🪟 What is Window Capping?

First things first, what exactly is window capping? Window capping, also known as window cladding or wrapping, is the process of covering the exterior wood trim of your windows with a durable, weather-resistant material. This protective layer acts as a shield against the elements, helping to prevent water damage, rot, and decay, while also enhancing the appearance and longevity of your windows.

Why Window Capping Matters


Now that you know what window capping is, let’s talk about why it’s so important for homeowners like you. Here are a few key reasons why window capping matters:


Window capping provides an extra layer of protection for your windows, shielding them from rain, snow, wind, and UV rays. This added defense helps prevent water infiltration and moisture damage, prolonging the lifespan of your windows and preserving the integrity of your home’s interior.


Capped windows are more durable and resistant to wear and tear than unprotected wood trim, meaning they’ll last longer and require less maintenance over time.

With window capping, you can say goodbye to issues like rot, decay, and insect damage, giving you peace of mind and saving you time and money on repairs.

Energy Efficiency

By sealing gaps and cracks in your window trim, capping helps improve energy efficiency by reducing drafts and heat loss, ultimately saving you money on heating and cooling bills.

With properly capped windows, you’ll enjoy a more comfortable indoor environment year-round, with fewer temperature fluctuations and lower energy costs.

Enhanced Curb Appeal

Window capping can give your home’s exterior a fresh, polished look, boosting curb appeal and increasing property value. Whether you choose a classic white finish or a bold color to complement your home’s style, capped windows add a touch of elegance and sophistication that catches the eye of passersby and potential buyers alike.

🛠️ The Window Capping Process in 6 Simple Steps


Now that you understand the benefits of window capping, let’s walk through the process of capping your windows step by step:

1. Assess Your Windows

Start by inspecting your windows to determine if they’re suitable for capping. Look for signs of damage, rot, or decay in the wood trim, and make note of any areas that may need repair before capping.

2. Choose Your Materials

Next, select the materials for your window capping project. Common options include aluminum, vinyl, or PVC coil stock, which come in a variety of colors and finishes to complement your home’s exterior.

3. Measure and Cut

Measure the dimensions of each window and cut the capping material to size using a saw or utility knife. Be sure to leave a slight overhang to ensure complete coverage and protection.

4. Prepare the Surface

Clean the exterior wood trim of your windows thoroughly to remove dirt, debris, and any loose paint or caulk. Sand down rough spots and fill in any cracks or holes with wood filler for a smooth, even surface.

5. Install the Capping

Starting at the top of the window, carefully apply the capping material over the wood trim, pressing it firmly into place. Work your way down the sides of the window, overlapping the edges of each piece of capping to create a seamless seal.

6. Secure and Seal

Once the capping is in place, secure it with nails or screws along the edges, being careful not to puncture the window frame. Finally, seal the edges and seams with exterior caulk to prevent water infiltration and ensure a watertight seal.
