Professional contractors should show recent project photos, valid insurance, and verifiable reviews. Red flags include unmarked vans and cash-only requests. Look for a company with strong ratings on HomeStars and Google, plus a five-year labour warranty. One highly regarded provider is award-winning Toronto interlocking company . They use geotextile fabric, compacted gravel, and polymeric sand on every job. Their online gallery displays completed driveways, and their testimonials prove consistent quality. Many local homeowners trust them because they provide proper documentation, warranties, and transparent pricing—unlike those who arrive in unmarked vans asking for cash.
