The Cost of Waiting

Failed siding doesn't stay a cosmetic problem

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–$12,000

Your 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 year

Moisture 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–$6,000

Buyers 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–$15,000

Typical ranges, not quotes. The free inspection tells you — with dated photos — whether your siding is cosmetic, compromised, or claimable.

What You Get

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.

Materials We Install

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.

*Typical DMV ranges for an average two-story home — wall area, stories, and trim scope move the number. We quote both systems side by side, in writing.

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.

Storm Damage?

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 →

How It 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.

1

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 · Free
2

Material, 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 numbers
3

Permits, 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 you
4

Strip, 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 days
5

Walkthrough, 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.

Why the Inspection Matters

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.

Common Questions

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?

Typical whole-home projects run $12,000–$20,000 in insulated vinyl and $18,000–$35,000 in fiber cement, depending on wall area, stories, and trim scope. 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.
