Jared was at our home yesterday to give us a quote on replacing some windows. He answered all our questions regarding construction and timing in the addition to giving us the estimate. We found him to be knowledgeable and we’re impressed with his presentation. We decided to go with this company.

I’ve had a great experience working with Nagy Brothers. Their professionalism stands out right away, and they actually follow through on what they say they’ll do, which isn’t always the case these days. Communication is clear, the work is solid, and you can tell they care about doing things properly. I’ve already recommended them to several people and will keep doing so.

Nagy Brothers installed all new windows for all the units at Creekside Villas one year ago. There are 3 condo buildings on this property. They were very professional, got the work done in a very timely and organized manner, consistent with what they had promised. The workmen that installed my windows were very informative and worked quickly to do the installation. They did a follow-up to make sure I was happy with the work done. I am very satisfied with the results and would highly recommend them to anyone needing windows. This seems to be the same feeling my neighbours had and any of the residents I have spoken to about their experience with Nagy brothers. Excellent job!

As both the resident manager and an owner of our complex I can say without doubt that the team at Nagy was absolutely amazing to work with. From a managerial standpoint they were quick and efficient handling everything themselves from scheduling units to corresponding with residents and access to the units. From an owners stand point the windows they installed have been a fantastic upgrade. My heating/ cooling bill has seen a decrease and the noise reduction is very noticeable.
They were also very approachable and answered any and all questions ( I had many) with clear and responsive communication. I highly recommend Nagy.

As a contractor I've been buying windows and entry doors exclusively from Nagy Bros for the last few years. Their pricing is fair, product quality is great and their service is great too. I would highly recommend Nagy Bros to other contractors and to homeowners!

We had such a great experience with Nagy Bros on our full house project (22 windows and 2 door). Everyone we worked with was professional, friendly, and cared about doing a quality job. Our sales rep, Jared, was knowledgeable, approachable, responsive, and never pushy — which I really appreciated. The quote was competitive, and the installation crew (Scott, Dave, and Diana) were amazing. They worked efficiently, kept everything clean, and their experience really showed in the finished result. They were so kind and patient with my kids asking lots of questions throughout their workday!
Rob was great with following up to make sure all the final tasks were complete.
I’d highly recommend Nagy Bros to anyone considering a window project — they made the whole process smooth and enjoyable.

I had all my windows installed by Nagy Bros, and I couldn’t be happier with the experience. The entire team — from the owners and office staff to the installers — was friendly, professional, and courteous. The work was completed on time, and they left my home spotless when finished. They even followed up after the installation to make sure everything was perfect. Highly recommend! A sample of one window replacement. Before and after.
