I would highly recommend using Mills Window and Door. We needed 3 windows replaced in our house…read moreand are very glad that we went with them. The free estimate was easy to schedule. The installation went smoothly, and the price was very reasonable. I really appreciated that they were responsive to all of my questions and were flexible when I needed to reschedule the installation date. They turned what could have been a very unpleasant process into something relatively easy. If I ever need a window replaced again, I will be calling Mills Window and Door.

I recommend homeowners do some research before working with this company. I found their business…read morepractices to be sketchy but do your own homework and decide for yourself. The company does not appear to be transparent. The website and rep claim their office is in Fenton but the business addresses registered with the Secretary of State are as follows: James & Kimberly Mills who filed articles of organization in 2015 (not 20 years ago as I was told by the rep) is at 438 E Clinton Place in Kirkwood. Another "Mills Window and Siding" company is registered with a fictious name located at 5355 Hagemann Crossing, Sunset Hills, MO 63128. I recently met with a rep from Mills Window and Door after getting a coupon in the mail. I was told the 40% coupon for siding would be from the "suggested manufacture price" and ultimately the bid would be competitive - so the coupon is merely a "bait and switch". I was told I would be paying 3% more if I used their "interest free financing" or a credit card. Mills Window and Door policy is to get 50% down but the work won't start for 2 months and they control the scheduling. When I questioned my concerns about paying 50% up front then having to be held hostage for at least 2 months to get the work done is not a benefit to me as a customer. One would hope a siding company would stock standard white siding. I was told they have been around for 20 years and have tons of great reviews. The original company was registered with Missouri Secretary of State in 2015. The "fictious company" was registered in 2022. Reviews can be manipulated as we all know and I would recommend homeowners get names and phone numbers from actual customers they have done work for in the past 3 months or don't use them. I informed the rep I would do my research to ensure I am dealing with the original company that has been around that long and he quickly skedaddled stating we were not a good fit. I agree.... I don't like working with companies who are not transparent and want to charge up front then not deliver the service for 2 months. I found the lack of transparency, multiple addresses and business practices unacceptable and felt it important to warn other homeowners to do your research and get actual recent referrals and bids from other companies.

The other gave quotes without doing any measurements. Clearview owner Marc made measurements and the a day later, sent in his window team to make exact measurements. I had all the exterior of my 1991 ranch completely redone. Upgraded polymer interlocking insulated vinyl siding with a moisture barrier wrap Tyvek underneath the siding. Brand new top grade soffet installed with new maintenance gutters. Also had them install an upgraded new front door. Huge difference with outside noise and temperature reduction.. Project was completed on time and on budget. Marc either called or showed up on the job site everyday. I have never dealt with a contractor professional of this caliber. Clearview should be your ONLY choice for sidings and windows in the St. Louis are. Thanks Marc!!

Updated Review, 7/5/2021…read more Another great install by Clear Window Technology! Clear Window Technology has installed four sliding glass doors and three exterior patio doors in two homes for us. All were installed incredibly well, by a great team... and are doors Made in USA, AND also Made in Missouri ! We highly recommend Clear Windows Technology! We also recommend having Clear Window Technology install for you doors from Target Windows & Doors, who are located in Vandalia, Missouri, which is near Mexico and Hannibal. The sliding glass doors are the Elite 4000 sliding glass door, with blinds installed between the panes - the blinds rise and fall by one slider, and tilt open/closed by another slider... on the stationary side and on the sliding door.  Dennis at Clear Window said this was the best door he offered and we agree it is great! The door slides so smoothly; the frame and door and locks are all solid. They even installed a foot lock that lets you prop the door open a few inches, to let in some air, while preventing it from moving until your toe taps to unlock the door. The three patio doors are hinged doors, and were installed with new wooden frames, to replace the original frame that had some wood rot. Clear Window Technology did a great job pre-sales, and for install, and the doors look great - nice and new and sleek and clean! Thank you, Dennis, Tracey!!! Original Review, 12/7/2017 Wonderful solid quiet smooth tightly sealed amazing and awesome & professionally installed were the first words I thought of when I got home and saw the amazing door that Clear Window Technology installed in our bay window. Our son also said - "This is a reallllly nice door!"  And he's right! We ordered the Elite 4000 sliding glass door.  It has the blinds installed between the panes.  Dennis at Clear Window said this was the best door he offered and we agree it is top notch. It is definitely tight and while our old door didn't seem to leak, we can tell that this one is keeping the cold air out better. The door slides so smoothly... it's just wonderful. The frame and door and locks are all solid. And they even installed a foot lock that lets you prop the door open a few inches, to let in some air, while knowing it can only be opened after your toe taps the lock. All of this, and to top it off, not only is it Made in America / Made in USA, but it's also Made in Missouri, by Target Windows & Doors, in Vandalia, which is near Mexico and Hannibal. Thank you to all at Target Windows & Doors for making such a fine door. Thank you to Dennis at Clear Window Technology for such a fine install, and for being an all-around professional in educating us on what to buy and getting it for us and for the nice install!

Absolutely no pressure, and just amazing service and professionalism throughout. Joe was incredibly patient while we decided on the right time to get started. As construction got underway, the team was respectful of our home and space, being careful to tidy up at the end of each day. They provided meaningful updates throughout, giving us opportunities for input while also offering their professional opinion on matters. When the unexpected would happen (as they do with a project of this size), we were so grateful for a reliable team to lean on. Things were taken care of, and done well. The attention to quality and detail cannot be matched, and that's coming from someone who is particular and picky. Joe and his team have been fantastic partners for this project. They really did make our remodel dreams come true.
