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.

Storm Damage?

That's a different playbook

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, work directly with your insurer, and meet your adjuster on site. Most homeowners pay only their deductible.

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.
