  • We do not offer repair work of any kind – no sliding glass door repair, no window repair and no front door repair.
  • If the glass in your window is broken and but you do not want to replace the entire window, you would need to contact a glass replacement company to have it properly replaced. You may want to consult with the manufacture’s warranty on your window to be sure you don’t do anything to void the warranty.
  • Karoly is licensed for the size for size replacement of residential windows and doors. If you want to have a window converted into a door or a door converted into a window, we are not licensed to modify the exterior structure of your home. We also cannot install products into buildings that are zoned as commercial.
  • Since our manufacturer custom builds the windows to fit your exact size window openings, there is a 4 window minimum purchase requirement. Once your windows go into production, we are not able to cancel the order.
  • If your home was built before 1952, chances are the exterior of your home is painted with lead paint. We are not able to install windows or doors in Tampa homes with lead paint. If you have certification of lead paint removal, we can do an estimate on your project.

Karoly Windows and Doors is an excellent company! I recently needed a door replaced on my Lanai and I hired Karoly. The owner came to my home and measured the job himself! The administrative staff at the office were a delight to deal with as well. And, last but NOT least, the installation crew was outstanding. They were friendly, knowledgeable and hard workers. I would highly recommend this company 😊

I am extremely happy with the services. The experience was simple Karoly the owner came out did the measurements. I worked with the office regarding scheduling. The office was responsive. The installer crew took care of my house and covered everything. The clean up was spotless. The building inspector said installation exceeded the requirments. Karoly Windows and Door exceeded my families' expectation. I recommend them for any door/window installation

I am a repeat customer. I used Karoly in 2013 to install (5) 9ft PGT sliding doors & 5 Simonton windows. Because of his proficiency, attention to detail, and astute knowledge pertaining to installations (everything fit perfectly the first time!) I referred to him as the "Einstein" of door and window installers in that review. This time I used Karoly to install an entry door. Everyone who works for him is trained under his watchful eye until he is confident they can do installs to his satisfaction, which is true perfection. I was not surprised to learn that is business has expanded since 2013 from one location to three! Thank you Karoly. The entry door is perfect and you are still the "Einstein" of door and window installers!

Had a great experience with Karoly. He was recommended by a co-worker. I ordered right before all the fun started with Corona virus. The order was delayed by a couple weeks due to the stay at home orders. The office ladies kept me in the loop and were always helpful. The actual installation was highly efficient. I had 19 windows and 3 doors replaced and they were complete with the work in exactly 2 days. The workers were extremely professional, did a great job on the install, and cleaned any mess that they made which was very little. The windows look great ( I got the Simonton Stormbreaker) and couldn't be happier with the service and price. Absolutely highly recommend.

We meet with over 10 companies and went to a home show all before making our decision to go with Karoly Windows and Doors for the purchase of our Simonton Windows and the installation of a front door and garage side door. The owner, Karoly Szekeres, does all visits and selling of services. We found him to be very trustworthy, what happened is what he said would happen. Ordering was great, with office follow-up to the very end and the installers are fantastic and clean up is exceptional. The windows are exactly what we wanted and Karoly represented them professionally and honestly. If you do not want to be pressured and are looking for great windows at an excellent price, go with Karoly Windows and Doors. We had 11 windows and 2 doors installed and all went well...better than expected.

We are very pleased with Karoly Windows and Doors. The house we picked this spring was amazing however, being situated on a golf course and having elderly owners precede us made an upgrade to the window and door process necessary. We reached out to several companies for quotes. Karoly was middle of the road for price but nearing the top on quality product and available reviews. We decided that Karoly was the company for us. Karoly measured our house, gave us a quote and passed us to Cynthia who completed our preorder and scheduling. The windows arrived with no problem and were installed over a 3 day process. (It's a big house). The team was timely and polite, they were also honest though an accident resulted in sprinkler damage the team was fully communicated the mishap and fixed the issue. After the team had left one of the many hurricane systems swept through the area. We noticed one of the windows leaking we called Karoly they came out and fixed the issue as soon as the rain had stopped. We liked this company for the transparency, the efficiency, the cost, the follow up care. We can confidently recommend them to anyone in the area needing quality window services.

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 company's 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!

We are very pleased with sliders and doors. The installers were efficient, friendly. and exceeded out expectations. They said that they would be here between 7 and 8 and they were. It would be a nice “touch” if Karoly would visit our home to check out the job. We are very happy that we chose Karoly Windows. Overall Experience Rating: 5 out of 5
