Cracked panels and open seams look like a paint-and-patch job. What's happening behind them is the expensive part. Typical DMV ranges below.
Water gets behind the wall
One cracked panel or open J-channel wicks water past the housewrap. Sheathing rots invisibly for years — you find out when a wall goes soft.
Open walls + replace sheathing: $4,000–$12,000Your HVAC pays the difference
Gapped, warped siding leaks air at every seam. Heating and cooling loss through a poor envelope is a bill you pay every single month.
Typical wasted energy: $200–$500 per yearMoisture invites mold & pests
A damp wall cavity is exactly what mold, carpenter ants, and mice are looking for. Remediation is a separate licensed trade with separate pricing.
Mold remediation: $2,000–$6,000Buyers see it from the street
Faded, hail-pocked, or mismatched siding is the first thing a listing photo shows. Buyers discount for it — usually by more than the siding costs.
Typical resale discount: $5,000–$15,000Typical ranges, not quotes. The free inspection tells you — with dated photos — whether your siding is cosmetic, compromised, or claimable.
Curb appeal you see, performance you feel
Curb appeal & resale
New siding is the single biggest exterior facelift a house can get — fresh color, crisp trim, and lines that read as a recently updated home the day it goes on the market.
A tighter, drier envelope
We don't just hang panels. We inspect the sheathing, install a proper housewrap and flashing at every window and door, and stop the air infiltration that drives up heating and cooling bills.
One accountable crew
Roof, siding, gutters, and trim handled by the same licensed company — no finger-pointing between trades when the elevations have to line up.
Vinyl vs. fiber cement
Insulated vinyl
The value leader — color-through panels that never need repainting, low maintenance, and insulated backing options that add R-value. A wide profile and color range to match any DMV neighborhood.
Fiber cement
James Hardie-style board that reads as premium, takes paint beautifully, and resists impact, rot, and fire far better than vinyl. The choice when you want a wood look that lasts decades.
Trim, soffit & fascia
A siding job is only as clean as its details — wrapped windows, new corner posts, soffit and fascia, and matched accessories so the whole elevation finishes tight.
| Insulated vinyl | Fiber cement (James Hardie-style) | Engineered wood (LP-style) | |
|---|---|---|---|
| Relative cost | The least expensive of the three | The most, and the longest-lived | Between the two |
| Expected life | 25–40 years | 30–50 years | 25–35 years |
| Maintenance | None — color-through, never repaint | Repaint every 12–15 years; takes paint beautifully | Repaint every 10–15 years; factory finishes available |
| Impact & fire | Good; can crack in severe hail | Excellent — resists hail, rot, and fire | Very good impact resistance; treated against rot and pests |
| Best for | Value, low maintenance, fast payback | Premium wood look, forever homes, resale punch | Real wood grain warmth, lighter and easier to detail than fiber cement |
*The vinyl and engineered-wood columns are typical Maryland market ranges. The fiber cement column is our own published rate and it is the one that applies to your quote: $16.50 per square foot installed for James Hardie ColorPlus, plus $5.20 per square foot for HardieTrim at windows, doors and corners, $2.40 per square foot to remove and haul the existing siding, and $1.35 per square foot for a full taped weather-resistive barrier. Sheathing repair is $2.25 per square foot and is billed only where rot is actually found. Wall area, stories and trim scope move the total; we measure the elevations and quote both systems side by side, in writing, before anything is ordered.
Looking to replace aluminum siding? Many Maryland homes built before 1980 still wear their original aluminum panels — and hail leaves permanent dents in aluminum that insurers routinely recognize as storm damage. We handle aluminum siding removal and replacement across Maryland: the old aluminum comes off, the sheathing underneath gets inspected, and modern insulated vinyl or fiber cement goes on — with every dented elevation photographed and documented in case your policy covers the upgrade.

That's a different playbook
If a recent storm crossed your county, siding is often part of the damage — and it's a different process. We keep all storm and insurance guidance on one page. See how storm restoration works →
From elevation walk to a sealed envelope
A siding job succeeds or fails at the details you never see again — housewrap, flashing, sheathing. Here's the order we do it in, so those details are right before a single panel hides them.
Every elevation, documented
A specialist walks all four sides — panels, seams, caulk lines, trim — with dated photos. Hail-pocked or wind-torn siding gets flagged as potentially claimable while it still is; ordinary wear gets called ordinary wear.
Day 1 · FreeMaterial, color & trim selection
Insulated vinyl, fiber cement, and engineered wood priced side by side against your actual wall area — with profile and color samples you can hold against the brick, not squint at on a screen. $0-down financing from 12 to 180 months (on approved credit) is quoted alongside.
