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. 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.

 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.

FAQs

Can keeping old windows lower my home’s value?

Yes. Outdated or damaged windows signal poor maintenance to buyers. New, energy-efficient windows boost curb appeal, resale value, and inspection confidence.

I heard all replacement windows are the same—is that true?

Not even close. Differences in glass type, frame material, energy ratings, and installation quality can mean the difference between comfort and costly regret.

What’s a hidden benefit of upgrading interior doors?

Sound privacy. Solid-core interior doors help reduce noise transfer between rooms—ideal for home offices, nurseries, and bedrooms.

Do I have to compromise on style when choosing impact-rated doors?

Not at all. Our impact-rated doors come in a range of sleek and traditional designs with custom finishes, sidelites, and decorative glass options.

How long do modern window seals really last?

Seals in high-quality windows—especially when installed correctly—can last 20+ years. Our installs come with warranties that back this long-term performance.
