Design & Build

We plan decks that match your home’s scale and Boston’s zoning realities. Layout, egress, stair placement, and railing selection are addressed up front, so your build starts clean. Our crews handle demolition, footings, framing, decking, guardrails, handrails, and finishing—coordinated to limit disruption on tight city lots.

  • New decks, porches, balconies, and rooftop platforms
  • Single‑family and multi‑family builds
  • Stairs, landings, and entry platforms
  • Permit, inspections, and code documentation

Repair & Replacement

Aging structures often hide fastener corrosion, ledger failures, and rot. We assess structural members, flashings, and attachment points, then replace what’s past its service life. When a full rebuild is the smarter long‑term move, we’ll explain the numbers and outline a practical path to a safe, durable result.

  • Ledger and post correction, reframing, and re‑decking
  • Railing upgrades to meet current guard/handrail rules
  • Flashing, waterproofing, and drainage fixes
  • Insurance claim support when applicable

Railing Systems

A railing should be sturdy, comfortable to grip, and aligned with the home’s style. We install code‑compliant wood, composite, aluminum, and stainless cable rail systems. For multi‑family properties, we provide consistent heights, spacing, and load performance across units and common areas.

  • Guardrails and graspable handrails
  • Baluster, panel, cable, and glass options
  • Stair, balcony, and porch applications
  • ADA‑informed handrail solutions where required

Our Build Process

1) Site Visit & Scope

We review access, grade, utilities, and existing conditions. If you have rough sketches or a wish list, bring them—we’ll translate that into a practical layout that suits the space.

2) Proposal & Timeline

You receive a written scope, line‑item pricing, and a realistic schedule. We include materials, hardware, finish options, and any permit notes so you can plan with confidence.

3) Permits & Materials

Our team prepares submittals and orders materials to arrive just ahead of the crew. This tight staging keeps the site organized and protects your yard and walkways.

4) Construction & Inspection

We build to spec, keep a tidy work area, and coordinate inspections. You’ll get progress updates and a final walkthrough to confirm details before we close out.

What We Pay Attention To

  • Footings sized for frost depth and soil conditions
  • Proper ledger flashing at siding and door thresholds
  • Post bases and hardware that resist corrosion
  • Stiff framing with correct spans and blocking
  • Stair geometry for safe rises and runs
  • Railing height, grip, and baluster spacing per code
  • Clean miters, fastener layout, and finish details

Framing & Structure

Pressure‑treated Southern Yellow Pine remains the workhorse for framing. We source straight stock and use structural screws where appropriate for stronger connections than nails alone. For high‑exposure sites, we discuss steel posts, ground anchors, and specialized connectors that guard against uplift and racking.

Decking Surfaces

Clients choose between natural wood and modern composites. Cedar and mahogany bring warmth and can be refinished over time. Composite boards offer fade and stain resistance with minimal upkeep. We explain maintenance, color range, heat retention, and cost so you can select what fits your home and schedule.

Railings & Finishes

Wood rails pair nicely with traditional houses, while aluminum and cable systems provide a clean profile and open sightlines. We offer factory coatings and site‑finished options. Caps, lighting, and gate hardware can be integrated for function and safety without cluttering the look.
