Double Hung Windows: What We’ve Learned Installing Them Across Utah, Idaho, Indiana, and Sacramento
Updated: November 10, 2026
Double-hung windows have two sashes that move vertically. They’re useful where you want to open the upper or lower sash and can comfortably reach both. Ask whether the model you’re considering has tilt-in sashes for cleaning. During a replacement estimate, check how each opening is used, whether the existing frame can stay, and what work the written quote includes.
We’ve installed double-hung windows in Draper, South Jordan, Midway and Riverton. This article is what we’ve learned from being in those rooms.
Key Takeaways
- Choose the window style by how the room is used, how easily you can reach the sash, and what you want to preserve about the opening.
- Ask whether the existing frame can accept an insert and how the installer will handle repairs if the frame needs to come out.
- Compare written installation scope, the exact window model and its whole-window ratings.
- Review grid, glass, screen, frame color and trim choices before placing the order.
Insert or Full-Frame Double-Hung Replacement
An insert fits inside an existing frame that is sound and suitable for the new window. A full-frame replacement removes the old frame and gives the installer access to the opening. Ask the installer to explain the method for each opening and how the new window will connect to the surrounding wall.
Ask how the chosen method will affect the visible glass, interior trim and exterior finish. If there are signs of water damage or a frame that has shifted, ask how the installer will investigate and price repairs.
What to Ask a Double-Hung Window Contractor
- Installation scope. Ask which existing parts stay, which come out, and who handles repairs, sealing and water management.
- Window specifications. Confirm the model, sash operation, screen, grids, glass package, finish and whole-window NFRC ratings.
- Finish work. Ask what the price covers for interior and exterior trim, disposal and cleanup.
- Warranty and changes. Get the product and labor terms in writing, including how added work is priced and approved.
If your project is in the Indianapolis area, contact the Indianapolis office to confirm service at your address.
How to Compare Energy Ratings for Double-Hung Windows
Compare the whole-window U-factor, solar heat gain coefficient and air leakage for the exact model and glass package. U-factor measures how readily heat passes through the window. Solar heat gain coefficient describes how much solar heat passes through it. Use the current ENERGY STAR criteria for your climate zone and ask how the installer will seal the opening.
Triple-pane glass was part of the specification for the Midway project below. Ask to see the NFRC label for the configuration in your own quote, including its frame, glass and operating style.
What Double Hung Windows Actually Do
Both sashes move vertically, so you can choose an opening at the top, the bottom or both. Tilt-in cleaning is available on some models. Try the locks, sash and tilt mechanism when comparing windows, especially for an opening above a counter or on an upper floor.
Three Projects That Showed Us When Double Hung Is the Right Call
Midway, Utah: When the Grid Pattern Is the Whole Story
The homeowner in Midway wanted to preserve the home’s appearance. We installed six double-hung windows with simulated divided lite grids and one picture window. The project used triple-pane ClimaTech TG2 with argon fill and a specified U-factor of 0.21 or lower.
South Jordan, Utah: Black Frames and a Mix of Window Styles
The 33-window South Jordan project used 13 double-hung windows alongside sliders, picture windows and custom arch shapes. Black exterior frames created contrast, and white interiors kept the finish consistent inside.
Draper, Utah: When Every Hardware Detail Points the Same Direction
The Draper project included 35 windows and sliding glass doors, including 16 double-hung windows. The Elite Series package used TG2 triple-pane glass, Arch Bronze exteriors and white interiors. The project also included obscure glass for privacy.
What a Real Consultation Looks Like: The Riverton Walk-Through
The Riverton project replaced 20 windows, including six double-hung windows, 12 two-lite sliders and two circle tops. The project used triple-pane ClimaTech TG2 with argon gas and a specified U-factor of 0.21 or lower.
Kitchen and Bath: Converted from Sliders to Double Hung
Two existing sliders in the kitchen and master bath were converted to double-hung windows. An upper sash gives the homeowner another way to open the window. At an estimate, check how easy it is to reach the sash from where you’ll stand.
Privacy and Sash Access
For a bath that faces a neighboring property, discuss sightlines with the installer. The sill height, sash opening and available privacy glass are all worth reviewing at the opening.
Front Living Room — Converted from Circle Top to 2-Lite Slider
In the front living room, the project replaced a fixed circle top with a two-lite slider. The new configuration added an operable window at that opening.
Where a Slider Can Fit
For a wide opening, try the reach and movement of a slider. Compare that operation with a vertically moving sash before choosing the configuration.
Choosing the Operating Style in Clinton, Utah
The Clinton project used 19 windows across four styles, including four double-hung windows, four two-lite sliders, nine picture windows and two casements. The mix shows how window use can vary room by room.
If the bottom sash provides the ventilation you need and the upper sash would be hard to reach, compare a single-hung window with the double-hung option. Try the controls and ask which sashes tilt on the specific models.
What We Actually Ask in Our Consultations
- What does this room need the window to do?
- Will furniture or a counter affect reach?
- Is privacy a factor on this side of the house?
- What exterior finishes should the frame color work with?
Rebates Worth Knowing
Before ordering, check your utility’s current eligibility rules for your address, the exact window, and the required paperwork. Ask for the model information and certification labels you’ll need to document the purchase.
Double Hung Windows: Frequently Asked Questions
What is a double hung window?
A double-hung window has upper and lower sashes that both slide vertically. Some models have tilt-in sashes for cleaning. Check how the exact model opens, locks and tilts.
What is the difference between single hung and double hung windows?
Both sashes open on a double-hung window. On a single-hung window, the lower sash opens and the upper sash is fixed. Compare reach, cleaning access and screen coverage on the models you’re considering.
Are double hung windows energy efficient?
Compare the exact window’s whole-window U-factor, solar heat gain coefficient and air leakage. The frame, glazing, operating style and installation all affect performance. Check the ENERGY STAR criteria for your climate zone.
How long do double hung windows last?
Service life varies with the product, exposure, installation and maintenance. Check how the sashes operate, inspect the frame and look for fogging between panes. Ask what parts can be repaired and what the warranty covers.
Are double hung windows good for ventilation?
Yes. You can open the upper sash, the lower sash or both. Compare the screen setup and how easily you can reach each sash from inside the room.
How do I know when it’s time to replace my double hung windows?
Fogging between the panes, drafts around a closed window, sticking sashes and frame damage are reasons to have the opening inspected. Ask whether the problem can be addressed through repair or whether the existing frame and window should be replaced.
Plan Your Double-Hung Window Replacement
Choose a style you can operate comfortably and get a written scope for each opening. If you’d like help reviewing the frames, glass and installation options in your home, schedule an in-home estimate.
