What recent reviews say

Most reviewers report smooth, professional service with fast response and clean sites, especially for asbestos and mold work. One serious complaint documents a 16-month delay on a two-week job and unpaid subcontractors, creating real doubt about project management.

Based on limited recent reviews, so treat this as low-confidence.
