1. How much does it cost to replace siding?
Siding cost depends mostly on the material, the size of your home and how much prep work the walls need. As a rough guide, installed vinyl siding often runs about $5 to $12 per square foot, and fiber cement (like James Hardie) often runs about $8 to $15 per square foot or more. Premium materials such as cedar or engineered wood can cost more.
Factors that move the price up or down include:
- Total wall area and the number of stories (taller homes need more staging and labor)
- Removal and disposal of old siding
- Repairs to rotted sheathing or framing found during tear-off
- Trim, soffit, fascia and window/door wrapping
- Insulated vinyl or upgraded housewrap
The only way to get a real number is an on-site measurement. We provide free, no-pressure estimates with an itemized breakdown so you can see exactly where the money goes.
2. How long does siding last?
With proper installation, most siding materials last for decades:
- Vinyl: about 20 to 40 years
- Fiber cement: about 30 to 50 years
- Wood: 20 to 40 years or more, but only with regular painting or staining
- Aluminum: about 30 years, though it dents easily
In Southern Maryland, the biggest threats to siding life are moisture, intense summer sun that fades and warps vinyl, and wind-driven rain from coastal storms. Good flashing and a proper water-resistant barrier behind the siding matter just as much as the siding itself.
3. Is vinyl or fiber cement siding better?
Both are good choices. The right one depends on your budget and priorities.
Vinyl siding is the most affordable option, needs very little maintenance, never needs painting and comes in many colors and profiles. Its downsides are that it can crack in cold weather if hit and can warp near grills or reflected sunlight.
Fiber cement siding costs more up front but is very durable. It resists fire, insects and impacts, and has a more authentic wood look. It needs repainting roughly every 10 to 15 years, depending on the finish.
Many Calvert County homeowners choose vinyl for value and fiber cement for maximum durability and curb appeal. We’re happy to show you samples of both.
4. How do I know if my siding needs to be replaced?
Watch for these warning signs:
- Warped, buckled, cracked or loose panels
- Soft or rotting spots when you press on the siding or trim
- Mold, mildew or algae that keeps coming back
- Peeling paint or wallpaper on interior walls, which can mean moisture is getting behind the siding
- Heavy fading or chalky residue
- Rising heating and cooling bills
- Holes from hail, woodpeckers or insects
One or two damaged pieces can usually be repaired. Widespread damage, or any sign of moisture behind the walls, is a good reason to get a professional inspection.
5. Can you repair just one section of siding?
Yes. Small areas of storm or impact damage can often be repaired by replacing individual panels or boards. The challenge is matching: siding fades over time, and manufacturers discontinue colors and profiles. A brand-new panel may not match your weathered siding exactly.
If the damaged area is on a highly visible wall, or the original product is no longer made, replacing a full wall or the whole house may give a better-looking result. If the damage is from a storm, your insurance policy may affect how matching is handled, so it’s worth having the damage documented first.
6. Does homeowners insurance cover siding damage?
Homeowners insurance typically covers siding damaged by a sudden, accidental event such as hail, high winds, a fallen tree or fire. It typically does not cover damage from age, normal wear, poor maintenance or long-term moisture problems.
If you think storm damage hit your siding:
- Take photos as soon as it’s safe
- Prevent further damage (for example, tarp or cover open areas)
- Have a qualified contractor inspect and document the damage
- Contact your insurance company to start a claim
Your deductible and coverage details depend on your specific policy, so review it or ask your agent. We help homeowners document storm damage and work through the insurance claims process.
7. Can new siding be installed over old siding?
It’s sometimes possible, but we usually don’t recommend it. Installing over old siding can hide rot, mold and insect damage that keeps getting worse behind the new siding. It also makes it harder to install proper flashing and a new water-resistant barrier, and it can make window and door trim look recessed.
A full tear-off lets us inspect the sheathing, fix problems, add new housewrap and give you a cleaner, longer-lasting installation.
8. Does new siding increase home value and energy efficiency?
New siding is one of the most noticeable upgrades you can make, and exterior projects like siding replacement consistently rank among the better-returning remodeling projects at resale. Fresh siding also makes a strong first impression on buyers.
For energy efficiency, the biggest gains usually come from what goes behind the siding: a quality housewrap that blocks air leaks, and insulated siding or foam backer board. Many homeowners notice a more comfortable home and fewer drafts after a full siding replacement.
9. How long does siding installation take?
Most single-family homes take about 3 to 7 working days, depending on the home’s size and complexity, the material and the weather. Fiber cement generally takes longer than vinyl because it’s heavier and needs more cutting and finishing.
You don’t need to leave home during the work. We’ll walk you through the schedule before we start and keep the site clean each day.
10. What is the best time of year to replace siding in Maryland?
Spring and fall are ideal in Southern Maryland because mild temperatures and lower humidity make for comfortable, efficient installation. That said, siding can be installed most of the year.
Vinyl gets more brittle in cold weather, so experienced installers take extra care when cutting and fastening it in winter. Vinyl also expands in summer heat, so it has to be hung loosely enough to move. Fiber cement and its paint have their own temperature guidelines. Because spring and fall book up fast, it’s smart to get your estimate a few weeks ahead.
