Vinyl Siding Cost Calculator

Around $13,975 on an 1,800 sq ft single story house with one old layer stripped off — about $6.50 per square foot of wall — with most jobs that size falling between $11,475 and $17,325. Over bare sheathing with nothing to remove it is closer to $12,700, and a second story adds about 12% because the work is staged rather than laddered.

Yes, by about a third: $6.47 a square foot of wall against $9.64 on the same house. The question is how long you are staying. Vinyl lasts 20 to 40 years and needs only washing; fiber cement lasts 50 to 75 and needs repainting every 10 to 15. Selling within a decade, vinyl is the better arithmetic. Staying twenty-five years, fiber cement means buying one wall covering instead of two.

It was nailed too tight. Vinyl expands and contracts about a quarter of an inch over a 12 foot panel across a year, so it is designed to float — the nail goes through a slot and is left roughly a sixteenth of an inch proud, and the panel hangs on it and slides. Driven home, the panel buckles the first hot afternoon and stays buckled, and there is no fix short of taking it off. It is the most common installation fault in the trade and it is visible from the street.

Twenty to forty years, and the upkeep is washing it — no painting, ever, which is a large part of its appeal. What shortens it is impact rather than weather: vinyl is brittle in cold and cracks where fiber cement would dent, so in hail country it has a harder life. Fading is the other limit, and it affects dark colors more than light ones even with modern pigments.

For about 25% more it adds R-2 to R-3, which is not much energy — and it adds rigidity and quietness, which is what people actually notice. The foam backs the panel so it does not oil-can or wave, it sounds solid rather than hollow, and it reads much more like a wall and less like plastic. If the aim is for vinyl to look like a better material, that is where the money goes rather than into a thicker standard panel.

0.044 to 0.046 inch is the sensible range. 0.040 is builder grade and flexes visibly; above 0.050 is premium and holds its line best in wind. Thickness matters more than almost any other specification on a vinyl panel, because a thin panel oil-cans between studs and shows every imperfection in the wall behind it.

The part that actually keeps water out. Vinyl is a rain screen — it sheds most of the water and lets the rest drain and dry behind it — so the wall depends on the house wrap and the flashings underneath. The wrap has to be lapped shingle-fashion, and every window and door needs head flashing with the wrap lapped over it rather than tucked under. Done backwards, which is common, water runs behind the barrier instead of in front of it, and nothing about it is visible once the siding is on.

It can, it saves about 10%, and it is usually the wrong call. You never find out what is behind the old layer, which matters because re-siding is the only free inspection the walls will ever get. The house wrap and flashings underneath stay as bad as they were. And the extra thickness pushes the siding out past window trim that was not detailed for it, which is why sided-over houses look slightly wrong around the openings.

More than light vinyl, though far less than it used to — modern pigments are much better than the ones that gave dark vinyl its reputation. Dark panels also gain more heat, which means more movement, so the loose-nailing detail matters even more. Most manufacturers offer a lifetime fade warranty on their better lines, and those are worth reading specifically for what they exclude and whether they transfer to a buyer.

When you want the house to look like wood up close, because the overlap seams and the J-channel around windows read as vinyl to anyone paying attention. In hail country, where vinyl cracks and fiber cement dents. On a historic house, where it covers and sometimes damages what makes the house valuable and may not be permitted at all. And on a long horizon, where fiber cement at half again the price lasts more than twice as long.

Siding replacement recoups roughly 60 to 80% of its cost at resale for vinyl, which makes it one of the better exterior projects without being a money-maker. Its real value is that siding is the most visible single surface on the house: failing siding depresses offers out of all proportion to what fixing it costs, so sound vinyl removes an objection rather than adding a premium.

About 62 crew hours on an 1,800 sq ft house, which is a week for a small crew including stripping the old layer — the fastest of the common sidings, because panels are light, they interlock, and they hang loose rather than needing precise fastening. Weather moves it: the wall cannot be left open overnight in rain, so a wet week stretches the schedule.
