What We Do

Stone, brick,
and concrete.

Our Services

Six things we do — all of them well.

Every project we take on falls into one of these six categories. We don't subcontract. We don't try to be everything to everyone. We do masonry — and Nilson has been doing it across Greater Boston for over 18 years.

01 / Stone Walls
Stone Walls

Built from real stone — not veneer panels.

Whether it's a freestanding garden wall, a structural retaining wall, or a decorative facade, we build with full-depth natural stone. Every piece is hand-set. Every joint is mortared properly. The result lasts decades, not seasons.

  • Natural fieldstone, granite, and ledgestone
  • Mortared and dry-stack construction
  • Custom heights, lengths, and finishes
  • Frost-line footings on all retaining work

02 / Pavers & Walkways
Pavers & Walkways

Walkways that won't shift, sink, or settle.

Most paver problems start in the base. We dig deep, compact in lifts, and use proper edge restraints — so the path you walk on this fall will still be flat ten years from now. We work with Belgard, Techo-Bloc, Cambridge, and natural stone.

  • Front walks, side paths, and full driveways
  • Concrete pavers, clay brick, and bluestone
  • Curved or straight, banded or single-pattern
  • Polymeric sand and proper drainage

Stamped concrete by Dias Souza Construction
03 / Concrete Work
Concrete Work

Pours that hold up to New England winters.

Concrete is unforgiving — get the mix wrong, the base wrong, or the timing wrong, and you'll see cracks within a year. We pour to spec, finish properly, and seal what should be sealed. Stamped, broom-finish, or smooth — we do all three.

  • Stamped concrete patios and walkways
  • Foundations, slabs, and footings
  • Driveway pours and aprons
  • Decorative finishes and integral color

Paver patio by Dias Souza Construction
04 / Patios
Patios

Outdoor living spaces, built to last.

Your patio isn't just where the grill goes — it's where summers happen. We design and build patios that fit how you actually use your yard, with proper drainage, real edge work, and material choices that age well. From 200 sq. ft. to 2,000.

  • Paver, natural stone, and travertine patios
  • Built-in firepits, seating walls, and grill stations
  • Multi-level designs and curved layouts
  • Drainage planning and proper base prep

Granite steps by Dias Souza Construction
05 / Steps & Stairs
Steps & Stairs

Granite, bluestone, or paver — we set them right.

Steps take more abuse than any other masonry feature on a property. Foot traffic, frost heave, salt, ice — they all compound. We build steps that stay level for decades: full-depth treads, proper drainage, and risers tied into the wall, not just stacked.

  • Solid granite, bluestone, and concrete steps
  • Front entry, garden, and grade-change stairs
  • Stone-faced and freestanding designs
  • Code-compliant rise and run

06 / Retaining Walls
Retaining Walls

Engineered to hold — not just stack pretty.

A retaining wall has one job: hold back earth without failing. That requires proper engineering — drainage behind the wall, batter on the face, deadmen on tall walls. We've built dozens of them across the region, from 2-ft. garden walls to 8-ft. structural walls.

  • Natural stone, segmental block, and poured concrete
  • Engineered drainage with weep holes and aggregate
  • Tall walls (4ft+) with proper geo-grid
  • Tiered designs for steep grade changes
