Siding is the single biggest visual decision you will make about your home. It covers more square footage than the roof, the windows and the doors combined. In Maryland, it also has to handle humidity that can hit 90 percent in July, freeze-thaw cycles in February, and the occasional hailstorm that rolls through Frederick and Howard counties every spring.
Two materials dominate the Maryland market right now. Vinyl and fiber cement. Each has a case. The right answer depends on how long you plan to stay, how much you want to spend, and what your neighborhood expects.
Vinyl still owns the majority of new siding installations in Maryland, and there are real reasons for that.
A typical 2,500 square foot home in Frederick runs 8,500 to 16,000 dollars for standard vinyl and 13,000 to 22,000 dollars for insulated premium vinyl. That is 30 to 50 percent cheaper than fiber cement for the same home.
The cost advantage comes with real tradeoffs.
The fade problem is the one homeowners underestimate. A blue or dark green vinyl home looks great at install. At year 12, the south wall is two shades lighter than the north wall, and the only fix is a full repaint with a bonding primer or a full replacement.
Fiber cement is a mix of portland cement, sand and cellulose fibers. James Hardie dominates the market in Maryland with Hardie Plank and Hardie Panel, and a few other brands sell smaller volume.
Fiber cement is heavier, more expensive and fussier to install.
Hardie Plank pre-painted with ColorPlus comes with a 15 year finish warranty. That is real money compared to repainting a 2,500 square foot home, which runs 6,000 to 10,000 dollars in Maryland.

Pure cost per year favors vinyl. The case for fiber cement is not that it is cheaper. The case is resale value, fire safety, humidity performance and the look of the finished home.
A lot of Maryland homeowners do not realize that the choice is not always theirs. Many neighborhoods in Columbia, Bethesda, Potomac and the upscale parts of Frederick County have covenants that require cement board or cedar siding and specifically prohibit vinyl. Some communities in Urbana and Spring Ridge require fiber cement on any home visible from a main road.
Check the covenants before you spec the material. A beautiful vinyl install that has to come back off is an expensive lesson.
Maryland is a humidity state. Summers regularly hit 80 plus percent relative humidity, and the moisture cycles through your wall assembly every day. Fiber cement handles this without issue because it does not rot, warp or feed organic growth.
Vinyl handles humidity fine too, but any moisture trapped behind it rots the sheathing underneath. A proper rainscreen installation with a ventilated gap behind vinyl solves this, but many installers skip it to keep costs low.
Freeze-thaw is the other factor. Maryland sees 40 to 60 freeze-thaw cycles per year depending on elevation. Fiber cement is unaffected. Vinyl loses impact resistance below 40 degrees and cracks more easily in winter.
If you are selling in the next 5 to 10 years and budget is tight, good quality insulated vinyl in a mid-tone color gives you the best return. Stay away from dark colors that will fade before you close.
If you are the long term owner, the neighborhood supports it, and you have the budget, fiber cement is almost always the right answer. It is the last siding you will install. It looks better on day one and still looks right 20 years later.
