With tree services, especially expert jobs such as heavy pruning, storm damage restoration, or tree removal, you want to make sure you choose a professional. Look at the following criteria: Certification: Most qualified arborists have an ISA certification, an industry-standard that declares they are equipped to handle all types of tree care jobs. Experience and recommendations: Choose a trustworthy team that has been in business for a while and has positive client reviews. Insurance: Some tree services, such as felling and removal, are risky even if the arborist follows best industry practices. For peace of mind, ask the arborist if they have personal, property damage, and workers’ compensation insurance. Above all, look for an Ottawa arborist who is transparent, polite, responsive, and ready to answer all your questions.
