You describe the tree by phone, email, or form. 2. We send a free written quote within 24 hours — itemized, fixed-price, with Aurora Bylaw 6362-21 permit fees included. 3. The crew arrives in marked trucks with full PPE. 4. We file the permit, do the work, haul the wood, and clean up. No on-site sales pressure. No drive upcharge for Newmarket, Richmond Hill, or King City. Insurance-claim documentation provided on every storm-damage job.
