Many homeowners don’t realize how important basement windows are until they start to cause problems. Whether it’s letting in water during heavy rains or making your basement feel cold and damp, old windows can be more than just an eyesore. Knowing the replace basement window cost early on helps you plan better and avoid surprise expenses later. Basement windows protect your home from moisture, pests, and even help with air circulation and energy savings.
Replacing old or damaged windows improves your home’s safety, increases property value, and makes your basement feel more like a usable part of your home. Newer windows also look cleaner and are easier to maintain.
Common Reasons Homeowners Choose to Replace Basement Windows

There are many reasons why someone may choose basement window replacement. Some windows are old, rusted, or broken. Others may leak when it rains, or let in drafts during the winter. Many homes have steel-frame basement windows that are hard to open or close, and replacing them makes life easier.
Sometimes, homeowners want to upgrade from small, outdated windows to larger ones that let in more light. Some even switch to egress windows for safety, especially if the basement is used as a bedroom or living area.
Another reason is improving energy efficiency. Newer windows with better sealing help reduce heating and cooling bills. Plus, clean windows always improve curb appeal.
Replace Basement Window Cost: What You Should Expect to Pay
The cost to replace a basement window can vary based on size, material, and how complex the job is. On average, the basement window replacement cost ranges from $250 to $800 per window.
Here’s a simple breakdown:
- Basic small vinyl window: $250 – $400
- Glass block window: $300 – $600
- Egress window: $2,000 – $5,000 (including well installation)
If you need to replace multiple windows, some companies offer discounts. The overall cost to replace basement windows also depends on whether you need framing work, new sills, or repairs to surrounding areas.
Breaking Down the Labor Cost to Replace a Basement Window
Labor plays a big role in the basement window cost installed. While materials might cost a few hundred dollars, labor could double that amount depending on difficulty. On average, labor cost to replace basement window ranges between $100 and $300 per window.

It’s a good idea to get a few quotes from trusted contractors like Port Solutions DMV before moving forward.
Materials Matter: Cost of Basement Windows by Type
Different materials can affect your total cost. Here are some common types:
- Vinyl: Budget-friendly, weather-resistant, and low maintenance.
- Glass Block: Offers privacy and security but is less flexible with airflow.
- Wood: Classic and attractive but requires more maintenance.
- Steel: Very strong but can rust and become hard to open over time.
Each material has its pros and cons. The cost of basement windows will rise with custom options, higher-quality glass, or special coatings that block UV rays.
Special Cases: Crawl Space and Cellar Window Replacement
Replacing a crawl space window or cellar window can be tricky because of limited space and accessibility. These windows are often smaller and lower to the ground, and sometimes located behind landscaping or in tight corners.
The cost to replace a basement window in these spots can be slightly higher because of labor challenges. Also, many crawl space windows are made of older metal or wood frames that may need extra work to remove.
Using durable materials like vinyl or block glass is smart for these low areas, as they resist water and insects better.
Replacing Basement Windows in Cinder Block Walls

Many basements are built with cinder block walls, which require special tools and skills when it comes time for replacement. If you’re planning to replace basement window cinder blocks, expect labor costs to go up.
Working with concrete takes more time. Installers might need to saw through blocks, reinforce the opening, and re-seal everything to make sure it’s waterproof. That’s why replacing basement windows in cinder block homes can cost $400 to $1,000 per window depending on complexity.
Always make sure your installer has experience with this type of wall construction.
Basement Window Replacement vs. Full Installation
There’s a difference between simply replacing an old window and doing a full install. If the frame is still in good shape, basement window replacement might just involve swapping out the glass or sash.
But if you’re cutting a new window opening or expanding an existing one, that’s a full installation. This takes more time, planning, and money. New installations might also require permits, especially for egress windows or large expansions.
Discuss your goals with your contractor to find out if you need a simple replacement or a full window project.
How Much Do Small Basement Windows Cost to Replace?
Smaller windows cost less to replace, but prices still depend on the type and location. Most small basement windows cost between $200 and $500 to replace. This includes basic materials and average labor.
These are often hopper-style windows, which tilt inward and are common in older homes. If you’re replacing several at once, some companies may offer package pricing. Still, access, wall type, and window condition will affect the final quote.
Keep in mind that even though they’re small, these windows still need proper sealing and flashing to prevent leaks.
