1.2 Removing Existing Siding (If Applicable)

If you’re replacing existing siding, the first step is to remove it. This can be a time-consuming process, but it’s essential for creating a clean and even surface for your new siding. Here’s how to do it:

1. Safety First: Wear safety glasses and work gloves to protect yourself from flying debris and sharp edges.
2. Start at a Seam: Use a siding removal tool (or a flat pry bar) to gently lift the siding at a seam. This will expose the nails or screws holding it in place.
3. Remove Fasteners: Use a hammer and nail punch or a screwdriver to remove the nails or screws. Be careful not to damage the sheathing underneath.
4. Work Your Way Across: Continue lifting the siding and removing the fasteners until you’ve removed the entire section.
5. Dispose of Old Siding: Properly dispose of the old siding according to your local regulations.

Once you’ve removed all the old siding, inspect the sheathing underneath for any damage. Repair any rotten or damaged areas before proceeding. This is a crucial step to prevent moisture problems and ensure the longevity of your new siding.

1.3 Inspecting and Repairing Sheathing

With the old siding removed, you have a clear view of the sheathing. This is your opportunity to address any underlying issues that could compromise the integrity of your new siding. Look for these common problems:

• Rot: Soft, crumbling wood is a sign of rot. This is often caused by water damage.
• Mold: Black or green discoloration indicates mold growth. This can be a health hazard.
• Insect Damage: Holes or tunnels in the wood may indicate insect infestation.
• Loose or Missing Sheathing: Make sure all the sheathing is securely attached to the framing.

To repair damaged sheathing:

1. Remove Damaged Sections: Cut out the damaged sections of sheathing using a saw. Extend the cut beyond the visible damage to ensure you’re removing all the affected wood.
2. Install New Sheathing: Cut new sheathing to fit the opening and nail it securely to the framing. Use the same type and thickness of sheathing as the original.
3. Treat with Wood Preservative: Apply a wood preservative to the new sheathing to help prevent future rot and insect damage.

If the damage is extensive, you may need to consult with a professional contractor. Addressing these issues now will save you headaches (and money) in the long run.

1.4 Installing Underlayment (House Wrap)

Underlayment, also known as house wrap, is a critical component of a vinyl siding system. It provides a moisture barrier that protects your home from water damage. It also helps to reduce air infiltration, which can improve energy efficiency.

1. Roll Out the Underlayment: Start at a corner of your house and roll out the underlayment horizontally. Overlap each course by at least 6 inches.
2. Secure with Staples or Nails: Use staples or roofing nails to secure the underlayment to the sheathing. Space the fasteners about 12 inches apart.
3. Seal Seams: Use seam tape to seal the overlaps between courses of underlayment. This will create a continuous moisture barrier.
4. Cut Around Openings: Carefully cut the underlayment around windows, doors, and other openings. Leave a few inches of overlap to allow for sealing.
5. Seal Around Openings: Use flashing tape to seal the underlayment to the window and door frames. This will prevent water from seeping behind the siding.

Make sure the underlayment is installed correctly, as it’s your first line of defense against moisture intrusion. Pay close attention to sealing around windows and doors, as these are common areas for leaks.

Part 2: Installing the Trim

With the preparation work complete, it’s time to start installing the trim. The trim provides a finished look to your siding and helps to protect your home from the elements. This includes starter strips, corner posts, J-channel, and F-channel.

2.1 Installing the Starter Strip

The starter strip is the foundation for the first course of siding. It’s essential to install it correctly to ensure that the siding is level and secure.

1. Find the Lowest Point: Use a level to find the lowest point of your foundation. This is where you’ll start installing the starter strip.
2. Mark a Level Line: Use a chalk line to mark a level line around the perimeter of your house, about 1 inch above the foundation. This line will guide the installation of the starter strip.
3. Nail the Starter Strip: Align the top edge of the starter strip with the chalk line and nail it to the sheathing using roofing nails. Space the nails about 12 inches apart.
4. Overlap Starter Strips: Overlap the starter strips by about 1/2 inch at the corners.

Take your time to install the starter strip accurately. A level and straight starter strip is crucial for a professional-looking siding job.

2.2 Installing Corner Posts

Corner posts provide a finished look at the corners of your house and help to protect the edges of the siding. There are two types of corner posts: inside and outside corner posts.

1. Measure the Height: Measure the height from the bottom of the starter strip to the eave or soffit. Subtract 1/4 inch to allow for expansion and contraction.
2. Cut the Corner Post: Cut the corner post to the measured length using tin snips or a circular saw with a plastic-cutting blade.
3. Install the Corner Post: Slide the corner post over the siding and nail it to the sheathing using roofing nails. Space the nails about 12 inches apart. Make sure the corner post is plumb.
4. Overlap at the Bottom: Let the bottom of the corner post extend slightly below the starter strip to allow for water runoff.

Corner posts should be installed before the siding to provide a clean and finished edge. Make sure they are securely fastened to the sheathing.

2.3 Installing J-Channel

J-channel is used to frame windows, doors, and other openings. It provides a channel for the siding to slide into and helps to protect the edges of the openings from water damage.

