What reviewers think

Mattamy's 1.8-star rating reflects deep dissatisfaction. Owners report chronic issues: furnaces that fail within months, roofs leaking from improper shingle installation, kitchen pipes sloped incorrectly into units, inadequate insulation causing constant neighbor noise. Warranty claims languish unanswered; staff dismiss complaints after sale. One builder praised responsiveness; 43 others describe negligence, overpriced upgrades charged as "standard," and refusals to correct mistakes.
