Vinyl Siding

Standard vinyl is a hollow extruded PVC panel that locks to the course below it and is nailed through a slot into the sheathing. It is light, quick to install, available in every profile and colour, and the least expensive cladding on the market. Panel thickness matters more than people realize — heavier gauge holds its shape better, resists warping, and looks straighter across a long elevation. We do not install builder-grade thin panel because it is a false economy that shows within five years.

Insulated vinyl adds a shaped foam backer bonded to the panel. The practical differences are immediate: the panel is far more rigid, so it lies flatter and straighter on an uneven wall; it is significantly more impact-resistant, which matters directly in hail country; it deadens exterior sound; and it adds meaningful R-value to a wall assembly that in most older Calgary homes has very little.

The trade-off is cost — insulated typically runs a substantial premium over standard — and slightly more labour, since it is thicker and heavier to work. Whether that premium pays back depends on how long you are staying and how cold the wall currently is. For a 1970s or 1980s home with minimal wall insulation, the case is strong. For a rental being prepared for sale, standard vinyl in a heavier gauge is usually the rational choice.

One thing neither product does is take paint reliably, so colour is a permanent decision. Choose against the roof colour, the trim and the street rather than against a sample chip in a showroom, and look at the sample outdoors — Calgary's high-altitude light reads colour differently from indoor lighting.

Almost every siding failure we are called to fix turns out to be a failure of the layers behind the cladding. Siding is a rain screen, not a waterproof membrane — it sheds the bulk of the water and the assembly behind it manages the rest. That assembly is the water-resistive barrier, the flashing at every opening, and a drainage path that lets incidental moisture escape.

So when the old cladding comes off, we inspect. Sheathing gets checked for rot and delamination, particularly low on the wall, under windows, and anywhere a downspout has been discharging. House wrap gets checked for tears, for reverse laps where an upper sheet was tucked behind a lower one, and for whether it was ever properly integrated with the window flashing at all — in a lot of older Calgary construction it was not.

Window and door openings are the highest-risk detail. Head flashing above openings is frequently missing entirely on homes built before it became standard practice, and the sill pan below is missing more often still. Both are cheap to add with the wall open and effectively impossible to add later.

Then the transitions: where cladding meets the roof, where it meets the foundation, where two materials meet at a storey line, and where a deck ledger penetrates the wall. Those junctions are where water actually gets in, and they are what we photograph and show you before covering them up.

Doing this correctly during a re-side costs a fraction of what it costs afterwards. Once the new cladding is on, reaching that layer means taking it all off again — which is the strongest argument for using a contractor who inspects before quoting rather than pricing from the curb.

Vinyl moves. A twelve-foot panel changes length measurably between a February morning at minus thirty and a July afternoon at plus thirty, and the entire installation method exists to accommodate that.

Fasteners go in the centre of the nailing slot, not the end, and are driven so the panel hangs rather than clamps — roughly a credit-card thickness of play between the nail head and the flange. A nail driven tight turns a floating panel into a fixed one, and the panel will buckle at the first hot week or split at the first deep cold.

Ends need clearance. Panels are cut short of the receiving channel by a specified amount — more in cold weather than warm, because the panel is at its shortest when you install it in winter and will grow. Butted tight, it has nowhere to go but outward, which is the visible waviness people call oil-canning.

Starter strips have to be level, because every course above inherits the error. Corners, J-channel and window surrounds have to be set so water sheds outward at every junction rather than being caught behind a flange. And on gables and high elevations, the panel needs enough fastening frequency to resist chinook uplift without being over-fastened.

None of this costs extra material. It costs attention, and it is the whole difference between a vinyl exterior that looks straight in fifteen years and one that looks wavy in three.

Vinyl's weakness in this region is impact in cold weather. PVC becomes progressively more brittle as temperature drops, so a hailstorm in May or September does far more damage to vinyl than the same storm in July. Damage shows as cracks and punctures, usually on the lower half of a panel where it is least supported, and usually concentrated on the elevation facing the storm.

That damage is frequently missed. A homeowner files a hail claim for the roof, the adjuster approves the roof, and the siding never gets inspected — until the house is sold and a home inspector lists every cracked panel. If hail hit hard enough to bruise your shingles, it very likely hit the walls facing the storm.

Cracks in vinyl are also easy to miss visually because they are hairline and only show in raking light. We inspect the walls at the same time as the roof, photograph what we find, and include it in the same claim scope — which is materially easier for an adjuster to approve than a separate submission months later.

If you are re-siding in a high-exposure area, insulated vinyl is the meaningful upgrade: the foam backer supports the panel across its full face, which substantially raises the impact energy required to crack it. Where hail exposure is the dominant concern and budget allows, fibre cement is the stronger answer, and we will tell you that rather than sell you the product with the better margin.

Vinyl siding is one of the most budget-friendly ways to reface a home, but the final price varies with the size and height of the house, how much trim and architectural detail it carries, whether you choose standard or insulated panels, and what condition the sheathing and barrier underneath turn out to be in. We quote after seeing the home in person so the number reflects your actual project rather than a guess.

The variables that move the price most: total wall area including gables, the number of storeys — a three-storey elevation needs staging that a bungalow does not — the number of windows, doors, corners and transitions, each of which is trim work rather than field work, and whether existing cladding has to come off or the house is a new build.

A typical Calgary bungalow re-side runs a few days on site; a large two-storey or an acreage home with substantial gable area takes a week or more. Weather is the wildcard, since vinyl is best not installed in deep cold when it is brittle and hardest to cut cleanly.

Disruption is modest compared with roofing. There is noise, there are ladders or scaffolding around the house, and interior wall vibration when fasteners go in, but you can live normally throughout. We protect landscaping, keep the site tidy daily, and finish with a full cleanup and walkthrough.

Re-siding demand here clusters by era. Late-1970s and 1980s subdivisions — Ranchlands, Whitehorn, Marlborough, Beddington, Woodbine, Acadia, Pineridge — are on original or first-replacement cladding that has now taken forty years of high-altitude UV and gone chalky and brittle. Early-2000s suburbs are reaching the age where builder-grade thin panel has faded unevenly and cracked at the corners.

We work all of them, in every Calgary quadrant, and out through Airdrie, Chestermere, Cochrane, Okotoks, High River, Langdon, Strathmore, Crossfield, Carstairs, Didsbury, Olds, Innisfail, Red Deer, Sylvan Lake, Canmore, Beiseker, Three Hills, Drumheller, Nanton and Diamond Valley.

Acreage siding is a different specification again. A country-residential home has no neighbouring buildings breaking the wind, so driven rain and snow hit the wall assembly directly and far harder than on a sheltered city lot. Fastening frequency, flashing detail and material choice all shift accordingly, and we specify against the actual exposure rather than a standard detail.

And we side garages. Matching the detached garage to the house during a re-side costs far less than doing it as a separate job later, and it is what makes the back of a property read as finished rather than as an afterthought.
