15 Important Questions to Ask Your Window Installer Before Hiring
You’ve started asking around about window installers, and now you’re second-guessing everything. Who’s actually licensed? What questions do you even ask? If you’re an Orlando homeowner trying to figure out who to trust before someone starts cutting into your walls, you’re in the right place. These 15 questions aren’t just a checklist — they’re the difference between a job done right and a repair bill you didn’t see coming. We’ve worked in this market long enough to know exactly where things go wrong, and we built this guide around those moments. By the time you finish reading, you’ll know more than most homeowners ever think to ask — and you’ll be able to tell immediately whether the installer sitting across from you actually knows what they’re doing.
Licensing and Insurance Protect You From Costly Surprises
Before you let anyone touch your windows, ask two things: Are you licensed in Florida? Do you carry liability insurance and workers’ comp? Most homeowners skip this entirely — and it’s the one that costs them the most when something goes wrong.
In Florida, window installers are required to hold a valid contractor’s license issued by the Florida Department of Business and Professional Regulation (DBPR). That license isn’t just paperwork. It means the contractor passed a trade exam, met financial responsibility requirements, and can legally pull permits in your county. An unlicensed installer cannot pull a permit. And in Orange County, that matters.
Here’s what most guides get wrong about this: they tell you to “verify the license” without explaining what you’re actually looking for. Go to myfloridalicense.com. Search the contractor’s name or license number. You want to see an active status — not expired, not suspended. A lapsed license is still a lapsed license, even if the installer seems professional and experienced.
Liability insurance covers damage to your home if something goes wrong during the job. Ask for a certificate of insurance — not just a verbal confirmation. A legitimate company hands that over without hesitation.
Workers’ compensation is the one people forget. If a worker gets hurt on your property and the contractor doesn’t carry workers’ comp, you could be held liable under Florida law. Florida requires workers’ comp for construction businesses with one or more employees, with some exceptions for sole proprietors. Ask specifically about workers’ comp — don’t assume it’s bundled into “insurance.”
One more thing worth knowing: only a licensed contractor can legally obtain a building permit for window replacement in Orlando. Florida’s building code requires permits for most window replacements, especially when you’re changing the size or type of opening. Permitted work gets inspected. That inspection protects you when you sell — unpermitted window work can delay or kill a sale.
Ask the installer directly: “Will you pull the permit, or will I need to?” If they say permits aren’t needed — or that you should pull it yourself as the homeowner — that’s a flag. A licensed contractor handles the permit. That’s part of the job.
Licensing and insurance questions feel uncomfortable to ask. But any installer who gets defensive has already answered your question. The good ones hand over documentation before you even finish asking. If you’re unsure how to evaluate what you hear, it may help to speak with an experienced Orlando window installation professional who can walk you through exactly what to look for.
Experience and Local Track Record Tell You What Reviews Cannot
A five-star rating looks great on a screen. But it doesn’t tell you whether the installer has ever worked on a 1960s concrete block home in the middle of a Florida summer. It won’t tell you if they understand the expansion gaps that Orlando’s heat and humidity demand. Reviews are a starting point. Not the whole picture.
Ask the installer directly: how long have you been doing this work, and how much of it has been in Central Florida? Those are two different questions. A company might have twenty years of experience in Ohio and two years here. That matters. Window installation in Orlando isn’t the same as installation in a dry or cold climate — stucco exteriors, high-humidity conditions, and Florida Building Code requirements all change how the job gets done.
One thing most guides get wrong: they treat “years in business” as the main measure of experience. A company can be in business for fifteen years and have spent most of that time doing siding or roofing. Ask specifically how many window installations they’ve completed — and how many were in homes similar to yours.
Ask if the installer has completed projects in your specific neighborhood or with your home’s construction type. Concrete block, wood frame, and newer vinyl-sided homes all require different approaches at the rough opening. A good installer won’t hesitate. They’ll probably describe a specific nearby job without you even having to push.
Licensing is the floor, not the ceiling. A valid license only tells you they met the minimum standard to operate. It doesn’t tell you how they handle a job when something unexpected comes up — a rotted sill plate, a frame that’s out of square, a rough opening that doesn’t match the window specs. That’s where real field experience shows.
Local track record also means local accountability. A company with deep roots in the Orlando area has something to lose if a job goes sideways. They have neighbors, referrals, and a reputation built over years of work in the same community. That’s a different kind of motivation than a crew that travels in for a season and moves on.
