Impact Window Retrofit Installation Tips, Cost Analysis & Guide

  • Retrofit installation is often more cost-effective than full window replacement.

  • Impact windows are a vital safety feature for homes in storm-prone areas.

  • Proper measurements and structural integrity are crucial before installation.

  • Material and labor costs can vary, but upfront investment leads to long-term savings.

  • Choosing the right impact window involves considering factors like size, style, and ratings.

Why Opt for Impact Window Retrofits?

Imagine a baseball flying towards your window at high speed. Now imagine that same scenario during a hurricane with debris being the projectile. Scary, right? This is where impact windows come into play. They're designed to withstand such forces, keeping you and your home safe. Besides that, they can also provide energy savings, noise reduction, and UV protection. Most importantly, retrofitting existing windows with impact-resistant ones is a smart move if you're looking to upgrade without the hefty price tag of a full window replacement.

Defining Impact Windows and Their Benefits

So, what exactly are impact windows? They are windows made with a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) sandwiched between two panes of glass. This construction allows the window to absorb impact without shattering into dangerous shards. But the benefits don't stop at safety. Impact windows can also:

  • Reduce energy costs by providing better insulation.

  • Decrease outside noise for a quieter home environment.

  • Protect against UV rays that can fade furniture and carpets.

  • Improve home security against break-ins.

Comparing Retrofit vs. Full Window Replacement

When it comes to upgrading your windows, you have two main options: retrofitting or full replacement. Retrofitting involves installing new impact-resistant glass into the existing frames, while full replacement includes removing the old frames and installing entirely new units. Here's the deal: Retrofitting is typically less invasive and more cost-efficient. On the other hand, full replacement might be necessary if your existing frames are damaged or if you want a completely new look.

Pre-Installation Assessments

Before you dive into the world of impact window retrofitting, you need to do some homework. That starts with two critical steps: ensuring accurate measurements and checking the structural integrity of your current window frames. Getting these right means the difference between a snug, secure fit and a potential disaster.

Ensuring Proper Measurements

First things first, measure your windows. Twice. Maybe even three times to be sure. This isn't just about height and width; you'll also need to consider the depth of the window opening. This ensures that the new impact glass fits like a glove. If measuring seems daunting, don't hesitate to call in a professional. Accurate measurements are the foundation of a successful retrofit.

Structural Integrity Checks

Next, inspect your existing frames for any signs of damage or rot, especially if you live in an older home. Retrofitting with impact windows won't do much good if they're set in frames that can't hold their own. If you find issues, address them before installation to ensure your home is as secure as it can be.

Understanding Retrofit Window Costs

Let's talk numbers. Retrofitting your windows with impact glass isn't pocket change, but it's an investment in your home's safety and value. To get a clearer picture, consider both the material expenses and the installation charges.

Calculating Material Expenses

The cost of the impact-resistant glass itself can vary based on:

  • The size of the windows.

  • The type of impact glass selected.

  • Any additional features like tinting or low-E coatings.

As a rough estimate, you're looking at anywhere from $35 to $50 per square foot of glass. Keep in mind that prices can fluctuate based on the supplier and current market conditions.

Estimating Professional Installation Charges

While some brave souls might consider DIY, professional installation is typically recommended for impact windows. Why? Because ensuring a perfect, airtight fit is crucial for them to function correctly. Installation costs can vary widely, but labor often runs between $150 to $400 per window. Remember, though, this investment pays off in the long run through energy savings, increased home value, and, most importantly, peace of mind during storm season.

Selecting the Right Impact Window

Choosing the right impact window is like picking a shield for your home. It needs to be strong enough to protect but still fit perfectly with your home's aesthetics. Here's what you need to look for:

  • Impact rating: Ensure the window meets the standards for your area's weather conditions.

  • Frame material: Aluminum, vinyl, and wood are common options, each with its pros and cons.

  • Style and size: The window should match the look of your home and fit the existing openings.

  • Energy efficiency: Look for windows with good insulation ratings to save on energy bills.

Don't forget to check for local building codes and insurance requirements. They can affect which windows you can install and may even offer discounts for certain types of impact windows.

Removing Old Windows Safely and Efficiently

Out with the old, in with the new. Removing old windows can be tricky, but it's essential to do it right to avoid damaging your home. Start by carefully taking off the trim and moldings to expose the window. If you're not comfortable with this step, it's best to let the professionals handle it. They have the tools and know-how to remove the window without leaving a scratch.

Pro Tip: Place a tarp or drop cloth inside your home under the window area to catch any debris or glass shards during removal. Safety first!

Once the window is out, clean the opening thoroughly. Any leftover debris can prevent the new impact window from fitting snugly, which is essential for its performance.

Incorporating Secure and Precise Fixing Techniques

Installing impact windows is not a slapdash affair. It requires precision and attention to detail. Here's what needs to happen:

  • Apply a waterproof membrane around the window opening to prevent water damage.

  • Install the window using heavy-duty screws designed for impact windows.

  • Seal around the window with high-quality caulking to prevent drafts and water infiltration.

These steps are crucial for the window to perform its best. If not done correctly, you could face leaks, drafts, and even window failure during severe weather.

Post-Installation: Ensuring Quality and Functionality

Once your new impact windows are in place, it's not time to relax just yet. A few critical checks are necessary to ensure everything is up to snuff.

Performing Pressure and Water Resistance Tests

After installation, your windows should be tested for pressure and water resistance. This can usually be done by the installation team. They'll check for air leaks and ensure that the window can withstand heavy rains without letting water seep in. If any issues are found, they need to be addressed immediately to maintain the integrity of the window.

Final Inspection Must-Haves

Your final inspection should be thorough. Check for:

  • Proper operation of the window – it should open and close smoothly.

  • Correct installation of locks and other hardware for security.

  • The absence of gaps or cracks in the sealing and caulking.

Don't hesitate to ask the installer to walk you through what they've done. A reputable installer will be happy to show off their work and answer any questions you have.

Tips to Maximize Window Lifespan

Now that your impact windows are installed, let's keep them in top shape. Here are some tips:

Regular Maintenance Habits

Regular maintenance goes a long way. Clean the glass with a mild soap and water solution, and lubricate the moving parts annually. Also, inspect the seals and caulking periodically and reapply if they're showing signs of wear.

Seasonal Preparations and Considerations

  • Before storm season, check that your windows are secure and that all locks are functioning.

  • Inspect the frames for any signs of corrosion or damage, especially if you live near the coast.

  • Consider adding window treatments for extra protection against UV rays and heat.

These small steps can extend the life of your impact windows significantly.
