When work goes smoothly, reviewers report professional execution and solid results. But a significant split emerges: early praise contrasts sharply with later complaints about crew behaviour on multi-unit sites, ignored warranty claims, and structural failures discovered in the years after completion.
Based on limited recent reviews, so treat this as low-confidence.
Sinclair Contracting has built a foundation and chimney repair business with 30 years of warranty backing and a broad service list spanning foundation work, waterproofing, and chimney services. Review detail is limited, but the business reports top ratings across Google, HomeStars, Yelp, and Bark.
Reviewers consistently praise Cossette's professionalism, speed, and attention to detail on everything from roof replacements to leak repairs. The team cleans thoroughly after jobs and answers questions readily. One complaint stands out: nails and debris left on a neighbour's property after a job, though most reviews emphasize their tidiness.
Perfect 5-star average across three reviews, though detail is limited. The business holds RBQ and CCQ credentials and claims over 25 years serving the Hull-Gatineau and Ottawa region.
