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!

 Trustindex verifies that the original source of the review is Google. 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

 Trustindex verifies that the original source of the review is Google. 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.

Why Buy from Karoly FAQs

What Is the Highest Quality Window Brand?

There are a lot of window manufacturers out there, and all of them claim to be the best. For a few of them, there’s truth to that claim in at least one window performance category.

The two brands that Karoly most frequently works with are Simonton and PGT because these window manufacturers are extremely experienced in the Florida market and make high-quality products that justify their cost.

You can’t really go wrong with either of these premium window brands, as they make top-tier products that will last you a lifetime.

What’s a Good Price to Pay for Windows in Clearwater?

The cost of a window will vary widely depending on what you need in that window. Added features that enhance a window’s impact resistance, energy efficiency, or longevity often mean that the window will cost more.

It’s not unusual for a high-quality window to cost hundreds of dollars or more. Some top quality window brands may even cost thousands of dollars per window. When getting a quote for window installation, be sure to verify the kind of windows the installer is offering in the price quote.

Should I Buy Aluminum or Vinyl Windows?

Aluminum windows can be a great fit for homeowners who want enhanced durability and useful life. However, aluminum windows often cost more than their vinyl counterparts do for similarly-featured products.

Additionally, vinyl windows have inherently better energy efficiency than aluminum, as vinyl (PVC) has a much lower thermal conductivity than aluminum, meaning it lets less heat into your home than the aluminum window will.

How Long Do Your Windows Last?

The useful life of a window can vary depending on the materials it’s made out of, the quality of the installation job, and how well the window is cared for.

Karoly Windows covers every window we install with a Platinum Standard Lifetime Guarantee. This includes a 25-year installation warranty and a 50-year material warranty. We’re confident that the windows we put in for you will last that long with ease.

How Long Does Window Installation Take?

The lead time on a custom window installation project can vary depending on a few factors such as the windows you choose to install, the weather, and the availability of labor to complete the installation. Karoly only uses in-house installers to ensure that every job is done to our high standards of quality.

When you request a quote for custom window installation, our installation tech will be able to give you a time estimate for the project to be completed by.

Why Use Custom Windows over “Standard” Ones?

Why not go to a hardware store to buy your own windows? Especially if you have a standard window opening? Because there’s more to window installation than getting a new window that’s roughly the right size for your opening.

New windows need to be shimmed, insulated, caulked, taped off, leveled, and carefully secured to ensure that they won’t fall out from a stiff breeze or let in moisture from the outside.

Also, in some homes, a structure may ‘settle’ over time, causing window openings to warp slightly with the building frame. Installing windows without accounting for this warping may lead to gaps, cracked windows, and worse.

Why Buy New Windows?

The reasons to buy new windows rather than simply replacing the glass in them are numerous. First, glass repair doesn’t always address the issue that caused a window to break in the first place. For example, if the frame is warped and that put pressure on the window glass to crack it, simply switching out for identically-sized glass may leave you having to replace it again before long.

Second, impact resistance is a system. Switching out non-impact glass for tempered glass doesn’t automatically make the whole window assembly impact-resistant. The frame, glazing, and other materials also need to be designed around impact resistance to ensure that a window can take storm impacts without failing.

Third, window replacement can help you maximize your home’s energy efficiency. Windows that are built to prevent thermal transfer and air leaks help keep your home cooler in the summer so your air conditioning doesn’t have to work so hard to maintain a comfortable temperature.

Finally, some homeowners in Clearwater choose to replace their windows simply to enhance the curb appeal of their home. Replacing windows entirely, frame and all, gives you more control over the appearance of your windows so they more closely match your style preferences.