Your call, real numbersPermits, ordering & prep
We pull any required permits, order to your measurements, and protect landscaping and walkways before the first panel comes off. If a storm claim is involved, adjuster meetings happen in this window.
Scheduled around youStrip, inspect, wrap, hang
Old siding comes off, sheathing gets inspected and replaced where it's soft, then proper housewrap and flashing go on at every window and door before new panels, wrapped trim, soffit, and fascia finish each elevation tight.
3–5 working daysWalkthrough, cleanup & warranty
Magnet sweep for fasteners, every scrap hauled, and a walkthrough of all four elevations against the photo record — then the manufacturer's warranty plus our 2-year workmanship warranty, in writing.
In writingCredentials on paper, not just on the truck
Family-owned and operating across Maryland since 2005. Every contract carries our license numbers, every crew is fully insured, and every job is backed in writing.
A $12,000 wall repair starts as one cracked panel
Siding failures are cheap to fix the year they happen and expensive every year after. Our free annual exterior inspection walks every elevation — panels, seams, flashing, caulk lines — and documents anything storm-related while it's still claimable. It's a $400 service. You pay nothing, and the dated photo report is yours either way.
Book My Free Inspection →Siding on Bethesda and Montgomery County houses
Much of Bethesda inside the Beltway is 1920s–1950s colonials and capes on modest lots, with 1990s-onward tear-downs and rear additions between them. On the older houses, the siding you see is often not the first layer: what is underneath, and the condition of the sheathing, decides whether we strip to the wall or not. We open a test section and photograph it before we price.
Parts of Bethesda and Chevy Chase sit inside designated historic districts. In Montgomery County, exterior changes to a house in a designated historic district go through the Historic Preservation Commission’s Historic Area Work Permit (HAWP) before work starts, and siding material and profile are exactly what that review looks at. We check your address against the historic designations before you choose a product.
Rockville and Gaithersburg run their own permit offices: the City of Rockville (240-314-8200) and the City of Gaithersburg (301-258-6330). Elsewhere in the county, including Bethesda, Potomac and Silver Spring, it is Montgomery County DPS (240-777-0311).
Straight answers
Vinyl or fiber cement — which should I pick?
Vinyl is lighter on budget and maintenance; fiber cement takes paint, reads as premium, and resists impact better. We quote both so you compare real numbers.
Can insurance cover siding?
If it's storm damage, often yes — siding is a standard claim line item. We document all elevations during the free inspection, provide the documentation your insurer needs, and meet your adjuster on site. On an approved claim, your deductible is typically your out-of-pocket cost. Your policy and carrier determine coverage.
Will new siding lower my energy bills?
Insulated and properly housewrapped siding reduces drafts and air infiltration. Combined with sealing the envelope, most homeowners notice steadier indoor temperatures.
What does new siding cost in the DMV?
What a wall costs is set by its area, the number of stories, and how much trim and detail work goes with it — which is why we measure before we quote. Your free inspection produces exact side-by-side numbers in writing — and $0-down financing is available.
How long does a siding job take?
Most single-family homes take 3–5 working days including trim, soffit, and cleanup. We pull any required permits and protect landscaping while we work.
Is engineered wood siding worth considering?
Increasingly, yes. It gives you real wood-grain warmth, weighs less than fiber cement (which keeps labor and detailing cleaner), and modern treatments handle rot and pests well. It sits between vinyl and fiber cement on price — which is exactly why we quote all three against your actual wall area instead of pushing one.
Do you replace aluminum siding?
Yes — aluminum siding removal and replacement is one of our most common siding jobs in MD. Pre-1980 homes often carry original aluminum siding, and hail dents it permanently, which insurers routinely treat as storm damage. We remove the old aluminum panels, inspect the sheathing beneath, and install modern insulated vinyl or fiber cement — documenting every dented elevation with dated photos for your claim.
Do you do siding near me in Bethesda and Montgomery County?
Yes — the same local crews that handle our roofing cover Bethesda, Chevy Chase, Potomac, Rockville, Silver Spring, and the rest of Montgomery County. As a Montgomery County siding contractor we also know which HOAs and historic districts have color and material rules — and we handle that paperwork.
Should I do the roof and siding together?
If both are near end of life, yes — flashing, housewrap, drip edge, and trim all interlock where roof meets wall, and one crew doing both means that joint is detailed once, correctly. Start with the 60-second instant quote for the roof side, and the free inspection prices the combined project with one $0-down financing plan.
