Reviews From Our Darien Connecticut Window Customers

“I was especially pleased with our installer, Taras Lemekha. He was AWESOME. He was punctual, worked very hard on a hot day, and did a fantastic job. Give that man a raise! I have already recommended you to friends. THANK YOU!”

Gene & Jackie B. – Darien Connecticut 

“Had all my windows and slider replaced by Marcin. He arrived each day at 8 a.m. and worked nonstop until 5:30 p.m.. it took him 2 days to do the work, he worked in the rain, wind, and cold. He has an amazing work ethic. Our salesman Dan was terrific, Service after the sale was great. Had an issue with the slider screen door lock. It was replaced with no issue. A follow up phone call from AWS to see if I was happy with the repair.”

Victoria G. – Stamford Connecticut 

“Dennis and his crew were very fast! The Windows look great and are easy to use. They crew cleaned up after themselves. We will refer AWS to our friends and customer service was excellent.”

Rosita H. – Norwalk Connecticut 

“Top notch Professionals from start to finish! The sales rep was very friendly and kind (he listened to my elderly mother with respect and patience both visits), and the two installers went above and beyond in removing our old cast iron tub and installing our new walk in shower. They did an amazing job and I highly recommend AWS if you’re looking for a great company to install a new shower. Thank you for making my mom’s life so much easier. I greatly appreciate it!”

Jeff K. – Norwalk Connecticut 

“The windows we bought from AWS are terrific and the installer, Mario, was punctual, neat, precise and very accommodating to our work from home lifestyle. Highest recommendation for great product and service.”

What Makes Our Vinyl Replacement Windows the Best Choice For Your Darien, CT Home?

Energy Efficiency

Darien, CT, is known for experiencing unforgiving winters and scorching summers. If you choose to replace your windows, you will save money on with efficient vinyl windows from AWS! Throughout our 40 years of business and research, we have learned what areas of your window lose the most heat. The frame, glass, and edges are where you will often find air escaping, or drafts blowing. We’ve added weather stripping to every edge to prevent this energy loss. Additionally, we have installed multiple panes with Low E coating and Argon gas so that the glass itself can act as an insulator. The finishing touch is that the frame is lined with foam to further increase energy efficiency. This will also make sure that your windows are sealed tightly!

Advanced Window Systems offers the most energy-efficient windows for your home in Darien, CT. We build our windows with efficient glass, multiple seals, and strong vinyl to ensure that they are the highest-quality. The vinyl windows we sell at AWS have the tightest seal with only a .02 air leakage rating.

High-Performance Parts

At Advanced Window Systems, our vinyl windows are made of high-performance components. We guarantee that you can rest easy with your new AWS windows in your Darien residence. AWS windows are strong; they will not crack or sag due to the usual wear and tear like other windows. Our vinyl windows are the most durable and will stay in great condition throughout the years.

Unparalleled Warranty

We at Advanced Window Systems, LLC want to make sure you are protected from undue damage on your windows. Every vinyl window we install for Darien, CT residents comes with a extensive, transferable, lifetime warranty. We make our windows with only the best quality performance materials and parts on the market.
