Looking for retaining walls in Coolidge Square in Watertown, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Watertown and the rest of Middlesex County from our Boston base. Watertown homeowners call most often for walkway resets, front steps, and chimney crowns.
Housing in Coolidge Square in Watertown includes older brick multi-families and colonials built before 1940, and wind-driven rain from nor'easters 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.
