Not enough recent reviews yet to synthesise a reliable sentiment read for this business.
Based on limited recent reviews, so treat this as low-confidence.
Reviewers praise the fair prices and solid workmanship. Several clients have hired the team more than once and sent friends their way. The most-mentioned work is fencing, not decks, so deck-specific feedback is thin.
Reviewers are not the subject here. Customers consistently describe quick installs, straightforward communication, and tidy crews who clean up before they leave. Most reviews come from fence projects, and the praise is steady across 37 ratings averaging 4.9. One reviewer felt let down by a short extension that kept getting pushed back. Named owner-led work stands out in many stories. Reviews describe wood privacy fences, a 600-plus foot residential job finished in about a day, and roughly 800 feet of commercial fence in Belmont. One reviewer praised a deck replacement, and the business lists deck construction among its services.
Blackrock Building Group earned five stars across 7 Google reviews. Reviewers describe a professional crew that communicates well, finishes on time, and does careful, high-quality work on a range of projects.
