Retaining Walls in Cohasset, MA
Looking for retaining walls in Cohasset, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Cohasset and the rest of Norfolk County from our Boston base. Cohasset seaside properties need hardy stonework: terraces, stairs, and seawall repairs.
Housing in Cohasset includes tight lots with shared driveways and close neighbors, and road salt and plow damage every winter is what wears this masonry down. That is why our retaining walls work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. A retaining wall fails from water, not weight. We build with proper base depth, geogrid reinforcement where needed, and drainage behind the wall so it stays plumb through New England winters.

Yes. Ultimate Boston Masonry is licensed, fully insured, and family-owned with 5 years of experience on Greater Boston brick and stone.
Do I need a permit for a retaining wall?
Most Massachusetts towns require a permit above four feet, and many require engineered drawings. We tell you the local rule and handle the filing.
Why is my existing wall leaning?
Almost always a missing drain line or an undersized base. Hydrostatic pressure behind the wall pushes it out over a few freeze cycles.
