What to Look for to Find the Best Window Replacement Company

On the hunt for new windows to replace your old ones so your home is more secure against the ravages of hurricanes? Or are you looking to enhance energy efficiency in your home? Whatever your top priority for your new windows is, fill it the right way by finding a window replacement company that:

Has a Long Track Record of Success

The best window replacement companies have a history of success behind them. When looking for new windows, check to see how long the installer has been in Florida and how highly they’re rated.

Has a Consultative Approach to Window Installation

Is the window installer willing to sit down with you to explain your window options and what would fit best with your goals? Look for a window replacement company that takes a consultative approach.

Works with Several Manufacturers

The best window replacement company will be “manufacturer-agnostic.” They may work with top manufacturers, but they should work with several so they can get you the best windows for your needs.

Knows Your Local FBC Guidelines

Different parts of Florida have different requirements for their windows. Pick an installer who knows the special restrictions for your area so you never have to worry about passing inspection.

Uses In-House Installation Experts

Far too many ‘fly by night’ window installers farm out installation work to third parties who don’t know what they’re doing. Find a company that uses only in-house installation experts for your windows.

Is a Certified Special Contractor

Does the window contractor have a license with the Florida Department of Business & Professional Regulation proving that they are a certified specialty contractor authorized to do the work?

One of our installation experts will go to your home and assess your window needs, consult you about what windows best fit them, and provide you with one of the most accurate quotes for service in all of Florida.

Simonton or PGT Windows?

In Florida, there are two window manufacturers who offer the best value for cost on windows: Simonton and PGT. Karoly Windows works with both of these companies to source high-quality impact windows and doors for our customers.

Simonton is a great partner with affordable, high-quality window products that are built specifically for the Florida market. Also, they have one of, if not the, best warranties in the window manufacturing industry. They use pure, unadulterated polyvinylchloride (PVC) for their frames, ensuring long-term durability and chemical resistance. 

PGT is another top-rated brand. One of their biggest differentiating factors is that they do extensive testing of their products. It’s hard to find product lines that are more thoroughly tested and certified than PGT’s WinGuard windows. They have the most well-vetted products on the market, making them extremely reliable and trusted.

Secure Financing to Get the Best Replacement Windows!

Installing new windows can be a costly endeavor, which can force homeowners to put off getting their windows until after it’s too late or miss out on potential energy savings for months or even years. This is where window financing can help.

One of the things that every good window replacement company offers is a multitude of financing options to help make it easier for homeowners to get their new windows installed sooner so they can protect their homes and start saving on their electricity bills.

Karoly Windows & Doors works with financial institutions like GreenSky and Synchrony Financial to provide flexible financing options for window installation. Choose from a variety of financing options, including some that have ‘no payments required’ periods where you can avoid paying any interest if you pay off the loan before the ‘no payment required’ period ends.

I reached out to Karoly for new sliding windows in my florida room and two exterior doors. Karoly came out and spent quite a while getting all the measurements right. That makes you feel good. When the installers came out, two days and done. Windows look great and the doors are solid and close tight. Everything is now impact and hurricane rated. I got my insurance discount. Thanks Karoly!

Villi and Christian did a fantastic job replacing all the windows in my home! Their attention to detail, professionalism, and care throughout the project truly stood out. I'm extremely pleased with the results and want their supervisor to know what a wonderful team they are. Thank you both for your excellent work!

We had a leak under a sliding door, which was installed by the previous owner of our condo. I called Karoly and they came in less than 3 days and the very friendly, professional representatives fixed the issue at no charge.

I am very hard to please as I pretty much expect close to perfection. From a serious point I just want a TEAM that cares and gives it their best. Mistakes happen. However today I had Hurricane windows placed by Karoly. Actually from the very beginning it was like dealing with a family. In all my dealing with different companies A/C etc they far outshined any company I have ever dealt with. My techs were Vili, Zoli and Christian. They gave 150%, were very clean, cared about our house and did exquisite workmanship. 1,000% incredible and guess what they are not my relatives. LOL

