Best Fieldstone Foundation Repair in New Hampshire
How we rank (the Bedrock Standard). Every figure below is dated and sourced; star ratings change over time. We read five-star share together with review depth, so a near-perfect share on a large review base counts for more than a perfect score on a small one.
The deepest verified review base in this set at 4.8 across 676 Google reviews as of June 2026, paired with current New Hampshire fieldstone examples that document an auxiliary wall with SmartJack support and granite-foundation repointing and parging. Erickson is locally owned in Hudson and carries a clean BBB record. Its smaller Yelp sample is lower at 3.3 across 19 reviews, and fieldstone-specific mortar, structural design, and written warranty terms still require confirmation.
The most explicit specialist page in the set, publishing fieldstone mortar repointing, masonry reinforcement, foundation bracing, stone realignment, and waterproofing for New Hampshire. Its dated Google record is 4.8 across 51 reviews as of April 2026, with no one-star reviews in that distribution. It ranks behind Erickson on review depth and documented project detail; the exact mortar specification, structural responsibility, and fieldstone-specific warranty were not independently retrieved.
The strongest proportional Google record here at 5.0 across 262 reviews, all five-star in the August 2026 distribution. Its current structural page includes a customer account describing repair of crumbling, settlement-related damage in an old fieldstone foundation and installation of a lally column. 603 ranks third because the evidence is a contractor-published customer account rather than a dedicated fieldstone method page, and no fieldstone-specific mortar system or written warranty was independently retrieved.
Also serving the area
The national option through a Hooksett branch, with a deep local Google record at 4.9 across 567 reviews and a current fieldstone page that publishes drainage, sump, and structural-reinforcement work.

Confirm the local contracting entity, masonry scope, structural responsibility, and warranty process.
