How vinyl siding installation actually goes together

Every vinyl siding installation job is built in a specific order, and the layers you never see once the job is finished are what actually keep water out of the wall or roof. The diagram walks through it step by step.

How a Siding Wall Assembly Works

  1. Sheathing — the structural wall surface everything else attaches to
  2. Weather-resistive barrier — a wrapped membrane that stops bulk water while letting vapor escape
  3. Rainscreen gap — a drainage and drying space between the barrier and the siding
  4. Siding — the visible cladding, fastened over the furring strips
  5. Window flashing — tucked under the barrier above and lapped over the siding below, so water never gets behind it

About vinyl siding installation

Premium vinyl siding is the fastest way to a tight, low-maintenance exterior. Today's thicker panels come in clapboard, Dutch lap, board-and-batten and shake profiles and in colors that were not possible a generation ago. The projects shown on this site include CertainTeed Monogram vinyl siding, used to replace rotting wood clapboards and 1970s metal siding on Portland homes. Vinyl moves with temperature, so how it is hung matters as much as which panel you pick.

This page is part of our siding work, which lists typical price ranges and materials. Other related services: siding replacement, James Hardie fiber cement siding, window replacement, roof replacement.

What the job involves

  • Old siding is removed and the wall is checked for soft sheathing and past leaks.
  • House wrap and flashing go on first, with extra care around windows, doors and roof-to-wall joints.
  • Starter strip, J-channel and corner posts are set straight and level so every course lines up.
  • Panels are nailed in the center of the slots and left loose enough to expand and contract through a Maine winter and summer.
  • Trim is wrapped or replaced with low-maintenance millwork so there is nothing left to paint.

Signs it is time

  • You are tired of repainting wood clapboards every few years
  • The existing vinyl is faded, cracked, or loose after wind storms
  • The budget needs a whole-house result rather than one premium wall
  • You want an insulated panel to take the edge off drafty walls

What affects the price

  • Panel grade and thickness, and whether it is insulated
  • Profile: clapboard, Dutch lap, board-and-batten or shake
  • Amount of trim, soffit and fascia wrapped or replaced
  • Tear-off and sheathing repairs
  • House height and access

Every job is priced from a free on-site estimate, with a fixed-price written proposal before work starts.

Vinyl Siding Installation: Built to Move With a Maine Winter

Vinyl siding expands and contracts more than any other cladding we install — a full course can grow or shrink noticeably between a January cold snap and a July heat wave. Good vinyl siding installation is built around that fact from the first panel. Nailed wrong, it buckles, waves, or cracks its first winter; nailed right, it rides out decades of Maine's seasonal swing without a problem.

Why Vinyl Siding Is Installed to Move

Every panel is fastened through a nailing hem near its top edge, and that nail is driven to leave the panel able to slide slightly side to side — never nailed down tight against the wall. Each course also locks into the one below it and needs a small gap where it meets trim and corner posts, so the whole wall can expand and contract as a system rather than fighting itself.

Installed this way, vinyl siding handles Maine's temperature swing without buckling. Installed tight — a common shortcut — it looks fine the day it goes up and starts waving within a year or two as the panels have nowhere to go.

CertainTeed Vinyl Siding Lines

CertainTeed is one of the manufacturers whose vinyl siding we install, offering panel profiles from traditional clapboard widths to shingle- and shake-look panels for a more traditional Maine cottage or farmhouse appearance. Panel thickness, wind rating, and warranty terms vary by product line — we'll go over the specific spec sheet for whatever line fits your budget and the look you want.

Where Vinyl Still Needs a Real Weather Barrier

  • Vinyl siding is a rain-screen cladding, not a waterproof membrane — it's designed to shed most water while still letting some wind-driven rain get behind it at seams and penetrations.
  • The weather-resistive barrier underneath, not the vinyl itself, is what actually keeps that water out of the wall assembly.
  • That's why we never treat the WRB as an afterthought on a vinyl job, even though the finished panels look like a complete, sealed surface.

    We hired Cardinal Exteriors to reside our house and install all new windows, and it was a terrific experience from start to finish! Bob was one of the very best contractors we've ever worked with (and we've worked with many over the years). He was extremely responsive, helpful, respectful of wishes and concerns, and never pressured us in any way.

    Bob @ Cardinal Exteriors replace 26 windows and resided our office building in Westbrook in 2025. Being in the construction business, we understand how proposals sometimes come with change orders and surprises if not outlined up front. Bob and his team finished our job on schedule and actually below budget.

    CARDINAL EXTERIORS re-shingled my roof. Bob Proved to be Knowledgeable and Trustworthy. He was responsive to my questions and took the time to explain the materials being used and the steps they were taking to weatherproof the roof of my home. The work crew was polite and they cleaned up the job site at the end of each work day.
