I love my new windows. Everyone that help me get started with my project was so friendly and knowledgeable at the Karoly Windows. And the Consultant ( Brandon ) that came out to my house was very nice as well. Thank you Karoly! I look forward to replacing my other windows. - Karoly Windows & DoorsCustomer

The tech who came to measure and explain, was very professional. He kept in touch with me. Even when I had questions or misunderstood something he patiently clarified. Even seeking a different solution if I so desired. The installers were pros. Quick, efficient, tidy. Willing to explain things to me as they worked. They made sure I was proficient at operating my windows. Yes I will call them for my next project and recommend to my friends. I always felt that I was in control of my project. And that my vision was being met as closely as possible. My home is so beautiful to my husband and I. Thanks Karoly Windows & Doors.

We had Karoly Windows & Doors perform a large home project near the ocean. Numerous oversized windows of glass on the second story needed to be replaced, employees were always on time, professional and courteous. I must also compliment the teamwork from Laszlo and Steve. and an enormous ""SHOUT OUT"" to manager Michaela for working so diligently to give us the BEST customer service! She was AMAZING! I highly recommend Karoly!

We love our new windows! Brandon was great to work with throughout the process. Very knowledgeable, responsive and nice. He helped us make decisions without being pushy. This company does not use salesmen which helped us make the decision to go with them. No high pressure sales tactics at all! Brandon is the VP and treated us so kindly and knew so much about the windows. Great price and a great product! The installers were professional, efficient and polite. We are very happy with the service and the product.

I had four Impact windows and a sliding glass door installed in my condo, and Botond and his team of installers did beautiful work and treated our home and the walls surrounding the window frames with the utmost care. The windows themselves are a huge upgrade from the single-panes that came with the condo (built in the '90s), with much better temperature control and a complete elimination of outside noise. The price was very reasonable and they completed the job faster than quoted. 10/10 would work with Karoly Windows & Doors again.

Excellent service from quote to finished product We got three quotes. Brandon's was very reasonable. We love the new windows in our house. The house is quieter and the windows regulate temperature and it is so nice to open and close them, the screens pop out for easy cleaning. I can't recommend having new windows enough! But, it would not have happened without Brandon and our install team Botond and Attila. Crew was very professional, neat and clean. I can't speak highly enough of the service and value. A rare thing these days.

Vili, Botond, Attila were my installers. They installed my hurricane doors and windows. First let me start wit why I chose Karoli. Its an owner operated company. No salesman just the owner that came out and measured. His prices were competitive to one other company and much better than two others. He was no nonsense and the only one that told me the truth about time frame. he was two months further out than his competitor and considering he was using the same windows made me feel like i was dealing with an honest company.

My installers were fabulous. They showed up on time every day and explained what their process was from the beginning. Meticulous, knowledgable, and clean workmanship. They covered my furniture, vacuumed after each window, cleaned the window, checked out the operation to make sure it was correct. Great personailties, pleasant, polite and talented. They did 15 windows, a double entry door, two other exterior doors and a slider in 3 and one half days. Couldn't be happier with how everything worked out. I would recommend Karoly to anyone that asked.

They are a plus plus in my book beyond professionalism exemplary tradesmanship thoroughness and respectfulness to the homeowner and to each other. I would use no other company and I am a big believer when you do installations that they should be employees of the vendor and not subcontractors. I would trust my windows and doors to no one else.

They were very communicative and let us know every step of the way. I live in Michigan and they were replacing a slider at my condo in Florida. I came in town the week of the install and when the installers arrived, they reported that the track arrrived damaged.they went and (thankfully) had a replacement at the office so the install was delayed a few hours but the installers worked until 7:30 pm to make sure the job got done correctly without any issues. Much appreciated!

This company knocked my socks off. Thrilled from the beginning with meeting Karoly. I got a great deal on my impact windows and sliding glass door. Not as long of a waiting period as I anticipated. The installation went off without a hitch. Couldn't be happier. Thanks Michaela and Nicole for helping to make this project go so smoothly. Well worth the money.

Karoly and his employees have been amazing, today they installed our beautiful front doors, and we couldn't be happier with the service, professionalism, and attention to every detail during installation. They caulked every trim piece, and hole. We have our windows and back doors also being installed by karoly and his team, were waiting on the manufacturers, and I'm sure it will be just as great of an installation. My wife and i highly recommend karoly and his team, you won't be disappointed with his services or product.

We used Karoly because of the great reviews. The were professional and on time from the initial measurements, to ordering the windows, keeping us informed on installation date, the pandemic delay from manufacturer keeping us informed, installation went smooth, and they scheduled inspection for the next day. Inspection was great and signed off right away since it was a quality install. I've flipped homes before and very impressed with Karoly. We live in Los Angeles and we were able to plan flights back because they were on time with the install.

We live out of state but wanted high wind windows for our new vacation home. I first emailed measurements and they gave me a quote. Then Karoly himself came out for the final measurements and we ordered the windows. We planned ahead flights back to Florida for the job and it went great. In one day all 7 windows were done. The next day Karoly scheduled the City Inspection and each window was inspected and it passed. Very professional along the way keeping us informed and very happy with our new windows.

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 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.

So highly impressed with the level of care, respect, and professionalism received from everyone I have dealt with in this business! The quality of product, warranty and workmanship is as good as it gets, as far as I am concerned! I got estimates from 4 companies to replace my old sliding patio doors with new impact rated doors. Karoly was not cheapest---nor most expensive. I read the reviews, and basically went on my gut instinct----as I had major reservations in even doing this at all:having been conned by another business at another residence. Karoly himself came to measure:he was very patient and answered every concern I had.

The office staff kept me up to date and was available for any questions--as well as providing easy to understand step by step instructions of the process--the contract---what to expect, etc. The delivery arrived promptly at 7-with installers William and Josef right behind. I am delighted with the outcome. The house and work areas were left neat and clean--and the gentlemen were very respectful and knowledgeable. I feel very fortunate to have contracted with Karoly for this project, and will definitely ask them to replace my windows as well in the future.

Nice staff/crew. The 3 window installations were great. The french door install was good, but as we knew beforehand, it is up to us to complete the project. For part of the "wood" we were given small rubber plugs to fill in small holes to cover screws. They look good, like they are part of the wood. For larger holes to cover screws, we were given plastic plugs that, when inserted, are not flush with the rest of the surface.

So if we use these plugs, there will be bumps every so often. Does not look like classy wood as a result. Gonna have to hire somebody to sand these several screw holes level, then plug w/ wood glue, then paint. More trouble than we anticipated. The end product will look terrific. We just didn't expect the extra work. So our project is still unfinished at this point. FYI: City inspector was very impressed when it comes to meeting code, going the extra mile, etc.

I HIGHLY recommend Karoly Windows and Doors! As a matter of fact, they will probably be busy doing most of our neighbors homes now that they're done with us, sorry guys! After getting an estimate we had them out last week to replace all the windows in our home with more efficient glass and casement style windows as well as replacing a sliding glass door with french doors. They arrived Monday morning and did not stop working until almost 8 pm that night!

They finished the job the next afternoon, two days a head of schedule and no quality was compromised. Our windows look and work beautifully, they cleaned up entirely after themselves and were friendly and cheerful the entire time they were in our home. The city inspector even commented afterwards that he was impressed with their work, as they used 3 times the required amount of screws. I'll take that kind of work any day!
