Retaining Wall Construction & Repair in Quincy, MA

A retaining wall contractor that knows Quincy

Quincy sits in South Suburban (Norfolk County), and projects here near Adams National Historical Park need to handle a specific blend of weather and soil. Quincy granite, quarried locally since the 1820s, was used in Boston's Bunker Hill Monument (Charlestown) and many historic New England landmarks. We've built retaining walls throughout Quincy Center, Wollaston, and the rest of town with that local knowledge baked in.

JL Masonry has been serving Quincy homeowners for over 15 years. Our crews understand the dense triple-decker aesthetic that dominates Quincy Center, and we stock material samples that match Quincy's historic vocabulary.

Retaining Wall questions, answered

How tall can a retaining wall be?

We build walls from 2 feet (garden walls) up to 12+ feet (engineered terraces). Walls over 4 feet require an engineer's stamp and permit.

What's the most important part of a retaining wall?

What you can't see — drainage. A wall without proper perforated drain tile, crushed-stone backfill, and geotextile separator will fail within 5–10 years no matter how good the face stone looks.

Can you build into a slope or only against existing soil?

Both. We can cut into a hillside for a benched terrace or build a freestanding wall to create a level yard above grade. Each requires different drainage and structural approach.