I will never be able to brag enough about how superior this company is. My husband and I interviewed at least seven window companies, all full of similar products of PGT or other hurricane safe Windows. We became window experts on our own with the knowledge we absorbed comparing apples to apples. Karoly was the final company we met with and Austin presentation was simple and he showed us a sample and did all the measurements. He explained the Simonton brand very well and the warranty they offer cannot be beat. We visited their showroom and met with Jesse to really look at products. Our decision was quick and easy and the price was better than their competitors. We completed all the paperwork with Richy and Angela and the rest of the wonderful staff. Installation day came and we met the fantastic installers that were so kind and clean. In 3 days our job was done. The day after that inspector came and passed us and one week later Karoly came back to complete final installation of some parts and now it’s all finished. These windows have changed our home completely. Not only did we work with the best contractor and save money we also gained a more beautiful home and it’s so quiet! No barking dogs or loud traffic or thunder anymore just peaceful tranquility!!! Thank you everyone at Karoly for making us so happy!!! I promise to call you again for all my other houses!! This was the best thing we’ve ever done without a doubt . Sincerely, Cheryl & Doug Sigmon

Thrilled with our new windows and doors. Dealing with Karoly, from no pressure sales, installation, and close out was great. They kept us informed and did everything they said they would. Highly recommend Karoly Windows and Doors!

After researching a few companies, I decided to go with Karoly. They replaced 19 windows and 3 sliders with Sinomton Stormbreaker Plus 300VL and Simonton Maxview. I enjoyed reading the information they had on their website and pleased to see this is a family owned business with emphasis on quality work and customer satisfaction. Employees were pleasant and professional and answered my questions. It has only been almost 2 years since installation and from my experience thus far, I would highly recommend Karoly.

I couldn't be happier with my experience with Karoly Windows & Doors! They replaced all of my windows along with two doors, and the entire experience exceeded my expectations. From start to finish, everyone was professional, friendly, and truly cared about doing the job right. The installation crews were outstanding. They were hardworking, respectful of my home, paid attention to every detail, and the quality of their workmanship was exceptional. I'm extremely pleased with the quality of the window replacement, the beautiful new doors, and the finished results. I was so impressed with the company that I've already recommended Karoly Windows & Doors to several of my neighbors. It's refreshing to work with a company that delivers exactly what they promise. If you're considering window replacement, I highly recommend Karoly Windows & Doors. They are a true first-class company, and I couldn't be more satisfied with the entire experience.

Best Replacement Window Company FAQs

What Is the Best Window Replacement Company?

The best window replacement company is the one that will go the extra mile to provide you with the best service, support, and quality. It’s the company that backs all of their work with a parts & labor warranty that lasts for decades, not months or years.

It’s the company that does everything it can to ensure consistent quality on every window installation by using in-house labor. It’s the company that isn’t beholden to a single window manufacturer so they can shop around to find the best windows at the best prices to meet your needs and your budget.

It’s the company with a long and proven history of doing top-quality work in the area you need window replacement services in. It’s the company with the knowledge and experience to handle every part of your window replacement service the right way, every time.

For many homeowners throughout the greater Tampa Bay area, it’s Karoly Windows & Doors.

Yes. The Florida Building Code “requires windows to be impact-resistant or protected if located within one mile of the coast where the wind speed is 110 mph or greater.” Even if you’re more than a mile away from the coast, installing impact windows is a good idea to protect your home from the effects of major storms when they make landfall.

The FBC specifies impact windows because many of the areas close to Florida’s coastline are designated as “wind borne debris” (WBD) regions. These areas face an increased risk of being struck by flying debris compared to more inland regions.

If a non-impact window gets struck by a flying piece of road debris or is simply subjected to heavy wind pressure, then it’s more likely to break. With only a single pane of glass between your home and the outside, that could have catastrophic consequences for your home as that debris, wind, rain, insects, wastewater, and more comes into the structure.

The answer to that question depends on what you’re looking for in a new set of windows for your home. If you want a sweeping vista view of the beach and don’t need the windows to open, then a picture window might be a great option. 

If you want to save money on your energy bills for decades to come, then a low-e glass window might be the perfect fit for your needs.

When choosing windows for your home, it helps to:

  • Create a list of priorities, such as saving money on your energy bill, hurricane-proofing your home, enhancing curb appeal, etc. and rank them from highest to lowest.
  • Determine your budget by seeing how much you can afford to spend on windows or how much window financing you can qualify for and pay off within a set schedule.
  • Check into any available rebate programs from government agencies or even private organizations. For example, the My Safe Florida Home program offers rebates for making wind mitigation improvements to your home and adding ENERGY STAR windows can qualify you for energy incentive tax credits.

Because so many different homeowners and homes have so many different needs, we start every window replacement service with a free in-person consultation. During the consultation, we send an expert to your home to measure your windows, review the requirements for your area, and find out what your biggest priorities are.

