Clapboard Siding Installation in Massachusetts
Clapboard siding installation and replacement across Massachusetts. Alfa Construction installs horizontal lap siding — the defining New England profile — in fiber cement, engineered wood, cedar, and vinyl, with the consistent reveal and crisp shadow lines that give clapboard its classic look. We take full-exterior re-sides, not patch repairs.
Clapboard is the siding profile that built New England. Long, horizontal boards lapped one over the next, each course casting a clean shadow line down the wall, give colonial, Cape, and farmhouse exteriors their unmistakable character. Alfa Construction installs clapboard siding the way it is meant to be installed — with disciplined attention to the reveal, the overlap, and the weather details that separate a wall that lasts from one that fails. We work in James Hardie fiber cement, engineered wood, natural cedar, and premium vinyl clapboard, and we help you choose the material that fits your home, your exposure, and your budget. Every project starts with an honest look at what is behind your existing siding: we inspect the sheathing, check for hidden moisture, and confirm the wall is sound before a single board goes up. Then we install a continuous weather-resistive barrier, flash every opening and transition correctly, and hang each course with a consistent reveal and proper overlap so water sheds the way clapboard is designed to shed it. Pre-primed and factory-finished options keep the finish crisp for years. Whether your original clapboard has surrendered to decades of nor'easters or you simply want the authentic horizontal-lap look done right, we deliver an exterior that protects your home and looks like it belongs on a Massachusetts street.
Common Problems We Solve
Original wood clapboards that have cupped, split, or pulled loose from the wall, breaking the clean horizontal lines that give the profile its appeal
Inconsistent reveals and sloppy overlaps from a previous installer that leave the wall looking wavy and let water work its way behind the boards
Peeling, blistering paint on old clapboard that demands scraping and repainting every few years and never truly stays sealed
Water staining, soft sheathing, and rot hidden behind failed laps where flashing and overlap were never detailed correctly
A tired exterior whose faded, mismatched clapboard drags down curb appeal on a street where the horizontal-lap look is expected
Our Clapboard Process
Free Exterior Inspection & Estimate
We walk your home, study the existing clapboard, and check for cupped boards, failed laps, and any hidden moisture in the sheathing behind them. We talk through the look you want — reveal width, material, finish — and give you a detailed written estimate covering materials, labor, timeline, and warranty.
Clapboard Material & Reveal Selection
We bring samples of fiber cement, engineered wood, cedar, and vinyl clapboard so you can compare grain, color, and profile against your roof and trim. We help you settle on a reveal width and finish — pre-primed for site painting or factory-finished — that suits your home's era and the rest of the street.
Removal & Substrate Preparation
Our crew strips the old clapboard down to the sheathing, hauls away the debris, and inspects what is underneath. Any rot or soft spots are repaired, and we install or replace the weather-resistive barrier and flashing so the wall is sound and watertight before new lap siding goes on.
Clapboard Installation
We snap layout lines and hang each course with a consistent reveal and the correct overlap so the wall sheds water the way clapboard is meant to. Boards are fastened to manufacturer spec, butt joints are detailed and flashed, and every window, corner, and transition is treated where water infiltration is most likely.
Final Inspection & Warranty
We sight down every course to confirm the reveal stays true, seal all penetrations, and verify that flashing and laps are doing their job. We walk you through the finished exterior, cover finish care, and hand over warranty documentation for both the material and our labor.
