lanai construction in Florida because it resists corrosion, does not rot or warp, is not vulnerable to termites, and meets Florida’s strict wind-load building codes.
Ask specifically about the framing system, the screen material, the hardware and fasteners, and the finish options. A contractor using quality materials should be able to name the products and explain why they chose them. The screen material is especially important: premium screens last longer and provide better UV filtration, insect protection, and visibility than entry-level products.
What Does the Construction Contract Include?
A detailed written contract should cover the full scope of work, material specifications, a construction timeline, payment terms, projected costs, and warranty information. If a contractor provides a vague estimate with a single line item and a total cost, that is not a contract. A properly documented project protects both you and the contractor.
What Is the Estimated Timeline?
The total timeline for lanai construction typically runs between three and six weeks, accounting for permit review, fabrication, site preparation, installation, and final inspection. The construction phase itself generally takes four to six days, though custom designs may require additional time. Weather is a real factor in Florida and may cause delays, so ask how the contractor communicates schedule changes.
Do You Offer a Warranty?
A reputable contractor stands behind their work. Ask what the warranty covers, how long it lasts, and what the process looks like if something needs to be addressed after the project is complete. A contractor who avoids the warranty conversation or offers only vague assurances is a risk.
Red Flags to Watch For
The questions above help you evaluate a contractor’s qualifications. The table below summarizes what strong and weak answers look like in practice.
| Question | What a Qualified Contractor Provides | Red Flags |
| Licensing and insurance | Current license number you can verify; proof of insurance with valid dates | Cannot produce documentation; asks you to “just trust them” |
| Experience with Florida lanais | Specific project count; photos of completed work; references available | Vague claims; no Florida-specific experience; no portfolio |
| Permitting | Handles all permits, engineering, and inspections on your behalf | Suggests skipping permits or asks you to pull them yourself |
| Materials | Names specific products (framing, screen, fasteners); explains material choices | Generic answers; unwilling to discuss material brands or specifications |
| Contract | Itemized written document with scope, materials, timeline, costs, warranty | A single-page estimate with one line item and a total |
| Timeline | Provides a realistic range with milestones; communicates proactively about delays | Promises an unrealistically fast turnaround; no plan for weather delays |
| Warranty | Clear terms, defined duration, documented process | Avoids the topic or offers only verbal assurances |
Commercial Residential Aluminum Offers the Best Lanai Enclosures in Florida
When you evaluate CRA against the questions above, every answer meets the standard Florida homeowners should expect from a lanai contractor.
CRA has been serving Gulf Coast homeowners since Perry Hickok joined founder Tom Teffenhart as partner in 1992. President Tom Teffenhart holds a special Aluminum Structure license, and CRA is a Florida State Licensed Contractor (Lic. SCC056736, CGC058897) that is fully licensed and insured for both residential and commercial work. The company is an Accredited Member of the Better Business Bureau with an A+ rating, a member of the Florida Aluminum Association, and a member of the National Association of Homebuilders.
CRA’s entry and lanai enclosures are custom-designed and engineered for each home, with careful consideration for the property’s surroundings, the local wind speed zone, and the homeowner’s design preferences. Every enclosure is built using CRA’s proprietary ChannelLock Self-Mating Beam (SMB), backed by nine U.S. patents and carrying Florida Product Approval Designation FL#19700. This beam is 40 percent stronger than the typical industry beam and is available exclusively to CRA customers. All CRA products carry either a Florida Builders Approval Certification or a NOA (Miami/Dade) approval.
CRA pre-fabricates each lanai enclosure in a controlled environment for precision fit, then installs on site with licensed and experienced crews. The company handles every step of the process, from design and HOA review through permitting, engineering, fabrication, installation, and final building inspection. CRA uses CRA Premium Screen, engineered to our specifications, on all new construction and rescreening projects.
For homeowners who want to learn more about the lanai installation process, CRA has published a detailed guide on what to expect during a lanai installation in Florida, covering each stage from consultation through final sign-off. For those new to the concept, CRA’s guide to what a lanai is and why Florida homeowners build them is a helpful starting point.

Frequently Asked Questions
1. How much does lanai construction cost in Florida?
The cost of a lanai varies based on the size of the enclosure, the design complexity, the materials selected, and the permitting requirements for your specific location. Because every CRA lanai enclosure is custom-engineered, CRA provides project-specific quotes after an on-site consultation and measurement. Request a quote from CRA to get a price tailored to your project.
2. Do I need HOA approval before building a lanai in Florida?
If your community has a homeowners association, you will likely need HOA approval before a permit application can be submitted. Many Florida communities require written HOA approval of structural additions, including lanai enclosures. CRA recommends starting the HOA review process early to avoid delays, and your CRA project team can help you prepare the design specifications needed for submittal.
3. What is the difference between a lanai and a pool cage?
A lanai enclosure is typically a smaller screened structure designed to convert a covered patio, porch, or outdoor room into a screened-in living area. A pool cage is a larger screened structure built over the entire pool and surrounding deck. Many Florida homes feature both, often connected, to create a unified outdoor living space. CRA installs both lanai enclosures and pool enclosures.
4. Can I screen in an existing patio or porch to create a lanai?
Yes. Screening in an existing covered patio or porch is one of the most common lanai construction projects in Florida. The contractor will assess the existing structure, evaluate the ground conditions, and determine whether additional framing, a foundation, or other modifications are needed to support the screen enclosure. A building permit is still required for this type of work.
5. What happens if a lanai is built without a permit in Florida?
Unpermitted structures can result in fines from your local building department, orders to demolish the structure, and serious complications when you sell your home. Buyers’ lenders and inspectors will flag unpermitted work, which can delay or derail a sale entirely. A licensed contractor like CRA handles all permitting and ensures the completed structure passes final inspection.
6. How do I verify that a Florida contractor is properly licensed?
You can verify a Florida contractor’s license by searching the Florida Department of Business and Professional Regulation (DBPR) website. Enter the contractor’s name or license number to confirm that their license is current and in good standing. CRA holds Florida State Contractor Licenses SCC056736 and CGC058897, both of which can be verified through the DBPR.
