Siding

What siding costs
in the Lehigh Valley.

And when it's worth doing. Roofing and siding are both bread and butter here, and doing them together usually beats doing them a year apart.

The short version. Most siding jobs in the Lehigh Valley run $9,000 to $25,000 depending on the size of the house, which works out around $7 to $10 per square foot installed. Siding fails from the bottom up and the north side first, so if you're seeing warping or soft spots low down, that's where to look.

Cost

What siding costs by house type

Same logic as a roof. It's priced by surface area, so a number that covers a small ranch and a big colonial tells you nothing.

HouseTypical rangeNotes
Ranch or Cape$9,000 to $15,000Single story, simple walls, minimal cutting around openings
Two-story Colonial$15,000 to $25,000The common one here. More surface, more staging
Large or Complex$25,000 to $40,000Dormers, gables, multiple materials, heavy trim work
Partial or one elevation$3,000 to $8,000One wall, usually storm damage or rot repair

All include tear-off, house wrap, CertainTeed siding, trim, and disposal. Rotten sheathing is priced separately once the old siding is off, at a rate agreed before the job starts.

Siding options and material

What goes on the walls

Siding is mostly about the parts nobody photographs. What is behind it and how it terminates decides whether it lasts.

CertainTeed vinyl
The main line used here. Deep profiles, color that holds up, and panel lines that stay straight across a long wall instead of oil canning.
Insulated vinyl
Foam backed board behind the panel. Costs more, feels solid rather than hollow underfoot, and adds R value to a wall that usually has none.
House wrap and flashing
The layer that keeps water out. Siding sheds most of it, the wrap and the flashing handle the rest, and this is where most siding failures start.
Trim, soffit and fascia
Corners, J channel, window and door trim, and the underside of the eaves. Cheap trim is how a good siding job ends up looking like a bad one after two winters.
Doing it with the roof
The staging, the crew and the disposal are already on site, so siding and roofing together usually costs less than the same two jobs a year apart.
What is under it
Rotten sheathing behind old siding is common and it does not show until the wall is opened. Found, photographed and priced honestly rather than covered over.

Worth knowing

Do the roof and siding together

If both are near the end of their life, doing them in one go usually costs less than two separate jobs. One mobilization and one disruption instead of two.

It also means the colors get chosen against each other rather than one being matched to something you picked four years ago.

If only one of them is failing, we'll say so. There's no version of this where you get talked into siding you don't need because someone is already on site.

What fails first

Where to look on your own house

The bottom two courses
Siding fails from the ground up. Splashback, mowers and snow all hit the lowest boards hardest.
The north side
Least sun, slowest drying, most mold and moisture damage. Check it before the sunny side.
Around windows and doors
Failed caulk and flashing at openings lets water behind the siding, where you cannot see it working.
Soft or spongy walls
Press it. If it gives, water has been getting in long enough to rot the sheathing underneath.
Warping and buckling
Usually siding installed too tight. Vinyl needs room to expand, and when it cannot it buckles.
Rising energy bills
Often insulation and air sealing rather than the siding itself, but the two get fixed at the same time.

Straight answers

Questions we get asked

How long does siding take?

Three to five days for most homes.

Bigger or more complex houses run a week or more. Weather moves it, same as roofing, and it's better to move a start date than to install wet.

Can you match my existing siding for a repair?

Sometimes, and it gets harder the older the siding is.

Colors are discontinued and existing siding fades. On one elevation it usually works. Patching a single panel in the middle of a wall rarely looks right.

Is siding covered by insurance after a storm?

Often, yes. Hail and wind damage siding as well as roofs.

It's commonly missed on a claim because the adjuster is focused on the roof. If we're up there for storm damage anyway, the siding gets looked at too.

Do you insulate behind the siding?

It's an option, and it's worth pricing.

Insulated siding or a foam underlayment adds real R-value on an older house, and it's far cheaper to do while the walls are open than as its own project later.
