When You Should Choose Single Hung Windows

Homeowners often choose single hung windows when replacing older windows that allow drafts, increase energy bills, or show signs of moisture problems.

Their straightforward window opening design works well across many home styles, especially when reliability, controlled airflow, and long-term affordability are priorities.

Common signs you may need single hung window replacement include:

  • Noticeable air infiltration around the frame
  • Rising cooling costs during warmer months
  • Difficulty opening or closing outdated window types
  • Visible water infiltration after heavy rain
  • Reduced natural light due to aging or inefficient glass

Single Hung vs. Double Hung Windows

From our experience, homeowners often compare single-hung vs. double-hung windows when planning a replacement project. While they look similar, they differ in operation, ventilation, maintenance, and cost.

A single hung window has a fixed top sash and a bottom sash that slides up to open. A double-hung window features two operable sashes, allowing the top and bottom to move independently for greater ventilation flexibility.

Single-hung windows offer reliable airflow, fewer moving parts, and are typically more budget-friendly. Double hung windows provide added ventilation control and easier interior cleaning with tilt-in sashes.

If you’re looking for a cost-effective, traditional option with excellent energy efficiency, single-hung windows are a smart choice. Our team at STL Windows & Doors can help you decide which style best fits your home and comfort goals.

Our Single Hung Window Installation Process

We’ve refined our process to ensure every ProVia Endure® single hung window is installed for long-term performance, energy efficiency, and lasting durability.

1) Free Consultation & In-Home Assessment

We start with a no-obligation estimate and on-site evaluation. During this visit, we review your existing openings, discuss ventilation and design preferences, and take precise measurements to ensure your new single hung windows fit perfectly.

2. Detailed Project Planning

Before installation day, we plan every detail, accounting for your home’s structure, exterior exposure, and water management needs. Because single hung windows feature a fixed top sash and operable bottom sash, precise alignment and leveling are critical for smooth operation and a proper seal.

3. Professional Installation

Our trained installers secure each window using manufacturer-approved methods, including integrated nailing fins for a tight, weather-resistant fit. We focus on insulation, flashing, and sealing to reduce air infiltration and maximize energy efficiency from day one.

4. Final Testing & Walkthrough

After installation, we test the operation of the bottom sash, confirm proper locking and sealing, and complete a final inspection. We’ll walk you through the finished project to ensure everything meets your expectations and performs exactly as it should.

Reviews From Satisfied Customers

5-Star Customer Review

“We can’t say enough good things about STL Windows and Doors. A few years back we found STL Windows and Doors through the recommendation from family members that raved about their service and products. STLW&D replaced all but one of our old windows at that time.”

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!
