Ellicott City's siding takes a beating that homeowners in flatter towns don't deal with. The 1960s–1980s split-levels and colonials that climb the hills around Dunloggin, Font Hill, and Valley Mede sit on wooded, north-sloping lots where shaded walls stay damp for days after a rain, and the older masonite and early vinyl siding on those homes streaks green with algae and cups where moisture got behind it. Out toward Centennial, Waverly Woods, and Turf Valley the newer builder-grade vinyl has faded and gone brittle, and near historic Main Street and the Patapsco the older homes need siding that respects their character while finally sealing out water.
We install James Hardie fiber cement and quality insulated vinyl, and we start where it counts — behind the panels. Old siding comes off so we can inspect the sheathing, because on these hillside homes with poor drainage there's often soft OSB or plank where water tracked in for years. We call out any bad sheathing before we cover it and put a per-sheet decking allowance in writing so you know the number up front, not after. Then full housewrap goes on as a drainage plane, every window, door, and penetration gets flashed, and panels are fastened to spec so the wall can shed water and dry the way the manufacturer designed. On the shaded, north-facing elevations that grow algae, fiber cement's ColorPlus finish or an algae-resistant vinyl keeps the wall looking clean far longer.
Every project is installed by our own W-2 crews, never subcontracted, and backed by a written workmanship warranty alongside the Hardie or vinyl manufacturer warranty. We pull Howard County permits, and for the older homes near the historic district we're careful to match profiles, reveals, and trim details where it matters — and we'll flag any historic-review requirements before the order goes in. You get a written scope and price before we schedule, so there's no guessing about what's included. Apper Construction has been family-owned since 2016, and we're on these Ellicott City hills every week — we can tell a Dunloggin split-level from a Waverly Woods colonial or a Turf Valley build the moment we walk the wall, and that experience shows up in a cleaner, longer-lasting install.
Most Ellicott City siding projects run $12,000–$34,000 installed depending on square footage, whether you choose James Hardie fiber cement or insulated vinyl, and how much sheathing or trim needs replacement. We inspect the wall, quote a per-sheet decking allowance in writing, and give you a full written scope before scheduling. Call 410-508-6141.
