Fiber cement siding cost in Pennsylvania: what you actually pay for
By the D&E Mako Renovation crew, Ephrata, PA. General guidance, not a quote for your house.
Fiber cement siding costs more than vinyl and less than real wood or stone. National cost guides put it at roughly $5 to $14 per square foot installed, which works out to somewhere between about $8,000 and $27,000 for a typical house, with the average whole-house job around $15,000 (This Old House, Fixr). That is a wide range, and the reasons for it are worth understanding before you collect quotes.
We install a lot of fiber cement, most of it James Hardie lap siding, on old stone houses with frame additions, ranches and new houses. This guide explains where the money goes on a fiber cement job, why two quotes for the same house can be thousands apart, and what you get for the extra money compared to vinyl.

When a contractor quotes per square foot, that number usually rolls together several things. It helps to pull them apart.
The siding itself. Fiber cement boards are a mix of cement, sand and wood fiber. Plain primed lap boards are the cheapest part of the job. Pre-finished boards with factory paint (James Hardie calls it ColorPlus) cost more per board but save you a paint job later. Specialty profiles such as shingle panels, board and batten, and thick architectural panels cost more again.
Trim. Corner boards, window and door casings, frieze boards, band boards and fascia. On a simple ranch the trim is a small share of the job. On an older two-story house with many windows, the trim can be a third of the labor.
Housewrap and flashing. Behind the siding goes a water-resistant barrier. Every window and door needs flashing tape and a head flashing. Fiber cement butt joints get a strip of flashing behind them. These materials are cheap. The time to install them properly is not.
Removal and disposal. Taking off old siding, especially old aluminum or asbestos-cement shingles, adds labor and dumpster cost. Asbestos shingles must be handled by a licensed abatement contractor, which is a separate line.
Sheathing repair. This is the unknown. Nobody can tell you exactly how much rotten sheathing is under old siding until it comes off. A fair quote includes an allowance for it and a price per sheet for anything beyond the allowance.
Labor. Fiber cement is heavy and has to be cut with special blades and dust control. It goes up slower than vinyl. Labor is usually the largest single part of the price.
Why quotes for the same house vary so much
If you collect three quotes for fiber cement on one house, it is common to see a gap of 30 percent or more between the lowest and highest. Some of that is overhead and profit. Most of it is scope. Here is what to compare.
Does the quote include taking the old siding off?
Some installers quote fiber cement over the existing siding to keep the price down. That hides rot, makes window trim look sunken and can conflict with the manufacturer's installation rules. If one quote is much lower, check whether it skips removal. We explain why removal matters in should old siding be removed before new siding.
How is trim handled?
There is a big difference between new PVC or fiber cement trim around every window and simply running the siding up to the old wood trim and caulking it. The second is cheaper today and costs you later, when the old trim rots behind the new siding.
What is the sheathing allowance?
A quote with no sheathing allowance is either padded or will grow once the walls are open. Ask what the allowance covers and what each extra sheet costs.
Is the siding primed or pre-finished?
Primed fiber cement must be painted after install, which is either in the quote or a separate painter's bill. Factory-finished boards cost more up front and carry a longer finish warranty. Make sure you are comparing like with like.
How high and how cut up is the house?
A single-story ranch with long plain walls is fast. A two-story colonial with dormers, gables, bay windows and a porch needs staging, more cuts and more trim. Gambrel and steep gable ends like the ones on the stone house in Lower Merion we sided in 2025 take much longer per square foot than a flat wall.

Rough installed ranges from national cost guides, so you can see where fiber cement sits:
| Siding | Typical installed cost per sq ft | Notes |
|---|---|---|
| Vinyl | Lowest | Fastest to install, thinnest look |
| LP SmartSide engineered wood | Low to middle | Wood look, must keep cut ends sealed |
| Fiber cement (James Hardie and others) | About $5 to $14 | Does not rot, holds paint, heavier to install |
| Cedar shake or clapboard | Middle to high | Beautiful, needs finish care |
| Stone or brick veneer | Highest | Usually used as accents |
The cheaper materials are not wrong choices. On a rental or a garage, vinyl or LP SmartSide often makes more sense. We compare them in detail in fiber cement vs vinyl vs LP SmartSide.
How long fiber cement lasts
Fiber cement does not rot, does not feed insects and does not melt. James Hardie backs its lap siding with a 30-year limited warranty, and properly installed fiber cement commonly lasts 30 to 50 years. The paint is the part that wears. Primed boards painted on site typically need repainting every 10 to 15 years. Factory finishes last longer.
What shortens the life of fiber cement is almost always installation:
- Too close to the ground or the roof. Fiber cement needs clearance above grade, above roofs and above decks so the bottom edge does not sit in water.
- Unflashed butt joints. Where two boards meet end to end, a piece of flashing behind the joint keeps water out of the wall.
- Uncoated cut ends. Cut ends should be sealed or primed so they do not soak up water.
- Face nailing in the wrong spot. Nails need the right size, spacing and depth or boards crack.
These are the details in the manufacturer's install guide, and they are what keep the warranty valid.
What raises the price on Pennsylvania houses specifically
Houses around here have a few things in common that affect fiber cement jobs.
Stone and brick next to frame. Many older houses in Lancaster, Chester and Montgomery Counties are part stone and part frame. Where siding meets masonry, the joint needs careful flashing and trim, and the stone is never straight. That adds time.
Old aluminum and asbestos shingles. Post-war houses often have aluminum siding or asbestos-cement shingles. Aluminum comes off easily. Asbestos needs a licensed abatement crew before we start.
Freeze and thaw. Pennsylvania winters push water into every gap and freeze it there. That is a good reason to choose fiber cement, and a reason to get the flashing right.
Townships and historic districts. Most siding replacement does not need a permit, but some boroughs and historic districts review exterior changes. Check before you order.
How to read a fiber cement quote
A good quote for fiber cement siding should tell you:
- Which walls are included, with square footage.
- Whether old siding is removed and how it is disposed of.
- The siding brand, profile, exposure and whether it is primed or factory finished.
- The trim material for corners, windows, doors and frieze.
- The housewrap or barrier and how windows and doors are flashed.
- The sheathing repair allowance and the price for extra sheets.
- Gutter removal and reinstallation, if needed.
- Painting, if primed boards are used.
- A rough schedule and how the house is protected overnight.
If a quote is missing several of these, ask. The answers usually explain the price difference.

- Do the visible sides first. Some homeowners do the front and the most weathered side now and the rest later. It works if the boards and color are still available.
- Use simpler profiles. Plain lap siding costs less than shingle panels or thick architectural boards. Use the fancier profile only on gables.
- Pick primed boards if you have a painter you trust. Factory finish is convenient, but primed boards painted by a good painter can be cheaper.
- Plan around windows. If windows need replacing soon, do them with the siding. Replacing windows later means disturbing new trim.
- Avoid change orders. Decide colors, profiles and trim details before work starts.
Is fiber cement worth it?
On a house you plan to keep for ten years or more, usually yes. It looks like painted wood, it does not rot, and it is one of the few exterior upgrades that tends to hold its value. On a house you plan to sell soon, or a garage or rental, a cheaper material may make more sense.
If you want a real number for your house rather than a range, that takes a visit. We look at the walls, pull a piece of siding where water usually gets in and give you a written estimate with each item listed. See our siding service page for how we work, and the Lower Merion siding project for an example of fiber cement lap siding and cedar shake on an older house.