It’s also worth checking how local window companies handle complaints before you commit — patterns in customer feedback can reveal a lot about how a contractor operates when things don’t go as planned.

Product and Installation Method Questions Reveal the Quality of the Work
Most homeowners focus on price. But the questions that actually protect you are about how the work gets done. Before you sign anything, you need to know what product is going in your wall — and exactly how it’s being put there.
Ask the installer what window line they plan to use for your home. A good installer can tell you the series, the glass package, and why that product fits your specific opening. Can’t answer that clearly? That’s a signal. We’ve had homeowners call us after another company installed the wrong product for a Florida coastal zone — the glass wasn’t impact-rated, and it had to come back out.
What you actually want to know is whether the product is rated for your local wind load requirements. In Orlando, that means checking Florida Building Code compliance for your specific county and wind zone. Ask specifically: Is this product approved under the Florida Product Approval system? Every window installed in Florida should carry a Florida Product Approval number. If the installer looks at you blankly when you ask that, walk away.
The installation method matters just as much as the product itself. Two common approaches exist: full-frame replacement and insert (pocket) replacement. Full-frame means the old frame comes out completely. Insert means the new window slides into the existing frame. Neither is always right — but the installer should tell you which method they’re using and why it fits your home.
Ask how they handle the rough opening. Do they use low-expansion foam? Backer rod? What flashing tape goes around the exterior? These aren’t trick questions — a trained installer answers them in thirty seconds. The foam and flashing details are what keep Florida’s afternoon rain from getting into your wall cavity.
Also ask about the sill pan. A proper sill pan — either pre-formed or site-built with waterproof membrane — catches any water that gets past the window and directs it out. Skipping the sill pan is one of the most common shortcuts we see in this market. It’s not visible once the window is in, so some installers skip it hoping you’ll never know. You’ll know in about two years when the drywall below your window starts to bubble.
One more thing: ask how many people will be on the installation crew. A single person installing a large picture window is a red flag. Proper installation on anything over a certain size requires two people to hold the unit square while it’s fastened. A racked window won’t seal correctly no matter how good the product is.

Frequently Asked Questions
Do I really need to verify a window installer’s license before hiring in Orlando?
Yes — verifying the license is one of the most important steps you can take before hiring anyone. In Florida, window installers must hold an active contractor’s license through the DBPR. An unlicensed installer cannot legally pull permits in Orange County. You can check license status directly at myfloridalicense.com. Look for “active” status — not expired or suspended.
What is a common mistake homeowners make when hiring a window installer?
The most common mistake is assuming “insured” means the installer also carries workers’ compensation. Those are two separate things. Liability insurance covers damage to your home. Workers’ comp covers injuries to workers on your property. Under Florida law, if a worker gets hurt and the contractor has no workers’ comp, you could be held responsible. Always ask for both — and ask for a certificate of insurance, not just a verbal answer.
How does Orlando’s climate affect window installation compared to other states?
Orlando’s heat, humidity, and storm season create conditions that out-of-state installers may not be prepared for. Stucco exteriors, high moisture levels, and Florida Building Code requirements all change how the job gets done. Expansion gaps, flashing details, and impact-rated products matter more here than in dry or cold climates. An installer with experience specifically in Central Florida will understand these differences.
Who is responsible for pulling the building permit for window replacement in Orlando?
Your licensed contractor is responsible for pulling the permit — not you. Florida’s building code requires permits for most window replacements, especially when the size or type of opening changes. Permitted work gets inspected, and that inspection protects you when you sell your home. If an installer tells you permits aren’t needed or asks you to pull it yourself, that is a red flag. A licensed professional handles this as part of the job.
Does a window installer’s years in business tell me how experienced they really are?
Not always. A company can be in business for many years and have spent most of that time doing roofing or siding — not windows. Ask specifically how many window installations they’ve completed and how many were on homes like yours in Central Florida. Local experience with Orlando’s stucco exteriors, humidity, and Florida Building Code requirements matters more than a general track record from another state or trade.
Where can I find a licensed, experienced window installer in Orlando?
Start by verifying license status at myfloridalicense.com, then look for companies with verifiable local reviews, a history of permitted jobs in Orange County, and crews experienced with Central Florida construction types. A company willing to answer all 15 questions on this list — clearly, without hesitation — is a company worth calling.
