Elegant, engineered stone and retaining walls for property lines, grade changes, terracing and landscaping that hold strong for decades. Proudly serving Waltham and the surrounding Greater Boston area.
YellowStone Masonry Group is the Greater Boston's go-to masonry team, and Waltham, MA is right in our backyard. Half a century of experience means we build stone and retaining walls to survive coastal weather, nor'easters, and wide temperature swings that stress brick, block, and stone and open up mortar joints.
Our Waltham customers keep coming back and referring neighbors because we build stone walls to outlast the trends. Proper prep, honest advice on repair-versus-replace, and a finish you will be proud to show off.
A failing, leaning or bulging wall that is one heavy rain away from collapsing and taking your landscaping with it
Erosion and washouts on a slope that keep eating your yard and undermining patios, driveways and foundations
Standing water and frost pressure building behind a wall that was built with no drainage and is now pushing apart
Wasted, unusable sloped yard that could be terraced into flat, functional, beautiful space
Engineered retaining walls with proper footing, batter, drainage stone and filter fabric that handle real soil pressure
Hidden perforated drains and weeps that relieve water and frost pressure so the wall does not blow out
Natural stone, granite and segmental block options to match your landscape and home
Terracing that turns a useless slope into flat, usable garden and living space
Erosion control that protects your yard, hardscaping and foundation for the long term
Structural builds that routinely last 50 to 100 years when done right
We assess the grade, soil and water flow, and recommend the right wall type and material for the load.
We plan footing depth, batter, drainage and reinforcement for the height and pressure your wall must hold.
You receive an itemized estimate covering excavation, base, drainage, materials and backfill.
We build on a compacted base with full drainage and proper setback, course by course, and restore the grade.
In Massachusetts, taller retaining walls (often over 4 feet) typically require a permit and engineering. We advise you on local requirements and build to code.
Almost always from missing drainage and a poor base. Water and frost build pressure behind the wall and push it out. We build with drainage stone, filter fabric and perforated pipe so that pressure is relieved.
A freestanding stone wall defines space or property lines. A retaining wall holds back soil and a grade change, so it needs footing, drainage and engineering. We build both.
