Are you considering replacing your old, drafty windows with new, energy-efficient ones? You're not alone. Many homeowners are turning to window replacement as a cost-effective way to improve their home's comfort, value, and curb appeal. But how much does it cost to re-putty windows, and is it worth it? Let's dive into the details.
Understanding the Cost of Re-Puttying Windows
Before we discuss the cost, it's essential to understand what re-puttying windows entails. Re-puttying involves removing the old, worn-out putty that seals the window glass to the frame, and replacing it with new putty. This process can help improve the window's insulation, prevent drafts, and enhance its overall appearance.
Factors Affecting the Cost of Re-Puttying Windows
- Window Size and Type: Larger windows and unique window types (like bay or bow windows) may require more putty and labor, increasing the cost.
- Number of Windows: The more windows you need to re-putty, the higher the labor cost will be.
- Window Condition: If your windows are in poor condition or have significant damage, additional repairs may be necessary, increasing the overall cost.
- Labor Costs: The cost of labor can vary significantly depending on your location and the local economy.
Average Cost of Re-Puttying Windows
Now that we've discussed the factors affecting the cost let's look at some average costs. According to HomeAdvisor, the average cost of re-puttying windows ranges from $150 to $400 per window. However, this cost can vary significantly depending on your location and the specific details of your project.

Cost Breakdown
| Item | Average Cost |
|---|---|
| Putty | $5 - $10 per window |
| Labor | $145 - $390 per window |
As you can see, labor typically accounts for the majority of the cost. This is because re-puttying windows requires careful attention to detail and a certain level of skill to ensure a proper, long-lasting seal.
Is Re-Puttying Windows Worth It?
Given the cost, you might be wondering if re-puttying windows is worth it. In many cases, the answer is yes. Re-puttying windows can help improve your home's energy efficiency, reduce drafts, and enhance its overall appearance. Plus, it's often a more cost-effective alternative to full window replacement.
However, it's essential to consider the age and condition of your windows. If your windows are old or in poor condition, re-puttying may not be enough to address all of your concerns. In these cases, full window replacement might be a better option.

DIY vs. Professional Window Re-Puttying
If you're handy, you might be tempted to re-putty your windows yourself. While this can save you money on labor costs, it's essential to consider the potential risks. Improperly re-puttied windows can lead to drafts, water damage, and other issues. Plus, if you damage your windows during the process, you might end up spending more in the long run.
For these reasons, it's often a good idea to hire a professional window contractor. Professionals have the skills and experience necessary to ensure a proper, long-lasting seal. Plus, they can often spot and address other potential issues with your windows that you might miss.
In conclusion, re-puttying windows can be a cost-effective way to improve your home's comfort, energy efficiency, and curb appeal. However, it's essential to understand the factors affecting the cost and to consider the age and condition of your windows before making a decision. Whether you choose to re-putty your windows yourself or hire a professional, taking the time to do the job right can help ensure that your windows serve you well for years to come.