This is how we ensure we’re installing the best windows for your home.

Yes! The windows in your home can play a large part in determining your home’s energy costs. Windows are one of the easiest ways for the cooler air in your home to leak out or for the sun’s heat to penetrate into your home.

Both of these issues mean that your AC has to work harder to keep your home cool. This, in turn, increases your energy costs to run your AC. Windows with low-e coatings, multiple layers of insulating glass, argon gas fills, and other energy efficiency features can help you reduce your electric bills.

The specific amount of energy saved will depend on a lot of factors. For example, if you’re going from single-pane aluminum windows to double-pane insulated windows with vinyl frames, that’s going to be a much larger increase in energy efficiency than going from one vinyl window to another.

This is because aluminum windows are vastly less energy efficient than vinyl windows. Aluminum has a thermal transfer coefficient that’s vastly higher than vinyl’s—237 watts per minute Kelvin versus 0.19 W/m K, according to Engineering Toolbox. In other words, aluminum transfers heat between the outside and your home over a thousand times more than vinyl does.

Additionally, other insulation in the home can put a cap on how much energy efficiency your windows can provide. If you have the best energy efficiency-enhancing windows, but there are large gaps in your walls, then the windows won’t provide the full benefit that they normally would.

Windows are just one (very important) part of a whole home energy efficiency system. 

Yes! Karoly Windows & Doors works with the best window manufacturers in Florida to bring you high-quality windows that meet the American Architectural Manufacturers Association’s strict guidelines.

This is why we partner with manufacturers like Simonton and PGT. They have extremely well-tested impact windows that are certified to meet Gold Label standards for AAMA certification. 

By working with multiple top-quality manufacturers, we can help ensure that you get the best windows at the best price for your home.

Our 100% in-house team of window installation experts also do everything the right way on installation. This is part of the reason why Karoly Windows & Doors is the best window replacement company in Florida!

When a window replacement company outsources its work to third-party contractors, you never know if the people working on your windows are qualified to do so. This can bring a variety of subcontractor-related risks. 

The most common issues with subcontracted work on window installations include (but aren’t limited to):

  • Inconsistent Work. With subcontractors, you’re playing a game of Russian Roulette when it comes to their work ethic and competency. One subcontractor might be brilliant and well-trained, the next might barely know how to hold a hammer. Also, your window installation might get put far down the list of the subcontractor’s priorities.
  • Insurance Liabilities. Unlicensed and uninsured subcontractors pose a massive liability risk for homeowners. If the unlicensed subcontractor who doesn’t have insurance gets hurt on the job, you may be on the hook for their medical costs as the property owner.
  • Project Cost Overruns. With some subcontracted work, you may find surprise additional charges for ‘unforeseen’ expenses that the window sales company didn’t take into account because they don’t really know the installation side of the work and didn’t quote it properly for whatever unique circumstances impact your installation job.
  • Safety Risks. This is an issue that combines with the insurance liability to make subcontracted work even riskier. Undertrained and unlicensed subcontractors are more likely to make mistakes that lead to injury or property damage.
  • Lack of Accountability. If the subcontractor does the installation wrong, who can you talk to in order to get the issue resolved? Who’s responsible for ensuring your satisfaction with the work done? With subcontracted labor, the answer can quickly get murky as the subcontractor and the main contractor pass the buck back and forth. If you can get in touch with the subcontractor at all.

Risks like these are among the top reasons why it’s better to go with a window installation company that uses in-house labor rather than outsourcing it to a third party subcontractor.

So, why do you need top-quality windows from the best window replacement company? Because they can actually save you money in the long run.

A poorly-installed window can fall out because it isn’t sufficiently secured to the frame, there may be air or water leakage from an improperly-sealed opening, or they may just not work quite right because they’re ever so slightly too large for the opening.

This can lead to a variety of expensive problems that cost you money later. 

For example, if your window lets in air and water from the outside during rainstorms, it could cause water damage and even mold growth in your home. A window that simply falls out because it isn’t sufficiently secured might let in wind, rain, and storm debris during a hurricane, requiring extremely expensive water damage remediation and the loss of property in the home. In extreme cases, it could lead to significant structural damage to your home.

Poorly-installed windows may also fail faster than ones that are properly done, forcing you to buy new windows sooner rather than later. This can result in you actually spending more than you would if you’d bought higher-quality windows from a reputable and reliable installer the first time.

So, in the long run, it pays to spend more on a high-quality window installation now than having to regret getting bad windows installed poorly later.
