New siding is one of the highest-impact upgrades a Montgomery County home can get, it transforms curb appeal and protects the house from weather, and the biggest decision is the material. For most homeowners here it comes down to vinyl versus James Hardie fiber cement: vinyl for lower cost and easy maintenance, Hardie for premium durability and looks. Understanding the tradeoff makes the choice clear. Let us break it down.
This comparison reflects the exterior work we do through our siding and windows service, and siding demand climbs through late summer and fall, so now is prime time to plan.
The Two Options at a Glance
| Factor | Vinyl Siding | James Hardie (Fiber Cement) |
|---|---|---|
| Cost/sq ft (installed) | ~$7–$14 | ~$12–$22 |
| Upfront cost | Lowest | ~1.5–2x vinyl |
| Lifespan | ~20–40 years | ~30–50 years |
| Durability | Good; can crack/warp | Excellent; fire/rot/impact resistant |
| Maintenance | Low (occasional wash) | Low; repaint eventually |
| Look | Good, many colors | Premium, wood-like |
Vinyl Siding
Vinyl siding is the most popular and affordable choice: a PVC product that comes in a wide range of colors and profiles, installs relatively quickly, and needs little more than an occasional wash. For homeowners who want a fresh, protected exterior at the best price, quality vinyl is a strong, sensible option.
Pros: lowest upfront and installed cost, low maintenance, color baked in so it never needs painting, and a good look, especially in thicker, higher-grade profiles. Cons: less durable than fiber cement, it can crack or become brittle in extreme cold, warp or melt near intense heat, and fade over many years, and thin builder-grade vinyl shows its age sooner.
James Hardie / Fiber Cement
James Hardie is the leading brand of fiber cement siding, a dense composite of cement, sand and cellulose fibers that is far tougher than vinyl. It resists fire, impact, rot, insects and warping, stands up to weather and temperature swings, and delivers a substantial, wood-like appearance that reads as premium. It costs more and is more specialized to install, but it is built to last decades.
Pros: outstanding durability and longevity, fire and rot resistance, a high-end look that boosts curb appeal and resale, and a strong manufacturer warranty. Cons: higher upfront and installation cost, it is heavier and more involved to cut and install correctly (genuinely specialized work), and it will eventually need repainting, though far less often than wood.
Cost Comparison
| Scope | Vinyl | James Hardie |
|---|---|---|
| Cost per sq ft (installed) | ~$7–$14 | ~$12–$22 |
| Whole-house reside (typical) | $12,000 – $28,000 | $20,000 – $45,000+ |
Hardie typically costs about 1.5 to 2 times vinyl, from both the material and the more specialized labor. Note that siding is priced on wall area, not floor square footage, a two-story home has far more wall to cover than a ranch of the same footprint, and complexity (gables, corners, trim) and the condition underneath also move the number. These are planning ranges; the full breakdown is in our siding replacement cost guide, and an accurate price needs an on-site measurement.
Vinyl or Hardie? Get Both Priced.
The right siding depends on your home, your budget, and how long you plan to stay.

Free siding consultations across Gaithersburg, Germantown and all of Montgomery County.
Is Hardie Board Worth It?
For homeowners planning to stay a while or wanting an upgraded look, James Hardie is often worth the premium, even though it costs 1.5 to 2 times vinyl upfront. You get materially better durability, resistance to fire, impact, rot, insects and warping, a longer lifespan of roughly 30 to 50 years versus 20 to 40 for vinyl, and a premium, wood-like appearance that tends to lift curb appeal and resale. Fiber cement consistently ranks among the higher-return exterior projects.
Vinyl still makes strong sense when upfront budget is the priority, on a rental or shorter-term hold, or when quality vinyl already suits the home and neighborhood well. There is no wrong answer, only the right one for your budget, timeline and the look you want. We price both so you can compare the day-one cost against the longevity and appearance directly.
How Long Does Vinyl Siding Last?
Quality vinyl siding, properly installed, commonly lasts around 20 to 40 years, with better, thicker vinyl lasting toward the upper end and thin builder-grade fading and becoming brittle sooner. It is low-maintenance but not indestructible: over the years it can fade, crack in extreme cold, or warp near intense heat. James Hardie, by comparison, commonly lasts 30 to 50 years and resists those failures, which is the core of the cost-versus-longevity tradeoff. For both, installation quality and a sound weather barrier underneath matter a great deal to how long the siding performs.
What's Underneath: House Wrap
A siding job is only as good as what goes on under it. House wrap is a weather-resistant barrier applied over the sheathing, beneath the siding, that keeps wind-driven rain and moisture off the wall structure while letting vapor escape so walls can dry. Siding alone is not a perfect moisture barrier, some water gets behind it, and the house wrap is what protects the sheathing and framing from rot, mold and energy loss.
When you reside, it is the right time to inspect and usually replace the house wrap and to address any damaged sheathing, because it is hidden and inaccessible once new siding goes on. Doing this properly, along with careful detailing around windows and doors, is a big part of what separates a siding job that protects the home from one that only looks new on the surface. It is also exactly the kind of work that is easy to skip on a cheap bid and expensive to fix later.
Siding ROI & Value
New siding is consistently one of the higher-return exterior improvements, because it transforms curb appeal and signals a well-maintained, protected home. Fiber cement in particular tends to rank near the top of exterior projects for resale return thanks to its premium look and durability, and quality vinyl also returns well at a lower upfront cost. Beyond resale, new siding protects against moisture and weather and can improve energy efficiency, real value even if you are not selling. The exact return varies with material, workmanship, the neighborhood and market, so it is not guaranteed dollar-for-dollar, and a professionally installed job with a sound weather barrier is what protects that value. We are contractors rather than appraisers, so for a precise read on your home, a local real estate professional is the right source.
Which Fits Your Home?
- Choose vinyl for the lowest upfront cost, low maintenance, and solid value, a smart choice on a tighter budget or a shorter-term hold.
- Choose James Hardie for maximum durability, the longest lifespan, a premium wood-like look, and strong resale return, when the budget supports the upgrade and you plan to stay.