1. Measure the Opening: Measure the height and width of the window or door opening.
2. Cut the J-Channel: Cut the J-channel to the measured lengths using tin snips or a circular saw with a plastic-cutting blade.
3. Miter the Corners: Miter the corners of the J-channel at a 45-degree angle to create a clean and finished look.
4. Install the J-Channel: Nail the J-channel to the sheathing around the window or door opening using roofing nails. Space the nails about 8 inches apart. Make sure the J-channel is flush with the opening.
5. Caulk the Seams: Caulk the seams between the J-channel and the window or door frame to prevent water infiltration.

Properly installed J-channel is essential for preventing water damage around windows and doors. Take your time to miter the corners for a professional-looking finish.

2.4 Installing F-Channel

F-channel is used along eaves and gable ends to hold the top course of siding. It provides a clean and finished look and helps to protect the edges of the siding from wind and rain.

1. Measure the Length: Measure the length of the eave or gable end.
2. Cut the F-Channel: Cut the F-channel to the measured length using tin snips or a circular saw with a plastic-cutting blade.
3. Install the F-Channel: Nail the F-channel to the sheathing along the eave or gable end using roofing nails. Space the nails about 12 inches apart. Make sure the F-channel is level and straight.

F-channel should be installed before the siding to provide a secure and finished edge at the top of the wall. Ensure it’s securely fastened to the sheathing.

Part 3: Installing the Siding

Now for the main event: installing the vinyl siding! This is where your patience and attention to detail will really pay off. Remember to take your time, follow the instructions carefully, and don’t be afraid to ask for help if you need it.

3.1 Cutting Vinyl Siding

Cutting vinyl siding accurately is essential for a professional-looking installation. There are several ways to cut vinyl siding, each with its own advantages and disadvantages.

• Utility Knife: For straight cuts, score the siding several times with a utility knife and then snap it along the score line. This is a good method for beginners.
• Tin Snips or Siding Shears: These are ideal for cutting intricate shapes and curves. They provide a clean and precise cut.
• Circular Saw: For long, straight cuts, a circular saw with a plastic-cutting blade is the fastest and most efficient option. Be sure to wear safety glasses and a dust mask. Cut with the finished side up to avoid chipping.

Always measure twice and cut once. It’s better to be a little too long than too short. You can always trim the siding down to the correct size.

3.2 Installing the First Course

The first course of siding is the most important, as it sets the foundation for the rest of the installation. Make sure it’s level and straight.

1. Lock into the Starter Strip: Insert the bottom edge of the first course of siding into the starter strip. Make sure it’s fully engaged.
2. Nail the Siding: Nail the siding to the sheathing through the nailing slots. Use roofing nails and space them about 16 inches apart.
3. Leave Expansion Gap: Do not nail the siding too tightly. Leave about 1/32 inch of space between the nail head and the siding to allow for expansion and contraction. The siding should be able to move freely.
4. Overlap Seams: Overlap the seams between siding panels by at least 1 inch. Overlap in the direction of water flow (i.e., with the higher panel overlapping the lower panel).

Pay close attention to the nailing technique. Overdriving the nails can damage the siding and prevent it from expanding and contracting properly. Underdriving the nails can cause the siding to come loose.

3.3 Installing Subsequent Courses

Once the first course is installed, the rest of the installation is relatively straightforward. Simply repeat the process for each subsequent course, overlapping the seams and nailing the siding to the sheathing.

1. Lock into Previous Course: Lock the bottom edge of the new course of siding into the top edge of the previous course. Make sure it’s fully engaged.
2. Nail the Siding: Nail the siding to the sheathing through the nailing slots. Use roofing nails and space them about 16 inches apart.
3. Leave Expansion Gap: Remember to leave a small expansion gap when nailing.
4. Stagger Seams: Stagger the seams between siding panels from course to course to create a more visually appealing look.

Use a siding gauge to help maintain consistent reveals between siding courses. This will ensure a uniform and professional-looking installation.

3.4 Working Around Windows and Doors

Installing siding around windows and doors requires careful attention to detail. The goal is to create a tight and weather-resistant seal.

1. Measure and Cut: Measure the distance between the J-channel and the siding and cut the siding to fit.
2. Notch the Siding: Notch the siding to fit around the J-channel. Use tin snips or siding shears to make the notches.
3. Slide into J-Channel: Slide the siding into the J-channel. Make sure it’s fully engaged.
4. Nail the Siding: Nail the siding to the sheathing through the nailing slots.

Caulk any gaps between the siding and the J-channel to prevent water infiltration. Use a high-quality exterior caulk that is compatible with vinyl siding.

3.5 Installing the Final Course

The final course of siding often requires some creative problem-solving. You may need to rip the siding to fit the remaining space.

1. Measure and Rip: Measure the distance between the F-channel and the top of the previous course of siding. Rip the siding to the measured width using a utility knife or a circular saw.
2. Slide into F-Channel: Slide the top edge of the siding into the F-channel.
3. Nail the Siding: Nail the siding to the sheathing through the nailing slots.

If the remaining space is too small to nail the siding, you may need to use utility trim to secure the siding.
