My Dad turned me on to Kelly Windows after I told him the price I was quoted from Home Depot for a "special order window." Mind you there was nothing special about the size of the windows that I was looking for. They simply were out of stock. Hence, special order. Anyway, my Dad used Kelly at least 20 years ago and his windows were still going strong up until my parents moving four years ago.

The price quote for 5 windows was just about what Home Depot wanted for 1 Andersen. The quality is second to none. The customer service is great. I simply can not say enough good things about this company. It was worth my drive from up near West Point to Farmingdale. Thanks again Kelly Windows.

I was extremely impressed with Kelly Windows and would absolutely recommend them to anyone that needs their windows replaced. On the administrative side, their professionalism and responsiveness was top notch. On the installation side, their level of quality, flexibility, and overall attitude of putting the customer first was extremely appreciated.

We had just renovated our condo and wanted to make sure we went with a company that was respectful and careful in our new place - and I'm so happy we went with Kelly Windows. From the beginning consultation to the follow up at the end, it was first class service through and through. If you're researching window companies no need to waste any more time.you will not regret working with Kelly Windows!

I live in a co op in forest hills and we are having our windows done over. Old rickety drafty crusty windows. The board hired Kelly. The guys and lady just finished. Great job! Everyone is very professional and obviously takes pride in the job. They are friendly safe and experts in windows. The windows themselves are great. Soundproofing is fantastic. No more draft. Less dust coming in. Very happy. Thanx guys. From 1B
