What Is a Clerestory Window?
A clerestory window is a row of windows placed high up on a wall. They sit right below the roofline. The word originally described the upper level of a church that was clear of the lower roofs to let light in. Today, builders use them in modern homes to brighten up a dark room. Because they sit so high, they don't take up valuable wall space. You can still place tall furniture, bookcases, or large artwork on the wall below them. They give your home a unique architectural look while serving a very practical purpose.
Why These Windows Matter to You
The biggest benefit is natural sunlight without losing your privacy. Since they sit way above eye level, neighbors and people walking by can't see inside your house. This makes them perfect for rooms facing a busy street. They also do a great job with ventilation. If your clerestory windows open, they let trapped hot air escape. Heat naturally rises to the ceiling. Opening these upper windows creates a draft that pulls cool air into the lower part of the house. This natural airflow helps your HVAC & Climate Control system run less often during mild weather. It can actually lower your utility bills in the spring and fall.
Where You Will Find Them
You usually spot these windows in living rooms with vaulted or sloped ceilings. Mid-century modern homes feature them a lot. Builders also put them in other spaces where you want light but need privacy:
- Bathrooms over the shower or tub
- Garages above the garage door
- Kitchens above the upper cabinets
Sometimes clerestory windows span the entire length of a wall. Other times, you might just see a small cluster of two or three windows. They're also common in additions or sunrooms where a homeowner wants to maximize light without adding a skylight.
What to Watch Out For
Cleaning them is the biggest hurdle you'll face. You'll need a tall A-frame ladder or a long extension pole with a squeegee to wash the glass. If you hire a window cleaning company, expect to pay an extra fee because of the height. You also need to watch for leaks. Because they're exposed to harsh weather near the roofline, the seals can wear out over time. If a seal breaks, water will run straight down your interior walls and damage your paint. Make sure you look closely at these upper frames when you inspect your Windows & Doors each fall.
Replacement Costs and Upgrades
Replacing a clerestory window is trickier than replacing a standard bedroom window. Installers often need scaffolding or special ladders to reach them safely. This extra labor drives up the price. A normal window might cost 500 to 800 dollars to replace. A clerestory Window Replacement Cost typically runs 800 to 1500 dollars per window. Keep in mind that these ranges vary based on your location and the type of glass you choose. Many homeowners upgrade to motorized shades or remote control openers. Since you can't easily reach them, a remote control lets you open the glass or close the blinds with the push of a button. Adding a motor can add 300 to 600 dollars to the total cost.
