I am one of those ladies who is always cold. I could not go another winter with our drafty home windows! We called Sliding Door and Window Replacement Largo to get a quote and were treated professionally and fairly from the beginning.Replacement windows in Clearwater should be handled by the pros at Karoly Sliding Door and Window Replacement Largo. It was a pleasure to work with a local, established business and I know we got the best windows. We are very happy with the work and will trust them when we are ready for our door installation and patio doors!!

The staff is very unprofessional, got my name and someone else mixed. The owner does not return our phone calls. Needless to say we are not very happy!

I was extremely pleased with the hurricane window installation work done by Karoly from start to finish. The owner came to my home to take measurements and answer all of my questions. I also had occasion to visit the companys office, which was very modern and professional. The staff kept me fully-informed throughout the process and was always available to answer my questions. On installation day, the installers were prompt, did excellent, very professional work, and cleaned up after themselves. I highly-recommend Karoly Windows and Doors; you will not be disappointed!

The owner came out to talk to me about my sliding door, French doors and Windows. He discussed my options; measured the windows and doors, told me my door cost & window cost. He sent me a detailed estimate with drawings and dimensions for each window, the sliding door, and French doors. The office staff was amazing. They walk me through the entire project. The price was competitive with other vendors, but not the lowest. I decided to go with Karoly because of his reputation, knowledge of windows & Doors, and the products he use (best windows and best doors). The windows arrived when he estimated. The installation was completed in the time agreed upon. The workers who came to my house were professional, courteous and did their best to keep the mess at a minimum. They cleaned up after themselves and I was extremely satisfied with the installation. When the building inspector came through, he was impressed both by the windows & doors and the quality of installation. I would highly recommend Karoly to anyone looking to install or replace their windows & doors. They know what they are doing and take pride in their work. I am extremely happy with my windows & doors and those who installed them!

Karoly Windows & Doors performed a good job when installing new hurricane windows and doors for my house. They scheduled each appointment and arrived within given timelines. I would definitely recommend this company to others.

Karoly is the very best and the staff is A number 1. Karoly will listen to your needs and make recommendations. You can trust what he says and will do that and more. The installers work for the company and have a system next to none, know what they are doing and do it without incident. Look around you won’t find a better service company in any field.

Don & I are so impressed with the exceptional quality of our impact resistant windows and the outstanding workmanship of the installers. The initial visit to give us the overview of what to expect was spot on! We heartily recommend this company to everyone we know and invite them into our home to see for themselves.

I had three large sliding glass doors replaced through Karoly with PGT doors, two, two piece units and one, three piece unit. I am very happy with the quality of the PGT product. I immediately noticed a reduction in noise intrusion and a reduction in how much my A/C was running versus the single pane doors. Karolys team did the install during the pandemic and we struggled getting St. Pete to inspect. I appreciated that they kept following up and in contact throughout the whole process. Ive been trying to get some other projects done, and in a lot of cases these companies dont even call back with an estimate. Thanks, Im happy with my product and the service.

All my sliding door and window worries sloughed off me right when I walked in the door.
