Retaining Wall Construction in Danvers, MA
Engineered fieldstone and block retaining walls that hold sloped Danvers yards in place — built to the 48-inch frost line, drained properly, and permitted when the code requires it.
A retaining wall is the one structure on your property that’s actively holding something back — soil, water, and the grade itself. Built wrong, it leans and fails within a few Danvers winters. The difference is almost never the stone you see; it’s the base, the drainage, and the reinforcement you don’t. We build walls in Danvers the way they should be built for New England: compacted footings below the 48-inch frost line, gravel backfill with a perforated drain, and geogrid reinforcement where the height calls for it.

The AB Mendez Standard
How a Danvers retaining wall gets built
Assess the slope
We read the grade, soil, and water flow and flag whether a permit or historic review applies.
Excavate & base
We dig below the frost line and compact a crushed-stone base.
Build & drain
We set the wall with gravel backfill, a perforated drain, and geogrid reinforcement.
Backfill & finish
We backfill, re-grade, and clean up.
Permits in Danvers
When a Danvers retaining wall needs a permit
In Danvers, a retaining wall over 4 feet (footing to top) — or any wall supporting a surcharge — requires a building permit and engineered drawings through Danvers Inspectional Services. For work on or near a historic structure the Danvers Historical Commission’s demolition-review bylaw can apply, and wetland buffers near the rivers fall under the Danvers Conservation Commission. We handle the permit, the engineering, and any hearing.

From the owner
“Nine times out of ten, a failed retaining wall didn’t fail because of the stone — it failed because nobody dealt with the water.”
Drainage is the whole game with retaining walls. A wall without a proper base and a way for water to escape will heave and bulge no matter how good it looks on day one. When I build a wall in Danvers, the drainage is engineered before the first stone goes down — Anibel Mendez
Retaining Walls FAQ
Common questions
Do I need a permit for a retaining wall in Danvers?
If it’s over 4 feet or supports a surcharge, yes — a building permit and engineered drawings are required. We handle all of it.
How tall can a wall be without engineering?
Generally up to 4 feet, as long as it isn’t holding back a driveway, pool, or other surcharge.
What’s the best material for my slope?
It depends on height, look, and budget. Fieldstone suits historic Danvers homes; block gives clean lines; concrete handles the tallest loads.
How long should a retaining wall last?
Built correctly — proper base, drainage, and reinforcement — decades.
How much does a retaining wall cost in Danvers?
Most installed walls run roughly $30–$75 per square foot depending on material, height, drainage, and access.
