More From Our Satisfied Customers

Advanced Windows & Siding, Inc. replaced all 8 of our basement windows this past summer and they have stood up beautifully regardless of the weather extremes we often experience in the Chicagoland area.  The installation crew was efficient and fast.  The sales team was top notch and pricing very competitive.  We highly recommend them!
– Deborah B.

We are very pleased with our experience. We were very happy to get the windows installed Yesterday, and your crew was efficient, clean, and polite. We are particularly happy with the kitchen awning window, and the nice, clear view and light it brings into the kitchen. We did refer a friend to you, and I believe he is planning on purchasing in the spring. I will update you when we are ready to begin the next stage of replacements, and thank you again for your kindness and efficiency.
– Kate R.

Thank You.  We are pleased to tell you how happy we are with the whole process of working with you and your company.  From the beginning, your company has been very responsive, informative, and on time.  You’ve delivered beautiful products – patio door and 3 windows.  It was a pleasure to work with Tom, who measured and installed the products without a hitch.

You did a marvelous job helping me out to pick the color for the trims and I love the windows you suggested.  They are beautiful and covering them with curtains would be a shame.

I would highly recommend your company to people I know.
– Rosalind L.

We were very pleased with the quality, price and customer care that we received when replacing our old windows.  We would recommend Advanced Windows & Siding, Inc. to a friend and would (and have) use again.
– Lori C.

Thanks so much for helping us with our windows.  Please tell Tom and the rest of the workers that they did a terrific job!  The windows look amazing.  The trim around the windows turned out perfect and we couldn’t be happier.

I can’t rave enough about these beautiful doors.  The installation was so professionally done and finished in a short time.  My house looks like new and I am thrilled!  What a great company to deal with and I thank you for that!  I think you can tell how pleased I am! Thanks again!

Great job by your guys getting the windows installed.  They look great.  Appreciate your help and response.
– Mike F.

I love my new windows! I was referred to ADVANCED WINDOWS & SIDING by five friends and was not disappointed at all! They were most informative on the window product and kept me in constant progress of my order. The workers were professional and neat. I was amazed at how quickly they finished the job. The price was right and they did not request a down payment. I would highly recommend ADVANCED WINDOWS & SIDING…that’s why they have been in business for over 40 years!
– Judy H.

We absolutely love our new windows and have been really impressed by your dedication to excellent customer service.  It has been a real pleasure to deal with you.  You have made what could potentially be a stressful and frustrating experience into a positive and comfortable time.  Thank you so very much for pulling out all the stops to ensure we ended up with the look we had hoped for.

Your crew have been wonderful – they are such clean, efficient craftsman who ensures every little detail is taken care of.  Once again, Dave, the county inspector was full of praise for the quality of the windows and most especially for the high standard of workmanship which went into the installation.  So kudos to the install crew!

Thank you for all your help and kind advice Dennis – it’s been lovely to encounter such a genuinely nice guy who isn’t all about the sale!

We wish you every success for the future and are sure Advanced Windows & Siding, Inc. with thrive and prosper – you certainly beat the big boys and the cowboys hands down!

Sincere regards,
– Mo and Andrew B.

The door looks great – Thanks!  We appreciated your efforts throughout the process.
