Vinyl siding is one of the most popular exterior finishes in Canada. It is low-maintenance, durable, and cost-effective. Millions of homes use it because it holds up well in harsh weather and does not need painting.
Installing vinyl siding is not complicated, but it does require the right steps. Skip a step and the siding can buckle, warp, or let in water. Follow the steps in this guide and your installation will last for decades.
This guide covers everything: measuring, choosing materials, removing old siding, installing new panels, and maintaining them. Whether you are a homeowner doing it yourself or hiring a pro, knowing the process helps you get it done right.
Taking Accurate Measurements
Accurate measurements prevent waste and save money. Before buying any materials, measure every wall that needs siding.
Here is how to do it:
Measure the height and width of each wall. Multiply height by width to get the square footage.
Add up the square footage of all walls. Do not subtract windows and doors unless they are very large, like a garage door. The leftover material covers waste.
Measure the perimeter at the base of the house. This tells you how much starter strip you need.
Every 100 square feet is called one square. Order materials by the square.
Add 10% to your total to allow for cuts and waste, especially on rooflines with steep angles.
Choosing the Right Vinyl Siding Style and Color
Vinyl siding comes in many styles: horizontal lap, vertical, Dutch lap, beaded, and board and batten. Each style creates a different look. Horizontal lap is the most common. Vertical siding works well on gables and accent walls.
Thickness matters too. Thicker panels, typically 0.044 inches or more, resist impact better and hold their shape in extreme heat or cold. Thinner panels cost less but dent and warp more easily.
For color, choose a shade that matches your roof and trim. Dark colors absorb more heat and can distort if the panel is thin. Lighter colors show less fading over time. Most manufacturers offer a lifetime color warranty on premium lines. Always request physical samples before ordering.
Removal of Old Siding
If you are residing over an old exterior, remove or prepare the existing material first. Do not install vinyl over rotted wood. It will only hide the damage and make it worse.
Follow these steps:
- Remove gutters, downspouts, light fixtures, and any other wall attachments.
- Use a zip tool or pry bar to remove old siding panels from the bottom up.
- Inspect the sheathing underneath. Replace any rotted or damaged boards.
- Nail down any boards that are loose or raised.
- Scrape away old caulk around windows and doors.
- Install furring strips on any uneven sections to create a flat surface for the new siding.
Tools and Materials Needed
Gather everything before you start. Stopping mid-job to find tools slows you down and causes mistakes.
Tools:
- Tape measure and chalk line
- 4-foot level
- Tin snips and utility knife
- Circular saw with a fine-tooth blade (installed backwards for cleaner cuts)
- Claw hammer
- Snap lock punch and nail slot punch
- Safety goggles
Materials:
- Vinyl siding panels
- Starter strip
- J-channel and undersill trim
- Inside and outside corner posts
- Water-resistive barrier (house wrap)
- Code-compliant flashing
- Corrosion-resistant nails (aluminum or galvanized steel, minimum 1-3/4 inches)
Installing Vinyl Siding: Step by Step
Work from the bottom of the wall to the top. Start at the back of the house and work toward the front. This keeps lap joints facing away from the street.
Step 1 — Apply the water-resistive barrier.
Wrap the entire wall with house wrap before installing anything else. Overlap seams by at least 6 inches. Install flashing around every window, door, and roof intersection.
Step 2 — Snap a chalk line.
Find the lowest point of the wall. Measure up 1/4 inch less than the width of your starter strip and snap a level chalk line around the entire house. This line must be level. Everything depends on it.
Step 3 — Install the starter strip.
Align the top edge of the starter strip with the chalk line. Nail every 10 inches. Leave 1/4-inch gaps between sections for expansion. Do not nail tight.
Step 4 — Install corner posts and J-channel.
Set the corner posts plumb and hang them from the top, nail in the uppermost slot. Nail the rest into the center of each slot, every 8 to 12 inches. Leave a 1/4-inch gap at the top for expansion. Install J-channel around all windows and doors.
Step 5 — Hang the first siding panel.
Snap the bottom of the first panel into the starter strip. Nail into the center of each slot. Never nail through the face of the panel. Leave 1/4 inch where the panel meets corner posts and J-channel.
Step 6 — Continue up the wall.
Lock each panel into the one below it. Stagger lap joints between rows so they do not line up. Check alignment every few rows with a level. A small error early becomes a large one later.
Key nailing rules:
- Drive nails straight and level.
- Leave 1/32 inch (the thickness of a dime) between the nail head and the vinyl.
- Center nails in the slots. Never nail to the far left or right of a slot.
- Space nails 16 inches apart for horizontal panels.
- Never pull a panel tight when nailing. Let it hang loose.
Maintenance Tips
Vinyl siding is low-maintenance, but it still needs attention to last. Neglecting it shortens its life and leads to costly repairs.
Wash the siding once a year with a garden hose and mild soap. Work from top to bottom.
Check caulking around windows and doors every spring. Replace any that is cracked or missing.
Look for loose or cracked panels after major storms. Replace damaged pieces right away to prevent water from getting behind the wall.
Keep shrubs and trees trimmed away from the siding. Constant contact causes scratches and traps moisture.
Never use a pressure washer at close range. It can force water behind the panels.
