Peyton and Max installed 21 new windows and a new front door. They were a pleasure to work with, especially since we had other home improvement projects going at the same time. They did meticulous work and answered all of our questions.

I used Stl windows and doors to replace half of the windows in my house and a sliding door. The whole process was excellent. From talking with Dan, the sale manager to the installers (Tony and his crew ) to Scheduling with Chris at the office. First of all, Chris was able to up my schedule date a week early upon my request. I'm sure he squeezed me in his tight schedule. I was very thankful. Tony and his crew were very professional, yet friendly and considerate. They were prompt on time the 3 days they came and very efficient. They took down my window treatments and put them back up again exactly the way they were. They moved furniture and put back. They took the time to explain how the windows opened from top to bottom as the windows had many options that my old windows didn't have. I would use them again and would definitely recommend them to my family and friends

Worth the wait! Price was insanely different from other bids for a single window replacement. Paid cash for a slightly better rate. Originally was going to need to wait 8 months for replacement but I got lucky & they fit me in at the 4 month marker since they had a cancellation. Customer service from Kaleb & Tony was outstanding. Both were very personable & made me feel confident that the job was being done well. Great warranty! Glad to check this off my list:)

STL Windows and Doors did an excellent job with our window replacement project. We live in an older home (over 100 years old) and we know there are going to be issues related to its age. The STL Windows and Doors team worked extremely hard with us to replace one of our bathroom windows that had begun to show signs of water damage. After the initial window replacement project was finished, we did communicate with their team about concerns we had with the original window frame that remained. Chelsea worked with us and a team (Tony and Caleb) came to our house within a week and replaced the frame as well. Their prices were reasonable and they had an array of choices. Overall, we highly recommend them for any window-related project you may have!

Experience was great, STL W+D replaced our old rear door and transom with a new eight-foot unit. It’s great to have this huge pane of glass looking out over the back yard. Installers were great and clean and shimmied the door in without removing our old casing and messing with the plaster. They know what they are doing!

The removal of the old window and the installation of the new window went more smoothly than I would have expected. Peyton and Max were knowledgeable, professional, and completed the installation beautifully and efficiently. Both of them did a great job with making in the new window secure, sealed, and attractive.

Premium products and service at a more affordable price. Fantastic experience at every step of the process. Had some hail and tornado damage. Jared (sales) was friendly and knowledgeable about the industry. Did not hard sell, but instead provided a balanced and very detailed explanation of STL's products and services vs competitors, which felt trustworthy. Dan (owner) came out to measure the windows. My spouse said he was friendly and answered her questions. We got an unexpected scheduling break and installed much sooner than the expected wait. The installers, Peyton and Max, were friendly, efficient, and conscientious of our home. Their finish work (sealing and caulking) is better than the original for the house. They took the time to demonstrate all the features of the new windows and how to care for them. We all noticed a defect in the glazing inside one of the window sashes, which they immediately reported to the owner who, in turn, called me immediately about the manufacturer's quick replacement. Provia warrantees the vinyl, glass, hardware and screen of the window for life and this guarantee is transferable once to a new home owner. The installation has a 10-year guarantee. Also, STL has another business for window cleaning and screen replacement, which we're going to check out.

Great company to work with! We needed four hopper windows replaced on our garage/basement and STL Windows and Doors provided the best service and most competitive pricing. The work was done quickly and professionally, and everyone we met from the company was friendly. We would recommend calling them for your window needs!

  • Each window sash fits perfectly into the frame, with triple weatherstripping significantly reducing air leakage while improving your home’s insulation. If you’re considering how awning windows perform in different home styles, especially single-story layouts, check out our An Awning Windows Guide For Ranch Home Owners for more detailed insights.
  • These energy-efficient windows can significantly minimize heat transfer thanks to Low-E glass technology and argon gas fill. They are ENERGY STAR certified, indicating they adhere to the rigorous energy efficiency standards set by the U.S. Environmental Protection Agency. 
  • This keeps your home cool in the hot months and cozy when it’s cold, all while easing the workload on your HVAC system.
  • Triple-pane and double-pane glass options enhance insulation, further reducing energy consumption, making it perfect to applications like dormer window replacement.
  • In terms of security, these windows have a durable multi-point locking system engineered to ward off unauthorized entry, giving you a sense of security. The frames are sturdy and fortified to offer additional defense against break-ins.
  • Their build includes a polyurethane core and composite endcaps that boost energy efficiency and increase the window’s strength – doubling up as a protective feature.

TOP FAQ

Here are some frequently asked questions about these windows.  If you have other questions, please get in touch with us!

Casement windows are operated by turning a handle, which moves the window on its hinges, allowing it to swing open or close.

  • When the handle is turned, a metal arm mechanism, often called an operator, pushes the bottom of the sash outward while pulling the top inward.
  • The casement stay, a type of bar or metal arm attached to the bottom of the window, holds it in place when it’s fully open to prevent it from slamming shut due to wind.
  • For added security and weatherproofing, a multi – point locking system is engaged by a single lever; this draws the sash tightly against the frame’s sealing gasket.
  • High-quality weather stripping encircles the window’s perimeter ensuring that when closed, casement windows are sealed and extremely energy efficient.
  • They have an advantage over double-hung or single-hung windows because their seal can be tighter due to less movement of individual parts which results in better insulation from noise and outdoor temperatures.
  • Tensioning devices are sometimes included in modern designs so that even when open, casements remain steady and resist being moved by exterior forces like strong gusts of wind.

Yes, you can crank Provia Casement Windows open all the way for full ventilation because their design allows the entire window sash to swing out. Homeowners may select a non-washable casement hinge, which pivots closer to the frame, allowing
greater viewing area and better function for egress requirements.

Exploring the advantages and drawbacks of casement windows provides homeowners with valuable insight into their suitability for various home designs and personal preferences. Below is a comprehensive summary of these aspects presented in a table format.
