Replacing Boat Window Screen: A Step-By-Step Guide For Boaters

Boat window screens are essential for keeping out wind, spray, and rain, and can even reduce harmful UV rays. However, they don't last forever and will eventually need to be replaced. Replacing a boat window screen can be a tedious and labor-intensive job, but with the right tools and guidance, it can be a manageable DIY project. This article will provide a step-by-step guide on how to replace a boat window screen, ensuring a proper fit and avoiding common pitfalls.

Removing the old window

To remove the old window screen, you will need a flat-head screwdriver, a claw hammer, and a pair of scissors.

First, remove the screen from the window and place it on a flat work surface. If your window is still attached to the boat, you will need to remove the screws on the trim ring, both from the outside of the boat and the inside. This will allow the window to be pushed out of the opening.

Next, use a flat-head screwdriver to pry the window screen spline from the grooves around the edge of the frame. The screen spline is a cord, typically made of vinyl, rubber, or foam, which secures the mesh screen to the window frame. If your spline is wooden, it may be fixed to the frame with staples or nails. If so, use your screwdriver to pry out the staples, or a claw hammer to remove the nails.

Dispose of the old screen and the spline, unless the spline is flexible and can be shifted back into place. If you are reusing the spline, inspect it for any signs of damage. If it looks brittle or old, you will need to purchase a replacement.

Now that you have removed the old window screen, you can move on to the next steps of the replacement process: preparing the frame, cutting the new screen mesh, and attaching the new screen.

Measuring the window hole

Firstly, it's important to understand the different parts of the window. The jambs are the vertical sides of the window opening, and the sill is the horizontal bottom part. The trim refers to the decorative frame around the window. With that in mind, you can start taking measurements.

Use a tape measure to measure the width of the window opening. Measure between the jambs at three points: the top, middle, and bottom. Ensure you measure from the surface of the jambs and not the trim or parting beads. Write down the smallest of these three measurements, as this will be the width of your window opening.

Next, you'll want to measure the height of the window opening. Measure from the high point of the sill (the part closest to the inside of the window) to the top of the window opening. Again, take three measurements: one at the left side, one at the centre, and one at the right side. Record the smallest of these three height measurements.

Now, you need to measure the depth of the window opening. Ignore any pulleys or parting strips, as these will be removed during installation. There should be at least 3 1/4 inches of opening depth between the inside window trim and the outside blind stop strip.

Finally, it's a good idea to check if the window opening is square. Measure the diagonals of the window opening and compare the measurements. If there is a significant difference, your opening may be out of square, and you might need to adjust your measurements or consider a smaller window.

With these measurements, you can now order your replacement window screen, ensuring it fits securely into the window hole of your boat. Remember to provide the manufacturer with the opening size only, as they will make the necessary deductions for the final product.

Buying a new window

If you're looking to buy a new window screen, there are a few things you should keep in mind. Firstly, window screens are not a standard size, and can vary even by a fraction of an inch, so it's important to get the right measurements for your window. You'll want to measure the height and width of the window frame, and also decide on the type of screen mesh and frame you want.

There are several types of window screen mesh available, each with its own benefits. Here are some of the most common options:

• Fiberglass mesh: This is the most affordable and easy-to-install option. It comes in different colours, such as gray and charcoal/black.
• Aluminum mesh: This type of mesh is durable, resistant to sagging, and less visible than other materials. It comes in bright or charcoal/black finishes.
• Solar mesh: This type of mesh blocks heat, UV rays, and glare from the sun, helping to protect your curtains and carpets from fading.
• Pet-resistant mesh: This type of mesh is designed to withstand the weight and claws of pets, making it a good option if you have cats or dogs.

In addition to the type of mesh, you'll also want to consider the frame colour and hardware. Frame colours can include black, white, beige, almond, bronze, and silver, so you can choose one that matches your interior decor. As for hardware, you may need things like corner springs, pull tabs, acorn pointers, or plunger bolts, depending on your window type.

When buying a new window screen, you can either purchase the components separately or buy a window screen replacement kit, which includes the mesh, spline, and a spline roller tool. If you've never replaced a screen before, a kit can be a good option to ensure you have all the necessary parts.

Finally, you can choose to buy custom-made window screens, which are made-to-order based on your specific measurements and preferences. This option may be more expensive, but it ensures a perfect fit and can be worth it for the added convenience and peace of mind.

Installing the new window

Now that you have successfully removed the old screen mesh and cleaned the window frame, it is time to install the new window screen.

Before installing the new window screen, ensure that you have the right type of mesh for your boat window. The most common type is fiberglass mesh, which is inexpensive and easy to install. You can also opt for aluminum mesh, which is more durable and resistant to sagging.

Once you have the right mesh, follow these steps:

Step 1:

Lay the new screen mesh over the window frame, ensuring it overlaps the frame by a few inches on all sides. This will ensure a secure fit. Cut the mesh to size with scissors, leaving a little extra material to be trimmed later.

Step 2:

Use a clamp or tape to hold the mesh in place at the top and bottom of the frame. This will ensure that the mesh stays taut and wrinkle-free during the installation process.

Step 3:

Take your screen rolling tool and begin to push the mesh into the grooves of the frame. Use the convex wheel, which is grooved outward, to do this effectively.

Step 4:

Secure the mesh to the frame by pushing the spline into the channel using the convex side of the spline roller. Ensure that the mesh remains taut but not overstretched. You can place a heavy object in the center of the screen to help with this process.

Step 5:

Once the mesh is secured on two adjoining sides, remove the clamp or tape and continue to secure the remaining sides. If you notice any wrinkles or bulges, remove the spline and start again.

Step 6:

Trim the excess mesh along the new spline using a utility knife. Be careful to angle the blade away from the spline to avoid damage.

Step 7:

If you are using a wooden frame, take this opportunity to reinforce any loose joints, fasteners, or screws. This will ensure that your new window screen is securely attached.

Step 8:

Reinstall the new window screen into the window. Ensure that the screen is centered and fits properly.

Tips for success:

• Work on a flat surface to ensure accurate cutting and placement.
• Keep the mesh taut but not overstretched to avoid damaging the frame.
• Take your time and be careful not to cut or tear the mesh during the trimming process.
• If you're reusing the spline, ensure it's not brittle or damaged, as this can affect the security of the new mesh.

By following these steps, you will successfully install a new window screen for your boat, improving ventilation and keeping bugs at bay!

Finishing touches

Now that you have your new boat window, there are a few final steps to ensure a perfect finish. Firstly, check that the window is centred in the hole by using shims between the window and the bottom of the opening. This will ensure the window is straight and secure.

Next, you'll want to apply seal tape to the flange. Start by placing the window face down on a soft surface. Apply the seal tape to the flange, beginning at the middle of the window's bottom and overlapping the ends by around half an inch. Pull the backing off the tape.

To prevent the tape from sticking to the outside wall of the boat before you're happy with the window's final position, use a spray water bottle to mist the perimeter of the opening.

If your window has a sliding glass function, it may be easier to handle with the glass in the open position.

Now, carefully insert the window into the opening. This usually requires two people. Once you're satisfied with the window's position, one person should hold it in place while the other centres the clamp ring on the inside of the window. Screw the clamp ring into place using the screws provided.

Finally, install the screen by inserting it into the screen track and pushing and pivoting it into place.

And there you have it! You've successfully replaced your boat window.
